With continued reference to FIG. 2, a flow 200 of one embodiment of a method for processing information in accordance with the present disclosure is shown. The method for processing information comprises the following steps:
In this embodiment, an executing entity (e.g., the evidence storing device 104 shown in fig. 1) of the method for processing information may obtain the evidence to be stored sent by the user terminal and information indicating a data provider (e.g., the data provider 106 shown in fig. 1) to which the evidence to be stored is to be stored, in response to receiving an evidence storage request sent by the user terminal (e.g., the user terminals 101, 102, 103 shown in fig. 1) through a wired connection manner or a wireless connection manner. The user side is a terminal used by a user. The user can use the user terminal to send an evidence storage request to the execution main body. The evidence storage request is used for requesting storage of the evidence acquired by the user. The evidence to be stored is the evidence which is acquired by the user and is to be stored. Evidence is data that is used to prove some fact. As an example, the evidence to be stored may be data that proves the fact that a blogger released a rumor.
It should be noted that, here, the evidence to be stored may be electronic evidence that can be transmitted in electronic communication. Specifically, as an example, the evidence to be stored may be electronic text, images, voice, video, and the like.
In this embodiment, the evidence to be stored may be evidence obtained from a certain data provider by a user using a user side. As an example, the evidence to be stored may be a screenshot obtained from the "XX microblog" by the user using the user side. Here, the "XX microblog" is a data provider of the evidence to be stored.
In this embodiment, while the user uses the user side to send the evidence to be stored, information indicating the data provider of the evidence to be stored may be sent, so that the execution main body interacts with the data provider indicated by the information in the subsequent step. Here, the information indicating the data provider of the evidence to be stored may specifically be information selected by the user from a plurality of pieces of information indicating the data provider, which are predetermined by the user side, or information input by the user (for example, information input by an input method indicating the name of the data provider of the evidence to be stored).
And step 202, acquiring an original evidence corresponding to the evidence to be stored from the data provider indicated by the information.
In this embodiment, based on the evidence to be stored obtained in step 201 and the information indicating the data provider of the evidence to be stored, the executing entity may obtain the original evidence corresponding to the evidence to be stored from the data provider indicated by the information. The original evidence corresponding to the evidence to be stored can be data stored by the data provider and indicating the same event as the evidence to be stored. Here, the original evidence is the same as the event indicated by the evidence to be stored (e.g., both indicate that the a-blogger issued a microblog message at point 10), but the fact indicated by the two is not necessarily the same.
It can be understood that after the user acquires the evidence to be stored from the data provider, there is a possibility that the evidence to be stored is modified, at this time, the fact of the event may change, and of course, if the user does not modify the acquired evidence to be stored, the evidence to be stored may indicate the same fact as the original evidence.
Specifically, after determining a data provider of the evidence to be stored based on the received information, the executing entity may send a request for obtaining an original evidence of the evidence to be stored to the data provider, and then the data provider may extract the original evidence corresponding to the evidence to be stored from the database and send the extracted original evidence to the executing entity.
It should be noted that the data provider may extract, from the database, the original evidence corresponding to the evidence to be stored based on the characteristics of the evidence to be stored. The characteristics of the evidence to be stored can be sent to the data provider by the execution subject, or can be identified by the data provider from the evidence to be stored. Further, if the feature of the evidence to be stored is that the execution subject sends to the data provider, the feature of the evidence to be stored may be that the execution subject recognizes from the evidence to be stored, or may be that the user uses the user side to send to the execution subject. Here, the characteristics of the evidence to be stored may include various characteristics, and the characteristics of the evidence to be stored may include, for example, a generation time of the evidence to be stored, a related person (e.g., a blogger) of the evidence to be stored, a keyword for indicating the content of the evidence to be stored, and the like.
In step 203, a block is generated based on the evidence to be stored and the evidence in the original evidence.
In this embodiment, the execution subject may generate a block based on the to-be-stored evidence obtained in step 201 and the evidence in the original evidence obtained in step 202.
Specifically, the execution subject may generate a block based on the evidence to be stored, may generate a block based on the original evidence, or may generate a block based on the evidence to be stored and the original evidence.
