Towards a Safe Realization of Privacy-Preserving Data Publishing Mechanisms
Résumé
This article addresses the issue of adapting the traditional model of Privacy-Preserving Data Publishing (PPDP) to an environment composed of a large number of tamper-resistant Secure Portable Tokens (SPTs) containing private personal data. Our model assumes that the SPTs seldom connect to a highly available but untrusted infrastructure. We illustrate the problem by studying the feasability of the simple generalization privacy mechanism to enforce k-anonymity.
