Digital Rights Management (DRM)

 

  Access management variably called, access control, terms and conditions, licensing
conditions and Digital Rights Management (DRM) refers to control of access to digital libraries. Digital Rights Management (DRM) is a system of solutions created or designed as a means to prevent unauthorized access, duplication and illegal distribution of copyrighted digital media. The DRM technology was created for the publishers as a means to stop illegal reproduction and distribution of their products. In online environment, the scope of DRM can be leveraged to control access to and usage of digital objects and to impose restrictions on their misuse.
Four distinct aspects of access management are: i) license agreements and policies; ii) user authentication and authorization); iii) accuracy and integrity of digital content; and iv) accessibility including permissions to operate on digital objects or its metadata. License agreements and policies are negotiated between the publishers and library consortia coordinators for providing access to digital libraries. Users are authenticated and authorized to access content of a digital library as per the terms and conditions of the license agreement. While users, duly authenticated, are allowed access to information according to their nature of clearances and authority, unauthorized users are blocked from accessing information. Confidentiality is of paramount importance in digital libraries containing national defence information or highly proprietary information. Accuracy or integrity means the continuing integrity of information stored in digital object servers. Digital library must not allow accidental or intentional corruption of information stored in it by unauthorized users or programs. Accessibility means that a secure computer system must keep information available to its users. The hardware and software of a computer system should keep working efficiently and the system should be able to recover quickly in case of disaster. Moreover, users are given access to digital contents with permissions to download (in case of users) and to add, edit, delete or amend in case of editors(Russell, D and Gangemi, G.T., 1991)
