| Abstract(in English) | In this paper, we propose a method of perceptual encryption and its efficient key management for images presupposing JPEG or motion JPEG compression. Perceptual encryption is a processing technique which makes an image difficult to recognize visually. In comparison with number theory-based encryption methods, perceptual encryption has a high flexibility for the processing such as it enables an image to be compressed after the encryption. The proposed method is a scheme of performing the block-based perceptual encryption, which is suitable for JPEG compression. It is confirmed that the quality when compressing the visually encrypted image generated by the proposed method is almost same as that when compressing the original one. Also, as an efficient key management for the proposed encryption, we consider a scheme using a hash function to generate encryption keys. |
