In this paper, we propose data hiding and extraction algorithms for binary images. Handwritten Signature Image can be transmitted from source to target securely over network after processing the source image by using this proposed Data Hiding Algorithm. According to the algorithm, size of the carrier image must be double (or more) the size of source image. If necessary then additional bytes or noise...
In this paper we propose a new Handwritten Signature Recognition Algorithm. The Algorithm is based on pixel-to-pixel relationship between Images. The Algorithms are based on extensive statistical analysis, Standard Deviation, variance and Theory of Cross-Correlation. This is an extension work of Handwritten Signature Identification. This Algorithm supports the application environment and we strongly...
In this paper, we propose a technique for embedding watermark bi-color image into color image. At the source, the handwritten signature image (bi-color image) is encoded at the end of the color image. Double folded security of handwritten signature can be achieved (over the untrusted network) by; first, the starting point of encoding the image data is depended on the size of the images; second, the...
In this paper we propose a new handwritten signature authentication scheme. The scheme consists of two main rule set algorithms and one authentication algorithm. The Algorithms are based on extensive statistical analysis, Mean variance and theory of estimation. This is an extension work of handwritten signature identification. This scheme supports the application environment and we strongly believe...
