Data Encryption Algorithm using Asymmetric Key Derived from Fingerprint Biometric Features

Abstract: Security is a one of the major concerns in the present because of increasingtheinformation quantity and theft. Due to these causes, an efficient security system is more importantto protect the personal information. This leads to use password, keys, etc.to secure the information. Fingerprint Encryption is preferable biometric technique for securing text because of its parallelism, vast storage and fast computing quality. In this paper will use the features provided by the fingerprint of the information sender to extract a new encryption method depending on the distribution of the hells and valleys of the finger print since this distribution differs from one finger to another and from one person to another. The proposed method will be used for text data transmission. The types of encryption key generators which will be used through this research are the private key generators. Extracted the feature vector from fingerprint. Then the feature vector is converted to encryption key. In general, encryption algorithms use this fingerprint key to encrypt and decrypt the data. In encryption and decryption we use a new algorithm, which depend on look up table to encrypt and decrypt message. The security is enhanced in this paper by using fingerprint encryption technique.
