Specifically, in this embodiment, the block chain-based cross-department property management method further includes: the validity of the node is verified through a common identification mechanism (data is analyzed in a public key mode, whether the data is legal or not is verified according to the abstract), the block chain service analyzes the received broadcast block data (a block data packet is obtained) through a data sending message bus (a data interaction transfer point), a new block chain is added in a transaction (closed loop verification of leading data of various logic databases falling into a database and returning the data if a rule is not closed), the database node block is updated, and the processing result is returned and converted into standard response data according to service logic. And the service end of the browser or the mobile equipment responds to the uplink result of the block and displays the service data corresponding to the uplink.
The service system has a mechanism for analyzing and verifying the block at regular time, if the result of the block analysis is different from the service data, the abnormal tampering condition is shown, then the abnormal tampering condition is pushed to the service system to initiate an alarm, and the original data is traced through a signature and a preset rule. Illegal data is typically a tampering of non-business operations, such as: the method comprises the steps of tampering a database, packet capturing and intercepting, submitting illegal block uplink, forcibly modifying a single node block and the like, wherein the illegal data cannot pass through a consensus mechanism in the transfer process, and a block chain system blocks the abnormal uplink block and simultaneously informs a feedback service system to play a role in warning prompt.
Taking property attribute information registration as an example, 10g of gold jewelry of a property is registered, after the property is illegally modified to 8g, when a block chain is subjected to validity verification, the logic matching abnormality with a previous signature request is sent out, the situation is fed back to a service system, the service system carries out abnormality warning, a previous signature is called through a preset rule of the service system, the previous signature is analyzed and corresponds to broadcasted data, 10g of information jewelry registered at the previous time is restored, and the safety of the data is ensured.
Taking the property warehousing storage as an example, the property is put into the two-layer storeroom electronic article region antimagnetic cabinet, the property is illegally modified to be not warehoused for storage, when the block chain is subjected to legality verification, the logic matching between the block chain and the last signature request is abnormal, the situation is fed back to the service system, the service system performs abnormity warning, the last signature is called through the preset rule of the service system and is analyzed and corresponding to the broadcasted data, the last registration information is restored, the two-layer storeroom electronic article region antimagnetic cabinet is stored, and the safety of the data is guaranteed.
Taking property ex-warehouse as an example, the property evidence fruit knife is ex-warehouse for property evidence identification, when the property evidence fruit knife is illegally modified to be scissors out-warehouse, when the block chain is subjected to legality verification, the logic matching abnormality is sent out with the last signature request, the situation is fed back to a service system, the service system gives an abnormality alarm, the last signature is called through a preset rule of the service system and is analyzed and corresponding to the broadcasted data, and the property evidence fruit knife is restored to be ex-warehouse for property evidence identification, so that the safety of the data is ensured.
Taking property processing as an example, processing 5 ten thousand yuan to return to a party, illegally modifying the processing to 3 ten thousand yuan to return to the party, when the block chain is subjected to validity verification, sending a wrong logic matching exception with a last signature request, feeding the exception back to a service system, performing exception warning by the service system, calling the last signature through a preset rule of the service system, analyzing and corresponding to broadcasted data, restoring 5 thousand yuan to process and return to the party, and ensuring the safety of the data.
Taking the case that the property is transferred from a case management department to a case transfer department as an example, a property book and periodical list is transferred to the case transfer department, the property book and periodical list is illegally modified into a notebook photo, when a block chain is subjected to legality verification, the logic matching with a previous signature request is abnormal, the situation is fed back to a service system, the service system performs abnormity warning, a previous signature is called through a preset rule of the service system and is analyzed and corresponding to broadcasted data, the restored book and periodical list is transferred to the case transfer department, and the safety of the data is guaranteed.
In this embodiment, when the block analysis result is different from the service operation data, a tampering alarm is initiated through the service system and the original data is traced back, so that mutual constraint between multi-level and multi-level users is realized, and thus cross-department standard management of property is realized.
Optionally, the block chain-based cross-department property management method further includes: and performing anti-leakage protection on the service operation data through digital watermarking.
Specifically, in this embodiment, a digital watermark adding operation is provided for service data of each department, an "identity card" is provided for the data, and when a data leakage event occurs, the cloud platform extracts watermark information in the leaked data to compare with watermark information recorded in a log, so as to locate a leaking person, thereby tracking the use of unauthorized data. The settings using the digital watermark are associated with the data user or the data usage record and are not easily identified and erased. When the data user uses the data, the digital watermark is added, and the data can be protected from leakage by using the tracing technology of the block chain. Once the data containing the digital watermark is discovered to be leaked, the unauthorized data use can be tracked by associating the watermark characteristic with a data user.
In the embodiment, the service operation data is protected against leakage through the digital watermark, which is beneficial to the realization of cross-department standard management of property.
Although the present disclosure has been described with reference to the above embodiments, the scope of the present disclosure is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present disclosure, and these changes and modifications are intended to be within the scope of the present disclosure.
