Content with ultrasonic signature for verification of authorship
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.
1 . A method comprising:
during creation of content, encrypting a timestamp associated with a time of creation of the content with a private key of a public-private key pair comprising a published public key to create an encrypted timestamp; and
during creation of the content, periodically overlaying the encrypted timestamp in an audio track of the content.
2 . The method of claim 1 , wherein periodically overlaying the encrypted timestamp in the audio track of the content comprises periodically overlaying the encrypted timestamp in an ultrasonic frequency of the audio track of the content.
3 . The method of claim 1 , wherein the content comprises content including audio.
4 . The method of claim 1 , wherein the content comprises recorded content.
5 . The method of claim 1 , wherein the content comprises live-broadcast content.
6 . A method comprising:
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;
during playback of the content, periodically extracting the encrypted timestamp from the audio overlay;
during playback of the content, 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
during playback of the content, continuously comparing the decrypted timestamp with a creation time of the content to verify one or more of authorship and authenticity of the content.
7 . The method of claim 6 , wherein the encrypted timestamp is overlaid in an ultrasonic frequency of the audio track of the content.
8 . The method of claim 6 , wherein the content comprises content including audio.
9 . The method of claim 6 , wherein the content comprises recorded content.
10 . The method of claim 6 , wherein the content comprises live-broadcast content.
11 . An article of manufacture comprising:
a non-transitory computer readable medium; and
computer-executable instructions carried on the computer readable medium, the instructions readable by a processor, the instructions, when read and executed, for causing the processor to:
during creation of content, encrypt a timestamp associated with a time of creation of the content with a private key of a public-private key pair comprising a published public key to create an encrypted timestamp; and
during creation of the content, periodically overlay the encrypted timestamp in an audio track of the content.
12 . The article of claim 11 , wherein periodically overlaying the encrypted timestamp in the audio track of the content comprises periodically overlaying the encrypted timestamp in an ultrasonic frequency of the audio track of the content.
13 . The article of claim 11 , wherein the content comprises content including audio.
14 . The article of claim 11 , wherein the content comprises recorded content.
15 . The article of claim 11 , wherein the content comprises live-broadcast content.
16 . An article of manufacture comprising:
a non-transitory computer readable medium; and
computer-executable instructions carried on the computer readable medium, the instructions readable by a processor, the instructions, when read and executed, for causing the processor to:
during playback of content, periodically capture 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;
during playback of the content, periodically extract the encrypted timestamp from the audio overlay;
during playback of the content, continuously decrypt 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
during playback of the content, continuously compare the decrypted timestamp with a creation time of the content to verify one or more of authorship and authenticity of the content.
17 . The article of claim 16 , wherein the encrypted timestamp is overlaid in an ultrasonic frequency of the audio track of the content.
18 . The article of claim 16 , wherein the content comprises content including audio.
19 . The article of claim 16 , wherein the content comprises recorded content.
20 . The article of claim 16 , wherein the content comprises live-broadcast content.
