Abstract The word “Steganography” was basically derived from the Greek words with the meaning “covered writing.” This paper presents some of the main adaptive image steganography approaches. Many algorithms have been presented; in almost all the algorithms the approach is to embed the secret data in the images. Here we are discussing about adaptive steganography which is based upon spatial domain and frequency domain with an additional layer of mathematical model. The embedding and extracting processes of the algorithms have been discussed General Terms: Adaptive steganography, security, image processing

An Implementation of Maintaining Database and Generating Report using K-Means Algorithm Prashant P. Kulkarni, Dipali H. Patil, Akshata V. Ghodke, Tejashri S. Pansare, Javed I. Tamboli* Department of Information Technology, Rajarshi Shahu College of Engineering, Pune, India

Abstract This is a sponsored project from Electronics Testing and Development Center (ETDC), a government organization which works under Standardization Testing and Quality Certification (STQC), Government of India, and provides quality assurance services in the area of electronics and IT through countrywide network of laboratories and centers. Automation of testing and calibration of electronic instruments will assist ETDC in providing these services in a better way by generating report and maintaining history of customer and electronic instruments on web-based paperless system. For generating report, the authors have applied data-mining algorithm as k-means algorithm.

Keywords: K-means algorithm, data mining

Optimized Test Suites with Small Code Coverage in Software Testing B V V Anusha*, A.Vanathi IT Department, Aditya Engineering College, Surampalem, Kakinada, East Godavari (Affiliated to JNTUK) Abstract A common scenario in software testing is to test the data is to be generated and tester manually adds test oracles.It meausured using code coverage and fundamental problemwith common apporach is coverage the goals and how an of them are feasible. In this whole test suites are evovled covering all goals at same time.Its effectiveness not added by number of infeasible targets in code.It has a novel approach in approach Evosuote Tool and it achieved upto 188 times branch coverage in traditional approach targeting single branch strategy with upto 62% samaller test suites.In software testing many testsuites are used to debug a program to over come the testsuites Evosuite Tool was implemented tocoverage goala as well as But the problem is targeting one coverage goal at a time is not feasible and code coverage is also high. In order to overcome this problem generating new test suites with the help of Evosuite tool which covering all coverage goals as well as coverage code is small.

Keywords: Search based software engineering, branch coverage, infeasible goal, collateral coverage genetic algorithm.

Pattern Discovery for Text Mining Ravindra Changala*, D Rajeswara Rao, Vidyullatha P, Annapurna Gummadi KL University, CSE Department, Vijayawada, India

Abstract Text mining refers to the process of extracting interesting, non-trivial information and knowledge from unstructured text. The challenging issue is to find accurate cognition or characteristics in text documents to help users to find what they want. Many term-based methods solved this but later suffered from the problems of polysemy and synonymy where polysemy means a word has multiple meanings and synonymy is multiple words having the same meaning. Later phrase-based approaches served well, as phrases may carry more “semantics” like information. The performance of it decreases due to phrases having inferior statistical properties to terms, low frequency of occurrence, and large numbers of redundant and noisy phrases among them. To overcome this pattern miningbased approaches have been proposed, which include the concept of closed sequential patterns, and pruned non-closed patterns. These pattern mining-based approaches worked with effectiveness. The contradiction is people think pattern-based approaches are significant alternative, but less improvements is made for the effectiveness compared with term-based methods.
