A Novel Scheme of Data Hiding in Binary Images

This paper proposes a new method to embed data in compressed binary images (JPEG), including scanned text, figures, and signatures. The method manipulates "flippable" pixels to embed data without distorting image. Shuffling is applied before embedding to provide more security. The hidden data can be extracted without using the original image. The proposed method uses look up table which is to be used for extraction of data at other end is made more compact, secure. After applying proposed method the image will be distorted no drought but human eye will not recognize the change in the image. The proposed data embedding method can be used to detect unauthorized use of a digitized signature, and annotate or authenticate binary documents.
