A method may include during playback of content, periodically capturing an audio overlay of an audio track of the content, wherein the audio overlay includes an encrypted timestamp associated with a time of creation of the content. The method may also include, during playback of the content: periodically extracting the encrypted timestamp from the audio overlay, continuously decrypting the encrypted timestamp with a public key of a public-private key pair comprising a private key used to encrypt the encrypted timestamp, in order to continuously create a decrypted timestamp, and continuously comparing the decrypted timestamp with a creation time of the content to verify one or more of authorship and authenticity of the content.
