Appl. No.:

10/886891

Inventors:

Jing Zhu - Fremont CA, US
George Hu - San Jose CA, US

Assignee:

Yahoo! Inc. - Sunnyvale CA

International Classification:

H04L 9/00

US Classification:

726 4, 726 14, 726 18, 713154

Abstract:

A Trust Email Datastore (TED) system is employed to maintain a list of message addresses with associated trust ratings. The trust rating of a message address is derived from an underlying message address relationship network around the message address of interest through various network related activities such as message sending, forwarding, deleting, blocking, marking as is/is not spam, saving to address book, etc. There may be at least two components of the trust rating between two message addresses. One component of the trust rating, called a relationship trust, may be determined based on proximity of two message addresses in a message address relationship graph. Another component of the trust rating is substantially independent of the positions of two message addresses in the message address relationship graph, and is referred to as a universal trust rating. The trust rating components can be combined and employed for spam filtering.

US Classification:

Abstract:

A community-based “green list” (CGL) message filter for mail service providers. The CGL filtering enables trusted messages to be delivered directly into a user's inbox folder and other messages to be delivered to other folders associated with the user. The CGL filtering indicates which messages are sent from those message addresses listed as friends in the user's personal address book. Also, the scope of CGL filtering includes more than those message addresses that the user interacts with directly (one degree of separation). For example, the CGL filtering also evaluates message addresses that are connected more remotely to the user through other nodes (users) in the online community that are located multiple degrees of separation away from the user.

International Classification:

G06F 15/00
G06F 15/30

US Classification:

726 4, 726 14, 726 18, 713154

Abstract:

The invention is directed to implementing a trust rating subscription model for email addresses and/or domains in a trust-oriented email network that is supported by a deployment of a trusted email database (TED) system. The TED maintains the trust rating for individual email addresses relative to the recipients. Also, the subscription model enables the email end users and inbox service providers to register with the TED to obtain the trust rating of a specific email sender relative to the recipient. This trust rating may then be used by the email end user or an inbox service provider to filter spam, if the sender is untrusted, or deliver the message to an inbox, if the sender is trusted. A sender (individual email address, domain, and the like) can also subscribe and obtain limited rights to email subscribers of the TED system.

Abstract:

Apparatuses and methods for dynamically adjusting carrier sensing threshold levels in a wireless, such as CSMA, system. A station may use the carrier sensing measurement made in normal CSMA operation to determine a threshold level for the local station, and transmit the determined level to other stations in the system. The station also receives similar information from other stations in the system and determines, based at least in part on the information received and the local determined threshold level, an optimal carrier sensing threshold level.
