The previous research has focused on quick and efficient generation of wrappers; the development of tools for wrapper maintenance has received less attention. This is an important research problem because Web sources often change in ways that prevent the wrappers from extracting data correctly. Present an efficient algorithm that extract unstructured data to structural data from web. The wrapper verification system detects when a wrapper is not extracting correct data, usually because the Web source has changed its format. The Verification framework automatically recovers data using Dimension Reduction Techniques from changes in the Web source by identifying data on Web pages. After apply wrapped data to One Class Classification in Numerical features for avoid classification problem. Finally, the result data apply in Top-K query for provide best rank based on probabilities scores. Wrapper verification system relies on one-class classification techniques to beat previous weaknesses to identify the problem by analysing both the signature and the classifier output. If there are sufficient mislabelled slots, a technique to find a pattern could be explored.

Diabetic retinopathy is a complication of diabetes causing progressive damage to the retina, located at the back of the eye, potentially leading to clouded vision or blindness. Disease signs may be visualized by Optical Coherence Tomography (OCT) and include formation of new and weaker blood vessels, fluid accumulation, exudates and changes to Retinal Vascular Geometry (RVG). Presence of these indicators can provide information as to the stage of the disease. Image-processing strategies are applied for the automated detection, segmentation, extraction, classification toward likelihood estimation of progression of diabetic retinopathy to visual biomarkers present in OCT, using time-sequenced data in the early stages of the disease. Gabor and Savitsky-Golay filtering enables extraction of the vessel map and fuzzy control for segmentation of hard exudates. Feature data are extracted using bounding boxes, vector map and connected component methodology for binary decision tree classifier construction, training and testing. Feature values comprising classifier nodes include: exudate features of compactness, area, convexity and form factor, in addition to vessel features: width, elongation, bifurcation angles, form factor and solidity. Classifier accuracy is 93.3%, with 6.7% misclassification and 0% false-negative classification. Automated image processing of diabetic retinopathy is achieved with high classification accuracy for the extraction of vessel map and hard exudate biomarkers from OCT. Application of smoothing algorithms and removal of vessel map shadows may further improve classification accuracy

stract: Third-party apps are a major reason for the popularity and addictiveness of Online Social Network. However little is understood about the characteristics of malicious apps and how they operate. Malicious apps are much more likely to share names with other apps, and they typically request fewer permissions than benign apps. We will propose MADE – a Malicious Application Detector and Evaluator that will do two major things. Firstly, we will find the malicious apps often share names with other apps, and they typically request fewer permissions than benign apps. Secondly, leveraging these distinguishing features, we show that MADE can detect malicious apps with certain accuracy. We will also highlight the emergence of appnets and will keep continue to dig deeper

Bit-Exchange Encryption is the cryptographic conducting tool to assurance data owners enduring control above their data in public cloud storage. The earlier ABE plans include one and only power (Authority) to keep up the entire trait (Key) set, which can carry a solitary (single) point bottleneck on both safety and execution. In this way, some multi- power (Multi-Authority) plans are proposed, in which various powers independently keep up disjoint attribute subsets. In any case, the single-point bottleneck issue stays unsolved. In this paper, from another point of view, we conduct a threshold multi-authority CP- ABE access control plan for open distributed storage, named TMACS, in which various powers together deal with a uniform characteristic set. In [9] TMACS, taking advantage of (t; n) limit mystery sharing, the expert (Master) key can be shared among numerous powers, and a legitimate client can produce his/her mystery (Private) key by cooperating with any t powers. Security and execution investigation results demonstrate that system is not just undeniable secure when not as much as t powers are traded off, additionally dynamic when no not as a great deal as t powers are alive in the framework. Besides, by proficiently joining the customary multi-power plan with system, we build hybrid one, which fulfils the attributes originating from various authorities and accomplishing security.

The body area network (BAN) technology is one of the core technologies of IOT developments in healthcare system, where a patient can be monitored using a collection of tiny-powered and lightweight sensor nodes. However, the development of this new technology in healthcare applications without considering security makes patient privacy vulnerable. In this paper, at first, we highlight the major security requirements in BSN-based modern healthcare system. Subsequently, we propose a secure IoTbased healthcare system using BSN, called BSN-Care, which can efficiently accomplish those Requirements.

The paper discuses about the performance of digital modulation schemes – BPSK, QPSK and QAM using MATLAB. The performance of these schemes is evaluated by finding the bit error rate (BER) on AWGN and Rayleigh channels. Initially a MATLAB code is generated and the performance of these modulation schemes BPSK,QPSK and QAM is evaluated by finding BER and signal to noise ratio over AWGN and Rayleigh fading channels. Later a simulation model is created using Simulink for these modulation schemes and its performance is evaluated on AWGN channel.

Big data is a popular term used to describe the large volume of data which includes structured, semi-structured and unstructured data. Now-a-days, unstructured data is growing in an explosive speed with the development of Internet and social networks like Twitter,Facebook & Yahoo etc., In order to process such colossal of data a software is required that does this efficiently and this is where Hadoop steps in. Hadoop has become one of the most used frameworks when dealing with big data. It is used to analyze and process big data. In this paper, Apache Flume is configured and integrated with spark streaming for streaming the data from twitter application. The streamed data is stored into Apache Cassandra. After retrieving the data, the data is going to be analyzed by using the concept of Apache Zeppelin. The result will be displayed on Dashboard and the dashboard result is also going to be analyzed and validating using JSON.

Today internet security is a serious problem. For every consumer and business that is on the Internet, viruses, worms and crackers are a few security threats. There are the obvious tools that aid information security professionals against these problems such as anti-virus software, firewalls and intrusion detection systems, but these systems can only react to or prevent attacks-they cannot give us information about the attacker, the tools used or even the methods employed. Given all of these security questions honeypots are a novel approach to network security and security research alike. It is a resource, which is intended to be attacked and compromised to gain more information about the attacker and the used tools. It can also be deployed to attract and divert an attacker from their real targets. Honeypots is an additional layer of security. Honeypots have the big advantage that they do not generate false alerts as each observed traffic is suspicious, because no productive components are running on the system. The levels of interaction determines the amount of functionality a honeypots provides that is low and high interactions.
