Abstract: Provided is a fingerprint matching method and apparatus using fingerprint minutiae and fingerprint binary images. The method includes: constructing a template fingerprint database by extracting minutiae information and a binary image of a first fingerprint image; and extracting minutiae information and a binary image of a second fingerprint image to be authenticated and performing authentication by aligning the extracted minutiae information and the binary image of the second fingerprint image with data in the template fingerprint database. Accordingly, the fingerprint matching using the fingerprint binary images is additionally performed, thereby reducing a false acceptance rate (FAR) compared to a conventional minutia-based fingerprint authentication method.

Abstract: Provided is a method and apparatus for authenticating a fingerprint by hiding minutiae, securely storing information on the fingerprint, and authenticating the information on the fingerprint in order to prevent the information on the fingerprint from being reused by an attacker who accesses the information on the fingerprint that is stored in a storage unit. The method for recognizing fingerprint by hiding minutiae of a fingerprint adds fake minutiae information to genuine minutiae information, hides fingerprint information using a polynomial, which is generated based on personal intrinsic information, and stores the fingerprint information, thereby securely protecting the fingerprint information from an external attacker, and preventing the fingerprint information accessed by the attacker from being reused since the attacker cannot know the genuine minutiae.

Abstract: Provided are a method and apparatus for securely distributing digital content. According to the method and apparatus, content is securely transmitted to users who have a right of use content regardless of the reliability of a content distributor, thereby allowing the users to efficiently use content. For example, even if an unauthorized third party changes a list of content users by deleting a user who has a right to use content from the list or adding a user who has no right to use content to the list, such an unauthorized change can be easily detected in real time, thereby securely protecting the list. Accordingly, it is possible to securely distribute and use digital content regardless of a content distributor.
