	CyberSafety: Making Internet Safer for its Users The theme of cybersafety is an important emerging research topic that manifests itself daily as users navigate the Web and networked applications. Examples of cybersafety issues include cyberbullying, cyberthreats, using Internet to recruit minors for nefarious purposes, and posting objectionable content in video chats. These issues have a direct impact on placing trust in the services provided via the Internet. They impact the users negatively in that the users are exposed to undesirable and potentially harmful content. They also impact the service providers negatively by reducing the quality of the service that they provide.
