The world is changing rapidly due to information technology, and all the people around the world are busy with their jobs, and business, adjusting to this race. Now, parents are giving more time at their business, office, and jobs, instead of passing the time at home, but they always get worried and scared about their children due to abuse of Information Technology and the country's law and order situation. So, parents are wanted to track and monitor their child's activities and location from anywhere to resolve their pressure. But is not possible for every parent to monitor their child physically due to many reasons. This paper presents a system that will help parents monitor their child activities from anywhere using a mobile phone to solve the problem. This android app uses global positioning system (GPS) and mobile services to find the child location and secretly stored all the call logs, hort message service (SMS) logs, contact lists, and accurate locations without knowing the children. Children assume that they are using Facebook, browsing the net or watching videos from youtube. It will not hamper any activities of the child. Parents can check all the activities of children using this app.

PRO-VAS: utilizing AR and VSLAM for mobile apps development in visualizing objects

“…For the development of the app, the main components are identified, where are the AR, VSLAM, point plane, RGB-D mapping and markerless tracking method. Other important context is that the processes involved in the app should be helping the users to access the functions effectively [2], [3] for user satisfaction [15].…”

“…Everything is on the fingertips and it makes the user have full control on what they want and desire for.

Our paper proposed an app that can visualize objects and provides mapping of the scene.…”

Video steganography using 3D distance calculator based on YCbCr color components

“…Most methods of steganography are conducted by including secret messages, with less distortion in the digital medium [4], [8], [41], [53]- [60], [11], [12], [23], [28], [29], [33], [34], [39]. Therefore, to maintain the quality of the digital medium, it provides limited security capability for any limited medium [11], [61], [62], also by considering the use of a method to successfully detect the hidden message in the digital medium by the recipient [4], [11], [12], [23], [33], [39], [41], [63], [64].…”
