Proposed method for partial audio cryptography using haar wavelet transform

Abstract EN

The rapid developments in communication networks and the Internet have led to propose an encryption algorithm based on a new transfer audio data across networks more quickly.

A reduction of data audio files transferred across the network without loss of data led to merging algorithms to compress data at third-level with encryption algorithm, which maintains the confidentiality of information transmitted across the network.

This merging is aimed at the transfer of data encryption honestly with rapid retrieving.

The results are obtained by the adoption of the proposed encryption algorithm to generate a random key for possible restoration of the original data files, audio files recorded after the receipt of data without any loss of information.
