Description

System for Managing and Providing Information Based on block chain}

The present invention relates to a blockchain-based information management and providing system, and more specifically, after encrypting medical information and product purchase information of a customer on a blockchain basis, when the customer information needs to be shared or used, the customer directly The present invention relates to a blockchain-based information management and provision system that can be utilized in various business areas while increasing the security of customer information.

As information society develops, society members perform various social activities in digital spaces like the Internet unlike in the past. For example, when trading, in the past, traders traded in physical spaces such as banks and markets, but in recent years, these trades are performed in digital spaces such as online.

As such, the most important field is information security as the social activities of social members move from physical space to digital space. This is because when a transaction is made in the digital space, not only a contract but also personal or corporate information is converted into digitization, which makes it relatively vulnerable to security.

Recently, a block chain has been proposed to connect (chain) information related to transactions in a form of a block (block) to prevent hacking of an individual's medical, human or corporate information. Blockchain breaks away from the conventional way of managing transaction information in one main server, and many share and manage all their transaction information.

Blockchain has high security, transparency and safety because all transaction information is recorded and anyone can see the record. Such blockchain was first introduced in the digital cryptocurrency called Bitcoin, but it is gradually expanding to public offices, medical institutions, banks, and the like.

However, even if blockchain is applied for information security, government agencies, medical institutions, and banks implement the information in the form of blockchain for each institution, so there is a limit in managing and using the information organically. For example, medical institutions operate in the form of corporations or individuals, and each medical institution operates independently of other medical institutions. Therefore, in order to share or use medical information such as medical records, it is necessary to request medical information from each medical institution. There is this.

In addition, since each medical institution encrypts the client's medical information in a different way, the medical information of one customer has different security, and from the perspective of the medical institution that treats the client, the client who is treating In this regard, it is difficult to know what kind of health foods have been purchased in this regard, so that quality medical services are difficult.

In addition, since medical information and product purchase information of customers are not collectively managed and operated, there are limitations in utilizing medical information and product purchase information for a plurality of customers in various fields.

2, the management system 300 of the blockchain-based information management and provision system of the present invention, the purchase information and medical care provided from the customer product purchase information server 200 and the medical information server 400 of the medical institution After the blockchain-based encryption based on the information, it is made into a database in the form of big data, which is made available to medical institutions and customers through the medical terminal 201 and the customer terminal 202.

In addition, although only the medical institution terminal 201 and the customer terminal 202 are shown in the figure, this is not fixed. For example, when an external company (an external company) who wants to use customer information (medical information and product purchase information) operated by the management system 300, access to the management system 300 to approve the use of customer information. After acquisition, customer information is available.

The management system 300 encrypts the customer information on a blockchain basis, the management operation server 350 for controlling the progress of the customer approval process for medical information requests and disclosure of the customer information, and the product purchase information server 200 And an encryption server 303 for encrypting customer information (such as product purchase information and medical records of the customer) provided from the medical information server 400, and medical data and products encrypted by the encryption server 303. First and second file storages 301 and 302 storing purchase data (customer information), and medical information and product purchase information (encrypted customer information) stored in the first and second file storages 301 and 302. The key storage server 304 stores the encryption key information stored in advance in a blockchain manner, and the customer's unique identification information (ID), and basic information of the customer corresponding to each ID (age, Gender, address, etc.), medical information A metadata server 306 for storing information on purchase information, and a search server for providing encrypted customer information in response to a request for sharing and disclosing customer information requested by the medical institution terminal 201 and the customer terminal 202. 305.

Hereinafter, each component described above will be described in detail.

The management operation server 350 encrypts the product purchase information and medical information provided from the product purchase information server 200 and the medical information server 400 based on a blockchain or corresponds to a customer information encrypted. ID or customer's 3D signature information is generated or matched. In addition, the management operation server 350 performs an approval procedure for sharing and disclosing customer information to customers according to a preset policy in response to viewing (sharing and disclosing) customer information requested from the outside, and step by step customer information. It performs a function of publishing customer information through the search server 305 by cataloging.

The encryption server 303 blocks the product purchase information of the customer provided from the product purchase information server that manufactures and sells medical information (customer's medical care and medical consultation) and health food provided from an external server operated by each medical institution. Encrypt based on chain. The medical information is a medical record for a customer, for example, image data generated from a medical device such as CT, MRI, XRAY, etc., saliva hormonal test, hair heavy metal test, immune function It may include pretest information such as a test, genetic test, organic acid test or iris test.

In addition, the product purchase information may include the period the customer purchased the product, the purchased product, age, gender, medical institution information and the like.

In addition, the encryption server 303 may automatically encrypt data by automatically updating data when a customer visits a medical institution periodically to receive medical treatment or purchase a product.

