Secure Data Storage... On Your Fingernails
opticsorg writes "Secure optical data storage could soon literally be at your fingertips thanks to work being carried out in Japan. Yoshio Hayasaki and his colleagues have discovered that data can be written into a human fingernail by irradiating it with femtosecond laser pulses. Capacities are said to be up to 5 mega bits and the stored data lasts for 6 months - the length of time it takes a fingernail to be completely replaced."
Ironic that this comes up at the same time as a poll about "least favourite finger" - now they can all be useful again.
I say we take off and nuke it from orbit. It's the only way to be sure...

Secure optical data storage could soon literally be at your fingertips thanks to work being carried out in Japan. Yoshio Hayasaki and his colleagues have discovered that data can be written into a human fingernail by irradiating it with femtosecond laser pulses. Capacities are said to be up to 5 mega bits and the stored data lasts for 6 months - the length of time it takes a fingernail to be completely replaced. (Optics Express 13 4560)
Fingernail storage
"I don't like carrying around a large number of cards, money and papers," Hayasaki from Tokushima University told Optics.org. "I think that a key application will be personal authentication. Data stored in a fingernail can be used with biometrics, such as fingerprint authentication and intravenous authentication of the finger."
The team's approach is simple: use a femtosecond laser system to write the data into the nail and a fluorescence microscope to read it out. The key to reading the data out is that the nail's fluorescence increases at the point irradiated by the femtosecond pulses.
Initial experiments were carried out on a small piece of human fingernail measuring 2 x 2 x 0.4 mm3. The writing system comprises a Ti:Sapphire oscillator and Ti: Sapphire amplifier. Pulses of less than 100 fs at 800 nm are then passed through a microscope and focused to three set depths (40, 60 and 80 microns) using an objective lens.
Each "bit" of information has a diameter of 3.1 microns and is written by a single femtosecond pulse. A motorised stage moves the nail to create a bit spacing of 5 microns across the nail and a depth of 20 microns between recording layers.
An optical microscope containing a filtered xenon arc lamp excites the fluorescence and reads out the data stored at the various depths. "We regulate the focus with the movement of the microscope objective," explained Hayasaki. "The distance between the planes is set to prevent cross-talk between data stored at different depths."
Hayasaki adds that the same fluorescence signal is seen 172 days after recording.
Although the initial experiments have concentrated on small pieces of nail, the team is now developing a system that can write data to a fingernail which is still attached to a finger. "We will develop a femtosecond laser processing system that can record the data at the desired points with compensation for the movement of a finger," said Hayasaki.

i admit i didn't read the article, but what about when the nail is partially being replaced?
and the stored data lasts for 6 months - the length of time it takes a fingernail to be completely replaced."
So wouldn't half the data be lost in 3 months?
And on which finger would you store all your porn?

There is a theory that says that it is possible to store any amount of data on a finely-machined metal rod.
First, take any data (for example the text to Moby Dick) and turn each character into a digit. A=01, B=02, etc. Then string them all together into one long stream of digits. Once the text is translated into this long number, add a decimal to the front of the string.
Now you have a fractional number. 0.0301...
Measure out *exactly* that length in relation to the length of the metal rod and machine a line at that offset. Voila, you've stored the entire text on a metal rod.

Now that's what I call "digital" storage! The article says that they're currently only working with fingernail trimmings. They have yet to work on fingernails which are "attached to a finger," raising issues due to natural movements.

This isn't secure at all... now we're gonna have people looking for our nail clipping in the garbage and stealing pin numbers right off of them.
Honestly though, the only thing I can picture this being good for is for stealing data without being noticed.
I have visions of data thieves, coming after me with pliers!
What I think is the most important question that we must ask is : Is this technology "hit resistent"? I mean, is it like a CD/DVD (a scratch, data is lost)? If they could write the data deeper into the nail, maybe it could withstand a couple of stratch and hits, wich is daily life. If it can't I cannot see the utility of this.

I'd have to say that the trick was them actually etching the nail and reading it back. Stil, I doubt this was done on a nail attached to someone, and until that can be done, it's useless. Seriously, you're going to need to bolt down a hand to get 5 micron resolution. I just don't really see it happeneing, unless someone has any ideas how you can immobalize a finger/hand/arm. A micron is darn small when it comes to humans, and 50 of them doesn't help much either. 5 Megabytes, is about 42 million bits by my count.
I don't know how many shots it takes to burn the hole, but most of these lasers run on a 1KHz rep rate. It's not too hard to block the beams at that rate, so that's not a problem. Still, think about how long that would take to write if you only needed 1 shot per bit (unlikely). Not to mention the time it takes to move the fingernail.

Well, the data loss would be constant because even if the nail is not completely replaced, a part will still be missing. Maybe using toe's nails would be a better idea, they are a lot larger and grow much slower than hand nails. But then again, i find this thing to be pretty silly.
Just last night I saw the episode of TNG where a Klingon was stealing Star Fleet records and encoding them into amino acids, which are injected into the blood stream to smuggle data off the ship. They thought it was amazing that the human body was used as the conduit of information. If only the Klingons had this technology, perhaps they would not have been caught.