The block is a basic constituent unit of the block chain, and in practice, an encryption algorithm (e.g., a hash algorithm) may be used to pack information to be stored in the block chain, so as to obtain the block. In this embodiment, the execution subject may generate the block in various ways based on the evidence in the to-be-stored evidence and the original evidence. As an example, the execution subject may directly pack the evidence to be stored and the evidence in the original evidence to obtain a block; alternatively, an evidence digest indicating the main content of the evidence (i.e., the evidence to be stored and the evidence used for generating the block in the original evidence) may be extracted, and then the evidence digest is packaged to obtain the block. It can be understood that compared with the direct packed evidence, the packed evidence abstract can reduce the data volume of the packed data, thereby being beneficial to improving the efficiency of block generation and reducing the consumption of block chain storage resources.
In some optional implementations of the embodiment, the execution subject may generate the block based on one of the to-be-stored evidence and the original evidence in response to the to-be-stored evidence matching the original evidence. Specifically, the execution subject may generate a block based on the evidence to be stored, or may also generate a block based on the original evidence. It should be noted that, here, the matching of the evidence to be stored and the original evidence may refer to the fact that the two evidence indications are the same. It can be understood that when the evidence to be stored and the fact indicated by the original evidence are the same (i.e. the evidence to be stored matches the original evidence), only one evidence is stored to store the data for proving the fact, so that the data amount of the stored data can be reduced while the validity of evidence storage is ensured, and the generation efficiency of the block can be improved.
In some optional implementations of the embodiment, the execution subject may generate the block based on the to-be-stored evidence and the original evidence in response to the to-be-stored evidence not matching the original evidence. It can be understood that when the evidence to be stored is different from the fact indicated by the original evidence (that is, the evidence to be stored is not matched with the original evidence), it can be stated that the evidence to be stored provided by the user is not a real evidence, and the user may have a behavior of modifying the evidence, and at this time, storing the evidence to be stored and the original evidence simultaneously can store the behavior data of the evidence modified by the user while storing data for proving a certain fact, so that the comprehensiveness of data storage is improved; and the user can store the behavior data of the modified evidence when modifying the evidence, so that the behavior data can reversely act on the user and the possibility of modifying the evidence by the user is reduced.
In step 204, the block is added to the target block chain.
In this embodiment, based on the block obtained in step 203, the execution body may add the block to the target block chain. The target block chain is a block chain to which the execution main body belongs. The execution subject is a node of the target block chain, and may acquire information of the target block chain (for example, a hash value of a block currently located at the end of the target block chain), and may further add a block to the target block chain.
In this embodiment, the executing entity may obtain the related information of the block generated in step 203, and store the related information and the evidence used for generating the block to a target evidence management end (e.g., the evidence management end 105 shown in fig. 1). The related information of the block may include various information related to the generated block, for example, the generation time of the block, the number of the block in the target block chain, the time when the block is added to the target block chain, and the like. The target evidence management terminal may be configured to manage the evidence sent by the execution principal.
Specifically, the executing entity may send the relevant information and the evidence used for generating the block in step 203 to the target evidence management terminal, so that the target evidence management terminal stores the received relevant information and the evidence.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the method for processing information according to the present embodiment. In the application scenario of fig. 3, the evidence storing device 301 may obtain the evidence to be stored 304 sent by the user terminal 302 and information 305 indicating the data provider of the evidence to be stored 304 in response to receiving the evidence storage request 303 sent by the user terminal 302. Then, the evidence storing device 301 may obtain the original evidence 307 corresponding to the evidence 304 to be stored from the data provider 306 indicated by the information 305. Then, the vouching device 301 may generate a block 308 based on the evidence 304 to be stored and evidence in the original evidence 307 (e.g., generate block 308 based on the original evidence 307). The vouching device 301 may then add the block 308 to the target block chain 309. Finally, the evidence storage device 301 may obtain the related information 310 of the block 308 and store the related information 310 and the evidence (e.g., the original evidence 307) used to generate the block 308 to the target evidence management terminal 311.
According to the method provided by the embodiment of the disclosure, when the evidence which the user side requests to store is stored, the evidence is firstly stored in the target block chain, so that the possibility that the evidence is tampered can be reduced; in addition, the original evidence corresponding to the evidence to be stored acquired from the data provider can be used for verifying the evidence to be stored provided by the user side, so that the authenticity of the stored evidence can be improved.
