Condensing Your Life on to a USB Flash Drive?
Fear the Clam asks: "My wife and I figure that if we plan for the worst, it'll never happen, so we've been putting together 'If public transportation bites it and we have two minutes to grab our stuff and start walking, never to return to NYC' getaway knapsacks. With luck they'll live in the closet forever.
Coincidently, this morning the New York Times has an article about what to take when you have to leave home in a big hurry [DNA verification required], and they suggest making a list of all of things like Social Security and credit card numbers, scanning birth certificates, marriage license and tax returns, and saving it all on a USB flash drive. Since this would be a complete identity kit, encryption is of utmost importance. What's the best solution? A flash drive that claims to encrypt or a platform-independent, self-extracting, encrypted file on a regular drive? Any suggestions for sturdy drives?" Of course, the choice of USB flash drive covers only a part of the problem. What other data would you put on this piece of "contingency hardware", and how would you protect the drive itself in case you did have to "swim for it"?
I've had three USB Flash Drives (Lexar, and two Sandisks) die on me, usually under a year, presumably a byproduct of the limited writes available to NAND memory.
My philosophy is that if DC is in such shape that I can never return, I really don't care about carrying around any personl data or very much anything else other than my life. We were having a discussion at work about whether our web backups could survive a nuclear attack... but if there's a nuclear attack, our website is the least of my concerns.
Paper.
Warning: this article may contain humor, sarcasm, parody, and perhaps even irony. Read at your own risk.
Most USB drives are pretty tough. I would make a copy or two and put it in a crush/water proof case like an Otterbox.
screw Social Security, they're going bankrupt anyway... on my emergency flash drive it's all about the pr0n.
I always swallow my USB identity drives
As far as encryption goes, for god's sake don't rely on anything the manufacturers ship. That stuff is meant to protect you from your average luser seeing files, not anybody who is honestly interested. Use Blowfish or Twofish for proper 2 way encryption.
Tatoo yourself in reeealy reealy little 1's and 0's. Tatoo your wife with the decryption key.
Wouldn't accepting scanned documents of identification open many a door for counterfeiters and scam artists, and even, dare I say, potential terrorists? *Raises terror alert to mauve*
You can store 5 minutes DV-quality porn on a 1GB stick.
If you are a man of questionable tolerance and determination, I suggest you use some kind of compression.
Oh - you mean like a "real real" drought or some other real natural disaster? Oh sorry.

There are a huge number of yeast infections in this county. Probably because we're downriver from the bread factory.
Well if your going to be all paranoid, you might as well get one of these.
Reality test... am I dreaming?
....is your friend. Don't trust the key vendor's utility. PGP can be accessed from any platform and isn't Win32-specific as the vendor's software is.
Upload it to the internet and let the world mirror it.
Would it not be better to simply keep a set of laminated copies of all those documents? In the case that you don't have access to a computer when you need it? There isn't always going to be a Kinko's or internet cafe nearby when you're in the midst of a terrorist attack or natural disaster the magnitude of which you are speaking.
feeling lonely? grab a balled up pillow for company
You could kill two birds with one stone, and get an iPod. That way you will not only have all of your important stuff, but you'll be able to groove to some sweet tunes while looting and pillaging.
Why not just email all that to yourself in a gmail account? Holds 2.5GB and counting, and you can get to it from anywhere. No need to worry about taking it along with you.
Just watch out for people trying to "brute force" your wife.
I've cloned my start-up drive and all my files onto a 250 GB firewire drive (and several bare IDE HDs stashed in strategic locations). Given that I can order a new computer by 2 AM Eastern and have it delivered the same morning, I can be back in business in no time. I like cloned drives because you can retain all the OS and user preferences.
Two wrongs don't make a right, but three lefts do.
That's why you should use the plausible deniability built into TrueCrypt. Giving the attacker the password to the outer volume (who has been robbed at knifepoint for a USB memory device? that'll be the day..), and they still still have no idea an entire volume of your real data is hiding in the noise that is the freespace of the aforementioned outer volume. the outer volume needs to be FAT and it can have innocuous stuff on there like fake financial documents.. Enjoy!

Having a smoking section in a restaurant is like having a peeing section in a swimming pool.
