Study Notes

Mobile Authentication Apps

  • Implement a one-time password generator using the "Time-based one-time password (TOTP)" algorithm
  • Does not require a network connection for operation
  • Can be used with multiple accounts simultaneously
  • More secure than authentication code due to dynamic password generation
  • Disadvantages:
    • Susceptible to phone loss or theft
    • Vulnerable to malware installation by attackers
    • Risk of users revealing secret codes to attackers

Biometric Authentication

  • Authenticates individuals based on unique physical characteristics
  • Based on pattern recognition technology
  • Technically complex and expensive compared to passwords and tokens
  • Physical characteristics used for biometric authentication:
    • Facial characteristics
    • Fingerprints
    • Hand geometry
    • Retinal pattern
    • Iris
    • Signature
    • Voice
