Fingerprint data is typically stored as digital representations, conforming to standardized formats for interoperability and security.
The key fingerprint formats are ANSI 381 and ISO 19794-2. These are biometric template formats used to save fingerprint data. Let's explore them in more detail:
- ANSI 381: This standard, developed by the American National Standards Institute, defines the format for exchanging fingerprint information. It focuses on ensuring compatibility between different fingerprint recognition systems.
- ISO 19794-2: This is an international standard that specifies the data format for fingerprint templates. It provides a common framework for representing and exchanging fingerprint data, facilitating interoperability across various biometric systems.
In essence, these formats outline how fingerprint characteristics (minutiae points, ridge patterns, etc.) are encoded and stored digitally. This allows different fingerprint readers and matching algorithms to process and compare fingerprints consistently.
