| Popis: |
The work in this paper presents a novel data hiding technique with high density of payload data for transmission of sensitive message in a concealed form within a digital audio signal used as cover. To enhance security, the payload message is embedded into discrete Fourier transformed coefficients of time-domain audio samples, to make any potential hacking attempt harder. The proposed technique increases the density of the transmitting message by inserting multiple bits of message data at multiple LSB layers, selected pseudo-randomly within the binary counterpart of each transformed frequency coefficient. Furthermore, a 160-bit message digest is inserted along with the message data to validate the integrity of the extracted message by the receiver. Thorough experimentation has been carried out to evaluate the effectiveness of this method taking different types of cover audio and message as input to various standard performance metrics. |
