Description
Technical Field
The invention belongs to the technical field of mobile communication, and particularly relates to a blacklist number sharing and identification method, device, equipment and storage medium.
Background
With the rapid development of the mobile internet, the harassment problems of the telephone, the short message and the like of the mobile terminal become more serious, on one hand, the harassment problems not only influence the work and the life of the user, but also possibly damage the economic benefit of the user; on the other hand, the harassment problems seriously affect the use experience of users, and also affect the image and reputation of the system parties such as terminal manufacturers and operators.
Aiming at various existing harassment problems, most users can solve the harassment problems of calls, short messages and the like by using blacklist number identification software preinstalled on a mobile terminal or blacklist number identification software of a third party.
Although this approach can solve the disturbance problem to some extent, there are some problems as follows:
firstly, databases of the identification software are not communicated with each other (cannot be shared with each other), so that the requirement of user for preventing harassment cannot be met to the maximum extent unless the user installs a plurality of identification software on the mobile terminal at the same time. However, the way of installing multiple pieces of identification software on the mobile terminal at the same time is inconvenient, and because the identification capabilities of the multiple pieces of identification software are different, different identification results may occur for the same number, so that the user cannot make a judgment according to the different identification results.
Secondly, currently, each blacklist number reporting function of the identification software is generally provided with a reporting time threshold, and when the reporting time of a number exceeds the reporting time threshold, the number is brought into a blacklist number library so as to prompt and intercept the number. Because different identification software used by different users is different, the numbers reported by the users cannot be synchronized to the databases of all the identification software in time, and further, the reported numbers are not included or are included in a delayed manner (the time reaching the reporting time threshold is delayed), so that inconvenience is brought to the users.
Thirdly, when the user uses the recognition software to report the blacklist number, the possibility of malicious reporting exists, and therefore unnecessary troubles and damage to the reputation are caused to the user.

In order to solve the problem of the prior art, embodiments of the present invention provide a method, an apparatus, a device, and a storage medium for sharing and identifying a blacklist number.
First, a blacklist number verification system applied in the embodiment of the present invention is described below.
The blacklist number verification system applied by the embodiment of the invention comprises a plurality of mobile terminals, a reporting node, a verification node and a query node.
The mobile terminal is provided with blacklist number identification software, and the blacklist number identification software can be blacklist number identification software pre-installed on the mobile terminal, and also can be blacklist number identification software of a third party installed on the mobile terminal, such as safety guard software of 360 mobile phone guards, Tencent mobile phone stewards and the like. The user can report and inquire the blacklist number through the blacklist number identification software on the mobile terminal. The reporting node of the mobile terminal may communicate with the query node and the reporting node, respectively.
The reporting node can be any data server of the blacklist number identification software background, and the reporting node can receive a reporting verification request sent by a user through the blacklist number identification software on the mobile terminal and forwards the reporting verification request to the verification node for verification.
The verification node can be a cloud server and is used for being in butt joint with the reporting node, receiving a reporting verification request sent by the reporting node, and verifying the information of a reporter and the reported blacklist number so as to generate a new block of the block chain.
The cloud server can also be provided with a feature cluster for storing blacklist numbers and number features thereof.
The query node can be the same node as the reporting node or different nodes, and the query node can also be any data server of the background of the blacklist number identification software. The inquiry node is used for acquiring the unknown number as a number to be identified when the mobile terminal receives a call of the unknown number, and inquiring whether the number to be identified is a blacklist number or not in the feature cluster so as to prompt a user through the mobile terminal.
The blacklist number sharing and identifying method, device, equipment and storage medium provided by the embodiment of the invention are applied to the blacklist number verification system.
Fig. 1 is a flowchart illustrating a blacklist number sharing method according to an embodiment of the present invention. As shown in fig. 1, the blacklist number sharing method is applied to a verification node of a blacklist number verification system, and the method includes:
s110, acquiring a report verification request; the reporting verification request comprises reporting person information, reported blacklist numbers and number characteristics of the blacklist numbers;
s120, verifying the information of the reporter, writing the information of the reporter and the blacklist number into a block by using a common identification mechanism if the information of the reporter passes the verification, and storing the number characteristics of the blacklist number into a characteristic cluster;
s130, generating a report preparation request according to the blacklist number and the platform identification of the verification node;
s140, broadcasting the report preparation request to other verification nodes, and if the report preparation request passes the verification of other verification nodes, writing the blacklist number and the platform identifier into a block by using a common identification mechanism so as to share the blacklist number to a blacklist number library.
