Description

Method for data exchange using two-dimensional barcode

The present invention relates to data exchange, and more particularly to a method of exchanging data using a two-dimensional barcode.

Data transmission has been widely used in modern people's lives, especially wireless data transmission methods, which can greatly improve the user's use of wired transmission, which is plagued by wire entanglement and carrying transmission wires.

However, in the general case of smart phones, the use of smart phones for data transmission is quite common. However, if the data is not changed in any way, such as the transmission of image data, if the transfer format is not converted, It is easy for other people nearby to see the pictures transmitted, which makes the user feel that the privacy is damaged, which is inconvenient to use.

When the wireless transmission method is used for data exchange, after the wireless transmission exchange method of the smart mobile phone cannot be exchanged, the original data source must delete the data and cause the user who wants to exchange the data. Inconvenience, because most users who exchange data will hope that they will be the only ones who can use this information. Therefore, when data exchange is carried out, how to ensure that the information is actually exchanged to maintain the one-off exchange of data. (That is, the information exchanged has been deleted from the original source, and there is no longer a chance to exchange the information with others). It is also the creative direction that must be considered.

In view of this, the main object of the present invention is to provide a method for exchanging data by using a two-dimensional bar code, and transmitting data through wireless transmission and two-dimensional bar code mode, thereby avoiding data being received and applied by other parties during the transmission process. And the information exchanged will be deleted from the original source of information, and the data exchange can be maintained at one time.

In order to achieve the above object, the present invention provides a method for exchanging data by using a two-dimensional barcode for data exchange between a first device and a second device, and the first device stores a first data, and the second device The device stores a second data; the data exchange is performed by the first device, and includes the following steps: A. compiling the first data into a first two-dimensional barcode; B. outputting the first two-dimensional barcode; C. detecting whether the second device outputs a second two-dimensional barcode; if not, proceeding to step C; if yes, capturing the second two-dimensional barcode; D. interpreting the second two-dimensional barcode, and Obtaining the second data; E. storing the second data and deleting the first data.

Thereby, through the above design, the advantages of wireless transmission can be effectively provided, and the generation of wireless signals can be avoided, and the one-off of data exchange can be maintained.

In order to more clearly illustrate the invention, the preferred embodiment Detailed description is as follows.

The method for exchanging data by using a two-dimensional barcode is mainly applicable to data exchange between a first device and a second device. Referring to FIG. 1, the first device 10 and the first embodiment in the preferred embodiment of the present invention The second device 20 is a smart phone and each has a program for compiling and interpreting the two-dimensional bar code, and the first device 10 stores a first data, and the second device 20 stores a second data. In this embodiment, the first device 10 is placed opposite to the second device 20 (ie, the screen 12 faces the screen 22). The following uses the first device 10 as an example. In this embodiment, the second device is used as an example. The device 20 is operated in the same manner, so the first device 10 is used for the embodiment, but in fact, the data exchange method of the present invention can be used for the devices 10 and 20 respectively. Please refer to the flowchart of FIG. 2 together. And the method includes the following steps:

A. Using the program to compile the first data into a first two-dimensional barcode.

In the embodiment, the two-dimensional barcode is an example of a Quick Response Code (QR Code). Of course, in actual implementation, in addition to using the fast response code, a two-dimensional barcode such as a Hanxin code or a PDF417 code can be used instead.

B. Referring to FIG. 3, the first two-dimensional barcode is outputted on its screen 12.

C. Detecting whether the second device 20 outputs a second two-dimensional barcode.

If no, proceed to step C; if yes, the second two-dimensional barcode is captured; in this embodiment, the first device 10 is Detected through the front photographic lens 14 Detecting whether the second two-dimensional barcode is displayed on the screen 22 of the second device 20, and if the second two-dimensional barcode is displayed on the screen 22, capturing the image of the second two-dimensional barcode by using the front photographic lens 14 .

