Abstract
An image pickup apparatus certifies unchanged image data by photographing a person using the image pickup apparatus. Two steps are carried out with the image pickup apparatus, coding image data and enciphering the coded image data, which includes changing the original data to encryption data. The enciphering also includes adding a watermark to the coded data. The coding of the image data and enciphering of the coded data are performed before the coded data is stored in a medium or is transferred to another device.

1-19 (Canceled).
A digital image processing system comprising:
- an image input unit for receiving an optical image;
- and
- an image processing device connectable to the image input unit,
- wherein the image processing device further comprises:
- an image code device for transforming the optical image to digital image data;
- a processor;
- a memory;
- and
- a storage device,
- wherein said processor ciphers the digital image data to provide encrypted digital image data before storing the digital image data into said storage device and transfers the encrypted digital image data to said storage device,
- wherein said memory includes information for indicating a relation among the encrypted digital image data, encryption method which is used for ciphering the digital image data and encryption key which is used for deciphering of the encrypted digital image data.
A digital image processing system comprising:
- a plurality of image pick up apparatuses;
- and
- a network connected the plurality of the image pick up apparatuses each other,
- wherein some of the image pick up apparatuses comprise:
- an image input unit for receiving an optical image;
- an image code device for transforming the optical image to digital image data;
- a processor;
- a memory;
- and
- a storage device,
- wherein one of the plurality of image pick up apparatuses sends digital image data to the other one of the plurality of image pickup apparatuses via the network,
- wherein said processor of the other one of the plurality of image pick up apparatuses ciphers the digital image data, which are sent from the one of the plurality of image pick up apparatuses, to provide encrypted digital image data before storing the digital image data into said storage device and transfers the encrypted digital image data to said storage device,
- wherein said memory includes information for indicating a relation among the encrypted digital image data, encryption method which is used for ciphering the digital image data an encryption key which is used for deciphering of the encrypted digital image data.
