In the law enforcement and case handling process, the electronic evidence is given a timestamp, the integrity of the data is verified through a hash value, the electronic evidence is encrypted by adopting an asymmetric encryption technology in the transmission process to ensure the transmission safety, and the authenticity and the safety of the data are fully ensured. Meanwhile, the evidence storage mode based on the block chain is distributed storage, so that the electronic evidence is allowed to be shared by a plurality of link nodes for law enforcement and case handling, the time cost for evidence collection is reduced, and the efficiency of collaborative case handling is improved.
As shown in fig. 1, the invention provides a collaborative law enforcement case handling method based on a blockchain, which ensures justice and standardization in the case handling and law enforcement process and the trueness and credibility of evidences of each link through a blockchain technology, and specifically comprises the following steps:
s1: the case information of the nodes of the law enforcement and case handling nodes is collected, and is packaged into a law enforcement and case handling data packet through an encryption algorithm and uploaded to a law enforcement and case handling platform;
s2, the law enforcement case handling platform carries out block registration on the law enforcement case handling data packet, and a timestamp is added on the law enforcement case handling data packet to form block file information;
a law enforcement and case handling node is a law enforcement and case handling block, each law enforcement and case handling block is provided with a time stamp, the time stamp forms a time block independently, the time block is in strong correlation with the law enforcement and case handling block transversely, meanwhile, the time block and the law enforcement and case handling block are respectively formed into a block longitudinally, and the block is correlated with the previous block, so that all the law enforcement and case handling blocks are linked together to form a law enforcement and case handling double chain.
S3: after the authentication of each law enforcement case handling node is successful, receiving the block file information of the last law enforcement case handling node, and performing S1 and S2 operations on the case information of the node to finish uploading the case information;
s4: and forming a full-period law enforcement case transaction book according to the block file information of all the law enforcement case transaction nodes.
In a specific application, as shown in fig. 2-3, the block file information is established in an ideal manner, in which case full-period case handling information uplinks are performed, and case records uplinks are performed from alarm receiving and case setting, and each node sequentially and continuously supplements case information data files according to a case handling process, and the case information data files are organized into a series of blocks until the case is successfully finalized, so as to form a bill of the case. Each block has all case information of the present case.
When a certain law enforcement and case handling node needs other nodes to supplement case information or actively supplement the case information of the node, the node needing to supplement the case information performs identity verification and system login according to the unique ID, after the case information is supplemented, all nodes on a block chain are updated according to the updated block archive information of the node, and a subsequent new process of the node is initiated.
In specific application, in the process of initially forming a full-period law enforcement and case handling book, a certain law enforcement node needs to supplement case information, and two conditions are considered to exist:
1. when the latter law enforcement node needs the former law enforcement node to supplement the case handling information in the case handling process, after the corresponding required node receives the requirement, the former law enforcement node responds to the requirement to supplement the case information of the former law enforcement node, and the law enforcement nodes on all block chains synchronize the case information;
specifically, as shown in fig. 4-5, when the following node needs the previous node to supplement the evidence, the update status of the block archive information requires U3 to supplement the case information of the law enforcement and case handling node, and U3 supplements the case information at its node, in this process, all the law enforcement and case handling nodes receive the request of U4, and synchronize to each law enforcement and case handling node after U3 supplements the case information, thereby completing the update of the block archive information of the whole block chain.
2. When one law enforcement node actively supplements the case information of the node, the case information which needs to be supplemented is uploaded, at the moment, the work of the next law enforcement node at an interval is temporarily stopped, and after the adjacent law enforcement node of the supplement node obtains new case information, the next law enforcement node at the interval conducts the case handling process of the corresponding node according to the new case information again, so that the case information in the whole case flow is guaranteed to be real and effective, and the basis of each law enforcement node is the conclusion of the latest information.
Specifically, as shown in fig. 6-7, when the previous law enforcement node actively supplements the evidence, the update status of the block file information is that the law enforcement and case handling node U2 actively supplements the evidence, the U4 and the following law enforcement and case handling nodes stop the work of the law enforcement and case handling nodes after obtaining the information, the U2 updates the case information of the law enforcement and case handling nodes to the whole block chain, and after the U3 completes the case information supplementation of the nodes, the subsequent law enforcement and case handling nodes restart the work according to the latest updated law enforcement and case handling information.
The forming process of the whole-period law enforcement and case handling account book comprises the following steps: through the design of a multi-node storage server and distributed storage, a physical space for distributed law enforcement accounting of a block chain of law enforcement officers is established, and distributed accounting is performed by adopting an encryption hash algorithm and secret key signature encryption.
