Of course, that makes the task of the examiners more difficult when they have to ensure that the applicant is really the person he claims to be, verify all the documents, ensure that the birth certificate among other things is valid. If there's an electronic link, it is easier. For instance, one can verify whether the person is deceased. I wouldn't say this necessarily decreases security but however, it can increase controls and system effectiveness.
