Abstract: The study is an empirical inquiry on data sharing and national security in Nigeria, an interrogation of the practice of multi-agency collation of similar data. The objectives of the study are to establish the relationship between multiple biometric capturing and accuracy of biometric information in Nigeria and to ascertain the effect of inter-agency data sharing on crime prevention, investigation and control in Nigeria.in view of the specific objectives of the study, two research questions and hypotheses were formulated and tested for the study. Data for the study was obtained through primary and secondary sources. With a total population of 355 respondents, a sample of 188 was obtained using Taro Yamani Formula. Data obtained from the respondents was presented in table and analyzed using frequency counts and mean scores and the hypotheses were tested using Pearson correlation at 0.05 level of significance. Findings from the study revealed that there is no significant positive relationship between multiple biometric capturing and accuracy of biometric information in Nigeria and that inter-agency data sharing has an effect on crime prevention, investigation and control in Nigeria. On the basis of the findings, the researchers recommended, among others that the Nigerian government should set modalities in place to begin to harmonize existing data and to extend the reach and coverage of the citizens in order to create a robust database for effective policy planning, security and provision of social services.
