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.

Referring to fig. 1, fig. 1 is a flowchart of an implementation of an information processing method according to an embodiment of the present application, which may include:

step S11: the method comprises the steps that a control medium receives a first fingerprint feature file sent by first terminal equipment; the first fingerprint feature file at least comprises fingerprint feature information of a user.

The first terminal device sends a first fingerprint characteristic file to the control medium, wherein the first fingerprint characteristic file at least comprises fingerprint characteristic information of a user.

The first terminal device can actively upload the fingerprint characteristic information to the control medium after actively collecting the fingerprint of the user and generating the fingerprint characteristic information according to the collected fingerprint. I.e. the first fingerprint profile does not include the identification of the user. Or,

the first terminal device can actively upload the fingerprint feature file containing the fingerprint feature information and the user identification mark to the control medium after actively collecting the fingerprint of the user and generating the fingerprint feature information according to the collected fingerprint. That is, the first fingerprint feature file includes both fingerprint feature information and the identification of the user. Or,

the first terminal device can collect the user fingerprint in response to the fingerprint input instruction after receiving the fingerprint input instruction sent by the control medium, generate fingerprint characteristic information according to the collected fingerprint, and upload the fingerprint characteristic information to the control medium. I.e. the first fingerprint feature information does not include the identification of the user. Or,

the first terminal device can collect the user fingerprint in response to the fingerprint input instruction after receiving the fingerprint input instruction sent by the control medium, generate fingerprint characteristic information according to the collected fingerprint, and upload the fingerprint characteristic file containing the fingerprint characteristic information and the user identification mark to the control medium. That is, the first fingerprint feature file includes both fingerprint feature information and the identification of the user.

The first terminal device can transmit the first fingerprint feature file to the control medium and can store the fingerprint feature information locally, so that the first terminal device can authenticate the identity of the user by using the locally stored fingerprint feature information.

In this embodiment of the application, the first terminal device may only upload the fingerprint feature information to the control medium, and may also upload both the fingerprint feature information and the user identification identifier to the control medium. For example, if the first terminal device cannot acquire the user identification, the first terminal device may only upload the fingerprint feature information to the control medium; if the first terminal equipment can acquire the user identification mark, the first terminal equipment can upload the fingerprint characteristic information and the user identification mark to the control medium together; or, even if the first terminal device can obtain the user identification, the first terminal device may only upload the fingerprint feature information to the control medium.

The control medium refers to software or equipment capable of communicating with the first terminal device, and for example, the control medium may be equipment such as an upper computer, a mobile phone, a gateway, and the like. Alternatively, the control medium may be application software installed in the electronic device. The first terminal device can be an electronic device such as a mobile phone, a door lock, a fingerprint reader or an entrance guard.

The control medium and the first terminal device may perform data transmission through a channel with a lower data transmission rate, such as bluetooth or zigbee, or perform data transmission through a channel with a higher data transmission rate, such as WIFI.

If the control medium and the first terminal device communicate with each other through a channel with a low data transmission rate, the first terminal device may split the first fingerprint feature file uploaded to the control medium into a plurality of data packets with fixed lengths, and upload the plurality of data packets to the control medium one by one.

Step S12: and the control medium sends a second fingerprint feature file to the cloud server, wherein the second fingerprint feature file comprises the identification of the user and the fingerprint feature information of the user, so that the cloud server stores the second fingerprint feature file.

In a case that the first terminal device does not upload the user identifier to the control medium, the user identifier may be obtained by the control medium, for example, the control medium may receive the user identifier input by the user, or the control medium collects the identifier information of the user through the collecting device (for example, reads the id card information, or collects the user image, etc.).

The control medium can automatically send the second fingerprint feature file to the cloud server after receiving the first fingerprint feature file sent by the first terminal device, and can also send the second fingerprint feature file to the cloud server after receiving a sending instruction triggered by a user.

