Abstract: A terminal device first authenticates whether the terminal device has permission to sense a to-be-measured object. If the terminal device has sensing permission, the terminal device senses the to-be-measured object. If the terminal device has no sensing permission, the terminal device does not sense the to-be-measured object. In this way, privacy leakage of the to-be-measured object is prevented.
