Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

Figure 1 is an exemplary diagram showing a font service system according to an embodiment of the present invention.

Referring to FIG. 1, the font service system 1000 may be comprised of a font server 10, a web server 20, and a client 30.

The font server 10 creates and stores several font files and font subsets, and can provide various font information to those requesting fonts.

Specifically, the font server 10 can provide web font information according to a web font request from the client 30, and can perform web font service authentication procedures, web font service registration procedures, etc. Additionally, the font server 10 can create a customer-specific web font module based on web fonts.

The web server 20 is a server for providing web services to users, and can provide website information to clients 30 requesting access to the website.

The client 30 may be a concept that includes a web browser that accesses a website and requests web font information required for the website, or a web view that renders HTML (HyperText Markup Language). there is. For example, the client 30 is a web browser used in smartphones, computers, laptops, and tablets such as Safari, Chrome, Edge, Internet Explorer, and Firefox. It may be, etc. Alternatively, it may include an application that operates in conjunction with a network on an operating system such as Android or iOS.

Hereinafter, the process of registering service usage information for using the web font service will be described with reference to FIG. 2.

Figure 2 is a conceptual diagram showing a service usage information registration process for using a web font service according to an embodiment of the present invention.

Referring to FIG. 2, customers 22 transmit web font service usage information to the font server 10 in order to use the web font service, and the font server 10 selects the customer based on the web font service usage information. You can register. Here, the customer 22 is a user who wants to apply a web font to the web server 20 and may mean a font purchaser.

In addition, the font server 10 checks the font list in the font server 10 to see if a web font to be used by the customer 22 exists based on the service usage information, and if the font does not exist, the source web font corresponding to the font is The source web font can be provided by requesting the font from the source font server 12.

Additionally, the font server 10 may create and store a web font module dedicated to the customer 22 based on the web font, and create and store user authentication information for user authentication.

Then, the font server 10 creates an HTML tag for executing the web font module and provides it to the customer 22, and the customer 22 applies the HTML tag to the website on his or her web server 20. You can use the web font service.

Meanwhile, in FIG. 2, the font server 10 and the source font server 12 are described as separate configurations, but the configuration of the font server 10 and the source font server 12 is not limited thereto. For example, the source font server 12 may exist as one database of the font server 10.

Next, the above-described service usage information registration process will be described in more detail with reference to FIG. 3.

Figure 3 is a timing diagram showing the service usage information registration process according to an embodiment of the present invention.

In Figure 3, in order to increase convenience of explanation, the process of transmitting and receiving information between the font servers 10, focusing on the web server 20 operated by the customer 22, is explained.

Referring to FIG. 3, the web server 20 may purchase a web font to be used on a website from the font server 10 (S101). For example, the web server 20 can purchase each web font individually at a predetermined price, or purchase a license that can be used for a predetermined period of time at a predetermined price. Alternatively, it is also possible to purchase a subscription type that allows you to freely use a specific set of web fonts.

The method of purchasing web fonts is not limited to the above-mentioned example, and can be purchased and used in various ways depending on the sales method of the font server 10.

Next, the web server 20 may provide information for using the web font service to the font server 10 (S102). Specifically, the web server 20 may provide service usage information for using the web font service to the font server 10. Here, the service use information may include at least one of the list of fonts to be used in the web server 20, customer name, product name of the font to be purchased, service use period, application domain, and test IP.

Furthermore, in this embodiment, the range of languages or formats supported by the web server 20 may be different due to the nature of the font, so it is also possible to request service with a replacement font of another similar type for characters in a language or format that is not supported in the text. possible.

Accordingly, the web server 20 may provide service usage information that additionally includes alternative font information to the font server 10. Specifically, a replacement font is a font used to replace characters not included in a specific font with another font and display them on the screen. It may be used when intentionally replacing some characters with another font, and the replacement font information includes the replacement font. At least one of the font's start position, end position, and type of replacement font may be included.

For example, if the Korean font does not contain Chinese character glyphs and needs to be replaced with another font, or if English letters are intentionally displayed by replacing them with a unique font to make them stand out, numbers (U+0030 to U+0039 area) ) when replacing with a specific font, when replacing English capital letters (U+0041 ~ U+005A area) with a specific font, when replacing Chinese characters (U+4E00 ~ U+9FFF area) with a specific font, ASCII code When replacing (U+0200 to U+007E area) with a specific font, replacement font information can be used. At this time, because the area designation within the alternative font information uses Unicode, it can be freely specified for all Unicode text.

Specifically, the replacement font information is {replacement target font ID:[{“range”:[start position, end position], “fontID”: replacement font ID}, {“range”:...}...]} , replacement target font ID: ID of the target font to be replaced, Unicode range: Unicode range of the character to be replaced, [start Unicode, end Unicode] form, number [0030, 0039], English capital letter [0041, 005A], English lowercase letters [0061, 007A] Replacement font ID (fontID): This may be in the form of the ID of the font to be replaced. For example, the replacement font information may have the form shown in FIG. 4.