Technology isn't the answer to everything. Why not just take your important stuff, or good copies of said stuff, and put it in a safe deposit box? Then you just have to take your key with you when you run out of your house. And even if you lose your key, they can drill it open for a (hefty) fee.
Really, why make it so complex by trying to put everything on USB drive and trying to figure out what encryption's best and scanning everything and...and...and... It's a waste of time.
It's for Windows only, but I stumbled upon TrueCrypt found at http://www.truecrypt.org/ and really like it. And it's not only useful for USB drives, but can be used to create encrypted logical drives on a Hard Drive. For the really paranoid, the documentation even covers lots of stealthy ways to use it so as not to be detected.
I'm certainly no expert at encryption, but it seems pretty solid. Basically, it creates an encrypted container file and then mounts it as a logical drive when you open the file through the app. I've seen commercial counterparts such as StealthDisk, and I think TrueCrypt's interface is easier to use and its execution is more solid.
It's OSS and free as in beer and as in speech.
My mom always said, "Jim, you're 1 in a million." Given the current population, there are 7000 of me. God help us all!
You realise that you are posting on slashdot? "OK take it! Just don't puncture blow up betty!"
How immediate is the need for access to the information? The stronger the solution, the slower the access for the most part. Something that needs to be immediately accessable will need to be bundled with proper decryption tools (assume nothing better than Windows 95 will be available) on-stick.
Also related: what operating system are you using? Under Linux, you could use a loopback encrypted filesystem, for example, but under windows such would not be viable.
Are we assuming that the computer will be destroyed, or that we need to stick to a pure-RAM access system to prevent residue on the hard drive from being intercepted?
Are you willing to trust a corperate product for ease-of-use concerns?
Finally, how are you securing your original documents? Might it just be as easy to grab an organized safe-box as keep all the digital security on a digital form? Keep in mind that only origial copies are good for anything beyond having a reference point to start receiveing replacement copies of your stuff.
One more thing: How much of this is overkill? Keep in mind how cheap and simple it is to acquire copies of an arbitrary person's complete identifying information (I often see ways to do it under two hundred dollars, including original copies of all the usual certificates and plastic cards, which would cost less for a professional). A chain is only as strong as its weakest link, and in this case, with just some reasonable precaution, the path of least cost and difficulty is through more common means of aqusition than stealing a thumbdrive.
"Fight for lost causes. You may discover they weren't."
Assuming that your stuff is encrypted it should be pretty safe to put it almost anywhere.
1) Keep the latest copy on your iPod (or equivalent) if you tend to carry it all the time. That way you have it with you in case you can't go home.
2) Buy an extra USB drive and snail-mail it to your parents out in the boonies for safe keeping.
3) E-Mail it to yourself on Gmail or equivalent. But then I would double dog encrypt it. You may not want to put your most secret information there. But some of things could certainly go on there.
I would put all my ID stuff on there, all important papers and contracts, passport. Thumbprints and pictures of each other for the dreadful prospect that you may have to ID each other, or post pictures in the news paper for your partner. If you have any particular features such as a birth mark or a tatoo then it might be clever to take a picture of that as well. Medical records potentially. But you could also walk around and take pictures of your home for insurance purposes. All your important phone numbers and addresses to relatives.
If you are collecting all this information then you may want to invest the money in a fireproof safe as well.
Man, I didn't mean to sound so alarmist. I just thought it was a really great question.
The Internet is full. Go Away!!!
As others have pointed, more politely than I think they needed to, "In case of a nuclear war, nobody's going to give a damn." You'll be struggling just to live. So will everybody around you. Nobody's going to give a damn about your stupid keychain drive with the password to all your porno-sites on it. And if you make it to a part of civilization where you actually get to *use* the damn thing for it's intended purpose, being to recover your life's data, you'll be lucky to find somebody's computer with a compatible document format to read it, let alone figure out how to recover the data from your ultra-secure storage method.
Get a LIFE!
Hadn't thought of the otterbox (nice idea, makes sense). If your really trying to prep for something like this, consider making a non-magnetic copy also. While the odds of an EMP type disaster killing the drive (especially if stashed in a safe place) are slim, so are the odds of a nuclear disaster I guess.
Consider burning it to a CDR also. This is stuff that might have to be updated once a year (such as deeds or photos/contacts) anyway, so its not like the age of the media and deterioration will be a big problem.
