    Abstract: Embodiments of the present disclosure provide a fingerprint identification module, a fingerprint identification method and a display device. The fingerprint identification module includes: a capacitive sensor having a plurality of capacitive electrodes which do not contact with each other, the capacitive sensor being configured to identify a fingerprint of a finger based on induced capacitances generated between the capacitive electrodes and ridges in an epidermal layer of the finger and generated between the capacitive electrodes and valleys in the epidermal layer; a radio-frequency sensor having a plurality of radio-frequency receiving electrodes which do not contact with each other, the radio-frequency sensor being configured to identify the fingerprint based on reflected signals received by the radio-frequency receiving electrodes; and a controller configured to activate the radio-frequency sensor to identify the fingerprint when fingerprint information identified by the capacitive sensor is not consistent with fingerprint information pre-stored in the fingerprint identification module.

    Abstract: The present disclosure provides a securing method and securing apparatus for an application, as well as an electronic device. The method comprises the steps of: after receiving a touch-sensitive instruction triggered by a user for opening a first application, displaying a first display frame for prompting the user to input a fingerprint key in an electronic device interface; receiving the fingerprint key input through the first display frame by the user; comparing the received fingerprint key with a preset encryption fingerprint key to obtain a matching result, the encryption fingerprint key being a key preset by the user for protecting the first application; and determining whether or not to open the first application according to the matching result. The method is capable of setting different encryption fingerprint keys for individual applications of the electronic device, so as to better protect the user information and improve user experiences.
