Biometric System Properties

Universality: Every individual should possess the trait used for identification.
Uniqueness: The trait should be unique enough to distinguish individuals within the relevant population.
Permanence: The trait should remain relatively stable over time, with minimal changes affecting the matching algorithm.
Measurability (Collectability): The trait should be easily acquired and measured. The acquired data should be suitable for processing and feature extraction.
Performance: The technology must be accurate, fast, and robust for reliable results.
Acceptability: The technology must be acceptable and comfortable for users, who should be willing to provide their biometric data.
Circumvention: The trait should be difficult to imitate or substitute, minimizing the risk of unauthorized access.

Biometric System Functionalities

Verification (Authentication): This function verifies a user's claimed identity by comparing their biometric data to a stored template. It determines if the user is who they claim to be (one-to-one match).

Biometric System Errors

Biometric systems rely on the uniqueness and permanence of the underlying biometric trait.
Uniqueness: A biometric identifier is considered unique if any two individuals can be differentiated based on it.
Permanent: The trait should remain relatively stable over time.
