Detailed Description

For a better understanding of the embodiments of the present application, the following terms are now explained:

the block chain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. The consensus mechanism is a digital algorithm for establishing trust and obtaining rights and interests among different nodes in the blockchain system. The blockchain is an important concept of virtual currency, is essentially a decentralized database and is used as the underlying technology of the virtual currency. The block chain is a series of data blocks which are associated by using a cryptographic method, and each data block contains information of one bitcoin network transaction, so that the validity (anti-counterfeiting) of the information is verified and a next block is generated.

Decentralization is a social relationship form and a content generation form formed in the internet development process, and is a novel network content production process relative to centralization. In a system having a plurality of nodes distributed throughout, each node has a highly autonomous character. The nodes can be freely connected with each other to form a new connection unit. Any node can become a phased hub, but does not have mandatory hub control functions. The influence between nodes can form a nonlinear causal relationship through the network. This open, flattened, equal system phenomenon or structure is called decentralization.

Ethereum is an open-source, common blockchain platform with intelligent contract functionality, which provides an decentralized Virtual Machine (ethernet Virtual Machine) to handle point-to-point contracts through its private cryptocurrency etherman.

EOS (Enterprise Operation System, provided by a commercial distributed blockchain operating System) is a new blockchain architecture, and aims to implement performance expansion of distributed applications.

An intelligent contract is a computer protocol intended to propagate, validate or execute contracts in an informational manner. Smart contracts allow trusted transactions to be conducted without third parties, which transactions are traceable and irreversible. All users on the blockchain can see the intelligent contracts based on the blockchain.

In the related art, the marking means of the harassing calls is generally limited by the following aspects:

firstly, limited by smart phone manufacturers, different mobile phone manufacturers can adopt different incoming call anti-harassment schemes, and no matter local storage or cloud service storage is adopted, the data can be stored in own data of the manufacturers, the mobile phones of the manufacturers are only supported to use, and users cannot use original data after replacing the mobile phones of different manufacturers.

Secondly, limited by a third-party yellow page service company, the yellow page service company can maintain relevant data based on the marks of the users, and a mobile phone manufacturer integrates the data to acquire the capability of identifying the incoming call. However, this kind of marking method has the same problem as the first aspect, and different mobile phone manufacturers may choose to integrate different yellow page contents, so that the user cannot use the original data after replacing the mobile phones of different manufacturers.

And thirdly, the data can be usually stored in the cloud by marking through the application program, and a user can log in through a mobile phone number, so that the user can use the original data even if the user changes the mobile phone. However, the disadvantage of using the application program is that the marked data is completely controlled by the operator of the application program, and although the harassing calls marked by the users can be uploaded to the cloud, other users may acquire the data only if the number of the marks reaches a certain degree. And the method has the delay of data sharing and can be even tampered by operators. In addition, data of different application programs cannot be shared, and efficient and accurate identification cannot be achieved.

The following is illustrated with reference to the examples:

the embodiment of the application provides a method for preventing harassing calls, the method is used in a terminal, the terminal can be a computer or a mobile intelligent device, the computer or the mobile intelligent device can identify harassing call numbers by using a block chain technology when executing the method, and the method is not influenced by changing a telephone, changing numbers or changing operators, the functions realized by the method can be realized by calling program codes through a processor in the terminal, of course, the program codes can be stored in a storage medium readable by the computer, and the terminal at least comprises the processor and the storage medium.

Fig. 1 is a schematic flow chart of an implementation process of a method for preventing a harassing call according to an embodiment of the present application, and as shown in fig. 1, the method includes:

step S101, when a terminal receives a strange call, acquiring an address of a node where a data set on a block chain is located;

in practical application, the data set may be an intelligent contract in a block chain, and the terminal acquires an address of the intelligent contract so as to implement marking of a harassing call by the intelligent contract subsequently. In this embodiment, when a terminal receives an unfamiliar incoming call, whether the unfamiliar incoming call is a harassing call is judged through a blockchain, and actually, under the condition that the unfamiliar incoming call is not received, the marking information of the harassing call recorded in an intelligent contract can be obtained through the intelligent contract in the blockchain and downloaded to the local; when an unfamiliar incoming call is received, whether the incoming call number is a crank call can be known by searching the local record.

