Description
Technical field
The IC-card that the present invention relates to IC-card identification system and used by this system, particularly relate to by setting up corresponding with the identifying information stored in IC chip based on the characteristic information fixing the random pattern had, thus the card identification system that can easily and reliably differentiate the true and false of the judgement IC-card of the IC-card be forged and the IC-card used within the system.
Background technology
In recent years, in order to improve the security of credit card, money transaction card etc., the IC-card assembling the IC chip possessing microprocessor, storer etc. is promptly popularized.These IC-cards store such as to card or block the relevant authentication information of user in IC chip, when card is by use, by checking stored authentication information and the cross-check information be kept in outer computer, judge the true and false of this card.
But, because be not easy to distort the data stored in IC chip, so in recent years, exist and take out IC chip itself to make the illegal activities of new forgery card from card.That is, carry out following this illegal activities: such as from card, take out IC chip, the real IC chip taken out is transplanted to the 1st and forges in card, in the former card having taken out IC chip, assemble the IC chip of adulterant, make the 2nd thus and forge card.Then delivering to Ka Fahangqingqiuzhechu by assembling the 2nd forgery card forging IC chip, making card issue requester confirm accepting of card by phone, online terminal etc., thus obtaining the usage license of the 1st forgery card assembling real IC chip.
As for taking out IC chip and the forgery preventing techniques that stops of the use of the forgery card produced from card to this, such as described in JP Laid-Open 10-255013 publication (patent documentation 1), TOHKEMY 2005-301554 publication (patent documentation 2), TOHKEMY 2011-128960 publication (patent documentation 3), propose following method: once take out IC chip from card, then the antenna circuit be connected with IC chip etc. are destroyed thus the use of IC-card itself becomes impossible.
But, IC-card as described above forges preventing techniques, and there are the following problems: can not be effective for making the use of the card having taken out IC chip itself become, but for stoping the use of the new forgery card produced by taken out real IC chip being transplanted to other and blocking to be invalid.
In addition, forge preventing techniques as other IC-cards, there will be a known such as TOHKEMY 2001-126046 publication (patent documentation 4), TOHKEMY 2001-266088 publication (patent documentation 5), TOHKEMY 2005-1267 publication (patent documentation 6) and the technology described in TOHKEMY 2009-187086 publication (patent documentation 7).
IC-card described in patent documentation 4 ~ 7 forges preventing techniques, utilize special inks printing technology, special decorative pattern printing technology, eletric watermark technology, the special information recording technique such as strong magnetic material paper tinsel utilizes technology, tape utilizes technology, the information read area that have recorded the authentication information be manually made is set in card base material.Then, when judging the true and false of IC-card, use the identifying information stored the authentication information and IC-card read from information read area simultaneously, by judging whether authentication information mates with the incidence relation of identifying information with the authentication information be stored in advance in storage medium with the incidence relation of identifying information, can judge the true and false of card.
But, IC-card described in patent documentation 1 ~ 7 forges the problem that preventing techniques exists following internal: because the authentication information used with the identifying information of card is also the information be manually made simultaneously, so once the cross-check information of card is understood, even then special information recording technique, also can utilize it to copy the information read area recording authentication information fairly simplely.
In addition, these IC-cards forge preventing techniques, because special inks printing technology, special decorative pattern printing technology, eletric watermark technology must be utilized, the special information recording technique such as strong magnetic material paper tinsel utilizes technology, tape utilizes technology, so there is card and use the formation of the system of card to become complicated, card and system become very expensive problem.And, forge in preventing techniques at the IC-card described in patent documentation 1 ~ 7, because the information read area of certain area must be occupied in the setting of card base material, so bringing various restriction when designing card, existing and freely can not design the such problem of IC-card.
And, a kind of identification system is described in TOHKEMY 2007-272541 publication (patent documentation 8), by in the database of server etc., registration and id information establish the identifying information of the card origin associated in advance, thus the identifying information detected from card and the identifying information read from server etc. corresponding to id information are checked, the true and false of card can be judged thus.
But, in the identification system described in patent documentation 8, because the information utilized in order to the true and false judging card is only the identifying information of card origin, and in the card having taken out IC chip, remain the identifying information of card origin, so existence can not prevent doing new forgery by the blocking of having taken out IC chip effectively block such problem.
