CRYPTOGRAPHIC TRUST SYSTEM FOR ELECTRONIC COMMUNICATIONS INTEGRITY USING TUPLE SPACES AND MESSAGING USER AGENTS

Abstract: an electronic communication system for certification of an electronic communication includes: (1) a cryptographic trust server (cts); (2) a common memory to store electronic communications; (3) a tuple server configured to generate tuple spaces; (4) a first user device; and (5) a first messaging user agent (mua) associated with the first user device. the first mua is configured to generate an mua cryptographic hash for a first electronic communication, and the mua places the first electronic communication with the cryptographic hash in the common memory, optionally with an iterative communication thread of prior electronic communications. the first mua places an alert and the location of the first electronic communication in a tuple space provided by the tuple server. the alert notifies the cts to access the common memory to review and verify or not verify the mua cryptographic hash and optionally verify or not verify a cts hash of the iterative communication thread.
