On Tuesdays the USPTO issues new patents. Today's Spotlight Patents concern aspects of digital watermarking and digital fingingerprinting. Assigned to Digimarc, the first patent addresses various applications of digital watermarking. Assigned to Symantec, the second patent addresses techniques to improve data loss prevention via cross leveraging fingerprints.
8,250,660, "Digital watermarking applications," assigned to Digimarc.
Methods and systems include, e.g.,: (1) steganographically embedding location information in images, where the location information is obtained from remote sources like a cell phone network or remote GPS receiver; (2) steganographically embedding participant IDs in content to ensure proper billing and royalty tracking; (3) providing fair-use content management based upon digital watermark-tracked usage; (4) providing micro-payments based upon watermarked ID cards for retailers; and/or (5) providing watermarked logon cards, such as watermarked hotel room keys, to better provide internet logon access control. Other systems and methods are provided as well.
8,250,085, "Method to improve data loss prevention via cross leveraging fingerprints," assigned to Symantec.
A method and system for improving data loss prevention via cross leveraging fingerprints of protected data is described. In one embodiment, fingerprints of sensitive data of multiple organizations are shared across data loss prevention (DLP) systems of these organizations. A DLP system of each organization monitors information content associated with this organization to detect sensitive data of other organizations, and notifies one or more users within the organization upon detecting sensitive data of other organizations. In addition, a report of external data loss detection is provided to users within an organization whose sensitive data is detected in information content of the other organizations.
