Appl. No.:

11/400876

Inventors:

Liviu Iftode - Princeton NJ, US
Gang Xu - Piscataway NJ, US

Assignee:

AT&T Intellectual Property II, L.P. - Atlanta GA
Rutgers, The State University of New Jersey - New Brunswick NJ

International Classification:

G06F 7/04

US Classification:

726 5, 713155, 713156, 713164, 713165, 713166, 713167, 713168, 711152

Abstract:

A system and method of providing trusted service transactions includes associating a commitment with a remote service. The commitment includes a trusted list of runtime dependencies to execute a transaction. The method includes monitoring an actual list of runtime dependencies invoked during execution of the transaction using a trusted monitor. Execution is blocked if a deviation of the actual list from the trusted list is detected. Therefore, a completed transaction is allowed only if no deviation is found between the trusted and invoked list of runtime dependencies. A certificate authority in cooperation with software vendors preferably provide a signed commitment. The commitment is delivered by the provider to a user upon request and verified by the requester. The transaction is then executed by the user. Therefore, trust is verified before and during the transaction and privacy of data is guaranteed after completion.

US Classification:

713156, 713164, 713165, 713166, 713167, 713168, 726 4, 726 5, 711152

Abstract:

A system and method to ensure trustworthiness of a remote service provided by a service provider. The method includes monitoring runtime dependencies invoked during execution of a service transaction associated with the remote service, the service transaction being requested by a service requester. The method further includes determining whether a deviation exists between the runtime dependencies and a trusted list of dependencies associated with the remote service. The method also includes blocking execution of the service transaction based on determining that the deviation between the runtime dependencies and the trusted list of dependencies exists.

Assignee:

AT&T Intellectual Property I, L.P. - Atlanta GA

International Classification:

G08C 15/00

US Classification:

370252, 709226

Abstract:

A method, network, and computer program product are provided for traffic flow quality of service. A quality of service priority table is received for services defined by a user at the network, and the quality of service priority table includes quality of service levels for the services. Traffic flows are determined to correspond to packets being communicated over the network for the user. The traffic flows are mapped to services. The traffic flows are mapped to the quality of service levels for the services. The quality of service levels are assigned to the traffic flows as assigned quality of service levels corresponding to the services. Each of the traffic flows is routed over the network according to its assigned quality of service levels, respectively.

International Classification:

G01C 21/34

US Classification:

701118, 701410, 4554565

Abstract:

A cellular-based live traffic service that does not require pre-deployment of infrastructure or GPS-enabled devices uses signals provided by cellular devices to determine course resolution localization and tracking information of the cellular devices. Specialized statistical analysis is performed on the course resolution data to infer the fine resolution positions of the cellular devices. In an example embodiment, the localization and tracking information is provided on a map, or the like, to show relative position and/or trajectory of cellular devices.

International Classification:

G06F 15/173

US Classification:

709229, 709226

Abstract:

A method includes sending a first redirect instruction to a first client in response to a first session request received at a service address, and establishing a first session with the first client in response to a second session request received at the first redirect address indicated by the first redirect instruction. Additionally, the method includes determining a first service interval has passed, and sending a second redirect instruction to a second client in response to a third session request received at the service address after the first service interval has passed. The method still further includes establishing a second session with the second client in response to the fourth session request received at the second redirect address indicated by the second redirect instruction after the first service interval has passed, and rejecting the fifth session request received from a third client at the first redirect address after the first service interval has passed.
