For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.
Set forth a lot of detail in the following description so that fully understand the present invention, but the present invention can also adopt other to be different from alternate manner described here to implement, therefore the present invention is not by the restriction of following public specific embodiment.
Secondly, the present invention is described in detail in conjunction with schematic diagram, when describing the embodiment of the present invention in detail; for ease of explanation; the sectional view of indication device structure can be disobeyed general ratio and be made partial enlargement, and described schematic diagram is example, and it should not limit the scope of protection of the invention at this.In addition, the three-dimensional space of length, width and the degree of depth should be comprised in actual fabrication.
For outstanding feature of the present invention, in accompanying drawing, do not provide directly related part inevitable with inventive point of the present invention.
Current patient to seek medical advice in process case history, diagnostic materials and medical image information still can not digitizing efficiently, even if digitizing, existing flash memory device all can not protect security and the privacy of patient information.Based on this, inventor studies discovery, use the management and control of the user right such as radio-frequency (RF) identification or fingerprint recognition information, and in conjunction with AES hardware encipher mobile storage data, thus realize the data encryption feature of high reliability, can perform according to different user rights the read-write that data are carried out in security control without the need to connecting subscriber authentication server.
Embodiment one
Fig. 2 and Figure 3 shows that the embodiment of the present invention provide China doctor card structural representation.As shown in Figure 2, the China doctor card provided in the present embodiment, comprise the radio-frequency card 1 and mobile memory 2 that are separated from each other, described radio-frequency card 1 is rectangular card, form the main body of China doctor card, wherein there is storage tank 11, the shape of this storage tank 11 and the form fit of mobile memory 2, in the present embodiment, mobile memory is rectangle flash disk, and thickness is slightly less than the thickness of radio-frequency card.
As shown in Figure 3, this mobile memory 2 is movably connected in storage tank, realizes being rotatably connected with radio-frequency card, communication interface can be exposed to outside radio-frequency card 1, be convenient to be connected with external unit such as PC along pointer storer 2 in rotary moving.
Fig. 4 cures for the embodiment of the present invention provides magnificent the functional module pie graph blocked, as shown in the figure, radio-frequency card 1 has been embedded in RFID tag 12, in this RFID tag 12, there is identity characteristic private key, this identity characteristic private key comprises user right eigenwert, and user right eigenwert is for limiting the processing authority such as reading, amendment, deletion, copy of user to data.
Described mobile memory 2 is as data store, and it comprises identity characteristic read module 21, encrypting module 22, data memory module 23 and communication interface 24.
Wherein, described identity characteristic read module 21 is radio-frequency (RF) identification chip, this radio-frequency (RF) identification chip 21 is for the identity characteristic private key that obtains in radio-frequency card 1 and send to encrypting module 22, namely REID (RadioFrequencyIdentification is adopted, RFID) user right information is read, to carry out the data processing of different rights after decryption; Described encrypting module 22 is AES chip, it carries out AES computing according to described identity characteristic private key, by encryption key comparison to determine that corresponding authority is to the data access in data memory module, described identity characteristic private key is as the primary encryption key assignments in AES computing.
AES(AdvancedEncryptionStandard) be a kind of symmetric key encryption standard, comprise three block ciphers, AES-128, AES-192 and AES-256, Fig. 5 is the AES encryption schematic diagram of encrypting module in the present embodiment China doctor card, as shown in the figure, AES chip be embedded in block cipher plaintext (P1, P2, P3 ... Pn), export after AES encryption computing ciphertext (C1, C2, C3 ... Cn), decrypting process then needs input encryption key (i.e. identity characteristic private key) to produce original plaintext.
As can be seen here, the private key (encryption key) of AES computing is deposited in the RFID tag in radio-frequency card, PKI is deposited in the AES chip 22 of mobile memory 2, identity characteristic private key then needs to be read in radio-frequency card by RFID technique, and then just by encryption and decryption computing, the data in data memory module 23 are processed, radio-frequency card 1 and mobile memory 2 are physically separated different parts, achieve the encrypted form that PKI is separated with private key, avoid the unreliable defect of software cryptography, improve the security of data processing.
In addition, the present embodiment realizes the process of AES encryption computing by AES chip, and the operation efficiency of AES hardware encryption algorithm is higher, and reading and writing data speed and unencrypted data almost do not have difference, effectively can improve the efficiency of China doctor card digital independent.
In the present embodiment, described data memory module 23 is FLASH storage chip, and the packing forms of described mobile memory can be SD, MemoryStick, MicroSD, MiniSD or MMC, and described communication interface 24 can be USB interface.
In the present embodiment, AES encryption bit is not limited to 128,192 or 256, also can use the calculation methods such as EBC, CBC, PCBC, CFB, OFB.
In addition, in described data store, embeddability application program is also comprised, for the treatment of the data in described data memory module.
In the China doctor card that the present embodiment provides, described data memory module 23 may be used for store patient personal information, medical insurance accounts information, medical image data and/or patient medical record information.Patient or doctor (i.e. the user of different rights) have respective radio-frequency card and corresponding identity characteristic private key thereof; this private key determines user right; read the authority information in radio-frequency card by the identity characteristic read module 21 in mobile memory in curative activity; data are processed according to different rights after encrypting module contrast, so achieve the mode that user right certification combines with data security certification to protect the safety of medical information and the privacy of patient.
China's doctor's card in the present embodiment, for IC-card, can be realized the certification of user right, without the need to through the webserver, eliminate hardware cost by radio-frequency card and mobile memory, easy to use, is conducive to the payment cost saving doctor and patient.In addition, the built-in RAM capacity of common IC-card is minimum, about 512K, and the China doctor card mobile memory in the present embodiment can be jumbo Flash chip, is convenient to store jumbo medical data fast.
For SD, MemoryStick or MiniSD, China's doctor's jig in the present embodiment has permission control, the user only meeting authority could read and write corresponding data, it not the software cryptography mode by more easily decoding or stealing, but realize hardware encipher mode by AES chip, PKI and private key are deposited in different parts respectively, and therefore security significantly improves.
For traditional radio-frequency card, the control of authority of the China doctor card in the present embodiment, need not pass through the webserver, corresponding do not have service centre and authorization process system thereof yet; Meanwhile, China doctor jig has the data larger than conventional radio frequency card capacity to store and function of exchange.
Embodiment two
