Secure and oblivious information hiding in binary image

This paper proposes effective digital watermarking scheme to hide information in binary image. The original image is not needed when retrieving the digital watermark and a key is used to protect the hidden information. In order to produce little annoying noise as possible to the binary image, this scheme uses the features of Human Visual System in binary image. Finally we give details on how to implement this algorithm efficiently. © 2013 IEEE.
