Definitions
- the invention relates to a method for unblocking access to devices, data and other devices to which access can be achieved by entering a personal identification number, the so-called PIN or a password, according to the preamble of claim 1.
- a PIN has so few digits, four are usual that they can be memorized. This also applies to a password.
- the PIN usually actually consists of single digits, while a password can consist of letters or a combination of letters and numbers.
- the locked user is given the opportunity to unlock the device himself by means of an extended PIN or by means of an extended password.
- the function of the normal PIN is controlled by the Users themselves restored by entering the extended PIN.
- the expression PIN will also be used for the expression password to keep the presentation easier. The invention thus has the considerable advantage of a much simpler procedure for unlocking the PIN or the password.
- the extended PIN provided according to the invention is advantageously equipped with significantly more digits.
- the user can therefore usually not memorize them.
- Both PINs are made known to the individual user; he himself must ensure that they are kept securely. This applies in particular to the extended PIN, which is only used in extreme cases when the simple PIN can no longer be used, either because it has been lost or because the specified number of failed attempts has been reached.
- the extended PIN After an expedient design of the extended PIN, it has a specific relationship to the simple PIN. For example, the last four digits of the extended PIN can be the same as the four-digit simple PIN.
- An example of such a mass application can be a medical chip card for diabetics, which is protected with a four-digit PIN.
- the patient received this PIN in a so-called PIN letter, ie in a closed envelope, as is also the case with the PIN for the Euro check cards.
- This envelope also contains the extended PIN, for example with ten digits.
- This PIN letter is kept in a safe place and the patient memorizes the four-digit PIN. With this four-digit PIN, the patient is allowed access to the chip card.
- the card will block after five failed attempts, for example.
- the patient would have to go to an authorized authority to have the card unlocked again.
- This authority for example a health insurance company, has the authority to unlock the cards. To do this, the identity of the cardholder must be carefully checked. On the other hand, the instance, the health insurance company, cannot read the medical data on the card. This ensures that it is the rightful owner of the card to be unlocked and that data protection is not violated.
- the present invention opens up the possibility of regenerating the card without having to visit the authorized entity, such as the health insurance company in the present example.
- the authorized entity such as the health insurance company in the present example.
- Either the patient himself has a personal computer with a chip card reader at home, where he, as a diabetic, enters his self-monitoring data on the chip card at home, or he goes to the family doctor and regenerates his card himself using the extended PIN that has now been selected. Only when the number of attempts to unlock using the extended PIN has failed will the card be finally locked and can only be officially unlocked by the authorized authority.
