Figure 1 is a block diagram illustrating the internal configuration of a false certificate identification device using biometric signals according to an embodiment of the present invention.

Referring to FIG. 1, a false card identification device (hereinafter abbreviated as 'false card identification device') using bio-signals according to an embodiment of the present invention 100 includes a direct current electrode 110, an alternating current electrode 120, and a processing unit 130. In addition, the false certificate identification device 100 may be configured to additionally include a diagnostic unit 140, depending on the embodiment.

First, the direct current electrode 110 is in contact with a part of the object 105 to obtain direct current (DC) from the object 105. In other words, the direct current electrode 110 may serve to collect the direct current component of the biological signal generated from the object 105. Here, the part of the object 105 that is in contact with the direct current electrode 110 may be the upper body of the object 105, where the direct current (DC) is statistically output in large numbers, and may be, for example, an arm or hand. .

Additionally, the alternating current electrode 120 contacts another part of the object 105 to obtain alternating current (AC) from the object 105 . That is, the alternating current electrode 120 may serve to apply a set frequency to the object 105 and collect the alternating current component of the biological signal generated from the object 105 in response to it. Here, another part of the object 105 with which the alternating current electrode 120 is in contact may be the lower body of the object 105, which easily obtains the alternating current (AC), for example, legs, feet, etc. .

In the above description, the direct current electrode 110 is in contact with the upper body of the object 105, and the alternating current electrode 120 is in contact with the lower body of the object 105. However, it is not limited to this and can be applied to any part of the object 105. It is obvious to those skilled in the art that biological signals can be obtained by contacting the direct current electrode 110 and the alternating current electrode 120 in different ways.

The frequency applied to the object 105 by the AC electrode 120 is between 1 Hz and 1 MHz, and may be 50 kHz, 100 kHz to 250 kHz. That is, the AC electrode 120 can apply a predetermined frequency to the object 105 and collect alternating current (AC) according to the application of each frequency.

The processing unit 130 determines whether the object 105 is authentic according to the biological impedance including the direct current (DC) and the alternating current (AC). That is, the processing unit 130 may calculate the biological impedance by considering the obtained direct current component and the alternating current component, and quantitatively determine whether the object 105 is false or false based on the calculated biological impedance.

In determining the false evidence, the biological reaction associated with the direct current (DC) is for determining the sweat gland secretion function of the object 105, and the biological reaction associated with the alternating current (AC) is for determining the sweat gland secretion function of the object 105. ) may be for evaluating multiple frequencies from.

In other words, the processing unit 130 can create an environment in which more quantified false positives can be determined for the object 105 by comprehensively considering items that can be evaluated through direct current (DC) and alternating current (AC). there is.

In the biological reaction that occurs in connection with the bioimpedance, the processing unit 130 determines hematuria for the object 105 when the DC conductivity with respect to the direct current (DC) decreases, and the alternating current (AC) When the AC conductivity is lowered, a concession may be determined for the object 105. That is, when determining a false case, the processing unit 130 can determine the specific symptoms of a false positive in detail by considering the fluctuation trends of DC conductivity and AC conductivity.

If the DC conductivity of the obtained direct current component is lower than the value obtained in the previous cycle and is in a downward trend, the processing unit 130 uses the DC conductivity in the upper body, which is the part of the object 105, to calculate the regression blood test score. It can be derived.

The regression blood pressure score can be calculated through a blood pressure formula in which the coefficient is changed and determined according to the age or gender of the object 105. For example, if the object is a woman over 40 years old, the coefficient is '2.644' and It can be calculated through the blood pressure formula '2.644 - 0.018 * DC conductivity', in which '-0.018' is determined.

Here, the blood deficiency formula for calculating the regression-type blood deficiency score is standardized with a questionnaire score range of 0 points (normal) to 4 points (the most severe deficiency), and the unit of DC conductivity may be μS (micro siemens).

The processing unit 130 determines whether the calculated regression-type blood ischemia score is greater than or equal to a predetermined threshold, and if so, determines the blood ischemia.

For example, if the DC conductivity collected in the previous cycle is 50 μS and the DC conductivity collected in the current cycle is 40 μS and is in a downward trend, the processing unit 130 calculates the regression score using the DC conductivity of 40 μS in the current cycle. By entering it into the food intake formula, the regression score '1.924' can be calculated.

Afterwards, the processing unit 130 can confirm blood ischemia for the object 105 as the calculated regression score '1.924' exceeds the threshold '1.8'.

