发明名称 METHOD, APPARATUS AND SYSTEM FOR ANTI-PIRACY PROTECTION AND VERIFICATION
摘要 A method, apparatus and system for anti-piracy protection and verification include a first projection device configured to project image frames onto a screen. A feedback device records a plurality of consecutive frames, an image analyzing module analyzes image properties of the recorded frames and a modulator creates anti-sampling system content to be projected contemporaneously with the image frames. The projected anti-sampling system content, while virtually invisible to the human eye, is detectable by sampling systems such as camcorders, thus rendering any such pirated recordings of the protected image content useless. The first projection device can include a security processor configured for comparing the recorded content with an expected content in real-time. A display enable/disable module is provided for disabling the projection of the content on the screen if the recorded content does not match the expected content.
