  • Publication number: 20170169350
    Abstract: A method for measuring user behavior consistency degree based on a complex correspondence system, which is applied to internet payment platform security. An entire solution is divided into three stages: at a first stage, analyzing complex correspondence relation characteristics according to an existing user behavior model; at a second stage, establishing a behavior profile according to user behavior characteristics and establishing user behavior relation matrixes; and at a third stage, completing user behavior matrix decomposition according to the complex correspondence characteristics of a user, calculating a user behavior consistency degree and detecting a degree of consistency between user behaviors and expected behaviors.

  • Publication number: 20160216102
    Abstract: The present invention provides a detection device and a detection method. The detection device comprises a light source module, a receiving module, an image generation module and a judgment module, wherein the light source module is configured to emit light towards a film at a predetermined angle, the receiving module is configured to receive interference light formed by first reflected light reflected by an upper surface of the film and second reflected light reflected by a lower surface of the film, the image generation module is configured to generate an interference fringe image according to the interference light, and the judgment module is configured to judge whether thickness of the film is uniform according to the interference fringe image. The detection device can perform high accuracy detection on uniformity of the thickness of a film, thereby facilitating improving display quality of a display panel.

  • Publication number: 20140002462
    Abstract: The present disclosure relates to the field of communications technologies, and in particular, to a method and a mobile terminal for dynamic display of an emotion. In the method, the mobile terminal obtains a trigger event, where the trigger event is used to trigger dynamic display of an emotion. The mobile terminal searches an emotion package of the emotion according to the trigger event and obtains an animation instruction of the emotion, where the emotion package of the emotion includes a media material file of the emotion. The mobile terminal utilizes an animation capacity of the mobile terminal, and operates according to the animation instruction of the emotion, the media material file of the emotion, so as to implement the dynamic display of the emotion.
