Adolescent online safety has become a great concern in today's digital landscape, necessitating innovative approaches to address online risks, such as cyber-bullying, cyber-stalking, exposure to inappropriate content, internet addiction, and more. This systematic review paper aims to explore how technology can contribute to enhancing online safety for adolescents. By conducting an extensive survey of 21 research papers published between 2015 and 2023, the study aims to identify and assess prevailing trends, challenges, and potential applications of modern technology in addressing online risks specific to the adolescent demographic. The paper offers insights into the efficacy of existing technological strategies and underscores prospective research paths for the development of resilient online safety measures tailored for adolescents. The review covers various technologies such as robust content filters, AI-driven sentiment analysis, gamified educational programs for online safety, adaptive parental control technologies, and secure communication platforms. These strategies aim to address challenges like privacy concerns, over-restriction, rapid evolution of online platforms, and digital literacy disparities. The findings highlight the importance of comprehensive education programs, adaptive technological solutions, tailored support, and empowering adolescents in ensuring continuous enhancement of online safety.
