Technical application embodiment of fingerprint recognition
The recognition technology of fingerprint can be applied to a lot of respects through several kinds of methods. These texts replace each computer password of application program typical embodiment most by using fingerprint and verifying in whom above recommend already. Can imagine if all systems on the computer and application program can use fingerprint to prove, it will be very convenient and safe that people use the computer, users are no longer disagreeable essential security is checked, and the services after sale of IT developer will lighten much more. Global Sign On software that IBM has already succeeded in developing and employed extensively passes and defines the only password, or use fingerprint, can advance freely in company's whole network. Combine the recognition technology of fingerprint with IC card; it is one of the most promising directions at present. This technology stores the fingerprint of the host of the card on the IC card, and install the recognition system of fingerprint additional in reading the card plane of IC card, when reading the card machine and reading the information on the card, read the fingerprint of entering the person who holds card together, through can confirm real host nipping it of person of Carlos held than fingerprint with fingerprint of person of card held in card, thus carry on the next trade. The IC card of fingerprint can be in order to widely apply to a lot of trades, for example replace current ATM card, make and defend spurious document, visa or passport, socialized medicine card, membership card, borrower's card etc. ATM Teller-Stella installs the fingerprint recognition function additional and already begins to use in U.S.A. at present. Holder can cancel password, prevent old man and child memory difficulty of password from or still keep the password, similar to time of the password according to fingerprint in operation.
In recent years, send the internet of information automatically, brings people's convenience and interests in recent years, in course of increasing fast, but has proced a lot of questions, especially in information safety. No matter the information of the group or indivial, all fear to convey in the network extending in all direction and diminish the thing of the rights and interests. Because the characteristic data of fingerprint can be transmitted and proved in the computer network through the E-mail or other transmission methods, through the recognition technology of fingerprint, have designated persons only to visit relevant information limitedly, can improve the security of online information greatly, so, including the online bank, online trade, conct of business of a series of networks of e-commerce, there is security guarantee. It is worthwhile to exactly carry on the fund by internet; they are implementing the project taking recognition technology of fingerprint as basic guarantee security at present, in order to strengthen the security of the trade.
In the hospital, the recognition technology of fingerprint can verify patient's identity; manage in for example blood transfusion. The recognition technology of fingerprint facilitates verifying and seeks to rescue publically too, the medical treatment, welfare of other governments or identity of the person of the insurance premium confirm. In the application, the recognition system of fingerprint will replace or supplement a lot of a large number of systems of using photo and ID.
In a word, as a lot of fingerprint recognition procts have already been developed and proced, the application of the recognition technology of fingerprint has already begun to enter the civil market, and develop swift and violent; it is believed that the popularization and application of this technology has been already within sight.
It is a future focus that fingerprint recognition and NFC technology combine.
As social development and instry being ripe, the center of a lot of fields of market of semiconctor is all turned from the infrastructure / office end to user's end; it is the same that the visit controls the market. The focus of controlling the market of visit is no longer traditional entrance guard, attendance, building talk backing, but round application such as consumer's carry-on mobile phone, notebook computer, mobile memory procts, intellectual ID card, electronic bank card, electronic passport. In the new development tide of this share, the living beings discern it is that two keys drive technology with NFC/RFID 。
As social development and instry being ripe, the center of a lot of fields of market of semiconctor is all turned from the infrastructure / office end to user's end; it is the same that the visit controls the market. The focus of controlling the market of visit is no longer traditional entrance guard, attendance, building talk backing, but round application such as consumer's carry-on mobile phone, notebook computer, mobile memory procts, intellectual ID card, electronic bank card, electronic passport. In the new development tide of this share, the living beings discern it is that two keys drive technology with NFC/RFID 。 The notebook computer employs and lights the market of portable fingerprint recognition 。 PC, mobile phone and move memory various electronic proct, become we routine and a portion that live a life already, we use a large amount of them to store and convey important enterprises and personal information, may involve indivial privacy, account No. information and company's business secreted, become more and more urgent to protect the security of the information. The commonly used method shortcoming of limiting apparatus, application and access of file by setting up the password is obvious the past, may have several dozen various electronic procts and account number passwords each person, should remember they often make people drained, biological recognition technology is to utilize human body's biological characteristic to carry on identity authentication, it is very simple and convenient and safe to use, as progress and cost of technology are reced, their use is more and more general, the most typical one is the fingerprint recognition 。 