Abstract

A facility for securing text captured from a rendered document is described. The facility receives data including an encryption of text captured from a rendered document. The facility decrypts the captured text included in the received data.

Claims

1. A method in a computing system for securing text captured form a rendered document, comprising:

receiving data including an encryption of text captured from a rendered document; and

decrypting the captured text included in the received data.

2. The method of claim 1 wherein the decrypting includes decrypting using a session key.

3. The method of claim 2 wherein the session key includes information about a user performing a capture.

4. The method of claim 3 wherein information about a user performing a capture includes biometric information.

5. The method of claim 2 wherein the capture is performed using a scanning device, and wherein the session key includes information identifying the scanning device.

6. The method of claim 5 wherein the information identifying the scanning device is stored at least partially in hardware within the scanning device.

7. The method of claim 1 wherein the decrypting includes decrypting using a public/private key pair.

8. The method of claim 7 wherein the public/private key pair includes information about a user performing a capture.

9. The method of claim 8 wherein the information about a user performing a capture includes biometric information.

10. The method of claim 7 wherein the capture is performed using a scanning device, and wherein the public/private key pair includes information identifying the scanning device.

11. The method of claim 10 wherein the information identifying the scanning device is stored at least partially in hardware within the scanning device.

12. The method of claim 1 wherein receiving includes receiving the encrypted information without any source network address information.

13. A method comprising:

capturing at least a portion of a rendered document;

encrypting the captured information; and

sending the encrypted information to a remote server.

14. The method of claim 13 wherein the capturing is performed using a hand-held scanning optical scanning device.

15. The method of claim 14 wherein the encrypting includes encrypting using a session key.

16. The method of claim 15 wherein the session key includes information about a user performing the capture.

17. The method of claim 16 wherein the information about a user performing the capture includes biometric information.

18. The method of claim 15 wherein the capture is performed using a scanning device, and wherein the session key includes information identifying the scanning device.

19. The method of claim 18 wherein the information identifying the scanning device is stored at least partially in hardware within the scanning device.

20. The method of claim 14 wherein the encrypting includes encrypting using a public/private key pair.

21. The method of claim 20 wherein the public/private key pair includes information about a user performing the capture.

22. The method of claim 21 wherein the information about the user performing the capture includes biometric information.

23. The method of claim 20 wherein the public/private key pair includes information identifying the scanning device.

24. The method of claim 23 wherein the information identifying the scanning device is stored at least partially in hardware within the scanning device.

25. The method of claim 14 wherein the sending includes at least partially wirelessly sending the encrypted information to the remote server.

26. The method of claim 14, further comprising, before sending the encrypted information, stripping the encrypted information of source address information.

27. A computer program product residing in a hand-held scanner device including a processor, the computer program product performing a method comprising:

generating scan information based on a scan of at least a portion of at least one of a paper or displayed document;

encrypting the generated scan information; and

sending the encrypted information to a remote server.

28. The method of claim 27 wherein the generated scan information includes optical scan information.

29. The method of claim 28 wherein the encrypting includes encrypting using a session key.

30. The method of claim 29 wherein the session key includes scanner user information.

31. The method of claim 30 wherein scanner user information includes user biometric information.

32. The method of claim 29 wherein the session key includes scanner identification information.

33. The method of claim 32 wherein the scanner identification information is stored at least partially in hardware within a scanner.

34. The method of claim 28 wherein encrypting includes encrypting using a public/private key pair.

35. The method of claim 34 wherein the public/private key pair includes scanner user information.

36. The method of claim 35 wherein the scanner user information includes user biometric information.

37. The method of claim 34 wherein the public/private key pair includes scanner identification information.

38. The method of claim 37 wherein the scanner identification information is implemented at least partially in hardware within a scanner.

39. The method of claim 38 wherein the sending includes at least partially wirelessly sending the encrypted information to the remote server.

40. The method of claim 28 wherein the sending includes sending the encrypted information includes stripping the encrypted information of original address information.

41. A hand-held scanner apparatus comprising:

a component for generating scan information based on a scan of at least a portion of at least one of a paper or displayed document;

a component for encrypting the generated scan information; and

a component for sending the encrypted information to a remote server.

42. The apparatus of claim 41 wherein the generated scan information includes optical scan information.

43. The apparatus of claim 42 wherein the component for encrypting encrypts using a session key.

44. The apparatus of claim 43 wherein the session key includes scanner user information.

45. The apparatus of claim 44 wherein scanner user information includes user biometric information.

46. The apparatus of claim 43 wherein the session key includes scanner identification information.

47. The apparatus of claim 46 wherein the scanner identification information is implemented at least partially in hardware.

48. The apparatus of claim 42 wherein the component for encrypting encrypts using a public/private key pair.

49. The apparatus of claim 48 wherein the public/private key pair includes scanner user information.

50. The apparatus of claim 49 wherein scanner user information includes user biometric information.

51. The apparatus of claim 48 wherein the public/private key pair includes scanner identification information.

52. The apparatus of claim 51 wherein the scanner identification information is implemented at least partially in hardware within a scanner.
