Description

Technical Field

[0001] The present invention relates to the technical field of image processing, and in particular to a method for using an electronic signature online. Background Art

[0002] An electronic signature is a digital seal document used to guarantee the authenticity and integrity of a document. With the continued development of the paperless office concept, the application scope of electronic signatures is also expanding. Electronic signatures are widely used in contract signing, document approval, and email authentication.

[0003] In existing technology, a seal image is pre-synthesized with the authentication certificate. When a signature request is received, the document is signed directly using the synthesized electronic signature. However, this approach may require a new electronic signature to be created after the authentication certificate expires, limiting user flexibility in using electronic signatures. Furthermore, if the pre-synthesized electronic signature is lost, it could be misused, making the security of the electronic signature impossible to guarantee. Summary of the Invention

[0004] The present invention provides a method for using an electronic signature online, which improves the flexibility and security of using the signature.

[0037] Example 1

[0038] Figure 1This is a flowchart of a method for using an electronic signature online provided by the first embodiment of the present invention. This embodiment can be applied to the case where, upon receiving a request to use an electronic signature, the target electronic signature can be synthesized using an electronic seal, first authentication information, and a certification certificate to perform document signing processing, thereby meeting the signature usage requirements of different business scenarios. This method can be executed by an online electronic signature device, which can be implemented in the form of hardware and / or software, and can be configured in electronic devices such as mobile phones, computers, or servers. Figure 1 As shown, the method includes:

[0039] S110. When receiving an electronic signature use request, obtain user information and service applicable type information carried in the electronic signature use request.

[0040] The electronic signature request may be initiated by a client and require the use of an electronic signature. Optionally, the electronic signature request may be generated in response to a user triggering an action on a corresponding interface. User information may be used to identify the user. User information may be used to determine whether the user has permission to use the electronic signature corresponding to the electronic signature request. Service applicability information may be used to identify the service type for which the electronic signature corresponding to the electronic signature request is intended.

[0041] Specifically, when receiving the electronic signature use request sent by the client, the electronic signature use request is parsed and processed to determine the user information and service applicable type information carried in the electronic signature use request.

[0042] S120: Display at least one usable electronic seal based on the authority information and business applicable type information corresponding to the user information.

[0043] Among them, the usable electronic seal is based on a seal in at least one pre-made selectable electronic seal, and the selectable electronic seal is composed of the elements required for the pre-made seal. The authority information corresponding to the user information can be understood as the authority of the electronic seal corresponding to the user information. In other words, the authority information corresponding to the user information can be used to characterize whether the current user has the authority to obtain an electronic seal that matches the business applicable type information. The elements required for the seal can be understood as the elements contained in the selectable electronic seal. Optionally, the elements required for the seal include element information such as the double rings, upper chord patterns, lower chord patterns, horizontal patterns, middle graphics, and text in the seal. The usable electronic seal can be an electronic seal selected from at least one selectable electronic seal, which is compatible with the authority information and business applicable type information.

[0044] Specifically, the authorization information corresponding to the user information is determined. The authorization information is verified to determine whether the current user has the authority to use an electronic seal that matches the service applicable type information. If the verification passes, at least one usable electronic seal that matches the service applicable type information is retrieved for the user to select.

[0045] For example, see Figure 2 , can be achieved through Figure 2 The seal generation unit in the system determines at least one usable electronic seal. The seal generation unit is used to determine at least one usable electronic seal. The seal generation unit includes: an authority verification operator, a stamp selection operator, and a string code synthesis operator.

[0046] Upon receiving a user-initiated request to use an electronic signature, the request is parsed to determine the user information and business applicability information. The permission verification operator in the seal generation unit verifies the permission information corresponding to the user information to determine whether the user has permission to use an electronic seal that matches the business applicability information. If the verification passes, the seal generation unit uses the stamp selection operator to retrieve and display at least one usable electronic seal that matches the business applicability information. If the verification fails, the verification result is returned to the user.

[0047] In an embodiment of the present invention, a method for displaying at least one usable electronic seal based on authority information and business applicability type information may be: determining whether the selectable electronic seal is a usable electronic seal based on the user authority level configured for the at least one selectable electronic seal and the user authority corresponding to the user information; and determining whether the selectable electronic seal is a usable electronic seal based on the business applicability scope authority and business applicability type information configured for the at least one selectable electronic seal; if all the selectable electronic seals are usable electronic seals, the selectable electronic seal will be treated as a usable electronic seal and displayed.

