Due to the prevalence of the COVID-19 epidemic around the globe, children were compelled to engage in remote learning through online platforms, hence mobile phone has become one of their predominant devices. Mobile device with Internet access offers a major outlet for education, entertainment, and social connection, but this combination can lead to several significant bad sequences such as online exploitation, harmful addictions, and other negative impacts of online social networking. To address harmful effects, parental controls are becoming more crucial, yet Sri Lankan parents are less aware of this. Consequently, this study proposes a parental control system to monitor their child’s activities. Android, Microsoft Azure, Java, Python, OpenCV, MySQL, and FastAPI are among the most prominent technologies utilized in the proposed application’s development. The suggested approach focuses primarily on the Sri Lankan context and aims to enhance parental digital literacy while safeguarding children from cyber threats. Yielded results showed the proposed mobile application for the identification of toxic words, drugs & alcohol content, game character images, and Instagram Sinhala comments severity as 94%, 95%, 97%, and 55% respectively in controlled experiments.

Availability of real-time public train transportation information can help to improve the commuters' transportation needs. Most of the time the guaranteed information is only supported in a closed system. Due to the administrative issue, there is no infrastructure to provide real-time data to any interested party. This paper proposed a framework that aims to provide a multiple-sourced crowdsourcing approach to generate Real-time Public Train information. The proposed system will enhance the accuracy as well as efficiency of the current system to provide accurate real-time train Status by crowdsourcing train location GPS (Global Positioning System) data from the passenger's smartphones. The tracing data are used to update the arrival/departure time using a predictive data source. The basic information is collected and distributed of each train route, stops and schedules. The `User Report Information' includes information related to trains and can be shared among the other interested parties through our System.
