Abstract: An electronic official document (EOD) processing method, wherein a work action set consisting of N work actions is defined, comprising: (1) selecting M work actions from the work action set, setting a corresponding working user for each selected work action, and sequencing all selected work actions into a workflow by order of execution; (2) inputting a to-be-processed EOD as a first EOD into the first work action in the workflow; (3) starting an integer i from 1 and increasing the integer i by 1 each time until the integer i reaches M, and executing the following every time the integer i is increased: the working user corresponding to the i-th work action performs an operation specified in the i-th work action on the No. i EOD, and stores the processing result as a No. i+1 EOD; and (4) outputting the No. M+1 electronic document as the processing result.

Abstract: The present invention discloses a kind of management method for digital rights, wherein, it comprises the following steps: Step S1: the original electronic file is encrypted on the server-side, and in the meantime, the flow code, the file unique identifier, the authorization locations and verification information is injected; Step S2: obtaining flow codes, file identifier, authorization locations and verification information from the encrypted file, and then conducting integrality verification thereon; step S3: After it is verified that there is no error, the related information is sent to the authorization server; S4: after receiving the injection information about the encrypted file, the authorization server conducting integrality verification firstly, then judging the type of encryption file according to the flow code, and generating an authorization file and sending the same according to the type; Step S5: a decryption tool obtaining the authorization file to conducting integrality verification on the aut

Abstract: Disclosed is a method for controlling online previewing of an e-book page, comprising the following steps of: encrypting, on a server end, an e-book based on content, and establishing an index file of a relationship between a page number and an encrypted object flow in the encrypted e-book, the index file comprising a page code, an object name, a starting location of the object in the file and the number of bytes of the object; when an encrypted file reader and the server end perform reading handshake, obtaining a range value of previewed page and the index file in advance; according to a range code of the previewed page and the index file, obtaining a data flow of an encrypted object page by page; performing, by the encrypted file reader, integrity verification on object data, and then decrypting, parsing, and displaying information of the preview page.
