[0006] It is preferable that the security system be provided with a plurality of vital meters each measuring a different type of vital value, and the difference used to determine whether to remove the protection is the sum of the deviations between each vital value measured by the plurality of vital meters and each corresponding vital reference value.

[0007] In addition, in the security system, the deviation used to determine whether to remove the protection is preferably a normalized deviation.

[0008] It is also preferable that the security system further comprises a reporting means for reporting to the outside when the protection release restricting means restricts the release of protection of the target.

[0009] In addition, in the security system, it is preferable that the vital meter measures at least one of the human vital signs including heart rate, respiratory rate, body temperature, blood pressure, galvanic skin response, nystagmus, oxygen saturation, blood sugar level, and electrocardiogram.

[0010] In addition, the security system may be such that the plurality of vital meters measure two or more types of vital values ​​selected from a human heart rate, respiratory rate, body temperature, blood pressure, galvanic skin response, nystagmus, oxygen saturation, blood glucose level, and electrocardiogram.

[0011] In addition, the object to be protected in the security system is preferably a safe, a vault, a depository, a residence, a device, a vehicle, a computer system, or a network system.

[0012] In addition, the object to be protected in the security system may be electronic data stored on an electronic storage medium.

[0017] [Figure 1] 1 is an exemplary block diagram illustrating a security system according to one embodiment of the present invention. [Figure 2] 2 is a flowchart illustrating an operation method of the security system of FIG. 1. DETAILED DESCRIPTION OF THE INVENTION

[0018] A security system 10 according to a preferred embodiment of the present invention will now be described with reference to the drawings. As shown in Fig. 1, the security system 10 comprises protection means 11 that protects an object 100 from external access, protection removal means 12 that removes the protection, and authentication means 13 that authenticates access rights. The security system 10 further comprises a vital meter 14 that measures a person's vital signs, a memory 15 that stores reference vital signs of specific users who are permitted to access the protected object 100, and protection removal restriction means 16 that restricts removal of protection of the protected object 100.

[0019] The security system 10 can provide security for various types of objects 100. The objects 100 protected by the security system 10 can be, for example, safes, vaults, storage rooms, or residences.

[0020] An example will be described in which the protected object 100 is a safe 101. For example, safe 101 is usually provided with a locking mechanism 111 as protection means 11 for locking the opening and closing of door 101A. Locking mechanism 111 has, for example, a function for locking the opening and closing of door 101A of safe 101. Safe 101 also has protection release means 12 for unlocking door 101A. Protection release means 12 is incorporated into locking mechanism 111 (protection means 11), or is configured as an electronic circuit that cooperates with locking mechanism 111. Authentication means 13 is configured as a means for authenticating that the user is authorized to unlock safe 101.

[0021] The authentication means 13 can usually authenticate a user by inserting a predetermined key or by using an IC card or the like that stores ID information that proves access rights to the object 100. User authentication by the authentication means 13 may also require the user to enter dialing or a password (PIN number) (multi-stage security). Once it has been authenticated that the user is authorized to access, the protection removal means 12 can remove protection from the object 100, i.e., unlock the door 101A of the safe 101.

[0022] The object 100 protected by the security system 10 may be a device or equipment such as a facility operating in a production plant, a work machine operating in the field, or a military weapon, or may be a vehicle such as an automobile, railroad car, or aircraft.

[0023] If the protected object 100 is a device as described above, the protection means 11 can restrict power-on, start-up, operation, etc. by a person without the authority to operate it. Also, if the protected object 100 is a vehicle as described above, the protection means 11 can restrict boarding, engine start, handling, etc. by a person without the access right. It can be easily understood that the protection release means 12 for such a device or vehicle is a means for releasing the restriction on these operations by a specific user with the access right.

[0024] Furthermore, the target 100 protected by the security system 10 may be, for example, a computer system or a network system such as a local area network (LAN). When the target 100 to be protected is a computer system or a network system as described above, the protection means 11 is understood to be processing means that restricts unauthorized persons from logging in to the system, intrusion, and launching and operating application programs. The protection removal means 12 in this example is also understood to be processing means that permits access to the system when a user is authenticated as being authorized to access.

[0025] Furthermore, the target 100 protected by the security system 10 may be, for example, electronic data stored in an electronic storage medium. Examples of the electronic data to be protected include personal information, collected data, experimental data, trained AI models, big data, and trade secret information. When the target 100 to be protected is the above-mentioned electronic data, the protection means 11 is a processing means that restricts operations such as reading (viewing), rewriting (editing), deleting, copying, and moving of the electronic data by persons without access rights. In this example, the protection removal means 12 is a processing means that permits each operation based on the access rights of an authenticated user.

