Abstract

A mobile device comprises a pupil information collecting module and a master control module, such that the pupil information collecting module may be used for collecting pupil characteristic information of a user. The master control module may receive the pupil characteristic information of the user when the user accesses a controlled unit, and may determine, on the basis of the pupil characteristic in formation of the user, if the user is allowed to access the controlled unit. The mobile device may use the pupil characteristic information of the user to perform identity verification.

First claim
