System and method for audio content verification
Methods and systems for determining a context of recorded audio information and for verifying authenticity of an audio recording are disclosed. Exemplary methods can include mixing signals from the audio communication with metadata modulated using a carrier wave.
1. A system for verifying audio information, the system comprising:
a telephony switch system;
an audio signature generator; and
an audio signal mixer,
wherein the audio signature generator generates an identifier,
wherein the telephony switch system connects the audio signature generator to a communication, and
wherein the audio mixer receives audio information from at least one communication device and information from the audio signature generator to form a mixed signal.
2. The system of claim 1 , wherein the identifier comprises a unique identification corresponding to a context.
3. The system of claim 1 , wherein the audio signature generator generates modulated metadata for the communication.
4. The system of claim 3 , wherein the modulated metadata is formed using a carrier wave.
5. The system of claim 4 , wherein a frequency of a modulated carrier wave is between about 18 kHz and about 20 kHz.
6. The system of claim 3 , further comprising a database comprising information corresponding to metadata.
7. The system of claim 6 , wherein the metadata comprises the identifier.
8. The system of claim 6 , wherein the metadata comprises an acoustic hash.
9. The system of claim 6 , wherein the metadata comprises a time sequence identification.
10. An electronic communication method comprising the steps of:
initiating an audio communication;
generating an identifier using an audio signature generator;
creating metadata comprising the identifier;
mixing signals from the audio communication with modulated metadata to create mixed signal information; and
storing information corresponding to the metadata.
11. The method of claim 10 , wherein the identifier corresponds to a communication context.
12. The method of claim 10 , wherein the steps of mixing audio signals, creating metadata, and storing are repeated a number of times during the audio communication.
13. The method of claim 10 , further comprising transmitting video information with the audio communication.
14. The method of claim 10 , wherein the metadata comprises the identifier, a time offset code, and an acoustic hash.
15. The method of claim 10 , further comprising a step of validating a recording.
16. The method of claim 15 , wherein the step of validating comprises extracting a recorded identifier from information to be validated.
17. The method of claim 16 , wherein, if the recorded identifier comprises a valid identifier, then retrieving information corresponding to the metadata from the database.
18. The method of claim 17 , wherein the step of validating comprises generating metadata for the recording.
19. The method of claim 15 , wherein the step of validating comprises comparing metadata.
20. A system for verifying audio information, the system comprising:
a telephony switch;
an audio signature generator;
an audio signal mixer;
a database; and
a verification engine,
wherein the audio signature generator generates an identifier,
wherein the telephony switch connects the audio signature generator to a communication,
wherein a conference server receives audio information from at least one communication device and information from the audio signature generator to form a mixed signal,
wherein the database stores the identifier and information corresponding to the metadata, and
wherein the verification engine verifies an authenticity of a recording.