Depending on the embodiment, the ischemia determination device 100 may further include a diagnostic unit 140 that more clearly diagnoses the symptoms of the object 105 confirmed to have hematoma ischemia.

In other words, if the DC conductivity is lower than the specified detailed threshold, the diagnostic unit 140 can diagnose the symptoms of hemorrhage as 'symptoms of frequent cramping' or 'symptoms of dull hair.'

In the above 'example where the DC conductivity collected in the current cycle is 40μS', the diagnostic unit 140 compares the DC conductivity of 40μS with the detailed threshold value of 45μS, and as the DC conductance of 40μS is lower than the detailed threshold value of 45μS, , it is possible to diagnose the specific symptom of blood ischemia, ‘symptoms of cramping’.

In another embodiment, when the AC conductivity of the AC component obtained is lower than the value obtained in the previous cycle and is in a downward trend, the processing unit 130 performs AC conductivity according to the AC conductivity in the lower body, which is the other part of the object 105. Using impedance, a regression concession score can be derived.

The regression concession score can be calculated through a concession formula in which the coefficient is determined by changing depending on the age or gender of the object 105. For example, if the object is a woman over 40 years old, the coefficient is '-1.690'. and '0.010' can be calculated through the concession formula '-1.690 + 0.010 * AC impedance'.

Here, the concession formula for calculating the regression concession score has a standardized questionnaire score range of 0 points (normal) to 4 points (the most severe defect), and the unit of AC impedance may be Ω.

The processing unit 130 determines whether the calculated regression concession score is more than a predetermined threshold, and if it is more than the threshold, it can be confirmed with the concession certificate.

For example, if the AC impedance of the previous cycle is 300Ω and the AC impedance of the current cycle is 340Ω, the processing unit 130 inputs the AC impedance of the current cycle, 340Ω, into the concession formula that is the calculation formula for the regression concession score, and returns The formula concession score '1.71' can be calculated.

Afterwards, the processing unit 130 can confirm the concession for the object 105 as the calculated regression concession score '1.71' exceeds the threshold '1.5'.

Depending on the embodiment, the false certificate determination device 100 may more clearly diagnose the symptoms of the object 105 confirmed as a concessionary certificate through the diagnosis unit 140.

That is, if the AC impedance is higher than the set detailed threshold, the diagnosis unit 140 selects among the symptoms of concession syndrome, 'a symptom of preferring warm water even when thirsty' or 'a symptom of liking warm water when it is cold'. ' can be diagnosed.

In the above-mentioned 'example of the case where the AC impedance of the current cycle is 340Ω', the diagnosis unit 140 compares the AC impedance 340Ω with the detailed threshold value '320Ω', and as the AC impedance is higher than the detailed threshold value, the specific The symptom of yangheojeung can be diagnosed as ‘a symptom of preferring warm water even when thirsty.’

Depending on the embodiment, the processing unit 130 may determine at least one of the sympathetic nerve and parasympathetic nerve hyperactivity as a result of HRV through PPG (Photo Plethysmography), pressure pulse wave, and ECG (Electrocardiography) measurement to determine the autonomic nerve reactivity of the object 105. By further considering, it is possible to re-determine whether the object 105 is false.

Here, PPG interprets the activity of the heart using an optical device, and may be a method of detecting the heart rate of the object 105 by detecting the flow of blood by passing light. Additionally, a pressure pulse wave may refer to a wavelength through which blood propagates by applying pressure to generate an artery in a specific part of the object 105.

ECG refers to a general electrocardiogram, and can refer to a method of interpreting the electrical activity of the heart at a given time.

HEV (Heart Rate Variability) refers to the slight difference between one heart beat cycle and the next. HRV is determined by the influence of the autonomic nervous system and is related to the interaction between the sympathetic and parasympathetic nervous systems. Through this interaction, heart rate can change according to changes in the internal/external environment. For example, in healthy people, changes in heart rate appear large and complex, but in disease or stress conditions, the complexity may appear significantly reduced.

That is, the processing unit 130 further considers various types of signals obtained from the object 105 in addition to the determination by the direct current and alternating current components collected through the electrodes to more accurately determine the authenticity of the object 105. You can.

In another embodiment, the processing unit 130 irradiates the skin with near-infrared rays and mid-infrared rays to confirm changes in blood flow, further considers the absorbance according to irradiation of the near-infrared rays and mid-infrared rays, and detects a false light for the object 105. can be judged.

