Abstract
A method is provided for securing a transaction made by bank card, the transaction involving a remote provision, by a user, of data existing in a bank card in his possession. The method includes: obtaining data existing in the bank card to be used, called textual data; obtaining at least one portion of the textual data in the form of an audio data stream, called a sound sample, resulting from reading the data existing in the bank card to be used; computing a current voice signature from said sound sample; comparing said current voice signature with a reference voice signature pre-recorded and associated with the textual data of the bank card; and when the reference voice signature differs from the current voice signature by a value greater than the first value defined by a predetermined parameter, for rejecting the transaction.
