[0013] In order to make the purpose, technical solution and advantages of the present invention clearer, the specific implementation of the present invention will be described in detail below in conjunction with the accompanying drawings. Here, the schematic implementation and description of the present invention are used to explain the present invention, but not to limit the present invention.
[0014] The system is generally divided into two parts: the client and the application server. The detailed process of file md5 calculation and uploading is shown in the attached picture figure 1 shown.
[0015] When uploading, the client checks the local environment separately, and automatically determines the md5 calculation method, which is divided into one-time loading memory calculation and segmented parallel calculation. The obtained results cooperate with the cloud server to verify the authority and the existence of md5. After the client submits the form, the cloud server saves...
