Today, the world is going to be digitized anyway. Each business unit, each government and private sector, each research unit uses the digital image as a transfer mode for all critical data. These images on the internet will not be secure. Therefore, there is a need for image security. Due to the rapid growth of digital communication and multimedia application, security becomes important issue of communication and storage of images. Encryption is one of the ways to ensure high security. The images are used in many fields, such as medical, military science. Modern cryptography provides techniques to protect information and protect multimedia data. In recent years, encryption technology has it developed rapidly and many image encryption methods were used to protect the confidential image data Unauthorized access. In this paper, different image encryption techniques have been discussed from which researchers can get an idea for efficient techniques to be used and also discusses the basic image security techniques or image encryption technique. The survey of the recent research in the field of image securities like Genetic Algorithm Based Approach, RSA Algorithm Based Approach, Arnold Transformation Based Approach, DCT, DFT, SVD, cryptography based approach.
