System and method for secure real-time digital transmission

Abstract

A system and method are provided for secure digital transmissions. The method comprises: accepting a digital message; compressing the digital message into a file; generating a pseudo-public-key in response to the public-key and a server device identifier; using the pseudo-public-key from a public/private-key pair to encrypt the first n bytes of the file; and, transmitting the encrypted file. In some aspects of the method, accepting a digital message includes accepting a digital message from a server device, such as a digital camera, having a serial number. Then, generating the pseudo-public-key includes using an algorithm to combine the public-key and server device serial number information. In other aspects, accepting a digital message includes accepting a digital message from a server device having a user-selectable digital code setting. Then, generating the pseudo-public-key includes using an algorithm to combine the public-key, the digital code setting, and/or the serial number. The method further comprises: receiving the encrypted file; generating a pseudo-private-key in response to the private-key and the server device identifier; using the pseudo-private-key to decrypt the first n bytes of the file; decompressing the decrypted file; and, reading the digital message.
