Method and system for processing natural characteristics like e.g. fingerprint, by means of a portable device (8), comprising means (3a) for inputting a user's PIN code and means (3) for inputting the user's natural biometric data, e.g. fingerprint. Both input means are connected to transformation means (4) which transform the natural fingerprint under control for the PIN code into an artificial fingerprint, to be supplied to a display module (5a). The displayed artificial fingerprint can replace the user's natural fingerprint when the user has to prove his/her identify. If the artificial fingerprint might become corrupt or misused, a new artificial fingerprint can be generated by inputting again the user's unchangeable natural fingerprint and together with a new PIN code. |
