Reputation systems in identity trust

(Jean-Luc Dorel)

Reputation system

Social contract, trust and identity management

The digital trust the 2 factor authentication. The complex of mechanisms Faking the personality in video conference is not really difficult, it has been proofed in research case from the German gov. Wikipedia is a self-managed system and it is working.

Jean-Luc: Facial expression and voice can be forged in very near future. So the most reliable trust anchor will be become unreliable. New mechanisms need to be positioned.

Peter: Document verification via video conference is not a reliable option any more. In a study by the German government it was possible to inject false identity documents in real time, overcoming mitigating measures like flashing and changing colours.

Jean-Luc: In most reputation system the authors are on the same level. Authors should have some kind of qualification.

Leif: Wikipedia is opposing this. … It is working in areas where meritocracy is working. It will not work in very controversial cases. Jean-Luc: Fake news are another problem, particularly hate speech, where anonymity is a problem to execute rights.

What sort of reputation layer could help us to build a better relationship for building a business?

Thomas: Should the government qualify the sort of news published?

Jean-Luc: We do not want a ministry of truth. But could filters include the reputation of authors?

Ivan: Reputation system does not scale. They need to start with a local domain with experts, and it can grow from this

Leif: Trust does not scale, it is always local.

Intermediaries always exist, or will be created, because RPs want to be simple.

The bubble of trust, you need to have common standards, policy is always local and it is the basic trust is there.
