content filter
Blocks inappropriate material
A content filter is a software or hardware tool that screens and blocks specific types of data or content based on predefined criteria.
Originally developed for email systems to block spam, modern content filters are used in web browsers, firewalls, and network systems to restrict access to websites, images, or files deemed inappropriate, harmful, or non-compliant with organizational policies.
They often rely on techniques like keyword matching, URL blacklists, or AI-driven analysis to identify and filter content.
The school installed a content filter to block gaming websites during class hours.
