Abstract

A secure messaging system that requires pairing of second and receiving devices via user identification credentials and the associated media access control addresses (MAC addresses) of the paired devices. Paired devices may communicate encrypted messages and deletion parameters may be established by a sending device, including immediate deletion requests. The message and the instructions are automatically decrypted by the receiving device and interpreted to provide the data and configure the deletion parameters. The system preferably manages device pairing via a remote server that is accessed by a device application.

Claims

1. A method of securely transmitting messages between electronic devices, comprising:

receiving a request to send a message from a sending device having a first media access control (MAC) address to a receiving device having a second MAC address;

confirming that said first MAC address of said sending device matches at least said one of a predetermined plurality of unique MAC addresses associated with a corresponding plurality of registered electronic devices and stored in memory, wherein each of said predetermined plurality of unique MAC addresses associated with a corresponding plurality of registered electronic devices have been paired with at least another of predetermined plurality of unique MAC addresses;

confirming that said second MAC address of said receiving device matches another one of said predetermined plurality of unique MAC addresses in said memory;

confirming that said first MAC address of said sending device has been paired with said second MAC address of said receiving device;

confirming that a first username and password associated with said sending device matches a previously registered username and password associated with the first MAC address of said sending device;

encrypting said message using a second username and password of the receiving device and the second MAC address of the receiving device if the first username and password of said sending device matches the previously registered username and password associated with the first MAC address of said sending device; and

forwarding said encrypted message from said sending device to said receiving device only if said first and second MAC addresses and said first and second usernames and passwords are confirmed as having matches in said memory and said first and second MAC addresses have been paired, and not forwarding said message if said first and second MAC addresses and said first and second usernames and passwords are not confirmed as having matches in said memory and said first and second MAC addresses have not been paired.

2. The method of claim 1, further comprising the step of pairing at least one of said predetermined plurality of unique MAC addresses with another of said predetermined plurality of unique MAC addresses in response to a pairing request received from a requesting device having one of said predetermined plurality of unique MAC addresses that is forwarded to and accepted by another of said plurality of registered devices.

3. The method of claim 2, further comprising the step of terminating said pairing at request of either device involved in said pairing.

4. The method of claim 1, wherein said encrypted message further comprises a deletion parameter that specifies how long said encrypted message is to be retained by said receiving device.

5. The method of claim 1, further comprising the step of causing the deletion of said encrypted message from said receiving device in response to a deletion request from said sending device.

6. The method of claim 1, wherein the step of registering at least one of said predetermined plurality of unique MAC addresses associated with a corresponding plurality of registered electronic devices further comprises the step of requiring the presence of downloadable software on each electronic device to be registered.

7. A system for securely transmitting messages between electronic devices, comprising:

a memory having a database containing a plurality of media access control (MAC) addresses uniquely corresponding with a plurality of electronic devices;

a server programmed to establish at least one pairing between two or more of said electronic devices and save said pairing relationship with said database, to confirm that a first username and password of a sending device having a first MAC address matches a previously registered username and password associated with the first MAC address of said sending device, to encrypt a message using a second username and password of a receiving device and a second MAC address of the receiving device if the first username and password of said sending device matches a previously registered username and password associated with the first MAC address of said sending device, to forward said encrypted message from the sending device to the receiving device having the second MAC address if said database contains said sending device and said receiving device have a previously established pairing relationship based on said first and second MAC addresses and said first and second usernames and passwords are confirmed as having matches, and to not forward said message if said first and second MAC addresses and said first and second usernames and passwords are not confirmed as having matches in said memory and said first and second MAC addresses have not been paired.

8. The system of claim 7, wherein said server is programmed to establish at least one pairing by forwarding a request from a first device registered in said database to a second device registered in said database and receiving from said second electronic device an acceptance or denial of said request.

9. The system of claim 8, wherein said server is further programmed to terminate said pairing at request of any device within said pairing relationship.

10. The system of claim 7, wherein said server is further programmed to add a deletion parameter to said encrypted message to notify said second device to delete said message after a predetermined time.

11. The system of claim 7, wherein said server is further programmed to remotely delete said encrypted message from said second device after a predetermined time.

12. The system of claim 7, wherein said database stores, along with each MAC address, a username and password associated with each of said electronic devices in said database.

13. The system of claim 7, wherein said server is further programmed to require the presence of downloadable software on each device stored in said database.
