Fine-Grained Access Control on Image Encryption and Retrieval Techniques Using in Image Protection and Management

Network is a convenient but insecure environment, which might suffer from the potential security risks, such as personal privacy leakage and illegal broadcasting. Image encryption is a way to protect personal privacy to encrypt an image into a noise-like pattern and no one can decrypt the encrypted data without the secret key. In the past, researches focused on encrypting a whole image, but not supporting a fine-grained mechanism. Fine-grained image encryption is essential in some applications, such as photos in social networks, to authorize partial contents to authorized users. Moreover, the encrypted images is difficult to management because the encrypted images are as noise-like patterns. This proposal is intended to propose a light-weight image encryption mechanism for privacy protection in mobile cloud computing. For image management, we embed a pattern on the encrypted image for users to later recognize the resources. In this proposal, we intend to propose a three-year plans to design mechanisms not only for help in health education but also for encrypted image management. 1st year: Light-weight reversible hiding in encrypted image with fine-grained encryption ability. 2nd year: Fine-grained access control on image encryption for health education. 3rd year: Image retrieval of encrypted image in cloud service for flexible image management
