@@jakubsebek 50 years ago, the K-202 was considered top end computing power. It was sold at about 5000$, which was considered an amazing price. The most powerful variant had 144KB of RAM. It is so minuscule you couldn't even 2 or 3 pictures in RAM unless the are heavily compressed or in 8 bit, in other words of horrible quality. The lower quality of images which could be processed with such a weak computer would never be enough to perform this kind of difficult computation performed with the technology in this video (which according to the video maker can take a few minutes on a modern device). If a desktop computer from modern era can take minutes to do it, with even modern smartphones having 8GB of RAM and 4, 8 or even more very fast cores, computers 50 years ago would stand a chance. The K-202 had a million operations/seconds compared to the 3588.87 G operations/seconds
@@csharpcoffee this isn't a "difficult computation" lol, I was talking about a theoretical computation requirement, which is extremely low for this simple algorithm, your comment is worthless and completely missing the point, you know this, get a life
It probably doesn't, since the low resolution pixelation is trivial to compress, and any artifacts would be easily detectable and cleaned up (even by hand in ms paint)
I'VE LITERALLY ALWAYS THOUGHT ABOUT THIS WHEN RUclipsRS BLUR FACES OR TEXT. At least I thought about this idea being plausible if the blurred or pixelated image is moving, which means there will be multiple ways to pixelate a secret image. And since you can distinguish a blurred text saying Hello and a blurred text saying Pizza, there must be a tool that could decipher it.
Never really understood the point behind censoring it that way in the first place. Same when there are people being censored etc. you can tell what they look like with your own eyes and I wonder what a program like this could do
Depends. It obviously looks much better than just putting black bars or something over things and if done right, it still shouldn't be reversible. My guess is that this doesn't actually work on stuff censored by proper censoring software which blurs randomly. Blurring deterministically is obviously stupid. I'm sure there is software out there that does this but most proper tools probably do it right. And in any case, you still need to find out which exact algorithm was used and find a close enough font and spacing for comparison. The video clearly shows that it didn't work for anything but the provided examples which are obviously a terrible way to test. And text is obviously an incredibly easy case for this, especially with surrounding text giving you the font. It's an entirely different matter for images of people or similar.
not quite. the ai does not actually know anything . its just gussing things . kinda like how you imagine an HD version of any picture. that sort of thing would be useless in most cases.
Seems like it could be thrown off by fonts... also if it's looking up character combinations, why does the result look like it was run through a generic descrambler?
Well, MOST if not all passwords are stored via a certain font , can’t think of the damn name, of course not the actual data base but what the original user typed word/combination is used. So it would be a easy crack there, but i’m not sure about your second question it’s damn 2 am lmao
3:29 i didn’t know this, but i already use opaque rectangles because there’s no blur option and the rectangle is easier, faster and more precise to align with the text
The thing now is also make sure you're covering EVERYTHING with an even rectangle. If we're able to see the descendants and ascendants, people can work out probable combinations and see patterns on certain words
Oh wow, this is actually something I was wondering if it was possible for a long time. All you need is the font and font size which can be derived from surrounding text and you can eventually find a match for the pixelation, same would work for blur
I always use Paint tool (you can use GIMP, Photoshop, etc.) and mark out everything in black, so there is no way one can retrieve it using any kind of tool.
I find that instead of mosaic obscures, it's simpler to cut out the region and colour the region the same as the surrounding background. I did that with a licence plate, and it worked pretty well.
This is so cool because I have had the idea that it in theory should be possible to unblock sensor blocking of faces for years. Although that idea is a bit different. That idea is based on tracking the movement of the camera and filling in pixels based on the colour changes of the fixed blocks with the help of camera movement.
I just realized, this would be the PERFECT kind of thing for really basic image processing AI. Black and white input, text output, all necessary context is already provided in the image. Doesn't get much easier.
another thing that is important when blocking out text with solid colour is to have an 8 or more pixel border around the text since some compression algorithms can leak hidden text that way (if editing say a screenshot, this will be an issue)
I always censor stuff manually with an opaque color line drawn by hand so that any shape the final line has only provides data on how shaky my RSI-damaged hand/wrist is today :P
The other thing is for soft blurring methods it's sometimes difficult to know how much of the original information is still in the blurred area. Like, for mosaic black and white, the upper bound is 1 byte per block. That's quite a bit, especially since character distribution tends to be uneven and officials. A paragraph of English text is probably not actually more than 1-2 bits per character. Meaning a block 2 characters wide and 2 characters tall might potentially not be deleting any Information, nor is it rearranging information in a cryptographically secure way. Long story short, if your blur blocks aren't *sentence-sized,* don't expect it to keep a dedicated attacker out. But with guassian blur, unweighted neighborhood blur, linear blur, diffraction blur, etc you can't really tell how much information you are leaving available. Our upper bound is 3 bytes pixel. That is, it's quite possible that you chosen convolution is 100% reversible. Pixel-swapping schemes are more probabilistic but you could end up creating a solveable puzzle. But even if it's not fully reversible, educated guesses go a long way. The attacker usually doesn't need to be fully correct, they just need to narrow it down to a guessible possibility space. If you start with a fairly secure 2^128 possible guesses then give them 96 bits of information, that is now just 2^32 guesses they have to try. The difference between guessing it in a second and guessing it in billions of times the age of the universe.
