Random thought related to the php jpg.

Is there anything similar to the QRCode square barcode that could be generated that wasn't quite so obvious as to being an image branded with writing on?

UPDATE - inject user details into your images on the fly

In addition to injecting your user details on the fly into a mpg movie, you can now do the same with your jpegs...

Save that image and view the exif info (with whatever app you use to read exif info)...

Your user details are stored in the Description tag

OK read a lot more and can offer this.

Borked's solution would work if the only place to get porn was on the Internet. It won't work for most because DVDs can be ripped, unless they invented a blocking program that's 100% secure. Even then what about all the DVDs that don't have it?

So pirating can continue. The pirate sites what ever their format will not stop and let all their traffic disappear, they will make sure there's full length DVD rips for their surfers.

Plus 75% or more of the sites on the Internet have porn that's fairly well indistinguishable form 100s of other sites. So if you lock down your site of a teen getting fucked on a sofa, the surfer has loads of other options to get free porn just like it.

Might work for Astral-blue.com and if Borked would like to contact me and give me a price we will consider it.

Isn't all of that very expensive to implement? How much does it add to the members cost? And when net neutrality goes bye-bye (probably 2011), how much more are you going to have to pay to keep that stream running at a bearable level?

on the fly qr code generation... I already brought that up ages ago, but could be adapted to this

https://gfy.com/showthread.php?t=910434

as to anything similar - highly doubt it as qrcodes are used all over the place now by manufacturers... simple and effective

He never claimed to be able to protect your magazine shoots, or your over the counter DVD's that isn't what this board, or industry is about. Related? Sure, our problem? No.

He's showing WEBMASTERS how to stop their content from being shared that is downloaded of their sites.

Paul - yes I did put up the disclaimer that this was purely for online content. Protecting DVDs is a never ending battle with even the new BlueRay protection recently being cracked

If you want to protect DVDs I'd suggest asking the MPAA for help, since they have tried endlessly...

Implementing these things I've set out here are custom to each person's server setup, since it's adding a layer on to how images/movies are displayed and downloaded/streamed. So it would be near-on impossible to package things up for an all-in-one install package.

If you'd like them implementing on your site, drop me a line by email so we can discuss further. It shouldn't be hard or long to implement these things for a single site.

Wow, that is SWEET! Kinda freaked me out when I saw my details in the exif info!

A 10 minute vid at 30 frames-per second equals 18,000 frames. If the codes are inserted randomly, that is a whole of frame-by-frame checking. Make the code semi-transparent, it makes it even harder to spot. Or see the comment below.

1. You can do color shifting to hide numbers, in an image. Pick some square areas, and bump the colors in that area a bit. Basically be almost invisable to the naked eye.
For a "0" = current color + 4*10
For a "1" = current color + 4*1
For a "2" = current color + 4*2
For a "3" = current color + 4*3
...
For a "8" = current color + 4*8
For a "9" = current color + 4*9
Then just do a "mask" comparison between the original and the encoded to reverse the calculation.

This is fine for transmitting hidden data between receiving parties, but I think it has its limitations, especially in video, for trying to track a file. Simply because any type of compression algorithm will result in the hidden message being lost, so transcoding a video from say mpeg to flv will kill the information. I would say inserting random frames is far better since they will survive transcoding and nobody is going to search 1000s of frames for 1-10 "randomly" injected tracking frames.

Random because to the end user it's random, the to producer they could inject constantly eg every (#frames / 10 + 15) frames - random to the end user, the producer knows exactly where to look each time though.

A very selective reply. I did address your point and it seems I will have to again.

Our problem? YES. Because so long as there is pirated content being given away for free surfers will keep being surfers instead of members. They don't care if it's online or offline content, it's all content to them.

If you have something like Robbie has or I have with astral-blue.com there is a point to protecting it. If you have the same generic content as I have on paulmarkhamteens.com it's not.

Andy, I dropped you a line.

I'm a bit lost with that, maybe it's just because it's monday morning.

I'll read it again later and hopefully won't need it translating into idiot

Well, so is applying steganography. However, noone said you had to make the Description tag so obvious... I guess few people would think of stripping it out if all it said was

Tori Black #530419

where the number is of course a db entry ID containing the info

The color shift comment was targeted at images only to make it invisible for the uploader/surfer to actually see the info.

Also using 99% transparent text is basically invisible to the naked eye.

But, a program can compare the before image to the after image and easily tell the difference. If the surfer doesn't have the exact "before" image they can't make the comparison.

ottopottomouse:
The color-shift would be done by changing the color over small rectangles in different parts of the image. Again the visual change is so small(aprox 0.001%) that only a computer comparing before & after images could actually "see" it.

No, what I meant was, if that image then went through a transformation (lets say linux "mogrify -sharpen 10" to sharpen up the image (or reverse "-blur") or make the image larger, smaller, then the way to extract the information to find out who is the pirate is lost, since jpeg is not lossless.

Unless I'm completely missing your point.

For example, if encoding images to something else wasn't a problem - ie someone stole your image and simply uploaded it elsewhere), then all you'd have to do is inject in a random pixel somewhere on the fly and calculate a visual hash of the image (and store it). The next user to view the image would have a different visual hash since the pixels are inserted randomly (more pixels added and higher res the pic, the more unique the hash). If you found your image somewhere else, you calculate its visual hash and then find out who pirated it.

eg - visual hash of an image (using multiple cryptographic keys):

Which tells me that while Size64 can compute far more hashes per second, it's chance of being non-random is quite high, so let's pick ED2K which is really not bad, processing 239MB haseed bytes per second.

