Data asset safety management, sharing management and value management are three important links in a data asset management system.
At the present stage, there are two main ways for data asset security management, sharing management and value management.
The first mode is to carry out classified encryption processing according to asset sensitive information and real-time monitoring and auditing of sensitive assets according to manual experience. After data distribution and transmission, information such as the number of times of calling and calling results of evaluation data assets is manually inquired for evaluation and analysis, unused assets in a certain period are manually evaluated and offline processed.
The second mode is to adopt artificial intelligence, and the system of revealing is prevented to intelligence based on data security and sharing formation, mainly includes: s1, classifying and identifying the sensitive information; s2, sensitive data transmission processing and management and control; and S3, intelligent data monitoring and auditing.
However, the existing data asset management mode has certain risks, such as auditing and monitoring of sensitive information according to manual experience, and omission risks of sensitive information, sensitive actions and the like. If the data asset sensitive information and the data processing management and control are identified through artificial intelligence, but the non-sensitive information is not managed and controlled, the data asset sensitive information and the data processing management and control are easily tampered in the transmission process, so that the risk of data failure is caused.
In order to solve the prior art problems, embodiments of the present application provide a method, an apparatus, a device, and a computer storage medium for data asset management.
In the embodiment of the application, data assets are obtained from a data warehouse, the data assets are stored and linked up to obtain block data, the block data are distributed to a server, the data distribution condition and the use process of a user are recorded in the form of a block chain, return data sent by the server are received, the return data are operation data of the user using the data assets according to the block data received by the server, data value evaluation, data analysis and visual display are automatically performed according to the operation data, the data assets which are not used for a long time and do not generate data values are automatically processed, manual evaluation and analysis are not needed, the labor cost is reduced, and the data asset management efficiency is improved.
The following first describes a method for managing data assets provided by the embodiments of the present application.
FIG. 1 illustrates a flow diagram of a method for data asset management provided by an embodiment of the present application. As shown in fig. 1, the method may include the steps of:
and S110, acquiring the data assets from the data warehouse.
The data assets are digital assets of common individuals and enterprises, for example, various data which are obtained by taking photos, videos, edited documents and the like at ordinary times and take files as carriers belong to the data assets of individuals. For an enterprise or organization, design drawings, contract orders, and any business that involves the use of documents as carriers belong to the data assets of the enterprise or organization. Particularly for enterprises or organizations, data assets provide reasonable basis for management control and scientific decision-making of the enterprises or organizations.
Enterprises or organizations can acquire data assets from internal data warehouses through data asset management devices, and can also acquire data assets from external data warehouses through cooperation, lease and other means.
S120, the data assets are stored and linked up to obtain block data.
And the data asset management device stores and chains the data assets acquired from the data warehouse by adopting a block chain technology, and packs the data assets into blocks according to a chain data structure to be stored, so as to obtain block data.
In some embodiments, after the data asset is obtained, the data asset is encrypted with a digital signature prior to being stored on the chain.
Digital signatures are a method for authenticating digital information using encryption techniques that use public keys. In the block chain technology, the digital signature relates to tools such as a public key and a private key, and has two functions: firstly, the message is proved to be actually signed and sent out by a message sender, and secondly, the integrity of the message is determined and the message is not tampered. Sensitive information is not tampered in the transmission of the digital signature, and people without authentication and authorization can not see original data, so that the security of sensitive data in the transmission of the digital signature is realized.
Taking data a as an example, as shown in fig. 2, the digital signature encryption method includes the following steps:
s210, calculating the hash value of the data A to be transmitted through a hash algorithm.
And S220, generating a digital summary H according to the hash value of the data A to be transmitted.
And S230, encrypting the digital abstract H through a private key to generate a digital signature C.
And S240, sending the data A to be transmitted and the digital signature C to the server.
It should be noted that the user information is private data, such as the name, age, and phone number of the user, and this part of information is encrypted and shielded for data verification in the data asset, but is not transmitted as sharable data. The user data is stored, associated and transmitted by the user unique code.
The data assets comprise sensitive asset information and non-sensitive asset information, the sensitive asset information and the non-sensitive asset information which are subjected to digital signature encryption are integrally subjected to data encapsulation to form a chain-type data object, and the uniqueness of the data assets is ensured through a unique coding mechanism so that the data assets cannot be copied and tampered, thereby ensuring the safety of the data assets.
S130, distributing the block data to the server.
The data asset management device controls the authority to determine the transmission object. The data asset management device may specify a block chain of write permissions in only one organizer's hand, and read permissions may be open to the outside or read permissions of arbitrary programs may be restricted.
And according to system scheduling, appointing a data asset requirement period according to an opposite end, distributing the block data to an opposite-end usable service end, and distributing the block data to a plurality of service ends at the same time.
