Fig. 11From: An anonymous entropy-based location privacy protection scheme in mobile social networksRelationship between anonymous time and k value among different algorithms in sparsely populated regions. It indicates that the anonymous time of enhanced-DLS, K-SDCA, and MOS algorithms gradually increases with the raise of k. Under the conditions of the same k value, the K-SDCA algorithm is more efficient than the enhanced-DLS and MOS algorithmsBack to article page
