A level of trust, it may be peer-generated or be determined by the service provider. Biased towards recent actions, it is an indication of a regular customer acting as expected at a predetermined registration strength or level of trust. This is usually only applicable within one organisation, or in a "community of interest" such as a group of government agencies or in "user-centric" identity management. A good example is how a user earns 'karma' at slashdot.org. Similar to Reputation or Character, it may be based on the recommendations of others whose opinions may have a trust value to the relying party, but it should be limited to within a given context. Social networking is a similar term. The results can be manipulated and even purchased, e.g. on My Space. Also see Trust, and the Federation "invitation" approach.
