PDF documents may contain crucial information requiring viewing and/or copying to be controlled. Previously, software systems have been designed trying various different methods of protecting such documents and the information that they contain. Commonly, such systems involved the use of passwords that were distributed to users, but many programs can now crack those passwords and make their information readily accessible.
Lizard Safeguard PDF Security does away with passwords and is still able to protect your documents by using secretly managed decryption keys. With this application you can control the number of persons with access to a document, who can print which documents, how many times he/she can make prints, and also determine the number of times a document is viewed by an individual user.
Documents that have been protected by a publisher can never be saved, modified, copied or shared in an uncontrolled format. Also, screen grabbing, print to file and print screen features can be resisted by this DRM security application.
Lizard Safeguard PDF Security has capabilities which enable the publisher to ...
... determine the expiry dates of subscriptions to specific documents or groups of documents, and also user accounts. This capability allows the publisher to limit a subscriber's access to documents outside of licensed dates and times.
Imposing DRM on documents creates many challenges that are addressed by LockLizard PDF DRM Security.
LockLizard PDF DRM Security overcomes the weaknesses of passwords through the use of licenses. A license is given to the user or subscriber in the form of a hidden decryption key which is stored encrypted on the user's computer's hard disk. Whenever authentication is needed the software verifies the rights to use the key to determine if the user is still authorized to use a specific PDF document or publication.
Many PDF software suites and customers experience problems with plug-ins/outs. When we examine plug-ins, we find they often require add-on codes to verify that their security protocols have been observed. The downside is that those codes can be cracked by hackers, rendering the apparent security of the document useless. Plug-outs, on the other hand, are very resistant to modification, and therefore any slight change may result in the malfunctioning of the whole security system. LockLizard PDF DRM Security overcomes this through the use of a PDF DRM Viewer which uses the Foxit engine software toolkit directly to eliminate plug-ins and plug-outs.
LockLizard PDF DRM Security also has the added advantage of preventing unauthorized printing of PDF documents. Their DRM offers functionality by which watermarks are applied to a printed document with the details of the user making the print. Such details can include the name of the computer owner, his/her email address and the date and time when the printing was done. This information may be used by the publisher of the document to press charges against the source of pirate copiers.
