All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In consideration of the problems that the existing security detection mode of the financial payment terminal is poor in detection integrity and time-consuming and labor-consuming, the embodiment of the invention provides a payment terminal detection device, a system and a method, the technology can be applied to security authentication or detection of the financial payment terminal by an authentication mechanism, a supervision mechanism or a detection mechanism of the financial payment terminal, and can also be applied to spot check and security control of mass-produced products of the payment terminal by a detection mechanism, a payment terminal manufacturer or law enforcement personnel, and the technology can be realized by adopting related software and hardware and is described below through embodiments.
Embodiment one:
referring to fig. 1, a schematic structural diagram of a payment terminal detection device includes the following acquisition module 10: an image collector 101, a sound collection module 102, a power consumption collection module 103, a field intensity collection module 104, a transaction time collection module 105 and a firmware collection module 106;
the image collector 101 is used for collecting external characteristics of the payment terminal; wherein the external characteristics include one or more of a size of the payment terminal circuit board, a trace, a component mounting location, and a component model; the image collector includes a CMOS (Complementary Metal Oxide Semiconductor ) camera, or a CCD (Charge-coupled Device) camera.
In the detection project of various characteristics of the payment terminal, consistency of external characteristics of the circuit board is an important characteristic; specifically, the circuit board external characteristics include: the physical size of the circuit board, the layout and trend of the circuit on the circuit board, the installation position of the circuit board components, the selection of the circuit board components and the like; the image information of the financial payment terminal is acquired in a computer vision mode, and whether the external characteristics of the payment terminal circuit board are consistent with the external characteristics of the payment terminal for inspection can be detected by utilizing image processing software or an image processing algorithm.
The sound collection module 102 is configured to collect key feedback sound of the payment terminal; in order to improve the interaction experience between the payment terminal and the user, after the user presses a key on the terminal, the terminal prompts the user to actually press the key in a short-time voice manner. The payment terminal attack method is generated by comparing and analyzing the sound when the user presses the key to obtain the sensitive information such as the account password of the user; each key of the payment terminal has specific sound feedback, and although the subtle gap cannot be distinguished by the human ear, lawbreakers can detect which specific key is pressed through related equipment; in addition, because the differences of the manufacturing process of the payment terminal or unreasonable terminal structural design and the like can possibly cause inconsistent key feedback, sensitive information can be exposed when a transaction user uses the payment terminal with problems to conduct transaction; therefore, the sound collection module collects each key feedback sound of the terminal to be detected, and the consistency of the key feedback sounds is judged by utilizing the audio processing circuit and the computer audio processing algorithm.
The power consumption collection module 103 is used for collecting static power consumption and dynamic power consumption of the payment terminal; the static power consumption is the power consumption when the payment terminal is started but the instruction is not executed; the dynamic power consumption is the power consumption when the payment terminal executes the instruction;
specifically, certain electric quantity is consumed in the running process of the financial payment, and the power consumption at the moment that the payment terminal is started up but does not perform any operation is defined as static power consumption; the power consumption at which a certain action or a certain transaction process is performed at the terminal is defined as dynamic power consumption. It should be noted that the static power consumption of each financial payment terminal has only one data, while the dynamic power consumption can change according to different instructions or transaction types; in practical application, static power consumption of the payment terminal and dynamic power consumption of the payment terminal when common instructions or actions occur can be used as detection standards of consistency of the financial payment terminal.
The field intensity acquisition module 104 is used for acquiring the radio frequency field intensity emitted by the payment terminal; in actual implementation, the field intensity acquisition module 104 is further configured to acquire a radio frequency field intensity emitted by a contactless reader disposed in the contactless payment terminal. In the process of contactless IC card transaction, the radio frequency power emitted by the contactless terminal is an important measurement parameter. In the related specifications, parameters of the emitted radio frequency field of the non-contact card reader are also specified; the field intensity acquisition module is used for detecting that the radio frequency field energy emitted by the non-contact card reader can not meet the standard requirement and simultaneously carrying out consistency comparison with the standard payment terminal.
The transaction time acquisition module 105 is configured to acquire transaction time of the payment terminal; in the relevant specifications of the payment terminal, a transaction time is specified for each type of transaction, within which specified transaction or action should be completed. The transaction time acquisition module can acquire the transaction time of financial payment, and further judge whether the transaction time of a certain transaction meets the requirements of specification and consistency.
The firmware collection module 106 is configured to collect firmware programs of the payment terminal; the firmware acquisition module extracts a hash value (also called a hash value) of a firmware program code in the financial payment terminal and uploads the hash value to the cloud server; simulating transaction is carried out on the cloud platform through a cloud desktop, and a transaction result is uploaded to a cloud server; meanwhile, in order to prevent the hash value of the payment terminal from being tampered, the firmware acquisition module can download the random number to generate the hash value and upload the hash value to the cloud server.
