The present invention relates to an emergency emergency treatment means, and more particularly, to an emergency treatment method and apparatus for protecting the privacy of the user even in the process of informing the disaster center that the user is in an emergency.

An emergency is a condition that threatens human life, health, and safety, such as diseases such as bird flu, traffic accidents, fires, gas explosions, and terrorism, as well as chronic diseases such as environmental pollution, aging, cancer, and diabetes. In order to solve these problems, it means a state in which a series of emergency support services must be provided by related organizations (hereinafter referred to as 'disaster centers') such as medical institutions, police stations, hospitals, and fire departments.

For example, such an activity usually occurs when a traffic accident occurs on the road, and when the accident party or witness informs the disaster center of the accident and the location of the accident, the relevant authorities are accompanied by a rescue vehicle to the emergency location. The dispatch of accident apprentices to provide support services.

However, in the past, in case of serious accidents or no witnesses, it was inevitable to notify the disaster center of the facts and the location of the accidents. There was a problem that could be received.

In the 80803 invention, a mobile communication terminal transmits information collected through an emergency heartbeat state sensor to a terminal, and the terminal transmits GPS location information and an emergency situation periodically to a base station for processing. A description of the system is described.

However, the mobile communication terminal used in the 80803 invention merely serves as an intermediate gateway, and simply collects information necessary for emergency assistance service and transmits the information to the base station for monitoring the information. There is no concern about privacy, so there is a lack of privacy protection.

That is, until now, in providing such services, personal information of an individual corresponding to privacy is stored in a database under the supervision of service providers rather than under the supervision of the individual, and is managed by the service providers. Not only did he have no control over the disclosure of his or her biometric information, he could not provide a means to realize it, and there was no way to objectively confirm that privacy was protected.

Therefore, not only the recording of the personal information of the user and the determination of the presence of an emergency can be performed under the management of the user, but also the recorded personal biometric information is only available when an emergency occurs or the user's request. There is an increasing demand for means to protect the privacy of individuals by forwarding them to disaster centers.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, in describing in detail the operating principle of the preferred embodiment of the present invention, if it is determined that the detailed description of the related known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

In addition, the same reference numerals are used for parts having similar functions and functions throughout the drawings.

Hereinafter, an emergency situation processing method according to the present invention will be described in detail with reference to FIGS. 1 and 2. FIG. 1 illustrates a configuration for schematically explaining a process of performing an emergency handling method according to an exemplary embodiment of the present invention, and FIG. 2 relates to personal authentication and encryption key generation for protecting a user's privacy. A configuration for schematically illustrating the process is shown. Of course, the emergency treatment process may include other components in addition to the above-described configuration, Figures 1 and 2 shows only the configuration necessary for convenience of description.

Referring to FIG. 1, first, biometric information and situation information (hereinafter, referred to as 'sensing information') of a user are collected from the sensor device 100 (S101). The sensor device applicable to the present invention includes a biometric sensor for detecting biometric information such as heart rate, body temperature, respiratory rate, blood sugar, blood pressure, and the like, and a situation for detecting contextual information such as an ambient temperature, pressure, and altitude of a user. A sensor. The description of the type of the biometric sensor and the situation sensor is provided to illustrate the present invention, and is not intended to limit the type of the sensor applicable to the present invention.

Next, it is determined whether or not the sensing information collected from the sensor device 100 includes an error due to an error occurring in the sensor or an error during communication with the surrounding environment (S102). This is to prevent a malfunction such as incorrectly determining that an emergency situation occurs when the sensing information is changed by an error generated on a sensor or a communication path.

Next, the collected information is encrypted and stored (S103). Encrypting the biometric information and the environmental information of the user collected from the sensor device 100 in step S103 before storing the biometric information and the environmental information, which are personal information of the user, is prevented from being publicly disclosed. In this case, the encryption key used for encryption is an encryption key given as a result of authentication of the user through an external authentication server, and thus sensing information corresponding to the privacy of the user even if the storage device storing the sensing information is leaked to the outside. Will be able to manage the outflow more efficiently. In this case, for this purpose, the encryption key is preferably stored in a separate space from the sensing information.

Hereinafter, a process of performing user authentication and issuing an encryption key through an external authentication server will be described in detail with reference to FIG. 2.

First, an authentication process for a user is requested to the external authentication server 300 (S201). This authentication process is performed when the user is the subject of the emergency situation processing method according to the present invention for the first time or the user information that is the object of the method is changed. After the authentication server 300 responds to the authentication (S202), the personal identification information and the personal identification information of the user are stored in association (S203), which is to continuously protect the privacy for the user. It is for.

