Abstract

A system, method, and computer program product are provided for preventing data loss associated with an image. In use, an image is identified, and it is determined whether the image includes predetermined data. In addition, an action is performed based on the determination, for preventing data loss.

Claims

1-22. -22. (canceled)

23. A method, comprising:

identifying an image included within a communication;

extracting textual data from the image;

determining whether the image includes predetermined data by comparing a representation of a portion of the textual data with the predetermined data; and

performing an action based on the determination, wherein the action includes preventing a subsequent communication of the image based on determining that the image includes the predetermined data.

24. The method of claim 23, wherein the action further includes quarantining the image based on determining that the image includes the predetermined data.

25. The method of claim 23, wherein extracting textual data from the image comprises performing an optical character recognition (OCR) procedure on the image.

26. The method of claim 23, wherein extracting textual data from the image comprises performing an intelligent character recognition (ICR) procedure on the image.

27. The method of claim 23, wherein the extracting of the textual data from the image is performed utilizing at least one neural network.

28. The method of claim 23, wherein preventing subsequent communication of the image includes preventing a subsequent electronic mail message, which attaches the image, from propagating in a network.

29. The method of claim 23, wherein the image is a screenshot.

30. The method of claim 23, wherein the predetermined data includes data determined to be associated with confidential information.

31. The method of claim 23, wherein the image is identified in response to communication of the image over a network.

32. The method of claim 23, wherein the image is stored on a device.

33. The method of claim 23, wherein the image is identified during a system scan.

34. The method of claim 23, wherein the image is included as an attachment in an electronic mail message.

35. The method of claim 23, wherein the action further includes at least one of:

notifying an administrator;

notifying a management team;

notifying a sender of the image; and

notifying a recipient of the image.

36. The method of claim 23, wherein the representation of the portion of the textual data is generated by fingerprinting at least a portion of the textual data extracted from the image.

37. The method of claim 36, wherein fingerprinting the portion of the textual data includes hashing of the at least a portion of the textual data.

38. The method of claim 36, wherein the image is determined to include the predetermined data, if the fingerprinted textual data matches the predetermined data.

39. The method of claim 23, wherein the identifying, determining, and performing are performed at one or more of a gateway, a mail server, a web server, and a file transfer protocol server.

40. The method of claim 23, further comprising allowing communication of the image, if it is determined that the image does not include the predetermined data.

43. The system of claim 39, further comprising memory coupled to the processor via a bus.

41. A computer program product embodied on a non-transitory computer readable medium for performing operations, comprising:

identifying an image included within a communication;

extracting textual data from the image;

determining whether the image includes predetermined data by comparing a representation of a portion of the textual data with the predetermined data; and

performing an action based on the determination, wherein the action includes preventing a subsequent communication of the image based on determining that the image includes the predetermined data.

42. A system, comprising:

a processor, wherein the system is configured for;

identifying an image included within a communication;

extracting textual data from the image;

determining whether the image includes predetermined data by comparing a representation of a portion of the textual data with the predetermined data; and

performing an action based on the determination, wherein the action includes preventing a subsequent communication of the image based on determining that the image includes the predetermined data.
