Authentication scheme based on Biometric is proposed to enhance security for storing information on the server. One of the biometric feature most widely used is fingerprint. A novel method to protect fingerprint privacy is to generate a virtual identity. Extracting the features from the two fingerprints given by the user, virtual identity is generated. Cryptography is applied to generate key using RSA algorithm. The generated key is used for encrypting the data that has to be stored on the server. For retrieving the file/data from the server, the key is generated by applying the RSA algorithm to fingerprint and filename given by the user. If the generated key matches with the key stored on the server, then the file/data will be decrypted with the key and used by the user. A secured way of encrypting and decrypting a data can be achieved by using Biometric based authentication scheme.
