    Abstract: An electronic device receives a first input, where an air pump inflates and pressurizes an airbag. The electronic device obtains a pressure value of the airbag in a process of controlling the air pump to inflate and pressurize the airbag. The electronic device obtains a first pressure signal, where the first pressure signal is a signal indicating that the pressure value of the airbag changes with time in a process in which the air pump starts to inflate and pressurize the airbag until the pressure value of the airbag is equal to a preset pressure value. The electronic device determines, based on the first pressure signal, tightness of wearing a wristband by a user. The electronic device corrects, based on the tightness, a blood pressure measurement value determined based on a second pressure signal, to determine a blood pressure value of the user.

    Abstract: A data processing method includes obtaining positioning data collected during positioning, obtaining a fingerprint set from a location database based on the positioning data, where the fingerprint set includes at least one fingerprint, and each fingerprint in the fingerprint set includes at least one positioning media access control (MAC) address, determining, for each fingerprint in the fingerprint set, a matching degree between the fingerprint and the positioning data based on a second signal strength and a first signal strength of each positioning MAC address in the fingerprint, and determining that an access point (AP) included in the positioning data moves when each of matching degrees of all fingerprints in the fingerprint set is less than a first threshold.
