Description

Lie person response information acquisition method, device and system and storage medium

Technical Field

The embodiment of the invention relates to the technical field of computers, in particular to a method, a device, a system and a storage medium for acquiring response information of a lie detector.

Background

The test process of the existing lie detector response information acquisition system mainly comprises the steps that professional lie detectors sequentially inquire and record response information of the detected persons according to a fixed question sequence (the response information acquisition system of the detected persons is operated by the testers to record). Lie detectors need to be focused on the state and actions of the person under test at all times. If the body of the person to be tested has movements, it is necessary to remind him to remain stationary, since the movements of the body (such as small amplitude bends of the fingers) can affect the physiological signal, interfering with the lie detection process. After the questions of the lie detector are answered, it is necessary to observe whether the physiological signals of the detected person return to the baseline level, so as to prevent the physiological signals of different questions from interfering with each other. Therefore, lie detectors need to be fully attentive to operate, observe and evaluate during lie detection.

However, currently, the number of lie detectors nationally is very small, and only tens of people are professional. If this lengthy and tedious task is made affinity by these people, lie detection tools have very limited application in reality. Moreover, it is too heavy and inefficient for lie detectors. This limitation also severely affects the use and popularization of lie detection techniques.

Therefore, how to pull out lie-detecting personnel in the complicated and complicated process of collecting lie-detecting parameters greatly reduces the effort input of the lie-detecting personnel in the lie-detecting process, reduces the work load of the lie-detecting personnel, improves the work efficiency, and realizes the wide popularization of the lie-detecting technology to be the technical problem to be solved urgently.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. 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.

For the purpose of facilitating an understanding of the embodiments of the present invention, reference will now be made to the following description of specific embodiments, taken in conjunction with the accompanying drawings, which are not intended to limit the embodiments of the invention.

Fig. 1 is a schematic flow chart of a method for acquiring response information of a person to be detected according to an embodiment of the present invention, where the method is executed by a system for acquiring response information of a person to be detected, for example, a lie detector or other systems capable of acquiring response information. In this embodiment, a lie detector is taken as an example. As shown in fig. 1, the method includes:

Step 110, playing the pre-configured voice file of lie detection problem according to the preset sequence.

Specifically, the lie detection problem is a preset problem, and is then input into the lie detector in text form. Then, the lie detection problem in the text form is converted into a voice file by a text-to-voice conversion system in the lie detector. Alternatively, the lie detection problem is directly input into the lie detector in the form of a voice file. In a specific example, a voice file for lie detection problems may be automatically generated by voice synthesis software like text to speech (TTS for short).

And, when the operator controls the lie detector to operate, the lie detector plays the voice files of the lie detection problem which are already configured according to the preset sequence.

Optionally, in order to ensure that the tested person can timely learn about lie detection problems. The method may further comprise:

when playing the lie detection problem, the text content of the lie detection problem is displayed on the display screen of the lie detector for reference by the person to be detected.

Step 120, collecting response information of the lie detector in the process of processing the current lie detection problem.

Specifically, the response information made by the lie detector includes preset item information. Optionally, the preset item information may include: the content of the answers made by the lie detector to the current lie detection question and the second body action information in the process of answering the current lie detection question.

And 130, storing the reaction information when the preset item information in the reaction information is determined to meet the corresponding preset standard.

Specifically, as introduced in step 120, the preset item information may include answer contents made by the person to be detected for the current lie detection question and second body motion information in the process of answering the current lie detection question. Then, only when the answer content and the second body action information of the current lie detection question respectively meet the preset criteria corresponding thereto, the reaction information can be stored.

In a specific example, determining whether the answer content of the current lie detection question meets the preset standard corresponding to the answer content, specifically includes:

when the answer content is determined not to be the preset content, the answer content is determined to accord with the preset standard corresponding to the answer content.

Optionally, the preset content is used for indicating that the detected lie person does not hear the current lie detection problem clearly. For example, the preset content may include, but is not limited to, the following: what is? "not hearing clearly", "hearing too clearly", "will be understood? "o? "and the like.

