Filed: 2001-12-26
Abstract: <P>PROBLEM TO BE SOLVED: To realize suitable immigration control by objectively directly confirming authenticity of an emigrant himself/herself or an immigrant himself/herself.  <P>SOLUTION: In immigration control devices 1AA, 1BB, 1CC of the respective countries, the emigration processing of each emigrant and immigrant processing of each immigrant are conducted. In the emigration processing, an emigration fingerprints picking device 10 stores the emigrant information such as name showing the emigrant and the fingerprints information showing the fingerprints of the emigrant in a control information storage device 11. In the immigration processing, an immigration fingerprints collating device 13 refers the fingerprints information of the emigrant who is to be the same person as the concerned immigrant to the immigration control device of another country through a communication network. The immigration control device of the referred party retrieves the control information storage device 11 for the fingerprints information, and returns the same. The immigration fingerprints collating device 13 collates the fingerprints of the returned fingerprints information with the fingerprints of the immigrant, thereby discriminating whether the concerned immigrant is the same as the former emigrant or not.  <P>COPYRIGHT: (C)2003,JPO
