ABSTRACT:
A digital camera for embedding authentication information to detect the identity of a photographed image into an image. By supplying the authentication information integrally with image data, the verifier is enabled to verify the image data without saving the authentication information. Particularly, by converting the light inputted through an optical system to an electric signal, a CCD outputs an analog signal of an image which is converted to a digital signal. In response to the digital signal of the image, a digital camera having a region dividing unit divides the digital image into first and second regions. Authentication information is generated from data in the first region, which information is then encrypted. The encrypted authentication information is embedded into the second image region. The first and second image regions are then combined.
