Abstract
In a method for use in checking a person's identity, at least part of an image of a fingerprint from the person is transformed so that a representation of a frequency content in said part of the image is obtained. Based on the obtained representation of the frequency content, a frequency code is determined, which contains a predetermined number of frequency code values. A device for carrying out the method is also described.
