Abstract

Communications and information technology is rapidly grows and provides a major influence on people's lives. The rapid development of information technology is currently supported by the importance of the need for information. It can be seen from the development of today's internet network is rapidly increasing. Informations that transmitted is not meant for everyone.

Cepatnya perkembangan teknologi informasi saat ini didukung dengan pentingnya kebutuhan akan mendapatkan informasi. Hal ini dapat dilihat dari berkembangnya jaringan internet saat ini yang semakin pesat. Informasi yang dikirimkan tidak hanya informasi untuk semua orang. Seiring dengan perkembangan teknologi tersebut, ancaman terhadap keamanan informasi yang dibutuhkan semakin besar, terutama untuk informasi yang dirahasiakan tersebut. Berbagai ancaman di dunia maya seperti hacker, cracker, carder membuat orang khawatir akan keamanan informasi yang dikirimnya. Kekhawatiran inilah yang membuat berkembangnya teknik penyembunyian informasi yang akan dikirimkan. Teknik penyembunyian informasi yang cukup terkenal adalah steganografi.