A rule of thumb I've learned is that if your planning for stuff that occurs more then 2 standard deviations away from the mean, then chances are you want something that is (or can at least be considered virtually) full-proof. At the very least, the odds of all of the combined methods together have a lesser chance of failing then the original threat does of occuring.
We don't need an "overrated" so much as we need a "you completely missed the parent's point, dumbass..."
Ah. Scientologists.
I've had 4 of my 512 mb usb mem key's go through the wash dozens of times.. :-) no problems there at all :-)
"Consider how lucky you are that life has been good to you so far. Alternatively, if life hasn't been good to you so far
If it's pure science fiction, then why does the U.S. MILSTAR/NESP communication system have an operation mode for just such a scenario?
This is called "scintillation", and is very real.

When they interview many of the Katrina NOLA refugees, a common regret is that they've lost family pictures. At this point there is no reason not to start scanning paper-based photos in high-resolution. I've been pursuing a long term project of scanning documents, family photos, certificates and so on -- and making two sets of copies of the DVD archives. One set goes to a safe-deposit box and the other gets sent out of state to a relative in Ohio (I'm in Maryland). Each disk has a printed list of contents attached to it.
Apart from my wanting these images to survive, they are an important part of my children's and my extended family's legacy.

I have been thinking about encryption options for files on a USB drive for a slightly different reason. I want to keep finical info like tax returns, investment records, etc. on a USB drive for the reason that if my box does get compromised then the stuff that could REALLY f%&k me over will not be on it. The basic idea is there is data I want to store digitally, but I don't want it on a computer that is connected to the internet 24/7.
So I'm really naive about encryption options and would like my data to be readable on Linux, OS X, and Windows at minimum. What options do I have besides a password protected zipfile? Are password protected zipfiles encrypted using the password as the key?
How reliable are USB drives? How many backups should I make?
Think Deeply.
My ideal 'out' kit;
My personal records are scanned in high-res PDF format and kept on a jumpdrive. Identicals are kept with both of my parents on identical hardware, and my grandmother holds the originals. (This includes my birth certificate, my SSN card, my high school diploma, last 3 years of 1040 forms, my insurance policies, my driver's license, my EMS certification, and a few odd bills here and there for 'proof of residence'.)
I keep a backpack packed with a dry pair of pants, fresh socks, two t-shirts, a sweatshirt, a bright orange-and-yellow 'RESCUE ME' vest, emergency self-inflating flotation device (rated to 225 lbs), 4L of drinking water, 6 MREs, a space-warmer blanket, air-activated hand-warmers, a flashlight, batteries, sweedish-firesteel, 600$ cash, a rescue strobe light, a leatherman, a wide-band two-way radio and scanner, a GPS reciever, a universal hand-crank charger, a map, a compass, pencil, paper, an emergency contact card, and the aforementioned USB keychain.
It's not a huge bag, one just has to know how to pack. I do not live in the countryside by any means, but I travel through such areas often, and you never really know where you're going to end up if you need help quickly.
I also keep a proper EMS bag (affectionately known as the 'blue bag') in my trunk, as well as a large ammocan with more space blankets, MREs and fresh drinking water. The assumption is that I'm not alone in the car, and we have to create a shelter-in-place.

I managed to eacape from an East European country without anything, no passport, no PhD, DSc certificates or any other documents. Months later I managed to come to the US. After many unsuccsessful attempts to find an academic job, I eventually managed to get hired by a small university based only on the testimonies of three fellow American scientists who met me before and knew my work and a few photocopies of some of my publications.
Records are not always necessary, good, generous people can help you.
Flash can survive being submersed just fine as long as you dry it out before using it. But the USB flash drives seem likely to get mechanically messed up because of the way they stick out. I didn't get to use mine that long before it got pried the wrong direction by accident and went "crunch," so now I just use CF and SD cards. Of course, if you don't use it a lot, only often enough to keep the documents up-to-date, maybe it won't be a problem.
Transflash or SmartMedia would be sturdier. But SmartMedia is obsolete and transflash is so small that it's very easy to lose.
