1. Anonymity: Masks can conceal one's identity, providing a sense of security and privacy.
2. Protection: Masks can protect against physical harm, like in the case of gas masks or riot gear.
3. Disguise: Masks can be used to disguise oneself, potentially for security purposes like undercover operations.
4. Access control: Masks can be used to grant or deny access to secure areas or events.
5. Surveillance: Masks can be used to conceal security cameras or other surveillance equipment.
6. Encryption: Masks can represent encryption, hiding sensitive information and keeping it secure.
7. Physical security: Masks can be used to secure physical objects, like locking masks for equipment or valuables.
8. Cybersecurity: Masks can symbolize cybersecurity measures, like hiding IP addresses or encrypting data.
