[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0025] The present invention proposes a fine-grained access control method for massive graph data based on security labels, which is a special design and access control optimization for graph data stored in key-value type. In key-value stored graph data, both nodes and edges are part of the graph data. When organizing graph data by points, such as figure 1 As shown, the point is used as the key KEY, the attribute of the point and the edge associated with the point are used as the value VALUE, and for the edge, the edge is used as the key, and the attribute of the edge is used as the value. The invention sets security labels on key-value pairs of points or edges for access control of points or edges, and sets security labe...
