The present application embeds high-sensitivity
quantum gravimeter in large equipment which needs to verify identity, measures the gravity characteristics of the environment where the equipment is located in real time, and compiles the gravity characteristics into a complex gravity characteristic
signal; when the identity
authentication of the equipment in other places is initiated, the gravity characteristic
signal needs to be uploaded in addition to the input
password, and the
network administrator or identity
authentication verifier needs to compare and verify the uploaded gravity characteristic
signal by referring to the existing gravity field
database in addition to verifying the
password, so as to approve the real location of the equipment in other places which initiates the identity
authentication, and prevent the equipment which steals the
password and is in an unexpected location from impersonating identity to access a network with
high security requirements or obtain information with
high security level. The physical means provided by the present application is an important supplement to the existing
information science means and biological means, and provides a new method with stronger reliability for identity authentication in other places, and greatly improves the management and control ability of the communication network to the access equipment.
