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.
