[0048] On the other hand, an embodiment of the present invention provides an intelligent blood pressure monitor system, which includes any of the above-mentioned intelligent blood pressure monitors.

[0049] In an optional embodiment, a readable storage medium is further included, on which the following user identification method is stored: obtaining user registration characteristics; when the user measures blood pressure, identifying the user identity based on the user registration characteristics.

[0050] In an optional embodiment, obtaining user registration characteristics includes the following steps:

[0051] Step A: Modeling the cuff's pressure topology. This step involves embedding a flexible piezoresistive sensor array (e.g., a 64-point matrix) within the cuff's inner layer. The sensor automatically records the spatiotemporal distribution of pressure points during inflation when the user first wears the cuff. A three-dimensional pressure cloud model is then constructed to extract the following pressure topology features: a) circumferential pressure gradient distribution curve for the forearm, b) axial pressure decay rate characteristics, and c) a dynamic response spectrum of muscle elastic recoil force.

[0052] Step B, extracting pulse wave biometrics, includes synchronously acquiring a high-precision pulse wave signal (sampling rate may be 1 kHz) for a preset time (e.g., 30 seconds) during a standard blood pressure measurement. Using wavelet transform, the following are extracted: a) the main wave-to-tidal wave amplitude ratio (A1 / A2); b) the reflected wave delay characteristic (Δt); and c) a personalized waveform complexity index (calculated using the Lempel-Ziv algorithm).

[0053] Step C, feature fusion encryption and storage step, which includes: cascading the pressure topology features and the pulse wave features, using the improved Triplet loss function to train the twin neural network, generating a 128-dimensional biometric feature vector, encrypting it with the national secret SM4 algorithm and storing it in a security chip to obtain the user registration features in the embodiment of the present invention.

[0054] Step D, dynamic identity authentication step: when the user measures blood pressure, the user's identity is identified based on the user's registration features.

[0055] This step includes: an instant pre-identification step upon wearing. Furthermore, when the cuff wearing action is detected, the initial pressure distribution data (e.g., the first 3 seconds of the uninflated state) is collected in real time. An improved DTW algorithm is used to quickly match the data with the registered features, and the top N candidate users with the highest similarity (N≤3) are selected.

[0056] Dynamic verification steps of the inflation process: During the blood pressure measurement inflation phase (e.g., 20-30 seconds): record the dynamic response curve of the pressure sensor array every 5ms; synchronously extract the rising edge features of the pulse wave; and calculate the feature similarity with the candidate user in real time through the attention mechanism LSTM network.

[0057] Adaptive decision fusion steps: A decision-level fusion algorithm based on DS evidence theory is adopted: pressure topology matching (weight 0.6), pulse wave time domain feature similarity (weight 0.3), usage habit auxiliary features (such as common time periods, measurement intervals) (weight 0.1), and identity authentication is completed when the comprehensive confidence level is >85%, otherwise the security enhancement mode is activated.

[0058] The embodiment of the present invention adopts a multimodal feature collaborative recognition step: creatively combining the dual biomarkers of pressure distribution (anatomical feature) and pulse waveform (physiological feature), which improves the recognition accuracy by 37.2% (simulation test data) compared with a single biometric feature.

[0059] Dynamic process feature extraction step: Breaking through the limitations of traditional static biometrics, the unique inflation process of the blood pressure monitor is used to dynamically collect feature data, making it impossible for attackers to cheat through static copying.

[0060] Embedded optimization algorithm: Design a lightweight neural network model (parameter size <50KB) that can run in real time on the ARM Cortex-M4 core, reducing power consumption by 68% while maintaining 98.6% recognition accuracy.

[0061] This embodiment of the present invention fully utilizes the inherent sensors of a blood pressure monitor to achieve user identification without additional hardware. Its unique dynamic biometric fusion mechanism significantly improves identification reliability. Compared to traditional solutions (such as external fingerprint modules), it offers significant advantages in terms of cost, power consumption, and user experience.
