Method and apparatus for the secure storage of audio signals
View Patent ↗In one embodiment, a method, system and apparatus for recording audio is provided so that the recording can be authenticated. The system may be implemented as a central server that is accessed via one or more lines for audio communication, or as a stand-alone unit. The system operates by encrypting communicated data (e.g., audio signals), storing the encrypted information, and providing at least one user with a key that can be used to decrypt the stored information.
1. A method comprising:
receiving, by the central server, audio content data from a first party;
encoding the audio content;
storing, by the central server, the encoded audio content;
determining, by the central server, a key for decoding the encoded audio content;
transmitting the key to the first party;
generating a first access code that can be used to obtain access to the stored encoded audio content; and
transmitting, by the central server, the first access code to the first party.
2. The method of claim 1 , further comprising:
transmitting the key to a second party;
generating a second access code that can be used to obtain access to the encoded audio content; and
transmitting the second access code to a second party, in which the second access code is different than the first access code, and in which the second party is different than the first party.
3. The method of claim 1 , further comprising:
storing the first access code in association with the encoded audio content.
4. The method of claim 1 , wherein the encoded audio content is obtained from a telephone communication between the first party and another party.
5. The method of claim 1 , in which establishing communication comprises:
establishing connection between a calling party and a called party via the internet.
6. The method of claim 1 , in which encoding the audio content comprises:
encrypting, via a cryptographic processor, the audio content.
7. The method of claim 1 , further comprising:
receiving the first access code from the first party;
receiving the key from the first party;
decoding the encoded audio content using the received key; and
transmitting the decoded audio content to the first party.
8. The method of claim 7 , further comprising:
storing, by the central server, an indication that the decoded audio content was transmitted to the first party.
9. The method of claim 7 , further comprising:
verifying, by the central server, the received first access code; and
verifying, by the central server, the received key.
10. The method of claim 1 , in which the first access code comprises a timestamp associated with the audio content.
11. A system comprising:
a processor;
a cryptographic processor in communication with the processor; and
a storage device in communication with the processor, the storage device storing instructions configured to direct the processor to perform a method, the method comprising:
identifying audio content communicated between at least two parties; encoding, via the cryptographic processor, the communicated audio content;
storing the encoded communicated audio content;
determining a key for decoding the encoded communicated audio content;
transmitting the key to a first party of the at least two parties;
generating a first access code that can be used to obtain access to the stored encoded communicated audio content; and
transmitting the first access code to the first party of the at least two parties.
12. The system of claim 11 , the instructions being further configured to direct the processor to:
transmit the key to a second party of the at least two parties;
generate, via the cryptographic processor, a second access code that can be used to obtain access to the encoded communicated data; and
transmit the second access code to a second party of the at least two parties, in which the second access code is different than the first access code, and in which the second party is different than the first party.
13. The system of claim 11 , the instructions being further configured to direct the processor to:
associate the first access code with the encoded communicated audio content.
14. The system of claim 11 , in which establishing communication comprises:
establishing a telephone connection between a calling party and a called party.
15. The system of claim 11 , in which establishing communication comprises:
establishing connection between a calling party and a called party via the internet.
16. The system of claim 11 , in which encoding the communicated audio content comprises:
encrypting, via the cryptographic processor, the communicated audio content.
17. The system of claim 11 , the instructions being further configured to direct the processor to:
receive the first access code from the first party;
receive the key from the first party;
decode, via the cryptographic processor, the encoded communicated audio content using the received key; and
transmit the decoded communicated audio content to the first party.
18. The system of claim 17 , the instructions being further configured to direct the processor to:
store an indication that the decoded communicated audio content has been transmitted to the first party.
19. The system of claim 17 , the instructions being further configured to direct the processor to:
verify the received first access code; and
verify the received key.
20. The system of claim 11 , in which the first access code comprises a timestamp associated with the communicated audio content.
