Description

Methods and equipment for identity recognition, business processing, and processing of biometric information

Technical Field

The present application relates to the field of network information security, and in particular to a method and device for identity recognition, business processing, and processing of biometric information.

Background Art

Biometrics is a new type of identification technology that combines biotechnology with information technology, utilizing human biological characteristics for identification and authentication. Human biological characteristics include DNA, fingerprints, facial features, and iris data. Because biometric information is unique and cannot be replicated, biometrics based on biometric information offer advantages such as security, confidentiality, and convenience.

As research into biometrics continues to deepen, it's being widely applied in business scenarios for user identification and authentication. For example, biometric sensors can be installed on devices like smart terminals and wearables to identify and authenticate users using the biometric information they collect.

Taking smart terminal devices as an example, when a user initiates a payment transaction through an application installed on the smart terminal device, first, the smart terminal device collects the user's biometric information (such as fingerprint information) through the biometric information sensor. Secondly, the smart terminal device sends the payment request carried by the collected user's biometric information to the server. The server verifies the user's identity based on the received user's biometric information, and responds to the payment request sent by the smart terminal device when the verification is successful.

However, there are at least the following problems in the existing process of authenticating user identities using biometric technology:

Since the user's biometric information is collected by the terminal device and sent to the server through the network, the server identifies and verifies the biometric information. In other words, if the terminal device sends illegal biometric information to the server, this not only increases the difficulty of identification for the server, but also cannot guarantee the security of subsequent business execution, thereby affecting the security of biometric recognition technology.

DETAILED DESCRIPTION

As people's research on biometric technology continues to deepen, biometric technology has been widely used in business scenarios where user identity identification and authentication are required. With the rapid development of science and technology, existing terminal devices have been equipped with biometric information sensors so that when users use terminal devices to perform business operations, the terminal devices collect the user's biometric information through the biometric information sensors and use biometric technology to identify and authenticate the user's identity.

In order to achieve the purpose of improving the security of biometric information, an embodiment of the present application provides a method and device for identity identification, business processing, and biometric information processing, wherein a terminal device receives a business processing request sent by a user, and the business processing request contains the user's identification information and the user's biometric information; the terminal device searches for the biometric information corresponding to the user's identification information from a biometric information database based on the user's identification information contained in the business processing request, and the biometric information database contains the user's identification information and the biometric information corresponding to the user's identification information; the terminal device determines whether the user's biometric information contained in the received business processing request is consistent with the biometric information corresponding to the found user's identification information, and identifies whether the user's identity is legal based on the judgment result.

In this way, when the terminal device receives a business processing request sent by the user, it identifies the user's identity based on the user's biometric information, thereby enhancing the security of the biometric technology and laying the foundation for the subsequent startup of the server to identify the user's identity. In addition, it also avoids the risk of the user's biometric information being easily illegally stolen during the process of being sent to the server through the communication network, effectively ensuring the security of the user's biometric information.

The terminal device described in the embodiments of the present application refers to a terminal device with a biometric information sensor. When a user performs business operations, the terminal device collects the user's biometric information through the biometric information sensor. The terminal device includes but is not limited to smartphones, computers and other terminal devices.

In the embodiment of the present application, the user's biometric information includes but is not limited to the user's DNA (English full name: Deoxyribonucleic acid; Chinese name: deoxyribonucleic acid) information, the user's fingerprint information, the user's iris information, the user's face information, the user's retinal information, the user's palm shape information, the user's vein information, the user's ear shape information, etc., which are not specifically limited here.

The following is a further detailed description of various embodiments of the present application in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present application, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present application without inventive effort are also within the scope of protection of this application.

Figure 1 is a flow chart of an identity recognition method provided by an embodiment of the present application, and the method is described as follows. The execution subject of the embodiment of the present application may be a terminal device.

Step 101: The terminal device receives a service processing request sent by a user.

The service processing request includes the user's identification information and the user's biometric information.

In step 101, when a user uses a terminal device to perform a service operation, the terminal device prompts the user to enter verification information to ensure the security of user information. The user can enter verification information by directly entering a verification code or by using a biometric sensor to enter the user's biometric information. In this embodiment of the application, only the collection of the user's biometric information is described.

Specifically, the terminal device collects the user's biometric information through the biometric information sensor and regards it as verification information input by the user.