With further reference to FIG. 4, a flow 400 of yet another embodiment of a method for processing information is shown. The flow 400 of the method for processing information includes the steps of:
In this embodiment, an executing entity (e.g., the evidence storing device 104 shown in fig. 1) of the method for processing information may obtain the evidence to be stored sent by the user terminal and information indicating a data provider (e.g., the data provider 106 shown in fig. 1) to which the evidence to be stored is to be stored, in response to receiving an evidence storage request sent by the user terminal (e.g., the user terminals 101, 102, 103 shown in fig. 1) through a wired connection manner or a wireless connection manner. The user side is a terminal used by a user. The evidence storage request is used for requesting storage of the evidence acquired by the user. The evidence to be stored is the evidence which is acquired by the user and is to be stored. Evidence is data that is used to prove some fact.
It should be noted that, here, the evidence to be stored may be electronic evidence that can be transmitted in electronic communication.
And 402, acquiring original evidence corresponding to the evidence to be stored from the data provider indicated by the information.
In this embodiment, based on the evidence to be stored obtained in step 401 and the information indicating the data provider of the evidence to be stored, the execution subject may obtain the original evidence corresponding to the evidence to be stored from the data provider indicated by the information. The original evidence corresponding to the evidence to be stored can be data stored by the data provider and indicating the same event as the evidence to be stored.
In step 403, a block is generated based on the evidence to be stored and the evidence in the original evidence.
In this embodiment, the execution subject may generate the block based on the to-be-stored evidence obtained in step 401 and the evidence in the original evidence obtained in step 402.
At step 404, the block is added to the target block chain.
In this embodiment, based on the block obtained in step 403, the execution body may add the block to the target block chain. The target block chain is a block chain to which the execution main body belongs.
In this embodiment, the execution agent may obtain the related information of the block generated in step 403, and store the related information and the evidence used for generating the block to a target evidence management end (e.g., the evidence management end 105 shown in fig. 1). The related information of the block may include various information related to the generated block. The target evidence management terminal may be configured to manage the evidence sent by the execution principal.
And step 406, acquiring the evidence mark fed back by the target evidence management terminal.
In this embodiment, after the relevant information and the evidence used for generating the block are stored in the target evidence management end, the execution subject may obtain an evidence mark fed back by the target evidence management end. Wherein the evidence flag is used to flag the stored evidence used to generate the block in step 403. In particular, the evidence indicia may be various indicia, such as a number of stored evidence.
In practice, when the target evidence management end stores the evidence, the target evidence management end may assign an evidence mark for uniquely characterizing the evidence to the stored evidence, and after step 405, the execution subject may obtain, from the target evidence management end, an evidence mark corresponding to the evidence for generating the block in step 403.
It should be noted that, here, the target evidence management end may perform associated storage on the relevant information of the block and the evidence used for generating the block, so that, when obtaining evidence, the target evidence management end may obtain the evidence stored in the target evidence management end based on the evidence mark and obtain the relevant information of the block generated by using the evidence, thereby on one hand, the comprehensiveness of information acquisition may be improved, and on the other hand, it may be further proved that the evidence has been stored in the target block chain, and the evidence is low in possibility of being tampered.
In this embodiment, based on the evidence mark obtained in step 406, the executing entity may send the evidence mark to the user side, so that the user may extract (i.e., obtain evidence) the evidence stored in the target evidence management side based on the evidence mark.
In some optional implementations of this embodiment, after sending the evidence mark to the user end, the executing entity may perform the following steps: firstly, in response to receiving an acquisition request for evidence marked by evidence marking, which is sent by a user terminal, the evidence marked by the evidence marking is acquired from a target evidence management terminal. And then, sending the acquired evidence marked by the evidence mark to the user terminal.
As can be seen from fig. 4, compared with the embodiment corresponding to fig. 2, the flow 400 of the method for processing information in this embodiment highlights steps of obtaining, after storing the evidence and the related information to the target management end, an evidence flag fed back by the target evidence management end for marking the stored evidence, and sending the evidence flag to the user end. Therefore, the scheme described in this embodiment can feed back the evidence mark of the stored evidence to the user side after the user side requests to store the evidence, which is helpful for the user side to acquire the stored evidence by using the evidence mark, and improves the comprehensiveness of information processing.
With further reference to fig. 5, as an implementation of the methods shown in the above figures, the present disclosure provides an embodiment of an apparatus for processing information, which corresponds to the method embodiment shown in fig. 2, and which is particularly applicable in various electronic devices.
