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, comprising:

generating a security code at a server as part of a registration process;

sending the security code from the server;

after sending the security code, receiving data at the server including an encryption of text scanned from a rendered document, wherein the encryption of text is encrypted using the sent security code; and

decrypting the scanned text included in the received data using the security code.

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

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

4. The method of claim 1 wherein receiving the data including the encryption of text includes receiving the data including the encryption of text with return address information replaced so to not identify a device that captured the text from the rendered document.

5. The method of claim 2 wherein the session key includes information about a capture.

6. The method of claim 2 wherein the session key includes information about a scanning device.

7. The method of claim 3 wherein the public/private key pair includes information about a capture.

8. The method of claim 3 wherein the public/private key pair includes information about a scanning device.

9. The method of claim 5 wherein the information about the capture includes biometric information.

10. The method of claim 6 wherein the information about the scanning device is stored at least partially in hardware.

11. The method of claim 7 wherein the information about the capture includes biometric information.

12. The method of claim 8 wherein the information about the scanning device is stored at least partially in hardware.

13. A method comprising:

receiving, at a scanner, a security code provided as part of a registration process;

capturing at least a portion of a rendered document using the scanner;

encrypting the captured information based on the security code using the scanner; and

sending the encrypted information from the scanner.

14. The method of claim 13 wherein the scanner comprises a hand-held scanning optical scanning device.

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

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

17. The method of claim 14 wherein sending the encrypted information includes at least partially wirelessly sending the encrypted information.

18. The method of claim 14, wherein sending the encrypted information comprises replacing a return address for the encrypted information so to not identify the scanner.

19. The method of claim 15 wherein the session key includes information about a capture.

20. The method of claim 15 wherein the session key includes information identifying the scanner.

21. The method of claim 16 wherein the public/private key pair includes information about the capture.

22. The method of claim 16 wherein the public/private key pair includes information identifying the scanner.

23. The method of claim 19 wherein the information about the capture includes biometric information.

24. The method of claim 20 wherein the information identifying the scanner is stored at least partially in hardware.

25. The method of claim 21 wherein the information about the capture includes biometric information.

26. The method of claim 22 wherein the information identifying the scanner is stored at least partially in hardware.

27. A device, comprising:

a processor;

a computer program configured to, upon execution, cause the processor to perform functions comprising;

receiving a security code provided as part of a registration process;

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 based on the security code; and

sending the encrypted information.

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

29. The device of claim 28 wherein encrypting the generated scan information includes encrypting the generated scan information using a session key.

30. The device of claim 28 wherein encrypting the generated scan information includes encrypting the generated scan information using a public/private key pair.

31. The device of claim 28 wherein sending the encrypted information comprises replacing a return address for the encrypted information so to not identify the device.

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

33. The device of claim 29 wherein the session key includes scanner identification information.

34. The device of claim 30 wherein the public/private key pair includes scanner information.

35. The device of claim 30 wherein the public/private key pair includes identification information.

36. The device of claim 32 wherein the scanner information includes biometric information.

37. The device of claim 33 wherein the scanner identification information is stored at least partially in hardware.

38. The device of claim 34 wherein the scanner information includes biometric information.

39. The device of claim 35 wherein the scanner identification information is stored at least partially in hardware.

40. The device of claim 39 wherein sending the encrypted information includes at least partially wirelessly sending the encrypted information.

41. An apparatus, comprising:

means for receiving a security code provided as part of a registration process;

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

means for encrypting the generated scan information using the security code; and

means for sending the encrypted information.

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

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

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

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

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

47. The apparatus of claim 44 wherein the public/private key pair includes scanner information.

48. The apparatus of claim 44 wherein the public/private key pair includes scanner identification information.

49. The apparatus of claim 45 wherein scanner information includes biometric information.

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

51. The apparatus of claim 47 wherein scanner information includes biometric information.

52. The apparatus of claim 48 wherein the scanner identification information is stored at least partially in hardware.
