Patent Images
1. An image processing apparatus having an image reading unit which reads image information from a document to obtain image data, comprising:
- an encryption key extracting unit which extracts encryption key information from said document having said encryption key information;
a key information storing unit which stores said encryption key information extracted by said encryption key extracting unit; and
an encrypting unit which encrypts said image data on the basis of said encryption key information.

Abstract
An encryption key extracting unit extracts encryption key information from an encryption key sheet on which an encryption key has been printed in a readable format. A key information storing unit stores the extracted encryption key information. An encrypting unit encrypts image data read by a reading unit from a transmission original on the basis of the encryption key information. Processes for encrypting the read image data on the basis of a public key encryption system and transmitting the encrypted data are simplified.
