Abstract
A method and apparatus for measuring data presentation is measured for authenticity and accuracy using a cryptographic capability. The data may include both presentation data and metadata related to measuring and reporting results of outputting the presentation data. After measurement, the presentation data may be presented to an output device. The output device may be a display, a sound device or other computer output. Related statistics may be collected, for example, user identity, computer identity, time, duration, and interference from other sources. In the case of displayed presentation data, unblocked viewing area, and presentation data area size may also be collected. In an exemplary embodiment, the presence of a user and/or user interaction with the presentation data may be recorded and reported. The recorded data may be securely reported to a participating host or server, by a secure channel and/or by signing and/or encrypting.
