A low-cost secure schemes for authentications and access control with the use of multiple public IC cards

in the present day, the requirements of security in modern information systems are increasing significantly. Among secure requirements, the personal identification plays an important role for authentications and access control. However, traditional id/password pairs could be disabled by modern hacking techniques and social engineering easily. In order to provide stronger access control for organizations, personal identification tokens are widely used in the present day. With the features, unique and unduplicable, personal identification tokens could be used to provide strong reliability for user authentication. However, the cost of issuing a propriety identification tokens for each employee could be expensive. The high cost may block the managers to adopt token-based secure schemes, and then reduce the secure levels of organizations. In this paper, a low-cost secure scheme is proposed. This scheme is based on widely used public cards which employees would have by themselves. The combination of multiple public cards can be used to build strong secure protections by weight-calculating algorithms, and then provide adaptable secure levels for each user. Thus organizations could have strong secure protections without additional cost.
