The embodiment is applicable to a scenario of protecting identity information of a data provider that uploads data in a blockchain, where the applicable blockchain may be a public chain, a private chain, or an alliance chain. Preferably, the block chain used in this embodiment is a federation chain. The method may be performed by a block chain based data uplink storage device, which may be comprised of hardware and/or software and may be integrated in an electronic apparatus, preferably an electronic apparatus with communication functionality
In the first embodiment, the first step is,
referring to fig. 1, a communication tracing method based on a block chain includes the following steps:
step S201: and acquiring a communication request, and acquiring a request object and a requested object according to the communication request.
It can be understood that the communication request is obtained from the communication information of the communication network, and the user terminal requesting communication and the user terminal requested to communicate are analyzed according to the communication request. Actually, when an enterprise needs to send a short message or dial communication to a user, a user number needing communication is input through an instant communication network, a communication request is sent, the user number is determined as a request object according to a dial end after the communication request is received, the user number is the enterprise, and a called number is the requested object.
In the specific communication embodiment, when an enterprise needs to send a promotion short message or a telephone to a user, the system server analyzes a calling number requesting communication, the calling number belongs to a specific enterprise, and determines whether the enterprise is on record. And analyzing the number of the user which needs to be called by the enterprise according to the request of the communication.
That is, the enterprise needs to register in advance as the called promotion number, and if the number which is not in the register can not be called, the system considers the harassment number to refuse to get through.
Step S202: judging whether the request object obtains the authorization of the requested object or not according to the request object and the requested object;
referring to fig. 3, further, the determining whether the request object is authorized by the request object is performed;
step S301: according to the requested object, the user authorization information of the requested object; and according to the request object, the request record information of the request object.
Step S302: comparing the user authorization information with the request record information to analyze whether the request object is authorized:
if not, sending a request rejection;
if yes, the instant messaging between the request object and the requested object is communicated.
It can be understood that after the request object sends out the request communication, the communication can be performed only after the authorization of the requested object is obtained; otherwise, the communication is rejected if the communication is considered to be harassing. Meanwhile, the request object must be a recorded request object, otherwise, the request object is regarded as an unauthorized request communication object, which disturbs the communication object and rejects the request communication thereof. And through the filing information of the request object, the dispute object can be rapidly determined in the later dispute complaints, and the harassment of the requested object can be effectively reduced.
In the specific embodiment, after the called enterprise number is acquired, whether the number is a record number of the enterprise is analyzed, and if not, the dialing request of the number is rejected; if the number is the registered number of the enterprise, the call is considered as a compliant call request, and communication can be successful after the called number is successfully authorized. Meanwhile, according to the called number, searching whether the authorization file of the number user to the calling enterprise exists or not, and if not, refusing the communication; if yes, communication is allowed, namely the enterprise calls the number user to be called successfully.
Further, the user authorization information of the requested object is an authorization file formed after the user passes authorization.
In the embodiment, the user obtains the authorization file after authorizing a certain authorization file in the same way of a user side, a page or a paper contract. The user authorization information can be changed on the user side by the user. If initially, the authorized enterprise sends a communication to the user, and the user dislikes the enterprise in step S203: and acquiring communication data of instant messaging, and generating encrypted data through encryption.
Further, the generating of the encrypted data by encryption is encrypting the information of the requested object by cryptography;
and the information of the request object is encrypted and managed by the KMS.
The information of the request object is encrypted and managed through the KMS, namely, each request object is distributed with a private key.
Further, the communication data is backup data of a communication data source file;
the communication data includes one or more of the following information: text information, audio information, and video information.
Specifically, the encrypted data of the instant messaging message is written into the block chain after being subjected to hash processing. Because the data after the hash processing is smaller, compared with the encrypted data which is directly stored even if the communication message is stored, the hash value of the message data is stored on the chain, so that the occupation of the storage space on the chain is reduced, the data on the chain is prevented from being overstaffed, and the processing efficiency is improved; meanwhile, the nodes in the blockchain can verify whether the hash value changes according to the hash algorithm to verify whether the message data is tampered, so that the verification efficiency is improved.
Step S204: and writing the encrypted data into a block chain for storage.
In the embodiment, decentralized distributed storage of the instant messaging message is realized by using the block chain, and the instant messaging message is stored by using the ciphertext, so that the situations that the communication information is stolen, tampered, deleted and maliciously attacked can be effectively avoided, and the communication privacy security of the user can be better ensured. The problem that the communication privacy of a user is unsafe due to the fact that information of an existing traditional instant communication platform is tampered, deleted and maliciously attacked is solved.
Example two
Referring to fig. 2, a communication tracing method based on a block chain includes the following steps:
step S201: and acquiring a communication request, and acquiring a request object and a requested object according to the communication request.
It can be understood that the communication request is obtained from the communication information of the communication network, and the user terminal requesting communication and the user terminal requested to communicate are analyzed according to the communication request. Actually, when an enterprise needs to send a short message or dial communication to a user, a user number needing communication is input through an instant communication network, a communication request is sent, the user number is determined as a request object according to a dial end after the communication request is received, the user number is the enterprise, and a called number is the requested object.
