Abstract

A method for preventing hijacker from using cipher to withdraw money includes setting a cipher keyboard of payment collection tool with a joint for preventing hijacking, inputting an easily remembered added number lower than cipher number into added value setting memory by depositor, obtaining an alarm cipher added by added number and cipher number by added value calculator, giving the alarm cipher to hijacker or using it to alarm when depositor is forced by gangster; although the alarm function can be selected by the depositor, the bank payment and collection tool only has the function, even if only a few depositors select the alarm function, the alarm tool also shakes criminals, and robbers are afraid of withdrawing money from banks even if asking for passwords from the depositors, so the method can reduce the occurrence of illegally obtaining password cases.

Description

Method for preventing hijacker from darting to draw money by using password

Technical Field

The invention belongs to the field of financial theft prevention, and particularly relates to a method for preventing a hijack person from darting to draw money by using a password.

Background

It is known that current bank payment collection instruments (including bank cards, passbooks, deposit slips, etc. held by depositors, and third party payment instruments POS) use passwords for their operation. Robbers often cause various injuries to depositors in order to obtain passwords, cases for killing depositors also occur in places such as the Guantown of the Mongolia, the mountain, and the like; the xi' an railway station also has a case that a victim is cheated to drink a soul medicine and speak a password; the baby chicken has a case that the baby chicken takes the password swiftly by taking the tax with the car to be returned, so that a plurality of depositors suffer economic loss; and after robbers and bank cards are robbed in the residential and Maran store, the password is verified by a POS machine on the spot, and then the bank is taken out, otherwise, the depositors and other major cases are killed. Although the password of the dynamic password card is dynamic, criminals such as robbers can also make a case, so even if various advanced verification methods are provided, the password still needs to be used. If a method is provided, the criminal can be warned in time without being detected by criminals when the case happens, so that the public security personnel can timely stop the crime and save the hostage, and the method can not only prevent the criminal from being surprised, but also ensure the hostage safety to the maximum extent and prevent the crime.

Disclosure of Invention

The purpose of the invention is: a method for informing the password to the robber when the depositor is hijacked by the ruffian and forced to say the password, and the robber can be immediately detected by the public security department when using the password is provided to reduce the forcing and damage.

The purpose of the invention is realized as follows: the electronic change-over switch is led out from a password keyboard of the payment collection tool, and the password keyboard is respectively connected to A, B, C contact points of the payment collection tool; when depositor deposits money, the password hit out on the password keyboard is input into the 'bank account password authentication system' from one line of the A contact, and the other line of the A contact is connected with the input end of the 'password memory'; the B contact is an anti-hijack contact, a depositor can input ' added value ' into a ' added value setting memory by using the B contact, the output end of the ' added value setting memory ' and one output end of the ' cipher memory ' respectively input the added value and the cipher number into a ' added value calculator ' for addition calculation, and store the calculation result into an ' alarm cipher memory ', and the output line of the ' alarm cipher memory ' transmits the alarm cipher into one input end of each double AND gate in the ' alarm cipher and gate array circuit '; the other output end of the password memory is connected with one input end of each double AND gate in the password and gate array circuit; the password input switch circuit is connected with the trigger end of the password input switch circuit to drive the password output switch circuit to be switched on, so that the password number in the password storage is input into the bank account password authentication system to be authenticated; the output end of the alarm password and gate array circuit is also connected with an alarm circuit; the method is characterized in that: the value-added number in the value-added setting memory is a number which is input by the user using the password keyboard and has a smaller number of digits than the password.

