Anonymity Certification Technique of a Smart Card base for Personal Information Protection
2012
Regarding the official authentication method which is a strong encrypt method for financial transactions, there has recently been a concern for the problem of storage. As a solution for such problems, this study provides the anonymous authentication method based on the smart card used for such a purpose by utilizing the pseudo ID replacing the user`s personal data. Such an anonymous authentication method makes it possible to prevent any inside leakage, intermediary attack, limited re-transmission attack, service-denying attack, directional safety attack and secret inspector attack in regard to the user`s personal data. As a result, there would be no concern for the leakage of any personal data. In comparative analysis, after executing the comparison and analysis process through the experiment for the authentication process by using the previously-used smart card, the new one has shown about 10% a high level of efficiency for the encrypt and decrypt process together with excellent features in terms of flexibility in regard to the user`s anonymity and tracking ability.
