Appl. No.:

10/128182

Inventors:

Binyamin Pinkas - Jersey City NJ, US
Tomas Sander - New York NY, US
William G. Horne - Lawrenceville NJ, US

Assignee:

Intertrust Technologies Corp. - Sunnyvale CA

International Classification:

H04L 9/00

US Classification:

705 75, 713168, 380277

Abstract:

Systems and methods are provided for managing the transfer of electronic files. In one embodiment, a sender transfers an encrypted version of a file (such as a digitally encoded audio track, movie, document, or the like) to someone who wishes to receive it. The receiver computes a hash of the encrypted file, and sends it to a trusted third party. The trusted third party compares the hash that was computed by the receiver with another hash computed by the sender. If the two hashes match, the third party sends the file decryption key to the receiver. In some embodiments, the receiver may also send the third party payment information so that the sender, the content owner, and/or the third party can be paid for their role in the transaction. In a preferred embodiment, the payment information is only sent to, and/or used by, the third party once the third party has confirmed to the satisfaction of the receiver that the encrypted file in the receiver's possession will decrypt correctly. In some embodiments, the sender computes a hash of the encrypted version of the file and sends it directly to the third party.

International Classification:

H04L 9/32
H04L 29/06

US Classification:

713176, 713150, 713168, 713175, 713177

Abstract:

One or more methods of generating a pseudonymizable document are described. A method comprises receiving a set of subdocuments and generating a first set of random values wherein each subdocument in the document corresponds to a first set random value. A second set of values is generated based on a subdocument and a corresponding value of the first set random value. A set of pseudonyms is generated wherein each subdocument in the document corresponds to at least one pseudonym of the pseudonym set. A third set of values is generated based on the second set of values and the pseudonym set and a summary value is generated based on the third set of values.

US Classification:

705 75, 707747, 713168, 380277

Abstract:

Systems and methods are provided for performing transactions and managing communications using a trusted third party. In one embodiment, a sender transfers an encrypted version of a file (such as a digitally encoded audio track, movie, document, or the like) to someone who wishes to receive it. The receiver computes a first hash of at least a portion of the encrypted data content, and sends the first hash to a third party configured to compare at least a portion of the first hash to at least a portion of a second hash. The receiver receives a file decryption key from the third party, and decrypts at least the portion of the received encrypted data content with the decryption key. In some cases, multiple hashes of the encrypted data content may be computed, each using a different portion of the encrypted data content.

US Classification:

726 25

Abstract:

A method for analyzing risk to a system, the method being carried out by a computer having a processor and system memory, includes the steps of inputting data representing multiple threat objectives that comprise the risk, calculating a residual risk for each threat objective in view of a plurality of control mechanisms, and generating output representing an overall residual risk to the system that is a combination of the residual risks.
