Description
Summary:This paper suggests a new proposed algorithm for encryption/ decryption audio files based on discrete wavelet transform (DWT) and biometric features to provide a high level of confidentiality and reliability. The proposed algorithm used number of hand geometry measurements properties as keys to encode and decode the audio file, combine with using the discrete wavelet transform (DWT) in order to increase the efficiency of the encryption process. Subjective and objective measures are applied to the resulted signal. They cleared that the retrieved audio signal has very acceptable loosing of its data with certain keeping the main decrypted message in a good understanding on the receiver side. This achieves the major target of encryption processing.
