Abstract
A fingerprint encryption scheme based on irreversible function has been designed in this paper. Since the fingerprint template includes almost the entire information of users’ fingerprints, the personal authentication can be determined only by the fingerprint features. This paper proposes an irreversible transforming function (using the improved SHA1 algorithm) to transform the original minutiae which are extracted from the thinned fingerprint image. Then, Chinese remainder theorem is used to obtain the biokey from the integration of the transformed minutiae and the private key. The result shows that the scheme has better performance on security and efficiency comparing with other irreversible function schemes.
صُمم في هذا البحث مخطط لتشفير بصمات الأصابع يعتمد على دالة غير قابلة للعكس. ونظرًا لأن قالب بصمة الإصبع يتضمن تقريبًا مجمل معلومات بصمات أصابع المستخدمين، فإن التحقق من الهوية الشخصية يمكن أن يتحدد فقط من خلال سمات بصمة الإصبع. يقترح هذا البحث دالة تحويل غير قابلة للعكس (باستخدام خوارزمية SHA1 المُحسَّنة) لتحويل النقاط الدقيقة الأصلية المستخرجة من صورة بصمة الإصبع المُرَقَّقة. ومن ثم، تُستخدم مبرهنة الباقي الصينية للحصول على المفتاح الحيوي عبر دمج النقاط الدقيقة المُحوَّلة مع المفتاح الخاص. وتُظهر النتائج أن هذا المخطط يحقق أداءً أفضل من حيث الأمان والكفاءة مقارنةً بالمخططات الأخرى القائمة على الدوال غير القابلة للعكس.
