A method of detecting threshold voltage shift and a threshold voltage shift detection device are provided. The method is applied to a pixel driving circuit which I is electrically coupled to a control line, a voltage line and a detection node, respectively. The method includes: in a detection cycle including a setting phase and a detection phase, in the setting phase, controlling a transistor included in the pixel driving circuit to be in a biased state; in the detection phase, providing a preset control voltage signal to the control line, providing a preset voltage signal to the voltage line, and determining a threshold voltage shift state of the transistor according to an electric potential of the detection node.

An access permission level for a first individual may be calculated by utilizing repositories of social network databases. The facial image of a first individual may be captured and compared with a repository of pre-categorized individuals. In response to the facial image of the first individual being absent from the repository of pre-categorized individuals, the repositories of social network databases may be crawled to collect facial images of non-categorized individuals. The first facial image may be compared with the facial images of non-categorized individuals, and a second individual may be identified. In response to identifying, categorization data associated with the second individual may be collected. Utilizing the categorization data, the second individual may be sorted into one of a plurality of categories. Based upon an image match score and the category which the second individual is sorted into, an access permission level may be determined and provided to a user.
