• This paper proposes an efficient image encryption method based on a hybrid of watermarking and cryptographic techniques. It is based on two-level security for the secure and error-free transmission of images between the IoT enabled devices. A discrete wavelet transform (DWT) based watermarking scheme is used at the first level, while at another level, an efficient image encryption technique based on a hybrid of logistic chaotic map and crossover is applied. In the DWT scheme, an encrypted secret image is used as a watermark image, where the secret image is encrypted via the lightweight cryptographic scheme. Here the hybrid of logistic chaotic map and crossover is used to produce random session keys for encryption of digital images. The use of DWT and 1-D logistic map along with crossover operation enhances the encryption effect compared to ordinary, chaotic encryption algorithms. The significance of this scheme is to improve security by using the hybrid concept. The strength of the proposed image encryption method is estimated by checking the proposed technique on various types of cryptographic attacks such as differential attack (NPCR), statistical attack (information entropy, histogram analysis, and correlation coefficient), noise attack, and prone to the secret user key. The higher value of NPCR (99.63) and information entropy (7.9973) are achieved, reflecting the effectiveness of this work.
