fig. 3 is a schematic diagram of a user identity authentication system for a blockchain wallet provided in the present invention.
Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will be made with reference to the accompanying drawings. It is obvious that the drawings in the following description are only some examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.
The invention provides a user identity authentication method for a block chain wallet, which can authenticate the uniqueness of the user identity when one user creates different wallets through different mobile phone numbers or adopts different equipment to log in the wallets.
The flow chart of the user identity authentication method for the blockchain wallet provided by the invention is shown in fig. 1, and specifically includes the following steps.
S100: the method comprises the steps of acquiring a device ID for creating or importing the wallet, a wallet ID list generated by creating or importing the wallet, allocating user IDs for identifying the device ID and the wallet ID list, and establishing a first mapping relation among the wallet IDs, the device ID and the user ID in the wallet ID list.
For example, when the user a creates or imports a wallet by using the device a, the wallet APP binds a wallet ID list generated by creating or importing the wallet with the device ID of the device a and sends the binding to the cloud server, the cloud server assigns a user ID to the binding, and establishes a first mapping relationship among each wallet ID in the wallet ID list, the device ID of the device a and the user ID.
For another example, when the user B creates or imports a wallet using the device B, the wallet APP binds a wallet ID list generated by creating or importing the wallet with the device ID of the device B and sends the binding to the cloud server, the cloud server assigns a user ID to the binding, and establishes a first mapping relationship among each wallet ID in the wallet ID list, the device ID of the device B, and the user ID.
By analogy, the cloud server establishes a first mapping relation between the device ID of the wallet created or imported by the user, each wallet ID in the wallet ID list generated by the wallet created or imported and the corresponding user ID.
Through the first mapping relationship, it can be known that a plurality of different wallet IDs in the wallet ID list correspond to the same user ID, and therefore, a plurality of different wallet IDs corresponding to the same user ID are created by the same user.
S200: acquiring the equipment ID of the login wallet, the wallet ID list of the login wallet and the mobile phone number of the login wallet, and establishing a second mapping relation between each wallet ID, the equipment ID of the login wallet, the mobile phone number of the login wallet in the wallet ID list of the login wallet and the corresponding user ID.
For example, the user a may log in a wallet on the device a, or may log in a wallet on the device B, how to authenticate the user identities of different wallets logged in different login devices, and in this step, a second mapping relationship is established between each wallet ID in the wallet ID list of the login wallet, the device ID of the login wallet, the mobile phone number of the login wallet, and the corresponding user ID.
Specifically, the user A creates a wallet through the device A, when the user A logs in the wallet through the device B, the wallet APP sends the device ID of the device B, a wallet ID list of the login wallet and the mobile phone number of the login wallet to the cloud server, and the cloud server establishes a second mapping relation between each wallet ID in the wallet ID list of the login wallet, the device ID of the device B, the mobile phone number of the login wallet and the corresponding user ID.
S300: and authenticating the uniqueness of the user identities of the plurality of different wallet IDs through the cross matching of the first mapping relation and the second mapping relation.
Specifically, traversing each wallet ID in a wallet ID list of the currently logged-in wallet;
inquiring the corresponding user ID of each traversed wallet ID according to the first mapping relation and the second mapping relation in a cross matching manner;
and authenticating a plurality of different user IDs corresponding to a plurality of different wallet IDs existing in a wallet ID list of the currently logged-in wallet as the same user.
For example, user a created wallet a on device a, included wallet ID1 and wallet ID2 in the list of wallets in wallet a, and user a created wallet B on device B, also included wallet ID3 and wallet ID4 in the list of wallets in wallet B.
According to the first mapping relationship, the cloud server allocates a user IDA to the device a, the wallet ID1 and the wallet ID2, and stores the device IDA of the device a, the wallet ID1, the wallet ID2 and the user IDA in a mapping relationship list, for example, by using the user IDA as a key.
Similarly, the cloud server assigns a user IDB to device B, wallet ID3, wallet ID4, and stores the device IDB, wallet ID3, wallet ID4, and user IDB of device B in a mapping list, for example, using the user IDB as a key.
