Abstract
The invention relates to a touch screen and a password-inputting method thereof, wherein the touch screen comprises a touch chip or circuit, a touch screen body and an encryption module, the touch screen body is electrically connected with the touch chip or circuit, and the encryption module is used for encrypting all or part of position coordinates; and the method includes the following steps that: the touch screen encrypts the position coordinates of a visual keyboard area, and an authorization program acquires and decrypts the encrypted position coordinates, and then recovers a password according to the mapping relation between the position coordinates and password characters. The touch screen and the password-inputting method thereof can prevent unauthorized programs from obtaining the position data of the touch screen inputting the password, consequently, the password can hardly be disclosed, and thereby the use safety of electronic payment or an electronic payment system is greatly enhanced.
Description
Technical field
The present invention relates to pay by mails, be specifically related to a kind of touch-screen and cipher-code input method thereof.
Background technology
Code keypad is the authentication input equipment in being widely used in paying by mails, uses in bank, security, shop, shopping online and mobile payment or the like transaction occasion.Wherein input represent the safety assurance of process of the password of legal identity be code keypad the basic function that must have.Also release simultaneously corresponding safety standard in the world, the how tame mechanism in E-Payment field unites the international organization-PCI(PaymentCardIndustry that has set up the formulation safety standard in 2006, payment card industry), release the safety standard of the payment devices of v2.0 version, wherein just password input, transmission safety have been done very concrete and strict requirement.A lot of products all have touch-screen, thereby can be by show touch keyboard on display screen, and prompting operation person inputs password.But the general words that directly on touch-screen, the information of touch location passed to processor that go up, because program (pseudo-program) the prompting operation person of personation removes to input password, the result has stolen the password of input plaintext by the judgement of the position data of touch-screen possibly.
Prior art is to upset with the way of the position of display button at random to do cursor position, but this way still exists by the information of resident wooden horse or other program touch locations and then obtains the leak of code characters, also brings to the user simultaneously and uses inconvenience.
Summary of the invention
The technical issues that need to address of the present invention are, how a kind of touch-screen and cipher-code input method thereof are provided, and can avoid unauthorized program to obtain the touch-screen position data of input password.
First technical matters of the present invention solves like this: make up a kind of touch-screen, comprise the touch-screen body that is used to generate electrical signal of reaction, with the touch chip or the circuit that are connected, are used for described electric signal is converted into position coordinates with it, also comprise the encrypting module that is connected, is used to encrypt all or part of position coordinates with described touch chip or circuit, this encrypting module is encrypted the touch-screen position data of input password at least.
According to touch-screen provided by the invention, described encrypting module is the microprocessor of built-in encryption algorithm, and this cryptographic algorithm includes, but are not limited to adopt the DES/3DES algorithm of standard, and DES is the abbreviation of data encryption standards (DataEncryptionStandard).
According to touch-screen provided by the invention, described encrypting module also can be built in the described touch chip, unites two into one with the touch chip.
According to touch-screen provided by the invention, it is resistance, electric capacity or infrared touch panel that described touch-screen includes, but are not limited to.
Another technical matters of the present invention solves like this: make up a kind of touch-screen cipher-code input method, by touch-screen viewed keyboard input password, utilize the touch-screen of built-in encryption module, may further comprise the steps:
Described touch-screen is encrypted the position coordinates in viewed keyboard zone;
Authoring program obtains the mapping relations of encrypting after the described position coordinates in back, the deciphering again opsition dependent coordinate and code characters and is reduced into password.
According to method provided by the invention, described viewed keyboard is a numeric keypad, and described code characters only comprises numeral.
According to method provided by the invention, described viewed keyboard is an integral keyboard, and described code characters comprises numeral, English alphabet or system definition character.
According to method provided by the invention, the position coordinates outside the viewed keyboard zone is encrypted or do not encrypted to described touch-screen, but the use of original system for convenience, the zone that is used to input password that can preferably on touch-screen, draw and subscribe, when touch coordinate falls within predetermined zone, the coordinate position value is with encrypted, and other non-password input areas then can not encrypted coordinate figure.
According to method provided by the invention, the described zone that is used to input password can be fixed, that is: all invoked code keypads regional location of living in is identical; Also can change, such as: the code keypad that at every turn calls regional location of living in may be different.
According to method provided by the invention, unauthorized program can't obtain to input the positional information of password, and the mapping relations of encrypting the described position coordinates in back and code characters can not be the relation of a code characters of all coordinate Mapping in the same area more yet, and it just is difficult to obtain code characters based on described position coordinates after encrypting like this.
According to method provided by the invention, described viewed keyboard zone also claims cryptographic zone.
Touch-screen provided by the invention and cipher-code input method thereof are avoided unauthorized program to obtain the touch-screen position data of input password, and then are made password be difficult to be revealed, and have improved the safety in utilization of E-Payment or payment devices greatly.
Description of drawings
Further the present invention is described in detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is touch-screen electricity theory diagram of the present invention;
Fig. 2 is based on the schematic flow sheet of password input in the specific embodiment of the invention of touch-screen shown in Figure 1.
Embodiment
As shown in Figure 1, touch-screen has increased the encrypting module that and touch chip or circuit is connected in the specific embodiment of the invention on the basis of existing touch-screen, and this encrypting module is encrypted the position coordinates in the visual code keypad zone on the touch-screen body at least.
As shown in Figure 2, password input flow process is built in the payment devices with touch-screen shown in Figure 1 in the specific embodiment of the invention, specifically may further comprise the steps:
The touch-screen body sensing user touch of touch-screen generates the electric signal that contains positional information;
The touch chip of touch-screen or circuit are handled electric signal and are transferred it to coordinate;
Judge whether to be positioned at the encryption zone? be to utilize the encrypting module of touch-screen to carry out the coordinate encryption, directly do not enter next step;
Coordinate after will handling by data-interface offers the side of obtaining.
In the said method flow process, described encryption zone is the visual code keypad zone of subscribing that is used to input password; The described side of obtaining is little process chip of payment devices, connects the touch chip or the circuit of described touch-screen by its data I/O (I/O) end.
The above only is preferred embodiment of the present invention, and all equalizations of being done according to claim scope of the present invention change and modify, and all should belong to the covering scope of claim of the present invention.