For example: the terminal device collects the user's fingerprint information through the fingerprint information sensor on the terminal device; or the terminal device collects the user's face information through the face information sensor on the terminal device; or the terminal device collects the user's palm shape information through the palm shape information sensor on the terminal device.

After the user enters their biometric information, the user is triggered to send a service request to the terminal device. The terminal device receives the service request, which includes the user's identification information and biometric information. The terminal device then identifies and authenticates the user based on the received biometric information.

The following uses payment services as an example. In a payment service scenario, when a user initiates a payment service through the payment software on a terminal device, the terminal device's payment software prompts the user to enter payment verification information. This payment verification information is limited to the user's biometric information. At this point, the terminal device collects the user's biometric information through a biometric information sensor to complete the user's biometric information input. After the user enters the payment verification information, the user is triggered to initiate a payment service processing request to the terminal device. This payment service processing request includes the user's identification information and the user's biometric information.

Step 102: The terminal device searches for biometric information corresponding to the user identification information from a biometric information database based on the user identification information included in the service processing request.

The biometric information database includes user identification information and biometric information corresponding to the user identification information.

In step 102, when the terminal device receives a business processing request sent by the user, it determines the user's identification information and the user's biometric information contained in the business processing request, and uses the user's identification information to search for biometric information corresponding to the user's identification information in the biometric information database, so that the terminal device can identify the user's identity based on the biometric information corresponding to the found user's identification information.

Since the biometric information database pre-stores the user's identification information and the user's biometric information, when the terminal device needs to identify the user's identity, it can use the user's identification information to search the biometric information database for the biometric information corresponding to the user's identification information.

Specifically, the terminal device stores the user's biometric information in the biometric information database in the following manner:

Step 1: The terminal device receives a registration request sent by the user, and obtains the user's biometric information and the user's identification information contained in the registration request.

Before using the application software on the terminal device, the user needs to register on the application software, that is, send a registration request. Generally, the registration request contains the user's identification information and the user's biometric information. When the terminal device receives the registration request sent by the user, it can obtain the user's identification information and the user's biometric information from the registration request, and send the user's identification information and the user's biometric information to the server corresponding to the application software to complete the user's registration in the application software.

For example, if a user wants to use a payment application on a terminal device, they must register with the payment application. On the payment application's registration page, the user enters registration information, including identification and biometric information, and initiates a registration request. The terminal device then receives the registration request and obtains the user's identification and biometric information from the request. Furthermore, the terminal device encrypts the user's identification and biometric information and sends it to the payment application's server, completing the user's registration with the payment application.

Step 2: The terminal device establishes a correspondence between the user's identification information and the user's biometric information, and stores the correspondence in the biometric information database.

After obtaining the user's identification information and the user's biological and characteristic information, the terminal device establishes a correspondence between the user's identification information and the user's biometric information, and stores the correspondence between the user's identification information and the user's biometric information in the terminal device's biometric information database, so that the terminal device can search for biometric information corresponding to the user's identification information in the biometric information database based on the user's identification information.

Optionally, the method further includes:

When the terminal device obtains the biometric information of the user included in the registration request, it calculates the attribute value of the biometric information of the user using a preset algorithm.

Specifically, after the terminal device obtains the user's biometric information contained in the user's registration information, the terminal calculates the attribute value of the user's biometric information based on the user's biometric information according to a preset algorithm. For example, the terminal device uses the Rijndael algorithm (key generation algorithm) to calculate the attribute value of the user's biometric information; the terminal device uses the Hash function (hash function) algorithm to calculate the attribute value of the user's biometric information; the terminal device can also use other computer algorithms to calculate the attribute value of the user's biometric information. The embodiment of the present application does not specifically limit the algorithm adopted by the terminal device.

After calculating and obtaining the attribute value of the user's biometric information, the terminal device establishes a correspondence between the user's identification information, the user's biometric information, and the attribute value of the user's biometric information.

The terminal device stores the correspondence between the user's identification information, the user's biometric information, and the attribute value of the user's biometric information in the biometric information database. Thus, in the biometric information database, the terminal device can search for the user's biometric information corresponding to the user's identification information and/or the attribute value of the user's biometric information corresponding to the user's identification information based on the user's identification information and the correspondence.

