Licensing controls also enable you to lock PDFs to specific devices and log document use. The main reason however is that you need protection for your PDF documents beyond what encryption provides.

The most likely reason being is that you want to have some control of your PDF documents once they have been decrypted for example whether a recipient can copy text from your document. This may be because the information is privileged for a certain group of people or you are selling information that you do not want to be distributed at your cost.

Well, at the basic level you could use a product like Adobe Acrobat. However, it is wise to bear in mind that there are tools freely available on the Internet that remove the copy controls you have applied literally within seconds. If you are serious about protecting your documents then you will probably want to purchase a PDF file security product that is not password based — read PDF password protection to see why — and uses US Government strength encryption. Download PDF file security software that uses US Government strength encryption, digital rights management controls, and does not use either passwords or plug-ins to secure your PDF documents.

Most of these programs however only provide standard PDF password protection. The other main disadvantage of this approach is that you have to upload unprotected PDF files to a cloud server where they could be easily compromized. This ensures your secure PDFs are always under your control.

PDF password protection has been the traditional way to impose PDF digital rights management controls on PDF document users, but it has a number of drawbacks.

Users can still add comments to PDF files if you allow this option , but PDF content is always protected from editing ensuring that your original content cannot be altered in any way. In some PDF protection products, if editing is disabled you can still highlight and copy text. Safeguard stops users from copying text and other content within a document — there is no copy paste option available and text cannot be highlighted for selection so it cannot be copied and pasted into other applications.

Unfortunately there are many free screen grabbing or screen capture applications available that users can download to easily bypass this restriction. Safeguard stops screenshots being taken by common third party software applications. It uses many different methods including a screen mask that is overlaid over the protected PDF document if the mouse cursor is moved to another active application.

No PDF DRM product however can stop all screenshots users can just take photographs of the screen so it is recommended that document publishers apply dynamic watermarks as a copying deterrent. Safeguard enables document publishers to expire PDF files so they can no longer be used after a certain amount of time. The following options are available:. You might for example want a user to be able to use your documents for a 15 day trial period but those documents will expire on a fixed date regardless if the trial period is used or not.

Being able to revoke PDF files is an important part of any document security solution. There may be times when the wrong document was published, a user has left your company, or you think a specific document has been compromised.

Safeguard enables you to revoke PDF files instantly the document must be set to check with the administration system each time it is opened , or you can revoke users so all documents they have access to become inaccessible. If you have created PDF files that only check with the administration system every n days then PDF revocation will only take place once a check has occurred.

With Safeguard, PDF files can be revoked no matter where they are located. You can also revoke access to multiple PDF files instantly and group documents into publications to make revocation easier for common groups of documents. No DRM system is fool-proof. Even if screenshots are prevented, users can take photographs of the screen using a camera.

Similarly, if printing is allowed, users can print and scan back in printed documents. You can use different watermarks for viewed and printed documents and both text and image watermarks are supported.

PDF watermarks can be displayed behind content so they are less obtrusive to the user and you can choose not to display watermarks on the first page of a document if you have a cover image that you want to leave unmarked.
