The main objective of this project is to develop an application to find the best compression technique to store Muscat College students' photographs in less storage. MATLAB software will be used to develop a Graphical User Interface GUI application and implement two image compression techniques which are lossless compression using the DCT algorithm and lossy compression using the LBG algorithm.  The application shall allow the user to select and test a sample image by applying both these techniques for any student image he\she selects in order to compare the results by display the image after compression and the histogram to find which the most suitable compression technique is. Also, the application shall show the size of images before and after applying the compression process and show the compression ratio and relative data redundancy of compressed image/images. The main functionality is that the application shall allow the user to do bulk processing to apply image enhancement and image compression technique to enhance and compress all the photographs of students and store them in less space.

Internet of Things (IoT) is undoubtedly a well-known research area. Security on IoT communication services is the major challenge with advanced technology and devices. This paper mainly focusing on Perceptron layer based attacks and counter measures based on Effective Authentication System (EAS). This paper is ordered as outlining IoT Architecture, Types of Threats ,Perceptron Layer based attacks, sensor based communication services ,RFID mechanism ,Tag identify and verification by back end server and Hash based Effective Authentication System (EAS) to avoid pseudonym attacks .This paper proposes EAS as security measure by preventing privacy attack, pseudonym attack, location tracking and asynchronous attack.
