[0050] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0051] It should be noted that the data processing method, device, equipment and readable storage medium provided by the present invention can be used in the field of network security or finance. The above is only an example and does not limit the application field of the data processing method, device, equipment and readable storage medium provided by the present invention.

[0052] A data processing method provided in an embodiment of the present application is applied to, but not limited to, predicting the update time of a public account and sending a reminder instruction for the public account, so as to prompt the process of indicating that the public account is at risk of loss of connection. Figure 1 A specific implementation process of a data processing method provided in an embodiment of the present application is as follows: Figure 1 As shown, the method includes:

[0053] S101. Obtain account information, historical update information of contact information, and basic information of a public account.

[0054] In this embodiment, the basic information includes the nature of the enterprise, the scale of the enterprise and the structure of the enterprise. The historical update information includes the historical update time, and the account information includes the nature of the account and the transaction type.

[0055] S102: Obtain the time interval between every two adjacent historical update times in the historical update information of the contact information of the public account.

[0056] S103: Take the average value of the time interval as a candidate update period.

[0057] S104. Obtain the security level of the public account based on the account information.

[0058] It should be noted that the security level indicates the transaction security of the public account and the enterprise security. There are many methods for obtaining the security level. For example, according to the account nature of the public account, the enterprise security level corresponding to the account nature of the public account is obtained from the preset enterprise security level correspondence relationship. According to the transaction type of the public account, the transaction security level corresponding to the transaction type of the public account is obtained from the preset transaction security level correspondence relationship. The transaction security level and the enterprise security level are weighted and added to obtain the security level of the public account.

[0059] It should be noted that the higher the security level, the higher the security protection requirements for public accounts. For example, public accounts with frequent money transactions have a high security level.

[0060] S105. Obtain a similar account set of the public account based on the basic information.

[0061] In this embodiment, the similar account set includes at least one similar account, and the similar account is an account that meets a preset similarity condition. The similarity condition includes: the similarity between the basic information and the basic information of the public account is greater than a preset similarity threshold.

[0062] Methods for obtaining the similarity between two public accounts include:

[0063] By establishing a rating function to score the similarity of the enterprise nature, enterprise scale and enterprise structure, the overall similarity of the enterprise is obtained, and thus the similarity of the public account is obtained. The specific similarity calculation method can be referred to the prior art.

[0064] S106: Obtain a similar update period based on the historical update information of the contact information of each similar account.

[0065] In this embodiment, the similar update period is an average value of the update periods of the contact information of similar accounts.

[0066] S107: Determine whether the similar update period is smaller than the candidate update period.

[0067] S108: If the similar update period is smaller than the candidate update period, weighted addition is performed on the candidate update period and the similar update period to obtain a weighted update period.

[0068] It should be noted that if the similar update cycle is smaller than the candidate update cycle, it means that the update cycle of the similar account is small, that is, the update frequency is high. The larger the difference between the candidate update cycle and the similar update cycle, the larger the weighting coefficient of the similar update cycle.

[0069] S109: Obtain an update cycle of the contact information according to the security level and the weighted update cycle.

[0070] In this embodiment, the update cycle of the contact information is inversely correlated with the security level, and the update cycle of the contact information is positively correlated with the candidate update cycle. That is, the higher the security level, the shorter the update cycle, and the longer the candidate update cycle, the longer the update cycle.

[0071] It can be seen from the above technical solution that the data processing method provided by the present application obtains the historical update information of the account information of the public account and the contact information of the public account, the historical update information includes the historical update time, and the account information includes the account nature and transaction type. Based on the account information and the historical update information, the update cycle of the contact information is obtained. Based on the update cycle and the first historical update time, the predicted update time is obtained. In response to reaching the predicted update time, a prompt instruction is sent, and the prompt instruction indicates that there is a risk of expiration of the contact information of the public account. It can be seen that compared with the passive update mechanism of the prior art, the present method obtains the predicted update time through the historical update information of the account information of the public account and the contact information of the public account, and sends the prompt instruction in time, thereby reducing the risk of loss of contact with the public account.

[0072] Furthermore, when the similar update cycle is smaller than the candidate update cycle, the method performs weighted addition of the candidate update cycle and the similar update cycle to obtain a weighted update cycle, taking into account the update rules of the contact information of accounts similar to the public accounts to improve the accuracy of the update cycle.

[0073] It should be noted that Figure 1 This is only an example of an optional specific implementation method of data processing, and the present application also includes other specific implementation methods, for example,

[0074] In summary, the data processing method provided in the embodiment of the present application can be summarized as follows: Figure 2 The process shown is as follows Figure 2 As shown, the method includes:

[0075] S201. Obtain account information of a public account and historical update information of contact information of the public account.

[0076] In this embodiment, the historical update information includes the historical update time, and the account information includes the account nature and transaction type.

[0077] S202: Obtain the update cycle of the contact information based on the account information and the historical update information.

[0078] There are multiple methods for obtaining the update period of the contact information based on the account information and the historical update information. For a specific optional obtaining method, see the above embodiment, which will not be described in detail in this embodiment.

[0079] S203: Obtain a predicted update time based on the update cycle and the first historical update time.

[0080] In this embodiment, the first historical update time is the last historical update time in the historical update information. For example, the last historical update time is October 21, and the update cycle is 3 months. The predicted update time is 3 months after the historical update time (October 21), that is, January 21.

[0081] S204: In response to reaching the predicted update time, sending a prompt instruction.

[0082] In this embodiment, the prompt instruction indicates that the contact information of the public account is at risk of being out of date.

[0083] It should be noted that there are many methods for sending prompt instructions, and the details can be found in the prior art.

[0084] It can be seen from the above technical solution that the data processing method provided by the present application obtains the historical update information of the account information of the public account and the contact information of the public account, the historical update information includes the historical update time, and the account information includes the account nature and transaction type. Based on the account information and the historical update information, the update cycle of the contact information is obtained. Based on the update cycle and the first historical update time, the predicted update time is obtained. In response to reaching the predicted update time, a prompt instruction is sent, and the prompt instruction indicates that there is a risk of expiration of the contact information of the public account. It can be seen that compared with the passive update mechanism of the prior art, this method obtains the predicted update time through the historical update information of the account information of the public account and the contact information of the public account, and sends a prompt instruction in time to reduce the risk of loss of contact with the public account.
