Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 is a flowchart illustrating a method for generating a blockchain key based on a biometric result according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step S100, acquiring the biological characteristics and/or behavior characteristics of the user.
In the existing blockchain network, the user identity is mainly authenticated by using a blockchain key, and the blockchain key is generally generated by using a random number or a mnemonic word as a key seed, but since the random number, the mnemonic word and the blockchain key are all foreign objects, once the information is stolen by others, the user identity may be spoofed by others, so that the digital assets of the user are lost. To solve this problem, the present invention utilizes the inherent features that a user has to generate a blockchain key.
In particular, human beings have inherent biological characteristics and behavior characteristics, which are generally unique and difficult to forge and steal, and have the advantages of being "carried around" and readily available, so that the user's biological characteristics or behavior characteristics can be used to generate the blockchain key in the present invention, and the user's biological characteristics and behavior characteristics can also be used to generate the blockchain key. Wherein the biometric characteristic may comprise one or more of the following characteristics: fingerprint features, hand features, face features, iris features, retinal features, genetic features, and pulse features; the behavioral characteristics may include: voice features and/or signature features, etc. The person skilled in the art may set the biological and/or behavioral characteristics according to actual needs, and is not limited herein. Specifically, for a certain feature, a corresponding feature acquisition device may be used for acquisition, and then the acquired feature is acquired in step S100. Taking biological characteristics as fingerprint characteristics, the fingerprint may be collected by a fingerprint collector.
Step S101, identifying the acquired biological characteristics and/or behavior characteristics to obtain at least one biological identification result.
The acquired biological characteristics and/or behavior characteristics can be identified by using a preset identification method, so that at least one corresponding biological identification result is obtained. In particular, the at least one biometric identification result may comprise one or more of the following identification results: fingerprint recognition results, hand shape recognition results, face recognition results, voice print recognition results, iris recognition results, retina recognition results, gene recognition results, vein recognition results, and signature recognition results. The preset identification method and the at least one biometric identification result can be set by those skilled in the art according to actual needs, and are not specifically limited herein. For example, if the acquired biometric features are fingerprint features, the fingerprint features may be identified by using a fingerprint identification method in step S101 to obtain a fingerprint identification result; if the acquired biometric features are iris features, in step S101, iris features may be identified by using an iris identification method to obtain an iris identification result.
And S102, taking at least one biological identification result as a key seed, calculating the key seed by using a preset algorithm, and generating a block chain key for use in transaction.
And after the at least one biological identification result is obtained, taking the at least one biological identification result as a key seed, then calculating the key seed by using a preset algorithm, and taking the calculation result as a block chain key. The user may use the generated blockchain key to conduct a transaction, such as for receiving transaction revenue or paying for a transaction expenditure. The skilled person can select the preset algorithm according to the actual requirement, and the preset algorithm is not limited in detail here. Specifically, the preset algorithm may be a hash algorithm, such as SSHA256 algorithm. The hash algorithm is also called as a digest algorithm, and can convert any data into a data string with a fixed length through a function, wherein the data string is generally represented by a 16-system character string, a one-to-one mapping relationship is formed between the function and the data string, and the hash algorithm has no requirement on the data for calculation, so that the hash calculation can be conveniently performed on the data. In addition, different blockchain networks have different requirements on the blockchain key, so that the generated blockchain key is different for different blockchain networks so as to be suitable for the corresponding blockchain networks.
Because the block chain key is generated by adopting at least one biological identification result as the key seed, when a user needs to use the block chain key, the user only needs to provide biological characteristics and/or behavior characteristics, and then the method provided by the invention can be used for conveniently generating the block chain key, so that the user does not need to specially memorize or keep the key seed or the block chain key, thereby effectively improving the safety and preventing the key seed and the block chain key from being stolen by other people.
According to the block chain key generation method based on the biometric identification result provided by the embodiment, the biometric characteristics and/or the behavior characteristics of the user are acquired, the acquired biometric characteristics and/or behavior characteristics are identified to obtain at least one biometric identification result, then the at least one biometric identification result is used as a key seed, the key seed is calculated by using a preset algorithm, and a block chain key is generated for use in transaction. By utilizing the technical scheme provided by the invention, at least one biological identification result can be conveniently adopted as the key seed to generate the block chain key, so that a user does not need to specially memorize or keep the key seed or the block chain key, the safety is effectively improved, the key seed and the block chain key are prevented from being stolen by other people, and the block chain key generation mode is optimized. When the digital assets are required to be operated, the user can quickly determine the own block chain key only by providing the inherent biological characteristics and/or behavior characteristics of the user, and the use of the user is greatly facilitated.