You could just store the docs on your cellphone and plan not to lose it, or store on a memory card which is in your cell phone. But then the memory will get used more and be more subject to wearing out.
iButtons are about the sturdiest format there is, and they have encrypted ones too, but they don't have enough memory for much data. There are also flash-based smart cards you could keep in your wallet. But neither of those is common enough - it's hard to find a reader for them, harder than finding a usb port anyway. Smartcards _should_ be standard equipment for securely storing all your passwords and personal info, but it hasn't caught on, mostly because of paranoia about "big brother" or "mark of the beast" or identity theft or some such.
Maybe you could pop open an SD card, fill the empty space with epoxy and put it back together. It would probably be more durable that way. Or, do the same with a USB drive. Or use the SD card by itself most of the time, and keep a compact new USB SD reader in your knapsack.
Yeah somebody should be manufacturing a really tiny usb key that has encrypted flash, implements some smart-card-like protocols for partitioning information with different keys, and sticks out of the port less than 1 cm, and is very sturdy. Having it stick out less would reduce the leverage when it gets bumped against something.
Let's start out with:
Don't forget to review the US Army Corps of Engineers.
You can google and wiki more on your own.
If the g'vt kept the data on you that google does you'd better believe you'd be calling it "doing evil"
EMP effects were observed at a distance of 1500 km during the Starfish Prime test blast. Quoting the linked article:
This was in 1962, so we're talking about vacuum tubes and electro-mechanical systems. Modern semiconductors would be significantly more sensitive to EMP effects.
It is entirely focused on records. This is the information age, right? So we need our personal information to survive, right? As I've already posted the information might well turn out to be important, and you should make sure you have it, but if Katrina taught anybody anything it's that papers don't insure your survival. You can't eat your papers (although when things get really, really sticky you might be able to trade them for food).
.money. If you don't, more gorp. When push comes to shove people will trade you nearly anthing for food. Money weighs less than gorp though. If you have your choice don't stay civilized. Head for the woods. Cities are a barren desert when it comes to survival. The woods have everything you need to survive (these days even including manufactured items, more's the pity). Cities often do not. Cities are also full people. Being full of people stretches resources so they don't have things in 'em anymore. People are also nasty sumbitches who will hit you over the head and take your precious personal information, encrypted or not (they don't find out how well you encrypted your information until after they have hit you on the head).
What you really need in that pack:
A good, sturdy pocket knife. Not a Swiss Army jobber. A single blade, like are sold to hunters. Metal, not ceramic.
A metal spoon.
Cheap chopsticks.
Do not, literally upon pain of death, use any other utensils than these to prepare or eat your food if you can at all avoid it. Make it a religion to keep them clean and sanitary.
Strike anywhere matches in a waterproof safe.
A firestarting piston. Use this before you resort to using your matches. Learn how to use it before you leave home.
A personal water filter.
A bottle of alcohol. 190 proof vodka is 190% better than the stuff from the drugstore. Make it yourself if you have to. Learn about cold distilling if you want to take the long, but easy way.
A few ounces of honey is nice to have along, but this is the most dangerous stuff in the pack. Think hard about it before including it. You can eat it if you have to, but that's not what it's here for.
Aspirin.
Antihistimines.
Any other drugs you personally need to stay alive. If you really need Prozac or Valium to stay alive, plan on dying.
A homemade soda can stove.
A mini roll of duct tape.
5 pounds of gorp. If tightly rationed this well feed you for a week.
An "Emergency Blanket."
Ziploc Baggies (These last two items are the only survival gear of note invented in the 20th century).
A camelback water resevior recently filled with known good water.
100 feet of parachute cord. Learn how to tie knots before you need to.
Wool cloth. Two shirtweight peices 45"X 72". One heavier weight 60"X108". These are your clothes, your hammok, your chair, your carryall, your. . .
Learn how to use them as such before you need to. Do not be tempted to substitute cotton for wool to save money. The savings could kill you. Not in a pleasant way either.
Two pair of wool socks.
Three yards of 36" wide cotton could come in hand as well. This is your hat, your belt, your shoulder bag, your sling, your . . .
A waterproof, windproof shell. Yes, even if you're in a tropical zone.
A pennywhistle. Yes, I'm dead serious about that one. Learn how to play it a bit before you leave home. Even better, also learn how to make a pennywhistle out of any tubular thing you can find, before you need to.
If you expect to stay "civilized". .
Two weeks with me showing you how to combine all this stuff with stuff you can find anywhere (like pebbles), especially in a disaster zone, otherwise you're just going to be in deep shit within an hour anyway.
