[0043] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "include..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0045] Before describing the technical solutions provided by the embodiments of the present application, in order to facilitate the understanding of the embodiments of the present application, the present application first specifically describes the problems existing in the related art:

[0046] With the continuous development of the Internet, users may go to the resource issuer for verification based on the resource voucher issued by the resource issuer, such as the redemption code. The current verification process mainly includes three stages. The first stage is that the resource issuer generates the resource voucher based on the server. The second stage is that the server issues the resource voucher to the user's user device. The third stage is that the user goes to the resource issuer for verification based on the resource voucher of the user device. However, the above process may have security issues such as the leakage of the user's resource voucher and the theft of the user's resource voucher by others, resulting in a poor user experience.

[0047] Based on this, the embodiment of the present application provides a method, device, equipment, medium and product for generating a resource credential, which can solve the above problems.

[0048] In some embodiments, Figure 1 As shown, the embodiment of the present application provides a method for generating a resource credential, which may include the following steps S110-S210:

[0049] S110: The first user device sends first user request information for obtaining a resource credential to the second device, where the first user request information includes a first user identifier and a credential factor, and the credential factor is associated with the second user identifier.

[0050] The user can send a first user request to obtain a resource credential to the second device based on the first user device. Here, the second device can be a server device. The second user device of the resource issuer can generate a corresponding verification tool such as a redemption code associated with the second user identifier based on the server in advance. The second user identifier is the user identifier of the resource issuer.

[0051] Here, the first user request information includes a first user identifier and a credential factor. The first user identifier is an identifier for identifying the user, such as the user's mobile phone number. The credential factor is a credential factor associated with the verification tool. The credential factor can be used to generate a resource voucher, and the subsequent user can redeem the resource based on the resource voucher. It is conceivable that the credential factor can be associated with both the first user identifier and the second user identifier, representing the corresponding unique user and resource issuer.

[0052] S120: The first device receives first request information sent by the second device, where the first request information includes a first user identifier.

[0053] The first device may receive the first request information sent by the second device, and the first request information may include the above-mentioned first user identification. For example, the first device sends the above-mentioned user's mobile phone number to the second device. Here, to prevent user information leakage, the second device may send an encrypted mobile phone number to the first device. The encrypted mobile phone number is the mobile phone number that the first device encrypts when the user obtains the first card identification from the first device based on the mobile phone number and sends it to the second device.

[0054] Here, the first device is a device that stores the user's SIM card identifier.

[0055] S130: The first device determines a first device identifier corresponding to the first user identifier from a correspondence between user identifiers and user device identifiers, and sends first verification information to a first user device corresponding to the first device identifier.

[0056] The first device can determine the first device identifier corresponding to the first user identifier from the correspondence between the user identifier and the user device identifier. Here, the above correspondence is the identifier included in the request information when the first user device sends a request information for obtaining the first card identifier to the first device. The first device can establish a correspondence based on the first user device sent by the user and the first device.

[0057] After determining the first device identifier, the first device may send first verification information to the first user device corresponding to the first device identifier, for example, sending pop-up information to the first user device.

[0058] S140: The first user equipment displays first verification information.

[0059] The first user device may display the first verification information, for example, the first user device may display the first verification information based on Figure 2 The pop-up window information shown displays the first verification information.

[0060] S150: The first user equipment receives a user input for the first user equipment, where the input includes a first card identifier of a SIM card for user identification.

[0061] The first user device may receive user input for the first user device, where the input may include a first card identifier of a user identity SIM card, and the first card identifier may be an identifier sent by the first device to the first user device when the first device receives the request information sent by the first user device.

[0062] S160: The first user equipment sends a first card identifier to the first device.

[0063] The first user equipment may send the first card identifier to the first device.

[0064] S170: The first device detects whether the stored data of the first device includes the first card identifier, and obtains a first detection result.

[0065] The first device can detect whether the stored data of the first device includes the above-mentioned first card identifier to obtain a first detection result. It can be imagined that when the user's first user device is connected to the SIM card, the first device will store the first card identifier associated with both the first user identifier and the first device identifier.

[0066] S180: When the first detection result includes that the first card identifier is included in the stored data of the first device, the first device generates a first identifier and sends the first identifier to the second device.