Fig. 2a is a flowchart illustrating a method for generating a blockchain key based on a biometric result according to another embodiment of the present invention, as shown in fig. 2a, the method includes the following steps:
step S200, acquiring the biological characteristics and/or behavior characteristics of the user.
Specifically, the feature acquisition device may be used to acquire a biometric feature and/or a behavior feature of the user, and the biometric feature and/or the behavior feature acquired by the feature acquisition device is acquired through a preset interface in step S200. Wherein the biometric characteristic may comprise one or more of the following characteristics: fingerprint features, hand features, face features, iris features, retinal features, genetic features, and pulse features; the behavioral characteristics may include: voice features and/or signature features, etc. The person skilled in the art may set the biological and/or behavioral characteristics according to actual needs, and is not limited herein.
Step S201, using a biometric device to identify the acquired biometric features and/or behavior features, and obtaining at least one biometric result.
After the biological characteristics and/or the behavior characteristics are acquired, the acquired biological characteristics and/or behavior characteristics are identified by using the existing biological identification equipment, so that at least one corresponding biological identification result is obtained. Wherein the at least one biometric identification result may include one or more of the following identification results: fingerprint recognition results, hand shape recognition results, face recognition results, voice print recognition results, iris recognition results, retina recognition results, gene recognition results, vein recognition results, and signature recognition results. Taking the acquired biological characteristics as fingerprint characteristics and face shape characteristics as an example, the fingerprint characteristics can be identified by using the existing fingerprint identification equipment to obtain a fingerprint identification result, and the face shape characteristics can be identified by using the existing face identification equipment to obtain a face identification result. In addition, the biometric device may also be a mobile phone, a computer, or the like having a biometric function, and is not limited specifically here. In a specific application, the obtained biometric result may be information composed of numbers or the like so as to be used for generating the blockchain key.
Step S202, at least one biological identification result is used as a key seed, and the key seed is calculated by using a preset algorithm to generate a block chain key.
When the number of the at least one biological identification result is one, the biological identification result can be directly used as a key seed; when the number of the at least one biometric result is multiple, the multiple biometric results may be combined according to a preset combination rule, and the combined biometric result is used as a key seed. The preset combination rule can be set by a person skilled in the art according to actual needs, and is not specifically limited herein. Taking the example that the biological recognition result comprises a voiceprint recognition result and an iris recognition result, and the voiceprint recognition result and the iris recognition result are respectively a group of information consisting of numbers, the voiceprint recognition result and the iris recognition result can be subjected to operation processing such as addition, and then the operation result is used as a key seed.
After the key seed is determined, the key seed can be calculated by using a preset algorithm such as a hash algorithm, and the block chain key is generated. Specifically, the key seeds may be calculated by using different preset algorithms, so as to generate different blockchain keys. In the present invention, the blockchain key is specifically a private key, and then after the blockchain key is generated, the corresponding public key can be generated by calculating the blockchain key using an asymmetric encryption algorithm.
Optionally, the generated blockchain key may further include: a blockchain root key and a blockchain subkey. Specifically, the key seed is calculated by using a first preset algorithm to generate a blockchain root key, then the blockchain root key is calculated by using a second preset algorithm to generate a blockchain subkey corresponding to the blockchain root key, and then the blockchain subkey corresponding to the blockchain root key is calculated by using a third preset algorithm to generate a blockchain subkey corresponding to the blockchain subkey. Similarly, the block chain subkey corresponding to the block chain subkey may also be calculated by using other preset algorithms, so as to generate more block chain subkeys. The number of the required block chain subkeys can be determined by those skilled in the art according to actual needs, and is not limited in detail here.
