CN101739121A - Peer and intercept preventing password input device without any display parts - Google Patents

Abstract

The invention relates to a password preventing input device without any password display parts which is arranged on a panel and can realize input only by sound guiding. By utilizing random principle, all the operation stands for indefinite contents which can not be copied, and the recording and analysis of all video equipment are prevented. Just five keys are repeatedly pressed during the whole process, and confidence can not be divulged through sound. The device can prevent the password from being analyzed by all video and audio means. The structure is very simple and the confidentiality is high. The device can be applied to high security fields, such as military field, scientific research institutions, banks, finance and the like.

Description

Do not need the peep-proof anti-eavesdrop PIN PAD of any demonstration

Affiliated technical field

The present invention relates to a kind of cipher input, its special character is no any password display part on the panel, has only shift key and enter key, tells the end user with earphone with encrypted message, makes other people have no way of peeping.Can prevent that input process from peeping or carrying out the password that video record, audio analysis cause and leaking because of other people, have highly confidential characteristic.

Background technology

The existing password input media is divided into rotary-type two kinds of keyboard-type and numeral substantially, and its common feature is that all demonstrations, Warning Mark all are placed on the outside.Be security code safety, the user need make in use and significantly hide or block action, or guarantees that it can not have people or watch-dog to exist in certain limit on every side.Otherwise, other personnel also can observe directly from the side or observe, write down, analyze by telescope, video camera etc., button sound when individual device can be recorded down input is analyzed the button of being pressed, thereby infers and the password of inputing, and the security of password has been caused very big hidden danger.

Summary of the invention

Technical matters: the drawback that the password that brings for the demonstration indicating device that overcomes the ordinary password input media exposes, makes the person of peeping to can be observed input action leaks, accomplish not influence the user and normally input password, but make in addition anyone all can not observe or infer and the password of being inputed.

The technical solution adopted for the present invention to solve the technical problems is: do not establish any password on the panel and show, observe part, only finish input process by the sound guidance user, make anyone have no way of peeping, and used stochastic technique, make all inputs uncertain, not unique, do not represent concrete password, make other people have no way of deciphering at all by duplicating input process.

By being set at random, the password start bit guarantees that operating process can not be replicated.This device be by any random digit of one from 0 to 9 of producing by Computing as the password start bit, this numeral is produced by random function, without any rule, imports pilot signal by pronunciation device as password.

In case institute's installed device need be inputed password, system power-up, earphone on the system prompt band, computing machine produce a random digit as start bit, in earphone, quote with female voice, by the displacement key, in the earphone together with the time quote corresponding numeral.If this numeral is a needed number just, can realize selected by " input " key.Reselect by ascending order and descending if not then press 4 displacement keys, in earphone, hear needed number, press " input " key.Select next bit again with quadrat method, until all being totally lost.Inform against somebody sign indicating number in the earphone and join end to end ring shift for the 0-9 numeral.

The invention has the beneficial effects as follows, no any password display device on the panel, have only simple displacement key and enter key, because the password start bit is unfixing, make each key not represent concrete meaning, other people have no way of at all inferring that institute inputs password, and are not afraid of and spy on and imitate, make the password input process very safe, have highly confidential property.And it is simple in structure, simple to operate.

Embodiment

Fig. 1 is the outward appearance of PIN PAD, and five buttons of panel central authorities are enter key and left and right sides options button, and the next door is " input " key.Panel construction is extremely simple.

In Fig. 2, "+" represents ascending order ,+1 ,+2 respectively password figures increase by 1 and 2, "-" represent descending ,-1 ,-2 respectively password figure reduce 1 and 2, in case the required password figure of appearance then press " input " key in the earphone.

Institute's erecting equipment is an ATM in Fig. 3, and (5) are coin discharge, and (3) are monomer full-enclosed earphone, must take off and is with from suspension member during use, and (4) are the earphone lead of band coat of metal.Left hand is held earphone and is close to left ear during use, right-hand operated input password.

Work schedule:

PIN PAD is received the host computer ready signal, processor produces the random digit between the 0-9 to energising preliminary work---system alert is taken earphone and is with---, exist in the register, if and in earphone, quote---needed number, press " input " key, with information input processor in the register---if not, ("-" "+" represents descending respectively then to press the selection of displacement key, ascending order), earphone is quoted the representative numeral at once, revise register information simultaneously---listen the earphone prompting, occur up to needed number---press " input " key, the machine recognition register information, by " determining " bond bundle input process, the register zero clearing---processor is passed to host computer with input results to the numeral chosen of input---with quadrat method whole passwords of being totally lost---

Claims (4)

1. a PIN PAD can realize the input of various digital passwords, it is characterized in that: no any password display device on the panel, realized that by earphone the guiding input process height of encrypted message prevents that other people from observing, peeping.Used stochastic technique, made other people have no way of deciphering at all by duplicating input process.Have only a button, prevent to analyze password by recording.

2. PIN PAD according to claim 1 is characterized in that: do not establish any password and show and establish device, only the guiding input process by institute's subsidiary earphone sounding realization encrypted message, only cooperate with options button, do not reveal the input content, prevent to peep, realize maintaining secrecy.

3. PIN PAD according to claim 1, it is characterized in that: the different random number that at every turn provides between the 0-9 by computing machine comes as the password start bit, the order of operation of simple record user on panel become not to be had in all senses, do not reveal the input content, prevent to observe and peep, stopped the possibility that the stranger deciphers owing to the imitation input process.

4. PIN PAD according to claim 1 is characterized in that: only be provided with 4 displacement options buttons that use repeatedly, press at every turn and all represent uncertain content, can prevent to break a code by high-resolution recording means analysis.
