A Secure Optical Encryption Using DWT and Bit Swapping

Because of its beneficial qualities, including quick processing and penalization, optical security solutions have acquired a lot of success. Numerous optical encryption solutions based on various encoding algorithms are offered by optics. In recent years, optical encryption has gained popularity as a study area. The creation of safe picture encryption methods has been made easier and more effective by the chaos-based cryptographic algorithms. In this research, a new encryption scheme created on Discrete Wavelet Transform (DWT) and bit swapping. The cover image is initially distributed into its bit plane. Extracting Least Significant Bit (LSB) from the bit plane, convert 3x3 blocks and given DWT with swapping bits for encryption. According to the experimental findings, the suggested algorithm achieves better performance and is highly secured.
