Content Filtering is a process used to restrict the access of certain types of content on the internet. It works by blocking websites, applications, and other online content that is considered too explicit or inappropriate for certain age groups. Content filtering can be used to protect children from accidentally accessing adult content, as well as to prevent employees from wasting time at work browsing inappropriate websites. Content filtering typically relies on blacklists of banned sites and keywords that are used to flag and block potentially dangerous or offensive material. Additionally, some content filters can be customized according to user preferences, allowing parents or employers to decide which type of material should be blocked or allowed. In this way, content filtering helps promote safe and productive online experiences for all users.
