Devices and methods are disclosed which relate to identifying ‘duplicate’ records in a database by finding similarities between records and applying a set of heuristic rules to determine a likelihood of being a duplicate record. The weighted results of the application of the heuristic rules identify possible duplicate records in the database. Embodiments of the present invention search records comprising fields of personal information. Matches are found between records and weighted according to the degree of similarity and uniqueness. By taking account of the different modes by which duplication errors typically originate in the database to which the method is applied, these heuristic rules identify a higher percentage of actual duplicate records in the database. The heuristic rules also produce a lower rate of ‘false positives’ than the methods for identifying duplicate records in databases now known in the art.
