Description
SPECIFICATION
An individual recognition system
FIELD OF THE INVENTION
The present invention relates to a system for recognizing an individual with the use of a higher level recognition method.
BACKGROUND OF THE INVENTION
Recently, a card having a magnetic stripe is widely used in a system for recognizing a particular individual (The recognition card is abbreviated as M/S card). For example, in a card to be used for a deposit drawing apparatus installed in a bank (hereinafter referred to as "deposit card") there are stored a code for recognizing the genuineness of the card and a recitation code for judging as to whether a card possessor is a right card possessor registered in the card or not.Accordingly, the deposit drawing aoparatus is designed to read out the genuineness code in the card thereby to judge as to whether the card is genuine or not, to instruct the card possessor to input a recitation code from the key board, and to judge as to whether the card possessor is a right card possessor or not based upon the result of comparison of the input recitation code with the recitation code registered in the card. In this system, a numeral or symbol sequence which is relatively easy to memorize is appropriate for use as a recitation code.
The above described method is widely used because the truth or falsehood of the card possessor is relatively easily judged.
However, this system has a few disadvantages described in the following:
The first one arises caused by that the recitation code must be memorized by a card possessor by himself. That is, the safety against a crime is inevitably lowered because a card possessor is likely to use a simple recitation code so as not to occur a misunderstanding or a lapse of the recitation code.
However, when a too complicated code exceeding the memory of a human being such as a certificate of one's seal impression is used instead of the recitation code, it is very troublesome or difficult to bring the recitation code with himself, and furthermore there arises an anxiety of burglary. This means that it results in no improvement in the safety.
SUMMARY OF THE INVENTION
The present invention is directed to solve the problems pointed out above, and has for its object to provide an individual recognition system capable of unnecessitating the memorization of the recitation code and of enhancing the safety with no anxiety of forgery.
Other objects and advantages of the present invention will become apparent from the detailed description given hereinafter; it should be understood, however, that the detailed description and specific embodiment are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
According to the present invention, there is provided an individual recognition system for judging as to whether a card possessor is a right card possessor or not, comprising: a card storing a fingerprint of the right card possessor; a card reader to which the card is inserted, and which is intended to read the fingerprint of the card possessor; and a judging means for judging as to whether a card possessor is a right card possessor or not based upon the result of comparison of the fingerprint of the card possessor taken in by the card reader with the fingerprint registered in the card, which judging means is provided in the card or the card reader.

DETAILED DESCRIPTION OF THE PREFERRED
EMBODIMENTS
The present invention provides an individual recognition system in which a fingerprint is used instead of a recitation code. It is easily understood that a fingerprint is most appropriate to be used as a recitation code because it is inherent to an individual.
In order to explain the present invention in detail, reference will be particulaly made to
Figure 1: In the following example an IC card is used as a card storing the fingerprint. An IC card includes semiconductor elements such as a memory IC or a CPU in a card, and has a larger memory capacity by several columns than the M/S card. Furthermore, it involves desired operational functions such as characteristics extraction and comparison.
Figure 1 is a block diagram showing an individual recognition system as an embodiment of the present invention. In Figure 1, the reference numeral 20 designates an IC card storing the fingerprint of the card possessor as an individual information. That is, the characteristics of the depth and interval of the fingerprint are registered in the card 20. The reference numeral 30 designates a card reader intended to read out an information stored in the IC card 20 which is inserted thereinto. In the card reader 30, the reference numeral 30a designates a CCD camera or an ITV camera for reading the fingerprint. The numeral 30b designates a multi-value coding section intended to execute a multi-value coding to the information read by the camera 30a.The numeral 30c designates a characteristics extraction section intended to extract the characteristics such as the depth and the interval of the fingerprint stored in the IC card 20 from the output of the multi-value coding section 30b. The numeral 30d designates a comparison section intended to compare the output of the characteristics extraction section 30c and the information read out from the IC card 20.
As apparent from the above the characteristics extraction section 30c and the comparison section 30d constitute a judging means 30e for judging the truth or falsehood of the card possessor, that is, whether the possessor of the card 20 is a right possessor or not.
As apparent from the above, the card reader 30 has the following functions for judging the truth or falsehood of the card possessor:
(1) An interface function to read a fingerprint code stored in the IC card (not shown).
(2) A function to read a fingerprint of a particular finger of a card possessor (this is accomplished by the CCD camera or ITV camera 30a and the multi-value coding section 30b).
(3) A function to compare the two finger
prints to judge whether they are the same or
not (this is accomplished by the characteristics
extraction section 30c and the comparison
section 30d).
Such functions are easily realized by using
known methods.
The operation of the registration of the fin
gerprint information into the IC card 20 is de
scribed in the following:
The fingerprint of a particular finger is
picked up by a camera as a picture, and the
picture information of the fingerprint 1 is con
verted into an electric signal by a light-electri
city conversion. Or a fingerprint may be di
rectly picked up by a CCD camera or an ITV
camera 10. A characteristics extration is exe
cuted to this fingerprint by a known data
compressing method, and it is multi-value
coded with the use of a gradation code of 6 to 8 bits for multi-value coding. Thus, the fin
gerprint pattern is converted into an electric
signal, and the pattern code is stored in the
IC card 20.Although it is required a memory
capacity of about 64 K bite for storing a raw fingerprint pattern, the required memory capacity can be reduced to about 1 K bite when only the characteristics such as the depth and interval of the fingerprint are stored. Then, the code number of the card or the like can be stored by using the remaining memory capacity. The double rectangle in Figure 2 is used to indicate that the content of the block is registered in the IC card 20. The same also applies to Figure 4.