Time with me is limited. Start poking around the internet for this information now. For God's sake, learn to take care of yourself. Any baby cockroach can do it. Your brain is bigger. Learn to use it for somthing other than tracking your stock portfolio.

Unplugging is a good first step, if that's all you can do. Strong EMP will induce currents in electronic circuitry stong enough to fry much solid state electronics.
Living in New Orleans has burned a few lessons into me.
First, make a list of things to take if you have to evacuate. I forgot several things when packing up at 3am the day before the storm hit.
Second, keeping a safety deposit box in the same area as your house is a bad idea. We have banks which have been closed for a month and will probably be closed for many more. People come in every day asking about when they can get it. People wanting to leave the country but can't get their passports, very bad news.
Third, keep a decent supply of water and canned food. Rotate the supplies to keep them fresh but always maintain one weeks worth of supplies. Figure at least one week before outside relief gets to you. Two weeks would be a safer bet. It's easier to do than you think. A water dispenser with 3 or 4 bottles should hold you over nicely and large cans of food from Chef Boyardee will make this very inexpensive. To use those cans, make sure you have a mechanical can opener on the assumption of no electricity. Keeping a 12 pack of Toilet Paper around doesn't hurt. If anyone asks why the large amount, simply say that you get it cheaper.Keeping some cash also doesn't hurt a bit. When the power is out, checks and debit/credit cards are worthless. Multiple things can happen outside of a nuclear war or hurricane which can force you to be self-sufficient for a week or two. Trust me, when the lights don't work, the police won't answer 911 calls and people are looting, you will be forever grateful you took a little time and money to be prepared.
Fourth, paranoia can be a good thing. My wife complained when I bought a generator and 40 gallons of gas at the start of hurricane season. She gave me even more grief when I bought canned goods and water we didn't need within the next week. She sat on the sofa while I boarded up my house like world war III was coming to New Orleans. She thanked me several times for doing all of the above when we had electricity, food, water and an unlooted house after the storm.
Personally, I send all of my files to both Gmail and Yahoo. I have seperate accounts set up just for those files. If a disaster befalls the US that takes out both of those companies and destroys my home computer on the other side of the country, losing computer files won't matter a bit, I'll be too busy trying to survive.
Why not just save your "important" data on a drive mounted in a removable IDE drive bay. If you ever need to take everything, you just shut down the machine and take the drive... Yes, this may be a little heavier than a USB flash drive... You could build a set of cron jobs (like I have) to back up your important directories to the removable drive on a nightly basis...
"Documents and Settings" for a Windoze box
"/var/mail" for Linux
User directories under Linux
Bookmarks, Mail Client directories (Thunderbird, Evolution, etc), IM directories (GAIM, Trillian, Google Talk, etc)
This would probably be preferable to say an external USB/Firewire drive, because it would be much faster for standard operations and would be connected until you took it with you...not to mention, there's more you can do for a damaged harddisk than a damaged USB flash drive...hard drives are sealed...most flash drives are not...there's a whole industry built on recovery of harddisks...not so on flash drives (not yet...it's probably coming)...
Or better yet, why not use one of the GMail Filesystem. This would certainly be more likely to survive...you wouldn't need to "grab" anything...all you would need is a machine with web access...keep something like 7-zip for Windows, GPG (or what ever you used to encrypt the data), and the GFS software for Windoze and Linux...you wouldn't really even need the archives, just a "draft" message with links to the files/projects. You could use another online filesystem and mirror the accounts (don't use software raid, just use 2 devices), so you could always recover the data if you lost access to one account.
But then again, what ever happened to the idea of keeping a safety deposit box in another city??? You can get to it once you are "safe"...not to mention that the authenticity of "scanned" copies of documents would be questioned because of Photoshop/Gimp...with a safety deposit box, you could have notarized, physical copies...Many of the things you list are things that you really don't need at home and generally wouldn't mind driving to get when/if the need arises (SSN, wills, Birth Certificates, Tax Returns, negatives of family photos, etc)...which would make a much more difficult situation easier for you (knowing that your important personal documents were safe)...who wants to worry if the only scan of their birth certificate was going to survive when they themselves are in danger...not me...
