Control flow structure preservation during process fragment anonymization: (Short paper)

Abstract

Existing process anonymization work does not yet support control flow anonymization. However, as the control flow is one core component of business processes and represents confidential information, this can result in an information leakage. Hence, a control flow anonymization approach is proposed. It merges multiple control flows from the same process collection to minimize the similarity between the original and the anonymized one. At the same time, the original control flow structure is preserved to foster the representativity of the anonymized flows. The approach is prototypically implemented and evaluated with 10, 987 business process models from multiple process collections.
