METHOD AND SYSTEM FOR PROVIDING ANONYMIZED DATA FROM A DATABASE

摘要

The invention relates to a method for providing an anonymized value for a data element stored with an original value in a database (11) of a database system (10), wherein the method comprises the following steps: (i) producing a supplementary data element for the data element stored in the database (11); (ii) determining the anonymized value of the data element from the original value on the basis of a mapping rule for ascertaining anonymized values that is stored in the database system (10), and storing the anonymized value in the supplementary data element; and (iii) linking the supplementary data element to the data element such that, based on the reception of an access command relating to the data element from a user connected to the database system, the supplementary data element is read and the anonymized value contained therein is transmitted to the user. In addition, the invention relates to a system that is suitable for performing the method and to a computer program.
