BoomerangDocTM is an app that works like a mobile DRM system. You have the ability to share and unshare documents on a whim. Your sent documents cannot be saved or redistributed by the receiver and you can always take them back.BoomerangDocTM also allows you to remotely manage and track users activities with advanced audit trail and geo location features. This gives you total control of all file permissions including redistribution, copying, sharing, saving and printing.