That is, the processing unit 130 may determine whether the object 105 is false by additionally considering the degree of light absorption in the skin according to changes in blood flow flowing through the object 105.

For example, if the change in blood flow is small and the light absorbance is maintained constant, the processing unit 130 can determine the healthy state of the object 105 without false evidence.

According to one embodiment of the present invention, by quantifying the degree of hernia using a non-invasive bio-signal response, a method and method for determining hernia using bio-signals enable quantitative determination of hernia based on bio-signals in clinical practice. Devices can be provided.

In addition, according to one embodiment of the present invention, by quantifying hypocrisy using objective and easy non-invasive biosignals, subjective ambiguity of the questionnaire in clinical practice can be resolved and this questionnaire can be replaced.

In addition, according to one embodiment of the present invention, through the results of clinical research, a significant correlation between bio-signal indicators and the degree of hernia can be obtained, thereby ensuring the accuracy of the diagnosis of hernia.

Figure 2 is a diagram illustrating the correlation between false evidence questionnaire scores and measurement parameters according to the present invention.

Figure 2a illustrates the correlation with the blood ischemia questionnaire score when DC response conductance (Conductance) is adopted as the measurement parameter.

Figure 2a shows a correlation chart showing that as Conductance (Right Foot) increases, the blood ischemia questionnaire score (blood ischemia score) decreases proportionally.

The simple linear regression model to calculate the regression type blood weakness score can be expressed in the form =β+β ₁ *+ε, and in the case of a female diabetic patient, "blood weakness score (average) = 2.644 - 0.018*ESC(Right foot) "It can be expressed as:

The blood level score (average) ranges from 1 to 4, and for example, has a 4-point scale (average value based on the original scale) out of a total of 8 questions. The survey score range can be standardized from 0 (normal) to 4 (severe false symptoms).

Figure 2b illustrates the correlation with the concession questionnaire score when 50 kHz response impedance (Impedance) is adopted as the measurement parameter.

Figure 2b shows a correlation in which the concession survey score (concession score) increases proportionally as Impedance (50 kHz Right Hand) increases.

The simple linear regression model to calculate the regression concession score can be expressed in the form =β+β ₁ *+ε, and in the case of a female diabetic patient, "concession score (average) = -1.690 + 0.010*Impedance(50kHz Right hand)".

The concession score (average) exists between 1 and 4 points, and for example, has a 4-point scale (average value based on the original scale) out of a total of 8 questions. The survey score range can be standardized from 0 (normal) to 4 (severe false symptoms).

Figure 3 is a diagram illustrating the significant correlation between biometric signals and false positive identification according to the present invention.

In the present invention, instead of the questionnaire that was conducted when determining existing Qi Heojeung, Blood Heojeung, Yin Heojeung, and Yang Heojeung, the judgment of Heoheung symptoms is based on the existing questionnaire by scoring based on bio-signals measured by applying direct/alternating current to the body. It can be done more objectively and more easily.

For this purpose, the hernia determination device 100 measures electrical conductivity by directly applying direct current or alternating current to the extremities of the human body in relation to yangheojeung and blood isheria, or measures heart rate/electrocardiogram with infrared rays irradiated directly to the skin, thereby detecting hernia. Can be diagnosed and measured.

Figures 3a and 3b are diagrams showing the correlation between impedance and concession symptoms.

First, Figure 3a is AC impedance according to AC conductivity, and is a graph showing the correlation between '50 kHz right hand' and the concession symptom 'I drink warm food rather than cold water even when I am thirsty.'

As shown in FIG. 3A, for an impedance of '300', the hesitancy determination device 100 may calculate the degree of the hesitancy symptom 'I drink warm food rather than cold water even when I am thirsty' as low as '1.8'.

Additionally, Figure 3b is an AC impedance according to AC conductivity and is a graph showing the correlation between '50kHz right hand' and the Yangheo symptom 'I get cold a lot and like warm things'.

As shown in FIG. 3B, the hypothetical symptom determination device 100 can calculate the degree of the concession symptom 'I get cold a lot and like warm things' relatively high as '3.0' for the impedance '350'.

In other words, the hernia diagnosis device 100 can quantify and display the diagnosis of hernia through bio-signals as a numerical value by increasing the possibility of a specific concession symptom in direct proportion to the size of the AC impedance according to AC conductivity.

Figures 3c and 3d are diagrams showing the correlation between electrical conductivity and symptoms of hemorrhage.

