Abstract: Secured data storage and transmission has become an important issue in the digital world due to the increased use of Internet for communication purposes. Information security is becoming more important as the amount of sensitive data being exchanged on the Internet increases. The services like confidentiality and data integrity are required to protect data against unauthorized usage and modification. Visual systems help humans to understand the scenario and improve the understanding capacity. Secure sharing of images helps not only to prevent leakage of data, but also makes it difficult to retrieve the original image in case of the image falling into the wrong hands. In this paper, the cipher feedback mode with hash function has been utilized to encrypt digital images. The proposed method is experimented, tested against security attacks and the obtained results are compared with the existing methods.

Keywords: Image Encryption, Random Number, Modes of operation, Hash Function
