Image and optical mark scanner with encryption
First Claim
Patent Images
1. A scanner comprising:
- a scanning head to scan data from a physical medium;
an encryption algorithm for encrypting the scanned data;
a processor operable to use the encryption algorithm to encrypt the data scanned by the scanning head, wherein the processor is operable to encrypt the scanned data substantially immediately after at least some of the data scanned by the scanning head; and
an output port to output the data encrypted by the processor.

Abstract
A scanner for scanning images and optical marks with optical mark recognition (OMR) and encryption is disclosed. A scanning system may include a scanning head configured to read documents comprising characters, marks, and images. The scanning system may include an encryption algorithm for encrypting the scanned data, a processor to use the encryption algorithm to encrypt the data scanned by the scanning head, and an output port to output the data encrypted by the processor. The scanner may encrypt the scanned data substantially immediately after at least some of the data scanned by the scanning head.

17. A method comprising:
-
scanning data from a document with a scanner;
using an encryption algorithm stored on the scanner to encrypt the scanned data in the scanner, wherein the scanner is configured to encrypt the scanned data substantially immediately after at least some data from the document is scanned; and
outputting the encrypted data from the scanner via an output port on the scanner. - View Dependent Claims (18, 19, 20)
