Abstract

The invention relates to a document online preview method, device and equipment. According to the embodiment of the invention, a first preview request of a preview platform is received, and the first preview request comprises a unique identifier of an encrypted document and identity information of a preview user; based on the unique identifier of the encrypted document and the identity information of the preview user, the preview permission of the preview user to the encrypted document is verified; if the preview user has the preview permission, decrypting the encrypted document to obtain a plaintext document of the encrypted document; and the preview data of the plaintext document is sent to the preview platform, so that the preview platform displays the preview data to the preview user, online preview of the encrypted document is realized, the leakage risk of the document information is reduced, and the security of the document information is improved.

Description

technical field [0001] The present disclosure relates to the technical field of file management, and in particular, to a method, device and device for online preview of documents. Background technique [0002] With the development of computer networks, online transmission and sharing of documents are becoming more and more frequent, and users' demand for online preview of documents is increasingly strong. Online preview does not require downloading the original file, which can provide users with a more convenient reading experience. [0003] The existing document online preview technology focuses on the processing of the document content, and only supports the preview of the plaintext document, but cannot realize the preview of the encrypted document, the document information is easily leaked, and the security is poor. SUMMARY OF THE INVENTION [0004] In order to solve the above technical problems or at least partially solve the above technical problems, the present discl...
