The internet and the World Wide Web have revolutionized the way in which digital data is distributed. The growing possibilities of modern communication need special means of security especially on computer network. In this paper a new randomized secure data hiding algorithm using file hybridization is proposed for strengthening the security of information through a combination of cryptography and steganography with random transformation and file hybridization. Steganography is the technique of hiding confidential information within any media. Steganography is often confused with cryptography because the two are similar in the way that they both are used to protect confidential information. The difference between the two is in the appearance in the processed output; the output of steganography operation is not apparently visible but in cryptography the output is scrambled so that it can draw attention. Steganlysis is process to detect of presence of steganography. Steganography hides the message so it cannot be seen. A message is a cipher text for instance, might arouse suspicious on the part of the recipient while an "invisible" message created with steganography. This approach includes a high degree of security and data protection implemented by the concept "Message Sending" and "Secrete Communication" at large scale. This System includes three main parts Administrator, Encryption and Decryption. The Administrator creates the monitor accounts. Encryption uses the service of the system & authenticates the user. Decryption is used to decrypt data.
