Types of Door Locks

• Traditional Padlocks
  • Easily defeated and offer minimal protection
• Basic Door Locks
  • Vulnerable to simple techniques like lock picking
• Modern Electronic Door Locks
  • Utilize various authentication methods for enhanced security
  • Authentication Methods:
    • Identification Numbers
      • Require entry of a unique code, providing a balance of security and convenience
    • Wireless Signals
      • Utilize technologies like NFC, Wi-Fi, Bluetooth, or RFID for unlocking
    • Biometrics
      • Rely on physical characteristics like fingerprints, retinal scans, or facial recognition for authentication
      • Biometric Challenges
        • False Acceptance Rate (FAR)
          • Occurs when the system erroneously authenticates an unauthorized user
          • Lower FAR by increasing scanner activity
        • False Rejection Rate (FRR)
          • Denies access to an authorized user. Increasing sensitivity can increase FRR
        • Crossover Error Rate (CER)
          • A balance between FAR and FRR for optimal authentication effectiveness
• Some electronic door locks use multiple factors, such as an identification number and fingerprint to increase security
• Cipher Locks
  • Mechanical locks with numbered push buttons, requiring a correct combination to open
  • Commonly used in high-security areas like server rooms
• Secure entry areas in office buildings, often use electronic access systems with badges and PINs for authentication
