Identity and TrustEnabling Layers of the Future Communication Landscape
Piotr Cofta, Chief Researcher, BT
We essay a difficult task; but there is no merit save in difficult tasks.

The more elaborate our means of communication, the less we communicate.
Joseph Priestley 1733-1804
No 'more' but 'better' communication
Create the network with people in mind
Understand how people communicate
Prepare technical design guidelines
Communication is autopoietic
Communication exists to sustain communication
• Self-inflicted problem of unbound growth
• Improvement through communication shortcuts

Identity and Trust
Identity and trust are constructed to combat the growing complexity of
communication
• Identity and trust are both social constructs
• They exist because we communicate
• They are side-effects of communication
• They serve as communication shortcuts
Identity
It is not an address, name, post code, card, PIN or fingerprint
Your identity is my perception of your persistent interacting 'whole'
"I construct your identity"
IP
Identity as a communication shortcut
• Identity encapsulates past, allowing for consolidation (I know him, so...)
• Identity defines communication endpoint (Mom, are you there?)
• Identity guarantees targeted delivery of signals across the society
(Could you please tell your friend...)
• Identity removes the need to start from scratch (As we have agreed...)
Identity Protocol
Future 'Identity Protocol' layer is about active construction of identities
• Self-determination and autonomy (incl. privacy)
• Social relevance (incl. communities)
• Flexibility, openness and interoperability
IP
Trust
It is neither virtue nor weakness, neither an emotional tweak nor a calculated move. It is a necessity.
Trust is an expectation of predictable future behaviours of an intentional entity
Trust does not imply benevolence, only adherence to type
TCP
Trust as a communication shortcut
• Trust encapsulates future, by setting default expectations
(I cannot imagine Bob doing this...)
• Trust is a type selector, simplifying interpretation
(Alice is a doctor, she will get it right..)
• Trust decreases semantic gap in understanding
(We are so alike, no need to explain everything...)
• Trust increases meaning while decreasing volume
(That goes without saying...)
Trust & Control Protocol
Future 'Trust & Control Protocol' is about assessing justified trust
• No trust -> enforcement without understanding
• Total trust -> understanding without communication
• Justified trust -> trust that is matching trustworthiness
