Embodiment Construction
[0041] figure 1 is a conventional segmented display screen that can be divided into twenty-eight segments. Segment code display Common calculator display is a typical segment code display.
[0042] figure 2 Based on the basic structure of this dynamic token, image 3 In order to increase the dynamic token of the photoelectric sensor 5, the photoelectric sensor is the photoresistor and other equipment.
[0043] Such as figure 1 , 2 , a kind of dynamic token based on segment code display, it is characterized in that this dynamic token comprises a segment code display 2, single-chip microcomputer 3 and power supply 4, also has a wake-up button 1, presets identity code in the program of described single-chip microcomputer 3 and use count value, or single-chip microcomputer 3 is provided with external memory to store preset identity code and use count value; Wherein said identity code is factory setting code, and each dynamic token is all different, and this identity code is us...

The invention relates to a dynamic token based on a segment code display and a method and application thereof. The dynamic token comprises the segment code display, a singlechip, a power supply and awake-up button. The wake-up button is pressed down, a use count value is added with 1, and the singlechip generates a binary character string by an identity code of the singlechip, the use count valueand a pseudo random number; and one part of digits in the character string are enabled to correspond to one part of segment codes in the segment code display, and when values of digits in the one part of digits are 1, the segment codes corresponding to the digits are lighted up so as to form a pattern on the segment code display, which can be used for fire prevention routing inspection. Accordingto the invention, a special routing inspection rod device is not required, and routing inspection can be implemented only by using a mobile phone with a shooting function; automatic identification and verification of a computer algorithm can be implemented, and the dynamic token has an excellent anti-counterfeiting function; hardware cost of the device is obviously reduced; and the dynamic tokenadopts abstract symbols which are not universal and are unsuitable for human eyes to read, and is beneficial to information secrecy.
Description
technical field [0001] The invention relates to a dynamic token, in particular to a dynamic token based on a segment code display and a method thereof. Background technique [0002] A dynamic token is an electronic device that stores and displays a password. Its main purpose is to display a password for a specific purpose when the user needs it. [0003] The form of the password is not limited to symbols such as numbers, letters, and text that can be recognized by the human eye, but also abstract graphics such as two-dimensional codes. [0004] With the popularization and wide application of two-dimensional codes, the number of ciphers used to display two-dimensional codes is gradually increasing. In the prior art, an electronic device with a dot matrix display is usually used to display password information in the form of two-dimensional codes. The disadvantages of this device are: 1) the cost of the dot matrix display is relatively high; 2) the power consumption of the do...
