The functions that can be implemented by each device in the application scenario shown in fig. 1 will be described together in the following method embodiments, which are not described in detail herein.

The flow of the data processing method provided in the embodiments of the present application may be executed by the resource transfer server 102 or the resource transfer terminal device 101 in fig. 1, or may be executed by both the resource transfer server 102 and the resource transfer terminal device 101, and the description is mainly given here by taking the resource transfer terminal device 101 as an example.

Referring to fig. 4, a flow chart of a data processing method provided in an embodiment of the present application is shown, the flow chart is applied to an electronic device, where the electronic device may be a terminal device or a server that initiates an object, and the specific flow chart is as follows:

S401, responding to a palmprint registration operation triggered by an initiating object, and acquiring a first palmprint image of the initiating object.

Taking electronic resource transfer as an example, particularly a palm-brushing payment technology in electronic payment technology, it refers to a mechanism that can complete identity confirmation and payment of a payment object by scanning a palm.

When the user registers to open the palm-brushing payment service, the electronic device may collect a palm print image of the user through the camera, and the palm print image may be red-green-blue (RGB) three-color image data or (Infrared, IR) image data, but is not limited thereto.

In the embodiment of the application, an object initiating the fusion of the palm print images is called an initiating object, an object participating in the fusion of the palm print images is called an object to be shared, the palm print images stored after successful registration are called reference images, the first palm print image is the reference image of the initiating object, and the second palm print image is the reference image of the object to be shared. The object may be a user or an account, but is not limited thereto, and is described herein by way of example only.

In order to ensure that a unique tamper-proof NFT is generated, when palm print registration is performed, the palm print image to be registered can be subjected to uniqueness verification by determining that the palm print image to be registered belongs to an unregistered palm print image. Referring to fig. 5, in performing S401, the following steps may be employed, but are not limited to:

S4011, responding to a palmprint registration operation triggered by an initiating object, and acquiring a palmprint image to be detected, which is input by the initiating object. The palm print image to be detected, which is input by the initiating object, refers to the collected palm print image to be registered.

S4012, when it is determined that the palm print image to be detected does not exist in the reference palm print images, the palm print image to be detected is used as a first palm print image of the initiating object.

Specifically, when it is determined that the palm print image to be detected does not exist in each reference palm print image, the following manner may be adopted, but is not limited to:

Extracting features of the palm print image to be detected to obtain first palm print features corresponding to the palm print image to be detected; and acquiring second palm print characteristics corresponding to each reference palm print image, and determining that the palm print image to be detected does not exist in each reference palm print image when the similarity between the first palm print characteristics and each second palm print characteristics is determined to be smaller than a preset similarity threshold value.

The feature extraction is performed on the palm print image to be detected, and when the first palm print feature corresponding to the palm print image to be detected is obtained, a machine learning model for feature extraction can be used for implementation, but not limited to, and the machine learning model can be used for implementation of a deep learning model.

The electronic device performs image segmentation, normalization processing and feature extraction on the palm print image to be detected through the deep learning model for feature extraction to obtain a 512-dimensional feature vector, wherein the feature vector is the first palm print feature corresponding to the palm print image to be detected. Similarly, the same deep learning model can be used to extract the features of each reference palmprint, so as to obtain the second palmprint features corresponding to each reference palmprint. Different palm print features can be obtained for different palm print images through a machine learning model, and can be used for representing different biological features.

The second palm print features corresponding to each reference palm print may be generated in advance, or may be generated after feature extraction is performed on the palm print image to be detected, so as to obtain the first palm print features corresponding to the palm print image to be detected, which is not limited.

The similarity between the first palm print feature and each second palm print feature may be cosine similarity, but is not limited thereto, and the embodiment of the application is only described by taking cosine similarity as an example. The cosine similarity is proportional to the similarity, and the higher the cosine similarity of the two palmprint features is, the more similar the two palmprint features are.