How many "bytes" in a fingernail?

I hereby post this to a public board to prevent money-grubbing corporate types from patenting this idea and preventing others from producing it.
I think I've come up with the perfect use for fingernail storage. Substitute it for passcodes, door codes and biometrics. This has all the advantages of biometrics and fewer drawbacks. Here's how it works:
Imprint a code onto a fingernail. At a secure door, you have a fingernail scanner. Insert finger. Code is read off the finger and processed much like a door code or pass card. Door is opened. After a period of time, your code expires or if it gets stolen (logically or physically [ouch!]), disable the old code and imprint a new code onto another fingernail. The old fingernail grows out and can be reused.
Unless it is physically stolen, in which case you have 9 more! Okay, some drawbacks of biometrics are still there.
But why is the rum gone?
This would be great for IDs and checks that you have to renew occasionally.
If you don't check in to renew your visa on time then leaving and re-entering the country becomes much more difficult. If you don't get re-etched every time you visit your parole officer it is obvious when you are next checked.
Put the etching closer to the tip for shorter periods of time.
Use it for "buy ten sandwiches, get the next free!" promotions.
Etch a new credit card number on every month - you know if someone physically stole the nail, and if they only got the number then it won't be valid after a few weeks if you don't notice right away.
Could be coupled with fingerprint scanners. The fingerprint would not be stored in a big DB - it's encrypted on your fingernail. The scanner checks that the info on the finger and the print match so it's more difficult for someone to copy - they need both the fingerprint and the numbers, and the fingerprint never leaves the scanner. No need to worry about some corporation "losing" your fingerprint like they "lose" other personally identifiable information - they never store it in the first place.
Then add a PIN and you've got a reasonably secure system - something you are, you have, and you know. Don't want it anymore? A quick swipe of the nail file and it's all gone.

I remember going to Hawaii back in the summer when Jurasic Park came out and we were warned about wearing expensive rings on the streets, something about street gangs cutting fingers off to get the ring easily. If that was true then the new question arrises which is: which will be more valuable, the ring or the fingernail?
On a simular note, I hope the biometric people don't use the fingerprint that is on the same finger as the nail or it would be easy to compromise.

Hello
I would just like to inform you of an error i have noticed in your post! it seems you believe efax to be spammers. This is not true at all!!
Efax is a professional company who sells fax numbers to people. your new personal fax number is then delivered to your email address of your choice. so say i need to recieve a fax. i do not have a fax machine or do not want to pay any sort of long distance charges. i can just have the person faxing (transmitter) fax to this efax 1800 number and it will go directly to my email box! Efax is providing quality service that my business uses to recieve faxes from customers. basically when a customer wants to fax in an order it comes right to the PC or script on a webpage isntead of a fax machine that would have to be pain stakingly typed in! As the CEO of a large fortune 500 company, i would say that efax has increased profits by NO LESS THAN 10000%! efax is providing what everyone needs but no one knew how to ask for!
as you can see efax are not at all spammers and therefor i believe your sig to be in error.
Does this mean that we will need an alternative method for disposing our fingernails, like we do receipts and old paperwork? Trash digging for fingernail clippings is an all new low in data/identify theft. Also very interesting, there's less anonymity when disposing of the fingernail clippings... Better make sure your fingernails are encrypted.
Simple:
Data you wrote there six months ago is destroyed. Data wrote more recently remains unaffected.I'd think that if you were interested in any kind of long-term storage, the parts of the fingernail that were written to would be close to the nail bed.
Unless you chew your fingers down to the first knuckle, thereby eliminating all traces of fingernail, biting your fingernails shouldn't affect anything recent.
Now, for women, colored nail polish is probably the greatest threat. And manicures are probably number two, what with the sanding and polishing of the nail surface. But depending on the depth the data is written, maybe it would survive a manicure...
they say it takes 6 months for the fingernail to be completely replaced? am i just a freak with fast growing fingernails? a while ago, i cut a little notch in the base of my thumbnail, and i'll be damned if it took more than two months to grow all the way to the edge...
Engraving a person's ID or even his entire medical chart can help prevent mistaken identity later on.

Rather, a piece of nail that had been trimmed off and subsequently polished before being written was used. They hadn't demonstrated this with a growing nail attached to a living person. Second, they were able to write three different layers at different depths in the nail, which I thought was very cool. Anyway, it was very interesting work.