In 2007 the global living beings will discern instry's income will reach 3 billion dollars, used for visiting the fingerprint recognition that is controlled and accounting for 25.3% 。 Design the manager to introce, it is out of date that the operation principle of the slipping type fingerprint transcer slips on the finger with simulation circuit of limited company of core micro technology, utilize a simple linear array of transcer unit to gather fingerprint information, compared with traditional fingerprint transcer, its advantage is that the area is small, cost and low power dissipation, especially suitable for portable application. The slipping type fingerprint transcer appeared in about 2003-2004, improved and began to enter the notebook computer / mobile phone in a large amount in 2005-2006, the amount put into circulation will increase in 2007 。 And desktop begin, pay close attention to fingerprint recognition too, Tsing Hua Tong Fang whom core release a little new to exceed, raise serial PC whether their introce fingerprint recognition beginning of PC hand in hand will it be June 2007, more fingerprint recognition desktops, notebook computer procts will put out in the future 。 And early to pay close attention to mobile memory core of market little to turn to weight PC market even mainly, it is a main supplier of desk-top PC at present, the notebook computer which adopts its transcer of fingerprint begins the goods too. The core introces CMOS slipping type transcer SW6888 of fingerprint recognition littly at the end of 2004, the main advantage is that low power dissipation and dependability are high 。 It nearly needs 50 yuan to increase the fingerprint recognition function at present, in order to promote these low-cost application, it is half the new schemes of an existing scheme that the little plan of core will put out the cost next year. Flash, save application by hard disk and fingerprint to fingerprint, core little respectively with comparable to Plass push away the intact scheme jointly with core Nation microelectronics, these two back controller manufacturers, 。 NFC pays and fingerprint recognition by mails " Border is known " Application of mobile phone ： Unless last market for PC, prospect even more undoubtedly mobile phone market, at present core the little and mobile phone design company cooperation’s positive of several. Xiong CongQing also reveals, the core will put out the improvement edition of SW6888 littlie within the year, it remains a common chip, but because require to the back processor pace that will rece, will be suitable for the mobile phone. He explains, SW6888 pace of gathering data is very quick, catch the signal fast, but shortcomings takes up back processors resources more, gather the data rate in fingerprint of ability automatic regulation and control that the new chip will follow the back processor. He emphasizes: "Though other supplier can rece, gather data rate too, we whether first can make sure self-adaptation variable datum lead manufacturer 。” In fact, fingerprint recognition and two items of technology of paying by mails are being employed in the mobile phone “the border of constant change is known”, and promote each other. Atmel employ director BenoitMakowka to say: "Because of NFC technology, we see, control identity and Mobile employ the chance combined together. This is similar to moving the bank, through NFC technology, you can imagine some to visit the application that is controlled to store in (U) safely In SIM card 。” Introce, the market of global fingerprint mobile phone is mainly in the Japan and Korea S. at present, since putting out in 2005, has already formed the proction of certain scale, Han Fei is often common that main driving force is paid by mails in Japan, people are used to buying film, subway and public transit ticketed. with the mobile phone, and once involve paying by mails, need stricter identity authentication, the advantage of fingerprint recognition displays 。 It is exactly this reason; there is no active demand to fingerprint recognition on the market of Chinese mobile phone. Though hit the electric communication (CECT) Wait for a few several local mobile phone manufacturers to introce the fingerprint mobile phone this year, but still seem fragmentary. With its corresponding another side, Nokia takes China Mobile by hand and pays the experiment the NFC cell-phone in Xiamen this year, but at present NFC cell-phone mainly or Nokia and Motorola,etc. manufacturers overseas push away, the local mobile phone manufacturer of China has not really begun to research and develop yet at present, still at technology and follow stage 。 NFC chip and technology lead the supplier NXP global intelligence to discern Division's executive vice president and concurrently general manager MarcdeJong introces, NFC commercial mobile phone list, indicate, already NFC technology integration technological challenge to get Mobile solve already, the more important thing is how to drive the whole ecosystem, so NXP, with close cooperation such as mobile phone manufacturer, bank, moving the operator and service provider, make the whole instry's chain operation stand up. Xiong CongQing with little core shows too, because of involving legislating, such links as financial settlement and identity discern, it is at home might take by on the some time still not to pay mobile phone, core the little in and cooperative partner prepare technology 。 Besides NFC cell-phone, application in all kinds of intelligent cards such as intellectual ID card, electronic bank card, electronic passport of NFC/RFID technology is like a raging fire too. Makowka of Atmel points out, it is the popularizing of an electronic ID card that the future focus is applied, this is a challenge too, because various countries and all parts will make one's own norm, but there is a very strong compatible demand in a larger geographical range, such as Europe. Perhaps this kind of application will slowly take off too, because the government needs checking for the application, and it is difficult to distribute the decision of the budget for the application 。