If the first fingerprint feature file comprises the fingerprint feature information and the identification mark of the user, the control medium can directly forward the first fingerprint feature file to the cloud server after receiving the first fingerprint feature file sent by the first terminal device. Or, after receiving the first fingerprint feature file sent by the first terminal device, the control medium performs simple verification on the first fingerprint feature file, for example, determines whether the total data length of the first fingerprint feature file is the same as the total data length reported by the first terminal device, if so, the verification is passed, otherwise, the verification is not passed. And only when the verification is passed, the control medium forwards the first fingerprint feature file to the cloud server, otherwise, the control medium forbids to forward the first fingerprint feature file to the cloud server. That is to say, when the first fingerprint feature file includes both the fingerprint feature information and the identification of the user, the second fingerprint feature file is the first fingerprint feature file.

If the first fingerprint feature file does not contain the identification mark of the user, the control medium can directly send a second fingerprint feature file containing the first fingerprint feature file and the locally obtained identification mark of the user to the cloud server after receiving the first fingerprint feature file sent by the first terminal device. Or, after receiving the first fingerprint feature file sent by the first terminal device, the control medium performs simple verification on the first fingerprint feature file, for example, determines whether the total data length of the first fingerprint feature file is the same as the total data length reported by the first terminal device, if so, the verification is passed, otherwise, the verification is not passed. And only when the verification is passed, the control medium sends the second fingerprint feature file to the cloud server, otherwise, the control medium prohibits sending the second fingerprint feature file to the cloud server.

After receiving the second fingerprint feature file, the cloud server may store the second fingerprint feature file in a plaintext form, or may store the second fingerprint feature file in a ciphertext form.

Step S13: and the control medium sends a fingerprint characteristic information downloading request to the cloud server, wherein the fingerprint characteristic information downloading request carries the identification mark of the user.

The request for downloading the fingerprint feature information sent by the control medium to the cloud server may be generated by triggering the control medium by a user operating the control medium. Or,

the request sent by the control medium to the cloud server to download the fingerprint feature information may be triggered and generated and sent to the control medium by the user operating the first terminal device, or triggered and generated and sent to the control medium by the user operating the second terminal device. That is, the control intermediary forwards the request for downloading the fingerprint feature information sent by the first terminal device or the second terminal device to the cloud server.

Step S14: and the control medium receives the fingerprint characteristic information sent by the cloud server.

And the cloud server responds to the fingerprint characteristic information downloading request and sends the fingerprint characteristic information corresponding to the identification mark of the user to the control medium.

The fingerprint feature information corresponding to the identification mark of the user is the fingerprint feature information contained in the second fingerprint feature file containing the identification mark of the user.

In an optional embodiment, in a case that the fingerprint feature information download request is generated and sent by the control medium, after receiving the fingerprint feature information download request, the cloud server may first determine whether the control medium has an authority to download the fingerprint feature information before issuing the fingerprint feature information to the control medium, and if the control medium has the authority to download the fingerprint feature information, the cloud server issues the fingerprint feature information to the control medium, otherwise, the cloud server prohibits issuing the fingerprint feature information to the control medium.

Furthermore, in addition to determining whether the control medium has the right to download the fingerprint feature information, it may also determine whether the terminal device (i.e., the terminal device corresponding to the identification identifier of the terminal device carried in the request for downloading the fingerprint feature information) has the right to download the fingerprint feature information. The cloud server issues the fingerprint feature information to the control medium only under the condition that the terminal equipment and the control medium both have the authority of downloading the fingerprint feature information, otherwise, the cloud server prohibits issuing the fingerprint feature information to the control medium.

One implementation manner of determining whether the control medium has the right to download the fingerprint feature information may be:

and judging whether the identification mark of the control medium carried in the request for downloading the fingerprint characteristic information is a preset first identification mark or not.

If the judgment result is yes, determining that the control medium has the authority for downloading the fingerprint characteristic information, otherwise, determining that the control medium does not have the authority for downloading the fingerprint characteristic information.

One implementation manner of determining whether the terminal device has the right to download the fingerprint feature information may be:

and judging whether the identification mark of the terminal equipment carried in the request for downloading the fingerprint characteristic information is a preset second identification mark.

