detailed description

In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present specification, the technical solutions in the embodiments of the present specification will be described in detail in conjunction with the drawings in the embodiments of the present specification. Obviously, the described implementation Examples are only a part of the embodiments of this specification, but not all the embodiments. Based on the embodiments in this specification, all other embodiments obtained by those of ordinary skill in the art should fall within the scope of protection.

The technical solutions provided by the embodiments of this specification will be described in detail below in conjunction with the drawings. As shown in FIG. 1, FIG. 1 is a schematic flowchart of a method for confirming a photographic image provided by an embodiment of the present specification. The process specifically includes the following steps:

S101: When it is monitored that the user inputs a photography confirmation instruction, acquire the biological characteristics of the user.

The user is the original author of the photographic work involved in the embodiment of the specification. The user's biometrics may include fingerprints, facial features, irises, etc. The above biometrics are usually unique and can be used to represent the user's identity. The user's biometrics can be saved or transmitted in the form of a file in a certain format.

At present, when a user takes a picture, it can be done through an electronic device carrying an electronic camera (for example, a mobile phone, a personal computer, or other devices, etc.), or through a photography device with an optical camera. It should be noted that the electronic device or photographing device is generally a device with a biometrics collection function and a communication function.

For example, when a user takes a picture through a mobile phone, he can press a designated sensor module on the mobile phone to send a photograph confirmation instruction. Therefore, by integrating the fingerprint collection function on the sensing module in advance, whenever the user sends a photograph confirmation instruction, the fingerprint of the user's finger acting on the mobile phone at this time can be collected immediately.

For another example, when the user shoots through the photographing device of the optical camera, in this photographing mode, the eyes of the user's face are usually required to be close to the device to observe to perform operations such as adjusting the focal length and light sensitivity. Therefore, a dedicated facial feature collection module or an iris feature collection module may be preset in the photographing device, and whenever the user presses the shutter, the corresponding facial feature or iris feature at this time is correspondingly acquired.

In addition, in this way, the user needs to confirm photography by pressing the shutter. At this time, the action that the user presses the shutter means that the user sends a photography confirmation instruction, so the fingerprint collection function can also be integrated on the shutter, and whenever the user presses the shutter, the fingerprint of the finger pressing the shutter at this time is obtained.

After the user device obtains the user's biological characteristics, it is equivalent to collecting the identity information of the original author, which can be used as evidence for confirming the right of the photographic picture.

S103: Determine a photographic picture corresponding to the photographing confirmation instruction.

S105, construct a target transaction based on the photographic picture and the user's biometrics, and broadcast the target transaction to the right confirmation blockchain network, so that each node in the right confirmation blockchain network is based on a consensus mechanism Perform consensus processing on the target transaction, and publish the target transaction to the confirmation blockchain after the consensus is passed.

When the user equipment is a node of the right-of-charge blockchain, the user equipment can locally bind the two to construct a target transaction after acquiring the user's biological characteristics and photographic pictures.

If the user device is not a node of the confirmation blockchain, it can send the acquired user's biological characteristics and photographic pictures to the node of the confirmation blockchain, so that the node can construct the target transaction. As shown in FIG. 2, FIG. 2 is a schematic diagram of a system for confirming rights based on blockchain photography images provided by an embodiment of the present specification. The hollow points in the figure are the non-consensus node devices in the alliance chain, and the solid points are the consensus node devices in the alliance chain. When confirming that the blockchain is a consortium chain, usually, the nodes can be server devices, and only certain predetermined nodes can perform consensus. The user equipment can directly send the obtained user's biometrics and photographs to any consensus or non-consensus node (that is, sent to the server) of the above-mentioned alliance chain, and the node (server) will construct the transaction and initiate consensus, thereby There is no need to construct transactions locally on user equipment, which is more convenient and saves user time. When the user needs to confirm the query, he can query through the relevant interface of the confirmation blockchain.

In the above method of constructing a target transaction through the server, the corresponding client can be pre-installed on the user device, and the user can obtain the photographic pictures and biological characteristics corresponding to the photography confirmation instruction through the client and send it to the server, which can guarantee The obtained photographs and biometrics are true and reliable. The client and server can be transmitted in a manner similar to the HyperSocket Text Transfer Protocol (HyperText TransferProtocol over Secure Socket Layer, HTTPS) to ensure that No information leakage will occur during transmission.

The transfer described in this specification refers to a piece of data created by the user through the client of the confirmation blockchain and needs to be finally released to the distributed database of the confirmation blockchain.

Among them, there are transactions in the narrow sense and transactions in the broad sense in the blockchain. The narrow sense of the transaction refers to a value transfer issued by the user to the blockchain; for example, in the traditional Bitcoin blockchain network, the transaction can be a transfer initiated by the user in the blockchain. The generalized transaction refers to a piece of business data with business intent published by the user to the blockchain; for example, the operator can build an alliance chain based on actual business needs, relying on the alliance chain to deploy some other types that have nothing to do with value transfer Online business (for example, rental business, vehicle scheduling business, insurance claims business, credit service, medical service, etc.), and in this type of alliance chain, the transaction can be a business with business intent issued by the user in the alliance chain Message or business request.

