“…Chaotic maps are extremely sensitive to initial conditions, and are nonlinear, highly random and unpredictable in nature. These characteristics are used in cryptography applications in order to provide better security in the channel [ 3 , 4 ]. The main motivation of the proposed research work was to prevent multimedia threats in the communication channel.…”

“…For example, a damaged medical image may affect a doctor's diagnosis and endanger the patient's life. Therefore, there are many images encryption algorithms [23,25,26] and image steganography [27,28] are proposed to ensure the security of images. In addition, to prevent the integrity of the image from being tampered with after encryption, the image recovery scheme has become a research hotspot.…”

“…Among varieties of techniques to protect privacy, e.g., anonymization [10], encryption [11], data access control [12], data outsourcing [13], digital forgetting [14], and data summarization [15], differential privacy (DP) offers a promising approach to make the contribution of individual data items hardly distinguishable toward given data analyzing tasks [16]. Such a feature leads to a provable privacy guarantee with a quantitative privacy measurement called privacy budget [17], making DP the de-facto standard for privacy preservation in data analysis both in academia and industry [18,19].…”