Step S102, acquiring mark information in the data set according to the address of the node where the data set is located;

the terminal acquires the mark information recorded in the intelligent contract according to the intelligent contract address in the block chain. The tagging information here is used to tag telephone numbers that have been identified as nuisance calls. The tag information comprises a telephone number, when the terminal receives an unfamiliar call, the telephone number of the unfamiliar call is found in the tag information, and the telephone number is considered as a crank call. Other characteristic attributes related to the telephone number, such as region, type, etc., may also be included in the tagging information, and the time of tagging, the number of times of tagging, etc. may also be included in the tagging information. The information can be provided to the terminal by the intelligent contract, and when the terminal receives an unfamiliar call, the user can determine whether to answer the call by marking the content in the information.

And step S103, when the mark information comprises the telephone number of the unfamiliar incoming call, marking the telephone number as a crank call.

The tag information may include various telephone numbers that have been marked as harassing calls, when the terminal receives an unfamiliar incoming call, the telephone number of the unfamiliar incoming call may be searched for in the tag information, and when the telephone number can be found in the tag information, it is described that the telephone number has been marked as a harassing call, and at this time, the terminal marks the telephone number as a harassing call, and the terminal may also perform corresponding operations on the telephone number. For example, the number is directly displayed as a crank call on a display interface during incoming call to remind the user; it can also be set to directly reject automatically or mask automatically an incoming call, etc. And when the telephone number of the strange incoming call cannot be found in the marking information, the telephone number is not marked as a harassing call, and at the moment, the terminal can not perform operations such as reminding and the like.

In other embodiments, the tag information includes a phone number and a tag time; the acquiring the mark information in the data set according to the address of the node where the data set is located includes:

step S102a, downloading a mark list in the data set according to the address of the node where the data set is located; wherein the tag list includes at least one item of the tag information;

step S102b, obtaining the label information from the label list.

The intelligent contract in the block chain records all the marked information marked with the crank call in the mark list, and the terminal downloads the mark list first and acquires the mark information through the mark list. The tag information here includes a telephone number and a tag time, and since the telephone number recorded in the tag information is a telephone number tagged as a nuisance call, it is possible to record only the tagged telephone number without recording other information, or to record other related information such as the tag time.

In practical application, the terminal can download the mark list in the intelligent contract periodically, and can also download the mark list in the intelligent contract when an unfamiliar call is received. After the terminal downloads the mark list, the downloaded data or repeated data can be deleted, so that the memory space is saved.

An embodiment of the present application provides another method for preventing a harassing call, as shown in fig. 2, where the method includes:

step S201, when a terminal receives a strange call, acquiring an address of a node where a data set on a block chain is located;

step S202, the terminal acquires mark information in the data set according to the address of the node where the data set is located;

step S203, when the marking information comprises the telephone number of the unfamiliar incoming call, the terminal marks the telephone number as a crank call;

step S204, when the terminal determines that the unfamiliar incoming call is a crank call, a marked uplink instruction is sent to a node where the data set is located according to the address of the node where the data set is located; wherein the tag _ UpLink instruction includes tag information.

The terminal determines that the unfamiliar incoming call is a harassing call, the unfamiliar incoming call can be judged as a harassing call by the user according to the call content after answering the call, or judged as a harassing call according to the identification results of the steps S201 to S203, or judged as a harassing call according to the experience of the user or other ways. No matter how the strange incoming call is determined as a crank call, the strange incoming call can be actively marked as a crank call and uploaded to the block chain for other terminals to use.

The terminal uploads the time including the telephone number to be marked and the mark to the block chain, namely, a uplink command is sent to the intelligent contract address of the block chain, and after the intelligent contract on the block chain receives the uplink command, the mark information is stored in a mark list of the intelligent contract. At this time, the terminal completes the uplink of the harassing call sign. The terminal of each node in the block chain can perform the marking operation, and the sharing of the marking information is realized.

In other embodiments, the method further comprises:

step S11, the terminal generates account information according to the address of the digital wallet and the account password;

step S12, when the terminal sends the marking uplink instruction to the node where the data set is located, paying the token in the digital wallet according to the address of the digital wallet; wherein the marked uplink command further includes the account information.

In order to prevent the user from maliciously tagging the phone number, an anti-malicious mechanism needs to be introduced. Here, it is implemented using digital currency in the blockchain. The user can register an account for using the harassing call function on the blockchain, and the user registers according to the digital wallet information in the blockchain and the set account password. Here, the terminal generates account information from the digital wallet information and the account password.

When the terminal needs to mark a crank call, the account information needs to be uploaded to an intelligent contract in the block chain together through a mark uplink command, and the intelligent contract deducts a certain token according to the account information. That is, by restricting the marking of a harassing call by paying a token, it is possible to prevent a malicious marking to some extent.

