چکیده
sofa628 busstation1111 backdoor1816 Server results Background. Recently, storage and processing large-scale visual media data are being outsourced to Cloud Data Centres (CDCs). However, the CDCs are always third party entities. Thus the privacy of the users' visual media data may be leaked to the public or unauthorized parties.In this paper we propose a method of privacy preserving foreground extraction of video surveillance through chaotic mapping based encryption in the cloud.

DoS-Resistant Attribute-Based Encryption in Mobile Cloud Computing with Revocation
Security and privacy are very important challenges for outsourced private data over cloud storages. By taking Attribute-Based Encryption (ABE) for Access Control (AC) purpose we use fine-grained AC over cloud storage. In this paper, we extend previous Ciphertext Policy ABE (CP-ABE) schemes especially for mobile and resource-constrained devices in a cloud computing environment in two aspects, a ...
متن کاملImage encryption based on chaotic tent map in time and frequency domains
The present paper is aimed at introducing a new algorithm for image encryption using chaotic tent maps and the desired key image. This algorithm consists of two parts, the first of which works in the frequency domain and the second, in the time domain. In the frequency domain, a desired key image is used, and a random number is generated, using the chaotic tent map, in order to change the phase...
متن کاملA stack-based chaotic algorithm for encryption of colored images
In this paper, a new method is presented for encryption of colored images. This method is based on using stack data structure and chaos which make the image encryption algorithm more efficient and robust. In the proposed algorithm, a series of data whose range is between 0 and 3 is generated using chaotic logistic system. Then, the original image is divided into four subimages, and these four i...
متن کامل3D Point Cloud Encryption Through Chaotic Mapping
Three dimensional (3D) contents such as 3D point clouds, 3D meshes and 3D surface models are increasingly growing and being widely spread into the industry and our daily life. However, less people consider the problem of the privacy preserving of 3D contents. As an attempt towards 3D security, in this papers, we propose methods of encrypting the 3D point clouds through chaotic mapping. 2 scheme...
متن کاملA New Method for Encryption of Color Images based on Combination of Chaotic Systems
This paper presents a new method for encryption of color images based on a combination of chaotic systems, which makes the image encryption more efficient and robust. The proposed algorithm generated three series of data, ranged between 0 and 255, using a chaotic Chen system. Another Chen system was then started with different initial values, which were converted to three series of numbers from...