Optionally, the terminal device may update the user's biometric information stored in the biometric information database.

Specifically, the biometric information stored in the biometric information database in the terminal device may include the biometric information of all users who use the terminal device. That is, before the terminal device stores the biometric information contained in the registration request sent by the user in the biometric information database, the terminal device queries whether the biometric information corresponding to the user's identification information is stored in the biometric information database. If it is determined according to the query result that the biometric information of the user has been stored in the biometric information database, then the terminal device stores the biometric information contained in the registration request sent by the user in the biometric information database to update the biometric information of the user already stored in the biometric information database.

It should be noted that before updating the biometric information of the user stored in the biometric information database, the terminal device prompts the user to enter verification information for verifying the user's identity, such as the user's verification email, user password, and the user's biometric information pre-stored in the biometric information database. After verifying the user's legal identity based on the verification information entered by the user, the terminal device updates the stored biometric information of the user with the received biometric information of the user, and stores the received identification information of the user, the biometric information of the user, and the attribute values corresponding to the biometric information of the user in the biometric information database.

When the terminal device finds that the biometric information of the user corresponding to the identification information of the user is not stored in the biometric information database, the terminal device stores the identification information of the user, the biometric information of the user, and the attribute value corresponding to the biometric information of the user contained in the received registration request of the user in the biometric information database. That is, the terminal device adds the biometric information of the user, the identification information of the user, and the attribute value of the biometric information of the user to the biometric information database.

The biometric information in the biometric information database is updated through the terminal device. Once the user's biometric information is damaged or lost, the biometric information database can promptly update the original biometric information of the user with the new biometric information of the user, thereby ensuring the validity of the biometric information in the biometric information database. At the same time, it can also ensure that the terminal device searches the biometric information database for the user's biometric information corresponding to the user's identification information based on the user's identification information contained in the business processing request sent by the user.

Step 103: The terminal device determines whether the biometric information of the user included in the received service processing request is consistent with the biometric information corresponding to the found identification information of the user, and identifies whether the identity of the user is legal based on the determination result.

In step 103, after receiving the user's business processing request, the terminal device can determine the biometric information corresponding to the user's identification information in the biometric information database based on the user's identification information contained in the business processing request, and the terminal device identifies the user's identity based on the found biometric information.

Specifically, since the biometric information database stores the correspondence between the user's identification information, the user's biometric information and the attribute value of the user's biometric information, or stores the correspondence between the user's identification information and the user's biometric information, the terminal device can search for the biometric information corresponding to the user's identification information in the biometric information database based on the user's identification information and the correspondence.

Then, the terminal device determines whether the received biometric information of the user is consistent with the biometric information corresponding to the found identification information of the user, and identifies whether the identity of the user is legal based on the determination result, including:

Assuming that the biometric information database stores the correspondence between the user's identification information and the user's biometric information, the terminal device searches the biometric information database for the user's biometric information corresponding to the user's identification information based on the user's identification information. At this time, when the terminal device determines that the user's biometric information included in the received service processing request is consistent with the biometric information corresponding to the searched user's identification information, it indicates that the user performing the service operation is the same person as the previously registered user, and the identification of the user's identity is legal;

When the terminal device determines that the biometric information of the user contained in the received business processing request is inconsistent with the biometric information corresponding to the found identification information of the user, it means that the user performing the business operation and the previously registered user are not the same person, and the identification of the user's identity is illegal.

Assuming that a biometric information database stores a correspondence between the user's identification information, the user's biometric information, and the attribute value corresponding to the user's biometric information, the terminal device searches the biometric information database for the attribute value of the user's biometric information corresponding to the user's identification information based on the user's identification information. At this time, the terminal device calculates the attribute value of the received user's biometric information using a preset algorithm. At this time, when the terminal device determines that the attribute value of the user's biometric information contained in the received service processing request is consistent with the attribute value of the biometric information corresponding to the found user's identification information, it recognizes that the user's identity is legitimate.

When the terminal device determines that the attribute value of the user's biometric information included in the received service processing request is inconsistent with the attribute value of the biometric information corresponding to the found identification information of the user, the terminal device identifies that the identity of the user is illegal.

Optionally, the method further includes:

When the terminal device recognizes that the identity of the user is legitimate, it sends the attribute value and the identification information of the user to the server in a service processing request.

