Individuation Privacy Preservation Oriented to Sensitive Values
Jia Jiong · Dianzi xuebao · 2010
Existing anonymity models for privacy preservation cannot implement individuation preservation oriented to sensitive values.To solve the problem,the paper proposes a complete (α,k)-anonymity model which can implement individuation privacy preservation for sensitive values by setting the frequency constraints on each sensitive value in every equivalence class.The paper also proposes a (α,k)-clustering algorithm to implement all kinds of (α,k)-anonymity models.Experimental results show that the complete (α,k)-anonymity model provides better privacy preservation than other (α,k)-anonymity models with the similar information loss and execution time.
