Encrypted electronic document sharing method based on multi-level authorization

Abstract

The invention discloses an encrypted electronic document sharing method based on multi-level authorization, which comprises the following steps of: S1, creating identity information on a virtual platform, and obtaining corresponding identity identification information and an authorization code decryption private key; S2, obtaining a shared document file through a network, and encrypting the shared document file; and S3, enabling the virtual to platform performs identity authentication on the shared document file. The method has the beneficial effects that a basic document encryption scheme is provided, and meanwhile, an authorization management scheme of all use scenes is also provided; and under the environment of developing and using the universal reader, a purchaser and a reader sharing the document only need to grasp the familiar reader, a content provider and a platform provider only need to establish an authorization center, and even the authorization can be managed to a third-party authorization center, so that the technical difficulty that the content provider and the platform provider participate in document sharing is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to an encrypted electronic document sharing method based on multi-level authorization. Background technique [0002] Document sharing can allow multiple people to view and edit the same document at the same time; you can also download specified documents for a fee or for free through identity authentication on the document sharing platform. Documents in these two sharing methods are provided to end users in unencrypted or encrypted form , its encrypted format must download a dedicated reader to view. [0003] In encrypted document sharing, due to the different encryption schemes and the lack of a unified reader technical basis, users need to install multiple platform-specific readers to view documents on multiple platforms, and the operating habits and functions of each reader are quite different. Similarly, it affects the reading experience; at the same time, users canno...

Problems solved by technology

[0004] The problem is focused on the document reader, and the basic solution to the problem is to develop a general-purpose reader. With the development of digital reading, many large-scale professional general-purpose readers have been born. However, the reader products of these developers are currently In the field of shared documents, the main reason is the lack of mutual trust among the parties involved in document sharing: developers, customers, and sharing platforms