Fig. 2b shows a schematic diagram of a generation process of the blockchain key, and as shown in fig. 2b, the key seed is calculated by using a first preset algorithm to generate a blockchain root key, where the generated blockchain root key is the key a. And calculating the block chain root key by using a second preset algorithm, wherein the generated block chain sub-keys corresponding to the block chain root key comprise a key B, a key C, a key D and a key E, namely the key B, the key C, the key D and the key E are the block chain sub-keys corresponding to the key A. And respectively calculating a key B, a key C, a key D and a key E by using a third preset algorithm, wherein the generated corresponding block chain subkeys comprise a key F, a key G, a key H, a key I, a key J, a key K, a key L and a key M, the key F and the key G are block chain subkeys corresponding to the key B, the key H and the key I are block chain subkeys corresponding to the key C, the key J and the key K are block chain subkeys corresponding to the key D, and the key L and the key M are block chain subkeys corresponding to the key E. It can be seen that a plurality of different keys can be generated from the same key seed.
The first preset algorithm, the second preset algorithm, and the third preset algorithm may be the same algorithm or different algorithms, and are not specifically limited herein. Preferably, the first preset algorithm, the second preset algorithm and the third preset algorithm adopt a hash algorithm, the hash algorithm is a one-way algorithm, the data string can be conveniently calculated by using the data, but the data used is difficult to reversely deduce through the data string, so that even if a certain block chain sub-key is stolen by others, others are difficult to reversely deduce a block chain root key or a key seed through the block chain sub-key, thereby improving the security.
Step S203, generating a transaction address by using the blockchain key, and storing a preset algorithm for generating the blockchain key corresponding to the transaction address in the blockchain wallet, so as to generate a required blockchain key when performing a transaction.
The block chain key is calculated by using an encryption algorithm to generate a corresponding transaction address, the length of the transaction address is generally 34 bits, the transaction address can be public, and other people cannot reversely deduce the block chain key according to the transaction address. Control of all digital assets in a transaction address depends on ownership and control of the corresponding blockchain key. The same or different blockchain keys may be used for different transactions, and those skilled in the art may select the keys according to actual needs, which are not specifically limited herein.
It is common in the art to manage blockchain keys using blockchain wallets so that others can steal blockchain keys from blockchain wallets. In the invention, in order to avoid stealing the blockchain key from the blockchain wallet by others, the generated blockchain key is not stored in the blockchain wallet, but a preset algorithm for generating the blockchain key corresponding to the transaction address is stored, namely, the corresponding relation between the transaction address and the preset algorithm for generating the blockchain key is stored, so that the required blockchain key is generated by using the preset algorithm during transaction, thereby effectively improving the security and avoiding stealing the blockchain key by others. In addition, the blockchain wallet can also record transaction addresses in historical transactions of the user, such as recording transaction addresses where the user frequently transfers money and the like.
When a user needs to perform a transaction, only the biological characteristics and/or the behavior characteristics need to be provided, then the method provided by the invention can be used for conveniently generating the block chain key, specifically, the biological characteristics and/or the behavior characteristics of the user are obtained, then the obtained biological characteristics and/or the behavior characteristics are identified by using biological identification equipment such as a mobile phone, a computer and the like to obtain at least one biological identification result, then the at least one biological identification result is used as a key seed, the key seed is calculated by using a preset algorithm stored in the block chain wallet, and the block chain key is generated for use in the transaction. And when the plurality of transaction addresses correspond to different blockchain keys, correspondingly calculating the key seeds by using a preset algorithm which is stored in the blockchain wallet and corresponds to the transaction addresses and is used for generating the blockchain keys, and generating the corresponding blockchain keys.
According to the block chain key generation method based on the biological identification result provided by the embodiment, at least one biological identification result can be conveniently adopted as the key seed to generate the block chain key, different block chain keys can be generated according to the same key seed, and the generated block chain key is not stored in the block chain wallet, but a preset algorithm corresponding to the transaction address and used for generating the block chain key is stored, so that the block chain key required by the transaction is generated by using the preset algorithm, the safety is further improved, the block chain key is effectively prevented from being stolen by other people, and the block chain key is conveniently generated by a user. When the digital assets are required to be operated, the user can quickly determine the own block chain key only by providing the inherent biological characteristics and/or behavior characteristics of the user, and the use of the user is greatly facilitated.
