Description

Introduction:

[0001] The invention relates to an electronic lock with AI-supported access verification that operates via magnetic coupling and is self-charging. The system is based on a two-part design, utilizes multiple energy sources, and allows offline communication with a biometric radio key. It also includes modular components and mesh communication for crisis and emergency use. Applicant:

[0002] Ewa Musiol Kampenwandstr. 3 83059 Kolbermoor Germany Technical field:

[0003] The invention relates to an electronic lock with integrated artificial intelligence (AI) designed for secure access to rooms, vehicles, or facilities. The lock operates independently of external cloud services and is triggered by an authorized radio key, which is described in a separate, already patented intellectual property right (DE102021125075B3). State of the art:

[0004] Familiar smart locks rely on cloud-based systems with basic Bluetooth communication and often require a constant power supply or battery replacement. In contrast, the present system offers a runtime of up to several years through magnetic self-charging, optionally supplemented by solar power. While conventional locks like Nuki or Yale use standard Bluetooth protocols with limited range and security (AES-128), the ALPHAKEY X system employs highly secure, locally encrypted connections (e.g., UWB or AES-256), completely independent of third-party clouds. Security vulnerabilities exist due to third-party clouds, limited biometric systems, and a lack of offline functionality. A scalable, fully autonomous solution that combines power supply, AI security, and remote connectivity with a biometric key is not currently known. Why is this system better than existing solutions?

[0005] In contrast to existing systems (e.g., Nuki, Yale, Danalock) which are limited to battery-powered, cloud-based Bluetooth connections, the present invention offers a fully self-sufficient, AI-driven security architecture with multiple power supplies and locally anchored access verification. Technical differences include: battery life of up to 5 years, AES-256 or post-quantum encryption, self-diagnostics, offline AI, and mesh redundancy. Why is it sustainable and inclusive?

[0006] Thanks to the use of maintenance-free supercapacitors, recyclable materials (aluminum, glass, ceramic), solar backup, and NFC power supply, the system can be used in a CO2-neutral manner in the long term. Multilingual offline voice control, haptic feedback, and gesture control enable barrier-free and inclusive use, even for people with sensory impairments. Supported gestures include: raising the hand, waving, double-tapping in the air, and circular movements in front of the panel. Why is it so versatile in terms of patent law?

[0007] The invention has a modular structure and covers both the overall system and individual key modules such as power supply, communication, gesture control, or AI behavior analysis. These can each be licensed or protected separately. This creates a flexible patent network with a high degree of strategic protection against imitators. Data protection and GDPR compliance:

[0008] By processing all biometric and security-relevant data on-site, the system inherently complies with the principles of data protection and privacy by design according to the GDPR, in particular Article 25. Security logs are stored locally and automatically deleted on a regular basis to ensure long-term GDPR compliance. Communication with external cloud servers is not required. Other strengths:

[0009] The ALPHAKEY X system harvests energy through magnetic coupling every time a door is closed, making it particularly suitable for critical infrastructure, emergency scenarios, and operation during blackouts. This self-sufficient energy storage ensures the lock remains functional even during extended periods without power. It combines magnetic induction, kinetic energy recovery, solar cells, and NFC harvesting in an adaptive energy management system. Advanced Features:

[0010] Additionally integrated are a Matter-compatible smart home connection (without cloud requirement), local blockchain logging of accesses, environmental sensors (e.g., CO2, smoke, temperature, motion), an upgrade interface (USB / NFC), automatic error logging, QR update scan, and wearable authentication options such as NFC rings or biometric wristbands. Data encryption can optionally be based on post-quantum resistant algorithms. Suitability for NEOM and global crisis deployments:

[0011] The system was specifically designed for state-of-the-art, networked environments such as smart cities (e.g., NEOM), remote regions, developing countries, military installations, and civil disaster relief solutions. All security-relevant functions are fully usable offline, ensuring that ALPHAKEY X continues to operate reliably even in the event of power or internet outages. Licensing potential:

[0012] The modular architecture allows for the licensing of individual system components (e.g., energy unit, communication module, panel control, AI analysis block), which significantly increases economic viability and strategic protection scope. AI control:

[0013] The AI ​​component is based on a locally implemented, adaptively learning model (e.g., decision tree or neural network). The architecture allows for the future local operation of more advanced models such as LLMs (Large Language Models) or transformer-based micro-AIs, provided this is supported by the hardware. Data protection and GDPR compliance:

[0014] Furthermore, the AI ​​module is designed to be adaptable to current and future regulatory requirements (e.g., EU AI Regulation, BSI IT Baseline Protection, GDPR Art. 22). In particular, a classifiable risk analysis of the AI ​​logic is provided to ensure the system can be operated legally even in security-critical environments. Advanced Features:

[0015] The access control logic can be dynamically adapted based on local environmental sensors. For example, access can be automatically denied in the event of smoke, critical CO2 levels, or elevated temperatures to prevent endangering the people involved. Purpose of the invention:

[0016] The aim of the invention is to provide a fully autonomous, secure and maintenance-free lock that is particularly suitable for use in power- and grid-independent environments and meets the highest requirements for data protection, energy self-sufficiency, accessibility and intelligent security logic. The invention is intended to fulfill the following tasks in particular: ◯ Provision of an electronic lock module with a self-charging power supply based on magnetic induction, which also absorbs energy in standby mode (e.g. when the door is closed) via a coupled charging device in the door frame. ◯ Integration of a modular system architecture with separately replaceable and licensable components (e.g., power unit, communication module, sensors, panel, AI unit). ◯ Combination of multiple energy sources for redundant power supply, including magnetic coupling, kinetic energy (e.g., from door movement), NFC harvesting, and optional microsolar cells in the door frame. ◯ Use of maintenance-free nano supercapacitors with extremely high charge cycle stability and fast charging capability (>100,000 cycles). ◯ Local, cloud-free processing of biometric data (e.g., face, fingerprint, voice, behavior) to ensure full GDPR compliance and data protection according to the principle of "Privacy by Design". ◯ Implementation of a learning-capable, AI-supported behavioral analysis, which uses, for example, time of day, gait patterns, usage frequency and emotional tone of voice for anomaly detection. ◯ Option for offline-capable, encrypted remote verification using a biometrically authorized radio key. ◯ Implementation of an optional gesture-based control for barrier-free use (e.g. hand signals, circular movements), supplemented by multilingual offline voice control and haptic feedback. ◯ Offline connectivity via a mesh communication network that can relay status messages, emergency commands or alarms between multiple locks even in the event of a power outage or internet interruption. ◯ Integration of a panic mode and covert emergency protocol that triggers a silent alarm in threat scenarios (e.g. coercion, assault) without altering the external process. ◯ Ensuring emergency functionality in crisis situations: The system detects network or power outages and activates a self-sufficient crisis mode with restricted but secure access. ◯ Ensuring future-proofness through USB / NFC-based update interfaces and self-healing software processes (e.g., auto-diagnosis, reboot, QR error log). ◯ Deployment in smart cities, energy infrastructure, care facilities, developing countries, vehicles, containers and high-security environments such as the Saudi NEOM or UN projects.
