Patent Searching and Data


Title:
DATA TRANSMISSION METHOD AND APPARATUS, TERMINAL DEVICE AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/164211
Kind Code:
A1
Abstract:
The present application is applicable in the technical field of data processing, and provided thereby are a data transmission method and apparatus, a terminal device and a medium, the method comprising: performing fragment extraction according to the file type and file size of data to be encrypted to obtain multiple data fragments and position information; randomly sorting and combining the data fragments to obtain combined data as well as position information of each data fragment in the combined data; searching for an irreversible encryption algorithm and reversible encryption algorithm corresponding to the file size of the combined data; processing the combined data on the basis of the irreversible encryption algorithm to obtain a check code, and processing the position information on the basis of the reversible encryption algorithm to obtain encryption information; and performing data transmission on the check code and encryption information together with the data to be encrypted. Compared to a fixed single processing algorithm, the embodiment of the present application increases the cracking difficulty index thereof so that criminals cannot predict possibly used algorithms and possible results, thus it is more difficult to crack a corresponding process.
