RMS Viewer enables Windows RT Clients to consume Microsoft Windows Rights Management protected documents received by mail or any other application. Windows Information Rights Management protects typical office documents using strong encryption and allows the use of these documents only on dedicated enrolled Microsoft Windows Machines. But because of the nature of these documents it is critical for a corporation to enable its employees to consume the documents also on corporate enabled mobile devices like Smartphones or Tablets to be able to be informed in time when travelling. The RMS Viewer App registers itself to the file types available for RMS and when rights management protection is detected, the mobile app sends the protected document to a RMS Rendering server hosted in the corporate network. The RMS Rendering Server will decrypt and convert the document if the user has permissions to view the document. The converted document will be received by the mobile app and displayed within an app viewer, which will not allow to print or forward the protected document.