If the judgment result is yes, the terminal equipment is determined to have the authority for downloading the fingerprint characteristic information, otherwise, the terminal equipment is determined not to have the authority for downloading the fingerprint characteristic information.

In an optional embodiment, in a case that the fingerprint feature information download request is generated and sent by the terminal device, after receiving the fingerprint feature information download request, the cloud server may first determine whether the terminal device has an authority to download the fingerprint feature information before issuing the fingerprint feature information to the control medium, and if the terminal device has the authority to download the fingerprint feature information, the cloud server issues the fingerprint feature information to the control medium, otherwise, the cloud server prohibits issuing the fingerprint feature information to the control medium.

Furthermore, in addition to determining whether the terminal device has the right to download the fingerprint feature information, it may also determine whether the control medium has the right to download the fingerprint feature information. The cloud server issues the fingerprint feature information to the control medium only under the condition that the terminal equipment and the control medium both have the authority of downloading the fingerprint feature information, otherwise, the cloud server prohibits issuing the fingerprint feature information to the control medium.

Step S15: the control medium sends the fingerprint characteristic information to the target terminal equipment; the target terminal device is a first terminal device or a second terminal device.

The second terminal device can be an electronic device such as a mobile phone, a door lock or an entrance guard. The first terminal equipment and the second terminal equipment have fingerprint collection and fingerprint authentication functions. The first terminal device and the second terminal device are different electronic devices.

Based on the embodiment of the application, when the first terminal device needs to use the fingerprint feature information (for convenience of description, it is recorded as the first fingerprint feature information) to perform user identity authentication, and the first terminal device does not locally store the first fingerprint feature information (for example, a memory in the first terminal device for storing the first fingerprint feature information is replaced, or the first terminal device recovers factory settings, etc.), the first fingerprint feature information may be downloaded from the cloud server by the control medium, and the first fingerprint feature information may be sent to the first terminal device. Or,

when the second terminal device needs to use the first fingerprint feature information to perform identity authentication on the user, the control medium can also download the first fingerprint feature information from the cloud server and send the first fingerprint feature information to the second terminal device.

According to the information processing method, after the first terminal device generates the fingerprint characteristic information, the control medium sends the fingerprint characteristic file containing the fingerprint characteristic information to the cloud server for storage, so that after a storage used for storing the fingerprint characteristic information on the first terminal device is damaged and replaced by a new storage, the control medium can download the fingerprint characteristic information from the cloud terminal server and issue the fingerprint characteristic information to the first terminal device, user identity authentication can be achieved without the need that a user of the first terminal device enters a fingerprint again to form new fingerprint characteristic information, and convenience of the user is improved.

Similarly, when the second terminal device needs to use the first fingerprint feature information to perform identity authentication on the user, the control medium can also download the first fingerprint feature information from the cloud server and send the first fingerprint feature information to the second terminal device, so that the second terminal device does not need to input fingerprints for many times to generate new fingerprint feature information, and the convenience of the user is improved.

In addition, the communication connection between the cloud server and the terminal equipment is established through the control medium, low-speed data transmission can be carried out between the control medium and the terminal equipment, and high-speed data transmission can be carried out between the control medium and the cloud server through a high-speed network; on the other hand, in some application scenarios where the fingerprint feature information is updated frequently (for example, in a hotel, the updating frequency of the fingerprint feature information in the door lock of each room is relatively high), the administrator can perform unified management on the acquisition, storage and distribution of the fingerprint feature information through a control medium (for example, a computer located at the front desk), so that the operation of the administrator is facilitated.

In addition, after receiving the fingerprint feature information downloading request, the cloud server does not directly issue the fingerprint feature information to the control medium, but issues the fingerprint feature information to the control medium after judging that the control medium and/or the terminal device has the downloading authority, otherwise, does not issue the fingerprint feature information to the control medium, and further improves the security of the fingerprint feature information.

