Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with one or more embodiments of the present specification. Rather, they are merely examples of apparatus and methods consistent with certain aspects of one or more embodiments of the specification, as detailed in the claims which follow.
It should be noted that: in other embodiments, the steps of the corresponding methods are not necessarily performed in the order shown and described herein. In some other embodiments, the method may include more or fewer steps than those described herein. Moreover, a single step described in this specification may be broken down into multiple steps for description in other embodiments; multiple steps described in this specification may be combined into a single step in other embodiments.
Blockchains are generally divided into three types: public chain (Public Blockchain), private chain (PrivateBlockchain) and alliance chain (Consortium Blockchain). Furthermore, there may be a combination of the above types, such as private chain + federation chain, federation chain + public chain, and so on.
Among them, the most decentralized is the public chain. The public chain is represented by bitcoin and ether house, and participants (also called nodes in the block chain) joining the public chain can read data records on the chain, participate in transactions, compete for accounting rights of new blocks, and the like. Moreover, each node can freely join or leave the network and perform related operations.
Private chains are the opposite, with the network's write rights controlled by an organization or organization and the data read rights specified by the organization. Briefly, a private chain may be a weakly centralized system with strict restrictions on nodes and a small number of nodes. This type of blockchain is more suitable for use within a particular establishment.
A federation chain is a block chain between a public chain and a private chain, and "partial decentralization" can be achieved. Each node in a federation chain typically has a physical organization or organization corresponding to it; the nodes are authorized to join the network and form a benefit-related alliance, and block chain operation is maintained together.
Based on the basic characteristics of a blockchain, a blockchain is usually composed of several blocks. The time stamps corresponding to the creation time of the block are recorded in the blocks respectively, and all the blocks form a time-ordered data chain according to the time stamps recorded in the blocks strictly.
The real data generated by the physical world can be constructed into a standard transaction (transaction) format supported by a block chain, then is issued to the block chain, the node equipment in the block chain performs consensus processing on the received transaction, and after the consensus is achieved, the node equipment serving as an accounting node in the block chain packs the transaction into a block and performs persistent evidence storage in the block chain.
The consensus algorithm supported in the blockchain may include:
the first kind of consensus algorithm, namely the consensus algorithm that the node device needs to contend for the accounting right of each round of accounting period; consensus algorithms such as Proof of Work (POW), Proof of equity (POS), Proof of commission rights (DPOS), etc.;
the second kind of consensus algorithm, namely the consensus algorithm which elects accounting nodes in advance for each accounting period (without competing for accounting right); for example, a consensus algorithm such as a Practical Byzantine Fault Tolerance (PBFT) is used.
In a blockchain network employing a first type of consensus algorithm, node devices competing for billing rights can execute a transaction upon receipt. One of the node devices competing for the accounting right may win in the process of competing for the accounting right in the current round, and become an accounting node. The accounting node may package the received transaction with other transactions to generate a latest block and send the generated latest block or a block header of the latest block to other node devices for consensus.
In the block chain network adopting the second type of consensus algorithm, the node equipment with the accounting right is agreed before accounting in the current round. Thus, the node device, after receiving the transaction, may send the transaction to the accounting node if it is not the accounting node of its own round. For the accounting node of the current round, the transaction may be performed during or before packaging the transaction with other transactions to generate the latest block. After generating the latest block, the accounting node may send the latest block or a block header of the latest block to other node devices for consensus.
As described above, regardless of which consensus algorithm is used by the blockchain, the accounting node of the current round may pack the received transaction to generate the latest block, and send the generated latest block or the block header of the latest block to other node devices for consensus verification. If no problem is verified after other node equipment receives the latest block or the block header of the latest block, the latest block can be added to the tail of the original block chain, so that the accounting process of the block chain is completed. The transaction contained in the block may also be performed by other nodes in verifying the new block or block header sent by the accounting node.
In practical applications, whether public, private, or alliance, it is possible to provide the functionality of a smart contract (Smartcontract). An intelligent contract on a blockchain is a contract on a blockchain that can be executed triggered by a transaction. An intelligent contract may be defined in the form of code.
Taking an Etherhouse as an example, a user is supported to create and call some complex logic in the Etherhouse network. The ethernet workshop is used as a programmable block chain, and the core of the ethernet workshop is an ethernet workshop virtual machine (EVM), and each ethernet workshop node can run the EVM. The EVM is a well-behaved virtual machine through which various complex logic can be implemented. The user issuing and invoking smart contracts in the etherhouse is running on the EVM. In fact, the EVM directly runs virtual machine code (virtual machine bytecode, hereinafter referred to as "bytecode"), so the intelligent contract deployed on the blockchain may be bytecode.
