Perkembangan teknologi informasi dan komunikasi menjadi kian pesat. Namun keamanan suatu pesan kurang diperhatikan, maka dari itu tersebut rentan akan pencurian. Salah satu teknik untuk mengamankan yaitu steganography, steganography merupakan menyembunyikan di dalam media penyisipan (citra). pengaplikasianya file cover harus lebih besar dibanding object. Oleh karena diperlukan interpolasi menin...

A new and efficient steganographic method for embedding secret messages into a gray-valued cover image is proposed. In the process of embedding a secret message, a cover image is partitioned into non-overlapping blocks of two consecutive pixels. A difference value is calculated from the values of the two pixels in each block. All possible difference values are classified into a number of ranges...

Data Hiding is one of the challenging issues in the field of Network Security. Unlike cryptography, Steganography is used to hide the existence of secret message by embedding the message behind any cover object like image, text, audio, video files. Various authors proposed, various methods for hiding secret information behind gray scale images such as least significant method, gray level modifi...

Over the <span lang="EN-US">past few years, in order to improve hiding capacity and peak signal-to-noise ratio (PSNR) value, several steganographic techniques have been developed. Steganography has become a popular technique transmit secret data through any medium. In image steganography, human eye cannot easily identify hidden which is embedded into image. Small changes are also not dete...
