1. A method for decoding an encrypted file, said method comprising:
receiving, by a recipient computer of a recipient from a sender computer of a sender, the encrypted file, wherein the encrypted file has a filename that includes an encoded address in the filename, wherein the encoded address identifies where a voice check ticket is stored, wherein the voice check ticket comprises voice check text, and wherein a prior name of the encrypted file and the encoded address are merged together within the filename; extracting, by the recipient computer, the encoded address from the filename; accessing, by the recipient computer, the voice check ticket at the encoded address extracted from the parsed filename; receiving, by the recipient computer from the voice check ticket, the voice check text; displaying, by the recipient computer, the received voice check text visually on a computer display of the recipient computer; prompting, by the recipient computer, the recipient to read aloud the displayed voice check text; receiving, b the recipient computer, an audio signal from a reading aloud by the prompted recipient of the displayed voice check text; receiving, by the recipient computer from the server computer, an identifier of the recipient; transmitting, b the recipient computer to a server computer comprising a voice check server, the received audio signal and the received identifier of the recipient, wherein the voice check server has converted the audio signal to first text determined that the first text matches the received voice check tex, computed a voiceprint of the audio signal, and determined that the computed voiceprint matches a voiceprint stored in a voiceprint database of the voice check server and associated with the transmitted identifier of the recipient; and decrypting, by the recipient computer, the received encrypted file using an encryption key. |