For example, referring to fig. 6, a to-be-detected palm print image input by the account a is obtained, and feature extraction is performed on the to-be-detected palm print image to obtain a first palm print feature corresponding to the to-be-detected palm print image, and if the reference palm print image includes reference palm print images 1 and … … and reference palm print image m, a second palm print feature corresponding to each reference palm print image is obtained, a similarity threshold is 0.9, then cosine similarity between the first palm print feature and each second palm print feature is calculated, the cosine similarity between the first palm print feature and each second palm print feature is 0.1, … … and 0.2, and each cosine similarity is not more than 0.9, and it is determined that the to-be-detected palm print image does not exist in each reference palm print.

Through the implementation mode, the similarity between the two palmprint images is evaluated by adopting palmprint characteristics, and the efficiency and accuracy of similarity comparison are improved, so that repeated registration of the same palmprint image is avoided, and the palmprint registration efficiency is improved.

In one implementation, to improve data processing efficiency, after the reference palm print image is generated, the reference palm print image may be stored in an image library, and palm print features corresponding to the reference palm print image are stored in a feature library, where, illustratively, the storing component tableKV is used for performing persistent storage of the palm print features, and the storing component WeChat distributed file system (WECHAT FILE SYSTEM, WFS) is used for performing persistent storage of the palm print image, but not limited thereto.

In one implementation, referring to fig. 7, considering that if all the palm print features are stored in one feature library, the access pressure of the feature library is too high, a full feature library and a plurality of local feature libraries are set, wherein the full feature library stores all the palm print features of the reference palm print image, and the local feature library stores the palm print features of part of the reference palm print image. The local features may be set according to geographic locations, for example, 3 local feature libraries are set, where the 3 local feature libraries are local databases located in city a, city B, and city C, respectively.

The palm print features of each user's palm print image may also be stored in a terminal device or server, and the database in the terminal device for storage may be referred to as a local feature library.

The palm print characteristics of the palm print image of each user can be stored in the memory of the terminal equipment or the server, and when any one of the local characteristic library and the full characteristic library is subjected to data change, the changed data are synchronously updated into the memory in an incremental synchronous mode. And after the first palm print characteristics of the palm print image to be detected are obtained, the second palm print characteristics of each reference palm print image can be obtained from the memory, and then characteristic retrieval is carried out based on the first palm print characteristics and the second palm print characteristics, so that whether the palm print image to be detected is a registered palm print image or not is determined. In addition, in the embodiment of the application, each palmprint feature stored in the memory can also be used for feature retrieval, feature management, feature issuing and the like. The stored palmprint features may also be used for, but are not limited to, site lighting management, base map management, model training, and the like.

S402, responding to a sharing operation triggered by an initiating object aiming at least one object to be shared, and acquiring respective second palmprint images of the at least one object to be shared when the palmprint fusion authorization of the at least one object to be shared is determined to be acquired.

The object to be shared may be other objects in the electronic resource transfer application than the initiating object, but is not limited thereto. For example, the initiating object and the object to be shared are both users in the palm payment application.

As a possible implementation manner, a registration success interface is presented to the initiating object, the registration success interface comprises a fusion control, an object selection interface is presented to the initiating object in response to a triggering operation of the initiating object for the fusion control, and when the initiating object selects at least one object to be shared in all candidate objects contained in the object selection interface, the initiating object is determined to trigger a sharing operation for the at least one object to be shared.

One candidate object may be an object or a group formed by a plurality of objects, and if the candidate object selected by the initiating object is a group, the other objects except the initiating object in the group are taken as the objects to be shared.

For example, referring to fig. 8, the registration success interface includes a prompt message "the palm payment service has been opened", a "multi-user NFT" button, which is a fusion control, and an authorization component, where the text information of the authorization component is "authorized to use the palm print image", and when the user clicks the authorization component, it is indicated that the user gives permission to use the palm print image. The user A clicks the authorization component and clicks a multi-user NFT button, and an object selection interface is presented for the user A in response to the triggering operation of the user A on the fusion control by the initiating object, wherein the object selection interface comprises candidate objects: user B, group 1, group 2, etc., wherein group 1 includes user a, user B, user D, and user E, group 2 includes user a, user B, user D, and user E, and the object selection interface further includes a "share" button, and when user a selects at least one candidate object and clicks the "share" button, it is explained that user a selects the at least one candidate object, and supposing that user a selects "group 1" from among the candidate objects included in the object selection interface and clicks the "share" button, it is explained that user a selects group 1 from among the candidate objects included in the object selection interface, and it is ascertained that user a triggers a sharing operation with respect to user B and user C.

