Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides a block chain-based voice transmission method, including:
s101, determining a blockchain platform which is created in advance based on a blockchain framework, wherein nodes in the blockchain platform comprise a voice sender and a voice receiver.
The Blockchain (Blockchain) is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like, and is essentially a decentralized database.
A blockchain platform created based on the blockchain framework may first be determined. The blockchain frame may be any blockchain frame capable of implementing the corresponding function of the embodiment of the present application, for example, bitcoin, etherhouse, Fabric, Corda, and the like. A blockchain platform may refer to a platform that stores a blockchain, e.g., may be a distributed system, etc. Of course, the blockchain platform may also directly represent the blockchain itself, and is not limited herein.
In the voice transmission process, a voice sender and a voice receiver exist, so that the voice sender and the voice receiver can be deployed in a block chain platform as nodes. Of course, the voice transmission and the voice reception herein refer to a node corresponding to a certain voice, and the node corresponding to a different voice is different, and is not limited herein.
And S102, receiving the voice information sent by the voice sender.
S103, adding the voice information to the digital signature of the voice sender, encrypting the voice information by the public key of the voice receiver, and writing the encrypted voice information into the block chain platform to enable the voice receiver to obtain the voice information.
When a voice sender wants to send voice, corresponding voice information can be sent to the blockchain platform. After receiving the voice information sent by the voice sender, the blockchain platform can write the voice information into the blockchain platform, and the voice receiver can obtain the voice information from the blockchain platform. The voice information at least comprises receiving party information and voice.
Of course, if the voice information is directly written into the blockchain platform, the voice information may be leaked, and other nodes may also acquire the voice information. Therefore, after the voice information is encrypted by the public key of the voice receiver, the voice information is written into the block chain platform, at the moment, the voice receiver can decrypt the voice information by the private key of the voice receiver, and other nodes cannot acquire the voice information. In addition, when the voice information is sent, the digital signature of the voice sender can be added, the identity of the voice sender can be proved, and the safety of the voice information is further improved.
In one embodiment, the voice receiver is not able to hear voice on all occasions, and the voice information is stored in the blockchain platform and is inconvenient to find. Therefore, after the voice information is received, the voice information can be converted into the text information, and then the text information and the voice information are written into the block chain platform at the same time. When receiving the voice information, the voice receiver can simultaneously acquire the corresponding text information, and can also learn the corresponding text information even if the voice receiver is inconvenient to listen to at present. And in the subsequent retrieval, the voice does not need to be listened again, so that the method is very convenient.
Specifically, the conversion model may be trained in advance, and then the voice information is input into the conversion model, so as to obtain the corresponding text information. When the conversion model is trained, a plurality of voice messages can be collected in advance to serve as training samples, and the conversion model is obtained through supervised training. When training the conversion model, the conversion model may be implemented by a Convolutional Neural Network (CNN), a decision tree, or other manners, which are not limited herein.
In the case of converting text information, usually, the converted text information is all in a language corresponding to speech information. For example, if the speech is Chinese, the converted text message will also be Chinese. However, in this case, if the voice receiving side is not proficient in the language, it is inconvenient to receive the information. Therefore, before the text information is converted, the corresponding native language can be determined according to the pre-collected identity information of the voice receiver. For example, if the nationality of the voice recipient is china in the identity information of the voice recipient, the native language is chinese. If the nationality is the United states, its native language is English. After the text information is converted, if the language corresponding to the text information is different from the native language corresponding to the voice receiving party, the text information can be converted into the text information corresponding to the native language, so that the voice receiving party can conveniently obtain the information.
In one embodiment, after receiving the voice message, the duration of the voice message may be determined. If the duration is too long and exceeds the preset duration, the voice receiver is very inconvenient to listen to the voice. Once a word is not listened to, the user needs to listen to the voice again, and the user experience is reduced. At this time, the voice information can be divided into a plurality of sub-voice information, then digital signatures are respectively added, and the sub-voice information is encrypted by a public key of a voice receiver and then written into the block chain platform. When the voice information is divided into molecules, the molecules can be equally divided according to the time length, or the molecules can be divided into one segment when the certain time length is reached.
In one embodiment, the corresponding intelligent contracts may also be generated in advance and deployed in the blockchain platform. The intelligent contract comprises voice information, digital signature and public key. The intelligent contract is used for adding the digital signature to the voice information after receiving the voice information, and writing the voice information into the block chain platform after encrypting the voice information through the public key of the voice receiver. Since the intelligent contracts on the blockchain platform are public, each node can check whether the intelligent contracts are in accordance with the preset agreement or not and deploy the intelligent contracts on the own node. And each node can inquire the intelligent contract through a corresponding way, so that the degree of automation of the transaction is improved, and the trust degree of each node is further increased. The intelligent contract can only be changed in an upgrading mode, each node needs to be synchronously deployed, once the intelligent contract is deployed, the intelligent contract can only be executed through a program, interference of human factors is avoided, and the reliability of data is enhanced.
In one embodiment, a digital object Unique Identifier (DOI) for the voice information may also be generated, for example, a two-dimensional code, a barcode, etc., so that the voice receiver can more conveniently query the voice information. Taking the two-dimensional code as an example, the voice receiver can access the data associated with the voice information by scanning the two-dimensional code corresponding to the voice information.
As shown in fig. 2, an embodiment of the present application further provides a voice sending device based on a block chain, including:
at least one processor; and the number of the first and second groups,
a memory communicatively coupled to the at least one processor; wherein the content of the first and second substances,