It should be noted that in the embodiment of the present application, the terminal device can determine the attribute value of the biometric information corresponding to the user's identification information by searching, or it can determine the attribute value of the biometric information corresponding to the user's identification information by calculating the user's biometric information using a preset algorithm. No specific limitation is made here.

It should be noted that after the terminal device recognizes that the identity of the user is legitimate, it sends a business processing request to the server. The business processing request here is the same as the business represented by the business processing request sent by the user in step 101, but the content included is different. The business processing request here includes the user's identification information, the user's biometric information and the attribute value of the user's biometric information. The business processing request sent by the user in step 101 includes the user's identification information and the user's biometric information.

Optionally, in order to ensure the security of the attribute values of the user's biometric information during transmission to the server, the terminal device performs an encryption operation on the attribute values of the user's biometric information and the user's identification information, and sends the encrypted attribute values of the biometric information and the user's identification information to the server.

Specifically, the terminal device encrypts the user identification information and the attribute value corresponding to the determined biometric information of the user to obtain an encryption result;

The terminal device sends the service processing request carrying the encryption result to the server.

It should be noted that the terminal device and the server obtain their respective private keys and public keys through negotiation. The private keys of the terminal device and the server are confidential, and the public keys of the terminal device and the server are public, and the public keys and private keys of the terminal device/the server are matched in pairs.

When the terminal device sends the attribute values of the user's biometric information and the user's identification information to the server, it encrypts the sent attribute values of the user's biometric information and the user's identification information using the server's public key to obtain an encrypted result, and sends the encrypted result to the server. The server decrypts the received encrypted result using its own private key. Because the server's private key is kept confidential, only the server can decrypt the encrypted result sent by the terminal device, thereby ensuring the security of the attribute values of the user's biometric information sent by the terminal device.

To further ensure the security of the attribute values of the user's biometric information, after the terminal device encrypts the sent encryption result using the server's public key, the terminal device can also use its own private key to encrypt the sent attribute values of the user's biometric information a second time. In this way, when the server receives the encrypted result, it first decrypts the received encryption result using the terminal device's public key. If the server decrypts successfully, it indicates that the encrypted result received by the server was sent by the terminal device, that is, the attribute values of the user's biometric information sent by the terminal device have not been tampered with during the transmission process. The server then decrypts the encrypted result using its own private key to obtain the attribute values of the user's biometric information and user identification information sent by the terminal device.

In an embodiment of the present application, the terminal device encrypts the attribute value of the biometric information corresponding to the user's identification information and the user's identification information, and sends it to the server, which not only ensures the security of the attribute value of the biometric information corresponding to the user's identification information during the transmission process, but also, compared with the prior art in which the terminal device directly sends the user's biometric information to the server, the terminal device in the embodiment of the present application sends the attribute value of the biometric information corresponding to the user's identification information to the server, avoiding the risk of the user's biometric information being easily obtained by others during the transmission process, thereby improving the security of the user's biometric information.

Optionally, when the terminal device identifies that the identity of the user is illegal, it returns the identity identification result to the user, refuses to respond to the user's business processing request, and prompts the user that the identity identification failed. For example, the terminal device prompts the user to log in again, the terminal device displays an alarm message and prompts that the user's identity is illegal, the terminal device directly returns to the user's business operation interface, etc. There is no specific limitation on the content and form of the identity identification result returned by the terminal device to the user.

Through the solution described in the embodiment of the present application, when the terminal device receives a business processing request sent by the user, it identifies the user's identity based on the user's biometric information, thereby enhancing the security of the biometric technology and laying the foundation for the subsequent startup of the server to identify the user's identity. In addition, it also avoids the risk of the user's biometric information being easily illegally stolen during the process of being sent to the server through the communication network, effectively ensuring the security of the user's biometric information.

Figure 2 is a flow chart of a service processing method provided by an embodiment of the present application, and the method is described as follows. The execution subject of the embodiment of the present application may be a server.

Step 201: The server receives a service processing request sent by a terminal device.

The service processing request includes the attribute value corresponding to the user's biometric information and the user's identification information.

In step 201, the server receives a service processing request sent by the terminal device, where the service processing request carries the user's identification information and an encrypted result of an attribute value of biometric information corresponding to the user's identification information.

