Vipul's Razor is a distributed, collaborative, spam detection and filtering
|
|
network. Razor establishes a distributed and constantly updating catalogue
|
|
of spam in propagation. This catalogue is used by clients to filter out
|
|
known spam. On receiving a spam, a Razor Reporting Agent (run by an end-user
|
|
or a troll box) calculates and submits a 20-character unique identification
|
|
of the spam (a SHA Digest) to its closest Razor Catalogue Server. The
|
|
Catalogue Server echos this signature to other trusted servers after storing
|
|
it in its database. Prior to manual processing or transport-level reception,
|
|
Razor Filtering Agents (end-users and MTAs) check their incoming mail against
|
|
a Catalogue Server and filter out or deny transport in case of a signature
|
|
match. Catalogued spam, once identified and reported by a Reporting Agent,
|
|
can be blocked out by the rest of the Filtering Agents on the network.
