For example, as shown in fig. 3, the telephone numbers registered in the blockchain network all have corresponding user account numbers, and when a user applies for a new telephone number, an operator terminal in the blockchain network signs the telephone number by using a private key of the operator terminal to generate a signature number, and verifies real name information of the user in the following way: at the operator end, signature information is obtained by signing the real name information of the user through the public key of the national official personal real name information authentication mechanism, broadcast is carried out through the blockchain network, the field is sent to other nodes on the blockchain network, after receiving the signature information, the other nodes send the signature information to the national official personal real name information authentication mechanism for authentication, after all the nodes receive information of successful authentication, the authentication success is indicated, after the authentication success, the signature number and the signature information can be encrypted to obtain a user account, encryption can be carried out through a hash algorithm, and mapping of the telephone number and the user account is established.

In this way, by judging whether the third number is registered on the blockchain network and judging the operation instruction for the telephone call corresponding to the third telephone number according to the judging result by the second intelligent contract, the operation instruction for the telephone call corresponding to the third telephone number can be accurately and efficiently obtained, the harassment call can be efficiently judged, and the harassment call interception efficiency is improved.

In one implementation, the determining, according to the second smart contract, an operation instruction for the incoming call includes:

acquiring a first total number of calls of the third telephone number;

if the total number of the first incoming calls is less than or equal to N, determining that the operation instruction is to automatically disconnect the incoming call;

if the total number of the first calls is equal to the sum of N and 1, determining that the operation instruction is to automatically disconnect the call, and the blockchain network sends a first notification message to the terminal, wherein the first notification message is used for notifying the terminal that the call of the third telephone number has been received;

if the first incoming call total number is greater than or equal to the sum of N and 2, determining that the operation instruction is to make the incoming call;

And setting the first incoming call interception policy by the target user when setting the first incoming call interception policy, wherein N is a positive integer.

Specifically, the blockchain network obtains a first total number of calls of the third phone number, and the blockchain network determines an operation instruction for the phone call corresponding to the third phone number according to the first call interception policy and the first total number of calls in the second intelligent contract.

If the total number of the first calls is less than or equal to N, determining that the operation instruction for the call corresponding to the third phone number is automatic disconnection of the call, and sending the operation instruction to the terminal of the target user.

If the total number of the first incoming calls is greater than or equal to the sum of N and 2, that is, if the total number of the first incoming calls is greater than or equal to n+2, determining that the operation instruction for the telephone call corresponding to the third telephone number is a call incoming call, and sending the operation instruction to the terminal of the target user.

When the target user sets the first incoming call interception policy, setting N in the first incoming call interception policy, wherein N is a positive integer.

In this way, if the third telephone number is not registered in the blockchain network, the operation instruction of the telephone call corresponding to the third telephone number is determined by judging the relation between the total number of the first calls of the third telephone number and N set in the first call interception policy, so that the harassment success rate of harassment calls is effectively reduced, and the telephone call can be switched on only after the total number of the telephone calls reaches the call number set by a user, thereby avoiding the interception error under the characteristic condition.

If the total number of the second calls is equal to the sum of M and 1, determining that the operation instruction for the call is to automatically disconnect the call, and the blockchain network sends a second notification message to the terminal of the target user, wherein the second notification message is used for notifying the target user that the terminal of the target user has received the call of the third phone number;

if the second incoming call total number is greater than or equal to the sum of M and 2, determining that the operation instruction for the telephone incoming call is to put through the telephone incoming call;

and setting the M and the preset trust threshold in the first incoming call interception policy by the target user when the first incoming call interception policy is set, wherein M is a positive integer.

Specifically, if the third phone number is registered in the blockchain network, the third phone number has a corresponding first trust factor, and the blockchain network will first determine a relationship between the first trust factor of the third phone number and a preset trust threshold.

If the total number of the second calls is less than or equal to M, determining that the operation instruction for the call corresponding to the third phone number is automatic disconnection of the call, and sending the operation instruction to the terminal of the target user.

If the total number of the second calls is equal to the sum of M and 1, that is, the total number of the second calls is equal to M+1, determining that the operation instruction for the call corresponding to the third phone number is automatic disconnection of the call, sending the operation instruction to the terminal of the target user, and sending a first notification message to the terminal of the target user, wherein the first notification message is used for notifying that the terminal of the target user has received the call of the third phone number.

