[0081] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0082] It should be noted that the terms "first," "second," etc., used in this application can be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from the second element. The terms "comprising" and "having," and any variations thereof, used in this application, are intended to cover non-exclusive inclusion. The term "multiple" used in this application refers to two or more. The term "and / or" used in this application refers to one of the embodiments, or any combination of multiple embodiments.

[0083] The resource transfer method provided in this application embodiment can be applied to, for example, Figure 1 In the application environment shown, the first wearable device 102 communicates with the second wearable device 104 via a network. In response to a resource transfer operation, the first wearable device 102 obtains plaintext reference information; the first wearable device 102 encrypts the plaintext reference information based on a first public key to obtain ciphertext reference information; the first wearable device 102 sends the ciphertext reference information to the second wearable device 104, so that the second wearable device 104 displays the plaintext reference information obtained by decrypting the ciphertext reference information based on a first private key corresponding to the first public key; the first wearable device 102, in response to a resource transfer authorization operation for the plaintext reference information, performs the resource transfer operation according to the plaintext reference information.

[0084] In some embodiments, taking smart glasses as the first wearable device and a smartwatch or smart bracelet as the second wearable device, the resource transfer method provided in this application will be described. Because smart glasses are small and easy to wear, space resources on them are very limited. They generally only support modules such as cameras, audio, and cellular communication, and do not support human-computer interaction modules such as touchscreens. This means that smart glasses usually cannot meet the user's resource transfer needs independently. Smartwatches and smart bracelets generally have modules such as touchscreens and buttons, but considering factors such as battery life and wearing position, they generally do not support cellular communication and camera modules. This means that smartwatches and smart bracelets usually cannot meet the user's resource transfer needs independently either. Therefore, if the functional characteristics of smart glasses and smartwatches (or smart bracelets) can be combined, with smart glasses providing resource transfer functions and smartwatches (or smart bracelets) providing human-computer interaction functions, not only can a multi-scenario resource transfer environment be provided for users, but hardware costs can also be reduced, computing power requirements can be decreased, and battery life can be improved. This application is based on this concept.

[0085] In one exemplary embodiment, such as Figure 2 As shown, a resource transfer method is provided, which can be applied to... Figure 1 Taking the first wearable device 102 as an example, the following steps are included:

[0086] S210, in response to a resource transfer operation, obtain plaintext reference information.

[0087] The resource transfer operation can be used to indicate a current resource transfer requirement. For example, the resource transfer operation can be at least one of an image acquisition operation and an image display request operation. Optionally, the image acquisition operation can be a user-triggered operation on an image acquisition control on a first wearable device, such as a click or long-press operation. The image display request can be generated in many ways; for example, it can be generated in response to a user-triggered operation on an image display control on a second wearable device, such as a click or long-press operation.

[0088] Here, the plaintext reference information can be understood as the plaintext reference resource transfer information required in the resource conversion scenario. For example, the plaintext reference information can be resource transfer information, including at least one of the following: resource output account information, resource receiving account information, amount of resource to be transferred, and type of resource to be transferred.

[0089] Optionally, the first wearable device and the second wearable device can collaborate to support different resource transfer methods, including resource transfer by scanning a graphic code and resource transfer by swiping a graphic code.

[0090] In one alternative implementation, a graphic code may be acquired in response to an image acquisition operation; the graphic code may be parsed to obtain plaintext first reference information.

[0091] The image acquisition operation is used to request image acquisition. This operation can be a trigger operation on the image acquisition control as described above, or it can be an image acquisition command input via voice; this application does not impose any limitations on this. Users can generate an image acquisition request by triggering the image acquisition control on the first wearable device, for example, by clicking or long-pressing.

[0092] The graphic code can be at least one of QR codes and barcodes.

[0093] Optionally, the graphic code can be a resource receiving graphic code; correspondingly, the first reference information plaintext can be resource receiving account information embedded in the graphic code, such as at least one of resource receiving account type and resource receiving account identifier. The graphic code can also be a resource output graphic code; correspondingly, the first reference information plaintext can be resource output account information embedded in the graphic code, such as at least one of resource output account type, resource output account identifier, and resource transfer information.

