Dear All, I am new to this group and spare me if I am asking a dumb question. I am wondering, Is there any way in UMA to capture the dynamic context of the resource owner to provide context-aware authorization? I have the following use case, "Alice's mom will get access to online CC camera hosted in Alice's apartment, Only if Alice is out of her apartment " I know XACML is used to capture the context of the Requester (e.g., subject of XACML, in this case Alice's Mom). But I do not know is there any mechanism in XACML to capture the dynamic context (in our case, context is location) of the resource owner (in this case, Alice ) for authorization decision. Can anyone advise me on this ? Any comment will be appreciated. Kind regards, Jabed
