dc.description.abstract | Computational models of trust have been proposed for use in
ubicomp environments for deciding whether to allow customers to
pay with an e-purse or not. In order to build trust in a customer, a
means to link transactions using the same e-purse is required.
Roughly, trust is a result of knowledge. As the number of
transactions increases, the resulting increase in knowledge about
the user of the e-purse threatens privacy due to global profiling.
We present a scheme (and its prototype) that mitigates this loss of
privacy without forbidding the use of trust for smoothing payment
by giving the opportunity to the user to divide trust (i.e.
transactions) according to context (e.g. location, user?s current
activity or subset of shops). | en |