Of course, to encourage users to mark true nuisance calls, a degree of reward may be applied to the user based on the quality of the user mark to offset tokens paid out by the user mark. Corresponding rewards can be made according to the number of times the marked telephone number is marked by other people, for example, if one telephone number is marked as a harassing call by a plurality of people, the first person marking the telephone number can obtain the reward; for another example, when a telephone number is marked as a nuisance call by a terminal, all users who have previously marked the same telephone number may receive a corresponding reward.

In other embodiments, the method further comprises:

step S13, when the terminal determines that the strange incoming call is not a crank call, sending an anti-tag uplink instruction to the node where the data set is located according to the address of the node where the data set is located; wherein, the anti-mark uplink command comprises a telephone number, an anti-mark identifier and a mark time.

In order to prevent the non-crank telephone numbers from being marked or the original crank telephone numbers from being used by others and no longer being crank telephones, it is necessary to perform a reverse marking in the blockchain to mark the corresponding telephone numbers as non-crank telephones. Here, an anti-tag uplink command is sent to the smart contract in the blockchain in a method similar to the tagging of the crank call, and the anti-tag uplink command further comprises an anti-tag identifier besides the telephone number and the tag time, and the anti-tag identifier is used for indicating that the telephone number is tagged as a non-crank call.

The embodiment of the application provides a method for preventing harassing calls, which is applied to intelligent contracts of block chains, and as shown in fig. 3, the method comprises the following steps.

Step S301, a node where a data set is located receives a marked uplink command sent by a first terminal in a block chain; the tag _ UL instruction comprises tag information;

step S302, the data set stores the marking information in a marking list;

step S303, transmitting the mark list to other terminals in the block chain.

The node where the data set is located is the node where the intelligent contract in the block chain is located. And the intelligent contract records the marked telephone number and the marked time according to the marked uplink command sent by the first terminal. And generating marking information according to the telephone numbers and the marking time, namely, forming a piece of marking information by each marked telephone number and the time (namely, the marking time) of the corresponding uploading marking uplink instruction, establishing a marking list by the intelligent contract, and storing each piece of marking information in the marking list. The intelligent contract adds a new piece of marking information to the marking list every time the intelligent contract receives the new piece of marking information.

When the terminal downloads the mark list or when the mark list is updated, the intelligent contract sends the mark list to the terminals of all the nodes of the block chain, so that the terminals on the block chain share the mark information. Here, the update of the tag list may be a periodic update, or may be an update when the intelligent contract acquires tag information of a new uplink. When a new marking information cochain exists and a marking list is carried out, the intelligent contract sends the updated marking list to the terminal of each node; or when a terminal requests to download the mark list, the intelligent contract sends the current mark list to the terminal; the tag list may also be sent to the terminals of the respective nodes periodically.

In other embodiments, the marked uplink instruction further comprises: an address of a digital wallet of the first terminal; the method further comprises the following steps:

and step S21, deducting the token from the digital wallet of the first terminal by the node where the data set is located according to the address of the digital wallet of the first terminal.

Here, the node where the data set is located, that is, the smart contract on the block chain, may obtain, according to the marked uplink instruction sent by the first terminal, the digital wallet address corresponding to the account information of the first terminal. In order to prevent malicious signature nuisance calls, when a new uplink command is received by the smart contract, certain tokens are deducted according to the address of the digital wallet. The token can be digital currency, real currency, cash voucher, coupon or other reward and punishment mechanism.

In other embodiments, the method further comprises:

step S22, the node where the data set is located determines, according to the tag uplink command, that the phone number in the tag uplink command is tagged by the second terminal before the current tagging time and is stored in the tag list;

and step S23, transmitting a reward token to the digital wallet of the second terminal according to the mark uplink instruction transmitted by the second terminal.

To encourage users to mark nuisance calls, it is desirable to give appropriate rewards to high quality marks. The reward criteria herein may be used to assess the quality of the token by the number of times the telephone number is re-signed by another terminal after the token. When the first terminal marks, the intelligent contract can search whether the telephone number is marked before the marking according to the marking time, and if the telephone number is marked by the second terminal, the intelligent contract rewards the second terminal. Thus, the earliest marked terminal, the user of which receives the most reward, can receive the most reward. Of course, it is also possible to award the second terminal only once, for example, when the number of times that the telephone number marked by the second terminal is marked by the other terminal after the marking time reaches a certain number, the award is given to the second terminal.

The rewarding form can still issue a rewarding token to the digital wallet corresponding to the rewarded terminal through the digital wallet and the intelligent contract, so that on one hand, the token consumed during marking can be offset, and the situation that the marking of a harassing call by a user is negative is avoided; on the one hand, additional rewards can be obtained, giving rewards for high quality marks.

