Method and system for authentication of electronic communications
| DWPI Title: Electronic mail authenticating method, involves comparing message sent to third party authentication entity with information about electronic mail communication, and delivering communication to recipient |
| 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. |
| Use: Method for authenticating electronic mail. |
| Advantage: The method eliminates the problem of fake email sender addresses, which fools recipients into delivering trusted information to an unintended recipient, or communicate false information, among other unwanted consequences, and also eliminates the widespread problem of bounced messages cluttering the mailbox of a sender that never sent them. The method allows the recipient to automatically verify that their incoming messages match the data of their sender's outgoing communications, such that the mismatches are used to filter out fake messages assuming stolen identities. The method certifies individual communications at particular dates, times and between particular senders and receivers, thus avoiding the pitfalls of digital signature thefts. |
| Novelty: The method involves providing a sender (S) of electronic mail with a secret authenticating code (20), and sending a message (M) from the sender to a third party authentication entity (AA), when the sender sends an electronic mail communication to a recipient (R). Information (30) e.g. subject, about the mail communication is sent from the recipient to the entity (AA). The message sent from the sender to the entity (AA) is compared with the information about the mail communication. The mail communication is delivered to the recipient, when result of the comparison authenticates the sender. |