In the specific application, the invention forms a full-period law enforcement and case handling book, establishes a distributed law enforcement and case handling personnel blockchain law enforcement and accounting physical space by means of a multi-node distributed server or a distributed storage type design, performs distributed accounting, performs holographic mapping on the full-period law enforcement and case handling records, and forms the full-period law enforcement and case handling book by means of an encryption hash algorithm and secret key signature encryption.
The whole period law enforcement and case handling account book comprises: case, law enforcement and case handling node data, law enforcement and case handling circulation data and case settlement information.
In the specific application, according to the law enforcement and case handling process, the block data files are disclosed to all collaborative case handling departments on the chain, and then the case handling process is automatically recorded on the process chain until the case is settled, so that a full-period law enforcement and case handling book is formed.
The whole period law enforcement and case handling book comprises: the case information comprises case occurrence time, case occurrence place, case designer, case related articles, case related vehicles, case surrounding environment, case name, case contact mode, case reporting place, case original record, case original recorder and the like; the law enforcement and case handling node data specifically comprises field images, field audio, field record, case visiting record, case surrounding environment information, law enforcement and case handling node case handling person information, case handling person research and judgment information and the like; the law enforcement and case handling circulation data comprises node users, circulation nodes, circulation time, case handling recording system logs and the like; the final information includes final time, final location, final participator, final conclusion, final opinion, and electronic file.

In the law enforcement and case handling process, the system further comprises a supervision chain, wherein the supervision chain can set whether the case handling information of the existing law enforcement nodes is disclosed or not after the law enforcement and case handling data packet is uploaded by each law enforcement and case handling node, and when the case information is not disclosed by more than 51% of consent on the block chain, the case information of the law enforcement and case handling node is not automatically opened to the outside.
In a specific application, a supervision chain is set by rules, and a machine automatically judges whether data in a law enforcement process has an illegal condition. The specific rule is as follows: and arranging a disclosure button at a case handling law enforcement node, after each law enforcement and case handling personnel finishes the record of the law enforcement and case handling business at the node, uploading and packaging case information, selecting whether to agree to disclose the case information content of the node, if agreeing to disclose, clicking to agree, if not operating, defaulting to not agree to disclose the case content, and meanwhile, other law enforcement and case handling nodes can select whether to disclose the case information of the node to form a supervision chain. The block chain can be opened to the outside when more than 51% of the block chain agrees to the public, otherwise, the block chain cannot be opened to the outside.
If the information leakage condition occurs, the block chain can immediately find the leakage link and the leakage person, thereby fundamentally ensuring the fairness and justice of the law enforcement and case handling process.
In the process of law enforcement and case handling, the system further comprises an early warning chain, wherein the early warning chain is used for risk early warning of case handling trust, and early warning notification is carried out on all nodes through a specified early warning rule.
The early warning rules include:
1. when the trial modification times of the submitted node case handling records exceed a certain preset value, carrying out all-node early warning notification; in a specific application, the preset value is greater than or equal to 3.
2. After the number of times of supplementing the submitted node case handling records exceeds a preset value, early warning notification is carried out on all nodes during each supplementing; in a specific application, the preset value is greater than or equal to 5.
3. Carrying out abnormal behavior operation on the case handling node information, wherein the abnormal behavior operation comprises but is not limited to copying, pasting and accessory downloading, and carrying out early warning notification on all nodes;
4. when the case handling time of a certain node is larger than or smaller than the preset case handling time range. And carrying out early warning notification on all nodes.
In specific application, under the blockchain technology, each case-handling law enforcement node can verify the authenticity and integrity of information content and the normative of case-handling procedures, so that the reliability and the trueness of the case-handling process of law enforcement are ensured, if information is falsified, a person can take care of the case, and when an exception is found, early warning can be timely performed, so that the trust risk in the case-handling process is reduced.
The specific early warning rules include:
1) and prohibiting modification of the case information submitted on the block chain, allowing modification evidence to be carried out on the original node case handling process and stopping account sealing to the original record and subsequent circulation when various trial modifications are carried out on the submitted case handling information, and carrying out all-node early warning notification when the modification of a certain node exceeds 3 times.
2) When the nodes which submit case information are supplemented for more than 5 times, early warning notification can be carried out on all the nodes during each supplement.
