The Image encryption is the technique which can hide the sensitive text data. In the past times, various techniques has been proposed for image encryption which are broadly into wavelet transformation and discrete transformation, In this research paper, novel technique has been proposed which is based on textual feature extraction, selection and encryption. The GLCM algorithm is applied for the textual feature analysis, PCA algorithm is used for feature selection and block wise encryption is applied to generate final stego image. The proposed algorithm is implemented in MATLAB and it has been analyzed that it performs well in terms of PSNR and MSE.

Social media has found its place among all age groups. Nowadays, people find it easier to communicate using Social Media tool rather than talking directly to the other person. The time spent by individuals on social media is also a matter of concern. In our study we analyzed two major factors related to social media, one is the time spent by individual on social media and other one is sentiment analysis of communication. The study is conducted over two age groups over a period of one and half years. The result that youngsters are more involved in social media communication and the sentiment of communication is prominently negative.

Ad-hoc wireless sensor Networks (AWSN) has become a worldwide thought for the investigators and researchers for last few years. Ad-hoc networks are acts as decentralized type networks therefore it is used for a large number of applications like sensing, computing and processing techniques. In this paper we have used Zigbee application to make wireless connection with other devices. However some issues are associated with usage of ZigBee based Ad-hoc Wireless Sensor Networks including reduction in lifetime of nodes and Quality of services. Sensor nodes works on battery power and it is limited for each node; hence Zigbee based data routing and transferring to the base station are very important. In this paper, design network model has been evaluated by using various parametric factors including average End to End Delay, Throughput, Jitter and Total Packets Received with the help of AODV and DSR Routing Protocols. Latest version of Qualnet simulator has been used in this paper for simulation.

Today development of computer and information technology, computer and network have been very popular. At the same time, security is important to secure the data, especially in campus environment. A campus network faces, many challenges such as IP address allocation, network failure, detecting rogue system user and determining slowing network etc., This research is mainly targeted towards campus networks which deliver the required security and best performance. To reduce the maximum wastage of IP address space using VLSM technique. A network is divided into different subnets. This technique will improve the security and traffic isolation. To improve the network speed on campus area network using etherchannel technique. This technique increases the network speed and redundant path between two devices. To multiple smaller broadcast domain using VLAN. To Communicate different VLAN using Inter-VLAN technique. This technique is implemented using multilayer switch. To secure and control a network traffic using VLAN Access Control List (VACL). Secured network protects an institution from security attacks associated with network. A campus network has a number of uses, such as education, research, learning, supervision, e-library, result publishing and association with the external users. Network security prevents the campus network from different types of threats and attack. The system can efficiently control and handle the reliable operation of the campus network.

A branch of machine learning that attempts to model high-level abstractions in data through algorithms by the use of multiple processing layers with complex structures and nonlinear transformations is known as Deep Learning. In this paper, we present the results of testing neural networks architectures through tensorflow for various activation functions of machine learning algorithms. It was demonstrated on MNIST database of handwritten digits in single-threaded mode that blind selection of these parameters can hugely increase the runtime without the significant increase of precision. Here, we try out different activation functions in a Convolutional Neural Network on the MNIST database and provide as results the change in loss values during training and the final prediction accuracy for all of the functions used. These results create an impactful analysis for optimization and training loss reduction strategy in image recognition problems and provide useful conclusions regarding the use of these activation functions.

CAPTCHA methods used to separate amongst humans and bots programs. Captcha ask the user to play some task which is simple for humans to complete but troublesome for bots to finish. In this way Captcha go about as a defensive plan to avoid bots, in accessing the touchy data of sites and mishandle their online services. Bots behavior like humans and perform malicious action such as gathering e-mail addresses for spamming, blocking bulk number of tickets for an event. Use of existing chaptach technique annoyance for the users. CAPTCHA system should user friendly or enjoyable for users. In this paper we focused on the human power of understanding the humar or fun. Proposed the new CAPTCHA method that is emoji’s based CAPTCHA for identifying idioms. This new method is enjoyable or having fun for users as well as Emoji’s based Captcha is a technique to provide enhanced security for the web applications.
