A Novel Steganographic Approach for Securing Biometric Templates

Shweta Setiya, Chander Kant


Biometric systems are used for recognising a user on the basis of his biometric traits. During authentication some of the frequently asked questions are “Is he who he claims to be?”, “Is he a valid user for gaining access to the system?”. Biometric system answers all these questions by authenticating the users. Every second information is shared and transferred between people and it is important to make sure that what is sent by sender is what received by the receiver thus raising the demand of security. Steganography is one of the techniques used for securing the data. The secret message is hidden inside a cover media like audio, video or image with the help of a secret key. Biometric templates can also be secured with this technique. Instead of storing original templates in the database stego-image is stored. LSB is one of the common techniques that replace the LSB of every pixel of the cover image with the secret message to form stego-image.
