Content Filtering
Content filtering is a technique used to control or restrict access to digital content based on predefined criteria, such as keywords, categories, or user behavior. It is commonly applied in web filtering, email security, and social media moderation to block inappropriate, harmful, or unwanted material. This process helps organizations and individuals enforce policies, protect against threats like malware or phishing, and maintain compliance with regulations.
Developers should learn content filtering when building applications that require user safety, data protection, or regulatory adherence, such as parental control software, corporate networks, or online platforms with user-generated content. It is essential for implementing features like spam detection, hate speech moderation, or access control in educational or workplace environments to prevent exposure to malicious or offensive material.
