Description
Technical field
The present invention relates to field of information security technology, it is more particularly related to a kind of wisdom based on block chain
Urban information uses method and system safely.
Background technique
With the continuous development of human society, future city will carry more and more populations.Currently, China is in city
In the period of town accelerated development, some areas "urban disease" problem is increasingly serious, to solve urban development problem, realizes that city can
Sustainable development, construction smart city have become world today's urban development an irreversible historical trend.
The patent of invention of patent application publication CN108830601A discloses a kind of smart city letter based on block chain
Breath safe handling method and system include the following steps: that receiving user executes intelligent contract request；It is looked into according to the request of intelligent contract
Data directory on block chain is looked for, requested date address is obtained；Encrypted data are obtained from requested date address, and are solved
It is close, it after decryption, is encrypted using the key of corresponding sandbox, is then forwarded to corresponding sandbox；It is carried out using the data after decryption
The operation result of operation result and other block chain node sandboxs is carried out common recognition calculating by intelligent contract operation；Common recognition calculates logical
Later, result is sent to the user for issuing and executing intelligent contract request.A kind of wisdom based on block chain described in the invention
Urban information safe handling method realizes in smart city between multiple solid tissues effective information sharing processing and sensitive believes
Cease secret protection.
But it is in actual use, still there is more disadvantage, if the invention is in use to data classification pipe
Manage indefinite, user information and interaction data management intensity are low.
Invention new content
In order to overcome the drawbacks described above of the prior art, the embodiment of the present invention provides a kind of smart city information based on block chain
It uses method and system safely, awards reason mould by setting information interactive module, sensitive data module, authentication module, permission
Block and identity data recording module, first detect the face image of user, voice and password, pass through face recognition list
Member, voice recognition unit and password identification unit carry out typing to the body data of interaction personnel, at the same to the qualification of personnel and
Background case carries out archival of information, to the government of personal user information, general data data, privacy of user data, national security
The data of organization data and enterprise's secrecy, are stored, while will be stored in Profile data and prevent by information according to classification
Data storage inside modules are arrived in storage after protecting the encryption protection processing of module, carry out verifying to the permission of user and award reason, according to
The permission of user's application, can interact the other data of correlation level, pass through business secure data cell, privacy of user number
The data to maintain secrecy according to unit and government organs' data cell to privacy of user data, government organs' data of national security and enterprise
It is managed concentratedly, while needing the typing of identity data to the user of this interactive data, submitted after qualification after testing related
Department is examined, is carried out data interaction after verifying when interacting data to identity, is needed in use, awarding reason mould by permission
It is sent after the authentication of the permission grant and authentication module of block to central processing unit and releases the instruction of information locking permission, it
Data needed for central processing unit is sent to user, unit or the mechanism for releasing permission afterwards have to interact to data
Effect carries out clearly Classification Management to data, promotes user information and interaction data management intensity, reinforces in use process
Personal information safety carries out data interaction according to corresponding permission, the standardized management to data interaction, to solve above-mentioned background
The problem of being proposed in technology.

According to unit (16).
6. a kind of smart city information security application method based on block chain, it is characterised in that: specific step is as follows:
Step 1: detecting first to the face image of user, voice and password, pass through face recognition unit (11), voice
Recognition unit (12) and password identification unit (13) carry out typing to the body data of interaction personnel, at the same to the qualification of personnel and
Background case carries out archival of information, to the government of personal user information, general data data, privacy of user data, national security
The data of organization data and enterprise's secrecy, are stored, while will be stored in Profile data and prevent by information according to classification
Storage is internal to data storage module (8) after protecting the encryption protection processing of module (9), carries out verifying to the permission of user and awards
Reason can interact the other data of correlation level according to the permission that user applies；
Step 2: the storing data in step 1 is encrypted and is protected later, when the data information of encryption and protection is let out
When dew, related personnel is promptly prompted, the protection dynamics of message protection module (9) is reinforced later；
Step 3: passing through business secure data cell (14), privacy of user data cell (15) and government organs' data cell
(16) data of privacy of user data, government organs' data of national security and enterprise secrecy are managed concentratedly, while right
The user of this data of interaction needs the typing of identity data, submits relevant departments to be examined after qualification after testing, interaction money
Data interaction is carried out after verifying when material to identity；
Step 4: carrying out grade and delineation of power to interactive data, general data enters data storage module (8) after dividing
Inside is stored, and permission data needs to store after the encryption and protective treatment of message protection module (9)；
Step 5: needing in use, the identity for the permission grant and authentication module (5) for awarding reason module (6) by permission is tested
It is sent after card to central processing unit (1) and releases the instruction of information locking permission, later use of the central processing unit (1) to releasing permission
Data needed for person, unit or mechanism are sent, to be interacted to data.
7. a kind of smart city information security application method based on block chain according to claim 6, it is characterised in that:
The body data of interaction personnel is that data are arranged in face data, units of speech data and password in the step 1.