[0048] Among them, for at least one pre-made optional electronic seal, each optional electronic seal is correspondingly configured with a user authority level and business applicable scope authority. The user authority level can be used to characterize the user level that can use the optional electronic seal. Optionally, the user authority level can include ordinary users and advanced users. For example, if the user authority corresponding to the user information is ordinary user, and the user authority level corresponding to the current optional electronic seal is advanced user, it means that the user authority and the user authority level of the current optional electronic seal do not match, and the current optional electronic seal cannot be used as a displayed and usable electronic seal.

[0049] The business scope permission can be used to indicate the range of business types that can be selected for electronic seals. For example, the business scope permission for the current selectable electronic seals can be: Business Type A, Business Type B, and Business Type C. If the business type information carried in the electronic signature use request is Business Type C, it means that the business scope permission for the current selectable electronic seal matches the business type information, and the current selectable electronic seal can be used as a displayed electronic seal.

[0050] Specifically, based on the user authority level pre-configured for at least one selectable electronic seal and the user authority corresponding to the user information carried in the electronic signature use request, determine whether the user authority matches the user authority level. If the user authority meets the user authority level, then determine that the selectable electronic seal can be used as an usable electronic seal. Correspondingly, based on the business applicability scope authority pre-configured for at least one selectable electronic seal and the business applicability type information carried in the electronic signature use request, determine whether the business applicability type information matches the business applicability scope authority. If the business applicability type information meets the business applicability scope authority, then determine that the selectable electronic seal can be used as an usable electronic seal. If the selectable electronic seal can be used as an usable electronic seal in both of the above two cases, then the selectable electronic seal will be used as an usable electronic seal. Correspondingly, if there is at least one of the above cases, the selectable electronic seal cannot be used as a usable electronic seal, then continue to determine whether the next selectable electronic seal can be used as a usable electronic seal.

[0051] S130: In response to a triggering operation on any one of at least one usable electronic seal, add first authentication information corresponding to the service applicable type information to a preset position of the triggered usable electronic seal.

[0052] The triggering operation may be a user-triggered operation to select the electronic seal. The preset location may be a pre-set location for adding the first authentication information. The first authentication information may be used to verify the authority to use and the authenticity of the electronic seal, thereby preventing forgery or misuse of the electronic seal. Optionally, the first authentication information may be a serial code corresponding to the service applicable type information. This serial code may be used to verify the business transaction information corresponding to the electronic signature use request.

[0053] Specifically, in response to a triggering operation on any usable electronic seal, the triggered usable electronic seal is determined, first authentication information corresponding to the service applicable type information is generated, and the first authentication information is added to a preset position of the triggered usable electronic seal to obtain the usable electronic seal to which the first authentication information is added.

[0054] Exemplarily, in combination with the above example, the first authentication information is used as a string code for explanation. After at least one usable electronic seal is determined by the stamp selection operator of the stamp generation unit, the at least one usable electronic seal can be displayed on the target interface for user selection. When it is detected that the user triggers one of the at least one usable electronic seal, the triggered usable electronic seal is determined. At the same time, the string code synthesis operator of the stamp generation unit is called to synthesize the string code at the specified position of the triggered usable electronic seal to obtain a business seal image, that is, the usable electronic seal to which the first authentication information has been added. Optionally, the business transaction information corresponding to the electronic signature use request can be verified subsequently through the string code.

[0055] In an embodiment of the present invention, the method of adding the first authentication information to the triggered usable electronic seal can be: determining the first authentication information based on the business applicability type information and the business processing data information in the electronic signature usage request, and adding the first authentication information to the preset position of the triggered usable electronic seal.

[0056] The business processing data information can be understood as the business data corresponding to the electronic signature carried in the electronic signature use request. Optionally, the business processing data information can be the business data related to the use of the electronic signature processed before sending the electronic signature use request.

[0057] Specifically, first authentication information is generated based on the business applicable type information and the business processing data information carried by the electronic signature usage request, and the first authentication information is added to the preset position of the triggered usable electronic seal to obtain a usable electronic seal with the first authentication information added.

[0058] S140: Determine a target electronic signature based on the triggered authentication certificate that can use the electronic seal and the usable electronic seal to which the first authentication information has been added.

