Description

Medical treatment information service system through the internet web site and its operation method

The present invention relates to a medical care information service through a computer communication network, specifically, to integrate medical institutions nationwide to store medical images (photographed with an image diagnosis device) and the findings of a doctor through a computer communication network, and to restrict time and space. The present invention relates to a medical information service system and a method of operating the same through an internet web site that can be used to query patient's medical information anytime, anywhere.

In more detail, medical images that computer users want to transmit, such as X-rays, as well as medical images taken with advanced imaging devices such as CT, MR, DSA, and ultrasound, are digital images instead of films. By transferring to each PC, the computer user can access the web server and enter the user's password key and the patient's password key so that the patient's medical images can be easily retrieved and transmitted, allowing patients to receive prompt and accurate treatment. The present invention relates to a medical care information service system and an operation method through an internet web site.

Currently, the Internet is in the spotlight as a huge and efficient information storage medium and information providing medium connected with numerous computer networks all over the world, and as the number of Internet-connected networks and the number of Internet users increase rapidly, various uses of the Internet are rapidly spreading. have.

In general, clinical diagnosis is a big part of the treatment of patients, and the development of modern medicine has helped to make accurate clinical diagnosis, and its dependence will continue to increase. In particular, the help of medical imaging equipment, such as CT and MRI, has become as essential as a doctor's stethoscope.

Conventional medical services, however, use medical imaging equipment to photograph patients' abnormalities, print them on a film, write radiologists, and then send a film and a statement to the patient's doctor to make a clinical diagnosis. The lack of time and manpower contributes to inefficient resource management, which in no way helps the hospital's finances, but also does not allow the patient to receive prompt and accurate treatment.

In addition, in Korea, X-ray photographed films are to be kept for five years, and each hospital stores X-ray films of each patient for each patient. However, as the size of the hospital grows and the number of patients increases, the number of X-ray films to be stored increases, and waste of space and manpower required for storing and managing the films is severe, resulting in a considerable problem. For example, an increase in the number of retakes due to poor storage of bad films and films, medical disputes due to film loss, and waste of time and labor required to find stored films.

In modern society, science and technology have been developed due to human needs, and in the medical field, a system for providing medical services using computer and data communication technology has been studied.

In order to solve these problems, a computer communication network is installed throughout the hospital, and all X-ray films are converted into digital data, made into a database, and then stored in a large storage medium. A system (called PACS; Picture Arching Communication System) that allows the user to recall X-ray images of the recent years has been introduced.

However, these systems require large storage media and computer networks, which can be expensive and manpower not only for installation but also for maintenance. Therefore, it is difficult to employ in small and medium-sized hospitals and private hospitals. In addition, the medical service system that integrates hospitals all over the country is urgently needed to achieve medical image transmission between remote hospitals.

In addition, in Korea, the polarization of hospitals is prominent, so doctors prefer state-of-the-art medical facilities and large hospitals with specialists in many fields, and people living in geographically remote or deteriorated farming and fishing villages have high human rights despite the basic human rights. Not only are they unable to receive services, but the erroneous health care system is a significant problem.

Therefore, there is a need for a new type of model that eliminates the disadvantages of conventional medical services.

Accordingly, the present invention has been made to solve the above-mentioned problems, and when the doctor's encryption key and the patient's encryption key is input to the web server through a computer communication network, the patient's medical information is uploaded and downloaded regardless of the region. Medical information service system and its operation method through internet web site that can be loaded to enable medical information nationwide to share medical information and facilitate medical information exchange so that patients can receive high quality medical services. The purpose is to provide.

Another object of the present invention is to generate a cryptographic key using a doctor's license number and the patient's resident registration number and to perform two authentication processes through the input of the doctor and the patient's encryption key to confirm the patient's medical records. It is an object of the present invention to provide a medical information service system and an operation method through an internet web site which thoroughly prevents the patient's medical records from being abused by thorough security.

Another object of the present invention is to enable the transmission of medical images such as X-rays, MRI, CT, etc. of the patients to the web server using a computer communication network and to check the medical images transmitted to the web server by entering the patient's encryption key It aims to provide a medical information service system and an operation method through an internet web site that enables a quick and accurate clinical diagnosis without construction restrictions.

In addition, the first and second authentication steps for receiving the service of the present invention are characterized in that the user's doctor's license number and password and the patient's social security number and password generated using the encryption key.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic diagram of a medical care information service system and its operation method through an Internet web site of the present invention.

