CPC G06F 21/6254 (2013.01) | 15 Claims |
1. A method for storing a file containing personal data, the method comprising:
obtaining a temporary anonymous identifier of a person, wherein the temporary anonymous identifier is dependent on a token of the file;
extracting from the file personal data items associated with the person;
for each personal data item, generating a locator, which allows the personal data item to be reinstated into the file, and an item-specific anonymous identifier of the person, wherein the item-specific anonymous identifier is generated by applying a predefined one-way function to a combination of the temporary anonymous identifier and an identifier of the personal data item;
storing each personal data item together with the locator and the item-specific anonymous identifier in a first memory; and
storing an anonymized version of the file without the personal data items in a second memory.
