Abstract
A system and method attest the veracity of audiovisual depictions by inferring motion of the device recording those depictions from the audiovisual data, and comparing this inferred motion with contemporaneously sampled sensor data from that device, such as accelerometer or GPS data. If the inferred motion sensibly corresponds to changes in the other sensor data, then the video is determined to be authentic. Otherwise, an anomalous condition is signaled, altering the viewer that the video may have been digitally altered.
