Mining Roles from Event Logs While Preserving Privacy
TL;DR: It is shown that the problem cannot be solved by naive approaches like encrypting data, and an anonymized person can still be identified based on a few well-chosen events and a decomposition method and a collection of techniques that preserve the privacy of the individuals are introduced.
Journal ArticleDOI
Group-based privacy preservation techniques for process mining
TL;DR: This paper provides formal definitions of attack models and introduces an effective group-based privacy preservation technique for process mining that covers the main perspectives of process mining including control-flow, time, case, and organizational perspectives.
Book ChapterDOI
TLKC-Privacy Model for Process Mining.
TL;DR: The TLKC-privacy model for process mining is introduced that provides privacy guarantees in terms of group-based anonymization and extends and customizes the LKC- Privacy model presented to deal with high-dimensional, sparse, and sequential trajectory data.
Journal ArticleDOI
