MyData

MyData is a personal data marketplace platform launched in 2019 by SNPLab that enables individuals to monetize their de-identified personal data while allowing businesses to access anonymized consumer insights. The platform implements Self-Sovereign Identity principles through its did:snplab method and uses on-device storage to keep personal data exclusively on users' mobile devices.

The platform's core technical architecture combines several key components:

• An encrypted Personal Data Store (PDS) that uses NIST-recommended cipher suites
• W3C DID-compliant decentralized identifiers generated independently on users' phones
• Blockchain-based transaction logging using Hyperledger Fabric for immutable records
• AI-based targeting that enables businesses to reach specific audiences while maintaining user anonymity
• Data anonymization processes that remove personally identifiable information

The project has gained notable traction in South Korea, partnering with organizations like Korea Gallup and receiving support through government initiatives including the 2022 Inter-ministerial Technology Commercialization Relay Project. A key implementation is the ESA-ON public service app developed for Seoul Municipality that provides one-click administrative services. The platform aims to balance commercial data utilization with privacy protection by giving users control over their data while enabling businesses to access valuable consumer insights through anonymized channels.
