Detailed Description
The invention is described in further detail below with reference to the attached drawing figures:
the invention provides a method which comprises the following steps:
s1, forming a alliance chain by property preservation participant nodes, wherein the property preservation participant nodes comprise court nodes and ownership registration nodes, and the court nodes comprise various courts, such as a court A and a court B; the ownership registration node comprises a real estate registration center, a market supervision and management bureau, a vehicle management station, a security settlement center and the like;
s2, determining the abstract information of the legal document and the legal document of the property preservation by the court node, encrypting the legal document of the property preservation by using the public key of the corresponding authority, and linking the encrypted legal document and the abstract information to the supervision platform; when the encrypted legal documents and the summary information are uplink, the information uplink by the secondary court node is endowed with an uplink time stamp which is not changeable; the abstract information of the legal document comprises an executive case number of property preservation, identity information of an executed person, a property location and property attributes, and other information related to the current property preservation can be added in practice;
s3, the supervision platform records the uplink time stamp of the encrypted legal document, and performs hash operation on the encrypted legal document, the abstract information and the uplink time stamp to obtain a total hash value; of course, the total hash value is stored in the block header to reduce the data redundancy of each node;
s4, the supervision platform records the total hash value into a message reminding dynamic data set and chains the dynamic data set;
s5, after the ownership registration node receives the message reminding dynamic data set, checking the total hash value, and judging whether the summary information belongs to the current ownership registration node, specifically: the ownership registration node checks the total hash value through the Mercker tree, reads the summary information, judges whether the executed person and the property information are matched, and registers in the mechanism, if yes, the step S6 is executed; if the checking calculation is unsuccessful, namely the abstract information is not matched or does not belong to the current ownership organization, sending a seal checking information error notification to the court node which generates the legal documents, and recording and marking the uplink information for invalidation after the court node receives the notification.
S6, the current ownership registration node decrypts and analyzes the encrypted legal documents by using the private key thereof, and determines and executes the sealing sequence of the property according to the sequence of the uplink timestamps of the encrypted legal documents.
In this embodiment, in step S4:
each ownership registration node has unique ID identification information and publishes the ID identification information on a supervision platform;
the supervision platform forms a message reminding dynamic data group by the total hash value and the ID identification information; and reminding the ownership registration node by using the dynamic data group, and then carrying out corresponding decryption processing according to the total hash value.
In an embodiment, the step S6 further includes:
after the property in the first place is released, the property in the first place is removed from the preserving sequence of the executed property to form a new preserving sequence of the executed property, specifically: for example, the determined security order is ABCDE; if the property A is released, the legal document of the same case number is uplinked JA (with a time stamp), the JA is decrypted by the ownership registration node, the ownership registration node is confirmed to be behind the JA time stamp, and the BCDE serves as a new security sequence; if the property security of C in the sequence is released, the chain JC (with the timestamp) is released in the legal document of the same case number, after the JC is decrypted by the ownership registration node, the ownership registration node recognizes that the JC timestamp is reached, the new sequence is ABDE, AB is kept unchanged, and DE is sequentially promoted.
In this embodiment, in step S2, the court node encrypts the legal document with the preserved property by using an asymmetric encryption algorithm, and encrypts and links the legal document to the supervision platform by using the public key of the ownership registration node corresponding to the executed property.
In this embodiment, in step S1, the alliance chain employs a byzantine fault-tolerant algorithm consensus; because the alliance chain is used as one of the block chains, after the legal document information is marked with the timestamp, the legal document information is recorded in the alliance chain, a plurality of blocks in the alliance chain can be changed only when the post-preservation execution information needs to be tampered, and moreover, because of the strong consistency of the Byzantine fault-tolerant consensus algorithm, each node has information storage, and data forged by the node in time cannot be acknowledged by other nodes, so that the authenticity and the tamper-proof property of the whole timestamp are ensured, and the transparency and the accuracy of the preservation sequence are further ensured.
In this embodiment, in step S2, before encrypting and uploading the legal documents of property preservation, the court node determines whether its own network environment is trusted, if so, performs corresponding processing, and if not, stops current operation to wait for the next determination time, where the court node needs to determine the security of its own network environment, and performs encryption operation and uploading only when it is safe, and does not perform processing when it is not trusted, and performs security detection on the network environment of the court node according to a set time unit, for example, once every 5S detection or once every 10 minutes detection, which may be set by itself.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