The device is operated as follows:
When a card possessor inserts the IC card 20 into the card reader 30, and places a particular finger on a window for taxing in a fingerprint, the fingerprint of the card possessor (which is an information for-comparison) is picked up. The picked up signal is coded into a gradation code signal by the multi-value coding section 30b, and a characteristics extraction is executed to this signal by the characteristics extraction section 30c to be output to the comparison section 30d. In the comparison section 30d the fingerprint code read out from the IC card 20 and the extracted characteristics information are compared with each other, and it is judged as to whether the possessor of the card is a right card possessor or not.
In this embodiment under such a construction, a fingerprint is used as a recitation code, whereby the necessity of memorizing a recitation code comprising such as a numeral sequence is removed, resulting in easeness and conveniency at a practical use. Furthermore, a forgery of the card is unabled, resulting in a high safety.
Figure 3 shows another embodiment of the present invention wherein the characteristics extraction function and the comparison function are involved in the IC card 20. In Figure 3 the same numerals designate the same elements as those shown in Figure 1. The reference numeral 20d designates a judging means comprising a characteristic extraction section 20a and a comparison section 20b, and this judging means 20d is provided in the IC card 20. The card reader 30 comprises only a CCD camera or ITV camera 30a and a multi-value coding section 30b. Herein, the numeral 20c designates a memory storing the fingerprint code.
In this embodiment, not only the fingerprint
1 but also a characteristics extraction program 20a' and a comparison program 20b' are registered in the IC card 20 as shown in Figure 4, and the respective functions of the characteristics extraction section 20a and the comparison section 20b in the IC card 20 are realized by the respective programs 20a' and 20b'. The both programs 20a' and 20b' are stored with the use of the memory capacity other than that for the fingerprint code.
The operation of this embodiment is almost the same as that of the first embodiment. In addition thereto, there is no necessity of providing the characteristics extraction function and the comparison function at the card
reader 30, thereby making the card reader 30
miniaturized and low cost thereby to realize a
oortable fingerprint comparison system.
In the illustrated embodiment a fingerprint in
planer configuration is used as a fingerprint to
oe registered, but a fingerprint in stereoscopic
configuration can be used.
A fingerprint in stereoscopic configuration to
be registered is obtained by extending a real
stereoscopic configuration of tne fingerprint
into a planer configuration by rotating the fin
ger. A fingerprint in stereoscopic configuration
is registered into the IC card 20 in such a
manner that the fingerprint obtained by the
rotating method is directly picked up by a
CCD or ITV camera, and a characteristics ex
traction is executed thereto by a known data
compressing method with the use of a grada
tion code of 6 to 8 bits for multi-value cod
ing. Thus, the characteristics of the fingerprint
is converted into an electric signal, and this
fingerprint code is stored in the memory
(ROM) in the IC card 20.It is generally re
quired a memory capacity of about 64 K bite
for a raw fingerprint, but it can be reduced up
to about 1 K bite when only the character
istics such as the depth and interval of the
fingerprint are stored. Then, the code number
of the card or the like can be stored with the
use of the remaining memory capacity. The
information of rotation speed of the finger at
the taking in of the fingerprint is also regis
tered with the fingerprint information in the IC
card 20.
This stereoscopic configuration fingerprint
registered in the IC card 20 is used as a
whole or a part thereof when it is difficult to
judge the truth or falsehood of the card pos
sessor only on the basis of the result of com
parison of the data D1 in planer configuration
and the data dl in planer configuration as the
output of the characteristics extration section
30c. In greater detail, when it is suspicious
about the truthhood of the card possessor as
described above a fingerprint in stereoscopic
configuration of the card possessor is taken in
together with the rotation speed information
with the use of the above described rotation
method, and the extracted characteristics
coded into two-values is subjected to a char
acteristics extraction.And then, this data d2
(refer to Figure 3(c)) is compared with the
registered data D2 in the IC card 20.
In this embodiment utilizing a stereoscopic
configuration fingerprint it is more likely pos
sible to orevent a forgerious input of a finger
print than the first embodiment utilizing a
planer configuration fingerprint. This enhances
the safety against crimes to a great extent.
Furthermore, the rotation speed information of
the finger at the taking in of the fingerprint
can be used in the comparison when there is
a suspicion, thereby enabling to obtain a right
judgement even when a stereoscopic configuration fingerprint of a right card possessor is input under an intimidation by other person.
As a result, it is enhanced the preciseness in the judgement about the truthhood of the card possessor.
In the above illustrated embodiments IC cards are used as a card, but a laser card capable of random access of reading and writing by a laser can be used.
As described above, according to the present invention, a fingerprint in planer or stereoscopic configuration is used instead of a recitation code, thereby resolving the disadvantages of the recitation method. Furthermore, a forgery of a card and a forgerious input of the fingerprint are unabled, thereby realizing a quite safety system.