[0067] In the case that the first detection result includes the first card identifier in the stored data of the first device, it indicates that the first card identifier is authentic and valid, and the first device may generate the first identifier and send the first identifier to the second device.

[0068] In some examples, when the first device detects whether the stored data of the first device includes the first card identifier, it may generate a detection task in the system log, the detection task may carry a task identifier, and the first device may send the task identifier to the second device.

[0069] It can be imagined that the first device will send the above-mentioned first identification to the second device only when the first device determines that the first detection result includes the first card identification included in the stored data of the first device. When the first device determines that the first detection result includes the first card identification not included in the stored data of the first device, the first device will not send the above-mentioned first identification to the second device.

[0070] S190: The second device sends the credential factor, the first user identifier, and the first identifier to the blockchain device.

[0071] S200: The blockchain device generates a resource credential based on the credential factor, the first user identifier, the first identifier, and the first timestamp, and sends the resource credential to the second device.

[0072] The blockchain device can use the smart contract to generate a resource certificate based on the certificate factor, the first user identifier, the first identifier and the first timestamp. Here, the first timestamp can be the timestamp of the blockchain device receiving the above-mentioned certificate factor, the first user identifier and the first identifier. After the blockchain device generates the resource certificate, it can send the resource certificate to the second device.

[0073] In some examples, the smart contract records a generation task when generating a resource credential, and the generation task may carry an identifier, and the resource credential may be generated based on the identifier, the credential factor, the first user identifier, the first identifier, and the first timestamp.

[0074] In some examples, the credential factor is associated with the first user identifier, and the blockchain device can detect all credentials associated with the first user identifier based on the first user identifier, and detect whether all credentials include the resource factor, thereby detecting the validity of the credential factor. When it is detected that the credential includes the credential factor, a resource credential is generated based on the credential factor, the first user identifier, the first identifier, and the first timestamp.

[0075] In some examples, the blockchain device can detect whether the timestamp included in the above-mentioned credential factor is within a preset time period. When it is determined that the timestamp included in the credential factor is within the preset time period, a resource credential can be generated based on the credential factor, the first user identifier, the first identifier, and the first timestamp.

[0076] S210: The second device sends a resource credential to the first user device, wherein the resource credential is associated with the second user identifier.

[0077] When receiving the resource credential, the second device may send the resource credential to the first user device corresponding to the first user identifier based on storing the resource credential and based on the first user identifier included in the resource credential.

[0078] In the embodiment of the present application, when the first device receives the first request information sent by the second device, the first device identifier corresponding to the first user identifier is determined from the correspondence between the user identifier and the user device identifier, and the first verification information is sent to the first user device corresponding to the first device identifier, so that the user inputs the first card identifier based on the first verification information displayed by the first user device, receives the user's input based on the first verification information, and sends the first card identifier of the user identity identification SIM card to the first device, and detects whether the first card identifier is included in the storage data of the first device by the first device to obtain a first detection result, thereby verifying the user identity, and then, when the first detection result includes that the first card identifier is included in the storage data of the first device, the first identifier is generated and sent to the second device, so that the second device sends the credential factor, the first user identifier and the first identifier to the blockchain device, so that the blockchain device generates the resource credential based on the credential factor, the first user identifier, the first identifier and the first timestamp, and sends the resource credential to the second device, so that the second device sends the resource credential to the first user device, thereby realizing the real-time generation of the resource credential, avoiding the leakage of the resource credential, improving the security of the resource credential, and improving the user experience of the user's subsequent redemption of resources based on the resource credential.

[0079] In some embodiments, Figure 3 As shown, before the first device receives the first request information sent by the second device, the generating method may further include the following steps S310-S410:

[0080] S310: The first user device sends second user request information for obtaining a credential factor to the second device, where the second user request information includes a first user identifier.

[0081] Here, the first user device may send a second user request message for obtaining a credential factor to the first device, and it is conceivable that the credential factor is associated with both the first user identifier and the second user identifier. The first user identifier may be a mobile phone number.

[0082] S320: The first device receives second request information sent by the second device, where the second request information includes the first user identifier.

[0083] When receiving the first user identifier, the second device may send second request information to the first device, and the first device may verify the user identity based on the first user identifier included in the request information.

[0084] S330: The first device determines a first device identifier corresponding to the first user identifier from the correspondence between the user identifier and the user device identifier, and sends second verification information to the first user device corresponding to the first user identifier.

