Do users need to be online to access Vitrium-protected content?

Yes, users need to be online initially to access Vitrium-protected content.

For protected documents & images, there is an "offline access" option available for users, however, this option is currently not available for video & audio content. This is due to the significant amount of browser memory needed for offline viewing.

 

Will Vitrium-protected content open on iPad and Android tablets?

 

Yes! Vitrium offers a secure web version for all the different types of content that it protects: documents, images, videos, and audio. These are all compatible with iPad and Android tablets, as well as iPhones and Android phones. 

How can I customize the web viewer login form?

You can add your logo, a text description, and change the banner color of the login page in the Web Viewer Settings in your Vitrium Security account.

Further details on how to make these changes can be found in the Vitrium Security Admin Manual: https://view.protectedpdf.com/NpcYTE#bookmark=web%20viewer%20settings 

 

 

 

 

 

Are Vitrium-protected eBooks compatible with eBook readers?

No, not unless the eBook reader has a built-in browser. Most eBook readers use a proprietary format, often with their own DRM capabilities.  

However, if the eBook reader has a decent web browser, it may be able to open Vitrium-protected content.

Can we track how many times we clear someone's usage?

Yes, this is made possible in Vitrium by the "clear use tracking feature".

**Important Note**
Although you may need to clear someone's usage once in a while to reset their limits because they've changed computers or lost a phone or tablet, you shouldn't need to clear their usage too often. Some users may start to take advantage of your kindness in clearing their usage so the "clear use tracking" feature will allow you to monitor this.  

TRACKING CLEAR USE

Tip 1: Go to the History tab of the Clear Use window to review how often usage was cleared 

Tip 2: Ensure you add detailed information every time you clear a person's usage 

 

What is the Global Object Security policy and what do I need to do when I see this message?

The Global Object Security (GOS) policy is a setting in Adobe Reader and Adobe Acrobat that controls how cookies in Adobe products behave. The default setting is to "enable global object security policy" which means that every time someone renames a file or moves a file to a different location, a different cookie is created each time. Since Vitrium's content security solution relies on these cookies to track the number of 'devices' that a user opens the secured content on, it is STRONGLY recommended that end users disable this feature. 

How to disable the Global Object Security Policy:

  1. In Adobe, go to Edit > Preferences
  2. Click the JavaScript tab
  3. De-select (uncheck) the "global object security policy" field
  4. Click OK

Users will only need to do this once for one computer. If they wish to open the protected PDF file on a 2nd computer (assuming they have permission to do so), then they will need to disable the GOS policy in Adobe on the other computer as well. 

To learn more about disabling the GOS check out 'How to Support Your End-Users' guide or 'How to Open a Vitrium Protected PDF with Adobe Reader' videos.

Why do users need to disable the Global Object Security Policy in Adobe?

Because otherwise the user may exceed the limit that was set for them in their DRM policy and they will encounter the vc3 error message (You have exceeded your PDF or browser limit) even if they have only opened the file on the same computer.

By disabling Adobe's GOS policy, the user can then safely move the protected file from one folder to another, or rename the protected file to something else, but not reach their limit as the cookie is saved with the file on that same computer. 

Can I remove the Adobe global object security policy pop-up message?

Yes, you can remove this message but we only recommend this to Vitrium customers who DO NOT set a PDF limit in their DRM policy settings.

To remove the message: 

  1. In Vitrium, create a new Content Settings
  2. Click the Advanced Options tab
  3. Check "Set Acrobat cookie policy"
  4. For both Acrobat 10.0 and Acrobat 11.0+, select "No prompt and no close document" for both fields
  5. Ensure all your other Content Settings are created (i.e. no print, no copy, etc.)
  6. Click Save & Exit
  7. Then apply this new Content Setting to all files or only those files where you do not require a PDF limit for users

Using Vitrium's VersionUnique API, this content setting can be changed/overridden by including this parameter:

"DocPolicyOverride":
    {
    "AcroJsGosBehaviourType": "NoPromptAndNoClose",
    "AcroJsGosUnlimitedBehaviourType": "NoPromptAndNoClose"
   }

Where:

AcroJsGosBehaviourType would apply to Acrobat v10 and earlier releases
AcroJsGosUnlimitedBehaviourType would apply to Acrobat v11 and newer releases

Definition of each Acrobat GOS policy setting:

  • PromptAndCloseDocument - this will prompt the user if they don't have the global object security policy setting disabled and will close the document until they make this change. This is the default setting. 
  • PromptOnly - this will prompt the user if they don't have the global object security policy setting disabled but will not close the document. You then run the risk of the user reaching their PDF limit if they did not follow the instructions.
  • PromptOnce - this will prompt the user only once if they don't have the global object security policy setting disabled but will not close the document. The prompt will appear once per document, not per device. You then run the risk of the user reaching their PDF limit if they did not follow the instructions.
  • NoPromptAndNoClose - this will neither prompt the user nor close the document and is only recommended in scenarios where you DO NOT require setting a PDF limit for users. When set, a new deviceId/Tracking Id is generated when the user first opens the document; a new deviceId is generated if the user then renames and opens that document; and a new deviceId is generated if the user moves the document to a new folder and opens it from there. So be aware that a small device limit (1 or 2) can be exceeded by a user who simply renames or moves the Protected PDF on disk.

 

What happens if a User forwards the content to someone else?

Vitrium Security offers two types of secured outputs: (1) a secure web link and (2) a protected PDF file (for document conversions only). Both methods can be shared with others but since Vitrium Security focuses on DRM and protecting content, there are multiple ways to prevent unauthorized viewing of the content: requiring authentication, setting passwords, setting PDF or browser limits (similar to device limits), setting IP address limits, setting content limits, and more.  Here’s what may occur if the customer utilizes any one of these methods:

 

  1. The user is confronted with a login page or notification page – the login page may ask the user to enter a password, a license key, or some other type of credential, or it may be a notification page indicating that some other type of authentication is required. This will all depend on what type of implementation was set up. If the person receiving the shared content is not authenticated, they will see a login screen or notification page when they try to open the file or access the content.

 

  1. The user is confronted with an error message – even if the user shared the password with someone else, the customer can set a number of different types of DRM policies that will prevent unauthorized sharing of the content: PDF or browser limits, IP address limits, content limits, and more.

 

Content and files that are protected with Vitrium Security are protected no matter where they reside or where they are saved – on a local computer, network drive, file sharing application, or a mobile device – the content remains protected until that authentication occurs.

How do I save a copy for offline use?

For the secured web documents to work offline, a copy needs to be saved in the user's browser cache. This is a quick video shows how you can save a copy on your browser cache for offline use of the secured web document (Vitrium's Web Viewer):

Basically, the web document needs to be saved in the browser’s cache (as cookies) so it can be used later when the User decides to access it ‘offline.’ You’ll notice in the video also the delete button to remove this ‘saved copy’ from the browser for when their use is done.

We highly advise for the User to clean up their browser cache soon after they’re done reading the document offline as it will eventually fill up their browser caching storage (which gets stored on the hard drive). Simply put, if they save all  the documents they have permission to for offline use, the browser cache can get quite large and it will start to slow down their computer speed for processing things.

Here’s an article online that you can read for more  clarification on the browser cache: http://www.makeuseof.com/tag/browser-cache-makeuseof-explains/

Can we prevent a user from saving the file?

Vitrium Security offers two types of secured outputs: (1) a secure web link and (2) a protected PDF file (for document conversions only). The concept of ‘saving a file’ is different for each type of output:

 

Secure Web Link

Although you can ‘save’ a web link by bookmarking it, you cannot download the content. The Vitrium customer can set a number of days of ‘offline access’ as part of the DRM policy setting but even if that is allowed, the user can click the ‘Save to browser’ button in the web viewer and the content gets saved in the browser’s cache or memory for offline viewing. Again, the content does not get downloaded anywhere.

 

Protected PDF File

Content and files that are protected with Vitrium Security are protected no matter where they reside or where they are saved – on a local computer, network drive, file sharing application, or a mobile device – the security travels with the protected PDF document. So theoretically, the user can save the file but if they save it to a public computer or shared network, the content itself cannot be viewed or accessed unless the person is authenticated. This is why Vitrium Security can be an ideal solution to combine with an existing content management or document management system.

 

When "Fillable PDF" forms are protected, after successfully unlocking the content, the user might need to enter data into the form(s) and save that entered data to a new file and send it back to someone. The new PDF is protected in the same way as the original PDF and the same DRM policy remains in effect.
