Abstract
The security of data elements which represent an industrial process, which are manipulated by users on a data processing system and in which the industrial process includes a series of industrial process steps, are controlled by permitting groups of users to access predetermined data elements based on the industrial process step at which the industrial process is currently active. A user is prevented from accessing the requested element if the industrial process is not at an industrial process step corresponding to one of the industrial process steps for which the user has authority to access the data element. Thus, access to data is prevented based on the status of the data, in addition to the type of data. When selected database elements are associated with one of many locations, access is also denied to a user based on the location. Security access based on status and location may be provided in response to a change in the current industrial process step. Access authority to the data elements is changed compared to the access authority at the immediately preceding industrial process step based on mappings in one or more tables. Improved security of data elements which represent an industrial process is thereby provided.
