System and method for message filtering by a trusted third party
First Claim
Patent Images
1. A method for filtering messages using a computer comprising:
- receiving an incoming message intended for a recipient at the computer along a message path through physical geographic regions to the recipient;
determining at least one filter algorithm to apply to the message by using the message path through physical geographic regions to the recipient in order to determine a required visa type, wherein the required visa type is associated with the at least one filter algorithm;
applying the at least one filter algorithm to the message;
generating an authenticated visa for the message path through physical geographic regions according to the at least one filter algorithm that may be used to identify the at least one filter algorithm that has been applied to the message andsending the message and the authenticated visa downstream from the computer along the message path, wherein the message path downstream from the computer includes a public network.

Abstract
A method and system for providing message filtering is described. In one configuration, a trusted third party system affixes an evisa to an electronic message thereby providing an indication relating to a filtering/prioritization procedure. The evisa may utilize cryptographic methods to authenticate a message and provide non-repudiation from the trusted third party.

18. A method for filtering messages using a trusted third party computer comprising:
-
receiving an incoming message intended for a recipient at the trusted third party computer along a message path through physical geographic regions to the recipient; determining at least one filter algorithm to apply to the message using the message path through physical geographic regions to the recipient and rules provided by a governmental entity that does not operate the trusted third party computer; applying the at least one filter algorithm to the message; generating a cryptographically authenticated visa according to the at least one filter algorithm; attaching the visa to the message; and sending the message with attached visa downstream along the message path toward the recipient including through a public network.
