US Classification:

713176, 283113, 358 328

Abstract:

Systems and methods are disclosed for embedding information in software and/or other electronic content such that the information is difficult for an unauthorized party to detect, remove, insert, forge, and/or corrupt. The embedded information can be used to protect electronic content by identifying the content's source, thus enabling unauthorized copies or derivatives to be reliably traced, and thus facilitating effective legal recourse by the content owner. Systems and methods are also disclosed for protecting, detecting, removing, and decoding information embedded in electronic content, and for using the embedded information to protect software or other media from unauthorized analysis, attack, and/or modification.

13/208768

Inventors:

William G. Horne - Lawrenceville NJ, US
Lesley R. Matheson - Discovery Bay CA, US
Casey Sheehan - Hollister CA, US

Assignee:

Intertrust Technologies Corporation - Sunnyvale CA

International Classification:

H04L 9/32

US Classification:

713187, 713176, 726 26

Abstract:

Software self-checking mechanisms are described for improving software tamper resistance and/or reliability. Redundant tests are performed to detect modifications to a program while it is running. Modifications are recorded or reported. Embodiments of the software self-checking mechanisms can be implemented such that they are relatively stealthy and robust, and so that they are compatible with copy-specific static watermarking and other tamper-resistance techniques.

International Classification:

H04L 9/00

US Classification:

713178

Abstract:

A method of establishing the integrity of an audit record set is described. The method comprises receiving a set of audit records and generating a first set of random values wherein each audit record in the set corresponds to at least one value of the first set. The method further comprises generating a second set of values based on an audit record and a corresponding value of the first set for each audit record in the set and generating a summary value based on the second set of values. The method further comprises certifying the summary value to generate an integrity certificate enabling verification of the integrity of the audit record set and storing the audit record set and at least one of the first set of values and the generated digital signature.