In an alternative embodiment, one implementation manner of controlling the medium to receive the first fingerprint feature file sent by the first terminal device may be as follows:

the control medium receives a first fingerprint feature file in a first ciphertext form sent by the first terminal device.

In the embodiment of the application, the first terminal device sends the first fingerprint feature file to the control medium in a ciphertext mode.

If the first terminal equipment uploads the fingerprint feature file to the control medium by dividing into a plurality of data packets, the first terminal equipment encrypts each data packet and uploads the data packet to the control medium. Or the first terminal equipment encrypts the first fingerprint feature file, divides the first fingerprint feature file in the form of the ciphertext into a plurality of data packets and transmits the data packets to the control medium.

The first terminal device may encrypt the first fingerprint feature file by using a private key of the first terminal device to obtain a first fingerprint feature file in a first ciphertext form.

In an optional embodiment, the first fingerprint feature file further includes an identification of the user; one implementation way for the control medium to send the second fingerprint feature file to the cloud server may be:

and the control medium sends the identification identifier of the first terminal device and the first fingerprint feature file in the first ciphertext form to the cloud server as a second fingerprint feature file. The technology for controlling the medium to obtain the identification of the first terminal device is mature, and detailed description is omitted in this application.

In another alternative embodiment, the first fingerprint profile does not include an identification of the user; one implementation way for the control medium to send the second fingerprint feature file to the cloud server may be:

and sending the identification mark of the first terminal equipment, the acquired identification mark of the user and the first fingerprint feature file in the first ciphertext form to the cloud server as a second fingerprint feature file.

The cloud server side stores a decryption algorithm corresponding to an encryption algorithm which is encrypted by the first terminal device through the private key of the first terminal device. After receiving the second fingerprint feature file, the cloud server may determine a private key corresponding to the identification identifier of the first terminal device by using the identification identifier of the first terminal device and a pre-stored correspondence between the device identification identifier and the private key, and decrypt the first fingerprint feature file in the second fingerprint feature file or the second fingerprint feature file through the private key to obtain the second fingerprint feature file in a plaintext form or the first fingerprint feature file in a plaintext form.

The cloud server stores the decrypted second fingerprint feature file in the form of a plaintext; alternatively, a fingerprint profile is stored which is composed of the first fingerprint profile in clear text and the identification of the user.

It should be noted that, in this embodiment, the storing of the fingerprint feature file in the plaintext form refers not to storing the feature file in the plaintext form, but to storing the decrypted fingerprint feature file. Specifically, when the fingerprint feature file obtained by decryption is stored, the fingerprint feature file obtained by decryption may be stored in a plaintext form, or the fingerprint feature file obtained by decryption may be stored in a ciphertext form.

When the fingerprint feature file in the plaintext form is stored, if the fingerprint feature file in the plaintext form is stored in the ciphertext form, the fingerprint feature file in the plaintext form can be encrypted into a fingerprint feature file in a second ciphertext form, and the fingerprint feature file in the second ciphertext form is stored, namely the fingerprint feature file is stored in the second ciphertext form, wherein the encryption key used for obtaining the first fingerprint feature file in the first ciphertext form is different from the encryption key used for obtaining the fingerprint feature file in the second ciphertext form. The encryption algorithm used for obtaining the fingerprint feature file in the second ciphertext form and the encryption algorithm used for obtaining the first fingerprint feature file in the first ciphertext form may be the same or different.

In the embodiment of the application, when the first terminal device sends the first fingerprint feature file to the control medium, the first fingerprint feature file is encrypted by using the private key of the first terminal device, so that the safety problem caused by the fact that the control medium is cracked by a third party and then the received first fingerprint feature file is maliciously stored and applied to other terminal devices is avoided.

In an optional embodiment, the fingerprint feature information download request sent by the control medium to the cloud server further carries an identification identifier of the target terminal device. The id of the target terminal device may be manually entered into the control medium by the user or selected by the user from a list of device ids provided by the control medium.

