Read IPhone or iPad UUID using web application

Do you know if is possibile to get the uuid, the result of [[UIDevice currentDevice] uniqueIdentifier], using a web app ? I need to access from iphone/ipad a web page using safari (and not UIwebview under application control) and I should identify the device using its UUID.

For example I 开发者_如何学JAVAwould like to send an email Message to a user containing a link. When the receiver opens the link from its device I should autenticate him/her through UUID ?

Any suggestion ? Thanks

No this isn't possible as far as I'm aware.