After Bob sends a Transaction (Transaction) containing information to create a smart contract to the ethernet network, each node can execute the Transaction in the EVM, as shown in fig. 1. In fig. 1, the From field of the transaction is used To record the address of the account initiating the creation of the intelligent contract, the contract code stored in the field value of the Data field of the transaction may be bytecode, and the field value of the To field of the transaction is a null account. After the nodes reach the agreement through the consensus mechanism, the intelligent contract is successfully created, and the follow-up user can call the intelligent contract.
After the intelligent contract is established, a contract account corresponding to the intelligent contract appears on the block chain, and the block chain has a specific address; for example, "0 x68e12cf284 …" in each node in fig. 1 represents the address of the contract account created; the contract Code (Code) and account store (Storage) will be maintained in the account store for that contract account. The behavior of the intelligent contract is controlled by the contract code, while the account storage of the intelligent contract preserves the state of the contract. In other words, the intelligent contract causes a virtual account to be generated on the blockchain that contains the contract code and account storage.
As mentioned above, the Data field containing the transaction that created the intelligent contract may hold the byte code of the intelligent contract. A bytecode consists of a series of bytes, each of which can identify an operation. Based on the multiple considerations of development efficiency, readability and the like, a developer can select a high-level language to write intelligent contract codes instead of directly writing byte codes. For example, the high-level language may employ a language such as Solidity, Serpent, LLL, and the like. For intelligent contract code written in a high-level language, the intelligent contract code can be compiled by a compiler to generate byte codes which can be deployed on a blockchain.
Taking the Solidity language as an example, the contract code written by it is very similar to a Class (Class) in the object-oriented programming language, and various members including state variables, functions, function modifiers, events, etc. can be declared in one contract. A state variable is a value permanently stored in an account Storage (Storage) field of an intelligent contract to save the state of the contract.
As shown in FIG. 2, still taking the Etherhouse as an example, after Bob sends a transaction containing the information of the calling intelligent contract to the Etherhouse network, each node can execute the transaction in the EVM. In fig. 2, the From field of the transaction is used To record the address of the account initiating the intelligent contract invocation, the To field is used To record the address of the intelligent contract invocation, and the Data field of the transaction is used To record the method and parameters of the intelligent contract invocation. After invoking the smart contract, the account status of the contract account may change. Subsequently, a client may view the account status of the contract account through the accessed block link point (e.g., node 1 in fig. 2).
The intelligent contract can be independently executed at each node in the blockchain network in a specified mode, and all execution records and data are stored on the blockchain, so that after the transaction is executed, transaction certificates which cannot be tampered and lost are stored on the blockchain.
A schematic diagram of creating an intelligent contract and invoking the intelligent contract is shown in fig. 3. An intelligent contract is created in an Ethernet workshop and needs to be subjected to the processes of compiling the intelligent contract, changing the intelligent contract into byte codes, deploying the intelligent contract to a block chain and the like. The intelligent contract is called in the Ethernet workshop, a transaction pointing to the intelligent contract address is initiated, the EVM of each node can respectively execute the transaction, and the intelligent contract code is distributed and operated in the virtual machine of each node in the Ethernet workshop network.
Referring to fig. 4, fig. 4 is a flowchart illustrating a method for forensics based on a blockchain according to an exemplary embodiment. As shown in fig. 4, the method applied to the client may include the following steps:
In an embodiment, when a user accesses a target web page, if it is found that the content in the web page has an infringement problem, the user may mark the content having the infringement problem on the web page (hereinafter, referred to as infringement content) so as to inform the forensics server that the marked content has the infringement problem, and the forensics server obtains the infringement content of the target web page and issues the infringement content to a block chain for forensics.
For the process of marking infringed content by a user, since the user usually accesses a webpage through a browser, a plug-in program loaded on the browser can be developed for marking infringed content. In other words, the client applied in the present embodiment is a plug-in installed in a browser. Then, when the user has a requirement for marking the infringement content, the plug-in program carried in the browser can be directly called to mark the infringement content, and the evidence collection is not required to be carried out in other modes similar to photographing, screenshot and the like, so that the evidence collection efficiency can be effectively improved. For example, a user may issue a call instruction for a plug-in to a browser, and the browser executes the plug-in to detect a content tagging operation of the user for a target web page after receiving the call instruction.
Of course, the plug-in for marking infringement content can be developed by adopting various programming languages, and the specific type of the plug-in can be flexibly selected according to actual requirements. For example, plug-ins of file types such as ocx, dll, cab, exe, etc. may be used, and one or more embodiments of the present disclosure are not limited thereto.
Accordingly, referring to fig. 5, fig. 5 is a flowchart of a block chain-based infringement forensics method according to an exemplary embodiment. As shown in fig. 5, the method applied to the forensics server may include the following steps:
In this embodiment, the marking process may refer to the marking process in the embodiment shown in fig. 4, and is not described herein again.
