Biological identification lock

Abstract

Biometric identification system in the form of a segmented lock, characterized in that it is activated by the physical insertion of a human finger and enables multidimensional biological verification along the length of the finger.

Description

1. Technical field

[0001] The invention relates to a biometric identification system according to international patent classifications G07C 9 / 00 and G06K 9 / 00. The system comprises both hardware-based and software-based components for real-time biometrics, access control, and digital identity verification. It serves for secure authentication in security-critical, institutional, and public sectors. 2. State of the art

[0002] Known biometric systems are based on area-based recognition of fingerprints or facial features. These systems use static templates, are susceptible to forgery and data leaks, and do not offer dynamic, segmented verification. Furthermore, they lack liveness detection and analysis of the skin's depth structure, which significantly limits security. 3. Objective of the invention

[0003] The goal is to develop a castle that: • Can only be activated by living biological tissue • Fingers are divided into four segments along their length • Generates an individual, non-reproducible biological code • Serves as a digital identity, access key, transaction authorization and for logging access processes • Dynamic rights management within networked systems enables 4. Structure and Function

[0004] The lock is circular and ergonomically designed for right-handed users. Inside is a transparent sensor glass surface with four active segments: The sensor segments consist of capacitive, optical, and thermal units that are only activated by living tissue. When the finger is fully inserted, a laser-based biological line is generated along the length of the finger – from the nail tip to the base of the finger. This line serves as the basis for a biometric hash code that is generated in real time. 5. Comparison and advantages

[0005] Compared to existing systems, the invention offers: • Segmented, dynamic detection instead of area-based, static detection • Protection against silicone copies, dead tissue and forced removal • Real-time generation of code that is not stored but generated anew for each application. • Combination of physical presence, biological activity, and digital identity • Adaptive security through context-dependent approval and situational blocking based on stress indicators 6. Data integration and identity database

[0006] The system enables the collection and storage of: • Time and place of access • User's biometric code • Linking to digital identities (bank account, employment status, access rights)

[0007] The database can be used to generate attendance statistics, access histories, and for behavioral analysis – for example, in the case of security-relevant incidents or for forensic evaluations. At public events, attendance can be automatically recorded – without tickets, cards, or manual checks. 7. Network-based multi-person verification with multi-complex biocode

[0008] The biological identification lock can be connected to a network with multiple verified users. This generates a multi-complex biocode consisting of several biological algorithms – e.g., fingerprint, tissue structure, circumference, temperature profile, and temporal sequence. Collective authorization • Access to sensitive areas (e.g., bank vaults, museum safes, military archives) is not possible for a single individual. • Multiple verified users must submit their biological data simultaneously or sequentially. • Access is only granted if all required biocodes match in real time and the network confirms authorization. • Release can also be delayed – within a defined time window. Network communication • Only verified devices and people will be allowed. • Biocodes are transmitted in encrypted form • Real-time status messages are sent to higher-level authorities (e.g., security management, control center) 8. Multifunctional biocode with multi-finger recognition

[0009] The biological identification lock can optionally be configured to store and process 6 to 10 fingerprints of a user. This generates a combined biocode consisting of several finger segments – e.g., right thumb, left little finger, right index finger, etc. How it works • User registers multiple fingers in the database • During verification, two or more fingers are inserted sequentially. • Each finger is segmented for detection (as in the main system: S1-S4) • The data from all fingers are algorithmically combined to create a multifunctional biocode. • Access is only granted if the correct combination is recognized. • In case of injury, the system automatically suggests registered replacement fingers. Safety advantages • Copy protection: A single finger is not enough – even with perfect imitation • Fault tolerance: Alternative fingers can be used • Dynamic combinations depending on the application context 9. Application examples • Banks: Access to account or safe only via combined fingerprint verification • Police: Registration for duty, activation of equipment, real-time status updates • Museums: Access to valuable exhibits only through combined verification • Vehicles: Start release only with correct finger combination • Events: Entry control via multifunctional biocode - no tickets required • Research laboratories: Activation of high-risk equipment only through collective authorization • Military systems: Access to strategic data only through multi-person authorization Image Description Fig. The image shows a cross-sectional view of the cylindrical biometric identification lock. The lower section contains a structured sensor glass surface for capturing fingerprints and subarticular tissue characteristics. The upper section contains integrated laser sensors for measuring finger thickness, skin folds, and for generating a laser-based biological line along the finger axis. The finger is inserted centrally and captured segmentally. Fig. 2 Legend 1 case 2 Sensor glass surface 3 Biometric sensor blocks 4 laser sensor blocks 5 sensor carriers
