Embedding Watermark in Palmprint Images


With the wide spread utilization of biometric identification systems, establishing the authenticity of biometric data itself has emerged as an important research issue. This paper proposes a new spatial method in order to embed watermark data into Palmprint images, without corrupting their features. This method inserts watermark data after determining the features regions to avoid the regions used for Palmprint recognition. Watermark data are embedding according to certain conditions. In this way, the authenticity of the Palmprint image can be established. In process of extracting watermark does not require the original Palmprint image.
