| Summary: | Credit Cards have become one of the most successful elements in the business world. The low security of online purchasing systems using credit cards presents countless opportunities for fraud. The current online purchasing system using credit cards has some security drawbacks; therefore, its security needs to be enhanced with taking into account the cost, time and friendly using issues. An integrated authentication model of online purchasing using credit cards is proposed. A security enhancement is suggested in this work by implementing a prototype which integrates the current credit card authentication system with the fingerprint authentication. Moreover, it complements the new techniques for validating and transmitting the fingerprint template whereby, the customer submits his/her credit card information through the internet together with a file containing the fingerprint template and a validation code. This technique makes the model more secure, at the same time; it makes credit card fraud more difficult. Credit card information, FP-TAC (Fingerprint Transaction Authorization Code) and fingerprint template are the main components of the prototype. The FP-TAC is able to handle the usage of the scanned fingerprint template only once and prevents the submission of the old and expired templates. In addition, The BAC (Biometric and Authorization Code) file is presented in this work to increase the fingerprint template's security; it has its own structure in terms of storing the FP-TAC and fingerprint template which is unknown for the attacker and known only for the matching program. This technique ensures that only the matching program has the ability of loading the BAC file and extracting the FP-TAC and fingerprint template. The model is fast and reliable in extracting and matching the FP-TAC, at the same time, it validates the received fingerprint template efficiently. Fingerprint verification provides the desired processing time and accuracy rate in terms of capturing and matching the fingerprint templates. The average processing time consumed by the model to match the data is 2.47 seconds while the overall accuracy rate is 99.48% with 0.52% error rate. Combining both credit card information and fingerprint authentication leads to a user friendly, stronger and more secure online purchasing system while the cost and processing time remains within reasonable limits. Evaluating the performance of the prototype shows very good potential that encourages the continuance of the investigations in this field. |
