Kenya’s High Court ruled Thursday that a recent amendment requiring citizens to register for a national biometric digital identification system overreached on some counts, such as allowing for links to DNA or GPS records, and failed to guarantee sufficient inclusion of Kenyan residents. 

The ID system, called the National Integrated Identity Management System (NIIMS), was a homegrown answer to India’s pioneering Aadhaar system, which two years ago faced its own Indian Supreme Court ruling that upheld some components while modifying others. 

More than half of African countries are developing some form of biometric or digital national ID in response to major international calls to establish legal identification for the almost 1 billion people who now lack it. But this ID boom, also taking place outside Africa, often gets ahead of data protection laws, as occurred in Kenya.
