Network Security is the most vital component in information security because it is responsible for securing all information passed through networked computers. [1] In this paper we discuss and survey IDEA, AES, and Blowfish for Image Encryption and Decryption. In today’s world it is a crucial concern that while transfer image from one network to another network over the internet, the proper encryption and decryption should be applied so that unauthorized access can be prevented. For this, we will survey related researchers and done some problem identification and suggest some future suggestion which can be useful for image encryption.
