| Abstract: | A simple image scrambling method for image-based authentication (IBA) is proposed and evaluated. The devised scheme may be embedded into any wavelet-based IBA framework to provide mutual authentication with challenge-response architecture. The severe constraints on security, data transmission capability and user friendliness are addressed by the complete system, especially in the wireless environment. Data and application scalability is provided through the JPEG2000 standard and JPIP framework. | ||
