Abstract:
1. A method comprising: obtaining time information from both a first log entry of a first log and a second log entry of a second log, wherein the first log entry includes at least a first sequential rolling checksum value based at least in part on a previous log entry in the first log and a first media identifier corresponding to first media, and the second log entry includes at least a second sequential rolling checksum value based at least in part on a previous log entry in the second log and a second media identifier corresponding to second media, wherein the first log is entangled with the second log by calculation of a sequential rolling checksum value in at least one log entry in the first log based at least in part on a sequential rolling checksum value in at least one log entry from the second log, wherein the first media identifier is generated from a screenshot of a first electronic document corresponding to the first media, the second media identifier is generated from a document identifier associated with the second electronic document, and time information in the first and second logs correspond to times when the first media identifier was generated from the screenshot and the second media identifier was generated from the document identifier; and determining that the first media is related to the second media based on the time information of the first and second log entries being related.