[0094] For example, in response to an image acquisition operation on a first wearable device, a graphic code in the current environment is acquired, and the acquired graphic code is parsed to obtain the first reference information plaintext. The method of parsing the graphic code can be based on a decoding rule corresponding to a preset encoding rule to decode the graphic code and extract the first reference information plaintext embedded in the graphic code. The preset encoding rule can be determined based on human experience or through extensive experimentation; this application does not impose any limitations on it.

[0095] In another alternative implementation, the plaintext of the second reference information can be obtained in response to an image display request.

[0096] The second reference information is used to generate the graphic code; the first reference information plaintext is the information obtained by parsing the collected graphic code.

[0097] The image display request is used to request the display of a graphic code. Users can generate an image display request by triggering an operation on the image display control on the second wearable device, such as a click or long press.

[0098] The graphic code can be at least one of QR codes and barcodes. Optionally, the graphic code can be a resource receiving graphic code or a resource output graphic code. The correspondence between different types of graphic codes and the plaintext of the second reference information is the same as the correspondence between the graphic code and the plaintext of the first reference information, and will not be elaborated here.

[0099] For example, an image display request sent by a second wearable device is received, and in response to the image display request, the plaintext of the second reference information is obtained.

[0100] S220: Encrypt the plaintext of the reference information based on the first public key to obtain the ciphertext of the reference information.

[0101] The first public key can be understood as the collaborative working public key between the first wearable device and the second wearable device. Optionally, the first public key can be randomly generated by the second wearable device.

[0102] Optionally, the first public key can be generated by the second wearable device and sent to the first wearable device; or the first public key can be carried in some information, which the second wearable device sends to the first wearable device, and the first wearable device obtains the key by parsing this information.

[0103] Optionally, the plaintext of the reference information can be encrypted using an asymmetric encryption algorithm based on the first public key to obtain the ciphertext of the reference information; alternatively, the plaintext of the reference information can be encrypted using an elliptic curve cryptography public key system based on the first public key to obtain the ciphertext of the reference information.

[0104] S230, send ciphertext of reference information to the second wearable device so that the second wearable device can display plaintext of reference information obtained by decrypting the ciphertext of reference information based on the first private key corresponding to the first public key.

[0105] The first private key and the first public key together form an asymmetric key pair. Correspondingly, the first private key can also be randomly generated by the second wearable device.

[0106] Understandably, the second wearable device randomly generates a first public key and a first private key, and encrypts and saves the first public key and the first private key for later use.

[0107] The process by which the second wearable device decrypts the ciphertext of the reference information based on the first private key corresponding to the first public key is described in the following embodiments.

[0108] S240, in response to a resource transfer authorization operation for plaintext reference information, performs a resource transfer operation based on the plaintext reference information.

[0109] Among them, the resource transfer authorization operation can be a user's confirmation operation for the plaintext of the reference information.

[0110] Optionally, the resource transfer authorization operation can be a user-triggered operation on a confirmation control corresponding to the plaintext of the first reference information displayed on the second wearable device, such as a click operation. Alternatively, the resource transfer authorization operation can be a user-scanning operation on the plaintext of the second reference information displayed on the second wearable device; for example, a user scanning the plaintext of the second reference information using a Point of Sale Terminal (POS) system.

[0111] In one alternative implementation, in response to a resource transfer authorization operation for a first reference information plaintext, a resource transfer operation can be performed based on the reference information plaintext and in conjunction with a resource transfer server.

[0112] In another alternative implementation, in response to a resource transfer authorization operation for the second reference information plaintext, a resource transfer operation can be performed based on the reference information plaintext and in conjunction with a resource transfer server.

[0113] The resource transfer server is a server used to process resource transfer transactions. It acts as a bridge between the resource recipient and the resource output gateway (or bank), ensuring the security, efficiency, and reliability of the entire resource transfer process. The specific process of the resource transfer server performing resource transfer operations is described in the following embodiments.

