Abstract: A system and method for producing a visual image signal for verification of visual content contained in the visual image signal being displayed on an electronic display may include forming a verification code associated with the visual content. A visual verification code signal representative of the verification code may be generated. The visual image signal inclusive of the visual content and the visual verification code signal may be generated, where the visual image signal includes the visual verification code signal so as to be visible to a human eye when displayed. The visual image signal may be displayed.

Abstract: One embodiment of a system and method may include communicating visual content via a visual content signal to an electronic visual display for displaying between a start time and an end time. The visual content signal may be displayed between the start and end times, and an operational parameter (e.g., voltage or current) of the electronic visual display may be sensed between the start and end times. An indicator indicative of the sensed operational parameter may be recorded. The recorded indicator provides for verification of the visual content being displayed by the electronic visual display. Signature analysis may be performed on the sensed operational parameter to determine that the visual content signal was properly displayed. In addition, a visual content signal may be uniquely identified based on the signature analysis.

Abstract: A system and method for providing multiple levels of verification of content displayed on an electronic display. A verification code signal representative of a verification code may be displayed with the visual content. The verification code may be sensed and determined to verify that the visual content was displayed. A timestamp may be generated to indicate time of day that the visual content is displayed. In one embodiment, the verification code signal may be displayed in one or more colors and sensed. Verification that the visual content was displayed with correct colors may be made based on the sensed visual verification code signal. Verification that the visual content was displayed at a certain time and with the correct colors may be provided to an owner of the visual content, such as an advertiser.
