Hierarchical anonymization algorithms against background knowledge attack in data releasing
作者:
Highlights:
• We define a privacy model based on k-anonymity and one of its strong refinements to prevent the background knowledge attack.
• We propose two hierarchical anonymization algorithm to satisfy our privacy model.
• Our algorithms outperform the state-of the art anonymization algorithm in terms of utility and privacy.
• We extend an information loss measure to capture data inaccuracies caused by not-fitted records in any equivalence class.