In this embodiment, the content of some web pages may need to be accessed after the user logs in. Therefore, when the user finds that the content in the accessed webpage (after login is successful) has an infringement problem, an infringement forensics request can be generated to instruct the forensics server to carry out forensics. When the infringement evidence-obtaining request is generated, besides the access address of the target webpage and the identification information of the infringement content, the login information aiming at the target webpage can be added in the infringement evidence-obtaining request. Then, after receiving the infringement and forensics request, the forensics server can log in the target webpage according to the login information contained in the infringement and forensics request, and then obtain the infringement content corresponding to the identification information from the target webpage after successful login, so that the problem that the infringement content cannot be obtained due to unsuccessful login is avoided.
In this embodiment, the web page generally supports a function of modifying content on the web page, and there is a possibility that an infringing party (i.e. a publisher of the infringing content on the target web page) modifies the infringing content during the process of forensics or during the process of determining infringement subsequently. Therefore, the infringement content marked by the user or the check value of the infringement content can be added to the infringement forensics request, so that the forensics server can acquire the infringement content actually marked by the user.
In one case, the infringement request includes infringement content, and the forensics server may determine whether the acquired infringement content is consistent with the infringement content included in the infringement request after acquiring the infringement content corresponding to the identification information, and execute an operation of storing the infringement content when the acquired infringement content is consistent with the infringement content included in the infringement request.
In another case, the request for obtaining evidence of infringement includes a check value of the infringement content, and then the server for obtaining evidence may calculate the check value of the acquired infringement content after acquiring the infringement content corresponding to the identification information, determine whether the acquired check value of the infringement content is consistent with the check value included in the request for obtaining evidence of infringement, and execute an operation of storing the infringement content when the acquired check value of the infringement content is consistent with the check value included in the request for obtaining evidence of infringement.
As can be seen from the above embodiments, when a user finds that an accessed webpage is infringed, the user can mark the content with infringement problems on the webpage to notify the forensics server, and then the forensics server can obtain the infringement content and issue the obtained infringement content as an infringement tracing evidence of an infringed party to a block chain for forensics, thereby completing the process of infringement and forensics.
Since the infringement content is issued to the block chain for storage and verification, and a complete infringement content is recorded in each block chain node, even if a certain node has a data damage problem, the integral data integrity is not influenced; meanwhile, the non-tamper property and the traceability of the block chain storage data are fully utilized, so that lawless persons are prevented from modifying the infringement content maliciously, the safety of the recorded infringement content is ensured, and the traceability can be carried out.
Furthermore, the process of marking infringed content can be completed by the user in cooperation with a plug-in program loaded on the browser. Specifically, when a user accesses a webpage through a browser, if the webpage is found to have an infringement problem, the process of obtaining evidence can be completed by directly using a plug-in program loaded by the browser, so that the evidence obtaining efficiency is effectively improved.
For ease of understanding, the infringement forensic aspects of the present description are described in detail below with reference to examples and figures 6-7.
As shown in fig. 6, the forensics process is accomplished by interaction between the browser 61 and the forensics server 62, and may include the following steps:
in step 602, the user accesses the target web page a through the browser 61.
In this embodiment, the browser 61 is loaded with an infringement mark plug-in, and when the user finds that the currently accessed webpage has an infringement problem, the infringement mark plug-in on the browser can be directly called to mark infringement content on the target webpage a.
In step 604, the infringement tagging plugin detects the content tagging operation of the user for the target webpage A.
As shown in fig. 7, the browser 61 is installed with an infringement sign plug-in, which can be triggered and started by an "infringement evidence-obtaining sign" button in the figure. For example, the user may invoke the infringement markup plug-in by mouse-clicking on an "infringement forensic mark" button, and when the browser 61 detects a click operation for the button, the infringement markup plug-in is executed. And when the infringement marking plug-in is triggered to be executed, each page area on the target webpage A is changed into a selectable state for a user to select and mark. For example, the target page a includes page areas a 1-a 6, and the user can check the page area including the infringing content by using a mouse to complete the marking of the infringing content.
At step 606, the infringement marking plugin generates an infringement forensic request.
In this embodiment, the content of some web pages may need to be accessed after the user logs in. Therefore, the access address of the target webpage, the login information aiming at the target webpage and the identification information of the infringement content can be added in the infringement and evidence-obtaining request, so that the evidence-obtaining server can firstly access the target webpage according to the access address and then log in the target webpage according to the login information, and therefore the infringement content (namely the infringement content marked by the user) corresponding to the identification information is successfully obtained. For example, the access address may be a web page address of the target web page, the login information may be a cookie for logging in the target web page, and the identification information may be an identifier of a page area selected by the user.