When the user a logs in the wallet a on the device B, and at the same time, the device B still has the logged-in wallet B, the wallet APP running in the device B sends all wallet lists (including the wallet list of wallet a and the wallet list of wallet B) currently logged in the wallet in the device B, the device IDB of device B, and the phone number of the logged-in wallet to the cloud server, after the cloud server obtains the wallet ID1, the wallet ID2, the wallet ID3, and the wallet ID4, the cloud server determines that the wallet IDs 1, the wallet ID2, the wallet ID3, and the wallet ID4 all exist by traversing the stored wallet ID lists, queries the corresponding user IDA and user IDB, and according to the second mapping relationship, the cloud server maps the device ID of device B, the wallet ID1, the wallet ID2, the phone number of the logged-in wallet, and the user IDA, and performing association mapping on the device IDB, the wallet ID3, the wallet ID4, the mobile phone number of the login wallet and the user IDB of the device B, and storing the association mapping into a mapping relation list.
According to the first mapping relationship and the second mapping relationship, the device IDB is associated with the mapped wallet ID1, the wallet ID2, the wallet ID3 and the wallet ID4, the wallet ID1 and the wallet ID2 are associated with the mapped user IDA, and the wallet ID3 and the wallet ID4 are associated with the mapped user IDB, so that the cloud server can authenticate the user IDA and the user IDB corresponding to the wallet ID1, the wallet ID2, the wallet ID3 and the wallet ID4 stored in the device IDB as the same user, that is, the same user creates the wallet ID1, the wallet ID2, the wallet ID3 and the wallet ID4 by using different user IDs.
Accordingly, it can be further determined that the user has logged in to the same wallet using different devices according to the mapping relationship between the device ID and the user ID and the wallet ID, for example, the mapping relationship between the device IDA and the wallet ID1 and between the device IDA and the wallet ID1 and between the device IDB and the user IDA, and it can be known that the user has logged in to the wallet ID1 through the device IDA and the device IDB, respectively.
It should be noted that the above-mentioned user identity uniqueness authentication for different wallet IDs is based on the principle that the private assets of the blockchain wallet are not shareable, i.e. one wallet ID can only belong to one user.
Further, after the plurality of different user IDs corresponding to the plurality of different wallet IDs are authenticated as the same user through the cross matching of the first mapping relationship and the second mapping relationship, the method further includes merging and mapping the wallet ID, the device ID, and the mobile phone number, which are respectively associated and mapped with the plurality of different user IDs authenticated as the same user, with one of the plurality of different user IDs.
For example, wallet ID1 corresponds to association mapping user ID1, wallet ID2 corresponds to association mapping user ID2, and wallet ID3 corresponds to association mapping user ID3, and wallet ID1, wallet ID2, user ID1, user ID2, and user ID3 corresponding to wallet ID3 are obtained by many-to-many association mapping cross matching, so that wallet ID1, wallet ID2, wallet ID3, corresponding device ID, and mobile phone number respectively associated with user ID1, user ID2, and user ID3 can be merged and mapped with user ID1, that is, data respectively associated and mapped with user ID1, user ID2, and user ID3 are merged and mapped into a data group using user ID1 as a key.
It should be further noted that the device ID refers to an identifier capable of uniquely identifying a device, for example, a smart phone, each smart phone has a unique serial number, the serial number is the device ID, the user ID is generated by matching the wallet ID with the cloud server, and is unique, for example, when the cloud server obtains the wallet ID, it is determined whether the wallet ID exists in the stored wallet ID list, if so, the allocated user ID is associated and mapped with the wallet ID, and if not, the wallet ID is a new user, and then an unique user ID is allocated to the wallet ID.
The wallet ID in the invention is generated based on mnemonic words through a certain rule, so that even if the wallet ID is leaked, the security of the private property of the user wallet can be ensured. The wallet ID generation process of the present invention includes the following steps.
Restoring the mnemonic words into seeds according to a predetermined bitcoin improvement protocol;
generating a master private key according to the seed;
generating a master public key according to the master private key;
the wallet ID is generated from the master public key.
First, it should be noted that the process of generating the mnemonic word is as follows: a random seed is generated by a cryptographically secure pseudo-random number generator, and a mnemonic is generated from the seed.
