Abstract:

A method for protecting digital content from copying and/or other misuse as it is transferred between one or more computationally constrained devices over insecure links, includes preliminarily authenticating that both a content source and a content sink are compliant devices, and transferring content between compliant devices. In a further aspect of the invention, in the background, concurrently with the transfer of content, at least a second cryptographic process is performed. In an embodiment, establishing a preliminary control channel includes exchanging random challenges between devices, encrypting, under a shared secret key, and hashing the exchanged random challenges, exchanging the results of the encryption and hash functions and then verifying that the appropriate results have been generated.

International Classification:

G06K009/00

US Classification:

382154, 382173, 382219, 345419, 348586

Abstract:

The present invention is a method and apparatus to segment a three-dimensional scene having foreground and background regions. Regions in stereo images of the 3-D scene are matched. The stereo images include left and right images. Ranges of matched regions are computed. The foreground region is separated from the background region using the computed ranges of the matched regions.

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

H04M 11/00

US Classification:

455406, 455409, 455410, 705 26

Abstract:

Techniques are disclosed for protecting privacy of parties to electronic transactions, such as transactions conducted through a GSM network. An anonymity service provider receives orders directed from its subscriber to a recipient for goods or services, along with information about its subscriber. The anonymity service provider relays the order to the recipient but withholds information about the subscriber, as the subscriber directs. The recipient receives payment for the good or service by way of a voucher from the anonymity service provider.

Appl. No.:

10/951173

Inventors:

Mihai Costea - Redmond WA, US
David W Aucsmith - Bellevue WA, US

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 11/00

US Classification:

726 22, 726 23, 726 24

Abstract:

The present invention provides a system and method of tracing the spread of computer malware in a communication network. One aspect of the present invention is a method that traces the spread of computer malware in a communication network. When suspicious data characteristic of malware is identified in a computing device connected to the communication network, the method causes data that describes the state of the computing device to be stored in a database. After a specific attack against the communication network is confirmed, computing devices that are infected with the malware are identified. Then, the spread of the malware between computing devices in the communication network is traced back to a source.

David Aucsmith - Portland OR, US
John Richardson - Portland OR, US

International Classification:

H04L009/00

US Classification:

713/200000

Abstract:

Detecting intrusions includes detecting a possible security problem at a client location, transmitting notice of the possible security problem across a network in real time to a home location remotely located from the client location, determining at the home location an anomaly based on at least the possible security problem, and transmitting notice of the anomaly in real time to the client location.
