  • Encrypted templates prevent unauthorized access and misuse of fingerprint data.

4. Database Storage

  1. Template Storage:
  • The encrypted template is stored in a secure database.
  • This could be a local storage system or a cloud-based solution.
  1. Indexing:
  • Templates are indexed for fast retrieval during identification or verification processes.
  • Proper indexing aids in efficient searching and matching.

5. Matching Process

  1. Template Comparison:
  • For identification, a new scan is compared against the stored templates.
  • The system calculates similarity scores between the scanned fingerprint and stored templates.
  1. Threshold Check:
  • The similarity score is checked against a pre-defined threshold.
  • If the score exceeds the threshold, a match is confirmed.
  • If not, the search continues or prompts a rejection based on the configuration.

6. Outcome

  1. Verification:
  • In verification mode, the system confirms the identity by matching the scanned fingerprint with a specific template.
  • Typically used in scenarios requiring access control.
  1. Identification:
  • In identification mode, the system searches a database for a matching template.
  • Useful in law enforcement and large-scale identification applications.

Fingerprint recognition for live scan offers a reliable and secure method for verifying and identifying individuals.

By understanding the steps involved—from scanning to matching—you can appreciate the sophistication and effectiveness of this biometric technology.
