Effective usage of audio watermarking with the fibonacci series in shielding the digital multimedia from malicious attacks

Abstract

In the present scenario the use of digital is increasing day by day and the necessity of protecting data from various malicious attacks is also increasing as well. Digital Multimedia can be protected with effective usage of Audio Watermarking using Fibonacci Series from malicious attacks. Watermarking is one of the methods to embedding information into a signal such as pictures, audio and video in a way that is difficult to remove. If the signal is copied, the information is also transferred along with the signal in the copy. Watermarking is rapidly increasing to shield digital multimedia as it enables copyright protection, ownership verification and malicious attacks. Audio marking is method embedding in a audio signal and it is used to identify ownership of copyright. Presently various Audio Watermarking techniques are available to protect digital multimedia. This paper mainly focuses on the usage of Audio Watermarking by changing some magnitudes of the Fast Fourier Transform Spectrum. The main motto of this technique is first divide the Fast Fourier Transform Spectrum into short frames and then changes the magnitude of the selected Fast Fourier Transform samples by using Fibonacci numbers. This technique emphasizes that Fibonacci Series based on Audio Watermarking proves to be efficient to shield Digital Multimedia from malicious attacks.
