Abstract: Security Techniques are required due to the illegal access of data without permission. It is necessary to provide secured and robust technology to protect data. We have used various security techniques. Digital watermarking has been proposed for the protection of digital Medias. In this paper we are presenting and investigating the watermarking algorithms for binary images. The algorithms involve a blurring preprocessing and a biased binarization. The algorithm embeds a watermark by directly biasing the binarization threshold of the blurred image. It is controlled by a loop. Experimental results show the imperceptibility and robustness aspects of algorithms. In this paper algorithm is based on binarization method (in spatial domain) only BER performance has estimated for this technique, however there are two other major parameters those are helpful for defining the efficiency of watermarking method. In this project we are doing the proposed method analysis using the three parameters named BER (Bit Error Ratio), PSNR (Peak Signal to Noise Ratio) and MSE (Mean Square Error).
