Abstract

Providing access to media data shared by multiple users. A predefined edge weight is assigned to each edge of a linked data structure based on a dependency category of the edge. A first access rating value is assigned to each node. A rating residue value is calculated as the difference between the two first access rating values of the nodes connected by each edge. The data structure is traversed from a seed node, and for each edge traversed, calculating a second access rating value using an edge weight value and the first access rating value. Repeating until the rating residue values meet a predefined convergence criterion. The nodes having access rating values meeting a predefined data removal criterion are selected from the nodes of the linked data structure. The data entities corresponding to the selected nodes are then removed.