As another possible implementation, the user may also trigger a sharing operation in the group chat interface. Specifically, if the initiating object and the at least one object to be shared are located in the same group, when the initiating object triggers the fusion control in the group chat interface, it is determined that the initiating object triggers the sharing operation for the at least one object to be shared, where the at least one object to be shared may be at least one other object except the initiating object in the group, and the at least one other object may be specified by the initiating object, or may be all other objects except the initiating object in the group, which is not limited.

Specifically, when S402 is executed, in response to a sharing operation triggered by an initiating object for at least one object to be shared, a fusion authorization message is sent in a group, when an authorization notification of each of the at least one object to be shared is received within a set duration, it is determined that a palmprint fusion authorization of the at least one object to be shared is obtained, and a second palmprint image of each of the at least one object to be shared is obtained.

It should be noted that, if the object to be shared performs palm print registration, the terminal device corresponding to the object to be shared may directly obtain the palm print fusion authorization operation input by the object to be shared in the corresponding operation interface, if the object to be shared performs palm print registration, the terminal device corresponding to the object to be shared may register the image palm print image of the object to be shared after obtaining the palm print fusion authorization operation input by the object to be shared in the corresponding operation interface, and the palm print image registration process of the object to be shared refers to the palm print image registration process of the initiating object, which is not described herein.

For example, referring to fig. 9, the group 1 includes a user a, a user B, and a user C, the user a clicks a fusion control "multi-user NFT" button in the group chat interface, and in response to a trigger operation of the user a on the fusion control "multi-user NFT" button in the group chat interface, a fusion authorization message is sent in the group 1, and if a set duration is 10 minutes, when authorization notifications of the user B and the user C are received within 10 minutes, it is determined that palm print fusion authorizations of the user B and the user C are acquired, and second palm print images of the user B and the user C are acquired.

Through the implementation mode, the waiting time length can be controlled by setting the time length, the use feeling of the object is improved, and meanwhile, when fusion authorization of each object to be shared is obtained, corresponding palmprint images are obtained, so that the privacy of the object is ensured, and the safety of object information is improved.

S403, fusing the first palm print image and the acquired at least one second palm print image based on the respective image fusion sequence of the initiating object and the at least one object to be shared, and obtaining respective fusion images of the initiating object and the at least one object to be shared.

And S403, fusing the first palm print image and the acquired at least one second palm print image based on the image fusion sequence corresponding to the initiating object to obtain a fused image of the initiating object, and fusing the first palm print image and the acquired at least one second palm print image based on the image fusion sequence corresponding to the at least one object to be shared to obtain the fused image of the at least one object to be shared.

Since the generating process of the fusion image of the initiating object is the same as that of the fusion image of the object to be shared, the generating process of the fusion image of the initiating object will be described below as an example.

As a possible implementation manner, when the first palm print image and the acquired at least one second palm print image are fused, the first palm print image and the acquired at least one second palm print image may be directly spliced according to an image fusion sequence corresponding to the initiating object.

For example, referring to fig. 10, the image fusion sequence of the user a is that of the user a, the user B, and the user C, the first palm print image of the user a is the image 1, the second palm print image of the user B is the image 2, the second palm print image of the user C is the image 3, and the images 1, 2, and 3 are spliced according to the sequence of the user a, the user B, and the user C to obtain the fusion image a of the user a. The image fusion sequence of the user B is user A, user B and user C, and the image 1, the image 2 and the image 3 are spliced according to the sequence of the user B, the user A and the user C to obtain a fusion image B of the user B. The image fusion sequence of the user C is that of the user C, the user A and the user B, and the image 1, the image 2 and the image 3 are spliced according to the sequence of the user C, the user A and the user B to obtain a fusion image C of the user C.

As another possible implementation manner, in order to improve flexibility of palm print image fusion, operation interestingness of the object is increased so as to improve use feeling of the object, a first palm print image may be presented to the initiating object, an edited first palm print image is obtained in response to an image editing operation triggered by the initiating object for the first palm print image, and the edited first palm print image and the obtained at least one second palm print image are spliced to obtain a fused image of the initiating object. The image editing operation includes, but is not limited to, adding text, graffiti, watermark and the like.

