Hi Ranjan, <div><br></div><div>I suppose you meant identifier, not identity. </div>Identity is often defined as &#39;set of attributes related to an entity&#39; (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. <div><br></div><div>There is no single standard for identifier. </div><div>However, we can represent them as URIs or URNs. XRI is another candidate. </div><div><br></div><div>One advantage of using URI/XRI is that you can resolve it to get more data about it. </div><div><br></div><div>My 2c.  </div><div><br></div><div>Nat Sakimura <span></span><br><div><br><br>On Thursday, July 16, 2015, Aninda Bhunia &lt;<a href="mailto:abhunia@inc38.com">abhunia@inc38.com</a>&gt; wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi Ranjan,<div>You bring up interesting points but the question i believe, we need to ask, is why (if at all) do we need to &#39;exchange&#39; identity information and does it make practical sense to have just one common identity structure in the IoT ecosystem?</div><div><br></div><div>I dont think it would be practical nor scalable to have just one common identity structure. 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.

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?</div><div><br></div><div>Thanks</div><div>Ranjan</div><div><br></div><div><div><div><br></div><div><br><table width="543" border="0" cellpadding="0" cellspacing="0"><tbody><tr><td><table width="543" border="0" cellpadding="0" cellspacing="0"><tbody><tr><td colspan="3"><img src="http://www.cisco.com/web/europe/images/email/signature/est2014/logo_08.png?ct=1408129135253" width="110" height="73"></td></tr><tr><td valign="top" align="left" nowrap style="padding-left:24px;padding-bottom:0px"><p style="font-family:Arial,Helvetica,sans-serif;font-size:11px;color:rgb(102,102,102)"><strong>Ranjan Jain</strong><br><a href="http://ARCHITECT.IT" target="_blank">ARCHITECT.IT</a><br>Information Technology<br><a href="javascript:_e(%7B%7D,&#39;cvml&#39;,&#39;ranjain@cisco.com&#39;);" style="color:rgb(102,102,102);text-decoration:none" target="_blank">ranjain@cisco.com</a><br>Phone: <strong><a href="tel:%2B1%20408%20853%204396" value="+14088534396" target="_blank">+1 408 853 4396</a></strong><br>Mobile: <strong><a href="tel:%2B1%20408%20627%209538" value="+14086279538" target="_blank">+1 408 627 9538</a></strong><br></p></td><td valign="top" width="50%" style="padding-left:20px;padding-bottom:10px;padding-top:15px"><p style="font-family:Arial,Helvetica,sans-serif;font-size:11px;color:rgb(102,102,102)"><strong>Cisco Systems, Inc.</strong><br>400 East Tasman Drive<br>San Jose<br>California<br>95134<br>United States<br><a href="http://www.cisco.com/" style="color:rgb(102,102,102);text-decoration:none" target="_blank">Cisco.com</a><br></p></td></tr><tr><td colspan="3"></td></tr></tbody></table><table width="400" border="0" cellpadding="0" cellspacing="0"><tbody><tr><td style="font-family:Arial,Helvetica,sans-serif;font-size:10px;padding:5px 20px 0px 24px;color:rgb(0,153,0)"><img src="http://www.cisco.com/assets/swa/img/thinkbeforeyouprint.gif" alt=""> Think before you print.</td></tr><tr><td style="font-family:Arial,Helvetica,sans-serif;font-size:10px;color:rgb(153,153,153);padding:7px 20px 6px 24px"><p>This email may contain confidential and privileged material for the sole use of the intended recipient.