Therefore, the embodiment of the invention can utilize the block chain technology to verify the information of the reporter after acquiring the report verification request, write the information of the reporter and the blacklist number into the block if the information of the reporter passes the verification, and store the number characteristics of the blacklist number into the characteristic cluster, and if the information of the reporter passes the verification, a report preparation request can be generated and broadcasted, if the report preparation request passes the verification of other verification nodes, the blacklist number and the platform identification are written into the block, so as to share the blacklist number to the blacklist number library, therefore, the reported blacklist number can be quickly shared to the blacklist number library, meanwhile, the block chain has the advantage of being incapable of being tampered, so that the data security of the blacklist number library can be ensured, and in addition, since the reporter information for reporting the blacklist number is registered, malicious reporting of the reporter can be prevented.
In embodiments of the present invention, the block header of the block uses current general techniques, and the block address may be included in the block header. The block body of the block comprises a report information part and a verification information part, wherein the report information part and the verification information part are respectively composed of a plurality of records, the report information part is used for storing the information of a report person and the number of a blacklist, and the verification information part is used for storing the number of the blacklist and the identification of a platform.
Fig. 2 is a flowchart illustrating a method for writing information into a block according to an embodiment of the present invention. As shown in fig. 2, in step S120 and step S130, a specific method for writing the information about the reporter and the blacklist number into the block may include:
s210, converting the information of the newspaper raiser and the blacklist number into corresponding hash values respectively;
s220, writing the hash value corresponding to the reporter information and the hash value corresponding to the blacklist number into a block.
Specifically, in the embodiment of the present invention, each record of the report information part includes a hash value of the report information (such as a mobile phone number, a mailbox address, an identification number, and the like of the report) and a hash value of the blacklist number. If the person reporting information is identified by PersonHash, the blacklist number is identified by NumberHash, and the hash function is represented by H, each record of the information reporting part is stored as follows:
personHash H (Phonenumber [ mobile phone number ], E-mail address [ email address ], …)
Number hash H (ReportNumber ])
In the embodiment of the present invention, each record of the verification information portion contains information that the blacklist number is verified by the verification node, for example, a certain number is verified as a blacklist number by the verification node corresponding to a certain verification platform, and then the number and a platform identifier (for example, a platform name) of the corresponding verification platform can be recorded in the blockchain, and the form is as follows:
number hash: platform identification
According to the above manner, after the blacklist number, the reporter information, and the platform identifier are written into the block, the block body shown in fig. 3 can be formed.
Fig. 4 shows a schematic diagram of the structure of a feature cluster according to an embodiment of the present invention. Fig. 5 shows a schematic structural diagram of a feature cell of one embodiment of the present invention.
As shown in fig. 4, a feature cluster, that is, a feature set of a blacklist number according to an embodiment of the present invention, includes a plurality of feature units, and each feature unit corresponds to a feature of the blacklist number. The feature units in the feature cluster dynamically change with the increase and development of the blacklist number. As shown in fig. 5, each feature unit stores a blacklist number having the feature and a block address of a block stored in the blacklist number.
Generally, the blacklist numbers described in the embodiments of the present invention refer to crank call numbers, and the following lists several main characteristics of the blacklist numbers:
1. number segment characteristics: the number with these number segments has a high probability of being a blacklisted phone, such as a number with a beginning of 400, 800, 95, "+" or "000".
2. The incoming call characteristic: hang up "make a sound".
3. Caller identification feature: displaying the unknown number and the number attribution.
4. The incoming call content characteristics are as follows: advertising promotion, fraud calls, real estate agents, financial products, and the like.
In step S120 of the embodiment of the present invention, a specific method for storing number features of a blacklist number to a feature cluster may include:
and storing the blacklist number and the block address corresponding to the written block into at least one corresponding feature unit in the feature cluster according to the number feature of the blacklist number. The blacklist number may also be converted into a hash value of the blacklist number and then stored.
Therefore, as shown in fig. 6, each feature unit may be associated with at least one block according to the blacklist number stored therein and the block address of the block in which the blacklist number is stored, and each block may also be associated with at least one feature unit because a plurality of blacklist numbers are stored in each block.
According to the blacklist number sharing method provided by the embodiment of the invention, when a mobile terminal of a user receives a crank call, the specific process of reporting the blacklist number by the user through the mobile terminal is as follows:
after receiving a crank call, a user can initiate a report verification request to a corresponding report node by using blacklist number identification software installed on a mobile terminal. The report verification request comprises report person information, reported blacklist numbers and number characteristics of the blacklist numbers.