Figure 3c is an electrical conductivity graph to show the correlation between 'right foot' and the blood ischemia symptom 'feeling cramps easily'.

As shown in FIG. 3C, the ischemia determination device 100 can calculate the degree of the blood isher symptom 'cramping easily' as low as '1.2' for an electrical conductivity of '80.00'.

In addition, Figure 3D is a graph showing the correlation between the electrical conductivity diagram, 'right foot', and the blood ischemia symptom 'hair is dull'.

As shown in FIG. 3D, the ischemia determination device 100 can calculate the degree of the hematocrit symptom 'hair is dull' as relatively high as '2.4' for an electrical conductivity of '40.00'.

In other words, the ischemia determination device 100 can display the diagnosis of hematomas through biological signals by quantifying them as numbers by lowering the possibility of specific hematoma symptoms in inverse proportion to the size of electrical conductivity.

Hereinafter, in FIG. 4, the work flow of the authentication device 100 according to embodiments of the present invention will be described in detail.

Figure 4 is a flowchart showing the sequence of a false certificate identification method according to an embodiment of the present invention.

The authentication method according to this embodiment can be performed by the authentication device 100 described above.

First, the authentication device 100 acquires a direct current (DC) from the object through a direct current electrode in contact with a part of the object (410). Step 410 may be a process of collecting direct current components of bio-signals generated from an object. Here, the part of the object that is contacted with the direct current electrode may be the upper body of the object through which the direct current (DC) is statistically output in large numbers, and may be, for example, an arm or hand.

Additionally, the authentication device 100 obtains an alternating current (AC) from the object through an alternating current electrode in contact with another part of the object (420). Step 420 may be a process of applying a set frequency to an object and collecting alternating current components of bio-signals generated from the object in response. Here, another part of the object with which the alternating current electrode is in contact may be the lower body of the object, which easily obtains the alternating current (AC), for example, legs, feet, etc.

The frequency applied to the object by the alternating current electrode is between 1Hz and 1MHz, and may be 50kHz, 100kHz to 250kHz. That is, the AC electrode can apply a predetermined frequency to the object and collect alternating current (AC) according to the application of each frequency.

In addition, the authentication device 100 determines whether an object is authentic according to bioimpedance including the direct current (DC) and the alternating current (AC) (430). Step 430 may be a process of calculating biological impedance by considering the obtained direct current component and alternating current component, and quantitatively determining whether the object is false or false based on the calculated biological impedance.

In determining the authenticity, the biological response associated with the direct current (DC) is to determine the sweat gland secretion function of the object, and the biological response associated with the alternating current (AC) is to determine multiple frequencies from the object. It may be for evaluation purposes.

In other words, the authentication device 100 comprehensively considers items that can be evaluated through direct current (DC) and alternating current (AC), and creates an environment in which a more quantified authentication decision can be made for an object. .

In the biological reaction occurring in relation to the bioimpedance, the ischemia determination device 100 determines hemorrhage for the object when the DC conductivity with respect to the direct current (DC) decreases, and When the AC conductivity is lowered, a concession can be determined for the object. In other words, when determining a false case, the false positive case determination device 100 can determine specific symptoms of a false positive in detail by considering the fluctuation trends of DC conductivity and AC conductivity.

If the DC conductivity of the obtained direct current component is lower than the value obtained in the previous cycle and is in a downward trend, the hernia determination device 100 uses the DC conductivity in the upper body, which is the part of the object, to derive a regression-type blood hernia score. can do.

The regression blood pressure score can be calculated through a blood pressure formula in which the coefficient is determined by changing the coefficient depending on the object's age or gender. For example, if the object is a woman over 40 years old, the coefficients are '2.644' and '-0.018.' ' can be calculated through the blood pressure formula '2.644 - 0.018 * DC conductivity'.

The ischemia determination device 100 determines whether the calculated regression-type blood ischemia score is greater than or equal to a predetermined threshold, and if it is greater than the predetermined threshold, it can confirm the blood ischemia.

For example, if the DC conductivity collected in the previous cycle is 50 μS and the DC conductivity collected in the current cycle is 40 μS and is in a downward trend, the ischemia determination device 100 determines the DC conductivity of the current cycle as 40 μS and the regression type hematocrit score. You can calculate the regression score '1.924' by entering the blood pressure formula, which is the calculation formula of .

Afterwards, the ischemia determination device 100 can confirm the hematomatosis for the object as the calculated regression hematocrit score '1.924' exceeds the threshold '1.8'.