[0114] In the aforementioned resource transfer method, a first wearable device responds to a resource transfer operation by obtaining plaintext reference information; the first wearable device encrypts the plaintext reference information based on a first public key to obtain ciphertext reference information; the first wearable device sends the ciphertext reference information to a second wearable device, enabling the second wearable device to display the plaintext reference information obtained by decrypting the ciphertext reference information based on a first private key corresponding to the first public key; the first wearable device responds to a resource transfer authorization operation for the plaintext reference information and executes the resource transfer operation according to the plaintext reference information. This process, through the collaboration of a first wearable device with network connectivity and a second wearable device with display capabilities, provides a resource transfer scheme that collaboratively completes resource transfer tasks using different types of wearable devices. On the one hand, the entire process allows for secure resource transfer without requiring the user to activate the mobile terminal, improving the convenience of resource transfer; on the other hand, the entire data transmission process uses ciphertext transmission, thereby ensuring the security of the resource transfer process.

[0115] Based on the technical solutions of the above embodiments, this application also provides an optional embodiment. In this optional embodiment, the above resource transfer method is further described.

[0116] See Figure 3 The first public key acquisition step shown includes:

[0117] S310, a certificate acquisition request is sent to the second wearable device, so that the second wearable device responds to the certificate acquisition request and sends the target certificate to the first wearable device.

[0118] The certificate acquisition request is used to request the second wearable device to send the target certificate to the first wearable device.

[0119] The target certificate can be a certificate used to verify the identity of the second wearable device, i.e., the first certificate mentioned below; or it can be a certificate used to verify the collaborative relationship between the first wearable devices, i.e., the second certificate mentioned below.

[0120] In one optional implementation, the target certificate includes a first certificate. The first certificate is generated as follows: the first wearable device generates a master device key pair; when the first wearable device and the second wearable device connect for the first time, the first wearable device responds to the first certificate application request sent by the second wearable device and sends a key generation instruction to the second wearable device to instruct the second wearable device to generate a corresponding slave device key pair; in response to the key generation instruction, the second wearable device generates a slave device key pair and a random factor corresponding to the second wearable device, and reads the device identification (ID) of the second wearable device; the second wearable device sends the public key (i.e., the third public key, slave device public key, hereinafter referred to as the third public key), the random factor, and the device ID from the slave device key pair to the first wearable device; the first wearable device uses the private key (i.e., the second private key, master device private key, hereinafter referred to as the second private key) from the master device key pair to sign the information sent by the second wearable device, generating the first certificate; the first wearable device sends the first certificate to the second wearable device; the second wearable device securely stores the first certificate.

[0121] In one optional implementation, the target certificate includes a second certificate. The second certificate is generated as follows: the second wearable device initiates a resource transfer application authorization login request to the first wearable device; the first wearable device sends a first certificate acquisition request to the second wearable device; the second wearable device sends the first certificate to the first wearable device; the first wearable device uses the private key in the master device key pair to verify the first certificate to obtain the slave device public key in the first certificate; the first wearable device uses the slave device public key to encrypt the resource transfer application authorization login request and sends the encrypted request to the second wearable device; the second wearable device uses the slave device private key (i.e., the third private key below) to decrypt the encrypted request and generates a random factor and a collaboration key pair; the second wearable device uses the slave device private key to sign the collaboration public key (i.e., the first public key) and the random factor to generate the second certificate, and securely stores the second certificate and the collaboration key pair.

[0122] Optionally, a certificate retrieval request can be sent to the second wearable device, so that the second wearable device simultaneously sends a first certificate and a second certificate to the first wearable device; alternatively, a certificate retrieval request can be sent to the second wearable device, so that the second wearable device sends a first certificate to the first wearable device, and if the first certificate is verified successfully, sends a verification success indication to the second wearable device, so that the second wearable device sends a second certificate to the first wearable device in response to the verification success indication; alternatively, a first certificate retrieval request can be sent to the second wearable device, so that the second wearable device sends a first certificate to the first wearable device, and if the first certificate is verified successfully, sends a second certificate retrieval request to the second wearable device, so that the second wearable device sends a second certificate to the first wearable device in response to the second certificate retrieval request.

[0123] S320 verifies the target certificate to obtain the first public key.

[0124] In one possible implementation, the target certificate includes a first certificate and a second certificate; correspondingly, the first certificate can be verified based on the second private key to obtain a third public key; the first certificate is obtained by signing the third public key based on the second private key; the second certificate is verified based on the third public key to obtain the first public key; the second certificate is obtained by signing the first public key based on the third private key corresponding to the third public key.

