Cryptography is the backbone of modern security systems. The conventional problem of such systems is that they cannot authenticate genuine users. So, a new scheme based on RFID is introduced such that it has benefits of both systems i.e. security and genuine user authentication. Here, AES algorithm is used for encryption and decryption. The secret key is extracted from iris feature and is used to encrypt and decrypt audio signals. Audio signals are processed in real time. Security of audio signals is achieved through the use of encryption; this information can be securely transmitted and stored for the access of only the proper Individual.
