A specific example is given below.

Referring to fig. 4, in the data management system provided by the embodiment of the present application, various data related to urban management generated by a device layer (e.g., a data collection device such as an internet of things device) is uploaded to a central server, that is, a central server (central layer) of urban data, where the central server collects information such as video, audio, images and the like from different scenes of a city, and after various algorithms (e.g., an Artificial Intelligence (AI) algorithm) process the information, such as monitoring behaviors such as violations and law violations, events of different topics such as intrusion detection, careless swimmers, public facility damage, private establishment, fire alarm and the like are automatically released, and functional departments such as a traffic bureau, a city administration, an emergency management bureau and the like subscribe to the event list in advance in a targeted manner through respective user terminals (i.e., user layers) for respective service ranges, so as to make timely processing when subscribed event notifications are received. The whole data flow process can carry out real-time evidence storage through a blockchain platform (namely a public layer), the data flow process can be traced when necessary, and the tracing request carries out authority matching through an intelligent contract, so that the data safety is ensured.

Therefore, the data management system provided by the embodiment of the application effectively improves the work efficiency of the government functional departments, monitors the response speed of the government functional departments, solves the possible divergence among the government functional departments, and improves the overall image of the government.

Then, referring specifically to fig. 4, the data management system provided in the embodiment of the present application mainly includes the following four parts: the device layer, the middle platform layer, the user layer and the public layer have the following specific functions and data processing modes:

device layer: the equipment layer mainly comprises Internet of things equipment and is mainly responsible for sending video, audio, images and other data from different scenes of the city to the middle platform layer in real time. The uplink certification storing request sent by the process mainly stores the position of the equipment, the real-time state of the equipment and the like. Referring to fig. 5, the apparatus includes, for example: camera, smoke alarm, security alarm, GPS locator, etc.

Middle layer: i.e. the city data staging. Referring to fig. 6, according to the functional division, for example, an event publishing module, a member management module, an AI algorithm module, a data processing module, a storage module, etc. (of course, there may be other division modules, which are not limited in the embodiment of the present application). Wherein:

And a member management module: responsible for approval joining of user layer members: when a user layer member (different government functional departments) applies to add to a data center (or can also be called an addition system), the module performs auditing, configures roles and authorities of the module and adds the module to a blockchain platform; how to audit can be determined according to actual needs, and the embodiment of the application is not limited.

In addition, the member management module is also responsible for approving the user layer event subscription list: after the user layer member subscribes to the event of interest (such as intrusion detection, channel occupation, smoke and fire identification, unattended operation, illegal parking, etc.) in the event list, a subscription request is initiated to the middle layer, and a member management module of the middle layer is responsible for auditing and approval. How to audit can be determined according to actual needs, and the embodiment of the application is not limited.

In some embodiments, the system described in embodiments of the present application involves two event subscription lists, such as: the subscription event list a of the data center is a complete set, assuming a total of a, b, c, d events, while the user-layer event subscription list is a subset of a, possibly only two events a, c.

And a data processing module: is responsible for processing data from the device layer, such as decoding, cropping, video shot segmentation, key frame extraction, feature extraction, etc.

AI algorithm module: and the method is responsible for calling corresponding algorithms, such as a video processing algorithm, an audio processing algorithm, an image processing algorithm and the like, aiming at different types of data from the equipment layer, and intelligently identifying the data of video, audio, images and the like. When information such as illegal and regulation violations is detected, namely, the existence of events needing to be released is determined, the event releasing module is used for releasing the events of different topics, such as intrusion detection, lane occupation operation, smoke and fire identification, unattended operation, illegal parking and the like.

Event issuing module: is responsible for publishing events of different topics. Specifically, according to the subject of the event to be published and subscription information of the user terminal from the user layer, a corresponding event notification is published to the user terminal.

The event publishing module principle of the middle platform layer is shown in fig. 7.

The user layer department 1 (first user terminal), the user layer department 2 (second user terminal) and the user layer department 3 (third user terminal) respectively report to the city data center in advance according to the requirements and apply for subscribing to the events of different topics. After the urban data center publishes the events of different topics, different departments of the user layer respectively receive the event notifications of the corresponding topics according to the event subscription list.

For example, as shown in fig. 7, the user layer departments 1 and 2 subscribe to the first theme event in advance, and the user layer departments 2 and 3 subscribe to the second theme event in advance, then the city data middle station sends the notification of the first theme event to the user layer departments 1 and 2 and sends the notification of the second theme event to the user layer departments 2 and 3.

And a storage module: is responsible for storing the original data (including video, audio, images, etc.) from the device layer and the data processed by the data processing module.

In the embodiment of the application, after the data of the equipment layer is sent to the middle layer for processing, in the process of issuing different theme events after intelligent recognition, the data carried in the uplink certificate storage request mainly comprises: the method comprises the steps of issuing a theme, time, a data source side, a source position and source time of an event, and associating hash values of data processed by a data processing module, wherein the hash values of associated data can indicate which piece of video, audio, image and other data the event is calculated from.

In the embodiment of the application, the tracing request mainly traces the event circulation process, for example, the following tracing result is obtained:

The user layer several departments subscribe the event, process the mode, process the result, process time, receive the time of event notice;

the time of the middle layer initiating event notification;

information of data acquisition equipment related to events such as data source side, source position, source time and the like.

It should be noted that, as a city data middle station, a tracing request can be initiated for all event topics.

