By verification, do you mean before issuing an ID or after that during its use for gaining access to facilities.
Before issuing the id. All problems originate due to malcious registration. Which is why the cop goes to visit the place of residence, verify with the neighbours and check for criminal records. This verification itself depends on the fact that the user gas not used an alias before for criminal activities or now during registration. So the initial verification process is fraught with holes.
Both are anyway possible. However we can have 2 levels of verification based on the security requirements, one fast for daily use, like latest photo, finger print... and one slow and detailed, like dna, blood test for criminal investigation purposes.
The point of using DNA is that it is uniqe and is directly related to up and down stream. Thus traceability is automatic. There is no need for any detailed initial verification even during registration. This is because of the above characteristic of relatedness and ability to match raw dna data. For daily use just entering the id will automatically provide a relationship tree (like any other id system). A more detailed check wil re run a dna match with up and down stream members with the stored dna data (not possible with any other id system). If the person gives wrong info it will be apparent immediately. If the person is a criminal suspect, a resampling of dna will provide the detailed check neccessary. We are assuming that re / sampling is a simple process (which it isnt at the moment but will be in one to two years given the rate of innovation in biosensor tech).
Instead of relating, can't a dna pattern be an independent id like a finger print?
It is an independent pattern but the advantage is that it is related. So u cant claim to be me cause re samplin your dna will show that my parents dna are completely different from yours. In the case of siblings trying to masquerade things get more complicated - particularly with those who have no offspring. Incase of identical twins it will require sherlock holmes. But inspite of the corner cases DNA will outstrip by orders of magnitude any other id system. While initial costs will be high, recurring costs will fall to near zero due to it's relationship ability.
