Binary Textual/documents Image Authentication by Embedding Security Code Using Wavelet Transform Encoding

In the existing scenario, the digital images are scanned for their originality or tamper proofing by using the water marking algorithms. However, the water marking algorithms are normally suitable for high color resolution images and do not suit to the textual images i.e. binary images or black and white images. It is very tedious task to embed secret codes or authenticated code in the text images. Further, the task becomes more difficult for the smaller images. Therefore, ensuring the legality of the digital text documents becomes a big challenge in the existing digital communication world. Further, the text image i.e. document material should not be altered to the first recipient in the communication path so that the general/visible textual matter is reached to the person directly receiving the text image. However, the embedded or hidden data has to be retrieved from the text image for authenticating it’s genuinely. In the proposed work, the digital text images are targeted for ensuring the authenticity using the high data embedding algorithm.
