Embodiment Construction

[0028] A data processing system for implementing the invention is shown in FIG. 1 . The system comprises a data processing device 1 with a display 3 and a keyboard 5 via which electronic data objects can be accessed. The data objects that can be accessed are located in the application memory 9 . Access to data objects in the application memory 9 is controlled by the access control module 7 .

[0029] The access control module 7 works independently of the operating system's access control mechanisms (eg, relying on user-specific file-specific ACLs). In a preferred configuration, it is designed as an additional program layer (data access layer) and can be connected to the data bus of the data processing device 1 as a modular hardware component. However, its implementation can also take place within the data processing device 1 only on a software level. The access control module 7 controls all data accesses to the data objects it controls, such as deletion, copying, creation, ...

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.

Description

technical field [0001] The invention relates to a method for protecting electronic data objects from unauthorized access, to a data processing system implementing the method, and to a storage medium on which information for implementing the method at a data processing device is stored. Background technique [0002] The increasing use of electronic data objects requires more and more intelligent mechanisms for protecting electronic data objects from unauthorized access. In this case, a data object can be, for example, an individual file, an integrated file system or a file structure for storing or storing information. The protection of data objects is especially important in workplaces that are used by multiple people and from which confidential information can be called up. Such information occurs in, among others, medical work environments, in laboratories, research, development, etc. or work environments where demographics are performed. Basically, especially personal in...
