It seems that Identity is a hot topic nowadays. For example, there are two identity conferences this year that might be of interest:



*         Digital Identity Summit: https://digitalidentitysummit.com/

*         Know Identity - Defragmented Identity Conference : https://oneworldidentity.com/dc-conference-know-identity-2017/?gclid=CMmotYXIlNMCFYS3wAodpTkHhA



Few years ago Microsoft had the Geneva claim based access platform, where services and applications are accessed based on the claims provided by the user.

Well...



https://en.wikipedia.org/wiki/Digital_identity

  ISO/IEC 24760-1 defines identity as "set of attributes related to an entity"



So lets say GRIDS stores for an entity one or more identifier entries. Each identifier

entry has data like locators associated as well as some authenticator like a cert owned

by the entity.



Entity connects to grids, "asserts its identity" by a cryptographic proof of ownership

operation for the authenticator (eg: cert) and then it can change the data, eg: locators

associated with the identifier entry of the entity.



In this example, i guess (identifier, authenticator) is one identity of the the entity.

Maybe someone wants to spend 118 CHF on that ISO standard to get the IDEAS terminology

in compliance with it ? ;-))



How many disagreement points do i score ?



Cheers
