STEGANOGRAFI

APPLICATION PROGRAM SPECTRUM SPREAD STEGANOGRAPHY

The exchange of traffic information in cyberspace grows fast. In all areas of life utilize technology to

exchange information. One of the media owned by many people is mobile device such as mobile phone and tablet

computer. In fact many people have been using mobile devices for information exchange function, and expect

important when the information is confidential. One way to secure information sent is the concealment of

information into a media so that information hidden is beyond recognition by the human senses, which is

commonly referred to steganography. This research studied and implemented steganography using spread

spectrum Method on Android-based mobile devices. The results showed that the inserted image before and after

the message was inserted is not different with PSNR value of about 75.
