In modern civilization information, security is a crucial problem. Image encryption and watermarking can effectively protect information from unauthorized access. This paper introduces a new vigorous symmetric optical image encryption and watermarking technique. This technique depends on a novel dynamic delay chaotic hopping pattern (DDCHP) combined with double random phase encoding (DRPE). To get...
Converting information (data) from its original form to another form is known as encryption as in order to access rising the information protection. The encryption created on chaos theory includes some dynamic methods to improve the protection of image encryption. In this work, encryption image is achieved by using a different chaotic mapping. The original image is split into blocks and then different...
