| Original document(30 pages) 中文版 |
Image processing apparatus receives an original document on which confidential information is written, and outputs an image upon converting it in a form which allows only a specific person or terminal to read the contents. The original image data read by a reading unit is stored in a memory. Area definition information defining an entry area in the original and encryption key specifying information specifying an encryption key are extracted from a copy-forgery-inhibited pattern from the original image data stored in the memory. The image data in the entry area is encrypted by using the specified encryption key. The image data in the RAM is updated and output by storing the information obtained by encryption as image data in the corresponding entry area in the image data. |