The distribution process records information and uses another set of encryption rules, so that users cannot decrypt the information, such as events, state data and the like generated by operation. The part is a private chain, only the block chain technology is adopted for recording, the recording is not public, and only the internal circulation is recorded and is shared by an asset manager.
And recording events, states and time generated by the integral operation of the data is the right to confirm so as to ensure that the integral flow of the data is traceable and safe to use and is valuable.
S140, receiving the returned data sent by the server, where the returned data is the operation data of the user using the data asset according to the block data received by the server.
After distributing the block data to the server, the server first decrypts the block data. And when the server receives the data a to be transmitted and the digital signature C sent to the server in the step S240, decrypting the data a and the digital signature C. As shown in fig. 3, the digital signature decryption method includes the following steps:
s310, calculating a hash value of the received data a through a hash algorithm.
S320, a digital digest H1 is generated according to the hash value of the received data a.
S330, the digital signature C is decrypted through the public key to obtain a digital digest H2.
And S340, when the contents of the digital summary H1 and the digital summary H2 are consistent, verifying that the received data A is correct information.
After verifying that the received data A is correct information, the user can use the data assets at the server side. The user can use the data in the public chain block, but the events, state data and the like generated by the data asset operation in the private chain are encrypted independently and cannot be decrypted for use.
When the user uses the data assets at the server side, the sensitive action triggers a security auditing mechanism. The safety auditing mechanism is controlled according to the safety authority, the use of the block chain by the user is limited to the reading use by authorized participants, the data calling, the association analysis, the modeling training, the flexible and comprehensive inquiry and analysis of the data and the like can be carried out, but the data cannot be copied, modified and detailed information inquiry operation cannot be carried out due to the appointed authorization limitation, so that the safety of the data assets is ensured. And starting the whole process from decryption to data use from the server, recording the whole operation action, the operation times, the operation time stamp and the like of the user on the block, recording action trigger information, and returning the private chain block recording the whole action to the data asset management device.
In addition, the block data can be transmitted to the next-level server, and the server compresses all information recorded in the previous block, records all user operation data, encrypts and transmits the operation data to the data asset management device. The block structure of the block data is very important, the block header of each block contains the compressed value of all transaction information of the previous block, so that a chain is formed from the starting block to the current block, and the complete block chain records all operation records in the data transmission process. Wherein, each block contains a plurality of attribute information, for example, block size information, which records the size of the current block; the block header information records the header information of the current block, and the hash value of the block header information is a parameter of the next new block; transaction counting information, which records the flow number recorded by the current block; a timestamp recording the time of current block generation, in accordance with the UNIX time format of UNIX; and transmitting information, wherein all transmission details stored in the current block are recorded.
The data asset management device receives the returned data, namely the operation data, sent by the server side, so that the use condition of the data asset can be conveniently evaluated and analyzed, corresponding processing measures are taken, manual evaluation and analysis are not needed, the process of obtaining the operation data and the evaluation and analysis data is simplified, the labor cost is reduced, and the management efficiency of the data asset is improved.
And S150, processing the data assets according to the operation data.
And the data asset management device decrypts the operation data returned by the server, evaluates and analyzes the data asset according to the decrypted operation data, and takes corresponding processing measures.
In some embodiments, the operation data includes operation actions, operation times, operation time, wherein the operation actions include operation actions of merging, splitting, copying, deleting and the like. Through the operation actions, the operation time and the operation times, the data asset use condition of the user can be obtained, the data asset use condition of the user is analyzed, the data asset life cycle is evaluated, and the operation analysis data is obtained. The operation analysis data comprises evaluation data of data asset redundancy conditions, assets which are not used for a long time and do not generate data value are intelligently analyzed, automatic distribution stopping processing, automatic offline processing and the like are achieved, asset redundancy is avoided, resource input cost is reduced, and the life cycle of the data is managed.
Aiming at the sensitive action of the user, the data asset management device triggers a sensitive operation safety auditing mechanism to audit the sensitive information, and the non-safe action is forbidden to be used.
In the embodiment of the application, data assets are obtained from a data warehouse, the data assets are stored and linked up to obtain block data, the block data are distributed to a server, the data distribution condition and the use process of a user are recorded in the form of a block chain, return data sent by the server are received, the return data are operation data of the user using the data assets according to the block data received by the server, data value evaluation, data analysis and visual display are automatically performed according to the operation data, the data assets which are not used for a long time and do not generate data values are automatically processed, manual evaluation and analysis are not needed, the process of obtaining, evaluating and analyzing the operation data is simplified, the labor cost is reduced, and the data asset management efficiency is improved.
