Embodiment 1

[0019] The current ticket is the ticket corresponding to the train at 10:00 am on January 1, 2020, and the time period for entering the waiting room is from 8:00 am to 10:00 am on the next day. The current time is 11 am on October 1, 2019, and the identification code of the note holder is 101. refer to figure 1 , follow the steps below to generate a serial number, password and dynamic code for the current ticket:

[0020] Step 101, generate a unique serial number for the current bill as a plain code, and the serial number is 10001.

[0021] Step 102, obtain the identification code of the note holder, add the identification code of the note holder and the serial number to obtain 10102 and convert it into a string, and then append the current time in the format of year, month, day, hour and minute to the end of the string , the resulting string is "10102201910011100".

[0022] In step 201, the character string obtained in step 102 is used to generate a password through the A...

Embodiment 2

[0027] The difference between this embodiment and Embodiment 1 is that the ticket holder has no identification code.

[0028] The difference between step 102 and embodiment 1 is that a unique identification code 102 is generated for the note holder. Add the identification code of the note holder and the serial number to get 10103 and convert it into a string, and then append the current time in the format of year, month, day, hour, and minute to the end of the string. The final string is "10103201910011100".

[0029] The difference between step 501 and embodiment 1 is that the serial code and the secret code in the form of barcode are printed on the bill and handed over to the bill holder, and the Chinese character "two" of the dynamic code corresponding to the valid time period is sent to the mobile phone text message, email or The form of pushing in the software is handed over to the ticket holder.

[0030] Other steps in this embodiment are the same as in Embodiment 1.

Abstract

The invention relates to the field of information security, and provides a bill dynamic code generation method based on time limitation. A server generates a serial number serving as a plain code, a secret code obtained through an ASC encryption algorithm and dynamic codes corresponding to different time periods for a formulated bill. Wherein the time periods comprise a plurality of invalid time periods and valid time periods, and only the dynamic codes of the valid time periods are given to the bill holder. The bill dynamic code generation method solves the problems that a dynamic password using cipherer is high in cost, and the generation process is not safe, and the dynamic password checking process is not suitable for manual operation.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method for generating dynamic codes of bills based on time limitation. Background technique [0002] As a transaction certificate, bills are widely used in various industries. Generating specific serial numbers and passwords for bills is a common technical means to verify the authenticity and effectiveness of bills. Nowadays, many places need to verify tickets to enter, such as large-scale concerts, sports competitions, large-scale evening parties, banquets, etc. Tickets also play an important role in the transportation industry such as trains, airplanes, ships and other passenger services. In these scenarios, the authenticity, validity and timeliness of bills are particularly important. Compared with the cooperation of the traditional solid-state serial number and password, the prior art has developed a technical solution using a dynamic password to ensure that the timelin...
