Title: ACCESS CONTROL FOR DATA OBJECTS
Abstract:
The invention relates to a method for access control for data objects (106, 108, 110, 112, 114, 116). A first authorisation hierarchy is provided (1002) that is dynamic starting from a first user through a plurality of users. The first authorisation hierarchy is produced gradually in this case by virtue of, starting from the first user, the last user respectively included in the first authorisation hierarchy personally allocating a first access right to a user who is to be newly included, so that each user comprised by the first authorisation hierarchy is allocated the first access right. The first authorisation hierarchy comprises at least two further users besides the first user. Further, an outbound second authorisation hierarchy produced by a second user is provided (1004). This second authorisation hierarchy is produced gradually by virtue of, starting from the second user, the last user respectively included in the second authorisation hierarchy personally allocating a second access right to a user who is to be newly included, so that each user comprised by the second authorisation hierarchy is allocated the second access right. The second authorisation hierarchy comprises at least one further user besides the second user. A user is granted access to one of the data objects only if the applicable user is comprised both by the first authorisation hierarchy, so that he is allocated the first access right, and by the second authorisation hierarchy, so that he is further allocated the second access right.
