Subject: Re: [DG-IDoT] Common identity standard
Hi Ranjan,I suppose you meant identifier, not identity.Identity is often defined as 'set of attributes related to an entity' (ISO/IEC 29115, ITU-T X.1254, OpenID Connect, etc.). It can be represented in many ways, but X.509 (ASN.1), SAML(XML), ID Token (JSON) are some of the popular formats.There is no single standard for identifier.However, we can represent them as URIs or URNs. XRI is another candidate.One advantage of using URI/XRI is that you can resolve it to get more data about it.My 2c.Nat Sakimura

Rather we need to have a flexible schema and a universal discovery mechanism for identity attributes based on the type of service an entity is interested in interacting with. Such a framework could be configured with hierarchical rule sets which govern what 'kinds' of entities are authorized to interact with the entity domain the rules govern and with 'what capacity'.would be interested in hearing other's thoughts.AnindaOn Thu, Jul 16, 2015 at 2:38 PM, Ranjan Jain (ranjain) <ranjain@cisco.com> wrote:Hey y’all,Hope everyone is doing well. Just wanted to bounce a question which I’m consistently getting asked around Identity, IoT perspective. Is there any industry standard in place or in works which can be used as a common standard across multiple identities. What I mean by this is that humans have SSN as an identity while a thermostat may have serial number while a network device may have a Mac ID as their identity. So, while individually they all have their own identity standard, when in the IoT world, all these entities start interacting with each other, how do we translate one identity into another or how will one identity interact with another identity in a standards way?ThanksRanjan