Thus, when the depositor deposits money, in order to prevent the depositor from having to speak out the password when encountering the brigade's will, besides setting up the password as usual, the depositor can also input the password number, such as six-digit password number 976543, to the ' bank account password authentication circuit ' for authentication according to the bank rules, according to the prompt of computer screen or bank staff, voluntarily connect the point B through the password keyboard, and input a password ' added value ' by keyboard, the added value should not exceed three-digit number, generally take two-digit number without zero, because two-digit number without zero, such as one hundred, including negative number, so the brigade is afraid of ' card eating ' or delayed withdrawal, and difficult to deduce the password set up by the depositor in short time, so only believe the depositor or give up. The depositor can add the most easily remembered and added value number, such as: 11. 12, 13, 14, 22 … …, etc., when one group of numbers is knocked out by the keyboard, if "11", then "11" is stored in the value-added setting memory, and the value-added calculator adds "11" and the set password number 976543 to obtain a 976554 alarm password which is stored in the alarm password memory. When the depositor needs to withdraw money, according to the prompt of a computer screen or the prompt of bank staff, a password keyboard is connected with a point C, six-bit password numbers are input, if the six-bit password numbers correspond to the six-bit password numbers preset in a password storage one by one, two input ends of each double AND gate in a password and gate array circuit are in positive pressure, signal current is output when the output end of the six AND gate connected with the double AND gates outputs, and the current triggers a password output switch circuit to be opened, so that password digital signals in the password storage enter a bank account password authentication system, and the withdrawal is successful after authentication. When the depositor is hijacked, because the depositor sets the password earlier, the added value is a simple two-digit number of 11, so that the depositor can tell the robber the alarm password 976554 only by slightly calculating after remembering the added value of 11 while delaying the time, and although the number cannot make the password and the gate array circuit output, the alarm password number 976554 can make the alarm code and the gate array circuit open and output an electric signal just like the same principle of the password output switch circuit, and the output current can also trigger the password output switch to open, so that the password number can enter the bank authentication system and the screen can display that the password number passes the authentication. So that the robber can believe that the depositor does not cheat him, and therefore does not discuss the password or report back. However, when the alarm code and the gate array circuit output signal current, the output circuit has a branch circuit to trigger the alarm system of the bank, and the alarm system takes anti-robbing measures immediately. In order to prevent robbers from finding that the alarm password is obtained and damaging depositors, banks can first pass through a display screen or spoken language, so that general faults of computers, such as 'card eating' and 'delayed input again' are avoided and a period of withdrawal is delayed. The alarm is timely, so that the kidnapping case can be speeded up in the detection speed, and the injury of robbers to depositors can be effectively prevented. Because the password 976543 and the added value 11 have different digits, the depositor cannot remember the two by mistake, if the two digits are not remembered by mistake, the two digits cannot be used as the password in the bank, and therefore, the occurrence of false alarm situation can be completely avoided. The method can be voluntary, so that some people may be troubled and do not intend to put the keyboard on the point B and input the added number, but as long as a few people carry out the method, the robber feels shocked, even if the depositor gives the password to the robber in the future, the robber is afraid of inputting the password provided by the victim to withdraw money from a bank due to the feelings of the robber, and the anti-theft password can also enable the depositor to give an alarm in secret when being subjected to the vigilance. These uses of the anti-theft password will reduce the probability of criminals to succeed in the crime, thereby reducing the occurrence of crime.

Detailed Description

Fig. 1 is a schematic diagram of the operation of the present invention. In fig. 1, 1 is an alarm password memory, 2 is an added value calculator, 3 is a keyboard key-out memory, and 4 is a password keyboard (abbreviated as "keyboard"). The device comprises a value-added setting memory 5, a password output switch circuit 6, a password memory 7, an alarm password AND gate circuit 8, a password AND gate array circuit 9, a bank account password authentication system 10, an electronic transfer switch K, an alarm circuit contact H and an isolation diode D. Through the A contact, the depositor can input the password into the 'bank account password authentication system' as usual, all passwords are stored by the cryptograph in the system, and the other line is connected with the input end of the 'password memory'; the B contact inputs the added value number into an added value setting memory, the added value setting memory and the password number are respectively input into an added value calculator to be calculated by the output end of the added value setting memory and one output end of the password memory, the calculation result is stored into an alarm password memory, and an output line of the alarm password memory sends the alarm password into an alarm password and gate array circuit (see figure 2 with internal components of a gate array); the other output end of the 'cipher memory' is connected with the input end of the 'cipher AND gate array circuit'; c is a contact point used when the depositor withdraws money, the verification password output by the depositor on the password keyboard is input to the other input end of the alarm password and gate array circuit and the other input end of the password and gate array circuit through the circuit of the 'keyboard key-out memory', the output ends of the password and gate array circuit and the 'alarm password and gate array circuit' are both connected with the trigger end of the 'password input switch circuit' to trigger the 'password output switch circuit' to be opened, the circuit simulates that the password number is input to the 'bank account password authentication system' for authentication when withdrawing money at ordinary times, the numbers in the 'alarm password memory' and the 'password memory' are stored as the account number of each depositor, and other memories automatically set to zero after the user finishes the operation), the output end of the 'alarm password and gate array circuit' also has an alarm circuit contact point H, the alarm signal of the alarm circuit is only used for the bank staff to know and observe and give an alarm to the public security department.

