B) be used for the data of the described mensuration of check in described device or the equipment of signal;
C) be used in described device, carrying out the equipment of scrambled to importing data; Wherein
D) be to realize to the check of described determination data or signal by comparing with the reference data in the memory device that is stored in described device with these data or signal or from the characteristic of its derivation, and wherein
E) come described input data are carried out scrambled by the key within the storer that is stored in described device, and wherein
F) be equiped with a kind of equipment that is used to transmit the input data that described scrambled crosses, and wherein
G) the input data crossed of described scrambled do not contain about the data measured or the information of signal.
According to the identifier's of the present invention identity or the method for mandate, have following steps:
A) install secret data of input by this people to a kind of, or measure this people's individual characteristic feature, especially biological characteristic by described device by sensing equipment;
B) data of the described input of check or the sensing data of described mensuration in described device;
C) if this assay for certainly, is then carried out scrambled to the input data in described device;
D) be to realize to the check of the sensing data of the data of described input or mensuration by comparing with the reference data in the memory device that is stored in described device with these data or by the characteristic of its derivation;
E) come described input data are carried out scrambled by the key within the storer that is stored in described device, and the input data crossed of described scrambled do not contain about by the data of user's input or about the information of the sensing data measured.
Therefore; idea behind the present invention is; people's characteristic is not sent to external system; but measure these data or signal by the device that the donor had; by described device this device is carried out scrambled from the input data that external system obtains then; like this, described external system is not to discern his mandate from the donor's of need protection feature, but discerns from the correct scrambled of described input data.At this, the scrambled of Feature Recognition and input data is preferably to carry out in preventing device unauthorized access, as safe as a house.The characteristic that can prevent a people is effectively abused thus.
Description of drawings
Also tell about the present invention with reference to the accompanying drawings by preferred embodiment below.
Fig. 1 shows the structure of the preferred embodiment of the invention briefly, and has illustrated the flow process of the inventive method simultaneously.
Embodiment
The present invention is used to measure and analyze data or signal, includes in particular for the device of identifier's identity or mandate etc.: the equipment (DE) that is used for determination data (D) or signal (S); Be used to check the data in described device, measured or the equipment (DV) of signal; And the equipment (KE) that is used for the input data (ED) in the described device are carried out scrambled.
The equipment of described determination data or signal can be the simple keyboard of computing machine or communication terminal or other mini-plant.Certainly,, also can adopt a kind of image input media, for example can have the pressure sensing input face of underlying display etc. for replacing this keyboard.This input equipment is particularly suitable for measuring key word or signature.
But the equipment that is used for determination data or signal also can be microphone, or video camera or fingerprint sensor.Especially the miscellaneous equipment that is used for measuring people's biological characteristic also can be infered.Data of being measured or signal can comprise literal, numeral, person's handwriting, relevant sound sample, voice word or sentence or the like, and they are suitable for differentiating or identifier's mandate.Can directly or in extraction characteristic (MD) check these data or signal by inspection machine (DV) afterwards.According to the present invention, this inspection machine is positioned within the described device.Therefore, described data that need check or signal or the characteristic extracted from their can not be left described device when check.
For this reason, if the user occupies the infringement that this device also can be got rid of illegal person separately at least, then he just can guarantee that its data are not abused.If check is carried out successfully (affirming), the data and the signal that is to say described mensuration indicate input by the authorized user execution from the meaning of checking, and then import the input data (ED) of described device from the outside and just carry out scrambled by scrambled equipment (KE) in this device.
At this moment, external system just can be tested to this correct scrambled of importing data, identifier's identity or its mandate thus.To this, only need read the input data that described encrypted coding crosses and test.This people's characteristic is positioned within the described device, has therefore prevented to be abused.
Identifier's data can utilize various method to realize in described device.On the one hand, directly from the data or signal measured, or when from the characteristic of its extraction, calculating needed key to input data encryption coding.Another kind of possibility is, described characteristic is input in a kind of discrimination function, directly draws assay by this disconnected other function with the form that is/denys judgement.On the contrary, the simplest is that the reference data (RD) of will be stored in described data, signal or the characteristic storer (SE1) with described device compares.But two kinds of methods that the front is told about have individual advantage, and the data that need protect itself are not stored in the described device exactly, have therefore prevented abuse better.
If directly do not calculate described key (K) in described device, it is more favourable so it being stored in the storer (SE2) of this device.Another kind of possibility is that adopt the algorithm of a kind of " fixedly connected " to carry out scrambled, wherein said key implicitly is hidden among the structure of circuit.But it is higher that the shortcoming of this method is a manufacturing expense.This key of clearly storing is positioned at and is stored in case of necessity near the reference data within the described device, individual special parameters, otherwise this device is general device.
Yet, except being applicable to symmetric key of the present invention in principle, can also adopt asymmetric key right especially.In this case, described key (K) be donor individual, the also promptly secret key that keeps.On the contrary, the input data that adopt disclosed key in the external information system of identifier's identity or mandate scrambled to be crossed are decrypted.
Especially, at random or pseudorandom character string, Serial No. or symbol sebolic addressing be fit to be used as the input data (ED), the correct scrambled of these sequences can be tested easily by the checking system of outside, and in fact they can not be by invador's prophesy or conjecture.And the recovery time of this symbol sebolic addressing can be sufficiently long, also promptly is actually endless.
