摘要： Biometric data relating to a biological part are processed by obtaining, on the one hand, a first set of transformed biometric data (f(B1)) by applying at least one irreversible transformation to a first set of biometric data (B1), and, on the other hand, a second set of transformed biometric data (f(B2)) by applying said transformation to a second set of biometric data (B2). Thereafter, a decision is made as to whether the second biometric data set corresponds to the first biometric data set on the basis of a comparison between the first transformed biometric data set and the second transformed biometric data set, said comparison being performed at the bit level of a digital representation of said first and second transformed biometric data sets as a function of an error corrector code word.

摘要： A cryptographic calculation is carried out in an electronic component according to a specific cryptographic algorithm including at least one specified non-linear operation on blocks of data of k bits, k being a whole number of more than 2. Several blocks of masked intermediate data of j bits are generated from an initial block of data of k bits, j being a whole number that is smaller than k. Then a non-linear operation S is applied to at least one of the masked intermediate data blocks of j bits with the aid of a substitution table with 2 inputs producing a modified data block of j bits. The modified data block of j bits and at least some of the masked intermediate data blocks of j bits are combined to form a result block of k bits corresponding to the initial data block of k bits by means of a transformation including the specified non linear operation.

摘要： A method includes transmitting a first digital channel (X0) from a reader to a marker, receiving a second digital channel (Y0) corresponding to the first digital channel and to errors introduced by a noisy channel, introducing artificial errors into at least one of the first or second digital channels, carrying out an advantage distillation phase in such a way that a new first digital channel (X1) is determined for the reader. A new second digital channel (Y1) is determined for the marker such that the advantage is taken with respect to a possible passive attacker. In an information reconciliation phase, an error-correcting protocol is applied to the new first (X2) and new second (Y2) digital channel, and in carrying out a secrecy amplification phase, a hash function (G) is applied to the new first (X2*) and the new second (Y2*) digital channel.

摘要： Additional information regarding a fingerprint is estimated, with a given level of confidence, on the basis of characteristics of a set of minutiae corresponding to this print. Local descriptors are determined around some at least of the minutiae, so that they comprise, in relation to zones comprising additional information estimated with the given confidence level, values calculated on the basis of said information and, in relation to zones not comprising such information, erasures. The local descriptors determined are quantized according to a given number of integer values, a value being reserved for erasures. The quantized local descriptors are coded with the aid of an error-tolerant coding algorithm associated with a decoding algorithm devised to take account of errors and erasures. And a pseudo-identity is determined on the basis of some at least of the coded quantized local descriptors.