[0059] The content corresponding to the authentication certificate is the second authentication information of the target electronic signature. The second authentication information can be used to verify the authority and authenticity of the target electronic signature. Optionally, the second authentication information can be a digital signature corresponding to the content of the authentication certificate. The authentication certificate can be a certificate selected based on the business applicability type information and user information in the electronic signature use request. Optionally, based on the business applicability type information and user information, the authentication certificate is determined to be a user-level certificate or an enterprise-level certificate. The target electronic signature can be a usable electronic seal with the first authentication information and the second authentication information added.

[0060] Specifically, based on the business applicability type information and user information in the electronic signature request, the type of authentication certificate is determined, and a corresponding authentication certificate is selected. Second authentication information is determined based on the content of the authentication certificate. The second authentication information is added to the preset position of the usable electronic seal to which the first authentication information has been added, thereby obtaining a usable electronic seal to which the first authentication information and the second authentication information have been added. The usable electronic seal to which the first authentication information and the second authentication information have been added is determined as the target electronic signature, so that the document to be signed is electronically signed based on the target electronic signature.

[0061] In an embodiment of the present invention, the method for determining the target electronic signature can be: determining the authentication certificate of the target certificate type based on the business applicability type information and user information in the electronic signature usage request; converting the authentication certificate into second authentication information, and adding the second authentication information to the usable electronic seal to which the first authentication information has been added to obtain the target electronic signature.

[0062] The target certificate type may be a user-level certificate type or an enterprise-level certificate type.

[0063] Specifically, the target certificate type is determined based on the service applicable type information and user information in the electronic signature request, and the authentication certificate corresponding to the target certificate type is retrieved. The content in the authentication certificate is converted into second authentication information, and the second authentication information is added to the preset location of the usable electronic seal to which the first authentication information has been added, thereby obtaining the target electronic signature.

[0064] For example, in conjunction with the above examples, see Figure 3 After the seal generation unit generates a business seal image (a usable electronic seal with the first authentication information added), the signature generation unit can generate the corresponding target electronic signature. The signature generation unit includes a file processing operator, a certificate selection operator set, and a signature generation operator.

[0065] After generating the business seal image, the certificate selection operator can be used to determine the authentication certificate of the target certificate type corresponding to the business applicable type information and user information, such as determining the enterprise-level authentication certificate, so that after receiving the document to be signed, the authentication certificate can be synthesized at the specified position of the document to be signed.

[0066] S150: Perform electronic signature processing on the received document to be signed based on the target electronic signature.

[0067] Among them, the document to be signed can be understood as the document that currently needs to be signed.

[0068] Specifically, after receiving a document to be signed, a file format verification process can be performed on the document to be signed. If the file format of the document to be signed falls within a preset file format range, the file format verification is determined to have passed, and the document to be signed can be electronically signed based on the target electronic signature. Conversely, if the file format of the document to be signed does not fall within the preset file format range, the file format verification fails, and the document to be signed cannot be electronically signed. Optionally, the preset file format range may include file formats such as PDF.

[0069] Exemplarily, in combination with the above example, after the signature generation unit receives the file to be signed uploaded by the user, the file format verification processing can be performed on the file to be signed based on the file processing operator of the signature generation unit to obtain a verification result. If the verification result is that the file verification passes, the business seal image and the certification certificate can be synthesized based on the signature generation unit to obtain a target electronic signature with a digital signature. Among them, the digital signature corresponds to the second authentication information mentioned in the above embodiment. The target electronic signature is synthesized at the specified position of the file to be signed by the signature generation unit to obtain a signature file. The signature file is exported by the file processing operator of the signature generation unit so that the user can obtain the signature file.

[0070] In an embodiment of the present invention, the method of signing a document to be signed using a target electronic signature may be: receiving the document to be signed and indicating the electronic signature area to display the target electronic signature in the electronic signature area; or receiving the document to be signed and determining the signature area in the document to be signed to display the target electronic signature in the signature area.

[0071] The electronic signature area can be a pre-set area in the document to be signed for adding a target electronic signature. The signature area in the document to be signed can be an area determined after image recognition of the document to be signed for adding a target electronic signature.

