Abstract

The embodiment of the invention provides a file sharing system, which comprises a first electronic device used for obtaining sharing setting information of a first file and sending the first file andthe sharing setting information to a server, the server used for writing the sharing setting information into metadata information of the first file to obtain a second file, encrypting the second fileby using the password to obtain an encrypted file, performing associated storage on the information abstract value of the shared setting information, the access permission information and the password to generate an access address of the encrypted file, and sending the access address to the first electronic device; a second electronic device used for downloading an encrypted file pointed by the access address and sending the information abstract value and visitor information to the server, wherein the server is also used for verifying whether the visitor corresponding to the visitor information has the access permission based on the access permission information, and if so, sending the password to the second electronic device or sending a second file obtained by decryption to the second electronic equipment. Therefore, the security of the shared file is improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a file sharing system. Background technique [0002] For work and study, users often need to share various files. Wherein, the files to be shared include but are not limited to: word documents, PDF (Portable Document Format, portable document format) documents and PPT (PowerPoint, presentation) documents. [0003] The current file sharing method is often as follows: User A uploads the file a to be shared to the cloud server. Then, user A encrypts the file a to be shared through the cloud server to obtain the encrypted file. Furthermore, user A can obtain the access address (ie link address) and password corresponding to the encrypted file. After that, user A needs to send the access address and password to user B. In this way, after user B opens the webpage corresponding to the access address, he can input the password on the webpage, so as to realize the access to the file...