I imagine you could get even better results when using a program that's similar but more fleshed out and for moving pixelated text (like the zoom on the top secret document you showed). That'd be a real threat to a lot of video creators if anyone put the work into it.
I just add new text on top of my pre-existing text 2 or 3 times and then do gaussian blur. This way you can tell text was there and it looks more aesthetically pleasing than a solid color bar, but you won't ever decipher it from the image even if you could get rid of the blur.
Had a project manager sent us a contract with a client to our full team so we would understand the service level agreement. He just removed the financial part where the salary of each member profit mark up etc was. however I don't quite remember but I think it was in the cloud or something like that so you could just check the revision history and see the full document.
Just use black rectangles and problem is solved! The vector of attack here is similar to the md5 hash brute force technique - same symbols generated same output. Good luck with something like a Bcrypt... or black rectangles! :)
The problem starts with different font faces, font sizes, font weights, font spacing, font colors, background colors, zoom values and the fact that each raster program uses slightly different mosaic algorithms. Basically, if you use the exact same font face, font size, font weight, font spacing, font color, background color, zoom value and mosaic algorithm as the creator of the examples, your text might get decoded. In any other case, the probability of decoding text like that is extremely low (close to 0).
There are tools used to identify a font used in images, so maybe you'd get better results if you provided your own db-sequence image in the font your "victim" uses, maybe you'd get better results?

With many fonts you can also guess the message using just one or two pixels from the top or bottom (especially if they are words or names), so make sure you cover the entire word even when using an opaque box.
This is why i only use blackout when censoring, Since you can make out the shape ALWAYS, even way back before any of this, we can already see what a shape is supposed to be behind a pixelation, a car, a person, or etc, so it's only time text can be revealed what's behind them
I always tought it is possible even more so, if you know the font the text was originally in. the most crude way would be to just bruteforce each letter to see how it looks blurred, and match it with the picture
yes that's awesome! always suspected that style of censoring especially since it uses complex colours rather than like a palette of 8 shades, gave too much info and could be deciphered. Hopefully with this tool people will be more cognisant of basic security
I thought it was old known fact. I've read articles about it at least 6 years ago. Another commonly overlooked vector of attack is recovering passwords from video using keyboard sound. (Pressing different keys produces different sounds, with enough samples, it's possible to recover the password)
I always figured this was possible. Its just the law thermodynamics. Energy is not created or destroyed, it just changes. If you reverse the entropy you get back the original.
I think using the non masked text to adjust font size, spacing and kerning will give better results than trying to preencode several options (with/without spacing etc)
Go in paint and use the black brush. The only way I found possible to send working documents with data possible to leak. The ending file will only contain pixels, and needed pixels will be black.
I suspect that it will be improved a lot when it begins to get the font from the rest of the document. This would allow it to generate the correct pixelated sequences. Note that pixel offsets are also going to be an issue, so the same text might get blurred a thousand different ways depending on where the blur box is vs the text it contains. On another front I kind of like the idea of using a totally white or black box and then superimpose an insult and pixelate that.... This is not a bad start, but it is only a start. It will get better.
My school teacher send me a pdf file with white rectangles over it, when reverted to word it removed those rectangles and I was able to see the results xD Is this comment rly the 3rd highest lol??
Very interesting. Many people also use Gaussian Blur for bluring images, which is just a simple multiplication on the pixel values. My guess would be you could invert the blur even easier since no data is inherently lost. 🤔🤔
Years ago they identified some sex trafficker by reversing the swirl filter on an image where he had used swirl over his face to try to hide his face. I think that was way back in 2004.
Do the coloured markers on iOS stay transparent even if you do lots of layers? I tried that and then adjusting colours in Lightroom and you can’t see the text but I’m not an expert
You can also use some Gothic/Decorative Typeface on your documents and browser, that way, it will get even harder for the script to work, because the letters will produce different patterns. Or yeah, just use solid colors, that work as well
The mistake almost seems intentional. If you transform anything using any formula or algorithm it is simply a matter of reversing the equation. There is an ancient example using ink and oil in a cylinder that can spin one way to blend the ink and oil and then spin the other way to return the two fluids to their nearly original separated states.
It's just like the age old problem of getting random numbers from orderly machines and mathmatics. Or like the Enigma cipher. If something is hidden by transforming it in a specific and very orderly way, it can usually be reversed!
I was worried this would happen one day... so I either made the censor with lower res, a different style of mosaic (like hex/triangle) or just black/background colour.