For example, the initiating object may add a flower decorative image to the first palm print image, and splice the first palm print image after adding the flower decorative image and the acquired at least one second palm print image to obtain a fused image of the initiating object.

In the embodiment of the present application, one or more objects in each object to be shared may edit the respective second palm print image, and further splice the edited first palm print image and the edited at least one second palm print image to obtain a fused image of the initiating object.

As an example, the initiating object edits the first palm print image, and then the first palm print image and the acquired at least one second palm print image are spliced to obtain a fused image of the initiating object. As a second example, the initiating object edits the first palm print image, and each object to be shared edits the respective second palm print image, and then the edited first palm print image and the edited at least one second palm print image are spliced to obtain a fusion image of the initiating object. As a third example, each object to be shared edits the respective second palm print image, and then the first palm print image and at least one edited second palm print image are spliced to obtain a fusion image of the initiating object. The above description only uses the editing of the respective second palm print image by each object to be shared as an example, and the editing of the respective second palm print image by the partial objects in each object to be shared may also be performed, and the process is similar and will not be repeated here.

In some embodiments, the respective image fusion order of the initiating object and the at least one object to be shared is obtained by:

firstly, obtaining an initial fusion sequence between an initiating object and at least one object to be shared;

Secondly, aiming at the initiating object and at least one object to be shared, the following operations are respectively executed:

And when the position of the target object in the initial fusion sequence is determined to be not the set position, adjusting the target object to the set position, and taking the adjusted initial fusion sequence as the image fusion sequence of the target object.

If the position of the target object in the initial fusion sequence is the set position, the initial fusion sequence may be directly used as the image fusion sequence of the target object.

For example, if the initial fusion order is user a, user B, and user C, the set position is the first in the initial fusion order, and the target object is user a, the position of user a in the initial fusion order is the set position, and the initial fusion order is directly used as the image fusion order of user a, that is, the image fusion order is user a, user B, and user C.

For another example, if the initial fusion order is user a, user B, and user C, the set position is the first in the initial fusion order, and the target object is user B, then the position of user B in the initial fusion order is not the set position, user B is adjusted to the set position, and the adjusted initial fusion order is taken as the image fusion order of user B, and the image fusion order is user B, user a, and user C.

Through the implementation manner, the target object is adjusted to the set position, so that the generated fusion images are different, different objects can generate the NFT with the same content and different sequences, and the problem that the NFT can only hold one copy is solved.

In some embodiments, the initial fusion order between the initiating object and the at least one object to be shared may be obtained in at least one of, but not limited to:

In the first mode, based on respective fusion authorization time of at least one object to be shared, an initial fusion sequence between an initiating object and at least one object to be shared is obtained.

The fusion authorization time may refer to a time when the electronic device receives the fusion authorization returned by the at least one object to be shared. Specifically, at least one object to be shared can be sequenced according to the sequence from the morning to the evening based on each fusion authorization time, a sequencing result is obtained, an initiating object is taken as a first object, and an initial fusion sequence between the initiating object and the at least one object to be shared is obtained by combining the sequencing result.

For example, the initiating object is a user a, the object to be shared includes a user B and a user C, where the fusion authorization time of the user B is 10:05 and the fusion authorization time of the user C is 10:06, so that, based on the fusion authorization times, the user B and the user C are ordered according to the order from the early to the late to obtain an ordering result, the ordering result characterizes that the order of the user B is before the order of the user C, the user a is taken as a first object, and the ordering result is combined to obtain an initial fusion order among the user a, the user B and the user C, where each object in the initial fusion order is sequentially: user a, user B, user C.

Through the implementation manner, the initial fusion sequence can be obtained quickly, and the NFT generation efficiency is improved.

In a second possible implementation manner, in order to implement NFT generation personalized for the user, in an embodiment of the present application, the initial fusion order may also be specified by the user. Specifically, in response to input operations triggered by the initiating object and the at least one object to be shared, an initial fusion sequence of the respective inputs of the initiating object and the at least one object to be shared is obtained.

