On Designing a Secure E-Commerce Transaction Management System – A UML Based Approach

Abstract

E-commerce gained popularity as a sophisticated transaction system for buying and selling of products and services efficiently through Internet. Due to lack of privacy and security, customers are unwilling to participate in E-commerce transaction system. To combat such inefficiency in transaction of E-commerce and to regain the customers trust an attempt is made here to design a prototype of a secure E-commerce transaction system that brings all components of the E-commerce into a common platform to offer a model of a unified integrated E-commerce system using DRM.

In the proposed system, the transaction manager generates single use token consisting information about the customer, merchant, product, and payment amount etc. and thereafter wrapped as a DRM package. The advantages of using such token are, after a single use the token will expire, which minimizes the possible loss in the transaction, also, as the token wrapped as a DRM package, therefore only the intended user and the specified application software can open the DRM package using special key. The application, thereafter, will take care of the rights imposed on the ‘token’ and expires itself after the single use.

To design the model of the proposed system we have tried to use Unified Modeling Language (UML), which allows developing a very flexible model that facilitates maintainability, reusability, portability and other Object Oriented software engineering features inherent in the E-commerce transaction system.
