摘要： A method for generating a signature for an end user device is disclosed. The end user device (180) comprises at least video display hardware (106) and video display software. The method comprises: processing video data by the video display hardware (106) and the video display software, thereby altering at least a portion of the video data according to a characteristic of at least one of the video display hardware (194) and the video display software to form altered data; forming the signature at the end user device (180) based, at least in part, on said altered data; generating a user profile for said end user device (180) using said signature; and transmitting said user profile to a headend (104) for use in uniquely protecting content to be sent to said end user device (180).
