JPS63313288A - Personal identification method for ic card and its ic card - Google Patents

Abstract

PURPOSE:To surely identify a person by storing an owner's bioplasma pattern in an IC card and checking coincidence with a user's pattern. CONSTITUTION:A detecting area display line 2 for indicating a finger pressure position is written on the upper surface of the IC card on the gripping part side. A person identifying pattern 3 is written in a memory of the IC card by a cipher. A pattern detecting device 4 for detecting the plasma of a finger depressed on the display line 2 is built in the IC card correspondingly to the display line 2. Bioplasma emitted from the finger in a high-frequency magnetic field and indicating a specific pattern for the person is detected by a CCD in the device 4 and collated with the person identifying pattern 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an IC card identification method and the IC card that can be used in the field of financial, medical 10 card, and other various identification fields.

[Prior Art] In recent years, IC cards have come to be used in various fields due to their high security characteristics, as they can encrypt passwords and passwords so that they cannot be easily read.

However, although the password for identifying the person cannot be easily read because it is compatible with the old striped card, this is only true as long as the person carries the IC card and the password is not known to others. Therefore, if the IC card is handed over to another person and the other person is familiar with the password, there is a problem that the security will be broken.

For this reason, from the perspective of biometrics, the physical characteristics of a person are stored in an IC card to identify whether or not the user who brings the IC card is the true owner. It's here. This includes personal identification methods based on fingerprints, palm prints, voice prints, retinas, signatures, etc.

These personal identification methods can further enhance security by comparing the physical characteristics of the IC card owner with those of the person himself/herself.

However, since these biometric personal identification systems identify the person regardless of whether the person is alive or dead, the following problems remain.

That is, in a method based on fingerprint or palm print verification, there is a risk of mistaken identification due to the mold. Also, from this,
There is a serious problem in that the owner of an IC card adopting this method is constantly at risk of having his or her fingers or hands cut off by robbery or the like.

In the case of a method based on voiceprint verification, there is a risk of mistaken identification due to restoration of the tape recording.

In addition, although methods based on retinal blood vessel pattern matching are currently considered to have relatively high security, computers cannot even recognize whether the eye is alive or dead, so it is difficult to identify the person using retinal photographs, models, etc. There is a risk of misidentification.

Furthermore, in the case of verification based on how the signature is written, for example, °
It is questionable whether it is possible to detect the reproduction movement of a teaching robot that makes the same signature as the teaching robot.

[Purpose of the Invention] In view of the conventional problems as described above, the present invention further pursues the biometric viewpoint, and provides an IC card personal identification system that has higher security and can reliably identify the user. An object of the present invention is to provide a method and an IC card thereof.

[Summary of the Invention] The present invention, which achieves the above object, uses athermal light (hereinafter referred to as
Considering that the pattern of this (called bioplasma) is unique to the living organism in question, a personal identification pattern is stored in the IC card in advance, and this and the pattern detected from the user are stored in the IC card in advance. The feature is that the person is identified by comparing with the person.

The fact that bioplasma, which is unique to a living organism, is emitted from a living organism is explained in ``Cactus Talked J'' published by Shodensha.
He is familiar with books such as P. Tompkins, C. Bird, translated by Ken Takemura.

Bioplasma is emitted from positions corresponding to so-called acupuncture points in the human body, and can be patterned both locally and globally.

Furthermore, it is known that bioplasma is emitted only from living organisms and not from dead organisms. From this point of view, the method for detecting bioplasma bodies is
Cheating doesn't work.

Therefore, if the present invention is used to identify the person on the IC card, the difficulty of erroneously identifying the person using a mold or a severed finger can be solved, and the person can be identified reliably with high security.

[Embodiment] FIG. 1 is an external view of an embodiment of an IC card to which the present invention is applied, and FIG. 2 is an explanatory diagram showing details of a pattern detection device.

As shown in the figure, on the upper surface of the IC card 1 on the grip side,
The detection area display line 2 indicating the finger press position is turned upside down.

In the memory of the IC card 1, a personal identification pattern 3 is written in code.

Further, as shown in detail in FIG. 2, inside the IC card 1 corresponding to the detection area display line 2, there is a built-in pattern detection device 4 for detecting bioplasma on a finger pressed against the detection area display 1m2. has been done.

The pattern detection device 4 consists of a coil 5 and a CCD 6 disposed inside the coil 5. When detecting a pattern, an alternating frequency current in a radio frequency band is passed through the coil 5.

In the IC card 1 having the above configuration, the IC card 1 now has an IC card interface I/F as shown in FIG.
Suppose that it is attached to

Then, at this point, a high frequency current i is passed through the coil 5, a magnetic field is generated that passes through the finger located within the detection area display Is2, and bioplasma is generated from the finger.

This bioplasma is captured by the CCD 6, analyzed by a CPU (not shown), and its pattern is formed.

On the other hand, the personal identification pattern 3 storage section stores in advance a pattern to be matched with the detected pattern.

Therefore, the CPtJ compares the detected pattern with the identification pattern 3, and if both patterns match, the IC card 1 and the IC card interface
Enables communication between F and the connected terminal.

Here, the detected pattern is detected only from living fingers, and since the personal identification pattern is unique to the person, identification of the person can be ensured.

Personal identification pattern 3 is a pattern showing the distribution of light emitting points, a spatial pattern of athermal light emitted from each light emitting point, a pattern that combines both, and other local wave number decomposition or Fourier decomposition light. The pattern may be a single pattern or a pattern of spectrum change due to modulation of an external magnetic field, or a combination thereof.

In the above embodiments, the pattern detection device is provided inside the IC card 1, but since it is not directly related to security, it may be provided on the interface side.

Further, in the above embodiment, the pattern of bioplasma emitted from the finger was compared, but other parts such as the palm of the hand or the face may be used.

The actual configuration of the security system is mixed with and used in conjunction with conventional means such as secret codes, depending on the level of security required.

[Effects of the Invention] As described above, in the present invention, the pattern of the owner's bioplasma stored in the IC card is compared with the detection pattern of the person (living person) who intends to use the card, so that identity verification is possible. This ensures that the security of internal information will not be compromised due to theft or the like. In addition to being applied to financial and medical IC cards, this invention can also be widely incorporated into computer systems as a means to replace the role of seals in Japan and the role of signatures in other countries. It will be like this.