The fingerprint feature information corresponding to the identification identifier of the user and sent to the control medium by the cloud server is fingerprint feature information in a third ciphertext form, the fingerprint feature information in the third ciphertext form is obtained by determining a private key of the target terminal device by the cloud server according to the identification identifier of the target terminal device and a preset corresponding relationship between the device identification identifier and the private key, and encrypting the fingerprint feature information by using the private key.

The encryption algorithm used by the cloud server when encrypting the fingerprint feature file by using the private key of the target terminal device may be the same as or different from the encryption algorithm used by the first terminal device when encrypting the first fingerprint feature file by using the private key of the first terminal device. That is to say, the fingerprint feature information in the third ciphertext form may be the fingerprint feature information in the first ciphertext form, or may not be the fingerprint feature information in the first ciphertext form.

On the target terminal device side, a decryption algorithm corresponding to an encryption algorithm used by the cloud server when encrypting the fingerprint feature file with the private key of the target terminal device is stored.

And after receiving the fingerprint characteristic information in the third ciphertext form sent by the control medium, the target terminal equipment decrypts the fingerprint characteristic information in the third ciphertext form by using the private key of the target terminal equipment to obtain the fingerprint characteristic information in the plaintext form.

In an optional embodiment, the first fingerprint feature file may further include: the first verification information of the fingerprint characteristic information of the user is used for facilitating the cloud server to verify the fingerprint characteristic information of the user according to the first verification information before the second fingerprint characteristic file is stored, and the second fingerprint characteristic file is stored when the verification is passed.

If the second fingerprint feature file received by the cloud server is in a plaintext form, directly checking the fingerprint feature information in the second fingerprint feature file according to the first checking information; if the second fingerprint feature file received by the cloud server is the second fingerprint feature file in the form of the ciphertext or the first fingerprint feature file in the second fingerprint feature file is the first fingerprint feature file in the form of the ciphertext, the cloud server decrypts the second fingerprint feature file or the first fingerprint feature file first, and then verifies the fingerprint feature information in the second fingerprint feature file in the form of the plaintext or the first fingerprint feature file in the form of the plaintext obtained by decryption by using the first verification information. That is, the first verification information is calculated from the fingerprint feature information in the form of plaintext.

The cloud server stores the second fingerprint feature file in the plaintext form, before the second fingerprint feature file in the plaintext form is stored, the fingerprint feature information in the second fingerprint feature file in the plaintext form is firstly verified, the second fingerprint feature file in the plaintext form is stored only when the verification is passed, otherwise, the second fingerprint feature file is not stored, and the integrity and the effectiveness of the stored fingerprint feature file are ensured.

When the second fingerprint feature file in the plaintext form is stored, the second fingerprint feature file can be directly stored in the plaintext form or stored in the ciphertext form.

When the encrypted file is stored in the form of the ciphertext, the second fingerprint feature file can be encrypted by using the private key of the cloud server.

In an optional embodiment, after sending the fingerprint feature information download request to the cloud server, the controlling media may further include:

and the control medium receives second check information of the fingerprint characteristic information corresponding to the identification mark of the user, which is sent by the cloud server.

After receiving the fingerprint feature information downloading request, the cloud server calculates verification information (marked as second verification information) of the fingerprint feature information corresponding to the identification identifier of the user, and sends the fingerprint feature information corresponding to the identification identifier of the user to the control medium and also sends the second verification information of the fingerprint feature information to the control medium.

And the control medium sends the fingerprint characteristic information to the target terminal equipment and also sends second check information of the fingerprint characteristic information to the target terminal equipment, so that the target terminal checks the received fingerprint characteristic information by utilizing the second check information after receiving the fingerprint characteristic information.

Generally, the second check information is fingerprint information obtained by calculating fingerprint feature information in a plaintext form, after the target terminal device receives the fingerprint feature information, if the fingerprint feature information is a plaintext, the second check information can be directly used for checking the fingerprint feature information, if the fingerprint feature information is a ciphertext, the fingerprint feature information is decrypted first, and then the fingerprint feature information obtained by decryption is checked by using the second check information.

