Abstract

A system for sterilizing data sent through electronic messages includes first computing circuitry configured to receive a first electronic communication including first data having executable code and generate optical data representative of the first data. The system further includes second computing circuitry configured to receive the optical data from the first computing circuitry, convert the optical data into second data representative of the optical data, and transmit a second electronic communication that includes the second data and omits the first data.

6. The system of claim 1, wherein generating the optical data representative of the first data comprises capturing an image representative of the first data that is displayed on a monitor associated with the first computing circuitry.

7. The system of claim 1, wherein the first computing circuitry is further configured to transmit to the second computing circuitry an indication that the first electronic message was received and is ready for conversion, and wherein converting the optical data into the second data representative of the optical data comprises converting the optical data into the second data representative of the optical data after receiving the indication that the first electronic message was received and is ready for conversion.

8. The system of claim 1, wherein the optical data further comprises data representative of at least one of a sender'"'"'s electronic message address, a file type, a file name, and a file size, and wherein the second computing circuitry is further configured to determine how to convert the optical data into the second data representative of the optical data and to which electronic message address to transmit the second electronic communication based on the data representative of at least one of the sender'"'"'s electronic message address, the file type, the file name, and the file size.

9. The system of claim 1, wherein the first computing circuitry is further configured to:
