The solution provides better service privacy than centralized service provision. By better
service privacy we assume that it is not necessary for the customer to disclose private data
and preferences to a service provider in order to get a proper service (as it is assumed in the
case of centralized service provision). The customer's preferences can be encapsulated into
the personal agent who may run in the user's (protected and trusted) computational
environment and they can be non-available for non-authorized parties. Of course, we can't
completely eliminate the risk of disclosing the private information, however, the proposed
solution tries to reduce such a risk.
The solution may give better flexibility in describing preferences than centralized service
provision. There are no requirements to keep a unified definition of attributes presenting
customer's preferences.
The solution provides better scalability than centralized service provision. Analysis and
information processing can be asynchronous, decentralized, and distributed.
The above-mentioned properties give better personalization of services and take into account the
restrictions of mobile devices when generating output to the customers.
A PLATFORM FOR MOBILE E-COMMERCE SERVICES SUPPORT
Taking into account the conceptual solution presented in the previous section, we propose a
general platform for generating systems supporting mobile e-commerce services (see Figure 5).
