Abstract— Steganography is a method of secret Communication that hides the existence of secret Data. Steganography is the art of hiding the existence of the communication message before sending it to the receiver. Stego-keys can come in many forms; they can be a password or an agreed-upon place to look for the hidden message. Early research concentrated on watermarking to protect copyrighted multimedia products (such as images, audio, video, and text) [1, 8]. Amongst the many existing biometrics, fingerprints are considered to be one of the most practical ones. Steganography is used for secret or covert communication. Techniques such as watermarking and steganography have been used in attempt to improve security of biometric data. In this research we propose a new approach for solving that problem by using the algorithm based on Sequential Technique where the input process starts from the center of the cover.
