A Random Selective Block Encryption Technique for Secure Image Cryptography Using Blowfish Algorithm

In the modern world, the requirement for information security has become a necessity with the progress in the exchange of data and communications through the electronic system. Due to multimedia growth the image security while transmission is major issue various complex cryptography technique are used for image security. The technique is proposed for image encryption and decryption with random selective selection and Blowfish algorithm the technique select refine part and encrypt decrypt block. the encryption and decryption time of proposed technique is better and Encryption and decryption results calculated by proposed technique is better as compared standard methods
