Decoding of encrypted file

A system comprising:

• a recipient computer of a recipient;
• and a computer-readable storage medium storing instructions executable by the recipient computer, implement a method for decoding an encrypted file, said method comprising:
• extracting, by the recipient computer, an encoded address from a filename of the encrypted file, wherein the recipient computer previously received the encrypted file from a sender computer of a sender, 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;
• 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, by the recipient computer, an audio signal from a reading aloud by the prompted recipient of the displayed voice check text;
• and
• receiving, by the recipient computer from the server computer, an identifier of the recipient;
• transmitting, by the recipient computer to a server computer comprising a voice check server, the received audio signal and the received identifier of the recipient;
• receiving, by the recipient computer from the voice check server after the voice check server had received and validated the transmitted audio signal and identifier of the recipient, an encryption key previously used to generate the encrypted file;
• and
• decrypting, by the recipient computer, the received encrypted file using the received encryption key.

A non-transitory storage medium comprising instructions executable by a recipient computer of a recipient, implement a method for decoding an encrypted file, said method comprising:

• extracting, by the recipient computer, an encoded address from a filename of the encrypted file, wherein the recipient computer previously received the encrypted file from a sender computer of a sender, 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;
• 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, by the recipient computer, an audio signal from a reading aloud by the prompted recipient of the displayed voice check text;
• and
• receiving, by the recipient computer from the server computer, an identifier of the recipient;
• transmitting, by the recipient computer to a server computer comprising a voice check server, the received audio signal and the received identifier of the recipient;
• receiving, by the recipient computer from the voice check server after the voice check server had received and validated the transmitted audio signal and identifier of the recipient, an encryption key previously used to generate the encrypted file;
• and
• decrypting, by the recipient computer, the received encrypted file using the received encryption key.
