It can be primarily based on three most important components: the Jigsaw transform, Langton’s ant, and a novel solution to add deterministic noise. The Jigsaw transform was utilised to hide visual facts proficiently, whereas Langton’s ant along with the deterministic noise algorithm give a reputable and secure method. As a case study, the proposal was applied to highresolution retinal fundus pictures, where a zero mean square error was obtained in between the original and decrypted image. The strategy efficiency has been verified by means of several testing strategies, like statistical evaluation (histograms and correlation distributions), entropy computation, keyspace assessment, robustness to differential attack, and crucial sensitivity evaluation, showing in each and every a single a higher safety level. Furthermore, the system was compared against other functions showing a competitive functionality and highlighting using a big keyspace (1 101,134,190.38 ). Apart from, the method has demonstrated sufficient handling of highresolution images, acquiring entropy values between 7.999988 and 7.999989, an typical Quantity of Pixel Adjust Price (NPCR) of 99.5796 0.000674, plus a mean Uniform Typical Transform Intensity (UACI) of 33.4469 0.00229. In addition, when there is a little modify inside the essential, the method does not give added data to decrypt the image.