Fig. 2 is a schematic diagram of the internal structures of the alarm password and gate circuit and the password and gate circuit in fig. 1. In the figure, 1 is an alarm password memory, 3 is a keyboard key-out memory, 6 is a password output switch circuit, 7 is a password memory, a dotted line frame 8 in the figure represents an alarm password and gate array circuit, the circuit comprises six and gate groups of one, ten, one hundred, one thousand, ten thousand and one hundred thousand, each group comprises 1-10 numbers, y9, y7, y6, y5, y5 and y4 in different digits represent one of 10 double and gates in different digits. y9 represents the AND gate representing "9 ten thousand" in the hundred thousand digits, y7 represents the AND gate representing "7 ten thousand" in the ten thousand digits, and so on. In the figure 11, 6 AND gates are arranged in an alarm password and gate array circuit, and 10 double AND gates on each digit are connected with one input end of the 6 AND gates. In the figure, a broken line frame 9 represents a password and gate array circuit, the circuit comprises six and gate groups including one, ten, one hundred, one thousand, ten thousand and one hundred thousand, each group comprises 1-10 numbers, Y9, Y7, Y6, Y5, Y4 and Y3 on different digits, and one of 10 double AND gates on different digits is represented. Y9 represents the AND gate representing 9 ten thousand in the hundred thousand digits, Y7 represents the AND gate representing 7 ten thousand in the ten thousand digits, and so on. And 12 is a 6 AND gate circuit in a cipher AND gate array circuit, and 10 double AND gates on each digit are connected with one input end of the 6 AND gate. 10 is the bank account number password authentication system, H in the figure is the contact of the alarm circuit, D is the isolation diode. Each output pin of the "cipher memory" 7 in fig. 2 represents an output number of 1-10 of one digit, and similarly each output pin of the "alarm cipher memory" and the "keyboard key-out memory" represents an output number of 1-10 of one digit (the first digit on the right is one digit, and the digit is raised to the left). Therefore, if the password number of the password memory is 976543, only when the depositor clicks 976543 on the keyboard (i.e. when the six-bit output end of the keyboard key-out memory is also 976543), all the 6 double and gates listed in the dashed line box password and gate array circuit 9 are turned on, and the 6 and gates indicated by 12 are also turned on, so that the password output switch circuit is triggered, as shown in fig. 1, the password in the password memory is input into the bank account password authentication system through the password output switch circuit as the depositor withdraws money, and authentication is passed. When the robber outputs the alarm password 976554 from the 'keyboard key-out memory' according to the depositor, the ones and 10 digits can not make the ones and tens of the 'password and gate array circuit' conducted, the 6 and gate represented by 12 can not be conducted, and the number 976554 of the alarm password can match with the number of the double and gate of the 'alarm password and gate array circuit', so the 6 and gate represented by 8 is conducted, the same output current triggers the 'password output switch circuit' through the isolating diode, the password in the 'password memory' is also input into the 'bank account password authentication system' through the 'password output switch circuit', and the robber can not know that the password is changed through authentication. At this time, the other path of the output of the 6 AND gate, which is shown by 11, is connected with an alarm contact H, so that the bank and the public security department receive the alarm, thereby taking measures in time, preventing crimes and saving the quality of people.
