Patent ID: 7110578

Claim:
A document processing electronic device comprising: a fingerprint information storing unit for storing information on fingerprints, which stores user identification information allocated to each of a plurality of users and information on a plurality of fingerprints related to the user identification information so that the fingerprint information storing unit stores a plurality of different fingerprints corresponding to a plurality of different fingers of a given user, wherein the plurality of different fingerprints of the given user are stored in correspondence to a plurality of different corresponding functions of the document processing electronic device; a fingerprint reader for reading a fingerprint; a use determining unit for determining permission/denial of use by comparing fingerprint information read by the fingerprint reader with fingerprint information stored in the fingerprint information storing unit; and a function use determining unit for determining permission/denial of use of a function by comparing fingerprint information read by the fingerprint reader with fingerprint information stored in the fingerprint information storing unit in correspondence to each function so that for the given user access to a first function of the document processing electronic device requires a substantial match of input fingerprint information with stored fingerprint information of a first finger of the user, and access to a different second function of the document processing electronic device requires a substantial match of input fingerprint information with stored fingerprint information of a second finger of the user.
