With the high availability of internet and the huge growth of technology information security has become complex and a problem that needs urgent attendance, in this present era, security has become one of the major concerns in the IT industry, to enhance the security of information certain encryption mechanism has been created to resolve the issues. Encryption is the process of converting a message or information into code known as cipher to prevent an unauthorized person from acquiring access to the information. Another technique use in this project is Steganography which is the hiding of the existence of information so that the information can be transmitted undetected. Steganography allows the sender hide the message within a cover message [1]. The use of steganography, in this project is combined with encryption to create an extra layer of security information. This project Fibonacci series technique is use for encryption and decryption to secure the information, this technique can secure any type of file and the encryption and decryption is based on loss-less and key dependent. And the application of Audio and Image Steganography which will be used to hide the encrypted information, hence providing extra layer of security for files. These mechanisms are implemented using python.
