High Security Multiple-image Encryption using Discrete Cosine Transform and Discrete Multiple-Parameter Fractional Fourier Transform
—A multiple-image encryption scheme is proposed by using discrete cosine transform and discrete multiple-parameter fractional Fourier transform (DMPFRFT). Each image is performed by discrete cosine transform and filtering procedure and then multiplexed into a complex signal. After operated by a pixel scrambling, the complex signal is multiplied by random phase mask, and then encrypted into one...
متن کاملThe discrete fractional Fourier transform
We propose and consolidate a definition of the discrete fractional Fourier transform that generalizes the discrete Fourier transform (DFT) in the same sense that the continuous fractional Fourier transform generalizes the continuous ordinary Fourier transform. This definition is based on a particular set of eigenvectors of the DFT matrix, which constitutes the discrete counterpart of the set of...
متن کاملSampling Theorem Associated with Multiple-parameter Fractional Fourier Transform
We propose a new method for analysis of the sampling and reconstruction conditions of signals by use of the multiple-parameter fractional Fourier transform (MPFRFT). It is shown that the MPFRFT may provide a novel understanding of sampling process. The proposed sampling theorem generalizes classical Shannon sampling theorem and Fourier series expansion, and provides a fullreconstruction procedu...
متن کاملA Novel Image Encryption Scheme based on Multiple Parameter Discrete Fractional Fourier Transform
Security is one of the most challenging aspects in internet and Multimedia applications. Encryption is a process which is used to secure data. The Encryption algorithms and suitable transforms play a crucial role to form efficient security systems. In this regard the original information in the existing security system based on the fractional Fourier transform (FRFT) is protected by only a cert...
متن کاملTwo dimensional discrete fractional Fourier transform
Fractional Fourier transform (FRFT) performs a rotation of signals in the time—frequency plane, and it has many theories and applications in time-varying signal analysis. Because of the importance of fractional Fourier transform, the implementation of discrete fractional Fourier transform will be an important issue. Recently, a discrete fractional Fourier transform (DFRFT) with discrete Hermite...
