This project investigates the legal aspects of digital identities operating on a global scale, and focuses on the use of commercial genealogical DNA databanks stemming from – predominantly US-based – private companies for criminal investigations all over the world. Namely, we attend to the convergence between surveillance, forensics and direct to consumer technologies. This case is particularly salient because it ties together the rapid rise, and intensive use of biometric identifiers, the commodification of digital identities, and the use of recreational identity services in criminal investigations. The objective in unravelling this practice is to problematize digital identities, to examine how they become something else when mobilized for different purposes on a planetary scale, and what the social and legal consequences thereof are. Our research will answer three questions: What are the legal, social, and institutional environments enabling the production of identities produced through commercial DNA services? What are the legal tensions and gaps arising from the commodification of identity? What are the implications of the convergence of different, formerly geographically, legally, normatively isolated systems, uses, and practices around (digital) identities?
