Abstract
Techniques for authentication of digital recordings are provided. An element of encrypted data is output in a recording environment. The element of encrypted data, embedded in a digital recording comprising at least one of audio data and image data captured in the recording environment, is extracted. A decrypted value is generated based on a private key and the first element of encrypted data, and the first decrypted value and a stored value associated with a first element of the digital recording are compared. The digital recording is authenticated based on the first decrypted value substantially matching the stored value.
