Problems solved by technology

[0003] However, in the existing DRM technology, in order to prevent the electronic document from being illegally copied and used, the distributability of the number of copies of the electronic document is usually not considered, that is, after the electronic document is owned, the electronic document can only be opened on a limited device , it is forbidden to distribute certain copies of the document to others by copying; or there is no restriction on the document, and it can be freely copied
Neither of these two methods can reasonably protect the document
[0004] It can be seen that the existing DRM technology cannot realize the free distribution of electronic document copies on the basis of protecting digital copyright

Abstract

The invention discloses a method for managing electronic document rights of use. The method includes the steps that number information for recording the number of electronic documents is set for the electronic documents; a first user regards a positive integer smaller than or equal to the number as the number of the electronic documents to be distributed according to the number recorded by the number information of the electronic documents owned by the first user and sends the electronic documents and the number information in which the distribution number is recorded to a second user; the operation for subtracting the number of the electronic documents to be distributed from the number of the electronic documents owned by the first user is conducted; the second user acquires the number of the distributed electronic documents, and the electronic documents are used within the limit of the acquired number. By the adoption of the method, on the basis of protecting digital copyrights, the electronic documents in the number can be freely distributed.