In the specific communication embodiment, when an enterprise needs to send a promotion short message or a telephone to a user, the system server analyzes a calling number requesting communication, the calling number belongs to a specific enterprise, and determines whether the enterprise is on record. And analyzing the number of the user which needs to be called by the enterprise according to the request of the communication.
Step S202: judging whether the request object obtains the authorization of the requested object or not according to the request object and the requested object;
referring to fig. 3, further, the determining whether the request object is authorized by the request object is performed;
step S301: according to the requested object, the user authorization information of the requested object; and according to the request object, request record information of the request object.
Step S302: comparing the user authorization information with the request record information to analyze whether the request object is authorized:
if not, sending a request rejection;
if yes, the instant messaging between the request object and the requested object is communicated.
It can be understood that after the request object sends out the request communication, the communication can be performed only after the authorization of the requested object is obtained; otherwise, the communication is rejected if the communication is considered to be harassing. Meanwhile, the request object must be a recorded request object, otherwise, the request object is regarded as an unauthorized request communication object, harasses the communication object and rejects the request communication of the communication object. And through the filing information of the request object, the dispute object can be rapidly determined in the later dispute complaints, and the harassment of the requested object can be effectively reduced.
In the specific embodiment, after the called enterprise number is acquired, whether the number is a record number of the enterprise is analyzed, and if not, the dialing request of the number is rejected; if the number is the record number of the enterprise, the calling is considered as a compliant calling request, and the communication can be successful after the called number is successfully authorized. Meanwhile, searching according to the called number, judging whether the user of the number has an authorization file for calling the enterprise, and if not, refusing communication; if yes, communication is allowed, namely the enterprise calls the number user to be called successfully.
Further, the user authorization information of the requested object is an authorization file formed after the user passes authorization.
In the embodiment, the user obtains the authorization file after authorizing a certain authorization file in the same way of a user side, a page or a paper contract. The user authorization information can be changed on the user side by the user. If initially, the authorized enterprise sends a communication to the user, and the user dislikes the enterprise in step S203: and acquiring communication data of instant messaging, and generating encrypted data through encryption.
Further, the generating of the encrypted data by encryption is encrypting the information of the requested object by cryptography;
and the information of the request object is encrypted and managed through the KMS.
The information of the request object is encrypted and managed through the KMS, namely, each request object is distributed with a private key.
Further, the communication data is backup data of a communication data source file;
the communication data includes one or more of the following information: text information, audio information, and video information.
Specifically, the encrypted data of the instant messaging message is written into the block chain after being subjected to hash processing. Because the data after the hash processing is smaller, compared with the encrypted data which is directly stored even if the communication message is stored, the hash value of the message data is stored on the chain, so that the occupation of the storage space on the chain is reduced, the data on the chain is prevented from being overstaffed, and the processing efficiency is improved; meanwhile, the nodes in the blockchain can verify whether the hash value changes according to the hash algorithm to verify whether the message data is tampered, so that the verification efficiency is improved.
Step S204: and writing the encrypted data into a block chain for storage.
In the embodiment, decentralized distributed storage of the instant messaging message is realized by using the block chain, and the instant messaging message is stored by using the ciphertext, so that the situations that the communication information is stolen, tampered, deleted and maliciously attacked can be effectively avoided, and the communication privacy security of the user can be better ensured. The problem that the communication privacy of a user is unsafe due to the fact that information is tampered, deleted and maliciously attacked in the conventional instant communication platform is solved.
Step S205: referring to fig. 4, the step of retrieving the encrypted data written into the block chain for storage includes:
step S401: acquiring a calling instruction, wherein the calling instruction comprises called object information, calling object information and authority information;
step S402: analyzing whether the calling instruction has the authority, and if so, calling by giving; otherwise, the data is not passed;
step S403: acquiring a corresponding private key according to the calling object information of the calling instruction;
step S404: and acquiring the calling communication data according to the private key and the called object information.
It can be understood that the related communication records need to be called, and the calling needs to be performed by a management department with management authority, otherwise, the calling is rejected. Meanwhile, when the corresponding communication data related to the enterprise is called, the private key of the enterprise is obtained only by obtaining the authorization of the enterprise, and the private key is stored for the enterprise. That is, after the management authority of the calling is passed, the communication data needing to be called is determined according to the private key of the calling object and the information of the called object, and the communication data set is called and is referred by a manager.
In the specific embodiment, when a dispute occurs, such as a harassment complaint of a user is received, a management department with management authority operates to call the complaint item of the complaint user. Specifically, the query client accesses the data deposit system through an HTTPS (hypertext transfer protocol secure) WEB browser, and simultaneously sends a request for querying the deposit information to the data deposit system, and the data deposit system requests the query to provide the private key of the complaint enterprise after receiving the request for querying the deposit information. The management department provides a private key which is required to be provided by the complaint enterprise in advance, and the system inquires according to the enterprise corresponding to the private key and the number of the complaint user, so that the corresponding communication record is searched for the management department to look up, and a correct processing result is made for the complaint.
According to the embodiment, an enterprise merchant is supported to flexibly and conveniently inquire and obtain user authorization based on the user authorization voucher information chaining by taking a customer as a center and taking actual service as scene driving through a block chain trusted service and communication service scene, and the traceability of communication service is quickly met.
