Which biometric approach analyzes patterns in user behavior such as keystrokes, signatures, and voice?

• A. Biometric Technology
• B. Behavioral Biometric Technology
• C. Physical Biometric Technology
• D. Encryption

Answer: (B)

Behavioral biometric technology examines the way a person acts rather than their physical traits. Keystroke dynamics look at timing between key presses, how long a key is held, and typing rhythm. Signature dynamics analyze how the signature is produced—the speed, stroke order, and pressure. Voice patterns capture aspects of speech such as cadence, tempo, and intonation. These behavioral cues are unique to an individual and can be monitored continuously as someone uses a system, enabling ongoing authentication and detection of anomalies. The other options don’t fit because they refer to physical traits like fingerprints or iris scans, or to a non-biometric method altogether like encryption.
