Abstract:
This research is intended to solve a major problem in implementing Sudan e-government,
which represents how electronic payments system will be implemented and prepared to
be imbedded as part of the whole system.
The payments system is now centrally managed by Federal Ministry of Finance (MOF).
All payments to the government are done through Form_15 which is uniquely designed
for any state or national organization. MOF managed the issuing and distribution of this
form but does not control how and when will be used.
In this research moving from the paper-based payment to electronic is key challenge;
considering the special characteristics of Sudan in terms of rules, regulations and
implementation environment.
This research divides process into three parts; each part includes definition of its job, start
time, end time, actors and location.
The main process is located in the center (MOF) and it is responsible for generating and
distributing unique electronic identifiers for every client (states and national
organizations). This identifier is uniquely defining payment through the Sudan and
known as a payment number. The center is also responsible for tracing usage of those
numbers and performing financial auditing
The second part of the process which resides in the client side is responsible for getting
payment numbers from the center and managing the usage of those numbers.
The third part simulated a traditional teller which issues and cancels payments
considering all financial rules and our design restrictions such as payment can only be
done when an unused payment number is available in the database and the user has rights
to use it.
This system will be implemented over WAN, so the security is a major challenge of
implementation. We propose a Database Management System that supports a security
VE-government Central Payment Control System
tool as a third party such as Kerberos which provide single-sign on, data integrity and
authorization.
The studies designs and models the data exchange method between related clients such as
commercial registry, tax chamber and its sub-offices using messaging service with
buffering technique to tolerate data loss due unreliability of connection.
