One starting point when consolidating or harmonizing the
civil register is to look for the unmistakable element with the greatest reliability which enables an individual to be identified.
In many countries where names, addresses and dates of birth are standardized and reliable, this basis can be used as an identification reference system.
Biometry is, in such situations, a simple attribute that makes it possible to secure the link between physical person and data.
In countries where semantic standardization work on citizens' names is not entirely finalized, we might reasonably assume that biometric recognition will most likely be the common element with the greatest reliability. This will as the basis of identification.
On this point, it should be noted that it is generally considered that although identification data is shared between the citizen concerned and the government bodies, the civil register data is however generally viewed as representing Private Data. Such data belongs to the citizen personally, who entrusts it to the State in the role of notary and archiver, and then presents it when requesting an official document issued by the State. The civil register, in this sense, may incorporate an individual's biometric data, as soon as this can be considered, barring accidents, as being permanently valid and reliable.
In the case of biometric databases compiled previously, the issuing of residence permits, new electronic identity cards and biometric passports will be an opportunity to update biometric data and check the doubly unmistakable relationship of fingerprints to name held on civil register.
