An enhanced RGB scan image encryption using key-based partitioning technique in cloud

Abstract

Cloud is a group of remote systems available on the web to manage and store information. As a “utility” cloud provides better use of resources and minimizes initial cost. Nowaday’s, importance for secured storage of Health records and Medical images has drastically improved in cloud environment. Public clouds are ubiquitous by nature, it is the user self-responsibility to achieve privacy for their own data. Existing techniques achieve confidentiality using standard encryption algorithms. This paper proposes a hybrid scheme for encryption of plain/medical images using key dynamics before publishing them. Other users can decrypt the cipher image only after they are authenticated by the owner with restricted access. Based on experimental results, a hybrid encryption scheme demonstrates excellent level of confidentiality.
