Abstract

A system and method for identification of inappropriate multimedia content elements are provided. The method includes receiving a request to identify a multimedia content element from a user device; generating at least one signature respective of the received multimedia content element; matching between the at least one of generated signature respective of the multimedia content element and at least one signature of each concept designated as inappropriate; determining whether a match is identified between the at least one of signature generated respective of the multimedia content element and the at least one signature of an inappropriate concept; and preventing the display on a user device of the multimedia content element, upon identification of a match.

Claims

1. A method for identification of inappropriate multimedia content elements, comprising:

receiving a request to identify a multimedia content element from a user device;

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

matching between the at least one generated signature for the received multimedia content element and at least one signature of each of at least one inappropriate concept, wherein each inappropriate concept is a concept that is designated as inappropriate, wherein each of the at least one inappropriate concept is associated with a plurality of multimedia content elements, and includes a reduced cluster of signatures representing the plurality of multimedia content elements, and textual metadata related to the plurality of multimedia content elements;

determining whether a match is identified between the at least one signature generated for the received multimedia content element and the at least one signature of at least one inappropriate concept; and

preventing a display on a user device of the received multimedia content element, upon identification of a match.

2. The method of claim 1, wherein the at least one inappropriate concept is determined based on a set of characteristics of a user of the user device.

3. The method of claim 2, wherein the characteristics of the user of the user device are at least one of:

age, geographic location, religion, and background.

4. The method of claim 1, wherein each inappropriate concept is any of:

retrieved from a data warehouse with its respective at least one signature, received as an input from a user device, and received as an input from a user'"'"'s supervisor'"'"'s device.

5. The method of claim 1, wherein the signatures representing the plurality of multimedia content elements represent responses of one or more neural networks to the plurality of multimedia content elements.

6. The method of claim 1, further comprising:

generating the reduced cluster of signatures by performing a cluster reduction process that comprises reducing a number of signatures of the reduced cluster while remaining a minimal number of signatures to that still identify all of the plurality of multimedia content items.

7. The method of claim 1 comprising generating the at least one signature for received multimedia content by a plurality of at least partially statistically independent computational cores.

8. The method of claim 1, further comprising:

using at least one probabilistic model to determine whether the match is identified.

20. The method of claim 1, wherein each signature is generated by a signature generator system, wherein the signature generator system includes a plurality of computational cores configured to receive a plurality of unstructured data elements, each computational core of the plurality of computational cores having properties that are at least partly statistically independent of other of the computational cores, the properties are set independently of each other core.

9. A non-transitory computer readable medium having stored thereon instructions for causing at least one processing unit to execute a method

for identification of inappropriate multimedia content elements, comprising:

receiving a request to identify a multimedia content element from a user device;

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

matching between the at least one generated signature for the received multimedia content element and at least one signature of each of at least one inappropriate concept, wherein each inappropriate concept is a concept that is designated as inappropriate, wherein each of the at least one inappropriate concept is associated with a plurality of multimedia content elements, and includes a reduced cluster of signatures representing the plurality of multimedia content elements, and textual metadata related to the plurality of multimedia content elements;

determining whether a match is identified between the at least one signature generated for the received multimedia content element and the at least one signature of at least one inappropriate concept; and

preventing a display on a user device of the received multimedia content element, upon identification of a match.

10. A system for removal of an inappropriate concept, comprising:

a network interface configured to receive a request to identify a multimedia content element from a user device;

a processor;

a memory communicatively connected to the processor, wherein the memory contains instructions that, when executed by the processor, configure the system to;

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

match between the at least one generated signature for the received multimedia content element and at least one signature of each of at least one inappropriate concept, wherein each inappropriate concept is a concept that is designated as inappropriate, wherein each of the at least one inappropriate concept ef is associated with a plurality of multimedia content elements, and includes a reduced cluster of signatures representing the plurality of multimedia content elements, and textual metadata related to the plurality of multimedia content elements;

determine whether a match is identified between the at least one signature generated for the received multimedia content element and the at least one signature of at least one inappropriate concept; and

prevent a display on a user device of the received multimedia content element, upon identification of a match.

11. The system of claim 10, wherein the system is communicatively connected to a data warehouse for maintaining the at least one inappropriate concept with its respective at least one signature.

12. The system of claim 10, wherein each inappropriate concept is any of:

retrieved from the data warehouse with its respective at least one signature, received as an input from a user device, and received as an input from the user'"'"'s supervisor device.

13. The system of claim 12, wherein the at least one signature for the received multimedia content element is generated by a signature generator system (SGS), wherein the SGS is communicatively connected to the system.

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

generate the reduced cluster of signatures by performing a cluster reduction process that comprises reducing a number of signatures of the reduced cluster while remaining a minimal number of signatures to that still identify all of the plurality of multimedia content items.

15. The system of claim 11, wherein the signatures representing the plurality of multimedia content elements represent responses of one or more neural networks to the plurality of multimedia content elements.

16. The system of claim 10, wherein the system is further configured to use at least one probabilistic model to match between the signatures.

17. The system of claim 10, wherein the received 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, and portions thereof.

18. The system of claim 10, wherein the at least one inappropriate concept is determined based on a set of characteristics of a user of the user device.

19. The system of claim 18, wherein the user'"'"'s characteristics are at least one of:

age, geographic location, religion, and background.
