Abstract

Personalisation-privacy paradox Personal data stores systematic literature review privacy paradox decentralization decentralised

The personalisation–privacy paradox captures the tension between using personal data for personalised services and respecting individuals’ privacy. This study adopts a holistic research framework to clarify the paradox’s core challenges, evaluate existing solutions, and examining a user-centric approach. First, a systematic literature review across information systems, marketing, and management reveals that current solutions often prioritise privacy, framing the paradox as a “dilemma” rather than a persistent tension between privacy and personalisation. Personal Data Stores (PDS) are identified as a technical solution to managing the paradox: decentralising data control, enabling users to determine precisely what they share and thereby reducing privacy risks; and unlocking richer personalisation by integrating multiple data sources and facilitating transparent data markets.  A survey empirically tests user perception of PDS, showing that individuals who understand the approach believe it mitigates their privacy concerns without compromising service customisation. These findings suggest that PDS offer a dual response, rather compromise, allowing firms to manage the paradox.
