Abstract: Visual Cryptography is a special type of secret sharing deterministic and random grid visual cryptography The XOR – based visual cryptography (VC) is a possible methodology to work out on the poor visual quality without darkening the background. This paper focus on some technique as , Extended visual cryptography scheme (EVCS) for general assess structures, RG-based visual secret scheme (VSS), Adaptive region incrementing XOR- based VC ,Compared relation in deterministic and random visual cryptography and XOR based visual cryptography. The new scheme propose for multiple share image using XOR and random grids is proposed which will encrypt and decrypt algorithm by secrete images recovered quality improvement.

Abstract: Embedded systems are growing by leaps and bounds in many domains such as automobiles, industrial control, mobile phones etc. As these devices have started integrating in our daily life we need to look into for some critical measures that is security of these embedded systems. In this paper we look at existing threats and vulnerabilities in embedded systems. We envision that the findings in this paper provide a valuable insight of the threat landscape facing embedded systems. The knowledge can be used for a better understanding and the identification of security risks in system analysis and design.

Abstract: Users store vast amounts of sensitive data on a cloud. Sharing sensitive data will help enterprises reduce the cost of providing users with personalized services and provide value-added data services. However, secure data sharing is problematic. Security is one of the most difficult task to implement in cloud computing. Different forms of attacks in the application side and in the hardware components. This paper proposes a framework for secure sensitive data sharing in cloud, including secure data delivery,....

Abstract: Classification of Astronomical Data having large database is a troublesome activity. Data mining decision tree based techniques are applied for classification of star. The objective of the work is to evaluate the effectiveness of random forest on astronomical object classification. Random forest is an ensemble based classifier method where each classifier is decision trees. Results shows that ensemble method performs better as compared to single tree based classifier.

Abstract: Data Integrity is the most important service of cryptography. Hash functions are used to check the integrity of the file. Hash functions are useful, if the active attack is performed by the attacker. For the secured communication before sending any file though the unsecured network the hash value of any file or message is found out using hash function. After receiving the file by the recipient again the hash value of the received file is calculated....

Abstract: This is a survey paper describes different types of algorithms for Reversible Data Hiding (RDH). Reversible data hiding can be defined as an approach where the data is hidden in the host media such as image, audio and video files. Reversible Data Hiding (RDH) or lossless data hiding, is a method by which the original cover can be lossless restored after the embedded information is extracted. Many RDH techniques have been developed. This paper summarizes and reviews these techniques. Previous literature has shown that difference expansion, interpolation technique...