User layer: mainly including government functions, see fig. 8, for example: users with different identities such as emergency administration office, city administration office, traffic office and the like. Each office may be implemented with a specific user terminal, which is divided into functions, and may include a service processing module and a storage module, for example. The service processing module can present a user interface to a user for realizing the functions of event subscription, event notification reception, event notification processing, uplink evidence storage, source tracing and the like. The storage module is used for storing various data information and the like related in the processing process.

Specifically, in the user layer, the service processing module of each office first needs to subscribe an event subscription list (for example, the emergency management office subscribes only to the smoke alarm and flood alarm events, then the subscription list of the office is the smoke alarm and flood alarm), when receiving the event notification of the middle layer, the service processing module responds to the event, and processes the original data uploaded by the content-associated equipment layer such as the time, processing mode and processing result of the event notification through the data processing module of the middle layer (namely, the original data uploaded by the equipment layer is A, and the hash value of B is obtained after cutting through the data processing module of the middle layer), and then performs uplink storage. The respective storage modules mainly store the data (namely B) of the original data uploaded by the equipment layer associated with the subscription event after being processed by the middle layer data processing module. The source tracing request sent by the service processing module mainly traces the event circulation process, such as the processing mode, the processing result, the processing time, the time for receiving the event notification, the time for initiating the event notification, the data source side, the source position, the source time and the like, and it is to be noted that, as a user layer, the source tracing request can only be initiated for the event subject subscribed by the user, for example, the emergency management bureau only subscribes for the smoke fire alarm and flood alarm events, and then the subscription list of the bureau is two items of smoke fire alarm and flood alarm.

Public layer: the main functions of the block chain platform include verifying and tracing the data acquisition equipment state, equipment position, user subscription list, various event topics and details of the equipment layer, and performing authority management on the user layer.

The blockchain platform is generally a alliance chain, has an identity management function, is responsible for joining each member of a user layer, registering and logging in the member, and is configured with different attributes, and corresponds to different authorities and roles of the user according to the different attributes, such as ordering nodes, endorsement nodes, submitting nodes, anchor nodes and the like. The blockchain platform is a distributed system, each user (including a middle platform layer, namely a city data middle platform) corresponds to a node server, and all nodes form the whole blockchain platform. Wherein different node types are different in division of labor, namely different in responsibilities:

submitting node: receiving the generated block, verifying the transaction and billing;

endorsement node: the method is responsible for executing the transaction and signing and endorsing the result, and is only an endorsing node when the transaction endorsing is initiated, and is a common submitting node at other times;

anchor node: is responsible for representing information exchange between one part of nodes and another part of nodes;

Sorting nodes: and receiving the transaction containing the endorsement signature, and sequencing unpacked transactions to generate a block.

Referring to fig. 9, the smart contract module of the public layer includes an administrator contract module and an access control contract module, and the principle for implementing rights control is shown in fig. 10. Specifically:

an administrator contract module: the administrator contract module maps the identity (e.g., ID string) required by the user layer member to log into the system to its blockchain account address, enabling specification of newly joined users or changing the mapping of existing user identities. Wherein, the newly added user refers to mapping the ID and the blockchain account address of the newly added user, and writing the attribute value of the user into a blockchain platform (the blockchain platform has a database, in particular into the database); the changing of the mapping of the existing user identity refers to changing the mapping relationship between the user ID and the blockchain account address, such as mapping other IDs onto the blockchain account address.

Wherein, the attribute values of the user include, for example, the following attributes:

identity of the user: such as a city level metropolitan area, district level metropolitan area, city level traffic area, district level traffic area, etc.;

A set of user's subscription event topics;

a set of operational permissions for event topics to which a user subscribes: for example, the user has no authority on the subscribed event theme, or has authority such as read-only, write-only, readable and writable; different event topics subscribed by the user can have different operation authorities;

operable time of event topics to which the user subscribes: for example, [ ts, te ] means that in the time period from ts time to te time, the user has corresponding operation authority on the event subject subscribed by the user; for another example, [ ts, - ] means that the user has corresponding operation rights to the event topic to which he subscribes at any time from the ts moment; different event topics to which the user subscribes may have different operation rights.

The operation authority of the user on the subscribed event theme can be applied in the process of subscribing the user layer to the event theme of the middle platform layer or other independent processes, the middle platform layer performs auditing (particularly, how to audit the embodiment of the application is not limited), and after the auditing is passed, the operation authority of the user on the subscribed event theme is recorded in an administrator contract module.

In some embodiments, the administrator contract module is also responsible for obtaining the user attribute values.

In some embodiments, the partial attribute values obtained by the administrator contract module are used as input to the access control contract.

An access control contract module:

inputting a part of attribute values of a user acquired by an administrator contract module and an event theme which the user wants to operate, for example, a smoke alarm event theme which the user wants to operate, wherein the input event theme is smoke alarm; the operation is, for example, writing, reading, etc. of the event body stored in the public layer by the user layer. The uplink credentials may be referred to as write operations, and the trace-source requests may be referred to as read operations.

Checking whether the user has corresponding authority through an access control contract module, such as no authority, read-only, write-only, readable and writable, and the like;

if the user has no authority to the event theme, the access control contract module outputs prompt information to prompt the user that the user has no authority;

if the user has read-only permission on the event theme, the access control contract module outputs prompt information to prompt the user about the data of the smoke and fire alarm theme;

If the user has write-only authority on the event theme, the access control contract module outputs prompt information to prompt the user to upload data related to the smoke alarm event theme;

if the user has readable and writable rights to the event theme, the access control contract module outputs prompt information to prompt the user to upload the data of the smoke and fire alarm event theme to the blockchain platform, and also to acquire the data of the smoke and fire alarm event theme from the blockchain platform.

In summary, the architecture of the entire data management system is shown in fig. 11.
