Abstract

Audio file steganography can be used as an effective and efficient method to hide messages. LSB based approach is the simplest steganographic technique among the various types for hiding secret information in audio formats. The approach is decided independent of the relationship between audio samples and the size of the secret messages. Efficiency of the output message is reduced when low data rate is used for hiding the message in lower power audio samples. The performance of data hiding in high power of audio is discussed in this paper. To identify the higher frequency, range from a given sample carrier and to hide the messages in the identified range, the LSBMR algorithm is used. The carrier wave is pre-processed in order to reduce the possibilities of intrusion detection. Experimentation of the adaptive steganography is performed on the files that are in. wav format. PSNR and MSE parameters are used for performance analysis. The threshold value of the audio carrier is depending upon the length of the message is used. The content of the secret information and threshold value of the carrier audio decides the number of samples for evaluation.
