<p>The present invention relates to an OTP device and method integrating photographing and bar code identification technology, belonging to the technical field of network information security authentication. The OTP device of the present invention comprises a CPU processing module, a photographing module, a display module, a key module, and a power supply management module supplying power for the above modules; the photographing module, the display module and the key module are connected to the CPU processing module; the photographing module is used to photograph a bar code image and transmit the photographed bar code image to the CPU processing module; and the CPU processing module is used to parse the bar code image, transmit transaction information data to the display module for display, correspondingly process the response of a key, and generate an answer-back code by means of seed key calculation and a built-in algorithm. The device and method of the present invention improve OTP universality, thus enabling the OTP to be used not only on a PC, but also on a mobile intelligent device such as a mobile phone, a netbook, and a tablet computer.</p> |