Depending on the embodiment, the ischemia determination device 100 may more clearly diagnose the symptoms of an object confirmed to have hematoma ischemia.

In other words, if the DC conductivity is lower than the specified detailed threshold, the ischemia determination device 100 can diagnose the symptoms of hematochezia as 'symptoms of frequent cramping' or 'symptoms of dull hair.'

In the above-mentioned 'example when the DC conductivity collected in the current cycle is 40μS', the false identification device 100 compares the DC conductance of 40μS with the detailed threshold value of 45μS, and determines that the DC conductance of 40μS is lower than the detailed threshold value of 45μS. Accordingly, the specific symptom of blood ischemia, ‘symptoms of frequent cramps’, can be diagnosed.

In another embodiment, when the AC conductivity of the AC component obtained is lower than the value obtained in the previous cycle and is in a downward trend, the false positive determination device 100 determines the AC impedance according to the AC conductivity in the lower body, which is the other part of the object. Using , the regression concession score can be derived.

The regression concession score can be calculated through a concession formula in which the coefficient is determined by changing the coefficient depending on the age or gender of the object. For example, if the object is a woman over 40 years old, the coefficients are '-1.690' and '0.010. ' can be calculated through the concession formula '-1.690 + 0.010 * AC impedance'.

The certificate determination device 100 determines whether the calculated regression concession score is greater than or equal to a predetermined threshold, and if it is greater than or equal to the predetermined threshold, the certificate of concession can be confirmed.

For example, if the AC impedance of the previous cycle is 300Ω and the AC impedance of the current cycle is 340Ω, the authenticity determination device 100 inputs the AC impedance of the current cycle, 340Ω, into the concession formula that is the calculation formula for the regression concession score. , the regression concession score '1.71' can be calculated.

Afterwards, the certificate determination device 100 can confirm the concession certificate for the object as the calculated regression concession score '1.71' exceeds the threshold '1.5'.

Depending on the embodiment, the false certificate determination device 100 may more clearly diagnose the symptoms of an object confirmed as a false certificate.

In other words, if the AC impedance is higher than the set detailed threshold, the hesitancy determination device 100 selects among the symptoms of the hesitancy, 'a symptom of preferring warm water even when thirsty' or 'a symptom of liking warm water when it is cold'. It can be diagnosed based on symptoms.

In the above-mentioned 'example of the case where the AC impedance of the current cycle is 340Ω', the false identification device 100 compares the AC impedance 340Ω with the detailed threshold value '320Ω', and according to the AC impedance is higher than the detailed threshold value, A specific symptom of yangheojeung can be diagnosed, ‘a symptom of preferring warm water even when thirsty.’

Depending on the embodiment, the ischemia determination device 100 determines at least one of sympathetic and parasympathetic nerve hyperactivity as a result of HRV through PPG (Photo Plethysmo Graphy), pressure pulse wave, and ECG (Electrocardiography) measurements for determining the autonomic nerve reactivity of the object. With further consideration, the authenticity of the object can be re-judged.

Here, PPG interprets the activity of the heart using an optical device, and may be a method of detecting the heart rate of an object by detecting the flow of blood by passing light. Additionally, a pressure pulse wave can refer to a wave that blood propagates by applying pressure to create an artery in a specific part of an object.

ECG refers to a general electrocardiogram, and can refer to a method of interpreting the electrical activity of the heart at a given time.

HEV (Heart Rate Variability) refers to the slight difference between one heart beat cycle and the next. HRV is determined by the influence of the autonomic nervous system and is related to the interaction between the sympathetic and parasympathetic nervous systems. Through this interaction, heart rate can change according to changes in the internal/external environment. For example, in healthy people, changes in heart rate appear large and complex, but in disease or stress conditions, the complexity may appear significantly reduced.

In other words, the authentication device 100 can more accurately determine whether an object is false by further considering various types of signals obtained from the object along with the discrimination based on the direct current and alternating current components collected through the electrodes.

In another embodiment, the false certificate determination device 100 irradiates the skin with near-infrared rays and mid-infrared rays to confirm changes in blood flow, and further considers the absorbance according to the irradiation of the near-infrared rays and mid-infrared rays to reconsider the false certificate for the object.

In other words, the false identity determination device 100 may determine whether an object is false by additionally considering the degree of light absorption in the skin according to changes in blood flow flowing through the object.

For example, if the change in blood flow is small and the light absorbance is maintained constant, the false positive determination device 100 can determine the healthy state of the object without false negative.