[0085] The first device identifier can determine the first device identifier corresponding to the first user identifier based on the correspondence between the user identifier and the user device identifier, and send the second verification information to the first user device corresponding to the first user identifier.

[0086] S340: The first user equipment displays the second verification information.

[0087] Similarly, the first user equipment can display the second verification information based on the above pop-up window format.

[0088] S350: The first user device receives a user input for the first user device, where the input includes a first card identifier.

[0089] The user may input the first card identification for the first user device.

[0090] S360: The first device receives the first card identifier sent by the first user equipment.

[0091] S370: The first device detects whether the stored data of the first device includes the first card identifier, and obtains a second detection result.

[0092] S380: When the second detection result includes that the first card identifier is included in the stored data of the first device, the first device generates a second identifier and sends the second identifier to the second device.

[0093] When the second detection result includes the first card identifier in the stored data of the first device, it indicates that the first card identifier is authentic and valid. The first device may generate a second identifier and send the first identifier to the second device.

[0094] Similarly, when the first device detects whether the first card identifier is included in the stored data of the first device, a detection task may be generated in the system log, the detection task may carry the first task identifier, and the first device may send the first task identifier to the second device. It is conceivable that the first task identifier is an identifier different from the aforementioned task identifier.

[0095] S390: The second device sends the first user identifier and the second identifier to the blockchain device.

[0096] S400: The blockchain device generates a credential factor based on the first user identifier, the second identifier, and the second timestamp, and sends the credential factor to the second device.

[0097] The blockchain device can generate a credential factor based on the first user identifier, the second identifier, and the second timestamp through a smart contract. The second timestamp can be a timestamp when the blockchain device receives the first user identifier and the second identifier.

[0098] In some examples, the smart contract records a generation task when generating a credential factor. The generation task may carry a new identifier, and a resource credential may be generated based on the new identifier, the first user identifier, the second identifier, and the second timestamp.

[0099] S410: The second device sends a credential factor to the first user device.

[0100] In the embodiment of the present application, when the first device receives the second request information sent by the second device, the first device identifier corresponding to the first user identifier is determined from the correspondence between the user identifier and the user device identifier, and the second verification information is sent to the first user device corresponding to the first device identifier, so that the first user device displays the second verification information, receives the user's input based on the second verification information, and sends the first card identifier to the first device. The first device detects whether the first card identifier is included in the storage data of the first device to obtain the second detection result, thereby verifying the user identity when generating the credential factor. Then, when the second detection result includes that the first card identifier is included in the storage data of the first device, the second identifier is generated and sent to the second device, so that the second device sends the second identifier and the first user identifier to the blockchain device, so that the blockchain device generates the credential factor based on the second identifier, the first user identifier and the second timestamp, and sends the credential factor to the second device, so that the second device sends the credential factor to the first user device, so that the user can subsequently generate a resource credential based on the credential to exchange resources, which is "double encryption" of the resource credential, improves the security of the resource credential, and improves the user experience of the user's subsequent exchange of resources based on the resource credential.

[0101] In some embodiments, Figure 4 As shown, in the case where the first detection result includes that the first card identifier is included in the stored data of the first device, after the first device generates the first identifier and sends the first identifier to the second device, the generation method may further include the following steps S510-S640:

[0102] S510: The first user equipment sends fourth user request information to the second user equipment, where the fourth user request information includes a resource credential.

[0103] After receiving the resource credential, the first user equipment may send fourth user request information including the resource credential to the second user equipment. The second user equipment is the user equipment of the resource issuer.

[0104] S520: The second user equipment sends third user request information to the second device, where the third user request information includes a second user identifier and a resource credential.

[0105] The second user device may send third user request information to the second device, where the third user request information includes a second user identifier and a resource credential, and the second user identifier may be a mobile phone number of a resource issuer.

[0106] S530: The first device receives third request information sent by the second device, where the third request information includes the second user identifier.

[0107] The first device may receive the third request information sent by the second device, and verify the user identity of the resource issuer based on the second user identifier included in the third request information.

[0108] S540: The first device determines a second device identifier corresponding to the second user identifier from the correspondence between the user identifier and the user device identifier, and sends third verification information to the second user device corresponding to the second device identifier.
