Dynamic barcode-based data exchange method

Abstract

Disclosed in the invention is a dynamic bar code-based data exchange method. A data encoding module, a service logic module, and a data decoding module and the like are arranged. According to the invention, on the basis of an encoding parameter, set by a user, of a dynamic bar code as well as a user data type and a data size, the user data are segmented and encoded and then the processed data are written in all frames of the dynamic bar code; a receiving data terminal device scans all frame images of the dynamic bar code, parses data of each frame of the dynamic bar code, and restores the data into original data according to a frame order. Because data exchanging is carried out based on the dynamic bar code, the simple and rapid capacity-extensible data exchange mode and service can be provided for the user.

Description

technical field [0001] The invention relates to mobile terminals and the field of barcode technology, in particular to a data exchange method based on a dynamic barcode. Background technique [0002] With the development of mobile terminal technology and barcode technology, especially the development of terminal camera and scanning capabilities, it is feasible to provide a data exchange method based on a dynamic barcode. [0003] The current traditional Internet data exchange method is commonly used to set up a network server and assign permissions to users to download. , did not realize end-to-end automatic exchange of data. [0004] The traditional barcode data exchange can only adapt to small-capacity data exchange, and the barcode data capacity is small. For example, the QR code can encode up to about 4K characters, and with the increase of encoded characters, the graphics of the barcode will become more and more difficult to identify. And resolution, the requirements ...

[0003] The current traditional Internet data exchange method is commonly used to set up a network server and assign permissions to users to download. , does not realize the automatic exchange of end-to-end data

[0004] The traditional barcode data exchange can only adapt to small-capacity data exchange, and the barcode data capacity is small. For example, the QR code can encode up to about 4K characters, and with the increase of encoded characters, the graphics of the barcode will become more and more difficult to identify. And resolution, the requirements for the light of the use environment and the scanning camera are getting higher and higher, which limits the application of large-capacity data exchange, and the dynamic electronic barcode provides the feasibility of large-capacity data exchange for the barcode-based data exchange method sex

[0005] With the development of the wireless Internet, the range of terminals has expanded to various portable devices such as mobile phones and tablet computers. It is also a common means of data exchange, such as data exchange of wireless Bluetooth technology, but there are differences in the software and hardware of the terminal, user habits, and the security of short-distance wireless technology, making data exchange of short-distance wireless technology difficult. The user experience is poor, and it has not been well applied so far

[0006] At the same time, due to technical maturity and cost, terminals supporting short-range wireless technology have not been popularized on a large scale so far, and cannot be transferred and exchanged between terminals supporting short-range wireless technology and terminals that do not support short-range wireless technology such as NFC technology Data, user experience is further reduced
