Fig. 1 illustrates a flow chart of some embodiments of an authentication method of the present disclosure.
As shown in fig. 1, the method includes: step 130, providing a plurality of sub-pictures for a user; step 140, transmitting the verification code; and step 150, authenticating the user.
In step 130, a plurality of sub-pictures obtained from the blockchain are provided to the user, and the plurality of sub-pictures can be spliced into one authentication picture. For example, a plurality of sub-images in a disordered order may be displayed on a user's registration or login interface for the user to splice. In some embodiments, the plurality of sub-images may be encrypted and provided to the user to further improve the reliability of user authentication.
In step 140, in case the user is able to splice the plurality of sub-pictures into an authentication picture, a verification code generated from the plurality of sub-pictures is transmitted to the user. For example, after the user completes the splice, the user may click on the obtain verification code button, and the system displays the processed verification code on the interface; and the verification code can also be sent to the user terminal in response to the user completing the splicing correctly.
In step 150, the user is authenticated in the event that the user returns the correct verification code. For example, the user may enter the retrieved verification code in the interface. Thus, the user identity is subjected to double authentication through the graph splicing and the verification code, and the reliability of user authentication is improved.
In some embodiments, the technical solutions of the present disclosure may be implemented by the embodiment in fig. 2.
Fig. 2 shows a flow chart of further embodiments of the authentication method of the present disclosure.
As shown in fig. 2, the method includes: step 110, obtaining a plurality of sub-pictures; step 120, generating a verification code; step 130, providing a plurality of sub-pictures for a user; step 140, transmitting the verification code; and step 150, authenticating the user.
In step 110, a plurality of sub-pictures are obtained from the blockchain, and the plurality of sub-pictures can be spliced into one authentication picture. For example, multiple sub-pictures may be pre-stored in the blockchain for retrieval when authenticating a user.
In step 120, a verification code is generated from the plurality of sub-pictures. For example, the verification code may be generated from hash values of a plurality of sub-pictures.
In step 130, a plurality of sub-pictures are provided to the user.
In step 140, in case the user is able to splice the plurality of sub-pictures into an authentication picture, a verification code is sent to the user.
In step 150, the user is authenticated in the event that the user returns the correct verification code.
In some embodiments, multiple sub-pictures may be stored in the blockchain by the steps in fig. 3 prior to step 110.
Fig. 3 illustrates a flow chart of some embodiments of sub-picture storage.
As shown in fig. 3, the process includes: step 101, dividing the sub-picture; and step 102, agglomerating to store the sub-pictures.
In step 101, the authentication picture is divided into a plurality of sub-pictures. For example, the sequence of the pictures in the gallery may be disordered, one picture may be randomly extracted as an authentication picture, and the authentication picture may be cut into multiple sub-pictures according to a certain proportion.
In step 102, each sub-picture is stored in the blockchain after being agglomerated, and the corresponding block of each sub-picture contains the pre-hash value. For example, each sub-graph is stored as a block, and the blocks are concatenated into a blockchain in the order of storage.
In some embodiments, step 102 may be implemented by the steps in fig. 4.
Fig. 4 shows a flow chart of some embodiments of step 102 in fig. 3.
As shown in fig. 4, step 102 includes: step 1021, storing the sub-picture; step 1022, storing the hash value; step 1023, calculating a front hash value; and step 1024, storing the pre-hash value.
In step 1021, the sub-picture is stored in the block body of the block.
In step 1022, the hash value of the sub-picture is stored in the block header of the block. For example, the SHA256 method may be used to calculate the hash value of the sub-picture.
In step 1023, the hash value of the block header of the previous block of the block is calculated as the pre-hash value. The block heights of the blocks in the block chain are different according to the agglomeration sequence, namely, the block height of the blocks agglomerated earlier is lower than the block height of the blocks agglomerated later. A block preceding a block may be understood as a block having a block height that is higher than the block of the first level of the current block.
In step 1024, the pre-hash value is stored in the block header of the block.
Steps 1021-1024 can be better understood by the schematic diagram in fig. 5.
Fig. 5 illustrates a block diagram of some embodiments of a block structure.
As shown in FIG. 5, the blockchain has agglomerated to form a plurality of blocks, such as block 51, block 52, and the like. Block 52 blocks earlier than block 51, i.e., block 52 is the previous block to block 51. Sub-picture a is stored in block bank 512 of block 51 and sub-picture b is stored in block bank 522 of block 52.
The block header 511 of the block 51 includes the hash value of the sub-picture a and the pre-hash value of the block 51. The pre-hash value of block 51 is the hash value of block header 521 of block 52.
For example, the hash value of the sub-picture b in the block header 521 is a string of 256-bit numbers, the front hash value of the block 52 is also a string of 256-bit numbers, the hash value of the sub-picture b and the front hash value of the block 52 may be combined into a string of 512-bit numbers, and then the hash value of the string of 512-bit numbers is calculated and stored in the block header 511 as the front hash value of the block header 511. The pre-hash value of block 52 may also be obtained as described above.
By the above-described embodiment, the hash value (including information of the current stored content) and the pre-hash value (including information of all the stored contents before) of the current block are included in the block header of each block in the blockchain. That is, the hash value of the block header of each block includes the content information stored in all the blocks in the blockchain.
Based on such a structure, any one of the stored contents in the blockchain is tampered with, which results in a change in the hash value of the blockhead of the current block. If one tampers with one of the blocks, the hash of the block header of that block becomes that block will not be able to be attached to the blockchain. Therefore, the content stored in the blockchain can be ensured not to be tampered randomly, and the reliability can be improved by taking the content as the basis of user authentication.
In the embodiment, the user is subjected to double authentication by the jigsaw and the input of the verification code, and the reliability of the sub-picture for verification and the corresponding verification code thereof is ensured by utilizing the block chain technology, so that the reliability of the user authentication is improved.
Fig. 6 illustrates a block diagram of some embodiments of an authentication device of the present disclosure.
As shown in fig. 6, the authentication apparatus 6 includes a transmitter 61 and a processor 62.
The transmitter 61 is configured to provide the plurality of sub-pictures to the user, the plurality of sub-pictures being capable of being spliced into one authentication picture, and to transmit the authentication code to the user in case the user is capable of splicing the plurality of sub-pictures into the authentication picture. For example, the processor 62 encrypts the plurality of sub-images, and the transmitter 61 provides the encrypted plurality of sub-images to the user
The processor 62 is arranged to generate a verification code from the plurality of sub-pictures and to pass the authentication of the user in case the user returns the correct verification code. For example, the processor 62 randomly extracts a picture as an authentication picture by scrambling the order of pictures in the gallery. The processor 62 divides the authentication picture into a plurality of sub-pictures, and each sub-picture is stored in the blockchain after being subjected to the agglomeration processing. The corresponding block of each sub-picture contains the pre-hash value.
In some embodiments, processor 62 stores the sub-picture in a block body of the block, the hash value of the sub-picture in a block header of the block, and the pre-hash value in the block header of the block. The pre-hash value is the hash value of the block header of the block preceding the block.
In some embodiments, the user is doubly authenticated by the jigsaw and the input verification code, and the reliability of the sub-picture for verification and the corresponding verification code thereof is ensured by using the blockchain technology, so that the reliability of the user authentication is improved.
