Optimized Watermarking Using Artificial Bee Colony Algorithm and 6-D Hyperchaotic Map Based Image Cryptographic Scheme

This work presents a hybrid image encryption approach that combines an optimized watermarking system with a 6-D hyperchaotic map. The optimized watermarking technique combines the Hessenberg decomposition (HD), discrete wave transformation (DWT), and singular value decomposition (SVD) with the artificial bee colony algorithm (ABC). In this, multi-level DWT is used to first split the host image into many sub-bands, and the resulting coefficients are then supplied into HD during the embedding stage. On SVD, simultaneous watermark operations are carried out. Ultimately, the watermark is integrated into the used host image by the optimal scale factor. The optimal scaling factor for the optimized watermarking system is determined using the artificial bee colony algorithm. A 6D hyperchaotic map is then used to encrypt the watermarked image that results. During the encryption procedure, a number of random chaos sequences are used to first jumble and disperse the original image sequences. The several encoded sequences are eventually combined to generate an encrypted image. The experiment’s findings demonstrate that the hybrid strategy that has been recommended is more resistant to frequent attacks than certain alternative approaches.
