Abstract
The fragile watermarking technique presented in this paper is based on the pixel information. The authentication data is calculated from the pixels by using Local Binary Pattern concept. Spatial information of pixels is used for watermark calculation and it is having spatial relationship of pixels. The authentication information is calculated for the block of 3×3 using LBP operator and we have used 2 LSB for adding watermark. Local Binary Pattern is widely used for texture classification, pattern recognition and face detection. The recovery information is obtained from the pixels itself. The performance of tamper detection in proposed technique is comparatively good to earlier techniques. Image quality of recovered image is good.Keywords
