Abstract: Apparatus and methods for enhancing security of an authentication process of a caller that initiated a call in an Interactive Voice Response (“IVR”) system are provided. The methods may include routing the call through the IVR system to a headset. After the routing, the methods may include retrieving data associated with the caller. In response to the retrieved data meeting one or more predetermined conditions, a graphical user interface of an agent computer paired to the headset may display a plurality of validation information for validating the caller. Selection by the agent of validation information may trigger methods for transmitting a request to the caller, via a caller mobile phone, to input the validation information selected by the agent. The methods may additionally include authenticating the caller based at least in part on the information input into the mobile phone.

Abstract: A liquid crystal display device and a control method thereof are provided. The liquid crystal display device includes a liquid crystal display unit, a position capturing unit, a control unit and at least two backlight units. The at least two backlight units have different light emergent directions; the position capturing unit is configured to collect position information of a user, and feed the position information back to the control unit; the control unit is configured to acquire a viewing angle of the user based on the position information, and control the backlight unit having a light emergent direction matching with the viewing angle to emit light, and meanwhile, adjust a brightness of the liquid crystal display unit, so as to make the brightness match with the viewing angle. The liquid crystal display device can ensure no loss of image quality in a liquid crystal display device at different viewing angles.