First, digital images such as CT and MRI are obtained through a digital imaging device. Digital imaging devices such as CT and MRI acquire images using a protocol called DICOM 3.0, a medical imaging standard published by ACR-NEMA, and digitize X-ray film without digital images using a scanner.

Subsequently, the computer user 1 uploads the digital data obtained from the image to the web server 3.

The database server of the web server 3 plans the storage capacity according to the amount of images acquired. Since the amount of image data takes up a large part of the storage, a large database management system (hereinafter referred to as DBMS; Database Management System) is mainly used. It is divided into short-term and long-term storage. Image data of patients who are coming continuously for treatment or for research or other purposes should be stored short-term, but use the 3: 1 lossless compression method even if the amount of data is large. Because lossless compression methods of 10: 1 or more without using lossless compression methods can reduce the amount of data, but can adversely affect the precise reading of data loss, which is critical to patient care.

In addition, the unused images are stored for a long time after the treatment is terminated, and the data is reduced by a lossy compression method with a compression ratio of 10: 1 or more along with a read doctor's note. At this time, the storage method used is impossible to re-read the long-term stored image data because the image is lost due to compression and difficult to read accurately.

If the treatment is terminated and the image to be stored for a long time is used for future research or other purposes, use the lossless compression method.

In this manner, the digital image data stored in the web server 3 can retrieve and retrieve the image stored in the DBMS under the control of the system control program 30-1a. To see the image displayed on the screen, the conditions as shown in Table 1 must be met.

Table 1

That is, when the user 3 accesses the web server 2 through a computer communication network and searches for digital image data of a desired patient, the user 3 transmits the retrieved digital image data to the user computer 3. The user 3 downloads the transmitted digital image data, and outputs the image input in the digital format using a laser film printer, a 35mm slide maker, or the like.

As an operating system for providing a computer environment in a general computer is required, the present invention requires a network operating system (NOS) for providing a network environment. Network operating systems include Windows NT and Unix.

In order to deliver a large amount of data to a user quickly when viewing a video through a network, a high speed network is required, and ATM is used as a high speed network. ATM is a telephone-based technology that can deliver image, data and voice on a single line.

In addition, many applications can be used when constructing a network, and C / S methods that can efficiently use resources can be used. On the other hand, a host that facilitates network management by the network administrator by taking charge of all processing in the host. You can also use the terminal (host-terminal) method. Therefore, it is well known to those skilled in the art that the network construction method can be variously implemented and can be changed as many as possible without departing from the technical spirit of the present invention. .

2 is a block diagram of a medical care information service system through an Internet web site of the present invention.

The web server 30 of the present invention has a function of transmitting data desired by a user to a user browser through an internet protocol.

SQL (Structured Query Language) is used as the definition language for the database (DB) 30-2 constituting the web server 30, and the Active Server Page (ASP) is used as the system program 30-1. A program unit 30-1a and an encryption key generation program unit 30-1b are provided. The Active Server Page (ASP) program unit 30-1a manages a database 30-2 having information for enabling the transfer of medical information and medical images (such as X-ray film data) of patients. Control and enables data transfer to the user's browser over the Internet. In this case, it is possible to implement in a language such as PHP, Java Server Page (JSP) instead of the ASP program unit. In addition, the encryption key generation program unit 30-1b generates an encryption key based on the doctor's license number, social security number, and password of the user and the patient, and transmits the data to the user's browser and data on the Internet through the authentication of the user and the patient. Enable upload.

Meaning of the medical information used in the present invention refers to all medical information related to the patient, such as medical images, blood tests, the findings of the doctor in charge of X-rays, CT, MR, DSA, ultrasound, and other advanced imaging devices.

In addition, the structure of the database 30-2 using SQL as a data manipulation language for the task of enabling the transmission of medical information and medical image information (such as X-ray film data) of patients in the present invention will be described as follows. same.

The database unit 30-2 includes a user authentication DB 30-2a that enables the use of the medical treatment information service on the basis of the encryption key generated using the user's doctor's license number and password; A patient authentication DB 30-2b that enables the use of the medical care information service based on the encryption key generated using the patient's social security number and the password; Medical image data DB (30-2c) that holds digitally processed medical image information such as X-rays, CT, MR, DSA, and ultrasound of patients and medical information that enables medical information sharing by holding patient's medical information It consists of the information DB 30-2d.

3 is an operation flowchart when a medical image and a patient's treatment information are to be stored using a treatment information service system through an Internet web site of the present invention.

A user who wants to use the Internet web site that enables the medical service information service of the present invention should have a computer, a monitor, a modem, a telephone line, and a corresponding program for computer communication. An element is required.