The metadata server 306 may generate a virtual file by matching encrypted medical information and product purchase information (encrypted customer information) corresponding to the unique identification information (ID) of the customer. The virtual files may be listed by combining encrypted customer information stored in the first file storage 301 and the second file storage 302 in various ways.

For example, before a customer approves the sharing and disclosure of customer information, classify and list the disease and product information by the gender and age of the customer, and then disclose detailed customer information corresponding to the list. You can do it. If the customer approves the sharing and disclosure of customer information, a list of encrypted customer information may be prepared and detailed customer information corresponding to each list may be disclosed.

When the customer or doctor of the medical institution requests the encrypted customer information corresponding to the search expression, the search server 305 discloses some or all of the customer information according to the approval of the customer, as mentioned above.

If the doctor of the medical institution requests the past disease history and purchased product information about the client currently being treated, after completing the approval process of the client, the encrypted customer information is released and displayed. Based on this customer information, medical institutions (doctors) can not only provide high-quality medical services to customers, but also can suggest customized health foods, cosmetics, and health devices for the health foods purchased by the customers.

In addition, if the customer approves the sharing and disclosure of the customer information, the customer can pay a certain point and allow the medical institution or external company that wants to use the customer information to use it as paid information, thereby making the customer information big. Can be provided in data format.

The key storage server 304 may be configured to block encryption keys in addition to medical information and product purchase information encrypted in the first and second file storages 301 and 302 or to release the encrypted customer information. You can set a chain-based password. The password for releasing the customer information serves to determine whether the customer is authorized to share and disclose the customer information in the customer authentication process. The customer approval cipher may be implemented by comparing the three-dimensional signature information of the pre-registered customer and the signature transmitted to the customer through the customer terminal in response to the customer information disclosure request.

As described above, the blockchain-based information management and providing system according to the present invention encrypts customer information, such as medical information and product purchase information, of a customer on a blockchain basis, and then a medical institution that needs to share and disclose customer information or It has the effect of providing better quality medical services to customers by opening them through the approval process of customers.

In addition, the blockchain-based information management and providing system according to the present invention, after encrypting the customer information, such as medical information and product purchase information of the customer based on the blockchain, by combining medical information and product purchase information in a variety of ways big Implementing data has the effect of using customer information in various business areas.

In addition, the blockchain-based information management and providing system according to the present invention according to the present invention, when a request for sharing or disclosure about the blockchain-based encrypted customer information, the customer can directly determine whether to approve, There is an effect to strengthen the management while increasing the security of the information.

3 is a diagram illustrating a structure of a management operation server of a blockchain based information management and provision system according to the present invention.

2 and 3, the management operation server 350 disposed in the management system 300 of the present invention, the information issuing request unit 351 for requesting the customer information of the customer from the medical institution, and the customer Request for approval of sharing and disclosure of encrypted customer information, and the customer authentication confirmation unit 352 for determining whether to approve, and the approval and sharing of the customer information from the customer authentication confirmation unit 352, if it is approved Information provider 353 for providing encrypted customer information to a medical institution or an external company to use.

The information issuing request unit 351 of the management operation server 350 is the customer authentication confirmation unit 352 when the customer has received medical treatment or medical consultation in the medical institution and the product purchase information that the customer purchased the product, After receiving approval from the customer, request the customer information from the institution or company that holds the customer information in advance.

That is, in order to encrypt and database customer information in the management system 300, the management operation server 350 may request an institution or company having customer information in advance. Such a request may be made whenever an event (EVEN) occurs that requires the use of customer information, and may allow the customer information to be provided from an external server (medical institution server or product sales server) in a batch and continuously in advance.

In order to provide customer information at the request of a medical institution or an external company, the database of medical information and product purchase information is encrypted in the form of encrypted customer information from customers who have been registered as members in the institution or company that operates the management system. The customer approval process should also be followed for the use of customer information for the database.

As such, the institution or company operating the management system has a database of customer information, and when there is a request for customer information from a medical institution or an external company, the customer approval is performed according to the approval procedure of the customer certification verification unit 352 described below. It must be obtained to provide databaseized customer information.

When there is a request for sharing and disclosure of encrypted customer information, the customer authentication confirmation unit 352 directly inquires whether the customer terminal approves the request, and determines whether the customer approves. For example, when a three-dimensional signature is stored in advance to confirm whether the customer is approved in the key storage server 304, the customer who receives the approval request signs for approval through the customer terminal, and the customer authentication verification unit To 352.

The customer certificate verification unit 352 compares the three-dimensional signature received from the customer with the customer signature stored in the key storage server 304 to determine whether the customer has approved the sharing and disclosure of the customer information.

In addition, the blockchain-based information management and provision system of the present invention in the form of publicly disclosed encrypted customer information (information stored in the first and second file storage) only when the customer has approved through the customer authentication confirmation unit 352 It can be provided to a medical institution or an external company.

The information providing unit 353 provides the information to the medical institution or an external company that has requested the customer information with respect to the customer information approved by the customer in the customer authentication confirmation unit 352.