Here, the predetermined Bitcoin Improvement Protocol (BIP) includes, but is not limited to, BIP32, BIP39, BIP44, etc., and hereinafter, taking the example of restoring the mnemonic word into the seed according to the BIP39 rule, a specific generation process of a wallet ID is as shown in fig. 2, specifically, 1) restoring the mnemonic word into the seed according to the BIP39 rule, and then obtaining a main private key and a main chain code from the restored seed according to HMAC-SHA512 algorithm (one-way hash operation); 2) the main private key generates a main public key through an elliptic curve (the elliptic curves of different main chains are inconsistent), wherein the main public key can be deduced, and the main private key cannot be deduced; 3) and (4) carrying out SHA256 operation twice on the master public key to obtain the wallet ID.
The invention provides a user identity authentication method for a blockchain wallet, which is based on the principle that private properties of the blockchain wallet can not be shared, and is characterized in that a wallet ID and an equipment ID which are created or led in by a user are subjected to first association mapping with an allocated user ID, when the user logs in the wallet, the equipment ID of the login equipment, all wallet IDs of the login wallet, a mobile phone number and the corresponding user ID are subjected to second association mapping, the identities of different user IDs corresponding to a plurality of different wallet IDs are authenticated through cross matching of a plurality of association mapping relations, when one user uses a plurality of mobile phone numbers to create different wallets on different equipment, the identity of the user can be uniquely determined, and further, the user identity of the blockchain can be effectively managed.
Based on the above method for authenticating the user identity of the blockchain wallet, the invention further provides a system for authenticating the user identity of the blockchain wallet, the schematic diagram of which is shown in fig. 3 and comprises a first mapping relation establishing module 1, a second mapping relation establishing module 2 and a user identity authenticating module 3.
The first mapping relation establishing module 1 is configured to obtain a device ID for creating or importing a wallet, a wallet ID list generated by creating or importing a wallet, allocate a user ID for identifying the device ID and the wallet ID list, and establish a first mapping relation among wallet IDs, the device ID, and the user ID in the wallet ID list; the second mapping relation establishing module 2 is used for acquiring the equipment ID of the login wallet, the wallet ID list in the login wallet and the mobile phone number of the login wallet, and establishing a second mapping relation between each wallet ID in the wallet ID list of the login wallet, the equipment ID of the login wallet, the mobile phone number of the login wallet and the corresponding user ID; the user identity authentication module 3 is configured to authenticate uniqueness of user identities of a plurality of different wallet IDs through cross matching of the first mapping relationship and the second mapping relationship.
The step S100 is referred to for the first mapping relationship establishing module 1 according to a specific process of establishing or importing a wallet to establish a first mapping relationship, and the step S200 is referred to for the second mapping relationship establishing module 2 according to a specific process of establishing a second mapping relationship for a login wallet, which is not described herein again.

the query module 32 is configured to query the corresponding user ID of each wallet ID traversed by the first mapping relationship and the second mapping relationship cross-matching pair;
the authentication module 33 is configured to authenticate a plurality of different user IDs corresponding to a plurality of different wallet IDs existing in the wallet ID list of the currently logged-in wallet as the same user.
For example, user a created wallet a on device a, included wallet ID1 and wallet ID2 in the list of wallets in wallet a, and user a created wallet B on device B, also included wallet ID3 and wallet ID4 in the list of wallets in wallet B.
The first mapping relationship establishing module 1 allocates a user IDA to the device a, the wallet ID1 and the wallet ID2 according to the first mapping relationship, and stores the device IDA, the wallet ID1, the wallet ID2 and the user IDA of the device a in a mapping relationship list, for example, by using the user IDA as a keyword.
Similarly, the first mapping relationship establishing module 1 allocates a user IDB to the device B, the wallet ID3 and the wallet ID4, and stores the device IDB, the wallet ID3, the wallet ID4 and the user IDB of the device B in a mapping relationship list, for example, by using the user IDB as a key word.
