Abstract

A method for processing multimedia content for authentication and authenticating the multimedia content includes registering a scheduled event, creating a mapping between the scheduled event and a registrant of the scheduled event and in response to creating the mapping between the scheduled event and the registrant, issuing a request to add a block in a blockchain for the mapping. The method also includes in response to the request, receiving, a block identifier, generating a start code for one or more modulation schemes based on the block identifier, receiving multimedia content generated based on the scheduled event and modifying the multimedia content based on the one or more modulation schemes for distribution of the multimedia content.

First claim

What is claimed is:

1. A method, comprising:
registering, by a processor, a scheduled event;
creating, by the processor, a mapping between the scheduled event and a registrant of the scheduled event;
in response to creating the mapping between the scheduled event and the registrant, issuing, by the processor, a request to add a block in a blockchain for the mapping;
in response to the request, receiving, by the processor, a block identifier;
generating, by the processor, a start code for one or more modulation schemes based on the block identifier;
receiving, by the processor, multimedia content generated based on the scheduled event;
modifying, by the processor, the multimedia content based on the one or more modulation schemes for distribution of the multimedia content;
receiving, by the processor, multimedia content under test, perceived to be associated with the scheduled event;
obtaining, by the processor, an index to the block in the blockchain based on the scheduled event;
requesting, by the processor, one or more modulation schemes from the blockchain based on the index; and
checking, by the processor, for matches between one or more modulation schemes of the multimedia content under test and the one or more modulation schemes from the blockchain.

2. The method according to claim 1 , wherein the scheduled event is a conference call, a press conference or a phone call.

3. The method according to claim 1 , wherein the one or more modulation schemes include audio frequency modulation.

4. The method according to claim 3 , wherein the audio frequency modulation changes periodically.

5. The method according to claim 1 , wherein the one or more modulation schemes include video modulation.

6. The method according to claim 5 , wherein the video modulation includes changes in eye color for actors in the multimedia content.

7. The method according to claim 1 , wherein the one or more modulation schemes are generated using artificial intelligence.

8. The method according to claim 1 , wherein the multimedia content under test is a deepfake of the multimedia content.

9. The method according to claim 1 , wherein image signal processing and audio digital signal processing are used for checking for matches between the one or more modulation schemes of the multimedia content under test and the one or more modulation schemes from the blockchain.

10. The method according to claim 1 , wherein in response to determining that matches do not exist between the one or more modulation schemes of the multimedia content under test and the one or more modulation schemes from the blockchain, providing notice, by the processor, that the multimedia content under test is not the multimedia content generated based on the scheduled event.

11. The method according to claim 1 , wherein in response to determining that matches exist between the one or more modulation schemes of the multimedia content under test and the one or more modulation schemes from the blockchain, providing notice, by the processor, that the multimedia content under test is the multimedia content generated based on the scheduled event.

12. A system, comprising:
a processor; and
a memory coupled with and readable by the processor and having stored therein a set of instructions which, when executed by the processor, causes the processor to:
register a scheduled event;
create a mapping between the scheduled event and a registrant of the scheduled event;
in response to creating the mapping between the scheduled event and the registrant, issue a request to add a block in a blockchain for the mapping;
in response to the request, receive a block identifier;
generate a start code for one or more modulation schemes based on the block identifier;
receive multimedia content generated based on the scheduled event;
modify the multimedia content based on the one or more modulation schemes for distribution of the multimedia content;
receive multimedia content under test, perceived to be associated with the scheduled event;
obtain an index to the block in the blockchain based on the scheduled event;
request one or more modulation schemes from the blockchain based on the index; and
check for matches between one or more modulation schemes of the multimedia content under test and the one or more modulation schemes from the blockchain.

13. The system according to claim 12 , wherein the scheduled event is a conference call, a press conference or a phone call.

14. The system according to claim 12 , wherein the one or more modulation schemes are generated using artificial intelligence.

15. The system according to claim 12 , wherein the multimedia content under test is a deepfake of the multimedia content.

16. The system according to claim 12 , wherein the one or more modulation schemes include video modulation.

17. The system according to claim 16 , wherein the video modulation includes changes in eye color for actors in the multimedia content.

18. A non-transitory computer readable medium comprising microprocessor executable instructions that, when executed by the microprocessor, perform the following functions:
register a scheduled event;
create a mapping between the scheduled event and a registrant of the scheduled event;
in response to creating the mapping between the scheduled event and the registrant, issue a request to add a block in a blockchain for the mapping;
in response to the request, receive a block identifier;
generate a start code for one or more modulation schemes based on the block identifier;
receive multimedia content generated based on the scheduled event;
modify the multimedia content based on the one or more modulation schemes for distribution of the multimedia content;
receive multimedia content under test, perceived to be associated with the scheduled event;
obtain an index to the block in the blockchain based on the scheduled event;
request one or more modulation schemes from the blockchain based on the index; and
check for matches between one or more modulation schemes of the multimedia content under test and the one or more modulation schemes from the blockchain.

19. The non-transitory_computer readable medium according to claim 18 , wherein the scheduled event is a conference call, a press conference or a phone call.

20. The non-transitory_computer readable medium according to claim 18 , wherein the one or more modulation schemes are generated using artificial intelligence.
