Embodiments of the invention provide a JPEG2000 image-oriented combined fingerprint embedding and encryption method and apparatus, which is applied to a social multimedia sharing network. According to the method, for the problems of illegal copying, pirating, plagiarizing, resource limitation and the like in an existing multimedia content sharing process, a digital image is taken as a research object and is subjected to fingerprint embedding and chaotic encryption based on tree structured wavelet transform and a hierarchical community structure, so that the security and confidentiality of multimedia data such as the image and the like in a propagation process can be effectively improved; the method has traceability and expandability; and in addition, the method is simple and can be applied to an environment limited in storage and bandwidth resources.
Description
Technical field [0001] The present invention relates to the technical field of information security, in particular to a method and device for joint fingerprint embedding and encryption for JPEG2000 images. Background technique [0002] With the development of mobile multimedia social networks, the storage, copying and dissemination of social multimedia for mobile devices has become very popular, which not only evolves into a big data problem, but also causes illegal abuse of multimedia content, leading to property rights disputes and privacy leaks. In addition, due to the limited capacity of fingerprint codes, the dynamics of social networks, the characteristics of multimedia big data, the bandwidth of mobile networks, and the limited resources of mobile devices, the existing multimedia security technologies cannot be applied to resource constraints. Environmental issues arise. Therefore, how to effectively solve the above problems has become a research hotspot for those skilled ...
