System and method for communicating confidential messages

A method of recording messages comprising:

• accessing, with a processor, encrypted audio data associated with a call and stored in a first file structured in accordance with a file format that defines a first portion and a second portion, the encrypted audio data encrypted with one or more public keys identified based on one or more recipient identifiers, the recipient identifiers received from a caller associated with the audio data and identifying one or more recipients of the call, wherein decoy audio data is stored in the first portion of the first file and the encrypted audio data is stored in the second portion of the first file, the decoy audio data indicating a confidential status of the second file;
• decrypting, with the processor, the encrypted audio data;
• and
• generating, with the processor, a second file that includes the decrypted audio data, wherein the second file is structured according to the file format, and wherein the decrypted audio data is stored in the first portion of the second file.

A device for recording messages comprising:

• a memory operable to store processor instructions;
• and
• a processor operable to:
• record audio data associated with a call in a first file structured in accordance with a file format that defines a first portion and a second portion, wherein the audio data is recorded in the first portion of the first file;
• receive one or more recipient identifiers from a caller associated with the call, the recipient identifiers identifying one or more recipients of the audio data;
• identify, based on the one or more recipient identifiers received from the caller, one or more public keys associated with the one or more recipients of the audio data;
• encrypt the audio data stored in the first portion of the first file based on the identified one or more public keys;
• and
• generate a second file structured according to the file format that includes decoy audio data in the first portion of the second file and the encrypted audio data in the second portion of the second file, the decoy audio data indicating a confidential status of the second file.