[0072] Specifically, after receiving a document to be signed, the target electronic signature can be displayed in the electronic signature area pre-set in the document to be signed. Alternatively, after receiving the document to be signed, image recognition processing can be performed on the document to be signed to determine the signature area corresponding to the document to be signed, and the target electronic signature can be displayed in the signature area, thereby completing the electronic signature processing of the document to be signed and obtaining a signed document.

[0073] The technical solution of this embodiment obtains the user information and business applicability information contained in the electronic signature request upon receiving it. Based on the permission information and business applicability information corresponding to the user information, at least one usable electronic seal is displayed. Based on this, at least one usable electronic seal that matches the permission information and business applicability information can be displayed. In response to a triggering operation on any usable electronic seal, first authentication information corresponding to the business applicability information is added to a preset position of the triggered usable electronic seal, facilitating subsequent verification of the current business transaction based on the first authentication information in the electronic signature. Based on the authentication certificate of the triggered usable electronic seal and the usable electronic seal to which the first authentication information has been added, a target electronic signature is determined, and the received document to be signed is electronically signed based on the target electronic signature. By synthesizing the usable electronic seal, the first authentication information, and the authentication certificate upon receiving the electronic signature request, the target electronic signature is obtained, thereby resolving the issues of low flexibility and security associated with pre-generated electronic signatures. By determining the appropriate first authentication information and certification certificate for each application scenario, the flexibility of electronic signatures is increased. At the same time, the seal and certification certificate in the document to be signed after the target electronic signature is processed cannot be extracted or misused, ensuring the security of electronic signatures.

[0074] Example 2

[0075] Figure 4 This is a flow chart of a method for determining a selectable electronic seal provided in the second embodiment of the present invention. Before electronically signing a document to be signed, at least one selectable electronic seal can be first made and determined, so as to determine at least one usable electronic seal based on the selectable electronic seals, thereby realizing the signing process of the document to be signed. The specific implementation method can be found in the technical solution of this embodiment. Among them, the technical terms that are the same as or corresponding to the above embodiments are not repeated here. Figure 4 As shown, the method includes:

[0076] S210: Acquire a pattern file including a preset pattern, and parse the pattern file to obtain the elements required for the seal corresponding to the preset pattern; or, determine the elements required for the seal based on at least one pattern selected in the display interface.

[0077] The pattern file of the preset pattern can be a pre-generated image file containing a seal pattern. The preset image can be a pre-generated seal pattern. The required seal elements can be understood as the elements used to form a selectable electronic seal. For example, the required seal elements include: seal text information, seal shape information, and attribute information such as the size of the seal pattern, double rings, upper and lower chord patterns, and horizontal patterns.

[0078] The display interface may be an interface for displaying a seal pattern. The display interface may include at least one pattern. The pattern may be understood as the elements required to create a selectable electronic seal. For example, the pattern may be a rectangular pattern, a triangular pattern, or a double-ring pattern.

[0079] Specifically, a pattern file containing a preset pattern is obtained and parsed to obtain at least one seal element corresponding to the preset image. Alternatively, in response to a user triggering a selection on a display interface, at least one pattern is determined to be triggered for selection. Attributes are configured for the at least one pattern to determine attribute information corresponding to each pattern. The attribute information is then verified to obtain a verification result. If the verification result indicates a passing verification, the seal element is determined based on the at least one pattern and the attribute information corresponding to each pattern. The attribute information may include, for example, pattern size information.

[0080] For example, in conjunction with the above examples, see Figure 5 . The elements required for the seal can be determined through the parameter configuration unit. The parameter configuration unit includes a template selection operator, a graphic conversion operator, an attribute filling operator and a file parsing operator. When determining the elements required for the seal through the parameter configuration unit, the basic stamp graphic pre-set in the display interface, that is, at least one of the patterns mentioned above, can be selected through the template selection operator in the parameter configuration unit. And the various attribute information in the basic stamp graphic is configured through the attribute filling operator. The attribute information is verified to obtain a verification result. If the verification result is that the verification passes, the elements required for the seal are determined based on the basic stamp graphic and the various attribute information. Correspondingly, if the verification result is that the verification fails, the attribute information is modified until the verification passes. For example, if the current basic stamp graphic is a triangle, the side length of the triangle is the attribute information. Verifying the attribute information can be to verify whether the sum of the lengths of any two sides of the triangle is greater than the length of the third side. If the sum of the lengths of any two sides of the triangle is greater than the length of the third side, the verification passes. Correspondingly, if the sum of the lengths of any two sides of the triangle is less than the length of the third side, the check fails and the length of the triangle is adjusted.

