AI Technical Summary
Existing authentication systems fail to differentiate between voluntary and coercive user authentication, leading to potential abuse and security vulnerabilities.
A biometric authentication system that includes a biometric authentication unit, analysis component for detecting coercive situations, and reaction logic for adjusting system responses, incorporating behavioral and contextual evaluations.
The system effectively identifies coercive situations and prevents abuse by implementing additional security measures, such as blocking release or triggering covert alarms.
Abstract
Description
Technical field:
[0001] The invention relates to an authentication system, in particular for security-critical applications such as payment transactions, access systems, mobile devices or vehicle controls. State of the art:
[0002] Known authentication systems are based on knowledge (PIN), possession (card), or biometric characteristics (fingerprint). These systems only verify a user's identity, not whether the authentication is voluntary.
[0003] This creates the risk that a user may be forced to unlock features. Problem statement:
[0004] The aim is to create a system that: • Recognizes coercive situations • Abuse prevented despite correct authentication • Implements additional security measures4 Solution:
[0005] The system includes: • A biometric authentication unit • An analysis component for detecting coercive situations • a reaction logic for adjusting the system response
[0006] In addition to identity, behavioral and usage patterns are also evaluated. Examples of implementation: • Alternative finger for triggering a silent alarm • Analysis of pressure, time, and movement patterns • Context-dependent evaluation (location, device) System reactions • Blocking the release • Restricted release • Covert alarm notification
Claims
[1] System for authenticating a user using a hardware-bound security card with biometric capture. characterized by that the security card or an associated system is set up. • In addition to the user's identity, also capture characteristics of the authentication process, • To analyze these characteristics with regard to a possible state of compulsion, • And to trigger a modified system response depending on a detected or suspected state of distress, the modified system response including in particular a blocking, a delayed release, a restricted release or a covert alarm message. [2] System according to claim 1, characterized by that an alternative biometric authentication feature is provided which, when used, triggers a covert alarm function. [3] System according to claim 1 or 2, characterized bythat the authentication process is analyzed based on pressure, time, or movement patterns. [4] System according to any one of the preceding claims, characterized by , that in the event of a recognized coercive situation, covert communication takes place with an external system. [5] System according to any one of the preceding claims, characterized by , that the modified system response includes an apparent release while the actual function is simultaneously restricted or blocked. [6] System according to any one of the preceding claims, characterized by that the system is integrated into a security card, a mobile device, a payment system or a vehicle.