[0026] Furthermore, the object 100 protected by the security system 10 may be, for example, the operation of a computer process. Examples of the operation of a computer process to be protected include electronic transactions in online banking, purchasing products on an electronic commerce site (EC site), electronic signatures or user authentication for receiving various cloud services, and the issuance of one-time passwords for such user authentication. When the object 100 to be protected is the operation of a computer process as described above, the protection means 11 is processing means that regulates the activation and operation of the computer process. In this example, the protection release means 12 is processing means that allows the computer process to be performed when the authority to perform the computer process is confirmed.

[0027] Conventional security systems are based on the premise that only specific users with access rights have the key to unlock the door or know the password information, etc. On the other hand, this means that anyone who has the specified key or knows the password information, etc., can unlock the door.

[0028] On the other hand, the present security system 10 is characterized by comprising a vital meter 14 that measures a person's vital signs, a memory 15 that stores reference vital signs of specific users who are permitted to access the protected object 100, and protection removal restriction means 16 that restricts removal of protection of the protected object 100. The protection removal restriction means 16 described below may be incorporated into the protection removal means 12, or may be a device independent of the protection removal means 12.

[0029] The security system 10 measures the vital value of a person attempting to access a protected object 100 using a vital meter 14. The protection release restriction means 16 restricts the release of protection of the protected object 100 when the difference Dif between the vital value Vm measured by the vital meter 14 and the vital reference value Vr stored in the memory 15 exceeds a predetermined range.

[0030]

number

[0031] Here, the reference vital value Vr stored in memory 15 is preferably determined for each specific user who is permitted to access. Specifically, multiple sample vital data can be obtained from a specific user, and the average or median of the sample data can be determined as the reference vital value Vr. The determined reference vital value Vr is associated with the ID information of the user from whom the sample was obtained and stored in memory 15. That is, the reference vital value Vr of the corresponding user can be read from memory 15 based on the ID information authenticated by authentication means 13.

[0032] The security system 10 according to this embodiment acquires vital data that reflects changes in a person's psychological or emotional state and uses that data to protect the target 100. For example, a person attempting to steal something stored in a safe 101 will likely experience a higher-than-normal heart rate when opening the safe 101. Alternatively, a person who is forced to unlock the safe 101 under threat from another person will likely experience an increase in heart rate and blood pressure. The security system 10 is configured to capture such a person's psychological state from the vital data and determine whether to release protection for the protected target 100 accordingly. This allows the security system 10 to provide safer protection than ever before.

[0033] The security system 10 may further include a reporting means 17. The reporting means 17 is configured as a means for reporting, transmitting, or notifying an external party (e.g., the owner, a management department, or a security company) when vital data acquired from a person attempting to access the target 100 indicates an abnormality relative to a reference value. By providing the security system 10 with a reporting means 17 that notifies an external party of such an abnormality, it can, for example, lead to the arrest of the perpetrator and contribute to preventing an attempted criminal act. Furthermore, when the vital data indicates an abnormality, a false one-time password (an invalid secondary password) may be issued and provided. This can buy time until the police or other authorities arrive.

[0034] Furthermore, the notification means 17 may be configured to notify a third party and / or request consent each time protection is released, even if the vital data is normal. This allows a third party to monitor the release of protection for the protected object 100, effectively preventing damage from spreading due to repeated unauthorized access. Furthermore, the record of the notification from the notification means 17 can be kept as evidence to prove that fraud has occurred.

[0035] The vital meter 14 provided in the security system 10 preferably measures at least one of the following vital values: heart rate, respiratory rate, body temperature, blood pressure, galvanic skin response, nystagmus, oxygen saturation, blood glucose level, or electrocardiogram. Each of these vital data is biological information that reflects changes in a person's psychological or emotional state.

[0036] For example, a photoplethysmogram (PPG) sensor can measure heart rate and respiratory rate by shining light onto human skin, and can estimate blood pressure using an AI (artificial intelligence) algorithm based on the heart rate and respiratory rate data.

[0037] For example, a pulse oximeter can measure arterial blood oxygen saturation (SpO2) and pulse rate by shining light onto a person's fingertip.

[0038] For example, a non-contact thermometer can measure body temperature by detecting the amount of infrared radiation emitted by the skin.

[0039] For example, the amount of sweating on the skin can be measured by galvanic skin response (GSR), which is a method of passing a weak current between a pair of electrodes attached to the palm or fingertips and measuring the change in electrical resistance between the electrodes.

[0040] Nystagmus can be measured, for example, by capturing eye movements with a video camera and subjecting the moving images to image analysis processing.

[0041] Blood glucose levels can be measured by non-invasive blood glucose measurement techniques, which irradiate capillaries with near-infrared light or mid-infrared laser light and analyze the glucose absorption spectrum when the infrared laser light passes through the capillaries.