[0125] For example, since the first certificate is obtained by signing the third public key with the second private key, after obtaining the first certificate, it can be determined whether the signature information of the first certificate is the second private key. If so, the verification passes and the third public key in the first certificate is obtained. Since the second certificate is obtained by signing the first public key with the third private key, after obtaining the third public key, it can be determined whether the signature information of the second certificate and the third public key are a pair of asymmetric keys. If so, the verification passes.

[0126] In the above embodiments, when the first wearable device and the second wearable device connect for the first time, the first wearable device issues a first certificate to the second wearable device. This facilitates the verification of the second wearable device's identity during subsequent communication or resource transfer scenarios, improving the security of resource transfer. Furthermore, the first wearable device authorizes resource transfer collaboration with the second wearable device. In resource transfer scenarios, after the first certificate verification is successful, the second certificate is verified to confirm the collaboration relationship between the first and second wearable devices, further enhancing the security of resource transfer.

[0127] Based on the technical solutions of the above embodiments, this application also provides an optional embodiment. In this optional embodiment, the process of performing a resource transfer operation in response to a resource transfer authorization operation for plaintext reference information is refined.

[0128] See Figure 4 The resource transfer steps shown include:

[0129] S410, in response to a resource transfer authorization operation for plaintext reference information, sends a resource transfer authorization request to the second wearable device.

[0130] The resource transfer authorization operation can be understood as a confirmation operation to transfer resources. For example, the resource transfer confirmation operation may be a user clicking on the confirmation control corresponding to the plaintext of the first reference information displayed on the second wearable device; the resource transfer confirmation operation may be a scanning operation of the POS machine on the plaintext of the second reference information.

[0131] The resource transfer authorization request is used to request the user to confirm the resource transfer authorization.

[0132] For example, in response to a user's resource transfer authorization operation for plaintext reference information displayed on a second wearable device, the first wearable device sends a resource transfer authorization request to the second wearable device.

[0133] S420 receives authorization confirmation information from the second wearable device in response to the resource transfer authorization request, and performs the resource transfer operation in conjunction with the resource transfer server.

[0134] The authorization confirmation information may include resource transfer passwords, such as digital passwords or biometric passwords (including fingerprints or facial recognition, etc.).

[0135] For example, after receiving the authorization confirmation information from the second wearable device regarding the resource transfer authorization request, the first wearable device sends the authorization confirmation information to the resource transfer server, so that the resource transfer server can perform the resource transfer operation after verifying the authorization confirmation information.

[0136] In some embodiments, to facilitate users' understanding of the resource transfer progress, after the resource transfer server verifies the authorization confirmation information, it will send the resource transfer result back to the first wearable device. The first wearable device will then send the resource transfer result to the second wearable device for the second wearable device to display the resource transfer result.

[0137] In the above embodiments, a resource transfer authorization request is sent to the second wearable device before the resource transfer operation is performed, and the resource transfer operation is only performed in conjunction with the resource transfer server after receiving the authorization confirmation information from the second wearable device for the resource transfer authorization request, which can further improve the security of resource transfer.

[0138] In one exemplary embodiment, such as Figure 5 As shown, a resource transfer method is provided, which can be applied to... Figure 1Taking the second wearable device 104 as an example, the following steps are included:

[0139] S510 receives encrypted reference information.

[0140] The ciphertext of the reference information is obtained by encrypting the plaintext of the reference information acquired in response to the resource transfer operation using the first wearable device based on the first public key. The process of generating the ciphertext of the reference information has been described in the above embodiments and will not be repeated here.

[0141] S520: Decrypt the ciphertext of the reference information based on the first private key corresponding to the first public key to obtain the plaintext of the reference information.

[0143] In one alternative implementation, the first reference information ciphertext can be decrypted based on the first private key to obtain the first reference information plaintext; the first reference information ciphertext is obtained by the first wearable device encrypting the first reference information plaintext based on the first public key; the first reference information plaintext is obtained by the first wearable device parsing the graphic code acquired in response to the image acquisition operation.

On the one hand, the entire process can be completed securely without the user activating the mobile terminal, improving the convenience of resource transfer; on the other hand, the entire process uses encrypted transmission during data transmission, thereby ensuring the security of the resource transfer process.