[0081] When determining the elements required for the seal through the parameter configuration unit, the file parsing operator of the parameter configuration unit can also be used to parse and process the offline imaged impression file (a pattern file containing a preset pattern) uploaded by the user to obtain the elements required for each seal, such as the impression shape, x-axis value, y-axis value, whether double ring display is displayed, etc. contained in the offline imaged impression file.

[0082] When determining the elements required for the seal through the parameter configuration unit, the file parsing operator of the parameter configuration unit can also be used to parse and process the offline image stamp file (pattern file containing preset patterns) uploaded by the user to extract the graphic style, color, text and other elements required for the seal from the image of the offline image stamp file.

[0083] After the offline image stamp file or the offline picture stamp file is parsed, the required elements of the stamp are filled into the attribute filling operator to achieve the initial configuration of the required elements of the stamp.

[0084] S220 , displaying a pattern corresponding to the elements required for the seal in a user graphical interface; and obtaining the adjusted elements required for the seal in response to an adjustment operation on the pattern.

[0085] The graphical user interface may be an interface for displaying patterns corresponding to elements required for a seal and for adjusting elements required for a seal. The adjusted elements required for a seal may be elements required for a seal obtained by modifying, deleting, or adding elements required for a seal.

[0086] Specifically, the pattern corresponding to the element required for the seal is displayed on the user graphical interface. In response to the user adjusting the pattern of the element required for the seal on the user graphical interface, the adjusted seal image is determined.

[0087] For example, the user can adjust the pattern corresponding to the required seal elements displayed in the user graphical interface according to actual needs, and determine the adjusted required seal elements based on the adjusted pattern. For example, the shape of the pattern can be adjusted from a triangle to a rectangle to obtain the adjusted required seal elements.

[0088] It should be noted that after the adjusted pattern is determined, the attribute information corresponding to the adjusted pattern may be verified, and if the verification result is that the verification passes, the elements required for the adjusted seal are determined.

[0089] In addition, the elements required for the seal may not be adjusted, and a selectable electronic seal may be generated directly based on the elements required for the seal obtained in step S210 .

[0090] S230. For at least one selectable electronic seal, in response to a triggering operation on at least one seal required element, determine a plurality of target elements constituting the selectable electronic seal, wherein the target elements are elements in the at least one seal required element.

[0091] The trigger operation may be used to trigger the selection of a seal element for generating a selectable electronic seal. The target element may be triggered to be selected from at least one seal element for generating a seal element for generating a selectable electronic seal.

[0092] Specifically, for at least one selectable electronic seal to be produced, in response to a triggering operation on at least one seal required element, multiple target elements constituting the current selectable electronic seal are determined from the at least one seal required elements to generate the selectable electronic seal based on the target elements.

[0093] For example, in conjunction with the above examples, see Figure 6 After the initialization configuration of the elements required for the seal is realized through the parameter configuration unit, a selectable electronic seal can be generated through the stamp drawing unit. The stamp drawing unit includes: a graphics rendering operator, a graphics conversion operator and an element selection operator. Through the user's trigger operation on at least one element required for the seal, it is determined based on the element selection operator whether to load at least one element required for the seal, such as double rings, upper chord patterns, lower chord patterns, horizontal patterns, and intermediate graphics. The target element selected by the user is rendered into the graphics rendering operator of the stamp drawing unit through the element selection operator, and the target element is processed based on the graphics rendering operator to obtain a selectable electronic seal. Optionally, if a trigger operation for adjusting the elements required for the seal is detected, the elements required for the seal to be adjusted can be determined through the element selection operator, and the elements required for the seal to be adjusted can be converted into the adjusted target elements through the graphics conversion operator, and the adjusted target elements can be rendered into the graphics rendering operator of the stamp drawing unit, and the target elements can be processed based on the graphics rendering operator to obtain a selectable electronic seal. For example, if a trigger operation is detected in which the user needs to switch the shape of the seal, such as adjusting the seal shape from a circle to a rectangle, the shape to be drawn can be determined based on the element selection operator, and the text, border and other seal elements originally in the circular mold can be adaptively converted into seal elements suitable for the rectangular mold through the graphic conversion operator.