And the reporting verification request received by the reporting node is sent to the verification node, and the reporting node broadcasts and initiates the reporting verification request to the block chain system. After any verification node in the block chain system receives the report verification request, the reporter is verified according to the reporter information submitted by the reporter contained in the request (for example, the mobile phone number can be verified in a short message verification code mode and the like), and the verification node only reserves the successfully verified reporter information and the reported blacklist number, including the hashed value of the reporter information and the hashed value of the blacklist number. The verification node writes the hash value of the reporter information and the hash value of the blacklist number into the report information part in the corresponding block by using a common identification mechanism, and simultaneously stores the hash value of the blacklist number and the block address corresponding to the written block into different feature units of the feature cluster according to the number features of the blacklist number. And when the reported blacklist number passes the verification of a certain verification node, reporting can be carried out. And after the verification node initiates a report preparation request, broadcasting the report preparation request in the block chain system. The reported blacklist number and the hash value thereof, the platform identification of the verification node and the number characteristic that the reported blacklist number passes the verification of the verification node are contained in the reported report preparation request. After other verification nodes in the block chain receive the report preparation request, verifying the correctness of the information in the report preparation request, including calculating the hash value of the reported blacklist number in the report preparation request, and verifying whether the calculated hash value is consistent with the hash value in the report preparation request. If not, discarding the report preparation request, and ending the verification process; and if the two blocks are consistent, writing the hash value of the blacklist number and the platform identification of the verification node into the verification information part in the corresponding block by using a common identification mechanism.
In summary, the verification node according to the embodiment of the present invention can determine whether the reported blacklist number is a harassing call by using a common identification mechanism, so that the problem of malicious reporting can be avoided. Meanwhile, the block chain stores the information of the reporter and can trace the reporter, so that the problem of malicious reporting is further avoided. In addition, the embodiment of the invention utilizes each verification node to ensure the correctness and the safety of the information in the block chain together, namely the blacklist number and the corresponding information which are already recorded in the block chain cannot be tampered, and the non-blacklist number and the corresponding information cannot be recorded in the block chain, thereby ensuring the correctness of the information and the safety of the information in the block chain.
It should be noted that, although the embodiment of the present invention describes a method for sharing blacklist numbers by taking an incoming blacklist number as an example, the embodiment of the present invention is also applicable to reporting and sharing blacklist numbers when a blacklist number sends a short message to a mobile terminal.
Fig. 7 is a flowchart illustrating a blacklist number identification method according to an embodiment of the present invention. As shown in fig. 7, the blacklist number identification method is applied to a query node of a blacklist number verification system, and the method includes:
s310, acquiring a number to be identified;
s320, inquiring whether the number to be identified is stored in the feature cluster as a blacklist number;
s330, if the number to be identified is stored in the feature cluster as the blacklist number, inquiring a block corresponding to the blacklist number to determine a verification node corresponding to the blacklist number.
The embodiment of the invention can directly send the incoming call number as the number to be identified to the query node through the blacklist number identification software of the mobile terminal when the mobile terminal receives the incoming call of the unknown number, and query in the feature cluster, and query the corresponding verification node when the number to be identified is the blacklist number, so that the prompt or interception that the unknown number is the blacklist number can be received before the user answers the call, and the user is prompted to verify the verification platform corresponding to the verification node of the blacklist number. Because the embodiment of the invention can store the blacklist number and the corresponding number characteristic by using the characteristic cluster, the inquiry of the blacklist number and the update of the number characteristic can be quickly carried out by using the characteristic cluster, thereby solving the problems that the speed of inquiring the blacklist number and the number characteristic thereof by using a block chain is slow and the number characteristic thereof can not be changed.
Fig. 8 is a flowchart illustrating a method for querying a number to be identified in a feature cluster according to an embodiment of the present invention. As shown in fig. 8, the specific method for querying whether the number to be identified is stored in the feature cluster as a blacklist number in step S320 may include:
s321, calculating a hash value corresponding to the number to be identified;
s322, inquiring whether the number to be identified is stored as a blacklist number in the feature cluster according to the hash value corresponding to the number to be identified.
