Abstract: This paper deals with the techniques that are used to prevent the web applications from web security vulnerabilities caused by hackers which leads to the misusage of data. Web services and applications have increased in both popularity and complexity over the past few years. Daily tasks, such as purchasing, banking, travel, and social networking, are all done via the web. Web services have always been the target of attacks. These attacks have recently become more diverse, as attention has shifted from attacking the front end to exploiting vulnerabilities of the web applications in order to corrupt the back-end database system. We present Double Guard, a system used to detect attacks in multitier web services.

Abstract: Embedded products have different types of display screens like LCD, Touch screen, CRT etc. For automating the development testing of such devices, we need to recognize the text displayed on it using a camera. It is always a challenge to recognize the LCD display screen using OCR engines. Due to the custom display nature of these LCD controllers as well as the small font size, character recognition is a complex job. Traditional way of recognizing such screens uses template matching techniques. Such image matching techniques take precious time which drastically increases depending upon the number of characters and their size. In this paper, we are going to discuss an algorithm, which helps to recognize such small text in an accurate and speedy manner using low cost resources like webcam and open source software.

Title : Video Surveillance for Effective Object Detection with Alarm Triggering
Country : India
Authors : B. Priyanka, A. Ramya, J. Sri Katheswari

Abstract: This paper presents a novel algorithm for detection and segmentation of foreground objects from a video which contains both stationary and moving background objects and under- goes both gradual and sudden "once-off" changes with fixed background and static cameras. Our method achieves complete detection of moving objects by involving three significant proposed modules: a background modeling (BM) module, an alarm trigger (AT) module, and an object extraction (OE) module For our proposed BM module, a unique two-phase background matching procedure is performed using rapid matching followed by accurate matching in order to produce optimum background pixels for the background model. Next, our proposed AT module eliminates the unnecessary examination of the entire background region, allowing the subsequent OE module to only process blocks containing moving objects. And the alarm triggers while a new object enters into the frame, the foreground information and background information are identified using the reference frame as background model . Here , both visual as well as quantitative measures show an improved performance and the scheme has a strong potential for applications in real time surveillance.

Abstract: A mobile WSN is considered as a collection of wireless mobile nodes and a base station forming an ad-hoc network. This type of network is used in various areas; such as underwater and underground. Each node has a limited energy and a random mobilization. Since the energy consumption is a very important factor, the Hierarchical protocols can solve this problem for instance the LEACH protocol. W-LEACH is a LEACH extension which extends the network lifetime but this protocol uses sensor location to organize the network so it is not effective in an area where the location of nodes is impossible with mobility. In this paper, we improve an old algorithm (W-LEACH) to a new protocol called W-LEACH Decentralized to increase network lifetime without the use of maps. Besides, we are going to compare this protocol with LEACH in term of network lifetime and energy dissipation using Network Simulator.

Country : India
Authors : Mr. R. Thanigaivel, Mr. S. A. Ramesh kumar
: 10.9790/0661-16274044    logo
Abstract: The reverse dictionary identifies a concept/idea/definition to words and phrases used to describe that concept. You can enter a single word, phrase, or a few words to get the correct meanings for that sentence. The proposed concepts similarity is applied using similarity for computing the relevancy between concepts verses and the documents or verses in English collections. Reverse Dictionary (RD) is a non alphabetic order dictionary. We present a set of algorithms and the results of a set of experiments showing the retrieval accuracy of our methods and the runtime response time performance of our implementation. Our experimental results show that our approach can provide significant improvements in performance scale without sacrificing the Quality of the result. Our experiments comparing the quality of our approach to that of currently available reverse dictionaries show that of our approach can provide significantly higher quality over either of the other currently available implementations.

Abstract: Now days, most of the people find the information over the internet by visiting various number of web pages and also by following the links under those web pages. A user has the ability to browse for data through the web pages he/she requires by following these web links. Even though, if the web page requested is not made public. There are various resources over the internet; most of them are hidden behind the database. Because of it, the user is only able to access it after making a query in to the database. With the help of search engines, this problem of finding required and necessary data is been resolved. This paper presents a method to retrieve such hidden data from web.

Title : Measuring Maintainability Index of a Software Depending on Line of Code Only
Country : Iraq
Authors : Nahlah M.A.M.Najm
: 10.9790/0661-16276469    logo
Abstract: Maintainability Index (MI) has been proposed to calculate a single number that expresses the maintainability of a system. MI is calculated as a factored formula consisting of Lines of Code (LOC), Cyclomatic Complexity (CC)and Halstead Volume (HV). In this paper, we present a new method to find MI with respect to LOC only. To validate the method Measuring Maintainability Index Software (MMIS) is developed, that first finds MI with respect to (LOC, CC, and HV); secondly find MI with respect to LOC only. As the result has been compared they were closed but the new method was easy to understand, fast to count, and independent on the program language. In addition to many well-known programs, the MMIS was used to test itself and the result demonstrates that the program used to calculate MI value with respect to LOC only tend to be maintainable while the lexical analyzer the major step in calculating MI with regard to (LOC, HV, CC) is difficult to maintain.

Abstract: Patient Health Record (PHR) is a complete Patient related health data, which is getting stored in cloud computing to gain cost benefit and better access control. In maintaining PHR, cloud computing plays an inevitable role, since small hospitals and physicians are not affordable to maintain own servers to keep PHRs for cost and security reasons . Providing accessibility to variable stake holders like Patients, Physicians, Hospitals and Insurance Providers, become a tedious process in private individual servers with encryption mechanisms. Cloud solution ensures that PHRs ' availability to the necessary stake holders at any point of time. In any country , there are laws which governs to maintain privacy of patient health records, and hence maintaining PHRs in cloud are subjected to privacy concerns and high risk of getting exploited. There are various encryption schemes exist to preserve PHR's security and privacy in Cloud computing. In this paper, we propose a secure PHR accessing scheme for dynamic environment to preserve privacy in semi trusted cloud servers.

Abstract: The amount and variety of data in natural sciences increases rapidly. Data abstraction, data manipulation and pattern discovery techniques are of great need in order to deal with such large quantities. Integration between different sources of data is also of major interest, as complex relations may arise. Biology is a good example of a field that provides extensive, highly variable and multi-sources data. The scope of these investigations has now expanded greatly owing to the development of high throughout sequencing techniques and novel statistical and computational methods. These methods require easy-to-use computer programs. We have developed a new software package, molecular genetics analysis to integrate their diverse data and tools under Common Graphical User Interfaces (GUIs) by using BLAST, FASTA data searches. One of the most exciting things about being involved in computer programming and biology is that both fields are rich in new techniques and results. The illumina is sequence analyzer in Next Generation Sequence Technology.