Another implementation flowchart of the information processing method provided by the present application is shown in fig. 2, and may include:

step S201: the control medium sends a fingerprint entry command to the first terminal device.

The fingerprint input instruction can be triggered and generated by the operation of the control medium on the control medium by a user of the control medium.

Step S202: the first terminal equipment responds to the fingerprint input command and starts a fingerprint input flow to collect fingerprints. And the user A presses the fingerprint sensor of the first terminal equipment by using the same finger for multiple times according to the operation prompt, and the fingerprint processing chip of the first terminal equipment extracts the characteristics of the fingerprint acquired by the fingerprint sensor for multiple times to obtain the fingerprint characteristic information of the user A.

Step S203: the first terminal device reports a recording completion command to the control medium.

Step S204: and the control medium issues a fingerprint feature file uploading command to the first terminal equipment.

The fingerprint file upload command may be triggered by a control medium user operating the control medium. Or the control medium can be automatically generated after receiving the recording completion command.

Step S205: the first terminal device responds to the fingerprint feature file uploading command, generates a fingerprint feature file and encrypts the fingerprint feature file, wherein the fingerprint feature file comprises fingerprint feature information of the user A and an identification mark (for convenience of description, the identification mark is recorded as a first user identification mark) of the user A. The first user identification is manually input into the first terminal device by a user or automatically acquired by the first terminal device.

The first terminal device encrypts the fingerprint feature file by using a private key of the first terminal device.

Optionally, before encrypting the fingerprint feature file, a check value of the fingerprint feature file, such as a CRC check value, may also be calculated. And after the check value is calculated, encrypting the fingerprint feature file.

Step S206: the first terminal equipment divides the fingerprint feature file in the form of the ciphertext into a plurality of data packets and sends the data packets to the control medium.

Optionally, if the check value is calculated, the first terminal device further sends the check value to the control medium. The check value may be sent to the control medium in a certain data packet or in a separate data packet.

Step S207: and the first terminal equipment sends a fingerprint feature file uploading ending command to the control medium after all the data packets are sent to the control medium.

Step S208: and after receiving the fingerprint feature file uploading finishing command, the control medium uploads the fingerprint feature file in the form of the ciphertext to the cloud server.

Step S209: and after receiving the fingerprint feature file in the ciphertext form, the cloud server decrypts the fingerprint feature file in the ciphertext form by using the private key of the first terminal device and stores the decrypted fingerprint feature file.

Optionally, if the control medium further uploads the check value, the cloud server decrypts the fingerprint characteristic file to obtain the fingerprint characteristic file, then verifies the fingerprint characteristic file obtained by decryption by using the check value, and stores the fingerprint characteristic file when the verification is passed.

When the cloud server stores the decrypted fingerprint feature file, the fingerprint feature information can be stored in a plaintext form or a ciphertext form. When the fingerprint characteristic information is stored in the form of the ciphertext, the private key of the cloud server can be used for encrypting the fingerprint characteristic information in the fingerprint characteristic file in the form of the plaintext, and the encrypted fingerprint characteristic information is stored in a manner of being associated with the identification mark of the user.

The above steps are a specific implementation process of the scheme for inputting fingerprints and uploading fingerprint feature files, and the process of issuing fingerprint feature information is described below.

Step S210: the control medium sends a fingerprint feature information downloading instruction to the cloud server, wherein the fingerprint feature information downloading instruction carries a first user identification (namely, an identification of the user A) and an identification of the first terminal device.

Step S211: after receiving the fingerprint feature information downloading instruction, the cloud server acquires corresponding fingerprint feature information (namely, the fingerprint feature information of the user A) according to the first user identification identifier. If the acquired fingerprint characteristic information is a ciphertext, the fingerprint characteristic information in the form of the ciphertext is decrypted by using the private key of the cloud server to obtain the fingerprint characteristic information in the form of a plaintext.

Step S214: and the cloud server transmits the fingerprint characteristic information in the form of the ciphertext to the control medium.

