It is not (only) about privacy: How multi-party computation redefines control, trust, and risk in data sharing

Firms are often reluctant to share data because of mistrust, concerns over control, and other risks. Multi-party computation (MPC) is a new technique to compute meaningful insights without having to transfer data. This paper investigates if MPC affects known antecedents for data sharing decisions: control, trust, and risks. Through 23...

Making private GPS data available to policy makers: Investigating the feasibility of multi-party computation for smart mobility

With recent advances in performance and complexity, multi-party computation, a privacy-preserving technology which allows for joint processing of hidden input data, has lately been found to be applicable in a number of use cases. Despite existing implementations for secure data aggregation, substantial adoptions of the technology remain limited...

Privacy Threats and Cryptographic Solutions to Genome Data Processing

The genome is the blueprint of life and has a detailed genotype and phenotype description of any organism. This in itself attributes sensitivity to genetic data, be it in the biological or electronic format. The possibility of sequencing the genome has opened doors to further probing of the data in its electronic form. Post sequencing of the...

Business model implications of privacy-preserving technologies in data marketplaces: The case of multi-party computation

Privacy-preserving technologies could allow data marketplaces to deliver technical assurances to companies on data privacy and control. However, how such technologies change the business model of data marketplaces is not fully understood. This paper aims to bridge this gap by focusing on multi-party computation (MPC) as a cryptographic...

Preserving privacy through cryptography in online behavioural advertising

Online advertising is a multi-billion dollar industry, forming one of the primary sources of income for many publishers that offer free web content. Online Behavioural Advertising (OBA), the practice of showing advertisements based on individual users' web browsing behaviours, greatly improves the expected effectiveness of advertisements, and is...
