I. System Architecture
ThinkRace, based on the mature hardware platform of electronic ankle bracelets and smart wristbands, has officially launched the revolutionary security module – Aurora Chrono Seal AI. This module consists of a single-mode optical fiber circuit embedded in the strap, a multi-wavelength LED transmitter, a spectral sensing receiver, and an edge AI inference chip. It integrates physical tamper-proofing and AI encryption verification, setting a new security benchmark for global judicial supervision.
II. Aurora Chrono Seal AIEncryption Mechanism
The system adopts dual-factor optical cryptography:
• Wavelength Factor (Color Key): The transmitter injects light pulses of a specific wavelength into the optical fiber, and the receiver detects the wavelength characteristics through a spectral decomposer. Any replacement of the strap material or fiber breakage will cause wavelength drift or attenuation, triggering tampering alerts.
• Time Sequence Factor (Chrono Key): The AI chip controls the transmitter to modulate the width and interval of the light pulse with millisecond-level precision, forming a dynamic time sequence password. This time sequence is generated by the edge AI based on the wearing time and environmental light noise, possessing one-time password (OTP) characteristics to prevent replay attacks.
The dual factors are fused through an XOR logic gate at the hardware level to generate a unique device binding signature. Only when the spectral characteristics and the time sequence sequence simultaneously pass the LSTM time series prediction network of the AI model are verified, will the MCU send a “STRAP_INTACT” high-level signal to the main system.
III. Anti-Tampering Response Link
The anti-tampering logic of this design is extremely rigorous. Any attempt to cut, replace, or forge the strap will result in a disruption of the light signal or a change in the characteristics. The AI chip identifies anomalies within microseconds and triggers an immediate alarm and synchronously uploads to the cloud supervision platform. Compared to the mechanical anti-pull sensors relied on by traditional electronic ankle bracelets, Aurora Chrono Seal AI has achieved a leapfrog upgrade from “physical detection” to “optical encryption verification”, completely eliminating the possibility of “counterfeit straps”.
在硬件层面，Thinkrace的智能穿戴设备已具备IP68防水防尘、多模定位（GPS/GLONASS/Wi-Fi/LBS）、4G实时通信、TLS加密传输以及双加密算法（ChaCha20-Poly1305和AES）等成熟能力。Aurora Chrono Seal AI作为额外的安全层，与电子围栏、实时追踪、历史轨迹回放和运动分析等现有功能无缝集成，形成“定位-监控-加密-防篡改”的闭环监管系统。
From pre-trial monitoring, community correction, home detention to bail supervision, ThinkRace uses the Aurora Chrono Seal AI to secure judicial safety.
