Abstract
Several promising techniques have been recently proposed to bind an image or video to its source acquisition device. These techniques have been intensively studied to address performance issues, but the computational efficiency aspect has not been given due consideration. Considering very large databases, the efficiency of the sensor fingerprint based source device identification technique is described. Novel schemes that improve search complexity as compared to a conventional approach are described.