If the total number of the second calls is greater than or equal to the sum of M and 2, that is, if the total number of the second calls is greater than or equal to M+2, determining that the operation instruction for the phone call corresponding to the third phone number is a call, and sending the operation instruction to the terminal of the target user.

When a target user sets a first incoming call interception policy, setting M and a preset trust threshold in the first incoming call interception policy, wherein M is a positive integer.

Therefore, the trust degree of the third telephone number can be judged through the first trust factor, the telephone incoming call of the third telephone number with low trust factor value can be limited by combining with the second intelligent contract, the harassment success rate of harassment calls is effectively reduced, the third telephone number with low trust factor value can be connected only after the total number of the second telephone number reaches the preset call times of the target user, the false interception under the characteristic condition is avoided, and the harassment call interception efficiency is improved.

wherein, T represents the first trust factor, T represents the using time of the third telephone number, a and c represent the calling number of times of the user corresponding to the third telephone number, k and d represent the number of times that the third telephone number is marked as a harassment call by the user x, T _x And the second trust factor of the user x is represented, when the e and the y represent the times of marking the calling user by the user corresponding to the third telephone number when the third telephone number is called, the j represents the validity of marking the calling user by the user corresponding to the third telephone number, if the validity is valid, the j is 0, and if the validity is invalid, the j is 1.

Wherein ln ^(t) The longer the length of time indicated as registered and used by the third telephone number means that the greater the probability that the user account to which the third telephone number corresponds is a normal user account, the correspondingly higher the third telephone number credit level has a positive effect on its credit factor, whereas most nuisance calls are new telephone numbers and will not be used for a long time, and therefore the life cycle of the nuisance call is relatively short.

In the above formulaA credit record representing the calling behaviour of this third telephone number, whose first trust factor is reduced if the third telephone number is marked as a nuisance call, can be derived from the formula. And if the corresponding second trust factor of the victim is large, the higher the mark reliability thereof, the more reliable the third telephone numberThe greater the impact of the first trust factor.

In the above formulaWhen the third telephone number is called, the user corresponding to the third telephone number carries out marking data statistics on the harassment behaviors of the caller, if the blockchain network judges that the marking behaviors of the user corresponding to the third telephone number are valid, the first trust factor of the user corresponding to the third telephone number can be rewarded relatively, and if the marking of the user corresponding to the third telephone number is invalid, the first trust factor of the user corresponding to the third telephone number can be reduced correspondingly. In this way, the user can be encouraged to effectively mark, while preventing malicious marking actions by the user.

Therefore, the credit degree of one user is evaluated by setting the trust factor, the user can punish the harassment call user, the trust factor is reduced, the user is given greater authority and operation space, and the user experience and the enthusiasm for harassment call marking are improved.

4) If the terminal of the target user receives the call, the terminal cannot determine whether the call is a harassment call, and then sends a third number corresponding to the call to the blockchain network.

As shown in fig. 5, if a terminal of a target user receives a call, it may first determine whether a third phone number corresponding to the call is in a local blacklist of the terminal or in a local whitelist, if the third phone number is in the local blacklist, the call is automatically suspended, if the third phone number is in the local whitelist, the call is automatically connected, if the third phone number is neither in the local blacklist nor in the local whitelist, it is determined whether the third phone number is in a bloom filter preset locally, the bloom filter stores data of a whitelist number library in a blockchain network, and if the third phone number is not in the bloom filter, the third phone number is sent to the blockchain network.

5) And if the blockchain network receives a third telephone number corresponding to the telephone call sent by the terminal, determining an operation instruction aiming at the telephone call according to the second intelligent contract and the third telephone number, and sending the operation instruction to the terminal.

As shown in fig. 5, if the third phone number sent by the terminal of the target user is received, it may be first determined whether the third phone number is in a white list number bank in the blockchain network, if the third phone number is in the white list number bank in the blockchain network, an operation instruction for completing the call is returned to the terminal of the target user, if the third phone number is not in the white list number bank in the blockchain network, it is determined whether the third phone number is already registered in the blockchain network, if the third phone number is not registered in the blockchain network, the blockchain network sends the third phone number to the second intelligent contract, the first total number of calls of the third phone number is obtained, if the first total number of calls is less than or equal to N, it is determined that the operation instruction for completing the call corresponding to the third phone number is an automatic disconnection call, and the operation instruction is sent to the terminal of the target user.

If the third telephone number is registered on the blockchain network, a first trust factor corresponding to the third telephone number is obtained, and the blockchain network firstly judges the relation between the first trust factor of the third telephone number and a preset trust threshold.
