s202, receiving registration information of a first network node to a social network, and auditing the registration information by other network nodes;
s204, when the verification is passed, encrypting and storing the registration information to any network node of the social network so as to carry out identity authentication and identification according to the registration information;
specifically, the social network Etherhouse blockchain is the underlying platform. The method is characterized in that a user is allowed to operate a node on own equipment to access a network, the node is interconnected with the node, user information is stored in the network node in an encrypted form to form a distributed cloud, and effective data of the node can be obtained only by mastering keys (a blind signature strategy, a multiple signature strategy and a threshold signature strategy) according to a block chain technology. The method comprises the steps that a user applies for a network identity from a social network identity issuing mechanism by using real identity information, the issuing mechanism carries out identity identification according to an issuing network, the network identity is a string of random numerical values, the issued network identity can be recorded, an Etheng platform user can establish a final abstract basic layer, a block chain with a built-in complete graphic programming language can be established, any person can establish contracts and decentralized applications, freely-defined ownership rules, transaction modes and state conversion functions are set in the contracts, and when the user registers the network identity with the real identity, triple state conversion functions can be randomly set according to user registration information and stored on a network node.
It should be noted that, based on the triple state transition function of the ethernet, it is specifically checked whether the format of the id to be recognized is correct (i.e., has a correct value), whether the signature is valid, whether the sending address is correct, and whether the random number matches the random number of the sender account. If not, an error is returned.
When a user operates a network node and joins a social network, primary identity recognition is carried out on the user according to encrypted information and a state conversion function during registration of the user, the primary identity recognition comprises the steps of verifying the registration information and whether the private key of the hash function is mastered by the user, when the user uses a registered network identity to carry out transaction interaction in the social network, the stored identity information of the user is required to reach a credible standard, carrying out secondary identity recognition on the identity of the user and encrypting the interactive information, and at the moment, the user is verified whether the private key of a double state conversion function is mastered by the user.
S206, when the reporting information from any first network node is received, other online network nodes in the social network verify and identify the first network node identity, and the reporting information comprises the reported second network node identity;
specifically, when there is a network identity report, that is, when the identity of a certain network node indicates that the identity of another network node is suspect, the other network nodes (generally, the closest network node) on line in the social network perform third identity recognition on the network identity of the reported network node, and the user needs to master the third triple private key, so that the false account or illegal report can be effectively prevented.
If the verification identification is passed in S206, executing S208, and when the first network node identity identification passes the verification identification, broadcasting a second network node identity identification in the social network all over the network;
s210, when the second network node identity is broadcasted in the social network in the whole network, other network nodes verify and identify the second network node identity;
s212, when the second network node identity identification is not verified and identified, feeding back problem reporting information to the first network node;
specifically, the social network adopting the social information reporting method of the invention expands the identity verification identification thereof, so that the intelligent contract is realized to a certain extent, the user can perform normal social activities only by collecting three keys, and the effectiveness of social reporting is improved in the application of the social network by multiple signatures.
S214, judging whether the number of the feedback report information received by the first network node is greater than a second preset threshold value;
if the judgment of the step S214 is yes, the step S216 is executed, the second network node identity is determined to be frozen, the second network node identity is broadcasted in the social network all over the network, and the related data information of other network nodes is updated;
if the determination in S214 is no, then S218 is performed, and it is determined whether the number of the feedback problem report information received by the first network node is greater than or equal to a first preset threshold;
if the determination in S218 is yes, then S220 is executed, and the identity of the second network node is determined to be a suspected network identity, and is stored in an adjacent network node;
s222, when the suspected network identity is logged in again and passes the verification and identification, the reported prompt information is sent;
if the verification identification in the step S206 is not passed, executing step S224, when the first network node identity identification fails, recording that the first network node identity identification is a false network identity identification, storing the false network identity identification to an adjacent network node, and reducing the preset reporting limit times of the first network node identity identification within a preset time period;
s226, judging whether the preset reporting limit times are less than or equal to zero;
if the determination at S226 is yes, S228 is performed to determine to freeze the first network node identifier, and broadcast the first network node identifier all over the network in the social network, and update the related data information of other network nodes.
It should be noted that each report generates a block, each block containing a timestamp, a random number, a reference to the previous block (i.e., hash), and all the report lists that occurred since the previous block was generated, thus creating a continuously growing chain of report list blocks over time that are continuously updated and can represent the trustworthiness rating of the user, thus forming a valid chain of report etherhouse blocks. Effective processing of the report information is realized by using an ether house block validation algorithm, as shown in fig. 4, specifically, whether a last block referenced by a block exists and is effective is checked; checking whether the time stamp of the block is larger than the last block referenced and is less than 15 minutes; checking whether the block sequence number, a random number, a reference (i.e., hash) to the previous block, all report lists occurring since the previous block was generated, and a preset report limit number are valid; checking whether the workload of the block proves to be effective or not, if the workload of the reserved block is exceeded, more strict limitation is needed to the reporting condition, and S0 is assigned to be the STATE of the last block; tx is assigned as a reporting list of blocks, with a total of n reports. For i belonging to 0 … … n-1, a state transition S [ i +1] ═ APPLY (S [ i ], Tx [ i ]) is performed. If any one conversion has an error, or the program spends more than a limit to execute, returning an error; assigning S _ FINAL with S [ n ], checking whether S _ FINAL is the same as STATE; if so, the block is valid. Otherwise, the block is invalid.
The effective processing of the report information is realized by utilizing an EtherFang block confirmation algorithm, the state is stored in a tree structure, and only a small part of the tree structure needs to be changed when each block is added. Thus, in general, most of the tree structure of two adjacent blocks should be the same, and therefore storing data once, can be referenced twice with a pointer (i.e., a sub-tree hash). This is achieved by a Tree structure called a Patricia Tree, which includes modifications to the concept of the mercker Tree, allowing not only the nodes to be changed, but also the nodes to be inserted and deleted. In addition, since all the state information is part of the last chunk, there is no need to store the entire chunk history, which is calculated to provide a 10-20 times savings in storage space.
The technical scheme of the invention is explained in detail by combining the drawings, and the invention provides a social information reporting method based on a block chain and a social information reporting device based on the block chain.
