摘要： The invention relates to a method of masking a plain datum b having n bits. The inventive method is characterised in that a masked datum m is produced using the following masking function: (I), wherein p is a prime number, bi is the bit at position i of plain datum b, and qi is the prime number at position i in a set of prime numbers (q1, . . . , qn). The invention also relates to a method of masking a biometric print, consisting in: determining a set of s real minutiae which are characteristic of the print; mixing and arranging the real minutiae with t false minutiae; and forming a mixed biometric datum b having n=s+t bits, such that, for any i: bi=1 if position i corresponds to a real minutia, and bi=0 if position i corresponds to a false minutia. The invention can be used to secure a security document such as a bank cheque. m = ∏ i = 1 n ⁢ ⁢ q i b i ⁢ mod ⁢ ⁢ p ( I )
摘要翻译：本发明涉及一种掩蔽具有n位的普通数据b的方法。本发明的方法的特征在于，使用以下掩蔽函数产生掩蔽的数据m：（I）其中p是素数，bi是平原数据b的位置i处的位，qi是位置处的素数我在一组素数（q1，...，qn）中。本发明还涉及一种掩蔽生物特征印刷的方法，其包括：确定作为印刷特征的一组真实细节; 混合和安排真实细节与虚假细节; 并且形成具有n = s + t位的混合生物测定数据b，使得对于任何i：bi = 1，如果位置i对应于实际细节，并且如果位置i对应于虚拟细节，则bi = 0。本发明可用于确保诸如银行支票之类的证券文件。 m =Πi = 1 n⁢q i b i mod⁢p（I）

摘要： A method and associated device for checking a biometric signature by a simple and secure calculation adapted to personal objects of the chip card type. The method is based on the storage within the object of an obscured biometric signature and an associated authentication code. A terminal capturing a fingerprint compares the fingerprint data with the obscured biometric signature transmitted by the card and transfers the result of this comparison to the chip card, which validates this result with the authentication code.