When the user (doctor) who wants to transmit and upload the patient's medical information and medical image (X-ray film data, etc.) wants the Internet service of the present invention, the user 10 can access the user's computer through the Internet 20. After accessing the server 30 (S1) and joining membership, the medical care information service of the present invention is provided (S2).

After that, the computer user who is registered as a member goes through a step of inputting a doctor's encryption key (S3). If the computer user who has not been granted the doctor's encryption key is given an encryption key from the administrator, the doctor's encryption key is given by entering the doctor's license number and password (S4 to S5).

Thereafter, the computer user enters the encryption key of the doctor and then enters the encryption key of the patient to check the treatment information (S6).

By entering the patient's encryption key, the computer user can transmit the medical information of the patient and the medical images taken by the image diagnosis device, and the medical information and medical images of the patients anytime and anywhere without time and space constraints. Ray film data, etc.) may be uploaded to provide doctors of other hospitals with information enabling fast and accurate medical services (S9).

If the patient has not been given the encryption key from the administrator, the patient is given the encryption key from the administrator in the same manner as the doctor is granted the encryption key, but the patient's encryption key is entered by entering the patient's social security number and password. Is given (S7 ~ S8). The computer user who has received the patient's encryption key enters the patient's password key into the web server 30 to store the patient's medical record and the patient's medical image to be uploaded to the web server 30 to provide medical care nationwide. By integrating agencies into one, sharing information and facilitating exchange of information is facilitated.

4 is an operation flowchart when a medical image and a patient's treatment information are to be inquired using the treatment information service system through the Internet web site of the present invention.

First, it is determined whether a computer communication user (doctor) accesses an Internet web site for medical information service of the present invention. A user usually uses computer communication (for example, Cheon Lian, Heitel, Naunuri or Must be affiliated with Unitel or the Internet. Therefore, in order to access the web site (or home page) of the Internet, the user must access the Internet through domestic computer communication or directly access the Internet and connect to the corresponding Internet address.

All of these things can be recognized and controlled through the monitor screen, not only through a computer, but also through a modem (or ISDN or dedicated line) that sends and receives data.

When the user's computer terminal 10 is connected to the web server 30 for medical information service on the Internet through the computer communication 20, the user can see the initial main menu screen displayed through the screen of the monitor. There is (S11-S12).

When accessing the web site of the present invention using Internet Explorer or Netscape, the login process is performed from the main screen. If you are already a member, you will be logged in and go through the confirmation process. If a member is not registered, the member enters into a member-only corner after saving after registering.

After that, the computer user who is registered as a member goes through a step of inputting a doctor's encryption key (S13). If the computer user who has not been granted the doctor's encryption key is given an encryption key from the administrator, the doctor's encryption key is given by entering the doctor's license number and password (S14 to S15).

Thereafter, the computer user enters the encryption key of the doctor, and then enters the encryption key of the patient whose medical information is to be checked (S16).

By entering the patient's encryption key, the computer user can receive the patient's medical information and medical images taken by the image diagnosis device, and can quickly and easily view the patient's records anytime and anywhere without time and space constraints. And accurate medical service can be performed (S19-S20).

If the patient has not been given the encryption key from the administrator, the patient is given the encryption key from the administrator in the same manner as the doctor is granted the encryption key, but the patient's encryption key is entered by entering the patient's social security number and password. Is given (S17 ~ S18). The computer user who checks the encryption key of the patient may inquire and receive the patient's medical record history by inputting the encryption key of the patient in the web server 30.

This allows the doctor to take pictures of the patient's X-rays as well as the ability to analyze medical images taken with advanced imaging devices such as CT, MR, DSA, and ultrasound, or when there is a need for help from another competent doctor. If a digital image is processed instead of one film and uploaded to the web server 30, a doctor who has received an analysis request can download the medical image of the patient from the web server 30 and read it. Ensure high medical care.

In addition, even if a patient is transferred to a large hospital from a small or mid-sized hospital located in a rural area, or if the patient needs to move and change the hospital inevitably, medical images can be transmitted between remote hospitals. It prevents unnecessary waste (time, manpower) caused by re-shooting the ray, and shares the patient's medical information between hospitals, thereby preventing the doctors from misdiagnosing so that patients can receive accurate medical care.

In addition, it converts medical imaging film taken with an image diagnosis device such as X-ray into digital data, converts it into a database, uploads it to a recording medium, and downloads it if necessary to watch it on a computer monitor. To avoid wasted space and human resources.