As such, the blockchain-based information management and provision system of the present invention encrypts the customer information and then shares and discloses it to the outside only when the customer's approval is obtained, thereby maintaining high security for the customer's information. When the information is disclosed, it can only be decrypted by the customer.

4 is a view showing the structure of the customer confirmation unit of FIG.

Referring to FIG. 4, the customer confirmation server 352 of the management operation server according to the present invention includes an authentication request unit 401 for confirming whether the customer is authorized to share and disclose customer information, and the authentication request unit. A comparison unit 402 for comparing the customer signature received from the customer in response to the authentication request information sent by 401 with the customer signature stored in the key storage server 304, and by the comparison unit 402. And comparing the signatures, the decision unit 403 determines whether the customer has approved to share and disclose the customer information.

In the blockchain-based information management and provision system according to the present invention, it is important to determine whether to approve the customer because the encrypted customer information is determined only by the authentication of the customer.

In the present invention, after storing the three-dimensional signature of the customer in the key storage server 304 in advance, it is possible to determine whether the approval of the customer compared to the customer signature sent by the request of the authentication request unit 401. However, since this is not fixed, it is possible to determine whether to approve the customer's approval by inputting the authentication code issued by the certification authority.

In particular, when the 3D signature comparison method is applied to the approval of the customer, the key storage server 304 displays the pressure intensity, the signature speed, the curvature and the angle for each part when the 3D signature of the customer is stored in advance. And store the same, and classify and store the signatures of the received customers, and compare them with each other.

That is, the classification list information of the pre-stored customer's three-dimensional signature and the classification list of the received customer signature are individually compared (pressure intensity, signature speed, partial curvature, angle, etc.), and each item is 90% to 95% or more, and the average match of all items is 90% or more.

In addition, when the customer signs the customer terminal 202, a signature according to pressure intensity, signature speed, part curvature, and angle may be displayed.

In another aspect, customer terminal 202 may send a signature piece information request to management system 300. The key storage server 304 may generate a random number in response to the received signature fragment information request. The key storage server 304 divides the prestored three-dimensional signature of the customer into a plurality of signature pieces in a random direction based on a random number that generates the three-dimensional customer signature illustrated in FIG. As indicated by the dashed circle). The management system 300 can then transmit the information about the signature fragment to the customer terminal 202. The customer terminal 202 can receive the signature fragment information and display it. The customer can then assemble the signature pieces by touching the displayed signature pieces or moving each of the pieces through a separate input device. When the assembling of the signature pieces is completed, the customer terminal 202 may transmit the assembled signature information together with the assembling completion information to the management system 300. The key manager server 304 may determine whether the customer has been approved by comparing the assembled signature information received with the prestored three-dimensional customer signature.

In an embodiment, the customer has a three-dimensional customer signature to be stored in the first key storage server 304, but the pressure intensity of the touch, the signature speed, the curvature for each part on the terminal 202 according to the type of the terminal 202 For example, at least one of the angles may not be recognized, thereby solving a limitation in that the 3D customer signature may not be smooth. That is, in consideration of the above-described limitations, the customer may make the 3D customer signature be made in the form of assembling the received and displayed signature pieces.

In another aspect, the key storage server 304 may split the three-dimensional customer signature into N pieces. The N value may be set based on the complexity of the 3D customer signature. For example, the key storage server 304 may analyze the 3D customer signature to decrease the value of N when the signature is high in complexity and increase the value of N when the signature is low in complexity. Thus, despite the high complexity of the signature, many signature pieces can prevent the true customer (the customer who actually signed three-dimensional) from quickly assembling or failing to assemble the signature piece. In addition, despite the fact that the signature is not complicated, a small number of signature fragments may cause an unsuspecting customer (such as a customer who does not actually use a three-dimensional signature to steal authentication) to approximate the signature's shape and sign the signature. It is also possible to prevent problems such as authentication theft by assembling the pieces correctly.

Since the matching range for the customer approval mentioned above is for one embodiment, it is possible to compare the matching of the customer approval in various ways, and adjust the range of the degree of agreement.

As described above, the blockchain-based information management and providing system according to the present invention encrypts customer information, such as medical information and product purchase information, of a customer on a blockchain basis, and then a medical institution that needs to share and disclose customer information or It has the effect of providing better quality medical services to customers by opening them through the approval process of customers.

In addition, the blockchain-based information management and providing system according to the present invention, after encrypting the customer information, such as medical information and product purchase information of the customer based on the blockchain, by combining medical information and product purchase information in a variety of ways big By implementing the data, customer information can be utilized in various business areas.

In addition, the blockchain-based information management and providing system according to the present invention according to the present invention, when a request for sharing or disclosure about the blockchain-based encrypted customer information, the customer can directly determine whether to approve, There is an effect to strengthen the management while increasing the security of the information.