D. Using the program to interpret the second two-dimensional barcode captured in step C to obtain the second data.

E. Store the second data and delete the first data.

In this way, through the foregoing method of exchanging data by using the two-dimensional bar code, in the process of data transmission, when the data is exchanged and the other party's data is obtained, the original data is deleted, so as to achieve the purpose of ensuring the data is one-off. In summary, when the first device 10 performs the related data exchange operation, the second device 20 also performs the peer-to-peer response, and the above steps can also be used to learn that the data of the second device 20 is exchanged after the data is exchanged. The original information will also be deleted, and the same purpose is still required for the one-off purpose.

In addition, in addition to the above method, please refer to FIG. 4, which is a method for exchanging data by using a two-dimensional barcode according to a second preferred embodiment of the present invention. In this embodiment, the first device 10 is also taken as an example for description. And the screen 12 of the first device 10 is divided into a data display area 121 and a status display area 122 as shown in FIG. 5, and the method includes the following steps:

A. Using the program to compile the first data into a first two-dimensional barcode.

B. Referring to FIG. 5, the first two-dimensional barcode is outputted on the data display area 121 of the screen 12.

C. Detecting whether the second device 20 outputs a second two-dimensional barcode.

If not, proceeding to step C; if yes, capturing the second two-dimensional barcode and detecting whether the second device 20 has captured the first two-dimensional barcode within a predetermined time; if not, deleting The second two-dimensional barcode is re-executed in step C.

If yes, proceed to the next step.

In this embodiment, after the first device 10 captures the second two-dimensional barcode, as shown in FIG. 5, the state display area 122 of the screen 12 displays a set of two-dimensional barcodes, and the two-dimensional barcode A first notification message is provided to inform the other party that the data has been received. Therefore, in the step of detecting, the first device 10 detects whether a second notification message has been displayed on the status display area of the second device 20 to notify the other party that the data has been received within a predetermined time. The 2D barcode. If yes, proceed to the next step. If not, the second two-dimensional barcode is deleted, and step C is re-executed.

D. Using the program to interpret the second two-dimensional barcode captured in step C to obtain the second data, and confirm whether the second data is the data that is needed by itself; if not, delete the first Second, and re-execute step C.

If yes, it is detected whether the first data is the data required by the second device 20; if not, the second data is deleted, and step C is re-executed.

If yes, proceed to the next step.

In this embodiment, when the first device 10 confirms that the second data is required When the desired data is displayed, the status display area 122 of the screen 12 displays another set of two-dimensional barcodes, and the first two-dimensional barcodes have a first confirmation message for indicating that the other party's data has been confirmed. Therefore, in this step, the first device 10 detects whether a second confirmation message indicating that the other party's data has been confirmed is displayed within a predetermined time zone of the second device 20. QR code. If yes, proceed to the next step. If not, delete the second data and perform step C again. In addition, in the embodiment, when the first device 10 detects the status display area of the second device 20, the second device 20 also detects whether the first device 10 has a display to notify the other party that the data has been confirmed. The 2D barcode of the first confirmation message must be confirmed after the second device is confirmed. If there is no 2D barcode confirmed by one party, the data exchange will not be established. There will be no exchange to ensure the correctness of the data exchange.

E. Store the second data and delete the first data.

Furthermore, in addition to the advantages of the first preferred embodiment, in the data exchange process, the first device 10 and the second device are used in the data exchange process according to the second preferred embodiment. When the device 20 is displaced by the displacement, and the first two-dimensional barcode or the second two-dimensional barcode cannot be acquired, there is no data exchange error.

In addition, the second preferred embodiment of the present invention not only uses the two-dimensional barcode as the message communication, but also graphically represents the various messages described above. For example, referring to FIG. 6, the first device 10 can display a graphic on the status display area 122 of the screen 12 to indicate that the other party has received the first notification of the data. The message is then displayed with an additional graphic (ie, two graphics on the screen) to indicate the first confirmation message that the other party's data has been confirmed. Of course, in actual implementation, different graphics or different numbers of graphics can be used to indicate the message to be notified to achieve the same purpose.