[0094] S240: Generate a selectable electronic seal based on the typesetting operation of the multiple target elements.

[0095] The layout operation may be a trigger operation for adjusting the position of a target element.

[0096] Specifically, in response to a user's layout operation on a plurality of target elements, position information of each target element is determined, and a selectable electronic seal is generated based on the position information of each target element.

[0097] Optionally, to simplify the subsequent steps of generating the selectable electronic seal and increase the speed of generating the selectable electronic seal, after generating the selectable electronic seal, the method further includes: generating a seal usage instance based on multiple target elements corresponding to the selectable electronic seal, and storing the seal usage instance; wherein the seal usage instance includes text information, shape information, and attribute information of the selectable electronic seal.

[0098] The seal usage instance may include text information, shape information, and attribute information of multiple target elements. Optionally, the pattern file corresponding to the seal usage instance supports offline or online editing.

[0099] The text information of the selectable electronic seal can be understood as the text contained in the selectable electronic seal. For example, the text information can be the XX department's test-specific seal. The shape information can be understood as the shape of the selectable electronic seal. For example, the shape information can be a circle. The attribute information can be understood as various attribute information of the selectable electronic seal. For example, the attribute information can include the line width, radius / diameter length, etc. of the selectable electronic seal.

[0100] Specifically, the text information, shape information, and attribute information of the selectable electronic seal are determined based on multiple target elements corresponding to the selectable electronic seal. A seal usage instance is generated based on the text information, shape information, and attribute information, and the seal usage instance is stored to facilitate subsequent adjustments based directly on the pattern file corresponding to the seal usage instance to obtain the selectable electronic seal required by the user.

[0101] For example, in combination with the above example, after detecting that an electronic seal can be generated, the seal drawing unit can call the seal generation unit so that the seal generation unit generates a graphical or pictorial seal file according to the user's trigger operation selection. The graphical seal file contains key-value pairs of each target element of the electronic seal. For example,

[0102] Stamp text=xxxxx department test special stamp

[0103] Stamp shape = circle

[0104] radiusX=50

[0105] radiusY=50

[0106] line width=2

[0107] After the graphical or image stamp file is generated, the graphical stamp file can be exported to obtain a .ini format file or the image stamp file can be exported to obtain a .png format file. The formatting code corresponding to the graphical or image stamp file, i.e., the aforementioned stamp usage instance, is saved in the stamp storage for persistent management.

[0108] Optionally, the method also includes: configuring a user authority level and a business applicability scope authority for an optional electronic seal, so that when receiving an electronic signature use request, it is determined whether the electronic signature use request is an available electronic seal based on the user information and business applicability type information in the electronic signature use request, and the user authority level and business applicability scope authority configured for the optional electronic seal.

[0109] Specifically, a corresponding user authority level and business applicability scope authority are configured for each prepared optional electronic seal, so that when a request for use of an electronic signature is subsequently received, the user information and business applicability type information carried in the request for use of the electronic signature, as well as the user authority level and business applicability scope authority corresponding to the optional electronic seal, can be used to determine whether the current optional electronic seal can be determined as an available electronic seal, that is, to determine whether there is an available optional electronic seal for the electronic signature request, so that the electronic seal can be used.

[0110] The technical solution of this embodiment obtains the required elements of the seal corresponding to the preset pattern by acquiring a pattern file including a preset pattern and parsing the pattern file; or, based on at least one pattern selected in the display interface, determines the required elements of the seal. The pattern corresponding to the required elements of the seal is displayed in the user graphical interface; and in response to the adjustment operation of the pattern, the adjusted required elements of the seal are obtained, which facilitates the subsequent determination of the target elements based on the required elements of the seal or the adjusted required elements of the seal. In response to the triggering operation of at least one required element of the seal, multiple target elements constituting a selectable electronic seal are determined, so as to generate a selectable electronic seal based on the typesetting operation of the multiple target elements. The embodiment of the present invention can meet the use requirements of electronic seals in different application scenarios by performing the generation process of selectable electronic seals according to the personalized needs of users, and facilitates the subsequent generation process of the target electronic signature by using the prepared selectable electronic seal when receiving the use request of the electronic signature, thereby improving the generation efficiency of the electronic signature.