In other embodiments, the method further comprises:

step S31, the node where the data set is located receives the anti-tag uplink command sent by the first terminal; wherein, the anti-mark uplink command comprises a telephone number, an anti-mark identifier and a mark time;

step S32, respectively counting the marked times N and the unmarked times M of the telephone number according to the unmarked uplink command; wherein N and M are positive integers greater than or equal to 0;

and step S33, when M is larger than or equal to N, deleting all the mark information with the telephone number from the mark list.

In order to prevent someone from maliciously tagging their own telephone number, or telephone numbers that were once tagged as nuisance calls are no longer nuisance calls, for example, the operator has been re-released for use by other users. Then the number cannot be made to exist in the tag information of the blockchain as a crank call all the time, and is permanently identified as a crank call. Here, an anti-tagging strategy is proposed to prevent a number from being permanently identified as a nuisance call.

When a user marks through a terminal, the user can be divided into a mark and an anti-mark, the mark uplink instruction is used for uploading the telephone number marked as a harassing call to the block chain, and the anti-mark uplink instruction is used for uploading the telephone number of a non-harassing call to the block chain. The anti-tag _ UL instruction can be distinguished from the tag _ UL instruction by carrying an anti-tag flag. For example, a 0 bit is added after the telephone number as the anti-tag identification. It is also possible to add different identifiers to the tag uplink command and the anti-tag uplink command, for example, in the tag uplink command, a bit 1 is added after the telephone number as the identifier of the harassing call, and in the anti-tag uplink command, a bit 0 is added after the telephone number as the identifier of the non-harassing call.

When the anti-marking times of the same telephone number are larger than or equal to the marking times, the intelligent contract automatically determines the telephone number as a non-harassing call and deletes all the marking information of the telephone number in the current marking list, so that the telephone number cannot be found in the marking information acquired by the terminal and cannot be identified as a harassing call. The smart contract may provide token rewards to the terminal account providing the anti-branding to encourage the user's anti-branding behavior, facilitating sufficient data volume to ensure the accuracy of the branding.

In practical application, the marking information in the marking list may not be deleted, the intelligent contract records the times of marking and inversely marking the same telephone number, and both the times of marking are provided to the terminal, and the terminal may decide which kind of processing is performed on the telephone number according to the data provided by the intelligent contract.

The embodiment of the application provides a method for preventing harassing calls, which is suitable for a smart phone terminal, wherein the smart phone terminal is required to have a data connection function such as a wireless network or WIFI. As shown in fig. 4, the method comprises the steps of:

step S401, storing an intelligent contract on a block chain network;

the intelligent contract can be regarded as a data set, which mainly realizes the following three functions:

the intelligent contract management method comprises the steps that firstly, all marking information is used for being collected, and the marking information of a user is sent to a contract address of an intelligent contract;

and secondly, the intelligent contract is used for providing a query service, and a user can query all the mark records and the mark number information through the contract address of the intelligent contract.

Third, the smart contract may also include a digital wallet address that rewards the user based on the user's token and the validity of the token.

The intelligent contract address can be preset by the terminal, and can also be published through media such as official networks, specifications and the like for users to obtain and use.

And S402, setting a menu in the call record of the terminal, wherein the menu comprises the digital wallet address, the password and the intelligent contract address of the user.

Here, the digital wallet address requires the user to apply for, and if the mobile phone has the wallet function, the wallet address on the mobile phone can be directly used, and the wallet address is used for transmission verification to ensure interaction with the smart contract on the blockchain.

Step S403, the terminal automatically downloads the existing marking information from the intelligent contract address through the network;

the mark information can include mark number and mark time, if downloaded, the latest mark information after the mark time of the last mark can be automatically downloaded and stored in a local specific directory, and redundant information is deleted by statistically combining the downloaded mark information, so that the occupation of local space is reduced.

Step S404, the terminal records the marked data in the mark information according to the mark of the user;

the uplink refers to that after the user marks successfully, the terminal automatically sends an instruction to the intelligent contract address, and the instruction contains information such as the initiating time of the instruction, the intelligent contract address, the digital wallet address of the user, transmission cost, number and the like. Here, the transmission can be performed only in the WIFI network, and also in both the WIFI network and the data network.

Step S405, when the terminal receives an incoming call, the terminal inquires local marking information, checks whether the number is marked as a crank call, and if the number is marked, the number is displayed as a crank call.