In addition, the web page generally supports the function of modifying the content on the web page, and there is a possibility that an infringing party (i.e. a publisher of the infringing content on the target web page) modifies the infringing content during the process of obtaining evidence or during the process of subsequently determining infringement. Therefore, the infringement content marked by the user or the check value of the infringement content can be added to the infringement forensics request, so that the forensics server can acquire the infringement content actually marked by the user. Taking the added Check value as an example, the infringement content may be calculated by using algorithms such as MD5(Message-Digest Algorithm), CRC (Cyclic Redundancy Check), LRC (Longitudinal Redundancy Check), hash calculation (hash), and the like, so as to obtain the Check value.
At step 608, the infringement branding plug-in sends an infringement forensics request to forensics server 62.
At step 610, forensics server 62 accesses target web page a to obtain infringement content.
In the above example, the forensics server 62 accesses the target webpage a according to the website included in the infringement forensics request, and logs in the target webpage a according to the cookie included in the infringement forensics request, so as to obtain the corresponding page content, i.e. the infringement content, according to the identifier.
At step 612, the forensics server 62 verifies the infringement content.
In the above example, assuming that the infringement marker plug-in unit calculates a first check value by using the hsah algorithm and adds the first check value to the infringement evidence obtaining request, the evidence obtaining server 62 obtains the infringement content and then performs hsah calculation on the obtained infringement content by using the same hash algorithm to obtain a second check value. If the first check value is consistent with the second check value, go to step 614; otherwise, returning a corresponding prompt message to the infringement marking plug-in. For example, the prompt message may be "the marked content does not conform to the actual content of the web page," or "the infringing content of the web page has been modified," or the like.
In step 614, the forensics server 62 issues the infringement content to the blockchain B for forensics.
In this embodiment, the forensics server 62 is used as a client of the blockchain and is in butt joint with the blockchain node, and when the verification result is consistent, the forensics server 62 packages a transaction for storing the forensics content and submits the transaction to the blockchain node, so that the blockchain node issues the forensics content to the blockchain for forensics after passing the consensus.
According to the embodiment, based on the evidence obtaining form of the browser plug-in, a large number of users who visit the webpage under the line are submitted to the webpage infringement reporting, and the infringement content is linked up through the evidence obtaining server to solidify the infringement evidence, so that the effective record of the ubiquitous infringement behaviors of the online webpage is completed, and the evidence obtaining efficiency is improved.
It should be noted that, the infringement forensic scheme in this specification may further send an infringed party corresponding to the infringed content and corresponding infringed content to the forensic server. As an exemplary embodiment, the forensic server may be instructed to obtain the infringed content in the infringed web page and distribute the infringed content to the blockchain for evidence of the infringed content in the same manner as described above for the forensics of the infringed content. For example, the infringed content is also marked by the user, data such as an access address of a target webpage (i.e., an infringing webpage), login information of the target webpage, identification information of the infringing content, and an access address of the infringed webpage, login information of the infringing webpage, identification information of the infringed content, etc. may be recorded in the infringing and forensics request, and then the forensics server may obtain the infringing content and the infringed content according to the data, thereby associating the infringing content and the infringed content (both together serving as infringement evidence) for infringement determination.
Further, an intelligent contract may be deployed on the blockchain for determining whether infringing content and infringed content associated with the proofs on the blockchain actually constitute infringement behavior. For example, an infringement determination contract may be developed in which infringement determination logic is declared for verifying that the infringement evidence (infringing content and corresponding infringed content) meets infringement conditions. The infringement condition may be flexibly set according to actual requirements, and one or more embodiments of the present disclosure are not limited thereto.
Based on the deployment of the infringement judgment contract, the infringement marking plug-in can monitor data stored on the block chain, when it is monitored that the data stored on the block chain has infringement evidence for the target webpage, an infringement judgment transaction for the target webpage is created (the content of a to field of the infringement judgment transaction is a contract address of the infringement judgment contract, namely the transaction is used for calling the infringement judgment contract), the infringement judgment transaction is submitted to the block link points, so that the block link points call the infringement judgment contract, infringement judgment logic stated in the infringement judgment contract is used for checking whether the infringement evidence corresponding to the target webpage meets infringement conditions or not, and an infringement judgment result for the target webpage is generated according to a checking result. Therefore, through the evidence obtaining mode and the infringement judging mode of the specification, the user can timely obtain evidence and report when browsing a webpage and finding an infringement behavior, the infringement content is linked to solidify infringement evidence, and the infringement judgment is completed through an intelligent contract, so that the user operation can be simplified, and the evidence obtaining efficiency and the infringement judging efficiency can be improved.
