Outline of Final Research Achievements

With the development of digital devices and social media, tons of image and video signals have been generated and stored all over the world. These signals are often privacy sensitive data such as videos in surveillance systems, medical records, and face images, or commercially sensitive such as digital cinema movies. To overcome such situations, this research was done to develop visually image encryption methods and signal processing in the encrypted domain. The research outcomes are mainly as follows: (1) Image identification schemes in the encrypted domain for JPEG2000 images, (2) Development of copyright- and privacy-protected image trading systems, (3) Copyright- and privacy-protected image trading systems with enhanced performance.