In other embodiments, a particular token (token) in the user's digital wallet is deducted when the token information is uplinked after the user has signed on the terminal.

Here, the user needs to consume a certain token for each marking. The purpose is to prevent the user from marking the number uplink at will, i.e. to prevent rules for malicious marking.

In other embodiments, after the user marks on the terminal, whether other users mark the same number is judged, and if so, the token is automatically returned to the user through the intelligent contract to be used as the reward. For example, when user a marks a number a, user a consumes the token when marked, the subsequent system finds that user B also marks the same number a, and user B consumes the token but gives user a reward; when user C also marks number a, user C consumes the token, giving user A and user B a reward. Alternatively, to better enhance the accuracy of the marking, a reward may be given when the marking reaches a certain amount. For example, user a marks number a, and when other N users all mark number a subsequently, user a is given a certain reward. If no one has marked the number a again, the user a will not receive any more rewards. This is done to encourage users to actively participate in the tagging collaboration to prevent nuisance calls, and to prevent malicious tagging of users.

In other embodiments, in order to prevent the user from randomly marking or unmarking, or in order to prevent the marked number from being used by the harasser and released to the normal user by the operator, the terminal provides an anti-marking function, and the anti-marked number is also linked with corresponding information. For example, when a crank call is marked, the number information sent in uplink is 13900000000_1_0, wherein the first 11 digits are marked telephone numbers, and the middle 1 represents marked crank calls; when the number tag is cancelled, the number information sent by the uplink is 13900000000_0_1, and the last 1 represents the anti-tag. The intelligent contract automatically counts each number in real time, and the terminal can be called or downloaded for use. When the counted number of times of anti-marking is larger than or equal to the marked number, the terminal side can automatically set the number as a non-harassing call.

By the method in the embodiment, when the terminal refreshes the version, or changes the mobile phone, the operator and the like, the intelligent contract is logged in again through the account and the password to obtain the intelligent contract address and the digital wallet address. Therefore, the marking content of the anti-harassing call is not restricted by the replacement of the mobile phone, the operator or the application program, and the union effect of the anti-harassing call is achieved.

The embodiment of the present application provides another method for preventing a harassing call, as shown in fig. 5, the method includes the following steps:

step S501, the terminal sets the digital wallet address, the password and the intelligent contract address of the user through the call record setting menu;

step S502, the terminal downloads all the mark number information associated with the intelligent contract address to a local directory according to a predefined rule;

step S503, the terminal carries out merging statistical processing on the downloaded data and deletes redundant information to reduce the occupation of space;

step S504, the terminal selects the number in the call record to be marked as a crank call, or carries out reverse marking;

the anti-marking means that the terminal selects the number in the call record and marks the number as a non-harassing call;

step S505, the terminal sends a chaining instruction to the intelligent contract address, wherein the instruction comprises the information of the instruction initiating time, the intelligent contract address, the user digital wallet address, the transmission cost, the number and the like;

step S506, the intelligent contract stores the related content in the received uplink command in the blockchain network;

step S507, the intelligent contract awards the token reward to the terminal according to the reward rule.

In this embodiment, when the terminal side receives an unfamiliar incoming call, the incoming call anti-harassment needs to be realized according to the following steps:

step S41, when the terminal receives an unfamiliar call, all the marking information under the local directory is inquired;

step S42, the terminal judges whether the label information has a record that the strange incoming call number is labeled as a harassing call;

step S43, if the record that the unfamiliar incoming call number is marked as a harassing call exists in the marking information, the unfamiliar incoming call number is displayed as a harassing call;

and step S44, if no strange incoming call number record of the number exists in the marking information, the number is not processed, and the incoming call state is displayed normally.

According to the method and the device, identification of the incoming call number can be guaranteed by using the block chain technology, particularly identification of a crank call can be free from influences of factors such as changing a telephone number, changing a number, changing an operator and the like, and as long as the block chain has the recorded number, the marking information of the incoming call on the block chain can be acquired anytime and anywhere under the condition of a data network so as to identify whether the incoming call is a crank call or not, and the data can be used by any person or any mechanism on the block chain, so that a union effect, namely data sharing is achieved finally. The block chain network adopted in the embodiment of the application can be an existing block chain network, such as Ethereum or EOS, or a newly built block chain network.

The embodiment of the application also provides a device for preventing the harassing call, which comprises all the units and all the modules included by all the units, and can be realized by a processor in the terminal; of course, it may also be implemented by logic circuitry; in implementation, the processor may be a Central Processing Unit (CPU), a Microprocessor (MPU), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), or the like.
