Title: DATA ACCESS CONTROL METHOD
Abstract:
The present invention relates to a method for data access control in a security module (100), which comprises a memory (103) containing first data (105-1) and second data (105-2), the first data (105-1) and the second data (105-2) being secured by means of the same multi-modal authentication feature (101). Said method comprises the steps of: selecting (S101) a first verification method (107-1) for generating a first authentication feature or a second verification method (107-2) for generating a second authentication feature; permitting (S103) access to the first data (105-1) of the security module (100) upon verification of the first authentication feature by imaging the multi-modal authentication feature (101) onto a first authentication feature by way of a first imaging method; and permitting (S103) access to the second data (105-2) of the security module (100) upon verification of the second authentication feature by imaging the multi-modal authentication feature (101) onto a second authentication feature by way of a second imaging method.
