However, a digital image taken by the above digital camera device can be easily changed by using an image composition program or the like, so that the copyright of the photographer can be protected or the image can be protected when the image is taken. There was a drawback that it was difficult to prevent subsequent tampering.

As a method for solving the above-mentioned drawback, image data photographed by a digital camera device is temporarily transferred to a computer system, and user identification information is added to the image data using a program operating on the computer system. To convert the image data into image data with identification information.

[0005] Technologies that can be used for such purposes include digital watermarking technologies such as Digimarc's Picture Marc.
An electronic signature name technology represented by the method of USP 4,405,829 of RSA Data Sscurity is known and has already been put to practical use. The digital watermarking technique is a method of embedding identification information of a user in an image itself in a form that cannot be recognized by human eyes, and is a technique mainly used for the purpose of copyright protection.

On the other hand, the digital signature technology is a system in which both the characteristics of the image and the identification information of the user are encoded and added to the image data, and is mainly used for the purpose of preventing tampering.

[0007] However, in the above solution,
Since the process of taking a photo and the process of adding identification information to image data are independent, user operations must be complicated, and identification information is added to the photographer and image data. Is not equipped with a mechanism to guarantee that the person who made the photo is the same person, and for the purpose of obtaining a digital image with the identification information of the photographer as a creative act of taking a digital photograph Had a problem of lack of reliability.

[0008] The present invention has been made in view of the above-mentioned problems, and the object thereof is to provide a digital camera with a digital camera.
An object of the present invention is to provide a digital camera device capable of creating a digital image with identification information to which identification information of a photographer is added without requiring a subsequent operation process.
