Movie piracy...

Image and video hosting by TinyPic
Many movies are pirated using a camera
in theaters.
Maybe some of you don't know
that any camera "sees" infrared light.
To test it, pick your camera and aim
a remote (your tv remote is ok) at it.
You will see the infrared L.E.D. blinking.
Well.. I was thinking...
What if many infrared leds will be put behind
the projecting screen in theaters?
The IR light won't be seen by people.
But it will appear in recorded videos :)
Obviously this could be defeated putting an IR
filter on the cam lenses.. but that's the road imho :)

  1. I like your thinking! such genius.

  2. good idea didn't think you could see it through a camera but it tried it so cool.

  3. Glad to see a post from you, after such an absence

  4. very original
    i wonder how expensive that would be to actually do though

  5. There exist several technologies based on light tricks more advanced than simple infra-red LEDs.

  6. Except it would blind people. Just because you can't see it, doesn't mean it isn't harmful.

  7. Very nice, but it couldn't be defeated that easily. I use a IR Filter on my D-80 and is almost black. The sun has a hard time getting through it. about 99.9% is blocked, so the movie screen will still not be seen with the filter.

  8. wouldnt that make it like extreeemly hot, aiming IR light at the audience?

  14. This is a clever idea. But as Donald already pointed out, it's just a small challenge to overcome this kind of security.

  15. many Telesyncs and Camrips are from Russia/Ukrain , and there this equipment is expensive and no one cares about the Rippers

    also, most cammers using Sony HD camcorders , which have an IR Filter integrated , and every cammer will see on the Monitor that ther is something false :D
    and IR LEDs are producing a immense Heat , you cannot cool so many Leds

    at the moment EVERY secure is useless, also the "second picture" is detectable by special filters for vdubmod used from scene groups , if there are no more cam rips there will be more Screeners/DVDscreeners , and these are not Protectable

  16. Its don't worthy to put this infrared light in every theater because people who want to pirate will pirate any way, the IR filter is no so expansive, besides the quality on camera come out very poor and that's the main reason that not everyone in theaters siting with cameras, so its a free anti pirate block.

  17. it would be so expensive to put millions of led's behind the screen, the enought to screw off a recording, but i dont know, maybe just a few can srew enought a recording to make it ugly.

    ReplyDelete
  18. Donald: Sure could... Just need a pass filter that lets through only the visible wavelengths.

  19. i g2 this IDEA 3 yrs back dude
    When my robot had all infrared detector s with heat sensors
    I saw the pictorial difference

    PROBLEMS IN USING
    1) Big Infrared Heavy waves need to be emitted releases large amount of heat
    2) Special lens easily by passes it as it does not take infrared in view
    3) Its expensive damn expensive also creates a screen projector problem it needs covering and all dat crap and the filter for it is not even 100$ dude
    4) They are electro magnetic large amt is not good for gadgets!!

    Work on liux then this TP

    I m not dat good at AT codes
    Or i too would <3 to help

    I m using linux in iphone its good project man....
    D mobile installation was made by me but this jailbreak stuff is too time consuming so cant help it!!
    Atleast appreciate Dev team in a new topic!!
    They r doing an amazing JOB
    more den amazing JOB
    Linux is progressing with speed of lightning!!

    Just my personal view
    no competition

  20. AFAIK this already used in some US Cinemas.

    The beam has a kind of "code" in it, so once the movie goes on the internet, they could be able to understand where, when it has beeen filmed and possibily who (based on the prospective).

  21. Sorry, Zibri, but I'm not convinced. Cinema screens are very bright. Small infra-red lights would have the effect of shining a torch (flashlight) in a very bright room: barely noticeable.

  22. oh, i forgot you were over seas. in the united states, lots of theaters utilize this.

    ReplyDelete
  23. it's already invented and patented by a spanish man.

    ReplyDelete
  24. Oh.. I didn't know, but I guess I wasn't the only one to have this idea.

    ReplyDelete
  25. Well I thougth of that once, but then again: the image quality SUX soooo bad and audio is often terrible as well, not to mention people in the audience talking and walking up/down the hallway, do we really need a hint to know its a pirated copy??

    ReplyDelete
  26. It seems it wasn't such a dumb idea afterall..

TP-LINK Configuration file encrypt and decrypt.

Here we go! TP-Link is another company that thinks that security by obscurity could ever work. If you "backup" the configuration from most TP-Link routers, you will get a .BIN file which is "encrypted". Use this utility below, to decrypt it (so you can edit it) and encrypt it again. Have fun.

Your own CORS ANYWHERE proxy on CLOUDFLARE

Hello again! Many of you probably hate as I do CORS because it hinders the very nature of internet, which is SHARING. There are some services to circumvent this commercial  restriction, one of these is the famous "cors anywhere". So yesterday I decided to make my own and allow you to make your own in only 2 minutes. To do so you just need a cloudflare account (can be set up in 1 minute). The you can upload my worker on it and have your personal very fast cors proxy! So, enough talk, just head to:  https://github.com/Zibri/cloudflare-cors-anywhere The is also a demo online at: https://test.cors.workers.dev Enjoy! Zibri

Powerline Ethernet fun and secrets.

Many 200 Mb/s powerline adapters nowadays are based on the INTELLON 6300 chipset. Despite what can be thought looking at them, they are all using the same hardware and firmwares. I heard many people with Netgear XAV101 or Linksys PLK 200 or PLE 200 having problems after firmware updates and many other people with other brands having much more problems because of lack of support or configuration/upgrade utilities. So let me explain a few things I learnt studying them. Many of 200 Mb/s powerline ethernet adapters follow the "HomePlug AV" standard. (85 Mb adapters use HomePlug 1.0 standard which is completely different). This standard uses ethernet broadcast packets using the HomePlug AV protocol. The interesting thing is that their firmware is made of two different parts: a .PIB file (Parameter Information Block) and a .NVM file (the code itself). In the P.I.B. there are many interesting things: The branding (mac address, device name, etc) and the tone map. I test...
