Adobe Acrobat Reader DC
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.
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.
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
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.
Yes, this is made possible in Vitrium by the "clear use tracking feature".
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
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 Security'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:
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 the '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 on a new content setting:
This can also be done in an existing document content setting as long as the content setting has not been applied to more than 25 files. If it has been applied to more than 25 files, feel free to reach out to email@example.com to get the change made for you.
Using Vitrium Security's VersionUnique API, this content setting can be changed/overridden by including this parameter:
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:
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:
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.
If you would like to know more about these options, contact the Vitrium team. You can click on the ‘Contact us’ button at the top of this page.
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/
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.
We strongly believe in being responsive and accountable, which sets us apart from others in the industry.
