Assignee:

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.

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.

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.

US Classification:

709206, 709204, 709205, 715752

Abstract:

The invention relates to determining electronic text communication distributed in bulk is likely solicited. In one step, a first electronic and a second electronic submission are received. It is determined that the first electronic submission is likely solicited. A first portion is extracted from the first electronic submission and a second portion from the second electronic submission. The content of the first electronic submission influences extraction of the first portion, and the content of the second electronic submission influences extraction of the second portion. A first code is determined for the first portion and a second code is determined for the second portion, where the first code is indicative of the first portion and the second code is indicative of the second portion. The first code is compared to the second code. It is determined that the second electronic submission is likely solicited, at least in part, in response to comparing the first code to the second code.

International Classification:

US Classification:

709206, 726 2, 726 22

Abstract:

The invention is directed to a system and method for determining if a “spam” message is originating from a messaging account by challenging a particular client's outbound email usage with a test that requires verification of content that is easily understood by a human being, not an automated computer program such as those used by “spammers. ” If a limit on the number of recipients for outbound messages has been exceeded, a test is presented the next time a client attempts to send a message. The client must successfully answer the test within a relatively short period of time or else the ability to send messages will be disabled. Once disabled, the client can reinstate the ability to send messages by contacting a representative of the message system out of band, e. g. , a telephone call to confirm legitimate outbound email use.

US Classification:

370252, 375260

Abstract:

A device in a wireless network receives signals and determines media access control (MAC) slot boundaries of the received signals. The MAC slot boundaries are averaged in time, and a local slot boundary is modified in response thereto. The local MAC slot boundary is modified by less than ten percent of a short interframe space until the local MAC slot boundary is within one orthogonal frequency division multiplexing (OFDM) cyclic prefix duration of the averaged MAC slot boundaries.

International Classification:

G06F 1730

US Classification:

707 10

Abstract:

A system updates a remote (server) database in a network. The network comprises a global server coupled to a local client and to a remote client. The local client includes a browser for establishing a communications link with a web server on the global server. The global server has server database memory for storing independently modifiable copies of workspace data maintained by personal information managers (PIMS) or other data stores on the local client and has PIM Downloadables for interfacing with these PIMs. The local client requests synchronization capability for a particular PIM. The global server sends a PIM Downloadable corresponding to the particular PIM to the local client, which installs and initiates execution of the PIM Downloadable. Accordingly, a user interface receives information designating a database containing the workspace data to be synchronized and information selecting a synchronization mode such as one-way replace, one-way merge or two-way synchronize. A PIM interface instructs the particular PIM to retrieve the workspace data to be synchronized.