After the server receives the business processing request sent by the terminal device, the server decrypts the attribute values of the encrypted user's biometric information and the user's identification information contained in the business processing request, and obtains the attribute values of the user's biometric information and the user's identification information contained in the business processing request through the decryption operation.

The server decrypts the encrypted attribute values of the user's biometric information and the user's identification information through the decryption method in the first embodiment provided in this application, which will not be repeated here.

After decrypting the encryption result, the server obtains the attribute value of the user's biometric information and the user's identification information contained in the service processing request sent by the terminal device.

Step 202: The server searches a biometric database for an attribute value of the biometric feature information corresponding to the user's identification information based on the user's identification information included in the received service processing request.

The biometric database contains the identification information of the user and the attribute value of the biometric information corresponding to the identification information of the user.

In step 202, when the server receives the business processing request sent by the terminal device, it determines the user's identification information and the attribute value of the user's biometric information contained in the business processing request, and uses the user's identification information to search for the attribute value of the biometric information corresponding to the user's identification information in the biometric database, so that the server can verify the user's identity based on the attribute value of the biometric information corresponding to the user's identification information found.

Since the biometric database pre-stores the user's identification information and the attribute values of the user's biometric information, when the server needs to verify the user's identity, it can use the user's identification information to search the biometric database for the attribute values of the biometric information corresponding to the user's identification information.

Specifically, the server stores the attribute value of the biometric information corresponding to the identification information of the user in the biometric recognition database in the following manner:

Step 1: The server receives the user information sent by the terminal device.

Among them, the user information is sent by the terminal device after encrypting the user's identification information and the attribute values of the user's biometric information contained in the registration request sent by the user, and the user information contains the user's identification information and the attribute values of the user's biometric information.

When the terminal device receives the registration request sent by the user, it obtains the identification information and biometric information of the user contained in the registration request, and determines the attribute value of the user's biometric information based on the biometric information of the user, and then encrypts the attribute value of the user's biometric information and the identification information of the user, and sends the encrypted attribute value of the user's biometric information and the identification information of the user to the server, so that the server receives the encrypted identification information and biometric information of the user sent by the terminal device.

Step 2: The server obtains the attribute value of the user's biometric information and the user's identification information contained in the user information through a decryption operation.

The server uses the public key of the terminal device to decrypt the encrypted user information and verify whether the business processing request is sent by the terminal device. After the verification is passed, the server determines that the registration processing request carrying the encryption result has not been tampered with during the transmission process. The server uses its own public key to decrypt the encryption for the second time, and the server obtains the attribute value of the user's biometric information and the user's identification information.

Step 3: The server establishes a correspondence between the user's identification information and the attribute value of the user's biometric information, and stores the correspondence in the biometric recognition database.

After obtaining the attribute value of the user's biometric information and the user's identification information, the server establishes a correspondence between the user's identification information and the attribute value of the user's biometric information, and stores the correspondence between the user's identification information and the attribute value of the user's biometric information in the biometric recognition database in the server.

In this way, in the biometric database, the server can find the attribute value of the user's biometric information corresponding to the user's identification information based on the user's identification information and the above-mentioned correspondence.

Optionally, when the server receives the user's identification information and the attribute value of the user's biometric information sent by the terminal device, it first determines whether the attribute value of the user's biometric information corresponding to the user's identification information has been stored in the biometric database; secondly, when it is determined that the attribute value of the user's biometric information corresponding to the user's identification information has been stored, it can use the received attribute value of the user's biometric information to update the stored attribute value of the user's biometric information; when it is determined that the attribute value of the user's biometric information corresponding to the user's identification information has not been stored, it can store the received attribute value of the user's biometric information in the biometric database to facilitate subsequent identification of the user's identity.

Step 203: When the server determines that the attribute value corresponding to the user's biometric information contained in the received service processing request is the same as the attribute value of the biometric information corresponding to the found user identification information, the server responds to the service processing request.

Specifically, since the biometric database stores the correspondence between the user's identification information and the user's biometric information attribute value, the server can search the biometric database for the attribute value of the biometric information corresponding to the user's identification information based on the user's identification information and the correspondence.

