[0049] In an optional embodiment, the system further includes a readable storage medium storing the following user identification method: acquiring user registration features; and identifying the user's identity based on the user registration features when the user measures their blood pressure.

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

[0051] Step A: Cuff pressure topology modeling. This step includes embedding a flexible piezoresistive sensor array (such as a 64-point matrix) into the inner layer of the cuff. When the user wears the cuff for the first time, the spatiotemporal distribution data of each pressure point during inflation is automatically recorded. A three-dimensional pressure cloud model is established, and pressure topology features are extracted: a) the circumferential pressure gradient distribution curve of the forearm, b) the axial pressure decay rate characteristics, and c) the dynamic response spectrum of muscle elastic recoil force.

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

[0053] Step C, Feature Fusion Encryption and Storage Step, includes: cascading and fusing pressure topology features and pulse wave features, training a Siamese neural network using an improved Triplet loss function, generating a 128-dimensional biometric vector, encrypting it using the national cryptographic SM4 algorithm, and storing it in a secure chip to obtain the user registration features in this embodiment of the invention.

[0054] Step D, Dynamic Identity Authentication Step: When a user measures their blood pressure, the user's identity is identified based on the user's registration characteristics.

[0055] This step includes an immediate pre-identification step upon wearing the cuff. Further, when the cuff-wearing action is detected, initial pressure distribution data (e.g., the first 3 seconds before inflation) is collected in real time and quickly matched with registered features using an improved DTW algorithm to filter out the top N candidate users (N≤3) based on similarity.

[0056] Dynamic verification steps during inflation: During the inflation phase of blood pressure measurement (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; calculate the feature similarity with the candidate user in real time through an attention mechanism LSTM network.

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

[0058] The embodiments of the present invention employ a multimodal feature collaborative recognition step: creatively combining pressure distribution (anatomical features) and pulse wave waveform (physiological features) as dual biomarkers, which improves the recognition accuracy by 37.2% compared to single biomarker recognition (simulation test data).

[0059] Dynamic process feature extraction steps: Breaking through the limitations of traditional static biometrics, it utilizes the unique inflation process of the blood pressure monitor to dynamically collect feature data, making it impossible for attackers to deceive through static replication.

[0060] Embedded optimization algorithm: Design a lightweight neural network model (parameters <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 invention fully utilizes the inherent sensor of the blood pressure monitor to achieve user identification without any additional hardware, and significantly improves identification reliability through a unique dynamic biometric fusion mechanism. Compared with traditional solutions (such as external fingerprint modules), it has significant advantages in terms of cost, power consumption, and user experience.

[0062] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