Furthermore, in this embodiment, it is also possible to extract a replacement font based on the similarity of the vector by using the feature vector of the font list requested as a condition for selecting a replacement font. Additionally, alternative fonts can be set separately by Unicode range.

Specifically, by encoding the features of the font in a specific Unicode, vectorizing it and selecting a replacement font based on the similarity in the feature space where the vectors exist, the sense of heterogeneity due to non-support of the font can be minimized.

The font server 10, which has received the above service use information, can generate a customer unique number as identification information, store it along with the service use information, and obtain and store web fonts based on the service use information (S103). Specifically, the font server 10 may obtain a web font by searching the font list previously stored in the font server 10 based on the font list to be used by the web server 20 in the service usage information.

If there is no font list to be used by the web server 20 in the pre-stored font list, the font server 10 requests the source font from the source font server 12, receives the encrypted source font, and sends the source font to the source font. Fonts are decoded and stored, and web fonts can be obtained and stored using the corresponding source font.

Additionally, the font server 10 may create and store a web font module dedicated to the web server 20 based on the acquired web font (S104). Here, the web font module may be a JavaScript (JS)-based program designed to collect text in a website's web pages for each font, generate CSS information, and add it to the website information.

Additionally, when service usage information includes alternative font information, the font server 10 may create and store a web font module to which the alternative font information is applied.

Additionally, the font server 10 may generate and store user authentication information for user authentication based on the received service usage information (S105). Specifically, the font server 10 may generate and store user authentication information based on information that can identify users in service usage information. For example, user authentication information may include a customer identification number, customer name, applicable domain, and test IP.

Next, the font server 10 may generate an HTML tag for executing the generated web font module (S106) and provide the generated HTML tag to the web server 20 (S107).

For example, the font server 10 may generate HTML tags for executing a web font module as shown in FIG. 5 and provide the HTML tags to the web server 20.

Then, the web server 20, which has received the HTML tag from the font server 10, can use the web font service by applying the received HTML tag to its website information (S108). Specifically, the web server 20 can use the web font service by inserting HTML tags into HTML documents within website information.

According to the present invention, by inserting a short HTML tag into an HTML document, customers can easily apply the font they want to their website. In other words, according to the present invention, convenience of use for users who use paid fonts can be improved.

Additionally, the present invention uses a web font module to which alternative font information is applied, allowing customers to freely mix and use multiple fonts without changing the HTML code of the website.

Additionally, by using a web font module to which alternative font information is applied, the present invention can overcome limitations in the use of existing web fonts, which were limited in use due to glyphs not provided by a specific font.

Meanwhile, when changing the font list to be used, the web server 20 may request the font server 10 to change the font list and receive and use a web font module to which the changed font list is applied.

In this way, customers using the font service can easily change the font applied to the website by applying the web font module to which the changed font list is applied to the website.

Next, with reference to FIG. 6, how the font service system provides a web font service to a client will be described.

Figure 6 is a conceptual diagram showing a web font service method according to an embodiment of the present invention.

Referring to FIG. 6, when the client 30 requests access to a website from the web server 20, the web server 20 can provide website information corresponding to the website to the client 30. there is.

Then, the client 30 requests a web font from the font server 10 based on the website information, receives the web font, and renders it based on the provided web font to display text in the web page of the website. You can.

The web font service method will be described in more detail with reference to FIG. 7.

Figure 7 is a timing diagram showing a web font service method according to an embodiment of the present invention.

Referring to FIG. 7, the client 30 may request web site access to the web server 20 (S201). Specifically, the client 30 may request website access to the web server 20 through the URL of the website.

Next, the web server 20, which has received a request to access the website, may provide website information of the website including HTML tags for executing the web font module to the client 30 (S202). Here, website information is data needed to render the website, and may mean an HTML document containing contents such as images and text.

And, when the client 30 renders a web page, the web font module is executed through an HTML tag in the website information, and the executed web font module collects the texts in the web page of the website for each font and creates text for each font. Information can be generated (S203). Here, text information for each font may mean data that organizes the minimum text required to render a website for each font.

Specifically, the step of generating text information (S203) is to collect the texts in the web pages of the website by font, remove duplicate texts from the collected texts, and de-identify them by sorting the texts in Unicode order ( de-Identification) can be performed.

In addition, in the step of generating text information (S203), if the length of the text among the texts collected for each font in the web page of the website exceeds a predetermined length, the text is divided into a predetermined length and the text for each font is divided. Information can be generated. In other words, by dividing text sorted in code order into unit lengths, responsiveness can be increased and additional de-identification effects can be achieved. Additionally, the unit length for dividing text may be variably determined depending on the font type of the text, the total number of fonts to be used, and the currently available resources of the font server 10. For example, if the currently available resources are small, the predetermined length may be determined to be short.

Additionally, the step of generating text information (S203) may determine whether a replacement font is needed. Specifically, in the step of generating text information (S203), the presence or absence of text corresponding to the replacement font among the texts collected for each font within the web page of the website may be determined based on the replacement font information.

