Abstract: The present disclosure relates to blood pressure calibration period determining methods and devices. One example method includes obtaining, by a blood pressure measurement device, first physiological status information and second physiological status information of a tested person, where the first physiological status information is related information that causes a change in blood pressure of the tested person within a first time period after the blood pressure is calibrated, and where the second physiological status information is related information that causes a change in the blood pressure of the tested person within a second time period before the blood pressure is calibrated, and determining, by the blood pressure measurement device, a blood pressure calibration period based on a degree of change of the first physiological status information relative to the second physiological status information.

Abstract: A blood pressure monitoring method, apparatus, and device are provided. The method includes: collecting a first biological signal of a to-be-measured user (S101); and predicting a first blood pressure value of the to-be-measured user based on the first biological signal and a pre-established individual calibration model (102). According to the method, only the first biological signal of the to-be-measured user needs to be collected to predict the first blood pressure value of the to-be-measured user. A collection manner is simple, and sleep of the user is not interrupted, greatly improving user experience.

Abstract: The present disclosure relates to an identity authentication method and a communications terminal. One example method includes: performing, by a terminal, first identity authentication on first user identity feature data; if the first identity authentication succeeds, and the wearable device is in a valid worn state, when receiving an access request for a preset application, obtaining, by the terminal, a service security level of the preset application, and obtaining an authentication time point for second identity authentication and matching accuracy of the second identity authentication; determining whether a difference between a current time point and the authentication time point is less than authentication validity duration corresponding to the service security level and whether the matching accuracy is higher than lowest matching accuracy corresponding to the service security level; and if yes, accepting the access request.
