A special group has now been created to examine the methods that police use with respect to sensitive information on individuals.
Elliason hopes the group will not uncover further evidence of secret databases, although he could not rule out the possibility of further findings.
The database, kept by the Skåne police in southern Sweden, showed family ties between individuals and was deemed to be illegal by the Swedish Commission on Security and Integrity Protection.
The chancellor of justice awarded damages of SEK 5,000 to the individuals on the register. The state has been taken to court over the matter and the organisation Civil Rights Defenders have said they are prepared to go to the European Court of Justice.