Next, when the authentication server 300 receives a privacy profile from the emergency handler 200 and receives a privacy profile (S204), if the received message is encrypted, the authentication server 300 decrypts the user, and then the user of the privacy registration request. Check whether the user authenticated by the authentication server 300 (S205). The privacy registration request in step S204 is performed when a privacy profile is registered for the first time in the emergency situation processor 200 or a stored privacy profile is changed. The authentication server 300 stores the privacy profile of the user transferred in step S204 (S206), and then transmits an encryption key issued by the authentication server to the user in response to the registration request (S207).

Returning to FIG. 1 again, the biometric information and the environment information of the user stored after being encrypted are periodically transmitted to the external disaster center 400 (S105). The type, content, and range of the sensing information disclosed to the outside may be determined by the user. Is included in the privacy profile. In the present invention, the privacy profile is a summary of criteria for determining whether to disclose information corresponding to the user's privacy to the outside, such as the user's biometric information and the situation information collected from the sensor device 100. Can be set and adjusted on request. At this time, the same privacy profile for the user is also stored in the external authentication server that authenticates the user and generates an encryption key for the user, which is transmitted to the authentication server in the authentication process. The privacy profile of the user stored in the authentication server serves as the same security class criterion for the disclosure of the user's sensing information stored in the authentication server. For example, if the privacy profile security level is set to the best level, the sensing information is transmitted to the disaster center 400 only when the user is in an emergency situation, and the sensing information is not transmitted to the disaster center 400 otherwise. .

Next, by analyzing the sensing information newly collected and stored through the sensor device, it is determined whether the user is in an emergency situation. Since the criterion of whether the user is in an emergency from the sensing information depends on the respective biometric information and the type of the emergency to be expected, it cannot be defined uniquely and can be selected by the judgment of those skilled in the art. . In general, when the newly acquired sensing information through the sensor device 100 exceeds a preset threshold, for example, when the body temperature exceeds 40 degrees Celsius, the pulse rate exceeds 140 times / minute, or the newly collected sensing information is When the difference between the sensing information stored in the storage unit and the threshold value is higher than the threshold value, for example, when the respiratory rate is reduced by 40% from the user's average respiratory rate, the user may be determined to be in an emergency situation. .

As a result of the determination, if it is determined that the user is in an emergency situation, emergency information is sent to the disaster center. In this case, the emergency information transmitted to the disaster center preferably further includes additional personal information such as gender, age, weight, and location information of the user, as well as sensing information collected through the sensor device.

In addition, if it is determined that the user is in an emergency situation as a result of the determination, it is determined whether the situation in which the user is in an emergency by analyzing the situation information (S107). In this case, the emergency situation is a concept different from the emergency situation in step S106, and the biometric information and the situation information of the user who are continuously collected and stored may be lost due to a fire. Means a situation that is expected. The step S107 is to protect even in an emergency situation, and if it is determined that the user's situation is an emergency, the protection device for the storage for storing the biometric information and the situation information of the user is operated (S108). This is to protect the sensing information stored in the forensic process such as follow-up findings in case the user who is in an emergency has not reached the lifesaving despite the emergency service. The storage device for the storage device includes a mechanical device that can protect the storage device even by a physical impact so that the storage device is not damaged under any circumstances and is managed by a privacy profile.

Hereinafter, referring to FIG. 3, an emergency handler trust authority is stored in a storage device of an emergency handler 200 protected by a protection circuit through step S108 for forensic treatment such as post facto finding for a user who has not reached a lifesaving. The process of analyzing the sensing information stored in connection with 500 will be described in detail.

Referring to FIG. 3, first, when the emergency handler trust authority 500 requests the authentication server 300 to authenticate that the user has the right to access the emergency handler (S301), the authentication server 300 authenticates. A response including an encryption key for the user stored with the value is transmitted (S302).

Next, the emergency handler trust authority 500 requests the emergency handler 200 to release protection for the storage device, and provides the authentication value received from the authentication server 300 (S303). In response, the emergency handler 200 determines whether the request is a legitimate release request through the received authentication value (S304), and if it is a legitimate release request, releases the physical protection of the storage device (S305).

The trust authority 500 collects the sensing information stored in the emergency handler 200 (S306), decrypts it using the encryption key provided from the authentication server 300 (S307), and analyzes it (S308).
