Abstract
In this paper a camera system with image encryption is proposed, which integrates image acquisition, image encryption and image compression into the camera system. In contrast to conventional camera just acquiring image and compressing it, this camera system gathers original image data coming from outside scene with CCD, then compresses and encrypts it by three-dimensional Lorenz chaos sequence XOR original image data in DSP chipset. Finally the secured image data are stored in the camera or transmitted via network on the system. We designed the prototype camera based on the DM6446. Our preliminary experiment shows that the new camera system can make up for the deficiency of current camera and effectively protect the secret image or privacy image preventing from stealing and peeking by unauthorized users.