3) And carrying out abnormal operation on the uploaded case information, wherein the abnormal operation comprises but is not limited to copying, pasting, accessory downloading and the like, and carrying out early warning notification on all nodes.
4) The case handling time of each law enforcement case handling node in the block chain is set to a certain preset value, and when the case handling time of a certain law enforcement case handling node is too long or too short, early warning notification can be carried out on all nodes.
In the law enforcement and case handling process, the system further comprises an information sharing chain, wherein the information sharing chain is composed of all the law enforcement and case handling nodes, all the law enforcement and case handling nodes serve as independent information sharing individuals, and information resource sharing is achieved by combining an information contribution catalog and an information sharing resource library through a data encryption hash algorithm.
In a specific application, in the process of law enforcement and case handling, by using the technical characteristics of decentralized block chains, data resources in different fields of law enforcement and case handling are integrated into one block chain, an information contribution catalog and an information sharing resource library are established, each type/each piece/each item of population data, case data, electronic material evidence data, perception data, text record data and the like are listed in the resource library, each law enforcement and case handling node is used as an independent information sharing individual, and each type/each piece/each item of data information sharing chain is formed by using a sharing database through a data encryption hash algorithm in combination with the authority of data information sharing, so that information resource sharing is realized.
And the case information is encrypted through an asymmetric encryption technology in the transmission process among the law enforcement case nodes, and the law enforcement case nodes receiving the case information verify the integrity of data by comparing hash values. The safety and the integrity of the information in the whole law enforcement and case handling process are improved, so that the fairness of law enforcement and case handling is better improved.
In the invention, each law enforcement and case handling node carries out curing operation on the algorithm program through hash value verification.
In a specific application, in order to prevent the algorithm program from being tampered, the algorithm program in the method is solidified through a block chain, so that the algorithm program is prevented from being tampered.
As shown in FIG. 8, the hash value verification is performed among the various law enforcement and case handling nodes to determine that the underlying algorithm program is not modified, thereby fundamentally ensuring the security and integrity of the data.
In the whole law enforcement and case handling process, the block chain technology can be used for encrypting through an encryption hash algorithm and a signature private key, and data is prevented from being tampered and leaked. Meanwhile, the key sensitive information such as identity information, criminal information, entry and exit information and the like of the suspect is encrypted by taking the chain, and the information safety is ensured.
And each law enforcement node automatically triggers an intelligent contract in the cooperative case enforcement node to perform each operation on the blockchain. The concept of intelligent contracts dates back to 1994, almost concurrently with the internet (world wide web). The cryptologist, Nick Szabo (Nick Szabo), who was widely praised because of the underlying foundation made by bitcoin, first proposed the term "smart contracts". Essentially, the working principle of these automatic contracts is similar to if-then statements of other computer programs. Smart contracts interact with real-world assets only in this manner. When a pre-programmed condition is triggered, the intelligent contract executes the corresponding contract clause.
The application of intelligent contracts in law enforcement methods is illustrated below:
firstly, after the information record of each law enforcement node is finished, an independent encryption type law enforcement case handling data packet is generated and serves as a circulated object and is pushed to the foreground of a law enforcement case handling platform; secondly, the law enforcement case handling platform carries out block registration on the actions of submitting law enforcement case handling records of the law enforcement case handling node initiator, and then the initiator is loaded. And then, the law enforcement case platform performs block registration on the law enforcement case record action of the receiving upper node of the law enforcement case new node receiver, namely, the receiver receiving pretreatment is completed. And then, the law enforcement and case handling platform verifies the initialized and preset goods receiving business process of the receiver in advance, and if the law enforcement and case handling platform is adaptive, the receiver formally receives goods. And finally, the law enforcement and case handling platform realizes blocking data solidification of case information circulation behaviors through an encryption hash algorithm, so that multi-node law enforcement and case handling block chain bookkeeping is realized.
The intelligent cooperation based on the block chain technology innovatively puts forward 'double-chain' and 'multi-chain' in law enforcement and case handling. Each law enforcement transaction block carries a time stamp, the time stamp forms a 'time block' independently, the 'time block' is in strong correlation with the 'law enforcement transaction block' transversely, meanwhile, the 'time block' and the 'law enforcement transaction block' also form respective blocks longitudinally, and the block is correlated with the previous block, so that all the law enforcement transaction blocks are linked together to form a 'double chain' of law enforcement transactions. Meanwhile, a supervision chain, an early warning chain and an information sharing chain are creatively provided in the aspects of supervision, early warning and information sharing of law enforcement and case handling "