If the content answered by the lie detector is not similar to the content, then the answer content is determined to meet the preset standard corresponding to the answer content. Here, the preset criterion corresponding to the answer content is to determine that the respondent gives a positive answer to the lie detection question. Whether the positive answer is positive or negative is temporarily taken here. Further explanation will be made later on for this problem.

Optionally, if the answer content is determined to be the preset content, after collecting the response information of the lie detector in the process of processing the current lie detection question, the method further includes:

and when the second physiological information and the third body action information respectively accord with the preset standards corresponding to the second physiological information and the third body action information, replaying the current lie detection problem so as to acquire the response information of the person to be detected in the process of processing the current lie detection problem later.

Specifically, after the person to be detected does not hear the previously asked lie-detection question, in order to ensure that the state of the person to be detected is in a state suitable for the question, it is also necessary to collect the second physiological information and the third physical action information of the person to be detected.

And if the second physiological information and the third body action information respectively accord with the preset standards corresponding to the second physiological information and the third body action information, replaying the current lie detection problem. If either does not, a determination is made as to why it does not. For example, if the person to be detected is shaking or if there is a certain fluctuation in the physiological information, it is necessary to stop for a certain period of time, let it rest for about 15 seconds, and re-detect. If the body movement is excessive, the staff informs the lie detector of reducing the movement and keeping the movement stable. The system acquires the second physiological information and the third body motion information again, and judges whether the second physiological information and the third body motion information respectively accord with preset standards corresponding to the second physiological information and the third body motion information. Until it is determined that the second physiological information and the third physical action information respectively meet the preset standards corresponding to the second physiological information and the third physical action information. In practice, the system continuously collects the second physiological information and the third physical action information, and then makes a judgment. If the judgment is unqualified, the system can give a prompt in a voice form, so that the lie detector keeps calm, and the actions are not excessive and remain motionless as much as possible.

How to determine whether the second physiological information, the second physical movement information, and the third physical movement information respectively meet the preset criteria corresponding to the second physiological information, the second physical movement information, and the third physical movement information will be described below.

Specifically, determining whether the second body motion information meets the preset standard corresponding to the second body motion information specifically includes:

according to the second body motion information, determining a body motion change intensity value within each first preset unit time in the process of answering the current lie detection problem;

when it is determined that the intensity values of body motion changes in all first preset unit time in the process of answering the current lie detection question meet the first preset conditions, it is determined that the second body motion information meets the preset standard corresponding to the second body motion information.

In particular implementations, the body motion information may be acquired in the form of image acquisition. For example, body motion images of a person to be detected are acquired by a camera and transmitted to a lie detector. Lie detectors can use frame difference to quantify body motion pictures.

For example, the following method may be employed: the webcam is invoked by OpenCV, and then two frames are acquired using read () to generate frame1 and frame2, and the absolute difference between the frames, framediff, is calculated continuously using absdiff (frame 1, frame 2). And then summing the returned difference values to obtain the body motion change intensity value between the two frames of images, wherein the body motion change intensity value is used as an intensity index of picture movement. This approach is used for the overall change of the picture and not just for the face or body movements. This calculation is more suitable for this scenario, since any change in the environment may cause a change in mental state.

In particular implementations, in general, a lie detector can record question asking start times, question ending times, lie detector start answering questions times, and lie detector answer ending times.

Empirically, the calculation starts at the moment after the end of the lie detector question, and ten or more seconds later, the next question is ready to be asked, but it is considered that the lie detector may not be completely calm or have a certain interference factor, so that the lie detector may have a certain physical action. Thus, the lie detector may extract frame images within a preset period of time from the end of the current lie detection question query, for example, from the corresponding image after the 10 th second until all images that the lie detector answers the question. And comparing all the body motion change intensity values in the first preset unit time. For example, a body motion change intensity value is acquired every two seconds of an image. In a specific example, the extracted image is, for example, an 11 th second image, a 12 second image, a 13 second image, or a 14 second image … …. Taking 2 seconds as the first preset unit time, it is then necessary to determine the body motion change intensity value between the 11 second image and the 12 second image. The body motion change intensity value between the 13 th second image and the 14 th second image is then calculated. Alternatively, the comparison is repeated, that is, the body motion change intensity value between the lower 11 second image and the 12 th second image, the body motion change intensity value between the 12 th second image and the 13 th second image, and the like are compared. And when all the body motion change intensity values in the first preset unit time meet the first preset conditions, determining that the second body motion information meets the corresponding preset standard. The first preset condition is that the intensity values of the body motion changes in all first preset unit time are smaller than a preset threshold value (specifically, the first preset condition is set according to statistics of experimental data, and the first preset condition comprises that the intensity of illumination, the temperature or the humidity and the like all influence the preset threshold value under different environments).