If you DO go with the USB Key idea, then don't trust any of the "built-in" security schemes and use your own encryption and buy 2 and use software RAID to mirror the drives. That way the data could be rebuilt if either one fails...you could each carry one of them as well...in case something happened to the other one...also beware of the pitfalls of flash memory (limited number of writes comes to mind right away)...
Any idea of saving hardware is moot if you're thinking of a flood in a major city (like NYC), because even waterproof hardware would be destroyed by all of the chemicals that would be floating in the water...
Don't forget to scan all your family photos and all the photos from your parents collections of you and your siblings. Scan high resolution like 600 DPI.
Scan examples of the work that you have done. Source code, schematics, written documentation, blueprints, photos, letters of recommendation. Include these with the family photos and financial info. Don't forget medical records (remember also childhood immunizations and disease records, ask your parents if you don't have them) and hi-res scans of any X-Ray photos and dental records if you have them.
Buy or borrow a DVD recorder and copy all your photos, along with high resolution scans of birth certificates, tax returns, property deeds, financial records, etc. onto many copys of DVD ROM of all this data. Encrypt only the sensitive financial data. Make a copy of your and your family member's finger prints. Be sure to encrypt these before writing them to the disk. Make recordings of your voice. Record your spouse. Record your kids. Shrink these recordings into MP3 and OGG files (high quality 256KBPS) and include them on the disk. Not sure what to say? Dictate a will. Make a list of all your possessions. Include serial numbers, descriptions, digital photos, and estimated value. X sweaters, Y pairs of underwear, ect.
When you've done all this stuff listed above, make many copies of the CD/DVD-ROM. DVD-ROM blanks and CD ROM blanks are very cheap now (about 50 cents or less) and they can hold a great deal of information and photos. Send a copy each to your parents and spouse's parents.
Keep a copy of this disk in your car. If you get hit with a big disaster and have to get away quickly, you most likely will not remember to gather this stuff or you may have forgotten where your 'life disk' is located.
I'm not sure if this applies to you but sooner or later it applies to most people. If you are 'illegal', no proper immigration documentation, no passport, expired visa, fugitive from computerized bench arrest warrants regardless of how long ago it was issued, or if you are at risk of arrest because of lifestyle (you sell weed for a living) or are a political activist in a dictatorship, you might consider creating a complete new and separate identity for yourself. And keep the paperwork for this identity on a CD-ROM, encrypted of course. Put a few soft-core porn pictures (be sure to use ones that are not illegal) unencrypted on the CD in case you are forced to display the contents of the CD to the police (resulting from a search at a traffic stop or a random police stop-and-frisk on the street). You may want to have this info on a 512K Flash Disk (or a 3.5 inch mini CD) that you can carry with you at all times. If you are undocumented or a fugitive, you may find that you have to escape without being able to go back to your home to get your papers, contacts, or alternate identity papers. In this case, having a flash disk with a complete new identity on it is a big help in maintaining your freedom.

I know you can rough it with leaves and stuff, but come on, you've got a ton of other stuff to worry about. Why add an abraded arse to it?
I would include some condoms (about 8), a few packs of cigarettes (even if you don't smoke, they are fantastic for bartering with nicotine addicts, and an emergency contraception kit of a few birth-control pills, like a unit of Plan B (an actual American product sold for post-coital contraception.) If you are a male, this seems absurd. But if you meet women in an emergency situation who do need this (inquire very discretely), they will be your friends and allies to their dying day.
If you can find one, a hand-crank flashlight with super-bright white LED bulbs and a hand-crank radio would be good too. An unusual item that might be useful would be a software program for the USB keychain that has a 10000-word English/Spanish dictionary/phrase book. A PDF file of wild edible plants (with photos and drawings) would be more useful than a cannibal cookbook.
Corsair has a rubberized water resistent shock-resistent flash drive available. I have one and found that it is quite durable: http://www.corsair.com/
As for encryption, check-out this open source project which offers an excellent encryption solution for Flash drives:

I have heard that you can put some documents in the freezer, as it will be mostly waterproof when the FD floods your house and stands a decent chance at being fireproof as well.
We bought a little fireproof waterproof safe for like $50.
I think the topic of this post was mostly for big chemical, bio, or nucular attack on NYC or DC. What would you take? How prepared would you be to never come back to your house?
BTW, Foxfire books are awesome if you don't have the series already. Great stuff with good detail on everything from building a log cabin to making moonshine to making a violin.
