Introduction
The term “Internet safety” encompasses a set of troubles which can be, both at once or indirectly, related to the physical and psychological well-being of Internet users. Also referred to as “online safety,” “virtual safety,” or “e-safety” this idea is associated both with the dangers people face on-line and with the methods they can guard themselves in opposition to the one’s dangers. A big frame of studies inside this area is dedicated to the safety of children and adolescents. One reason for this specific focus is the fact that young people and children are the most active Internet users. Being online offers them a whole range of opportunities, but at the same time this may confront them with several risks.
Despite the very significant number of studies that have been carried out concerning those risks, enhancing children’s Internet safety remains a challenge. In part, that is due to the fact definitions of phrases and classes applicable to online protection (such as “cyber bullying”) frequently vary, making the assessment of information and findings amongst sources imprecise.
