| description | The authentications of digital images have become the center of attentions for certain group of companies since the number of doctored images increased. Tampering the digital images in a way that it’s impossible to be detected by naked eyes has become easier with development of image editing tools. Digital watermarking can preserve the authentication of digital images. In this paper we proposed an efficient image tamper detection method using 3 LSB (last significant bit) watermarking technique which is able to authenticate the digital image and detect the tamper locations accurately. In the proposed algorithm a 12-bit watermark key will be created from each block of host image which will be embed to last three significant bit of each block. Our proposed method improved tamper detection technique proposed by Prasad’s in sense of tamper detection rate by 40 percent. The experimental result clearly proved the efficiency of our proposed method. |