The above-mentioned explanation is that the body motion change intensity value in the first preset unit section actually has a plurality of frames of images in each second. Then, in order to reduce the amount of calculation, a few frame images per 1 second may be selected to perform the above operation. For example, only two frames of images are selected per second.

When determining whether the third body movement information meets the preset standard corresponding to the third body movement information, the principle is similar to that of determining whether the second body movement information meets the preset standard corresponding to the third body movement information, but the action time period is different. The process of determining whether the third body motion information accords with the preset standard corresponding to the third body motion information is the same as the process of determining whether the first body motion information accords with the preset standard corresponding to the third body motion information, namely, whether the first body motion information to the third body motion information respectively accord with the preset standard corresponding to the third body motion information, the principle is the same, and the application process is different. Accordingly, a process of determining whether the third body movement information meets the preset criteria corresponding thereto will be described below.

Next to the description of the above section, it is also described here that the question asking end time value is the time period when the lie detector starts answering the question, and is also the response time of the lie detector to the current lie detecting question. And this time is also part of the reaction information. That is, the reaction information further includes: the reaction time of the lie detector before answering the current lie detection question.

Optionally, when determining whether the second physiological information meets the preset standard corresponding to the second physiological information, the method may include:

determining the physiological information change intensity value within each second preset unit time in the process of answering the current lie detection problem according to the second physiological information;

and when determining that all the physiological information intensity values in the second preset unit time meet the second preset conditions, determining that the second physiological information accords with the corresponding preset standard.

Prior to the lie detection parameter acquisition process, the person to be detected is accessed to a sensor that acquires physiological data, such as an instrument that acquires galvanic skin data. The system is used for collecting the skin electricity data of the lie detector in real time. Then, at this time of application, the main extraction is to start calculation at the moment when the lie detection question asking is finished, and ten seconds (for example, after 10 seconds) later, until the lie person answers the question and finishes the process, all the third physiological information is formed. And obtaining a maximum value H and a minimum value L from the obtained values, and calculating a difference value D of the two extreme points.

In a specific example, for example, from the 10 th second, each time a value of skin electricity is received, a difference D1 between a maximum value H1 and a minimum value L1 in a set of values over the past 2 seconds (i.e., 2 seconds in a time window) is calculated, when either of the following two conditions is satisfied: d1< = (D/10) or d1< = 0.002mV, then the current calm is determined. If one of these two conditions cannot be met within 30 seconds, the next question is entered automatically.

Further optionally, when it is determined that the preset item information in the reaction information meets the preset standard corresponding to the preset item information, the method further includes:

and classifying and labeling the answer content.

In particular, as described above. When the lie detector hears the question, a positive answer is made. I.e. giving an answer to a lie detection question. Generally, a general setup question is set as a question that can give a positive answer or a negative answer. Naturally, answers returned by lie detectors can also be categorized into two categories, positive and negative.

However, when the lie detection parameter automatic acquisition system acquires an answer, the voice of the user is converted into text. In the conversion process, a fuzzy matching method is adopted. For example, the answer to the lie detector answer is "yes", but given that the lie detector answer is likely not mandarin, a certain dialect may be present. Acquisition is for other reasons, etc., resulting in a high probability of the system being converted to "like", "persimmon", "hour", "market" or "four" when performing speech conversion, etc. Then, the presence of such answer content is automatically noted as a positive answer, as preset. If the answer is "not yes", "from time to time", "uncomfortable", "none" or "none" after the system changes the answer content into text content, it will be marked as a negative answer according to the preset.

