    • SmartAM Information Ecology Context• UMA/SmartAM Context Content User ‣ Provide an advance system to allow internet user to protect and share online information ‣ Prevent of lost of user privacy ‣ Adhere to the international privacy regulations ‣ Secure online information (access control) 6
    • SmartAM Information Ecology Context• UMA/SmartAM Content Content User ‣ Authorizing User information ‣ Authorizing User’s Web resource info ‣ Authorization Policies ‣ Requesting Parties Information ‣ Analytics information (who, when, what) 7

    • Understand the nature of data sharing policy in distributed environment• UMA model centralizes the authorization policies for all the Authorizing Users distributed web resource (protected resource).• The externalization of the policies introduces a new level of complexity because the user must (mentally) map the authorization structure for each resource, in more sophisticate one.• This new layer must be able to abstracting the existent, although it must be able to enhance the control on the information that will be shared.• Increasing of Protected resources and requesting parties could be mentally difficult for the user to maintain control in practice on the information. 11
    • Risks• Lost of Privacy• Exploit of online personal Information• Security breach 12
    • Enhance Privacy Control through visualization• As result a context authorization policy and a governor system is definitely desirable.• We introduce two new design concepts: ‣ UMA Connection ‣ UMA Control bridge TM• A visualization tool is necessary to facilitate the creation of the sharing policy and the control of the privacy. 13
    • UMA Connection• An UMA Connection defines a context of the data sharing policy. ‣ It’s a set of objects, including Contacts, authorized Apps and allowed actions on a specific resource. ‣ It can include access restrictions (i.e. period validity) and/or Trusted Claims request to restrict access based on subject’s information.• An UMA Connection is fundamental to enhance user control for what purpose the information will be revealed.• UMA Connection uses a visualization approach which helps user to define an appropriate context.• An Authorizing User can create a Connection for him-self or for others.• A Connection doesn’t incapsulate other connections. 14

    • UMA Control bridge • UMA Control bridge ‣ Is designed to adhere to the user-centric identity paradigm. ‣ Provides a primary user interface for control Resources, Connections, Apps and requesters. ‣ Provides a dashboard with main statistic information about connection, shared data, etc. ‣ Incorporates a single view of these main controls, including a notification bar for new access request. ‣ Provides 3-steps actions to get access to specific view, excluding optional view.UMA Control bridge TM 17
