Although PPML-methods stand to provide privacy protection in AI use cases, each one comes with a trade-off. Practitioners applying PPML-methods increasingly request an overview of the types and impacts of these trade-offs. To aid this gap in knowledge, this article applies design science research to collect trade-off dimensions and method impacts in an extensive literature review. It then evaluates the specific trade-offs with a focus group of experts and finally constructs an overview over PPML-methods and method combinations’ impact. The final trade-off dimensions are privacy, utility, effort, transparency, and fairness. Seven PPML-methods and their combinations are evaluated according to their impact in these dimensions, resulting in a vast collection of design knowledge and identified research gaps.  \nKeywords: Privacy Preserving Machine Learning, Trade-off, Hybrid Methods, Design Science  \n1 Introduction  \nNumerous practical domains stand to profit from the capabilities of Artificial Intelligence (AI), raising the heating efficiency in smart living [Ko23], aiding patients and physicians alike in smart health [Na21], and enhancing efficiency in smart audit [ERT23], just to name a few. While the possibilities of AI are virtually unlimited, practical implementation of AI often clashes with a necessity to secure sensitive data [TSG21] .

The field of Privacy Preserving Machine Learning (PPML) presents itself as the natural solution to this conundrum with various methods to preserve the privacy and secrecy of the sensitive data while still enabling machine learning (ML) to be performed. Unfortunately, applying PPML-methods opens up trade-off scenarios with the most prominent being a reduction in output utility [El22]. As AI permeates more and more organizations, people responsible for handling data in these organizations newly adopting AI-solutions are confronted with having to deal with PPML. To be able to efficiently harness the possibilities of PPML, practitioners would greatly benefit from knowing which dimensions of trade-offs to expect and in which way the application of single or hybrid PPML-methods will impact the balance in these dimensions before then diving","cbCaivDAPs8msXg4","https://ap.wps.com/l/cbCaivDAPs8msXg4","pdf",433978,1,15,"English","en",105,"# Abstract\n# Introduction\n# Theoretical foundation\n## PPML method categories\n## Data publishing approaches\n## Data processing approaches","[{\"question\":\"What trade-off dimensions are identified for privacy preserving machine learning?\",\"answer\":\"The paper concludes five final trade-off dimensions: privacy, utility, effort, transparency, and fairness.\"},{\"question\":\"How does the paper study PPML trade-offs and their impacts?\",\"answer\":\"It applies design science research using an extensive literature review to collect trade-off dimensions and method impacts, evaluates specific trade-offs with an expert focus group, and then builds an overview for methods and hybrid combinations.\"},{\"question\":\"What are the main PPML method categories discussed in the theoretical foundation?\",\"answer\":\"The paper divides PPML methods into three categories based on where they are applied in the ML process, including data publishing and data processing approaches.\"}]","Privacy, Utility, Effort, Transparency and Fairness -