The acquisition module 10 receives an acquisition instruction according to a man-machine interaction interface of the peripheral, starts a corresponding acquisition module according to the acquisition instruction to acquire data, and sends the acquired data to a server of the peripheral through the man-machine interaction interface so that the server analyzes and processes the data to generate a security detection report of the payment terminal.
According to the payment terminal detection device provided by the embodiment of the invention, according to the acquisition instruction of a user, the acquisition modules such as the image acquisition device, the sound acquisition module, the power consumption acquisition module, the field intensity acquisition module, the transaction time acquisition module, the firmware acquisition module and the like are used for acquiring the data such as the external characteristics, the key feedback sound, the static power consumption, the dynamic power consumption, the radio frequency field intensity, the transaction time, the firmware program and the like of the payment terminal, and analyzing and processing the acquired data through the server, so that a security detection report of the payment terminal is generated; the method can completely detect the performances of the payment terminal in all aspects, and has the advantages of short detection time, low cost and high accuracy of detection results.
Referring to a specific structural schematic diagram of a payment terminal detection device shown in fig. 2, on the basis of the device shown in fig. 1, the acquisition module 10 further includes a size acquisition module 201 and a weight acquisition module 202;
the size acquisition module 201 is configured to acquire a size of the payment terminal; the size acquisition module is realized by a ranging module, and the ranging module can adopt a laser ranging mode; the principle of the method is that a laser transmitting part of the laser ranging module transmits a beam of laser, the laser is reflected when the laser irradiates an object to be detected, a laser receiving part of the laser ranging module receives the reflected laser and then transmits a notification to a controller of the laser ranging module, and the controller can calculate the distance between the object to be detected and the laser probe by calculating the time difference between laser emission and laser receiving. The size acquisition module can detect the thickness of financial payment through the laser ranging module.
Further, the size acquisition module can be realized in various modes such as a laser ranging unit, an ultrasonic ranging unit, an infrared ranging unit, a radar ranging unit and the like; in actual implementation, the device may be provided with a laser ranging unit, an ultrasonic ranging unit, an infrared ranging unit, and a radar ranging unit, or alternatively or partially provided with the above units.
Specifically, when the size acquisition module is implemented by a laser ranging unit, the size acquisition module comprises a laser transmitter, a laser receiver and a controller; the laser transmitter is used for transmitting laser beams; the laser receiver is used for receiving the laser beam reflected by the payment terminal; the controller is used for recording a first moment when the laser transmitter emits the laser beam and a second moment when the laser receiver receives the laser beam reflected by the payment terminal, determining the distance between the payment terminal and the laser transmitter according to the time difference between the first moment and the second moment, and obtaining the size of the payment terminal according to the distance.
The weight acquisition module 202 is used for acquiring the weight of the payment terminal; in actual implementation, the weight acquisition module is a high-precision weighing module; in the mass production process of the payment terminal, manufacturers may replace the component types, the housing materials, etc. of the payment terminal in consideration of benefits; typically, the same components, which are made of different materials, will have some variation in weight; therefore, the weight of the financial payment terminal can be used as an important index for security consistency detection.
For positioning and moving the plurality of acquisition modules, the apparatus further comprises a mobile station 203; the acquisition module is disposed on a mobile station 203, which is used to adjust the position of the acquisition module. In detecting relevant parameters for financial payments, the location of the relevant detection sensor may need to be dynamically adjusted according to the specific financial payment due to the variability between financial payments, which may be accomplished by the mobile station. In actual implementation, the moving stage may be an XYZ-axis electric moving stage of a ball screw type or an XYZ-axis electric moving stage of a synchronous belt type. The position of the acquisition module can be adjusted according to the characteristics of different types of payment terminals, so that the payment terminals can be detected more quickly and accurately.
Considering that the data amount of the sound signal collected by the sound collection module is large and the analyzability is poor, the sound collection module comprises a sound sensor and a sound processing circuit; the sound sensor is used for collecting sound signals fed back by keys of the payment terminal; the sound processing circuit is used for converting the sound signal into an electric signal and sending the electric signal to the server so that the server can conduct feature extraction on the electric signal to generate key sound feature data of the payment terminal. The method can acquire the characteristic data of the sound signals generated by the payment terminal, and further detect and analyze the payment terminal through the characteristic data.

The specific setting position of the server 302 is not particularly limited in fig. 3.
The server 302 compares the received data with the pre-stored sample data of the payment terminal, and generates a security detection report of the payment terminal according to the comparison result; the sample data of the payment terminal stored in advance is provided by the payment terminal in a sending stage and can be stored in a sample reservation library of the server.
