CHAPTER 2 LITERATURE SURVEY Biometrics are automated methods of recognizing a person based on a physiological or behavioural characteristic. Using a unique, physical attribute of your body, such as your fingerprint, it should be to effortlessly identify and verify the genuine person in the market today. There are techniques that makes use of either a single biometric or multi modal biometric .There are many advantages in using the single biometric system such as accurate identification, ease of use ,highly secured. However most of the techniques used in single biometric system are easily hacked and traced in the recent years. Also these single biometric have equal disadvantages such as noisy data. There are many advantages of multibiometric system over single biometric system , because more than one biometric feature is taken and fused together to enhance the security. Many systems were proposed by taking…show more content…
Different X-OR models namely X model X-OR, sine model X-OR , X-OR is used.Normally the XOR returns true if both the inputs are different else the XOR will return output as false.The X-Model X-OR is used in Parallel addition algorithm,Sine model X-OR is used in Listranking algorithm and finally Butterfly X-OR is used in Butterfly algorithm for the purpose of encryption. The inputs for the parallel addition algorithm are taken by using leftfingerprint acts as a plain text,right fingerprint acts as a key1 and palm acts as a key2.The parallel addition algorithm uses X-Model X-OR model which makes the inputs to do XOR operation in the format of X type with the inputs of 2N.The X-Model will end when X type cross the value of N=8.The output from the X-OR model will taken and fed to the parallel addition
