Abstract
The invention relates to a method for authenticating an external authorizing datum by a portable object, such as a memory card. The authorizing datum (C1) entered into an apparatus (2) is enciphered with a predetermined datum (E) to yield a message (M) which is transmitted to a portable object (1). The object (1) deciphers the message (M), taking into account a reference authorizing datum (C1), in order to retrieve a datum (E'), which must be coherent with the datum (E). The invention applies in particular to the recognition of the carrier code of the owner of a credit card.
