1. An integrated control chip for driving a display device, comprising:

  • a display unit for providing a display driving signal to a display device;

    a sensor unit for receiving a sensing signal from a biometric sensor and converting the sensing signal into biometric data;

    a processor, which is used for controlling the display unit and the sensor unit, and is used for extracting biological characteristics from biological characteristic data from the sensor unit to form a biological characteristic template when receiving a biological characteristic registration request, binding the biological characteristic template with a random secret key through a fuzzy algorithm to obtain an encrypted biological characteristic template, and outputting the encrypted biological characteristic template when receiving a template acquisition request; and

    a storage unit for locally storing the encrypted biometric template in the integrated control chip after the encrypted biometric template is obtained,wherein the sensor unit has a sensor interface to receive biometric data and the display unit has a display to receive display data and a graphical interface.
