Shamir's Secret Sharing Scheme (SSSS) is a secret sharing algorithm created by Adi Shamir. It divides a security key created by creating a plurality of security keys, that is, a secret key, into a key storage server at the time of data encryption, it is possible to decrypt the data even if the cryptographic key is lost, because the data can be reconstructed again as a part of the key (key). Since the data can be decrypted through the key combination of the key, not one key, do.

The virtual file system 24 is provided with an ID directory for each patient and has a physical file name (PFN) mapped to the LFN and LFN for the patient's medical data corresponding to the ID in each ID directory, ) Is stored and managed. Here, the PFN includes address information (SURL) and globally unique identifier (GUID) of the location where the encrypted medical data file is actually stored in the file storage. For example, the GUID can be 'f81d4fae-7dec-11d0-a765-00a0c91e6bf6', and the PFN can be represented as 'ftp://example_storage.net/medical_data/f81d4fae-7dec-11d0-a765-00a0c91e6bf6' , LFN can be expressed as '/medical_data/patent_1/MRI_20150601.tar.gz'.

The virtual file system is a system that enables management such as storing, copying, modifying, and deleting files stored in file storage, and is composed of a DBMS (Database Management System) such as MySQL, And the PFN so that encrypted medical data files can be downloaded from file storage or downloaded and stored.

The file storage 28 stores the medical data files encrypted by the encryption server, and each encrypted medical data file is stored in a physical file name (PFN) generated by the encryption server And stored and managed in corresponding locations. The physical file name (PFN) includes address information (SURL) for the actual storage location of the file storage and a unique file identifier for the file.

The management and operation server 29 performs authentication according to a predetermined policy for a user connected to the encryption server or manages policies related to authentication.

The encryption server 22 has a trigger process that is automatically executed when a preset event occurs and the processor receives the medical data file and patient information from an external medical data management server It runs automatically when an event occurs. There may be a variety of external medical data management servers that provide medical data files and patient information, and in particular, a DICOM server may be one. When the DICOM server stores the medical data files and the conversion to the compressed file is completed, the agent program installed on the DICOM server transmits the compressed medical data file and the patient information to the encryption server.

FIG. 2 is a flowchart sequentially illustrating the operation of a trigger process executed in an encryption server of the medical data encryption system according to the present invention.

Referring to FIG. 2, when the trigger process of the encryption server 22 receives the medical data file and patient information therefrom (step 100), it generates unique identification information (ID) for the patient, Patient information is stored to correspond to the generated ID (step 110). Next, the medical data is encrypted using a predetermined encryption algorithm and a plurality of cryptographic keys are generated (step 120).

Next, the ID and the plurality of cipher keys are divided and stored so as to correspond to the IDs in the plurality of key storage servers (step 130).

Next, the encryption server 22 stores the encrypted medical data file in the file storage and allocates the PFN according to the stored location (step 140).

Next, the encryption server 22 generates an ID directory using the ID in the virtual file system, generates a file name corresponding to the LFN, stores the LFN under the ID directory of the virtual file system, adds the PFN (Step 150). Here, the LFN includes a virtual file name and a location, and the PFN indicates a storage location of an actual file including an address (SURL) and a unique file identifier for the storage location of the file storage.

Next, the LFN is stored in a position corresponding to the ID in the patient metadata server (step 160).

Through this process, the encryption server encrypts and stores the medical data file in the file storage, manages the location information of the encrypted medical data file stored in the virtual file system, and stores the medical data file in a plurality of key storage servers Stores and manages a plurality of cipher keys that can be decrypted, and stores and manages metadata of patient information and medical data information for providing a search service to the patient metadata server.

<Medical data retrieval system>

Hereinafter, the medical data retrieval system of the medical data management system of the present invention will be described in detail. The medical data retrieval system according to the present invention is implemented by retrieval software installed and operated in a user PC, a portable terminal, etc., and the retrieval software retrieves a medical data file encrypted by the medical data encryption system, decrypts the retrieved file To the user.

FIG. 3 conceptually illustrates the operation of the medical data retrieval system according to the present invention. FIG. 4 illustrates a method of retrieving and providing decoded medical data by the retrieval software of the medical data retrieval system according to the present invention. And Fig.

Referring to FIG. 4, authentication is performed for a connected user through a predetermined method. When the authentication is completed (step 200), retrieval of medical data is enabled. If the authentication is not authenticated, the procedure is terminated. It is apparent to those skilled in the art that the technologies related to the authentication method for the connected user are already well known and can be implemented by selecting one of various well-known technologies. On the other hand, in the present specification, a user accessing the medical data retrieval system may be the physician of the hospital where the present system is installed or the responsible person of the related institution, and may be the patient himself depending on the situation.

When a search keyword related to a patient or the like to be searched is input from a user whose authentication has been completed (step 210), the terminal accesses the patient metadata server using the input search keyword, Obtain an LFN for the file (step 220).

Next, a PFN mapped to the retrieved LFN is obtained in the virtual file system using the retrieved LFN (step 230).

Next, a plurality of cryptographic keys corresponding to the ID are obtained from the key storage server using the searched ID (step 240).

Next, an encrypted medical data file stored in the file storage is obtained using the PFN (step 250), and the encrypted medical data file is decrypted using the obtained encryption keys (step 260).

Next, the decrypted medical data file is displayed on the screen, and the decrypted medical data file is provided in an output form according to the request of the user. If the user requests output to the printer, the medical data file decrypted by the printer connected to the retrieval system is output. If the user requests the download of the file, the decrypted medical data file can be downloaded to the predetermined data storage location will be.
