Cryptography in Image Using Blowfish Algorithm

S. S. Sudha, S. Divya

Abstract: Cryptography is the art of secrete writing, cryptography is the science of encrypting the image. The study of encrypting is converting the original information from its normal form to incomprehensible format. These days securing the datas has become difficult, to reduce the complexity, cryptography has been used. Image data security is the indispensable portion in communication, defence and networks and so many. Providing security is more important for the image. In this paper securing the image is executed with a Blowfish algorithm from the perspective of cryptology. Blowfish is used for the applications, where the key doesnt change often and has a larger space to store the data. Encryption and decryption is performed to obtain the original hiding information from the image.
