In a dealing room we can find sensitive documents such as audit information, partner or contractor confidential information, information on business merger deals, and so forth. Such documents are generally shared on a time-limited basis with authorized users under condition that the information should not leave the room. What is therefore needed to maintain this status quo is a data leakage prevention mechanism. This data security protection should be one that can determine the duration of time (but which should also be extendable) that such documents should be made available to the authorized persons. It should also ensure that the use of the documents is logged.

Many data rooms have experienced problems with access control systems as they were/are not adequate in preventing people from making copies of sensitive documents. Another form of data leakage prevention was thus desired and it materialized in the form of digital rights management (DRM) controls. This security mechanism protects documents in data rooms by preventing the unauthorized making of unprotected copies or saving then forwarding them to other parties. DRM data security protection, also makes use of watermarks which help to identify if an authorized person in the dealing room printed a document and then photocopied it in order to distribute it to others.
DRM-based data leakage prevention systems will help you to create your own secure custom dealing room whereby you will have adequate control over document access and usage in the following ways: controlling copying, printing, and viewing whereby you determine when the documents can no longer be viewed/when they expire or even instantly revoke access. This form of data security protection looks to provide continuous document protection as opposed to other mechanisms that are plainly focused on preventing or stopping access to the documents but do not control their usage.

DRM is successful as a data security protection mechanism because it contains components that actively prevent the removal of set controls. DRM controls are embedded into the document and protected through the use of encryption. Documents can only be decrypted using a secure document viewer. Decryption takes place in memory, and decryption keys are retrieved from the documents owner's server where they are then kept encrypted in a secure local key store. The keystore is locked to individual authorized computers effectively preventing sharing. DRM does not allow multilevel security (MLS) whereby an authorized user can also decide who will have access to the documents.

As we can see, DRM and encryption provide adequate data leak prevention by effectively preventing the forwarding of uncontrolled information by authorized users; this means that you can now have a truly secure dealing room.
