Abstract

The invention concerns a method and a data processing system to protect an electronic data object from unauthorized access. Via a method, a) in a first step, an electronic data object identifier is generated dependent on the content of the data object, b) in a further step, an access right is determined dependent on the data object identifier, and c) in a last step, an access to the data object is allowed dependent of the access right. The data processing system comprises a data processing device and an access control module. Via the access control module, an electronic data object identifier can be generated dependent on the content of a data object, and an access right can be determined dependent on the data object identifier. The access right can comprises standard rights such as “Read” or “Write” and an “Execute” right to execute specific functionalities.
