Abstract:
1. A computer adapted to report the presentation of data comprising: a port for bidirectional communication with an external server via a communication network for receiving advertising data; an audio/video controller coupled to the port, adapted to process and output the advertising data received via the port to an audio/video device and to report to an external server a statistic corresponding to processing and outputting at least a portion of the advertising data at an output of the audio/video device, wherein the advertising data includes presentation data, a digital signature, and metadata, the metadata including a universal record locator (URL) of a server to which to report the statistic and wherein the statistic includes at least a time when the advertising data is output, wherein the audio/video controller uses the metadata for one of identifying the at least a portion of the presentation data for cryptographic confirmation and identifying an address for sending the statistic related to the presentation data to the output device; a cryptographic unit to compute a hash for measuring at least a portion of the presentation data responsive to the audio/video controller presenting the presentation data, wherein the audio/visual device determines the authentication of the presentation data by comparing the hash of at least a portion of the presentation data calculated by the cryptographic unit to a previously determined hash, then displaying the presentation data if the two hashes match; and an output device coupled to the controller, wherein the controller causes the cryptographic unit to digitally sign the statistic and send the statistic corresponding to presentation of the at least the portion presentation data via the port to the server indicated by the URL.
