Embodiment Construction

[0017] review

[0018] Embodiments described below provide techniques for filtering email based on a user's social network. Email addresses stored in the user's address book are assumed to belong to the user's friends. Therefore, as an exclusionary email filtering system, emails received from addresses stored in the user's address book are allowed and not flagged as spam. A user's friends (as identified by addresses in the user's address book) that are part of the user's social network may also be believed to have "friendly" addresses stored in their address book. Thus, in addition to explicitly trusting (i.e., not marking as spam) messages received from addresses stored in the user's address book, messages received from addresses stored in the user's friend's address book are also acceptable. Faithful.

Abstract

Social network email filtering is described. A user's address book includes a first group of email addresses. Those email addresses are used to identify address books that include another group of email addresses. Multiple iterations may be used to identify several groups of email addresses, representing a user's social network. When an email message addressed to the user is received, the message is trusted if the sending email address is within the user's social network. Otherwise, the message is flagged as junk mail. Varying trust levels may be applied to messages that are received based on a distance within a social network between the sending email address and the user and / or how often the sending email address appears within the social network.

Description

technical field [0001] The present invention relates generally to e-mail filtering, and more particularly to filtering e-mail based on social networks. Background technique [0002] As more and more individuals use e-mail as a communication tool, unsolicited spam e-mail has become a problem. To enable users to reduce the amount of junk email ("spam") they receive, a number of email filtering tools have been developed. One of the most effective e-mail filters is an exclusive filter based on entries in a user's e-mail address book. For example, an exclusionary email filter identifies as spam any email from an email address that cannot be found in the recipient's address book. [0003] Although this is an effective filtering technique, it is possible, however, for many e-mail messages to be identified as spam when in fact they are e-mail that the recipient intended. For example, if a user has a friend's email address in their address book, emails from that friend will be rec...
