Who said anything about the article? I'm pointing at the cowardly retard above.
As for the article... wouldn't bother with it. Either study the study itself or don't bother commenting on the topic at all. And I don't have the time for that right now only so I could argue with idiots who can't add or bother to analyze the study.
For fake dots to work, you'd need to "jam" the dot-code by adding dots to the message. Doing that would require calibration for every single printer AND probably a special driver (or a customizable one) for every single printer.
And it would only work if steganographic dots are NOT randomly distributed OR they are distributed in a very predictable pseudo-random fashion. Still... Yellow dots are just one way of including steganographic data in printouts.
One solution conveys data using blocks of output pixel shapes [3]. Some techniques employ a watermark to convey visual information [4][5]. One such idea uses two halftoned versions of the same image that must be overlaid to reveal the hidden bitonal watermark; the complementary halftones are called "conjugate pairs" [6][7]. Dispersed-dot dithering approaches also hide data by manipulating image edges [8], or by toggling pairs of pixels [9]. At Purdue, Allebach has pursued the policy of not disturbing the data and instead has focused on embedding data in sub-pixel offsets available in some electrophotographic printers; he calls this the "printer mechanism" in his feasibility studies [10]. Clustered-dot halftones have been used to carry information by creating asymmetric shapes in the clusters, such as ovals [11], and manipulating shape orientation to encode a bit. Limited information can be embedded in clustered-dot screens by altering their phase and frequency [12]. For recovering individual ink patterns from color clustered-dot printed halftones, a solution for separating the scan of such halftones is reported [13]. Anoto [14] covers an entire page with dots of the same size and shape where every dot is shifted from a nominal position as a form of encoding, but is not in any way used to halftone an image or encode an arbitrary payload.
Because of this I have to wonder about the utility of these color printer watermarks. They may have worked in a handful of cases but once people figure this out then it's trivial to circumvent and it becomes worthless and expensive.
Worthless? Expensive? To whom?
Watermarking is done by the manufacturer as a part of printer's firmware. The cost of writing it is long amortized. While its implementation is currently costing about as much as a single copy/paste would. I.e. There is no cost. There is also no cost of record keeping as all you need to know is printed right there in the watermark.
As for circumvention... It's like saying there's no point in collecting fingerprints because there are such things as gloves and cloth rags to wipe the prints away.
BTW, firearms records are not there for "tracking criminals". They are there for tracking GUNS and people who buy and sell them, possibly illegally. Which, just like with printers, narrows down the pool of suspects from EVERYONE - to just the people who had access. In the much talked about Reality Leigh Winner case, the pool of possible suspects was immediately narrowed down to only 6 and she was arrested in a matter of weeks... from the leaks.
Ah yes... a world where we all live in medieval towns turned lake-resorts with no more than 5-6000 inhabitants. With all the modern and future technologies and standards of living still available. That would be quite pleasing.
I think that's basically how they live on Star Trek. Speaking of communism and all that... All we need is a post-scarcity economy with matter-replicators and warp-capable spaceships.
They lie about everything else, so you probably wouldn't get a true answer.
Paranoid schizophrenic spotted. Proceed with caution. He might try to push further conspiracy theories to you or force you to wear tinfoil on your head.
When informed that we intended to go ahead with this story, the NSA requested a number of redactions. The Intercept agreed to some of the redaction requests after determining that the disclosure of that material was not clearly in the public interest.
They raised her to become a person who'd, though only 9 or 10 when 9.11. happened, pick up Pashto, Farsi and Dari languages and join US Air Force as a linguist, where she served for 6 years. http://edition.cnn.com/2017/06...
Not to mention the whole thing where they raised her to speak out about issues of public interest. Such as evidence of attacks on the USA by a foreign government, while said attacks are denied by both the said foreign government - and the current USA administration which has landed the job in part thanks to said attacks. At the expense of own liberty, job, future...
Some people really take that oath thing about "support and defend the Constitution and laws of the United States of America against all enemies, foreign and domestic" seriously.
We can't let terrorists win! It's corporations who must be the leaders in civilian deaths caused by crashed planes! Not a bunch of religious fanatics armed with box cutters.
Just because the source was a cheap camera with no watermarks doesn't mean companies couldn't find them.
Find who? Person who made the recording? How? Using magic? Even should their crystal ball or palantir or whatever work - how would they prove that said person was responsible for the distribution of video? Even if it came from an IP registered to them - IP is NOT a personal designator.
With the scheme for paying 50$ to watch at home you literally have to identify yourself with ID and credit card each time. Slap a watermark containing encoded ID and last 4 digits of the CC, and if a movie containing those appears online - fines and lawsuits may commence.
Existing distribution contracts and clauses. If they have lawyers I'm sure they've included various protections for themselves in those contracts they've made with movies studios. And vice versa. Just like movie studios can't just switch to a new theater chain and leave the ones they've signed contracts with to dry - neither can theater chains simply dump one studio for another without paying penalties.
Its like having a tax on cars to assuage buggy whip makers that it will all be ok.
No. It's like making a contract with businesses who already have mutually obligating contracts with each other. THIS is the buggy whip/car tax.
Except now they could slap people who are torrenting their movies with fines and lawsuits literally within minutes of the video appearing online. The stream could be chock-full of watermarks and hidden data which would identify the account to which that video was streamed.
What they may be powerless against is private sharing networks which would allow people to stream a recording from a camera to their friends. Sorta like card sharing, minus the cards. Still, they'd probably catch a bunch of people who are idiots or have idiot friends and whose camera streams would end up online.
It would just drain some of your fat. You know... that biological battery technology used by all animals bigger than a bacteria. Also, besides being used to reduce fat by the slimmest of margins (Getit?!) it would probably be there to help diagnose various medical issues - perhaps even repair some of them.
Would that extend people's lives? Remains to be seen. There's always a chance that recording oneself while licking an electric socket might become the new craze as people keep giving up smoking more and more - eliminating any life extending benefits of medical nano-machines.
i.e. how to cooperate and even more accept the leadership of someone who does NOT share your point of view totally, would definitely be an interesting concept.
Also, they did the "particular point of view, your moral code, your history and your beliefs" with Voyager. Half of the crew were Maquis. SPOILER: They adapted to the more "by the book" Starfleet point of view, which proved more beneficial to their survival than the alternative approach. Still, some rules were broken.

Anyway, what I hated about this trailer is the lead character's ridiculous eyelashes. What does an eyelash curler look like centuries in the future?
It's a genetic trait left over from Max Factor - L'Oreal wars of the late 21st century.
Why not include a character who looks Chinese but was raised Norse?
Said character could be from a binary star system. And he or she could have a representation of Thor's hammer in his/her quarters, which could be a running gag in the show, with said character often threatening to "Grab Thor's hammer and..."

Black and white is a mode of the driver.
Steganographic dots are included on the firmware layer.
Besides that... grayscale or even pure black and white are no protection from steganography.
Stegatone encodes about 2k bytes/square inch.

Umm... "As we know it"... both parties don't look anything like what they looked pre-Nixon.

May may in May but she can't now it's June?
Yeah, but what if you replaced everything with stick figures?
Shark in Jaws could be just a single triangle. Hell... make that just two lines...
Someone get me Spielberg on the line!
I have an idea for a very low budget movie! It'll make back on its investments thousand-fold... million-fold!
