Embodiment 1
[0025] see figure 1 , figure 2 , a security management method for enterprise-level electronic documents, the security management method comprising the following steps:
[0026] (1) Steps for transparent decryption of electronic documents:
[0028] B. Judging the encryption status of the electronic document: when the user creates or opens an electronic document, if the electronic document does not contain an encryption mark, then the electronic document is defined as a new document or a plain text document; if the electronic document contains an encryption mark, then the electronic document is defined as encrypted document;
[0029] C. Obtain authorization: the user obtains the authorization control policy information and obtains the authorization to read the document, then go to step D; if the a...
Embodiment 2
[0055] This embodiment is improved on the basis of the first embodiment, and the content of the same part as the first embodiment will not be described repeatedly.
[0056] see image 3 , in this embodiment, the security management method of enterprise-level electronic documents also includes the following steps:
[0057] 2) Steps for transparent encryption of electronic documents:
[0058] E. The user obtains the authorization control policy information and obtains the authorization to write the document, then go to step F; if the authorization to write the document is not obtained, the ciphertext document cannot be edited;
[0059] F. Users who are authorized to write documents have the right to obtain the authorization key, and transparently encrypt the ciphertext document according to the authorization key and save it.
[0060] In this embodiment, the user operates the client unit to read the authorization control policy information, and if authorized to write the docume...
