摘要：This Steganography is the skills of concealing secrete information into other object like image has been widely used in term of information security. The technique of standard steganography allows the secrete information for not being perceptible to an viewer. Moreover, there is another technique that is normally used to enhance the security of the information, which is usually called Cryptography. Cryptography is also the skill and knowledge of transforming information into a series of bits that appears as arbitrary and worthless for the viewer. Most of the time, user have used only single method either Cryptography or Steganography to protected the secrete information. The encryption/decryption process have gained high recognition in broadcast of secrete information like images and those generated for the security organizations which may enclose images of tactical planning information and geographical position images. However, the amalgamation of Steganography and Cryptography that is proposed can be useful for improving the security of secrete information. The presented concept in this paper also provides an easiness of exchanging confidential information secretly between a sender and a receiver with multimedia files like images as carriers of the information. For the purpose, proposed work has designed an efficient encryption algorithm considering the various cryptanalytic attacks which evolved as the security enhancements were formulated. Proposed technique is the implementation with high PSNR and entropy with correlation complexity
