iPrivacy: LWE Enhanced image protection over cloud storage


Outsourcing image data to the cloud is the major challenge of cloud security that must be addressed, especially for maintaining privacy. Image consumes more space while compared to text. Hence the traditional techniques like AES, DES, RSA are well fitted to text data rather than image. The leakage of sensitive image is increased while outsourcing. In this paper, we design the framework for a novel light weight encryption(LWE) to outsource the encrypted image to the cloud without leaking the sensitive information on the cloud server and maintains the privacy. It also maintains the balance between security and computational overhead in client system to enhance privacy. Images cannot retrieve even by the untrusted cloud vendors. Extensive experiments are conducted to prove that the proposed work consumes execution time with standard AES to provide superior performance of client system. The proposed algorithm consumes energy more than 50% with standard AES. The proposed LWE work has demonstrated the encryption/decryption of collecting various images in the experimental results and performance analysis to satisfactory security.
