Comparation between Spatial Domain Steganography Techniques and Audio Transformation Domain
Description:
The internet provides convenience in conveying information or exchanging data. Data sent via the internet network can have very confidential properties. To maintain the confidentiality of the data sent, a technique is needed, one of which is the Steganography technique. Steganography techniques have several methods, the most commonly used method is the Least Significant Bit (LSB) method, that is, by inserting the least significant bits in the storage media. Another method used in Steganography is the Spread Spectrum (SS) method. In this method, pseudorandom is used to randomize secret messages before being added or inserted into the cover carrier. In this paper the two methods above are applied to digital audio. Then the results are analyzed to compare the weaknesses and advantages of each method by comparing the audio quality before and after insertion, as well as the quality of the secret message that has been extracted. From the tests performed, it was found that the audio steganography quality generated by Spread Spectrum method is better than the Least Significant Bit (LSB) method as shown by the SNR value generated by the Spread Spectrum method is greater or better than the LSB method where the difference in SNR values generated by both the method has a small difference in value, the difference value reaches 8 db, but the message quality obtained in the extraction of both methods is just as good.
