Method and apparatus for checking access authorization for a system
First Claim
1. A method for checking access authorization for a system, which comprises:
- providing a system having a portion that is at least difficult for a user to access;
storing an access authorization code in the portion of the system that is at least difficult for the user to access;
in the system, storing a modified code that is different from the access authorization code;
subsequent to storing the modified code, detecting biological features of a user;
comparing the detected biological features with predetermined features that have been stored in the system; and
if the detected biological features match the predetermined features that have been stored, then;
using a computation rule to calculate a calculated code from the modified code, transmitting the calculated code to the portion of the system that is at least difficult for the user to access, and in the portion of the system that is at least difficult for the user to access, comparing the calculated code with the access authorization code that has been stored.

Abstract
The present invention relates to a method for checking access authorization for a system. A modified code is stored in the system in advance. An access authorization code is stored in a part of the system which users cannot access or have difficulty accessing. The modified code is different from the access code. Biological features of a user are detected and are compared with features that are stored in the system. If the features match, a computation rule is used to calculate a code from the modified code, the calculated code is transmitted to the part of the system which users cannot access, and there, it is checked using the stored access authorization code. The invention also relates to an apparatus for checking access authorization for a system.

13. An apparatus for checking access authorization for a system, comprising:
-
a first memory unit for storing an access authorization code, said first memory unit configured to be difficult to access by a user;
a second memory unit, for storing a modified code that is different than the access authorization code, said second memory unit for storing biological features;
an input unit for entering and detecting biological features of a user;
a first comparator unit connected to said input unit for receiving the detected biological features and connected to said second memory unit for receiving the stored biological features, said first comparator unit configured for comparing the detected biological features with the stored biological features and for outputting an access authorization signal if the detected biological features match the stored biological features;
a second comparator unit connected to said first memory unit; and
a processor connected to said first comparator unit, said second memory unit, and said second comparator unit, said processor configured for calculating a code from the modified code using a computation rule based on the access authorization signal from said first comparator unit, said processor configured for transmitting the calculated code to said second comparator unit;
said second comparator unit configured for comparing the calculated code transmitted by said processor with the access authorization code stored in said first memory unit and, if there is a match, granting access authorization. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