After the user equipment obtains the photographic picture and the user's biological characteristics, it also collects evidence to confirm that the user is the original author of the photographic picture. At this time, the user equipment may be based on the photographic picture and the user's biological characteristics Build a target transaction and broadcast the target transaction to the right-of-trust blockchain network, so that each node in the blockchain network will publish the target transaction to the right-of-trust blockchain based on a consensus mechanism. Because the user's biological characteristics and photographic pictures are bundled for blockchain certification, it is difficult to be tampered with, so it can be used as evidence that the user is the original author of the photographic work.

In the embodiment of the present specification, the manner in which the user equipment or the server constructs a target transaction based on the photographic picture and the user's biometrics may be to construct a target transaction that includes the photographic picture and the user's biometrics. In this case, the photographic picture and the user's biological characteristics themselves will be stored in the blockchain, which has high requirements on the storage capacity of the nodes in the blockchain network.

Further, the server can also perform instant matching based on the user's biological characteristics to obtain the user's identity information, which can be such as an ID number, a driver's license number, or an email account. For example, the user registers his biometrics and identity information with the server in advance, and when executing the solution provided by the embodiments of the present application, the user equipment sends the user's biometrics to the server, and the server identifies the biometrics And return the user's identity information. Then, the user equipment determines the identity information of the user according to the biological characteristics of the user, and constructs a target transaction including the photographic picture and the identity information of the user. Alternatively, when the server is a node of the right-of-charge blockchain, the identity information can be directly identified on the server, and a target transaction including the photographic picture and the user's identity information can be constructed.

Of course, when constructing the target transaction, the server may also include the user's identity information and biometrics at the same time, and construct a target transaction that includes the photographic image, the user's identity information, and biometrics.

In addition, when the server is a node of the right-of-charge blockchain, it can also obtain more information for assisting identification based on the user's biological characteristics, such as the user's mobile phone number, name, and so on. In this embodiment, the target transaction constructed by the server may also include the above-mentioned information for assisting identification. As shown in FIG. 3, FIG. 3 is a schematic diagram of a method for a server to construct a target transaction provided by an embodiment of the present specification.

In an embodiment, when the user equipment or the server builds a target transaction based on the photographic picture and the user's biometrics, a hash algorithm may be used for the photographic picture and the user's biometrics to determine A target hash corresponding to the photographic picture and the user's biological characteristics and/or identity information, and then construct a target transaction containing the target hash. The target hash is actually a string of characters and takes up very little storage space. Storing the target hash in the blockchain does not require high storage capacity for the nodes in the blockchain network. In addition, since whether the photographic picture and the user's biometrics are modified can be detected by the target hash, storing the target hash in the blockchain is also equivalent to realizing the The original author has carried out multi-party certificate deposit.

In addition, before constructing the target transaction, the user equipment or the server can also obtain the user's location and time information at the time of shooting through the user equipment. For example, when shooting with a mobile phone, the user can obtain the current location of the user through the positioning module on the mobile phone and the current system time through the time module. Therefore, at the same time when the photography confirmation instruction is received, the user’s current location and current time can be used as the generation time stamp and generation location information of the photography picture, and the above generation time and/or generation can be added when constructing the target transaction The location information further helps to confirm the power.

Each node in the confirmation blockchain network performs consensus processing on the target transaction based on a consensus mechanism, and after the consensus is passed, the target transaction is posted to the confirmation blockchain, and a confirmation hash can be returned at this time. To the user, the user can query the confirmation blockchain through the confirmation hash to confirm the original identity.

Correspondingly, the embodiment of the present specification also provides a blockchain-based photographic picture confirmation device, as shown in FIG. 4, FIG. 4 is a blockchain-based photographic picture confirmation device provided by the embodiment of the specification Schematic structure, including:

The obtaining module 401, when it is detected that the user inputs a photography confirmation instruction, obtains the user's biological characteristics;

The determining module 403 determines the photographic picture corresponding to the photographing confirmation instruction;

Construct a transaction module 405, construct a target transaction based on the photographic picture and the user's biometrics, and broadcast the target transaction to the right confirmation blockchain network, so that each node in the right confirmation blockchain network Consensus process the target transaction based on a consensus mechanism, and publish the target transaction to the blockchain after the consensus is passed.

Further, the obtaining module 401 obtains at least one of fingerprint characteristics, iris characteristics or facial characteristics of the user.

Further, the construction transaction module 405 constructs a target transaction including the photographic picture and the user's biometrics; or, determines the user's identity information according to the user's biological features and constructs the photographic picture Target transactions with the user's identity information.

Further, the construction transaction module 405 uses a hash algorithm for the photographic picture and the user's biometrics to determine the target hash corresponding to the photographic picture and the user's biological characteristics; Describe the target transaction of the target hash.

Further, the construction transaction module 405 determines the generation time stamp and/or generation location information of the photographic picture; based on the photography picture, the user's biological characteristics and the generation time stamp and/or generation location information Construct target transactions.

Further, the construction transaction module 405 locally constructs a target transaction based on the photographic picture and the user's biometrics; or, sends the photographic picture and the user's biometrics to the blockchain network's Nodes so that the nodes construct target transactions.
