Biometric data is frequently used to uniquely identify an individual. However, recent studies show that biometric data acquired for identification purposes when processed reveals sensitive information about data subjects rendering them vulnerable and infringing on their privacy rights. It is therefore argued that data protection framework in Nigeria is blatantly insufficient to effectively protect the vulnerabilities brought on data subjects by reason of the processing of their data. The perspective is founded on a careful examination of Nigeria’s current legal framework vis- a-vis the privacy, security, human rights, ethics and socio-cultural implications associated with the processing of biometric data of data subjects. Through deliberate comparison with Biometric Information Act of the United States, this paper identifies challenges which impedes the protection of biometric data and proffers solutions.
