Abstract: Disclosed are an emergency call-for-help method and system based on fingerprint identification for a mobile terminal, and a mobile terminal. When a user is in an emergency, a mobile terminal sends an emergency short message including positional information to emergency contacts, and automatically calls the numbers of all the emergency contacts, so as to rapidly send a call-for-help signal to the outside world, thereby guaranteeing the user's safety, reducing safety risks and being convenient for the user.

Abstract: A fingerprint recognition and NFC-based unlocking method using a mobile terminal includes: when the mobile terminal approaches an intelligent lock, establishing, by the mobile terminal, a data communication connection to the intelligent lock by means of NFC; sending, by the intelligent lock by means of NFC, an fingerprint authentication instruction to the mobile terminal, and after receiving the instruction from the intelligent lock, displaying, by the mobile terminal, a fingerprint authentication interface on a screen and after receiving a fingerprint input by a user, sending, by the mobile terminal, the fingerprint to the intelligent lock, and comparing, by the intelligent lock, fingerprint information with fingerprint data in a database, where after recognition succeeds, the intelligent lock is unlocked. A fingerprint recognition and NFC-based unlocking system using a mobile terminal is also disclosed.
