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.
See How to remove a watermark from a PDF. This is done at the user level or a global level for all users. In this way you can easily restrict all users to viewing protected PDF files from say your office location in the US. This is particularly useful if users have laptops which they are allowed to take home — locked PDF files can then only be viewed at the office and not when the user is at home or at other locations where they could be shown to others.
This is useful if you want to check whether a particular user has viewed a document yet especially if they claim to have not received it. You may therefore only want to track PDF use for specific documents otherwise users will have to be constantly online.
Locklizard provides secure PDF hosting with Web Publisher protected PDF files are stored on a cloud server either hosted by Locklizard or yourselves or you can distribute PDF files securely as you would any other file. Many providers offering secure PDF hosting or enable you to secure PDF files online, but these are not as secure as you may think. Your unprotected PDF files are uploaded to a server where they are stored, encrypted and DRM controls applied, before being stored again in protected format.
This may be fine for ebooks but what about sensitive and confidential company documents? Do you really want them sitting on a server in unprotected format for any length of time? Your PDF files can never be compromised by server vulnerabilities as they are encrypted locally, uploaded via SSL, and stored encrypted on the server. If you prefer to host secure PDF files yourself then you can distribute them just like any other file email, USB, web site download, etc.
It does not matter who has access to your secure PDF files because they are encrypted and can only be viewed by authorized users. Log in Social login does not work in incognito and private browsers.
