Reputation Management

Trust

Here you can find some descriptions of trust. Depending of the trust model the authors explain some methods used for establishing trust in P2P applications. The document gives a survey of trust systems (policy based, reputation-based, social networks-based).

The authors examine the issue of managing trust in P2P systems. They focus on reputation based schemes and give also a survey of related work.

This paper presents an attribute vector calculus based approach for modeling a continuum of trust; which models the real world model of trust, as closely as possible.

There is a conflict between trust and privacy. Both depend on knowledge about an entity. They work with multiple virtual identities and link evidences to an identity.

Identity is a central element of computational trust. The lack of a central authority for all entities can be used for privacy protection.

Details for the following documents will follow.

Most 2D barcode projects are designed/used to encode URLs. See RFC 4151 and http://www.taguri.org for a way to create URI schemes (e.g. to encode a public key fingerprint) on the fly.

QR Code

  • Kurzbeschreibung: http://en.wikipedia.org/wiki/QR_Code
  • etwa 2k Daten
  • sehr verbreitet in Japan und insb. 30 Mio. japanischen Mobiltelefonen
  • leider zu patentbehaftet: "QR Code is open in the sense that the specification of QR Code is disclosed and that the patent right owned by Denso Wave is not exercised."
