The invention relates to a safety protection method for a mobile terminal, a mobile terminal, a safety
system and an application method. The safety protection method is used for increasing the safety of the mobile terminal and is easy in operation. According to the safety protection method for the mobile terminal, a separate area is isolated on the mobile terminal and taken as a safety area, a
third party application outside the safety area cannot access the application and data in the safety area, and a user is required to pass the safety
verification in order to enter into the safety area. The safety
system is characterized in that a cloud safety management platform is mainly used for performing mutual collaborative
interlocking between the safety area of the mobile terminal, the
system kernel of the mobile terminal and the cloud safety management platform, so that the running of the safety area under a safe and reliable environment is ensured, and the safety area is safe. A trust chain is built in the safety area, an application method for realizing the running
access management for the application and data on the basis of the trust chain is adopted, and the biometric features recognition is taken as the
verification for entering into the safety area, so that the safety is further promoted.