Taking the object x as an example, the object x may be any one of an initiating object and at least one object to be shared. Specifically, the electronic device may present an object list including an initiating object and at least one object to be shared to the object x in the operation interface, where the object x may adjust an order between the initiating object and the at least one object to be shared in the operation interface, and further the electronic device obtains an initial fusion order input by the object x in response to an input operation of the object x with respect to the initial fusion order.

For example, taking the object x as the user a as an initiating object, the electronic device may present an object list including the user a, the user B, and the user C to the user a in an operation interface, where the user a adjusts an order among the user a, the user B, and the user C in the operation interface, and the electronic device obtains an initial fusion order input by the user a in response to an input operation of the user a with respect to the initial fusion order, where each object in the initial fusion order is sequentially: user a, user C, user B.

For another example, taking the object x as the user B, the user B as the object to be shared, the electronic device may present the object list including the user a, the user B, and the user C to the user B in the operation interface, the user B adjusts the order among the user a, the user B, and the user C in the operation interface, and the electronic device obtains the initial fusion order input by the user B in response to the input operation of the user B with respect to the initial fusion order, where each object in the initial fusion order is sequentially: user C, user a, user B.

S404, based on the obtained fusion images, obtaining NFT of each of the initiating object and the at least one object to be shared.

NFT is a trusted digital rights voucher with unique characteristics in a blockchain network, which is a data object that can record and process multidimensional, complex attributes on a blockchain.

In the embodiment of the application, the palm print image is used as metadata to generate the NFT of the palm print image, specifically, when S204 is executed, the NFT of the initiating object is obtained based on each obtained fusion image, and at least one NFT of each object to be shared is obtained based on each obtained fusion image. Since the NFT generation process of the initiating object is the same as the NFT generation process of the object to be shared, only the NFT generation process of the initiating object will be described below as an example.

Illustratively, when the NFT of the initiating object is obtained based on the fused image of the initiating object, the following manner may be adopted, but is not limited to:

acquiring image attribute information of a fusion image of an initiating object, and adding the image attribute information into an intelligent contract;

Deploying the intelligent contracts to all nodes in the target blockchain, so that all nodes generate an NFT (network File System) by executing the intelligent contracts, and returning a storage address of the NFT and an NFT private key, wherein the NFT private key is used for representing that an initiating object holds the NFT;

and receiving the storage address and the NFT private key of the NFT returned by any node in the target block chain, and obtaining the NFT of the initiating object based on the storage address and the NFT private key of the NFT.

Wherein the image attribute information may also be referred to as metadata information, at least one of the following attributes in the image attribute information: width, height, resolution, color representation, but are not limited thereto. The NFT private key is held by the NFT owner.

In one embodiment, a corresponding blockchain encryption wallet may be created for a user to record NFT private keys held by the user.

To promote data security, in some embodiments, the blockchain may employ an enterprise blockchain that allows only accounts of the enterprise to be accessed and reviewed. It should be noted that, in the embodiment of the present application, a specific generation process of the NFT in the blockchain is not limited.

In one embodiment, the smart contract may be created based on the ERC-721 protocol and the palm print image may be deposited in the metadata extension IERC721metadata. Sol file based on the ERC721 protocol.

In one embodiment, after the intelligent contract is deployed and uplink, each node in the blockchain may obtain contract information of the intelligent contract, where the contract information includes, but is not limited to, contract identification, contract address, contract issuer, contract issue time, etc., so as to execute the intelligent contract and return the private key of the NFT.

In one embodiment, ownership of the NFT is managed by NFT identification (e.g., NFT ID) and metadata, which other tokens (token) cannot replicate and forge. Thus, NFT IDs and metadata may also be added to the smart contract.

In one embodiment, in order to ensure that the block of the intelligent contract uplink is correct and that the wallet corresponding to the NFT private key is correct, each node returns the storage address of the NFT and the NFT private key when determining that the storage address of the NFT is correct and that the NFT ID does not exist in each stored NFT ID.

In some embodiments, an NFT corresponding to a first palm print image of an initiating object may also be generated based on the first palm print image. The NFT may also be respectively corresponding based on the second palmprint image of each object to be shared.
