Several technologies are used to enhance data security, including:
1. Blockchain: This decentralized technology ensures data integrity and security by creating immutable records. 2. Artificial Intelligence: AI can detect and respond to security threats in real-time, reducing the risk of breaches. 3. Cloud Security: Cloud service providers offer advanced security features to protect data stored in the cloud. 4. Multi-Factor Authentication: This adds an extra layer of security by requiring multiple forms of verification.