The answer content of the lie detector is classified and marked, so that the follow-up professional can carry out statistical analysis according to the classified content and other parameters of the collected lie detector to determine whether the lie detector has a lie. For example, other parameters of the collected lie detector may include, but are not limited to, the content to be presented next.

Optionally, the response information may include, in addition to the preset item information, a response time of the person to be detected before answering the current lie-detection question, and third body action information from asking the current lie-detection question to ending the answer of the person to be detected.

The reaction time is the time before the end of the current lie detection question and the question is answered by the lie detector. The third body motion information is body motion information for a period of time from when the lie detector hears the question to when the answer ends. These parameters can all assist in determining whether a lie detector is lying.

After the current question is asked, the next question cannot be directly asked. But a certain time is needed for the lie detector to keep the mood calm, and not have too much physical actions. So as not to cause that the parameters acquired for the next problem cannot accurately determine whether the lie detector has a lie. Thus, the method also requires performing step 140, see in particular below.

Step 140, collecting first physiological information and first body motion information of a person to be detected from the moment when the person to be detected answers the current lie detection question within a preset time period.

Step 150, when it is determined that the first physiological information and the first body motion information respectively meet the preset standards corresponding to the first physiological information and the first body motion information, playing the next lie detection problem.

Specifically, whether the first physiological information accords with the preset standard corresponding to the first physiological information is judged, and the process of judging whether the second physiological information accords with the preset standard corresponding to the second physiological information is the same as that of judging whether the second physiological information accords with the preset standard corresponding to the second physiological information, and the detailed description is omitted here.

When judging whether the first body motion information accords with the preset standard corresponding to the first body motion information, the process is the same as that of determining whether the third body motion information accords with the preset standard corresponding to the third body motion information. See in particular the following:

according to the first body motion information/third body motion information, determining whether body motion information intensity values corresponding to all third preset unit time within a preset time period meet a third preset condition from the moment when a lie person answers a current lie detection problem;

when it is determined that all body movement intensity values corresponding to the third preset unit time in the preset time period meet the third preset condition, the first body movement information/third body movement information is determined to meet the preset standard corresponding to the first body movement information/third body movement information.

As described above, the principle is similar to that of judging whether the second body movement information meets the preset criterion, and the difference is only the application time period. The application time periods of the first body motion information and the third body motion information are determined to be within a preset time period from the moment that the detected lie person answers the current lie detection question. However, there is a slight difference between determining the first body movement information and determining whether the third body movement information meets the preset criteria. Determining whether the third body motion information meets the preset criteria, where the answer to the current lie detection question is "what is answered by the lie detector? "," not heard "and the like, that is, preset content. And when determining whether the first body motion information meets the preset standard, said answering the current lie detection question means that the person to be detected has given answer content for the current lie detection question, and the answer content is not the preset content.

The above process of determining whether the first body motion information/the third body motion information meets the preset standard is referred to above, and will not be repeated here.

According to the method for acquiring the response information of the lie detector, the preset voice files of the lie detection problem are played according to the preset sequence. And then collecting response information made by the lie detector in the process of processing the lie detection problem after hearing the current lie detection problem. And determining whether preset item information in the reaction information accords with a preset standard corresponding to the preset item information. If the preset criteria are met, the reaction information is stored. And collecting first physiological information and first body action information in a preset period when the detected lie personnel starts at the moment of finishing answering the current lie detection question. If the first physiological information and the first body motion information respectively accord with the preset standards corresponding to the first physiological information and the first body motion information, the next lie detection problem is started to be played, the subsequent collection and storage of the response information of the person to be detected in the process of processing the next lie detection problem are facilitated, and the operation is finished until all the preconfigured lie detection problems execute the operation. In this way, all the reaction information of the lie detector can be acquired in an automated manner. Avoiding the processes of operation, observation, evaluation and the like of the process requiring full concentration in the lie detection process of the person to be detected. Therefore, the burden of professional lie detection personnel is lightened, and the lie detection efficiency is greatly improved. Moreover, the method does not require the lie detection professional to execute corresponding operation, thereby realizing the wide popularization of the lie detection technology.
