The Sony DADC User Rights Management Solution (URMS) is a highly flexible and secure licensing solution. Whether you're a publisher, content creator, retailer, library or handling a document management system, URMS will facilitate your business.

An API-based service, easily adapted to your individual needs, URMS comes with a development kit based on the Readium Rendering Engine. It offers a wide set of options to revoke, extend or renew your customer’s licenses without triggering their activity.

Why use Sony DADC User Rights Management Solution (URMS)?


There are many tools available to easily circumvent current DRMs. We call these “one-click” hacks and they contribute to widespread piracy.

Sony DADC's solution keeps easy "one-click" hacks off the market because their URMS is "renewable."


Sony DADC URMS is a lightweight, API-based solution both for encryption and decryption – you don’t need to license a server.

It’s designed to work with the Readium Foundation’s open-source e-reading rendering engine allowing reading app developers to have a seamless experience for their users.


This is perhaps the most important characteristic of URMS. 

URMS can do everything from ruthlessly lock a file down to enabling a wide range of sharing options, whether for paying consumers or for free distribution, across educational, professional, corporate, library and retail use-cases, supporting pay-per-download or subscription. Content owners have an endless array of choices to support current and future business models and marketing and promotional strategies - reducing friction with customers.