Then, after the server finds the attribute value of the user's biometric information corresponding to the user's identification information in the biometric database, the server compares the received attribute value of the user's biometric information with the attribute value of the biometric information corresponding to the found user's identification information, including:

The server determines that the attribute value of the received biometric information of the user is the same as the attribute value of the found biometric information of the user, indicating that the user performing the service operation and the previously registered user are the same person. The server verifies the legitimacy of the user's identity and responds to the service processing request sent by the terminal device.

The server determines that the attribute value of the received biometric information of the user is different from the attribute value of the biometric information of the user found, indicating that the user performing the business operation and the previously registered user are not the same person. The server verifies that the identity of the user is illegal, and the server refuses to respond to the business processing request sent by the terminal device.

Optionally, after the server verifies that the identity of the user is illegal, it prompts the terminal device that the identity of the user is illegal and returns an alarm message, indicating that the service processing request has failed. The content and form of the alarm message returned by the server are not specifically limited here.

Step 301: The terminal device receives the user's identification information and the user's biometric information sent by the user.

In step 301, the user identification information and the user biometric information sent by the user may be sent by the user when registering the application software, or may be sent by the user when performing other operations, which are not specifically limited here.

The terminal device receives the user's identification information and the user's biometric information sent by the user, so that the terminal device processes the user's biometric information.

Step 302: The terminal device calculates the attribute value of the user's biometric information using a preset algorithm based on the user's biometric information.

The terminal device calculates the attribute value of the user's biometric information based on the user's biometric information using the preset algorithm in the first embodiment provided in this application, which will not be repeated here.

Optionally, after obtaining the attribute value of the user's biometric information, the terminal device encrypts the user's identification information and the attribute value of the user's biometric information to obtain an encryption result, and the terminal device sends the encryption result to the server.

The terminal device in the embodiment of the present application uses the encryption method in the first embodiment provided in the present application to encrypt the attribute values of the user's biometric information and the user's identification information, which will not be repeated here.

Step 303: The terminal device establishes a correspondence between the user's identification information, the user's biometric information, and the attribute value of the user's biometric information, and stores the correspondence in the biometric information database.

In step 303, before the terminal device stores the correspondence between the user's identification information, the user's biometric information and the attribute value of the user's biometric information in the biometric information database, the terminal device queries whether the user's biometric information exists in the biometric information database. If the user's biometric information may have been stored in the biometric information database, the terminal device stores the biometric information sent by the user in the biometric information database to update the user's biometric information already stored in the biometric information database.

Specifically, the terminal device sends a query request to the biometric information database, wherein the query request includes the identification information of the user;

The terminal device receives the query result returned by the biometric information database;

The terminal device determines, based on the query result, that the biometric information of the user corresponding to the identification information of the user has been stored in the biometric information database, and uses the received biometric information of the user to update the biometric information of the user corresponding to the identification information of the user stored in the biometric information database.

The updating method of the biometric information database here is the same as the updating method of the biometric information database in the first embodiment provided in this application, and will not be described again.

When the terminal device determines that the biometric information of the user is not stored in the biometric information database, the terminal device determines the attribute value of the received biometric information and adds a correspondence between the biometric information of the user, the identification information of the user and the attribute value of the biometric information of the user to the biometric information database.

Step 401: The server receives user information sent by the terminal device.

Among them, the user information is sent after the terminal device encrypts the user's identification information and the attribute value of the user's biometric information when obtaining the attribute value of the user's biometric information. The user information contains the user's identification information and the attribute value of the user's biometric information.

Step 402: The server obtains the attribute value of the user's biometric information and the user's identification information contained in the user information through a decryption operation.

The server decrypts the encrypted attribute values of the user's biometric information and the user's identification information through the decryption method in the first embodiment provided in this application, which will not be repeated here.

After decrypting the user information, the server obtains the attribute value of the user's biometric information and the user's identification information contained in the user information.

Step 403: The server establishes a correspondence between the user's identification information and the attribute value of the user's biometric information, and stores the correspondence in the biometric recognition database.

After obtaining the attribute value of the user's biometric information and the user's identification information, the server establishes a correspondence between the user's identification information and the attribute value of the user's biometric information, and stores the user's identification information and the attribute value of the user's biometric information in the biometric recognition database in the server.

Optionally, the server may also update the biometric information of the user stored in the biometric database. The specific implementation method of the update is the same as that used in step 202 in Figure 2 and will not be repeated here.
