The dots are hard to see because they only appear for 1 frame duration. Videos typically play at 30 frames per second, so these dots only appear at 1/30th of a second. They are usually at the beginning of scenes you download, but they also appear throughout the rest of the video.
I finally realized that this is Legalporno's new antipiracy technology. Let me explain my theory:
1. Every you stream or download a video, Legalporno servers add a unique set of dots to the video you are downloading. By unique, I mean to say that the position of these dots is like a barcode on a product that you buy, and that barcode corresponds to your account.
2. If you illegally distribute a legalporno video, the dots in the frames of the video will act like a barcode to which will link the illegally distributed videos to your account.
3. Legalporno will then know the identify of the person that is illegally distributing their material.
The thing about this technology is that it's probably very computationally intensive to add random barcodes every time someone watches a video.
Therefore, the higher the resolution of the video, the more computing power you will need to generate the barcode.
I predict that this will require a lot of computer power from legalporno.com, a lot more than normally hosting a website.
Weaknesses:
1. People will use stolen credits to distribute LP material. Even if legalporno identifies the culprit, they'll be blaming the victim of credit card theft and won't actually be able to catch the real culprit.
2. People can have their passwords stolen, so and they might download the videos for malicious purposes without the account owner's knowledge.
3. Piracy helps businesses make money. This may seem counterintuitive, but it's actually true as this study explains: http://www.washingtonpost.com/blogs/the ... make-money.
I'm interested to hear Legalporno staff and user comments on these issues.