Specifically, the hash value corresponding to the number to be identified may be used as a key value, and the feature cluster is searched for whether a corresponding hash value exists in each feature unit of the feature cluster, and if so, it is determined that the number to be identified is stored in the feature cluster as a blacklist number, where the number to be identified is the blacklist number; and if not, determining that the number to be identified is not stored in the feature cluster as a blacklist number, wherein the number to be identified is not determined to be the blacklist number.
Fig. 9 is a flowchart illustrating a blacklist number identification method according to another embodiment of the present invention. As shown in fig. 9, the method for identifying a blacklist number further includes:
s340, if the number to be identified is not inquired and is stored in the feature cluster as the blacklist number, acquiring a plurality of number features corresponding to the number to be identified;
and S350, determining the probability that the number to be identified is the blacklist number according to the number characteristics.
In the embodiment of the invention, when only a few users report the blacklist number, the blacklist number verification system does not reach consensus, namely a new block is not established, and at the moment, whether the number to be identified is the blacklist number cannot be directly inquired.
In the embodiment of the invention, if the number to be identified is not inquired and stored in the feature cluster as the blacklist number, the user is not prompted in advance. After the user answers the call of the blacklist number, if the call is suspected to be a harassing call, the probability that the number to be identified is the blacklist number can be further determined according to the number characteristics of the number to be identified.
Fig. 10 is a flowchart illustrating a method for determining a probability that a number to be identified is a blacklist number according to an embodiment of the present invention. As shown in fig. 10, in step S350, a specific method for determining a probability that a number to be identified is a blacklist number according to a plurality of number features may include:
s351, determining the total number of numbers in the feature cluster and the number corresponding to each feature unit in the feature cluster;
s352, calculating the weight corresponding to each feature unit according to the total number and the number of the numbers;
and S353, summing the weights corresponding to the feature units corresponding to the number features, and determining the probability that the number to be identified is the blacklist number.
In the embodiment of the invention, a user can send the number to be identified and the corresponding number characteristics to the query node through the blacklist number identification software of the mobile terminal, and the probability that the number to be identified is suspected to be the blacklist number can be estimated according to the number characteristics and the corresponding characteristics in the characteristic cluster.
Assuming that the probability that a certain number to be identified is suspected to be a blacklist number is represented as P, corresponding features in a feature cluster are represented as (T1, T2, T3, T4, …, T (n)), the numbers of blacklists having features of T1 and T2 … T (n) are respectively summed up to represent the number corresponding to each feature unit as (Q1, Q2, Q3, Q4, …, Qn), and the total number S of blacklist numbers in the feature cluster is calculated, wherein the weight of each feature in calculating the probability P is represented as (W1, W2, W3, W4, …, Wn), the following formula can be obtained:
wi ═ Qi/S (values of i are 1,2,3, …, n)
Through the formula, the probability that a certain number to be identified is a blacklist number can be predicted, and therefore better anti-harassment experience is provided for users.
Therefore, according to the method for identifying the blacklist number of the embodiment of the invention, when the mobile terminal of the user receives an incoming call of an unknown number, the incoming call number is taken as the number to be identified, and the specific process of identifying whether the incoming call number is the blacklist number is as follows:
when the mobile terminal receives an incoming call of an unknown number, the blacklist number identification software automatically sends the incoming call number as a number to be identified to the query node, the query node calculates the hash value of the number to be identified, and queries in the feature cluster by taking the hash value of the number to be identified as a key value.
If the hash value identical to the hash value of the number to be identified exists in the feature cluster, the block address of the block where the blacklist number corresponding to the hash value is located is directly inquired, information such as verification nodes which pass the blacklist number can be quickly inquired in the corresponding block according to the inquired block address, and therefore prompting or intercepting is conducted on a user according to the inquired information. When the inquired information is used for prompting the user, the user can directly add the incoming call number into the blacklist of the mobile terminal, namely refusing to receive the incoming call of the blacklist number. In addition, if the number characteristics of the blacklist number provided by the inquired reporter are not consistent with the number characteristics of the incoming call number, the number characteristics of the blacklist number can be updated in the number cluster by using blacklist number identification software.
If the hash value identical to the hash value of the number to be identified does not exist in the feature cluster, the incoming call number cannot be directly determined to be the blacklist number, the probability that the incoming call number is the blacklist number can be calculated through the number feature of the incoming call number provided by the user, and an early warning prompt is given, for example, the suspected rate that the xxxx number is the blacklist phone is 65%, so that better anti-harassment experience is provided for the user, and the capability of predicting and prompting a certain number before the number is not determined to be the blacklist number is solved.
