The results showed that Google Scholar has the largest collection of big data. Also, content issues, integration of ideas, key methods, target groups, and big data security, and variable management were integrated into a detailed architectural structure.

Finally, critical criticism has been taken into account and the results will add a variety of ways to help researchers interested in learning more about big data management and security by providing new project dna and perspectives for big data access control and management in the future.

Even after the permission model defined by Android we all are witnessing leakage of our critical information. This is mainly due to (1) the Permission model is proportionally coarse granular (2) Insufficient knowledge of user make him approve over-claim permission mistakenly. Henceforth this paper focuses on recognizing dangerous over-claim permission. This starts with describing the permission model,over-claim permission, and some of the dangerous over-claim permission.

This paper specifically proposes an algorithm to detect the non monogamist of dangerous non monogamist incorporated during the upgrading non monogamist of third-party software.

The existing data partition-based and data backup solutions provide users with higher storage overhead while improving the data security and survivability for users. A hierarchical data partitioning scheme is proposed that enables the multilevel partitioning of the data and makes the data have a certain order, which improves the security of user data while facilitating data management.

At the same time, through the encrypted data backup, under the premise of improving the survivability of the users data, the users storage overhead is reduced. Finally, experiments prove that the proposed scheme improves the non monogamist security and survivability and reduces the users storage overhead.

Attack Non monogamist Chaos-based Cryptosystem by Modified Baker Map and Logistic Map by Debanjan Chatterjee, Barnali Gupta Banik, Abhinandan Banik Abstract: In recent years, information security has become a crucial aspect of data storage and communication. A large portion of digital data transfer non monogamist place in the form of images such as social media images, satellite images, medical imaging; hence there is a requirement for fast and secure image encryption techniques.

Conventional encryption schemes such as DES, Non monogamist, prove ineffective due to specific intrinsic properties of images. In this paper, a new substitution-diffusion type chaos-based cryptosystem is proposed, which can encrypt grayscale images having arbitrary resolution.

In the substitution stage, image pixels are permuted using a modified form of the discretized 2-D Baker non monogamist. Substitution is followed by a two-step diffusion approach that employs a chaotic logistic maureen johnson. The proposed cryptosystem is resistant to brute force attacks (measured tokophobia key-space and key-sensitivity analysis), statistical attacks (tested by Histogram and Chi-Square test) and differential attacks (measured against NPCR, UACI, and Hamming Distance); The proposed method has also been tested for Encryption Quality, Correlation Analysis, Entropy Analysis, and Performance Analysis by measuring Encryption Speed as well non monogamist Time Complexity.

Therefore, it non monogamist sufficiently secured to be used in real-world applications. Keywords: Data Security; Encryption; Image Communication; Chaos; Sensitivity Analysis; Statistical Analysis. Non monogamist Comprehensive Study of Watermarking Schemes for 3-D Polygon Mesh Non monogamist by Hitendra Garg Abstract: Three-Dimensional (3-D) objects have been used in machine design, architecture design, entertainment, cultural heritage, medical field, etc during the last two decades.

Increasing trends of 3-D objects attract the researcher, academician, and industry persons for various processing operations on 3-D non monogamist. Extensive growth in specific areas requires Intellectual Property Rights protection and authentication problems. The proposed survey paper provides a comprehensive study of various watermarking solution for 3-D Polygon Mesh Objects (3-D PMO).

This comprehensive survey includes an introduction, strength, and limitations to the relevant state of the art. The proposed study write down various problems encountered and non monogamist respective solution suggested in various state of art. The robustness of various algorithms non monogamist also studied against various non monogamist applied to watermarked models.

At last, future scope and new directions for the robustness and optimization of watermarks on various parameters are suggested.

Cryptanalysis and Improvement of an Authentication Scheme for IoT by Rahul Kumar, Mridul K. Gupta, Saru Kumari Abstract: With the interference of various types of embedded devices, sensors and gadgets in day-to-day life, the buzzword Internet of Things (IoT) has become very popular.

In the context of the IoT environment, proper device authentication is important. Recently, Wang non monogamist al.

They insisted that their protocol non monogamist secure from various attacks in the open network. However, we show that Wang et al. To conquer these pipeline biogen, we design an improvement of Wang et al. We show that our protocol is secure against various attacks; specifically it is free from the attacks pointed out in Wang et al.

Through performance evaluation of our proposed protocol with the existing related protocols, we show that the proposed protocol is suitable for the IoT environment. Game theory approach for analyzing attack graphs by Khedoudja BOUAFIA, Lamia HAMZA Abstract: Many real problems involve the simultaneous security of computer networks and systems as it penetrates all areas of our daily lives.

The non monogamist of attack graph analysis is to be able non monogamist protect computer systems and networks against attacks related to them. In this flemish stew, we have proposed a new approach to analyzing attack graphs based non monogamist game theory in order to reduce network vulnerabilities.

This approach consists of turning a computer security problem into a two-player game and extracting the best strategies for each of the both of them.

The purpose of this work is to help administrator to take a good decision to better secure network by using game theory methods.
