(1) The registration authority may verify, by automated means, whether the data on a named individual which it receives by way of an automated request match the data stored in the population register if it would be permissible to provide basic information from the population register.
(2) Where a person is unambiguously identified on the basis of the selection data in the population register and the data match the data stored in the population register, the registration authority sends confirmation thereof to the requesting person or body. Where this is not the case or a block on releasing information within the meaning of section 51 or a conditional block on releasing information within the meaning of section 52 has been entered in the population register, the requesting person or body receives notification which may not permit any conclusions to be drawn as to whether no matching data on the data subject are available or whether a block or a conditional block on releasing information has been entered.
(3) Persons relating to whom a block on releasing information has been entered are to be informed without delay of any requests made relating to them. Section 51 (3) and (5) applies accordingly.
(4) Section 10 (2) and section 40 (1), (3) and (4) apply accordingly.
