Logistic-Map Based Fragile Watermarking Scheme With Dual-Security For Image Integrity Verification In Cloud Computing Environment

Abstract

With the widespread embrace of cloud computing technology, the utilization of cloud storage has become highly prevalent, given the limited storage capacity of user’s local devices. Nevertheless, throughout the processes of transmitting, storing, and downloading digital images to or from the cloud, there is the potential for integrity violations or tampering with the images. Addressing this concern, the paper introduces a fragile dual-security watermarking scheme based on blocks and logistic maps. The purpose of this scheme is to protect digital images authenticity and integrity while they are being stored and transmitted between the user and the cloud. Before watermarking, the image undergoes a jumbling process using a logistic map, providing dual level of security. The proposed scheme employs a combination of arithmetic mean, standard deviation, and logistic map for watermark generation, as well as integrity checking or tamper detection. This results in a notable reduction in execution time, as demonstrated through experimentation when compared to existing schemes. Furthermore, the suggested method efficiently locates and identifies tampering in the event of multiple attack types, such as copy-paste, copy-move, and crop attacks. Moreover, the proposed scheme exhibits excellent imperceptibility, with average PSNR and SSIM values of 51.14178 and 0.9967, respectively, in comparison to existing schemes.
