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.

Sensor fingerprint matching in large image and video databases

Host malware (or change) may be detected by (1) receiving baseline set of response time information for each of one or more transactions involving (A) the host and (B) at least one peer of the host, (2) determining or receiving a later set of response time information for each of the one or more transactions involving the host and the at least one peer of the host, and (3) determining whether or not host slowdown has occurred using the baseline set of response time information and the later set of response time information. The execution of a host malware (or change) protection policy may be controlled using at least the determination of whether or not host slowdown has occurred.
