1. The Contracting States : DE, GB, FR A method of processing information on an optically readable recording track (13) of a portable carrier (1) such as a card, consisting in order to safeguard the confidentiality of the information to be recorded on the track ; - in using a magnetically writable magneto-optical recording track (13) and lan external magnetic writing device (23), - in transferring this information to the interior of an electronic memory (12B) of the portable carrier, - in encoding this information in the interior of the portable carrier (1) by means of processing circuits (11) and a secret encoding key prerecorded in a memory zone (12A1) which is inaccessible from the outside of the portable carrier (11), - in transferring the encoded information to the external writing device (23) in order to write them magnetically on the magneto-optical recording track (13) of the portable carrier (1) For Contracting States : IT, NL, SE A method of processing information on an optically-readable recording track (13) of a portable carrier (1) such as a card, coupled to an external write/read device (23), characterized in that it consists in order to safeguard the confidentiality of the information to be recorded on the track ; - in transferring this information to the interior of an electronic memory (12B) of the portable carrier (1), - in encoding this information within of the portable carrier (1) by means of processing circuits (11) and a secret encoding key prerecorded in a memory zone (12A1) which is inaccessible from the outside of the portable carrier (1), - in transferring the encoded information to the external write/read device (23) in order to write it on the optically readable recording track (13) of the portable carrier (1).
