This paper proposes an encryption-then-compression (ETC)-based copyright- and privacy-protected image trading system. It focuses on image copyright protection, consumer's privacy protection, and compression-friendliness with accepting any fingerprinting techniques. In the system, the ETC is applied to images for visual protection of consumer's privacy, whereas the conventional purpose of ETC techniques does not assume that a trusted third party decompresses an image for digital fingerprinting. With the same system features, the proposed system gives better performances in terms of visual protection, image quality, compression compatibility, and fingerprinting than those of conventional systems.
