Abstract

A method and system for creating a database of multimedia content elements assigned to users are provided. The method comprises receiving at least one parameter identifying a user; receiving at least one multimedia content element from a user device; generating at least one signature to the at least one multimedia content element; searching for the existence of the at least multimedia content element in a database using the least one generated signature to determine whether each of the at least one multimedia content element is an existing multimedia content element or a non-existing multimedia content element; and generating a unique identifier using the at least one parameters for each non-existing multimedia content element; assigning the generated unique identifier to its respective non-existing multimedia content element; and storing each of the non-existing multimedia content elements and their respective unique identifiers in the database.

Claims

1. A method for creating a database of multimedia content elements assigned to users, comprising:

receiving at least one parameter identifying a user;

receiving at least one multimedia content element from a user device;

generating at least one signature to the received at least one multimedia content element;

searching for the existence of the at least one multimedia content element in a database using the least one generated signature to determine whether each of the at least one multimedia content element is an existing multimedia content element or a non-existing multimedia content element;

generating, based on the at least one parameter, a unique identifier for each non-existing multimedia content element;

assigning the generated unique identifier to its respective non-existing multimedia content element; and

storing the non-existing multimedia content elements and their respective unique identifiers in the database.

2. The method of claim 1, wherein the unique identifier is generated using a random function computed over at least one of:

the at least one parameter and the at least one parameter.

3. The method of claim 2, further comprising:

generating at least one new signature for each non-existing multimedia content element and the unique identifier; and

storing each of the non-existing multimedia content elements and their respective new signatures in the database.

4. The method of claim 2, further comprising:

creating a watermark using the unique identifier generated for each non-existing multimedia content element; and

embedding the watermark in its respective non-existing multimedia content element.

5. The method of claim 1, further comprising:

generating a notification upon identification of an existing multimedia content element in the database.

6. The method of claim 1, wherein the multimedia content element is at least one of:

an image, graphics, a video stream, a video clip, an audio stream, an audio clip, a video frame, a photograph, images of signals, combinations thereof, and portions thereof.

7. A system for creating a database of multimedia content elements assigned to users, comprising:

a network interface to allow at least a connection to the database;

a processor; and

a memory coupled to the processor, the memory contains instructions that when executed by the processor cause the system to;

receive at least one parameter identifying a user;

receive at least one multimedia content element from a user device;

generate at least one signature to the received at least one multimedia content element;

search for the existence of the at least one multimedia content element in a database using the least one generated signature to determine whether each of the at least one multimedia content element is an existing multimedia content element or a non-existing multimedia content element;

generate, based on the at least one parameter, a unique identifier for each non-existing multimedia content element;

assign the generated unique identifier to its respective non-existing multimedia content element; and

store the non-existing multimedia content elements and their respective unique identifiers in the database.

8. The system of claim 7, wherein the unique identifier is generated using a random function computed over at least one of:

the at least one parameter and the at least one parameter.

9. The system of claim 8, wherein the system is further configured to:

generate at least one new signature for the each non-existing multimedia content element and the unique identifier; and

store each of the non-existing multimedia content elements and their respective new signatures in the database.

10. The system of claim 8, wherein the system is further configured to:

create a watermark using the unique identifier generated for each non-existing multimedia content element; and

embed the watermark in its respective non-existing multimedia content element.

11. The system of claim 8, wherein the system is further configured to:

generate a notification upon identification of an existing multimedia content element in the database.

12. The system of claim 7, wherein the multimedia content element is at least one of:

an image, graphics, a video stream, a video clip, an audio stream, an audio clip, a video frame, a photograph, images of signals, combinations thereof, and portions thereof.

13. A non-transitory computer readable medium having stored thereon instructions for causing one or more processing units to execute a method, the method comprising:

receiving at least one parameter identifying a user;

receiving at least one multimedia content element from a user device;

generating at least one signature to the received at least one multimedia content element;

searching for the existence of the at least one multimedia content element in a database using the least one generated signature to determine whether each of the at least one multimedia content element is an existing multimedia content element or a non-existing multimedia content element;

generating, based on the at least one parameter, a unique identifier for each non-existing multimedia content element;

assigning the generated unique identifier to its respective non-existing multimedia content element; and

storing the non-existing multimedia content elements and their respective unique identifiers in the database.
