Problems solved by technology

[0003] In the two-dimensional codes described in Patent Documents 1 and 2, there is a lack of decoration, and images cannot be placed in the two-dimensional codes
The technical QR code described in patent document 3 can superimpose any picture, but due to the limitation of harmony, it cannot represent a clear image
[0004] According to the technology in Non-Patent Document 1, the member information in the portable terminal device can be collected; however, the portable terminal device may be used by others, and there are problems in information security

Embodiment 1

[0069] figure 1 It is a schematic diagram of the overall composition of the system in an embodiment related to the present invention. This system includes the following devices: a portable terminal 101 held by the user, a management server 102 for user login management or point management, and an in-store PC (personal computer) 103 for accepting point coupons. The portable terminal 101 and the management server 102 can be connected through media such as the network provider of the portable terminal or the Internet, and the management server 102 and the in-store PC 103 can be connected through a dedicated line or a medium such as the Internet.

[0070] The user connects to the management server 102 via the portable terminal 101, and downloads a specified application program from the management server 102 to the portable terminal and installs it. The application installation processing unit 121 of the management server 102 executes the installation process of the program. The ...

Embodiment 2

[0120] The present invention discloses an encryption system of the above-mentioned two-dimensional code. The encryption system includes a user terminal device, a client computer, and a management server; the user terminal device, the client computer, and the management server are connected.

[0121]The user terminal device is used to represent the user's number ID through the first region of the two-dimensional code, and represent the user's password or setting data through the second region of the two-dimensional code.

[0122] The client computer receives the two-dimensional code sent by the user terminal device, decodes the ID and password or setting data corresponding to the two-dimensional code, and sends the decoded ID and password or setting data to the management server; and receives The verification result sent by the management server.

[0123] The management server stores the ID, password or setting data of each user through the user database; receives the ID, passw...

Embodiment 3

[0132] An encryption system of a two-dimensional code, the encryption system includes a user terminal device, a client computer, and a management server; the user terminal device, the client computer, and the management server are connected;

[0133] The user terminal device is used to represent the user's number ID through the first region of the two-dimensional code, and represent the user's password or setting data through the second region of the two-dimensional code;

[0134] The client computer receives the two-dimensional code sent by the user terminal device, and sends the obtained two-dimensional code to the management server; and receives the inspection result sent by the management server;

[0135] The management server stores the ID, password or setting data of each user through the user database; receives the two-dimensional code sent by the client computer, decodes the corresponding ID and password or setting data of the two-dimensional code; and checks the receiv...

Abstract

The invention discloses a two-dimensional code, a coding system and method of the two-dimensional code. The coding method includes the steps of, a user's terminal device representing a user's ID through a first region of the two-dimensional code, and representing a user's cipher through a second region of the two-dimensional code; a client computer receiving the two-dimensional code sent from the user's terminal device, decoding ID and cipher corresponding to the two-dimensional code, and sending the decoded ID and cipher to a management server; the management server examining the consistency of the ID and cipher and the data stored in a database, and sending the examining results to the client computer; and the client computer receives the examination result sent from the management server. User's ID and cipher can be set in a two-dimensional code, which improving safety. A two-dimensional code with a simple structure can represent encryption of a given user's ID, checks ID cipher logged on a server, thereby ensuring user's information safety.

Description

technical field [0001] The invention belongs to the technical field of two-dimensional code encryption, and relates to a two-dimensional code, in particular to an encryption system of a two-dimensional code, and to an encryption method of the above-mentioned two-dimensional code encryption system. Background technique [0002] Historically, there have been many QR codes that hold data. For example: the QR code in patent document 1 (save the trademark) and the two-dimensional code in the patent document 2 that stores data by color and the shade of the color, etc. In addition, there are two-dimensional codes that store data through images like in Patent Document 3, and two-dimensional codes that store customer-specific membership cards in Non-Patent Document 1. [0003] The two-dimensional codes described in Patent Documents 1 and 2 lack decorativeness, and images cannot be placed in the two-dimensional codes. The technical QR code described in patent document 3 can superimp...
