Abstract

Steganography is the art and science of writing hidden messages or hidden messages in such a way that besides the sender and the recipient, no one knows or realizes that there is a secret message. Algorithms Spread Spectrum Spread Spectrum Steganography is scattered as encrypted message (encrypted) through images (unlike in the LSB ) . To read a message, the receiver requires that crypto-key algorithm and stego-key. In a file security system sometimes requires a password protection that normally uses certain. But sometimes the password can be extracted through a specific application, because the file also has an ini file that uses passwords. In this regard, the author wants to do a research in file protection by hiding the file into a bitmap image using the algorithm spreads spectrum. setelah testing, it was found that the result of the time required in the process of un-steganography steganography and have differences, the size of the file bitmap image has a difference before and after the process of steganography is done, testing the decryption process uses the data that has been encrypted document to be returned kedata variations as original. whatever user enters wrong key, the document data will be scrambled back