What?
Seems like if you can do this with the keratin of a fingernail, you could probably also inscribe information on a single hair. This raises all kinds of ideas for future spy novels -- data smugglers carrying nothing visible, but the hair on their scalp holds all the source code for Microsoft's entire product line....
We'll just use some parity bits. It works for CDs.
...the finger nails YOU.
Note the media size they're talking about: 2mm square by 0.4mm thick. That's teeny. So for everyone fretting about biting your nails and losing your data, each finger could probably contain multiple backups of its own data (or better yet, copies of all of the other fingers' data).
Mittens.
Will identity theives go dumpster diving for clipped fingernails? Probably.
Yea that's all I need know is to have some wackjob cut off my finger so he can use my identity to break into some top secret area and use what's their to destroy the world!
Remember, try to keep away from emotional knee-jerk reactions. They had plenty of those when interracial marriages was allowed or slavery was abolished.
"Creepy" is not a rational word.
Transcend Humanity. Please.
If you are a spy and you are caught by the enemy, should you bite off your nails or wait for your captors to take care of that for you?
Who is going to develop the data reader that is installed in your nostril?

Enjoy!
A good reason to leave my clippings lying around!!
RAID 5.
Stripe checksum data across all 5/10 fingers, for when you lose some.
Ohh! I broke a nail!
There: Something at a specific location.
Their: Owned by someone.

FINGERNAIL OPTICAL DATA STORAGE:
Pros:
5 megabits of data
Lasts 6 months
Information can be encoded
Cons:
I can't scratch at my fingernails
Probably prevents use of nail polish
Requires laser to write/read (expensive)
Where am I going to find laser?
STRING AROUND FINGER:
Pros:
Does not require lasers
String is cheap
Securely encoded using memory encryption
Cons:
I have to have this string around my finger
I don't like having string around my finger
Requires string to write
Where I am going to find string?
Requires memory to read
Encodes very little information
Lasts only as long as I keep unsightly string tied around my finger
WRITING ON MY HAND:
Pros:
Does not need a laser
I usually have a pen with me
Requires no special device to read
Cons:
Can only store 5 megabits with very very small handwriting
My handwriting is terrible
Washes off
Not secure: Other people can read it
WINNER (until I get a laser):
Writing on Hand

YOU ARE SAYING IMPUDENCE TO ME! THAT IS IMPUDENCE!
Land on your hand awkwardly, lose you presentation.
How does this data hold up in the shower?
Gives it a whole new meaning...

Okay, since flavored gelatin dessert items are, essentially, the same suff as plain old fingernails (plus some flavoring), does that mean that this system could be applied to, say, a Jell-o cup? Since you have a larger volume, you could potentially store multiple layers of data.
Keep in a cool, dry place out of reach of children. And if anyone tries to confiscate your data, just eat it.
Alternatively, if the "jiggly drive" isn't stable, you could increase the gelatin saturation to a more solid point, and encase the whole thing in a hard, transparent, sealed shell (like acrylic). Oh, and leave out the sugar and flavoring.

One possible application would be to etch the parents names on a newborns finger or toe nails just after birth. Could be a failsafe to keep from having a mixup.
No matter where you go, there you are.
I suppose the data last avg. 3 months, after which fresh unfragmented storage space is available
I'm still trying to figure out what people mean by 'social skills' here.
"Digital Storage".
As in digits.
Think about it.

I can see the conversations now;
"Black Nail polish, you must work in a high security company"
"No, I went to a Goth club last night and forgot to take it off."
Reminds me of a Gibson's Iduro, Blackwell who had been a Toe Cutter I will let you look it up.

Let's face it, it's only a matter o' time before the down-and-out are forced to rent out their fingernails to greedy corporations for off-site storage. Think I kid? You can already buy advertising space on your fingerprints.
Does it support RAID V? =)
they are going to kill me but the government already stores data in your hair and fingernails! They know everything you've said or thought about for more than a few seconds. This is why I pulled all of mine off. toenails too...but they got you with your teeth...you have to eat.
How many cameras see your fingernails each day?
People will find a way of taking high enough resolution pictures to read the data off your thumbnail without you ever knowing. Forgive me if I decide to carry around my CD-RW (in its case) instead.
What if my sister likes to wear nail polish?
Will she lose the data she stored on her thumb the previous day?
I don't know if the status quo has changed since then, but the last time femptosecond lasers were mentioned on slashdot (in an article about storing a TByte in a 1cm^3 cube of glass), a researcher confirmed that they took up most of a room sizewise.
You aren't going to see this in use anytime soon, if ever.
Even people that believe in pre-destiny look both ways before crossing the street.

Now you can store your Nine Inch Nails MP3s on your nine inch nails... =o
Oh! I just cut it off this morning!

So, they've developed a storage medium that works on fingernails *not attached* to a finger... If this is going to be used for authentication purposes, I for one hope the final implementation of readers includes measures to ensure the finger is currently alive. Surely it wouldn't be too hard to include sensors to monitor for a pulse and warmth. Don't those dodgy love tester machines work off a similar principle?
cause I have a bad habit of biting my nails.
Whe knew the day would come when girls no longer hold monopoly for moaning about broken nails...
Unless you chew your fingers down to the first knuckle
Guess there's no reason to worry about anyone recovering your data.
This sig isn't original enough, it's time to come up with something witty...
Here's a preview of what it will look like!

Or perhaps anyone who's been in a Best Buy, Circuit City, OfficeMax, Staples, etc. in the past 2 or 3 years?
I see even classic Slashdot is now pretty much unusable on dial up anymore.
