How Word 2010 Documents Encrypt and restrict editing features

In Word 2010, we can click on the "File" tab and select "Info"-"permission"-"protect Document" to see several security features that Word provides: Mark as final, encrypt with password, restrict editing, restrict permissions by people, add digital signatures.

　　How to use Word 2010 document encryption and limit editing

1, marked as final state

Marking as final enables the Word document to be marked as read-only, and office automatically disables all editing features when it opens a document that has been marked as final. However, marking the final state is not a security feature, and anyone can cancel the final state of the document in the same way. In particular, Word 2010, when you open a document that is marked as final, prompts the document to appear at the top of the window to be marked as final and to display the still edit button. As a result, it is not appropriate to protect important documents by marking them as final in order to fool the rookie and preventing inadvertent user changes to the document. Also, documents marked as final in Word 2007/2010 can still be edited directly in Office2003, because Word 2003 is not marked as the final State feature.

　2, encryption with the password

Encrypting with a password is password-protected for Office documents, which is a popular protection feature in earlier versions of Office. But the biggest problem with password protection is that users can easily forget their passwords. Once you forget your password, you can only use third-party tools such as advanced Office Password Recovery for password cracking, which can damage your document.

　　3. Limit editing

Restricting the editing feature provides three options: formatting restrictions, editing restrictions, and starting mandatory protection. Formatting restrictions can selectively restrict formatting editing options, we can customize the formatting options by clicking "Settings" below it; editing restrictions can selectively restrict the type of document editing, including "Tracked changes", "annotation", "Fill out form", and "do not allow any changes (read only)" If we make a form, Just want the other person to fill out the specified item, do not want to modify the problem, with this feature, we can click on the "Exceptions (optional)" and "more users" below it for limited user customization; Start force protection protects documents by means of password protection or user authentication, which requires Information Rights management ( IRM) is supported.

　　4. Restrict the authority by personnel

You can restrict permissions for Office documents through Windowsliveid or Windows user accounts by people restricted permissions. We can choose to protect Office documents by using a set of administrative credentials issued by the enterprise or by manually setting restricted access. This feature also requires Information Rights Management (IRM) support. If you want to use Information Rights Management (IRM), we must first configure the Windows Rights Management Services client program. This program is already included in the Windows7/vista system, and the Windows XP system needs to be downloaded separately for installation.

　　5, add digital signature

Adding digital signatures is also a popular security protection feature. Digital signatures are based on cryptography to help mitigate the risks associated with business transactions and document security. To create your own digital signature, we must first obtain a digital certificate that will be used to prove the identity of the individual, typically obtained from a trusted certification authority (CA). If we do not have our own digital certificate, we can get it through the Microsoft partner officemarketplace or insert a signature line or stamp signature line directly into office.
