Title: Portable wireless fingerprinter indentification system and method

Description:
TECHNICAL FIELD 
     The present invention relates to a portable wireless fingerprint recognition system, in which user&#39;s four-digit identification number is transmitted to a main system by using a portable terminal having a fingerprint recognition element and a keypad via electric waves such as radio frequencies or Bluetooth (short-distance wireless communications standard), or light such as infrared rays, and user&#39;s fingerprint registered in a database of the main system is transmitted to the portable terminal via electric waves such as radio frequencies or Bluetooth, or light such as infrared rays, so that the received user&#39;s fingerprint is recognized and verified by the fingerprint recognition part of the portable terminal, resulting in the direct control of the main system by the portable terminal, and a method for the wireless fingerprint recognition. 
     BACKGROUND ART 
     In general, a portable terminal using fingerprints may be used in every security system in which fingerprints are required. Therefore, a user carries only one terminal and uses the same in various different security systems. Also, such security systems in which fingerprints are required may be directly and simultaneously controlled by a plurality of users by means of their portable terminals each having the fingerprint recognition element. 
     Previously, the fingerprint recognition system is connected to the main system by wire, so that users should directly and inconveniently touch a fingerprint recognition part of the main system with their fingers all the time. Further, even though a plurality of users have to carry out the fingerprint recognition simultaneously, they should carry out the fingerprint recognition in turn, which is annoying time-consuming procedure, so that they cannot pass a security section simultaneously. 
     Furthermore, there is limitation in the fingerprint recognition if the fingerprint recognition part is located at a polluted place or at a difficult place for users direct touch.

     MODE FOR THE INVENTION 
     Hereafter, an embodiment of a portable wireless fingerprint recognition system which carries out the present invention will be described with reference to the drawings. 
       FIG. 1  is a schematic view showing the entire structure of a portable wireless fingerprint recognition system according to a preferred embodiment of the present invention. Referring to  FIG. 1 , the portable wireless fingerprint recognition system according to a preferred embodiment of the present invention includes a portable terminal  2  having a main control part  4  which carries out a series of operation according to a key input of a user  1  and a fingerprint recognition part  5 , and a main system  3  which receives a radio signal from the portable terminal  2 , searches fingerprint data of the user from a fingerprint database  6 , and transmits the searched fingerprint data to the portable terminal  2 , wherein the main system  3  is driven to operate as verification is carried out according to a radio signal that the fingerprint data verifies the user&#39;s identification in the portable terminal  2 . 
       FIG. 2  is a view showing a state that a security system is driven to operate by the portable wireless fingerprint recognition system of the present invention, which shows the portable terminal  2  carried and manipulated by the user  1  and the main system  3  mounted to a door of a security area to be driven by the manipulation of the portable terminal  2  so as to carry out verification. 
       FIG. 3  is view showing an exterior structure of the portable terminal  2  according to the present invention. Referring to  FIG. 3 , the portable terminal  2  includes an LED lamp  8  to blink when a signal is sent to the main system  3  from a main body  7  of the portable terminal or a signal is received from the main system  3 , a keypad  9  displaying numerals from 0 to 9 and symbols of ‘*’ and ‘#’, and a fingerprint recognition part  5  for recognizing and verifying a fingerprint received from the main system  3 . Reference symbol  10  which is not explained is a hole for inserting a key and the like. 
       FIG. 4  is a flowchart for explaining a main verification system according to the present invention 
     Now, the operation of the portable wireless fingerprint recognition system according to the present invention will be described in more detail. 
     The verification system of the portable terminal  2  and the main system  3  is initiated when the user  1  presses a key *’ of the keypad  9  on the portable terminal  2  in a certain security section, wherein user&#39;s identification number is transmitted to the main system  3  as the user presses pre-registered four-digit identification number of his own and a key ‘#’ in sequence. 
     At this time, the transmitting and receiving of data between the portable terminal  2  and the main system  3  are carried out by electric waves such as radio frequencies or Bluetooth, or light such as infrared rays. 
     The main system  3 , which receives the identification number of the user  1 , searches fingerprint data registered in the fingerprint database  6  and transmits the user&#39;s fingerprint data to the portable terminal  2  of the user  1  after encoding and compressing the searched user&#39;s fingerprint data. 
     Also, the transmitting and receiving of data between the portable terminal  2  and the main system  3  are carried out by electric waves such as radio frequencies or Bluetooth, or light such as infrared rays. 
     The portable terminal  2  decodes and decompresses the fingerprint data received from the portable terminal  2  to prepare the main control part  4  in a standby state, and the fingerprint recognition part  5  transmits a recognized fingerprint to the main control part  4  as the user  1  touches the fingerprint recognition part  5  with a finger for fingerprint recognition, so that the main control part  4  kept in the standby state compares the fingerprint received from the main system  3  with the recognized fingerprint. 
     If the user is verified as a result of the fingerprint comparison, a radio signal is transmitted from the portable terminal  2  to the main system  3  automatically under the control of the main control part  4 , so that the verification system of the main system  3  is driven to operate. 
     If an error message is generated three times or more in the process of user verification, if a verification setting section is deviated, or if time elapses more than one minutes, the verification procedure may be re-started from a system initiating step or from a user identification registering step. 
     According to the present invention, the portable terminal  2  and the main system  3  constitute a single wireless fingerprint recognition system, so that a user may simply carry out the verification of the main system  3  wirelessly at a remote place by using the portable terminal  2  without approaching the main system  3  for driving the verification system. 
     INDUSTRIAL APPLICABILITY 
     According to the present invention, a plurality of users may pass a gateway security system simultaneously by carrying out fingerprint recognition at remote places by means of the portable terminals instead of directly touching the fingerprint recognition part of a main security system with their fingers. Further, such fingerprint recognition may be conveniently carried out at any places where the security system is required by simply carrying their portable terminals, thereby increasing the security effect. Furthermore, user&#39;s fingerprint registered in the main system may be verified not by the main system but by the portable terminal directly, so that the main security system may be under control of the portable terminal. 
     It should further be apparent to those skilled in the art that various changes in form and detail of the invention as shown and described above may be made. 
     It is intended that such changes be included within the spirit and scope of the claims appended hereto.