[0042] An electrocardiogram (ECG) monitor can monitor the electrocardiogram (electrocardiogram). By analyzing the electrocardiogram waveform obtained by the ECG monitor, it is possible to quantitatively indicate not only the heart rate but also abnormalities such as irregular pulse.

[0043] If a vital sign monitor is used, most of the above vital data can be obtained simultaneously.

[0044] The security system 10 according to this embodiment may be provided with a plurality of vital meters 14 for measuring different types of vital values. Preferably, two or more vital meters 14 measure two or more types of vital values ​​selected from, for example, a human's heart rate, respiratory rate, body temperature, blood pressure, galvanic skin response, nystagmus, oxygen saturation, blood glucose level, and electrocardiogram.

[0045] In this embodiment, the protection removal restriction means 16 compares each vital value Vm1, Vm2, ... measured by each vital meter 14 with each corresponding vital reference value Vr1, Vr2, ... stored in the memory 15. Then, the protection removal restriction means 16 restricts removal of protection of the protected target 100 when at least one of the differences Dif1, Dif2, ... exceeds a predetermined range.

[0046]

number

[0047] The protection removal restriction means 16 may also calculate absolute values ​​Div1, Div2, etc. of deviations between each vital value Vm1, Vm2, etc. measured by each vital meter 14 and the corresponding vital reference value Vr1, Vr2, etc., and restrict removal of protection for the protected subject 100 if the sum SumDiv of these deviations exceeds a predetermined range. Here, the absolute values ​​Div1, Div2, etc. of deviations are preferably statistically normalized standard deviations. In this embodiment, the vital reference values ​​Vr1, Vr2, etc., the corresponding standard deviations SDiv1, SDiv2, etc., and ID information of the user whose vital data sample was obtained are associated and stored in the memory 15.

number

number

[0048] Furthermore, the protection release restriction means 16 may infer the psychological state of a person attempting to access the target 100 via an AI model based on multiple types of vital data. By analyzing more types of vital data as input variables using a trained classification model, more detailed psychological states of the person can be clustered, such as guilt, impatience, tension, anger, fear, etc. The protection release restriction means 16 can determine whether to release protection for the protected target 100 based on the psychological state inferred via the AI ​​model. This allows the security system 10 to achieve both safety and convenience.

[0049] Case 1: Robbery and murder prevention When a person opens a safe, a vital meter can be used to determine whether the person's psychological state is normal or abnormal. If an abnormality is detected based on vital data, a third party can be notified, sending an SOS to the police, security companies, or relatives. This allows for rapid response and leads to the capture of the culprit. Furthermore, providing false unlocking information can delay the safe's opening, preventing the culprit from committing murder. Furthermore, by simultaneously operating security cameras, the recordings can be kept as evidence to prove that foul play has occurred.

[0050] Case 2: Theft prevention For example, if an abnormality is detected using vital data stored in the safe, a third party can be notified and a false password or other unlocking information can be provided to buy time for the perpetrator to commit a crime. It is also desirable to activate security cameras as soon as an abnormality is detected. Records of such incidents can be kept as evidence to prove that fraud or criminal activity has occurred.

[0051] Case 3: Prevention of bank transfer fraud, blackmail, and extortion When transferring money at a bank ATM, a vital meter can be used to determine whether a person's psychological state is normal or abnormal. If an abnormality is detected using vital data, it can prevent forced and illegal transfers. In addition, by reporting, transmitting, and notifying a third party, it can lead to the early capture of the perpetrator, as in the case above. It is also possible for a third party, such as a relative, to intervene when transferring money.

[0052] Case 4: Preventing drunk driving and car theft When starting a car engine, a vital sign meter can be used to determine whether a person's psychological state is normal or abnormal. By determining whether a person's psychological state is normal or abnormal, a means can be provided to eradicate drunk driving. Furthermore, determining whether vital signs are normal or abnormal can also help prevent car theft. Furthermore, by activating and linking the GPS (Global Positioning System), it is possible to speed up the arrival of police and the owner at the scene.

[0053] Case 5: Prevention of unauthorized access The source of access rights to a computer system can be determined using a vital meter. By determining whether an accessing person's psychological state is normal or abnormal, unauthorized access can be prevented.

[0054] Case 6: Prevention of embezzlement through inflated billing When billing suppliers, etc., vital data is used to determine whether the billing is normal or abnormal, and approval is sought from higher-ups. This prevents inflated billing and embezzlement by employees.

[0055] Case 7: Confirming the survival and health of people living alone Data from vital signs installed on doors or storage areas of single-person residences is transmitted to a third party, allowing relatives to check on the safety of their parents who live alone. [Explanation of symbols]