So in that case, a script could easily go and download images from the internet from known problem sources and at ~100KB/jpeg image, it would search ~2000 images per second to find if any of them came from me, and if so who was the user pirating it

As an automation technique, visual hashing is definitely the way, and while algorithms exist to catch lossiness in recompression (as well as videos), it's frikken complicated maths!

borked · 10-04-2010, 02:00 PM

Sorry for the technical replies - it's good to keep technical stuff out of the thread to not complicate things...

However, I'd love to discuss technical stuff over email or IM...

For those of you actually reading this thread - it means you are actually interested in piracy prevention and proper detection....

The "real world" is light years ahead on all this as visual hashing is a massive research area (especially in videos given transcoding, youtube, copyright etc)

For one example (warning scientific paper, but well written and good visuals!) - see this PDF manuscript. There are hundreds more like it (but more mathematically detailed!)

The real world is moving forward a lot, which is why large companies can easily send take down notices to google because things are automated.

When it's so easy for some to send out mass emails to end-users of pirated content, why the need for all this piracy prevention?

I really do find it extremely amazing that there has been only one person to date that has actually contacted me to discuss wanting to implement things discussed in this thread on their sites. (4 days on the front page is like 8 years in real human terms)

If piracy is such a major problem in this industry, I only see a handful of people interacting in a serious thread that is highlighting how to combat it

Now this is getting interesting. I didn't like the branding each stream with a username and IP as I thought it was an ugly idea, and branding each customer as a thief. In stores, they remove the security tag on purchase.

However, this hashed pixel idea is brilliant.

I'm a magician as a hobby, and have several magic content makers that would love this technology/idea Borked.

I assume you are OK with mainstream work and I can tell them about your ideas?

Thanks

Branding videos with username IP was just an idea, but yes visual hashing is where the mass screening detection lies.

I have no idea what you have as an idea, but go ahead!

I am actively looking for a way of protecting the content on my sites. I am pretty attracted to the idea of a non-downloadable, anti-leech streaming system like the way Adobe and some other companies are boasting.

I called my billing company (ccBill) and they are promoting metrixstream. I spoke to them and their monthly licensing fee is pretty steep.

I am open to all suggestions that will slow down these file sharing maggots who rip off material for a measly membership fee and post my entire site on 10 different forums.

I really don't want to piss off my members, but more importantly, I just want a big deterrent to file sharing.

Any suggestions would be appreciated, and I am open to spending money on this, if it's a good service.

Hoping for some good help!

If you read further into teh thread, there is a way to do this on the fly, without the overhead of re-encoding.

You can produce a say 5 second roll at the start of the movie that says, "this movie was prepared for <username> <IP> on <data>. Copyright <your company> All rights protected. Do not pirate this movie.

That would scare a big bunch away from uploading it. For those that know how to remove frames, you would also inject that into the movie "randomly", injected as a single frame and the end user will never see it.

It's not the same as digital fingerprinting, but it's a good way of tagging the content.

you mean like the injection of user details/identification data as in post 76?

the data in the example is in a single frame at exactly half way into the movie.

an example of identifying the user in both preroll and injected somewhere in the movie

download
http://borkedcoder.com/movie_injecto...er=borkedcoder

the identifying data (given as example) is injected at the start of the movie and at exactly mid-point (search frame by frame at 8 secs, just where the boy starts walking) and at the end

cropped tight and a spherise filter applied...

anyone with any false positives? something I'm worried about is a very similar scene close up but from 2 very different movies...

btw, I've added a timer to the image comparing (doesn't include upload speed)

borked · 10-08-2010, 07:18 AM

I've added the confidence level whenever the images are flagged as pirated.

It was set to anything > 70%, flag as pirated - your images were 72%.

75% is very good at not letting through false positives through, but with the problem of letting some false negatives through.

It is currently set to 73% or greater to be flagged.

Would still get flagged even by raising the bar as the images are 76% similar....

The more "noise" in the image, the better.

A big full-frame close up of a pussy and well, one pussy looks like another, so false positive rate is higher...

Too slow unfortunately. To make it practical, it should do at least a billion comparisons/hour.

Nearly everything I have tried doing has been with an aim of keeping the image as close to the original as possible and get it to pass as NO PIRATE.

Just think that to make your comparison test as good as possible I need to to be trying to think of a way I could get a whole photoset to pass while still having it acceptable to the human eye.

Screen capturing video, at least in my experience with using Camtasia, loses a bit of quality (especially in audio, and the videos jump a bit depending on the PC you're using to capture it with). The other aspect is that the user has to actually sit there for the entire feed to rip it -- for a lot of people, that's too much work....and not worth it.

Paul Markham Too old to care Industry Role: Join Date: Jun 2001 Location: On the sofa, watching TV or doing my jigsaws. Posts: 52,943	OK read a lot more and can offer this. Borked's solution would work if the only place to get porn was on the Internet. It won't work for most because DVDs can be ripped, unless they invented a blocking program that's 100% secure. Even then what about all the DVDs that don't have it? So pirating can continue. The pirate sites what ever their format will not stop and let all their traffic disappear, they will make sure there's full length DVD rips for their surfers. Plus 75% or more of the sites on the Internet have porn that's fairly well indistinguishable form 100s of other sites. So if you lock down your site of a teen getting fucked on a sofa, the surfer has loads of other options to get free porn just like it. Might work for Astral-blue.com and if Borked would like to contact me and give me a price we will consider it. __________________ Blowout deal. 880 videos, 2,400 image sets, plus many RAW videos. $500.
