Decryption of Encrypted Fractional Wavelet Transformed Image Using Its Inverse
Ravikumar. K, Diana Vinster Nadeen. A, Jon Arockiaraj J · 2023
There are various encryption processes to secure a signal or an image. This encryption is much more effective and feasible with the usage of wavelet transform. Here the emphasis is given to fractional wavelet transform because even the restrictions of wavelet transform can be rectified by fractional wavelet transform (FrWT), also the signals can be featured in time domain and in particular fractional frequency domain. In this article we would wish to concentrate on the decryption of the encrypted image. The encryption is performed by FrWT as the security level is much higher when compared.
