Enterprise digital rights management system based on smart card

Electronic data access control in conventional digital rights management (DRM) systems is not suitable for company oriented DRM systems. Many enterprise digital rights management (EDRM) systems have therefore been developed, aiming to fulfill the requirements of companies. Using such systems, companies are able to regulate their digital content, allowing only authorized users to access and execute digital documents. All access and use of digital documents by such users is also logged into history files. This allows multiple authorized users to edit and modify shared digital content together; even cross departmental sharing and editing of digital content is made possible. In this work, we have proposed a system that is different to the EDRM system developed by Chen et al., Lin et al. and Chang et al.. Our system improves upon the systems mentioned previously and overcomes their drawbacks. A mechanism based on smart card has been used to design the new EDRM system, allowing it to be used in company operations with more flexibility and more convenience.
