Abstract
A method and system to authenticate electronic communications, such as email. A trusted third party records information of each of sender's communications, such as date, time and recipients. Recipients are allowed to verify if their incoming messages match the data of their senders' outgoing communications. Mismatches can be used to filter out fake messages assuming stolen identities.