even more so, if you know the font the text was originally in. the most crude way would be to just bruteforce each letter to see how it looks blurred, and match it with the picture
Can’t wait for next video 👍🏻👍🏻👍🏻🇬🇧
i was expecting this to use a neural network. cool that it didn't!
yes that's awesome! always suspected that style of censoring especially since it uses complex colours rather than like a palette of 8 shades, gave too much info and could be deciphered. Hopefully with this tool people will be more cognisant of basic security
Thank you bro. You made every tutorial creators get hacked.
I read "Mario from the other side"
Well at least we can now finally confirm what the star statue in Mario 64 says
Oh my god I knew it! I never trusted blurred censoring.
Me neither
I thought it was old known fact. I've read articles about it at least 6 years ago.
Another commonly overlooked vector of attack is recovering passwords from video using keyboard sound. (Pressing different keys produces different sounds, with enough samples, it's possible to recover the password)
I always figured this was possible. Its just the law thermodynamics. Energy is not created or destroyed, it just changes. If you reverse the entropy you get back the original.
Very importante these informations ! Thank tu.
Great video- thanks!
You have a pending Windows update ;)
I think using the non masked text to adjust font size, spacing and kerning will give better results than trying to preencode several options (with/without spacing etc)
Finally, I've been waiting for something like this...
No wonder why there are so many decensored JAV popping up!
Weebs, who look back at the bit wars meme thumbnails: yes
Go in paint and use the black brush. The only way I found possible to send working documents with data possible to leak. The ending file will only contain pixels, and needed pixels will be black.
I suspect that it will be improved a lot when it begins to get the font from the rest of the document. This would allow it to generate the correct pixelated sequences. Note that pixel offsets are also going to be an issue, so the same text might get blurred a thousand different ways depending on where the blur box is vs the text it contains. On another front I kind of like the idea of using a totally white or black box and then superimpose an insult and pixelate that.... This is not a bad start, but it is only a start. It will get better.

I always try to do it manually with my brain first. 20% success rate I think
My school teacher send me a pdf file with white rectangles over it, when reverted to word it removed those rectangles and I was able to see the results xD
Is this comment rly the 3rd highest lol??
Nice!
lool
What's behind the rectangles?
Big brain
what was there
Very interesting. Many people also use Gaussian Blur for bluring images, which is just a simple multiplication on the pixel values.
My guess would be you could invert the blur even easier since no data is inherently lost. 🤔🤔
2:35 How do you install it??? I installed PIP or whatever, but whats the image library??/ what does that even mean?????
This was one of my shower thoughts lol
Hackers: time to expose people 🤫
Editor: *Censors with black boxes*
Can this be for manga too?
the "ENHANCE" Feature of CSI and other shows are coming into reality
Years ago they identified some sex trafficker by reversing the swirl filter on an image where he had used swirl over his face to try to hide his face. I think that was way back in 2004.
It's as if they never tried applying a second swirl effect (in the opposite direction) before. Of course it is reversible 🤦♂️
*_interesting_*
Do the coloured markers on iOS stay transparent even if you do lots of layers? I tried that and then adjusting colours in Lightroom and you can’t see the text but I’m not an expert
maybe they would be fully blurred out like that
You can also use some Gothic/Decorative Typeface on your documents and browser, that way, it will get even harder for the script to work, because the letters will produce different patterns. Or yeah, just use solid colors, that work as well
Imagine censoring passwords with that instead of big black 😏 line
Now some japanese "animations" can be enjoyed without something in the way, if u know what I mean 😂😂
Black boxes: _You may have outsmarted me, but I outsmarted your outsmarting_
I remember people joking about this years ago to scare people on forums. Never imagined we'd actually see it become real but it makes sense
My iPad does this thing where whenever I screenshot a password, instead of blurring it, it removes the text entirely
WAIT WHAT
Not gonna lie I was planning to build something like this but someone else did.
The mistake almost seems intentional. If you transform anything using any formula or algorithm it is simply a matter of reversing the equation. There is an ancient example using ink and oil in a cylinder that can spin one way to blend the ink and oil and then spin the other way to return the two fluids to their nearly original separated states.
Like why didn't someone think of this before it's so simple yet so smart
This project is begging for AI and ML. Stay safe kiddies 🙏🏽😂😭
"i always thought", "i think" and the music makes this video very engaging waw i love it
also this is actually terrifying
It's just like the age old problem of getting random numbers from orderly machines and mathmatics. Or like the Enigma cipher. If something is hidden by transforming it in a specific and very orderly way, it can usually be reversed!
'Hello from the other side' unpixelated looks like 'Mario from the other side'...
Oh hey, I didn't know I needed Werner Herzog talking about tech in my life.
I was worried this would happen one day... so I either made the censor with lower res, a different style of mosaic (like hex/triangle) or just black/background colour.
All those old videos are gonna get rekt now with this
Use opaque overlay and then flatten image. For iphone that would either be by screenshot or by sharing the image to save photo again.
