As shown in the figure, the electronic prescription operation method includes steps (S509 and S511) of generating an encryption key (information) using the authentication information in the encryption management apparatus 200, (S501 to S507, S515 to S519) of encrypting the electronic prescription and storing the encrypted electronic prescription in the encryption management apparatus 200 and storing the encrypted electronic prescription in the relay apparatus 300 as a separate space (Steps S523 to S531, S533 to S539) in which the pharmacy apparatus 400 reads the encryption key and the encrypted electronic prescription corresponding to the authentication information from separate spaces, respectively, at the time of preparation And decrypting the encrypted electronic prescription using the encryption key (S541 to S545).

Hereinafter, a method of operating an electronic prescription by the electronic prescription system according to an embodiment of the present invention will be described in detail with reference to FIG. 1 to FIG.

First, when a patient visits a hospital and receives medical treatment, the doctor performs a medical treatment on the patient, and if necessary, prepares a prescription corresponding to the patient's disease.

That is, when receiving the prescription document 10 created by the doctor (S501), the hospital apparatus 100 generates an electronic document corresponding to the prescription document 10 (S503), and transmits an electronic signature for authentication of the electronic document (S505), and then requests the encryption management apparatus 200 for encryption information. At this time, the hospital apparatus 100 transmits a key request message including the authentication information to the encryption management apparatus 200 (S507). The authentication information can use the patient's medical care information, and for example, the medical care institution number and the patient's resident registration number of the hospital can be used from the medical care information.

In response to the request of the hospital apparatus 100, the encryption management apparatus 200 generates an encryption key using the authentication information included in the key request message (S509), transmits a key issuing message including the generated encryption key to the hospital apparatus 100) and issues encryption information (S511). Here, the encryption management apparatus 200 generates a symmetric key for encryption using the authentication information provided from the hospital apparatus 100, provides the symmetric key to the hospital apparatus 100, and includes the authentication information as meta information The encryption key issuing information is stored and stored (S513). For example, the symmetric key may comprise a series of integer strings having a certain length or a mixed string of alphanumeric characters.

Then, the hospital apparatus 100 encrypts the electronic prescription using the encryption key issued from the encryption management apparatus 200 (S515), and generates the encrypted electronic prescription 20 (S517). Here, the hospital apparatus 100 can use the authentication information as meta information of the encrypted electronic prescription 20.

Next, the hospital apparatus 100 transmits the encrypted electronic prescription 20 to the relay apparatus 300 on the communication network (S519), and the relay apparatus 300 stores the encrypted electronic prescription received from the hospital apparatus 100 in the database (S521).

In this way, when the encryption key is stored in the encryption management apparatus 200, and the encrypted electronic prescription is stored in the relay apparatus 300, the patient can visit the pharmacy to request the medicine preparation, For example, his / her care information, which is the authentication information used at issuance of the encryption key, can be provided (S523).

The pharmacy device 400 accesses the relay device 300 through the communication network to request an encrypted electronic prescription when authentication information (medical information) is received (input). At this time, the pharmacy apparatus 400 may transmit the prescription inquiry message including the authentication information to the relay apparatus 300 (S525).

When the prescription inquiry message is received from the pharmacy device 400, the relay device 300 searches the database (S527) and reads the encrypted electronic prescription corresponding to the authentication information included in the prescription inquiry message (S529) The prescription delivery message containing the electronic prescription is returned to the pharmacy device 400 (S531).

In addition, the pharmacy apparatus 400 accesses the encryption management apparatus 200 through a communication network and requests an encryption key (information). At this time, the pharmacy apparatus 400 may transmit a key inquiry message including the authentication information to the encryption management apparatus 200 (S533).

When the key inquiry message is received from the pharmacy device 400 (S535), the encryption management apparatus 200 reads the encryption key corresponding to the authentication information included in the key inquiry message (S537) To the pharmacy device 400 (S539).

Here, the process of acquiring the encrypted electronic prescription and the process of acquiring the encryption key by the pharmacy device 400 may be performed at the same time or may be performed in reverse order.

The pharmacy station 400 extracts the encryption key included in the key delivery message received from the encryption management apparatus 200 and restores the encrypted electronic prescription provided from the relay apparatus 300 using the encryption key. In other words, the digital signature is decrypted using the encryption key (S541), the electronic document is decrypted using the encryption key (S543), and then the decrypted electronic prescription is displayed so that the pharmacist can recognize it.

Then, the pharmacist prepares the medicine according to the prescription information included in the electronic prescription and provides the medicine to the patient (S545).

As described so far, according to the embodiment of the present invention, a medical institution such as a hospital encrypts an electronic prescription generated at the time of a patient's examination by using an encryption key, stores the encryption key and the encrypted electronic prescription in separate spaces, , And the pharmacy can restore the encrypted electronic prescription using the symmetric key so that the convenience of the drug formulation can be increased by allowing the patient to make a prescription even if the patient does not have a prescription for the printed paper , It is possible to enhance the security of personal information such as a prescription of a patient by using an encryption key in the generation and decryption of an electronic prescription and to distribute the encryption key and the encrypted electronic prescription through a separate flow, It is possible to prevent leakage of information, thereby maximizing security.
