Clever, although I believe it's unethical.
It starts like this. How far from the day companies do this with the images you take with your mobile, with the videos you stream, etc.? The world will turn into a DRM fest.
- fmax30 14y agosomething like this can be used to track down someone who does bootleg recordings. Say our bootlegger buys a camera from samsung, samsung uses a water mark like this which gives out a unique device id. The bootlegger who doesn't know about this tracking thing uploads his 1080p raw video. MPAA then collaborates with samsung to find out was the bootlegger(although that would involve tracking the sale from the reseller/distributer and contacting/capturing the bootlegger).I just gave MPAA a really nice idea.
- hcarvalhoalves 14y agoI was thinking the same thing.
- theevocater 14y agoActually, imagine how much worse this could be: person on youtube posts (bootlegged | police harassment) video under one account, family video under another: bam they have you.
- jodrellblank 14y agoI was wondering recently if there's an equivalent of inkjet-dots in popular digital cameras, either deliberately added, or accidentally in noise patterns, which would allow you to link two separate images to the same camera. That could be interesting for finding people posting some photos under their real name, and then identifying their other interests they'd prefer to keep separate (legal interests or not).
- shard 14y agoIt's being worked on, you can see research papers if you google "camera sensor identification". It can also be used to detect photoshopping if you have access to the sensor noise pattern.