An embodiment of an encryption key generation method for authenticating a user and a patient will be described with reference to Table 2 below.

First, a method of generating an encryption key for a user generated using a pseudo license number and a password will be described.

If you enter a doctor's license number (8 digits: 2 digits representing the medical field + 6 digits of the license) and a password (6 digits) as the input value, the user's encryption key is generated by the following algorithm.

1. Input value

license: 12345678 (2-digit medical course, 6-digit license number)

userpassword: kiss98

2. Output value

User (physician) identity key

First, 1) encrypt the license number.

12345678

12 345678 (separate two front seats and six rear seats)

12 678345 (Change back and forth by cutting off 6 backseats 3 times)

12 684 735 (Rearrange even six backseats)

12684735 (Rejoin)

-> 1x6r4s3u (replace the second, fourth, sixth, and eighth numbers with the corresponding array value)

Random array [10] = {z, y, x, w, v, u, t, s, r, q}

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

That is, the second number 2 is replaced by x, the fourth number 8 is replaced by r, the sixth number 7 is replaced by s, and the eighth number 5 is replaced by u. The random array value is changed by the system administrator from time to time so that others cannot easily obtain the authentication key.

2) The user's password is then encrypted.

Find the number for the odd and even letters in Table 2 and find each.

k i s s 9 8

-> k s 9-> 81 50 16 (odd)

-> i s 8-> 41 50 30 (even number)

-> Add two numbers obtained by referring to Table 2 (815016 + 415030)

-> 1230046

3) Combine the value obtained in 1) with the value obtained in 2).

-> Divide the value obtained by 1x6r 4s3u (1) into 4 digits after the first 4 digits.)

-> 4s3u 1x6r (swap two positions)

-> Insert the value obtained from 4s3u 1230046 1x6r (2) between them.)

=> 4s3u12300461x6r (last key value is generated)

Therefore, the encryption key required in the first authentication process for the user to receive the medical care information service of the present invention is the encryption key from the web server by the user inputting a doctor's license number (1234ense) and password (userpassword: kiss98). (4s3u12300461x6r) is given.

Thereafter, referring to Table 2, a description will be given of a method for generating a patient's encryption key required for the user to upload or download the patient's medical information and medical image data.

In the case of the patient, the encryption key is given through the web server through the same process as that of the user.

First, if the patient's social security number and password (6 digits) is input as the input value, the user's encryption key is generated by the following algorithm.

1. Input value

jumin1 (number before the resident number): 720425

jumin2 (last digit): 1234567

userpassword: kiss98

2. Output value

Patient identity key

First, 1) encrypt the social security number (jumin2).

1234567

1 234567 (separate one front and six rear seats)

1 567234 (Twist the last 6 seats 3 times to switch back and forth)

1 573624 (Rearrange even six backseats)

1573624 (rejoin)

b57d62e (replace the first, fourth, and seventh numbers with the corresponding array

Random array [10] = {a, b, c, d, e, f, g, h, i, j}

0, 1, 2, 3, 4, 5, 6, 7, 8, 9

That is, the first number 1 is replaced by b, the fourth number 3 is replaced by d, and the seventh number 4 by e. The random array value is changed from time to time by the system administrator as above so that others cannot easily obtain the authentication key.

Then, 2) encrypt the patient's password.

Find the number for the odd and even letters in Table 2 and find each.

k i s s 9 8

-> k s 9-> 81 50 16 (odd)

-> i s 8-> 41 50 30 (even number)

-> Add two numbers obtained by referring to Table 2 (815016 + 415030)

-> 1230046

3) Add the password encrypted using the first digit of the social security number and 2).

720425 (the first digit of the resident number) + 1230046 (2) plus the value obtained)

-> 1950471 (calculate what you have done so far)

4) Multiply the number obtained in 3) by the arbitrary number 13.

-> 1950471 * 13 (multiply any number (13))

-> 25356123

5) Add the last digit of your social security number to the number obtained in 4).

25356123 + 1234567 (after the resident registration number)

-> 26590690

6) Combine the value obtained in 1) with the value obtained in 5).

-> Divide the value obtained in b57 d62e (1) by 3 digits before and 4 digits after)

-> Enter the value obtained by b57 26590690 d62e (5) in between)

=> b5726590690d62e (last key value is generated)

Therefore, the user is required to enter the patient's social security number (jumin1: 720425, jumin2: 1234567) and password (userpassword: kiss98) in the web server for the encryption key required in the second authentication process in order to receive the patient's medical information service according to the present invention. The patient's encryption key (b5726590690d62e) from the web server.
