Patented Biometric Access – Smarter, Safer, Password-Free
FinPin’s patented technology redefines biometric authentication by replacing traditional passwords with fingerprint-based access solutions. The concept was partly inspired by Apple’s introduction of a fingerprint reader on the iPhone. FinPin saw this as a key opportunity to leverage users’ personal smartphones as part of an enhanced multi-factor authentication (MFA) process—verifying not only (1) what the user knows (e.g., a password), but also (2) what the user has (e.g., their phone), and (3) who the user is (e.g., their biometric fingerprint).
Triggered by an External Application
An internet-based application requests user authentication via a secure connection to the authentication service.
Authentication Starts on Your Device
The user’s mobile terminal receives a transaction request and prompts for a biometric input (e.g., fingerprint).
Private Key Access Only Upon Match
The mobile device locally verifies the biometric input and, if valid, unlocks a private key stored securely on the device.
Transaction Identifier Is Signed and Sent Back
The transaction identifier is digitally signed using the private key and returned to the authentication service.
Final Check Before Access is Granted
The authentication service verifies the signature and confirms identity to the requesting application if authentic.
Scalable and Redundant by Design
Authentication can be handled by multiple redundant services, making the system robust and scalable for a wide range of applications—from websites to IoT.
