: In modern time security plays an important role in every field. The various types of media carry information like image, audio and video and protecting these from unauthorized access is an important area of active research. To provide strong security we use bio-cryptographic technique. In this paper we taken a review of cryptography key, Steganography key and fusion based key construction using finger vein pattern. Finger vein pattern are difficult to copy because blood flow needed during image capturing. Cryptography plays a very important role in data security. Steganography is the best technique for hiding the data. It is the science or art of embedding private information into the cover media with the alteration to the cover image, which cannot be easily recognized by human eyes. The key of many different sizes can be generated using these methods with minimal amount of time complexity and space complexity.