Optionally, if the cloud server further calculates the check value, the check value is issued to the control medium together.

Steps S210 to S216 describe a process of controlling the intermediary to download fingerprint feature information of the user a required by the first terminal device from the cloud server. The following describes a process of controlling the intermediary to download fingerprint feature information of the user a required by the second terminal device from the cloud server.

The first user identification is manually input into the first terminal device by a user or automatically acquired by the first terminal device.

Step S306: the first terminal equipment divides the fingerprint feature file in the form of the ciphertext into a plurality of data packets and sends the data packets to the control medium.

Step S307: and the first terminal equipment sends a fingerprint feature file uploading ending command to the control medium after all the data packets are sent to the control medium.

Step S308: and after receiving the fingerprint feature file uploading finishing command, the control medium uploads the fingerprint feature file in the form of the ciphertext to the cloud server.

Step S309: and after receiving the fingerprint feature file in the ciphertext form, the cloud server decrypts the fingerprint feature file in the ciphertext form and stores the decrypted fingerprint feature file.

The implementation process of steps S301 to S309 is the same as that of steps S201 to S209, and is not described in detail here.

Step S310: the control medium sends a fingerprint feature information downloading instruction to the cloud server, wherein the fingerprint feature information downloading instruction carries a first user identification (namely, an identification of the user A) and an identification of the second terminal device.

Step S311: after receiving the fingerprint feature information downloading instruction, the cloud server acquires corresponding fingerprint feature information (namely, the fingerprint feature information of the user A) according to the first user identification identifier.

Step S312: and the cloud server acquires the private key of the second terminal equipment by using the identification mark of the second terminal equipment.

Step S313: and the cloud server encrypts the fingerprint characteristic information in the form of plaintext by using the private key of the second terminal device.

Step S314: and the cloud server transmits the fingerprint characteristic information in the form of the ciphertext to the control medium.

Step S315: and the control medium transmits the fingerprint characteristic information in the form of the ciphertext to the second terminal equipment in a subpackaging manner.

Step S316: and the second terminal equipment decrypts and stores the fingerprint characteristic information in the form of the ciphertext by using the private key of the second terminal equipment.

Optionally, if the cloud server further issues a check value, the second terminal device further checks the fingerprint feature information obtained by decryption by using the check value.

If the memory card of the mobile phone of the user a has a problem and cannot be read, and a new memory card needs to be replaced, the fingerprint feature information stored before is lost after the new memory card is replaced. At this time, the user a does not need to re-enter the fingerprint so that the mobile phone can generate the fingerprint feature information, but directly downloads the fingerprint feature information uploaded before from the cloud server through the control medium.

Application scenario two

Before saving, the feature code of the identification mark of the user B can be calculated through a preset algorithm, and the feature code is saved in a manner of being associated with the fingerprint feature file in the form of the ciphertext.

In addition, after the user B enters the first room, if the user B is not satisfied with the first room, when the user B wants to change the room, the front desk worker only needs to download the fingerprint feature information of the user B again from the cloud server through the computer, and send the downloaded fingerprint feature information to the door lock of the second room newly allocated to the user B, and the user B does not need to re-enter the fingerprint in the front desk to form new fingerprint feature information. In particular, the method comprises the following steps of,

and the foreground staff sends a request for downloading the fingerprint characteristic information of the user B to the cloud server through computer operation, wherein the request carries the identity card number of the user B and the identification mark of the door lock of the second room distributed to the user B.

After receiving the request for downloading the fingerprint characteristic information of the user B, the cloud server searches the fingerprint characteristic file in the corresponding ciphertext form through the characteristic code of the identity card number of the user B, decrypts the fingerprint characteristic file in the searched ciphertext form, then searches the private key of the door lock of the second room by using the identification mark of the door lock of the second room, encrypts the fingerprint characteristic information in the fingerprint characteristic file obtained by decryption by using the private key of the door lock of the second room, and sends the fingerprint characteristic information in the ciphertext form to the computer.
