Autherizing Audio Remote Access using Encoded Hidden Data


Remote access to data or special applications became essential part of the internet applications for fast and secure data usage. Accessing data using audio has been used frequently but audio needs to be verified. In this paper, authorizing audio is done by hiding identification information within the audio. The hidden information is encoded using Huffman tree, encrypted using knapsack algorithm and hidden in specific parts of the audio. The suggested method was tested for corruption and quality of the authentic audio using subjective and some objective test metrics.