When the user a logs in the wallet a on the device B, and at this time, the device B also has a registered wallet B, the wallet APP running in the device B sends all wallet lists (including the wallet list of wallet a and the wallet list of wallet B) currently logged in the wallet in the device B, the device IDB of the device B, and the phone number of the registered wallet to the second mapping relation establishing module 2, after the second mapping relation establishing module 2 obtains the wallet ID1, the wallet ID2, the wallet ID3, and the wallet ID4, the second mapping relation establishing module 2 determines that the wallet ID1, the wallet ID2, the wallet ID3, and the wallet ID4 all exist by traversing the stored wallet ID lists, queries the corresponding user IDA and user IDB by the second mapping relation establishing module 2, and according to the second mapping relation, the second mapping relation establishing module 2 determines the device IDB of the device B, the wallet ID B, and the wallet ID4 to be in the second mapping relation, And performing association mapping on the wallet ID1, the wallet ID2, the mobile phone number of the login wallet and the user IDA, performing association mapping on the device IDB, the wallet ID3 and the wallet ID4 of the device B, the mobile phone number of the login wallet and the user IDB, and storing the association mapping into a mapping relation list.
The traversal module 31 traverses each wallet ID in the wallet ID list of the currently logged-in wallet to obtain a wallet ID1, a wallet ID2, a wallet ID3 and a wallet ID4, the query module 32 cross-matches the first mapping relationship and the second mapping relationship, the query device IDB corresponds to the association mapping wallet ID1, a wallet ID2, a wallet ID3 and a wallet ID4, the query device IDB corresponds to the association mapping user IDA and the query device ID1 and the wallet ID2 correspond to the association mapping user IDA, and the query device ID3 and the wallet ID4 correspond to the association mapping user IDB, so that the authentication module 33 authenticates the user IDA and the user IDB corresponding to the wallet ID1, the wallet ID2, the wallet ID3 and the wallet ID4 stored in the device IDB as the same user, that is, the same user creates a wallet ID1, a wallet ID2, a wallet ID3 and a wallet ID4 by using different user IDs.
Accordingly, it can be further determined that the user has logged in to the same wallet using different devices according to the mapping relationship between the device ID and the user ID and the wallet ID, for example, the mapping relationship between the device IDA and the wallet ID1 and between the device IDA and the wallet ID1 and between the device IDB and the user IDA, and it can be known that the user has logged in to the wallet ID1 through the device IDA and the device IDB, respectively.
It should be noted that the above-mentioned user identity uniqueness authentication for different wallet IDs is based on the principle that the private assets of the blockchain wallet are not shareable, i.e. one wallet ID can only belong to one user.
Further, the system for authenticating the user identity of the blockchain wallet further comprises a merging and mapping module 4, wherein after the multiple different user IDs corresponding to the multiple different wallet IDs are authenticated as the same user through the cross matching of the first mapping relation and the second mapping relation, the merging and mapping module 4 is used for merging and mapping the wallet ID, the device ID and the mobile phone number which are respectively associated and mapped with the multiple different user IDs authenticated as the same user with one of the multiple different user IDs.
For example, wallet ID1 corresponds to association mapping user ID1, wallet ID2 corresponds to association mapping user ID2, wallet ID3 corresponds to association mapping user ID3, and wallet ID1, wallet ID2, user ID1, user ID2, and user ID3 corresponding to wallet ID3 are obtained by cross-matching many-to-many association mappings, and then the merge mapping module 4 merges and maps wallet ID1, wallet ID2, wallet ID3, corresponding device ID, and mobile phone number, which are respectively associated with user ID1, user ID2, and user ID3, with user ID1, that is, the merge mapping module 4 merges and maps data respectively associated and mapped with user ID1, user ID2, and user ID3 into a data set with user ID1 as a key.
It should be further noted that the device ID refers to an identifier capable of uniquely identifying a device, for example, a smart phone is taken as an example, each smart phone has a unique serial number, the serial number is the device ID, and the user ID is generated by matching a wallet ID and is unique, for example, when the first mapping relationship establishing module 1 and the second mapping relationship establishing module 2 establish a mapping relationship, it is first determined whether the acquired wallet ID exists in a stored wallet ID list, if so, the allocated user ID is associated with the wallet ID for mapping, and if not, the wallet ID is a new user, and then an unique user ID is allocated to the wallet ID.
