The illustrative embodiments of the present application and their descriptions are used to explain the present application and do not constitute an improper limitation of the present application. In the drawings:

[0040] Figure 2 is a schematic structural diagram of a fingerprint entry device based on blockchain provided by an embodiment of this specification. Detailed Description of the Embodiments

[0041] To make the objectives, technical solutions, and advantages of this specification clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with the specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0042] The following will describe in detail the technical solutions provided by each embodiment of the present application in conjunction with the drawings.

[0043] Figure 1 is a flowchart of a fingerprint entry method based on blockchain provided by an embodiment of this specification. As Figure 1 shown, a fingerprint entry method based on blockchain provided by an embodiment of this specification specifically includes the following steps:

[0044] S101, when performing a fingerprint entry operation, receive the first fingerprint information from the user terminal.

[0045] In some embodiments of the present application, the first fingerprint information may be image information. Of course, the first fingerprint information may also be other types of information.

[0046] When performing a fingerprint entry operation, step S101 may be executed after receiving the fingerprint entry request message from the user terminal.

[0047] S102, in the case where the first fingerprint information is not the first entry, determine the entry serial number of the first fingerprint information.

[0048] Before step S102, it is necessary to determine whether the first fingerprint information is the first entry. Here, the first entry means that the device for entering fingerprints has not entered fingerprints before.

[0049] In the case where the first fingerprint information is not the first entry, the entry serial number of the first fingerprint information can be determined. For example, the first fingerprint information is the third fingerprint information entered by the device for entering fingerprints.

[0050] In some embodiments of the present application, in the case where the first fingerprint information is the first entry, before entering the first fingerprint information, an entry request is received from the user terminal, and the entry request includes an entry password.

[0051] In the case where the entry password is consistent with the preset password, the first fingerprint information is written into the fingerprint template set and the blockchain respectively.

[0052] Through the above solution, the security of the first fingerprint entry can be guaranteed.

[0053] It should be noted that, in order to further ensure the security of the first fingerprint entry, the entry password can be encrypted to obtain the encrypted entry fingerprint and then sent.

[0054] S103. According to the entry serial number of the first fingerprint information, it is determined whether other fingerprint information with an entry serial number before the entry serial number of the first fingerprint information is received before receiving the first fingerprint information from the user terminal.

[0055] Among them, the other fingerprint information is the fingerprint information that has been written into the fingerprint template set before the first fingerprint information.

[0056] In some embodiments of the present application, according to the entry serial number of the first fingerprint information, it is determined whether other fingerprint information with an entry serial number before the entry serial number of the first fingerprint information is received before receiving the first fingerprint information from the user terminal, which is implemented based on the corresponding smart contract deployed in the blockchain.

[0057] S104. Before receiving the first fingerprint information from the user terminal, if other fingerprint information with an entry serial number before the entry serial number of the first fingerprint information is received, the first fingerprint information is written into the fingerprint template set and stored in the blockchain.

[0058] In order to further ensure the security of fingerprint entry, in some embodiments of the present application, before entering the first fingerprint information into the fingerprint template set, the following steps may be included:

[0059] It is determined whether the time interval between the received first fingerprint information and the received other fingerprint information is less than the corresponding preset threshold.

[0060] Through the above solution, in the case where the time interval between the first fingerprint information and the other fingerprint information is less than the corresponding preset threshold, S104 is executed.

[0061] It should be noted that the time interval between the first fingerprint information and other fingerprint information can be the time interval between the first fingerprint information and the first received other fingerprint information among other fingerprint information.

[0062] In some embodiments of the present application, after other fingerprint information is written into the fingerprint template set, it is written into the blockchain respectively, which can ensure that the fingerprint information is not easily tampered with and improve the security of fingerprint entry.

[0063] In some embodiments of the present application, before the first fingerprint information is entered into the fingerprint template set, the method further includes:

[0064] Determine that the received other fingerprint information matches the other fingerprint information in the blockchain.

[0065] Before the first fingerprint information is entered into the fingerprint template set, it is necessary to confirm the received other fingerprint information to determine whether the received other fingerprint information matches the other fingerprint information in the blockchain. Only when they match can the first fingerprint information be entered into the fingerprint template set.

[0066] In some embodiments of the present application, the entry sequence number of the first fingerprint information is written into the blockchain for storage.

[0067] For example, if the first fingerprint information is the third fingerprint entered by the device for entering fingerprints, then before the first fingerprint is entered, the first fingerprint and the second fingerprint entered by the device need to be entered first before the first fingerprint information can be written into the fingerprint template set, that is, it represents a successful entry.

[0068] Based on the above technical solution, when receiving the entered fingerprint, it is possible to determine the entry sequence number of the entered fingerprint. According to the entry sequence number, it is confirmed whether the fingerprint information before the entry sequence number of the entered fingerprint has been entered. Only when there is an entry can the entered fingerprint be written into the fingerprint template set, improving the security of fingerprint entry, effectively avoiding losses caused by security problems in fingerprint entry, and improving the user experience. Moreover, writing the entered fingerprint into the blockchain for storage can prevent the fingerprint information from being tampered with and reduce security.

[0069] Based on the same idea, some embodiments of the present application also provide the device and the non-volatile computer storage medium corresponding to the above method.

[0071] At least one processor; and,

[0072] A memory communicatively connected to the at least one processor; wherein,

[0073] The memory stores instructions executable by the at least one processor, and when the instructions are executed by the at least one processor, the at least one processor is enabled to:

[0074] Receive first fingerprint information from a user terminal during a fingerprint entry operation;

[0075] When the first fingerprint information is not the first entry, determine the entry sequence number of the first fingerprint information;

[0076] According to the entry sequence number of the first fingerprint information, determine whether other fingerprint information with an entry sequence number before that of the first fingerprint information was received before receiving the first fingerprint information from the user terminal;

[0077] Wherein the other fingerprint information is fingerprint information that has been written into the fingerprint template set before the first fingerprint information;
