Identification for Development: The Biometrics Revolution – Working Paper 315
By Alan Gelb and Julia Clark –
Formal identification is a prerequisite for development in the modern world. The inability to authenticate oneself when interacting with the state—or with private entities such as banks—inhibits access to basic rights and services, including education, formal employment, financial services, voting, social transfers, and more. Unfortunately, under documentation is pervasive in the developing world. Civil registration systems are often absent or cover only a fraction of the population. In contrast, people in rich countries are almost all well identified from birth. This “identity gap” is increasingly recognised as not only a symptom of underdevelopment but as a factor that makes development more difficult and less inclusive.
Many programs now aim to provide individuals in poor countries with more robust official identity, often in the context of the delivery of particular services. Many of these programs use digital biometric identification technology that distinguish physical or behavioural features, such as fingerprints or iris scans, to help “leapfrog” traditional paper-based identity systems. The technology cannot do everything, but recent advances enable it to be used far more accurately than previously, to provide identification (who are you?) and authentication (are you who you claim to be?). Technology costs are falling rapidly, and it is now possible to ensure unique identity in populations of at least several hundred million with little error.