For example, if there is text corresponding to the unicode range of the character to be replaced among the collected texts, the web font module may determine that a replacement font is needed. As described above, in this embodiment, by removing duplicate text and sorting the text in Unicode order, elements with literal meaning included in the text are de-identified, and the application range of the alternative font is adjusted according to the sort order. You can make decisions more efficiently.

Therefore, in the step of generating text information (S203), when text corresponding to a replacement font is included among the collected texts, text information for each font is generated by distinguishing between text corresponding to the replacement font and text not corresponding to the replacement font. can be created.

For example, in the step of generating text information (S203), among the collected texts, the text corresponding to the replacement font is distinguished from the text other than the text, the duplicate text is removed, de-identification is performed, and the length of the text is determined. Text information for each font can be generated by dividing text exceeding a predetermined length into a predetermined length.

Next, the executed web font module can generate CSS (cascading style sheets) information containing the location information of the web font based on the text information for each generated font and add the generated CSS information to the website information (S204 ). Here, CSS information is a style sheet that stores the overall style of a web document, and may include information on text font type, font size, font style, font thickness, etc., as well as text information for each font.

Additionally, the client 30 may transmit web font request information from the font server 10 based on CSS information in the website information (S205). Here, the web font request information may include data about the requested web font and various data required for an authentication procedure to use the web font service. For example, web font request information may include CSS information and user authentication information. Here, the user authentication information may be obtained from the web server 20.

Next, the font server 10 may perform a web font service authentication procedure using the web font request information received from the client 30 and the previously stored user authentication information (S206). Specifically, the font server 10 may determine whether the request has normally passed through the customer company's web server 20 by comparing user authentication information in the web font request information with pre-stored user authentication information.

If it is determined that it is an abnormal access, the font server 10 may transmit an error response to the corresponding client 30 and provide the fact of the abnormal access to the corresponding web server 20. Here, abnormal access is a web font request that does not go through the customer company's web server 20. For example, an ordinary user hijacks the URL requested from a web browser to the font server 10 for the purpose of acquiring a web font file and directly accesses it. This may include a request to the font server 10, etc.

In other words, the present invention can prevent the font design of a paid font from being leaked by rejecting a web font file request from a domain or IP that has not been registered in advance through the above-described authentication process.

Additionally, if it is determined to be a normal font request through the service authentication process, the font server 10 may generate an optimized web font subset based on the web font request information (S207). Here, the web font subset may refer to a font file with a reduced number of characters to improve dynamic loading performance.

Specifically, the font server 10 may generate a web font subset by performing font subsetting based on text information in web font request information and pre-stored web fonts.

In this embodiment, the subset can be dynamically created considering characteristics of each language.

For example, in the case of Hangul, the shape of each glyph may change depending on the combination of consonants and vowels, and therefore it is necessary to include more diverse glyphs in the font compared to English.

In other words, each general character grapheme can be divided into glyphs as a unit, but considering the combination relationship between characters, a set of glyphs can be formed for each specific character and included in the font file.

At this time, in this embodiment, the text in the web font request information is analyzed, but only the necessary glyphs are extracted from a wider range of glyphs considering the combination relationship between consonants and vowels, and the subset is dynamically implemented, thereby reducing the size of the font file, and the browser so that the text can be displayed by processing it efficiently.

Furthermore, at this time, the set of glyphs according to the character combination relationship can be composed by dividing consonants based on the shape of the vowel, with and without a consonant. Vowels can be divided into those with and without consonants.

In the case of other Chinese characters or Japanese, specific characters whose form changes depending on the character combination relationship can be composed of a set of glyphs, and the text in the web font request information is analyzed to configure the corresponding glyphs from the set of glyphs into a subset. Thus, text information for each font can be provided.

That is, in this embodiment, the text information for each font further includes identification information that defines the combination relationship of specific characters in the text, and the font server can generate a subset using Ing.

Additionally, the font server 10 may store the generated web font subset for a predetermined period of time. Here, the predetermined period may be variably determined depending on the size and frequency of use of the web font subset. For example, if the size of the corresponding web font subset is large or frequently used, the font server 10 may increase the given period, and if used infrequently, the font server 10 may shorten the given period.

Next, the font server 10 may transmit web font information to the client 30 based on the web font request information (S208). Here, the web font information is data composed of web font subsets created based on text information in the web font fairy information, and may also include a replacement font subset depending on whether or not a replacement font is included.

If the same web font request is received from the client 30, the font server 10 may directly transmit web font information to the client 30 based on a previously created and stored web font subset.

Then, the client 30 can display text by rendering a web page in the website based on the web font information provided from the font server 10 (S209). For example, text on a web page within a website may be displayed as shown in Figure 8.

Specifically, Figure 8 (a) is an example of a web page screen within a website before a web font is applied, and (b) is an example diagram showing a web page screen within a website after a web font is applied.

In addition, in (b) of Figure 8, the replacement font function is applied so that the text in the title area is displayed by replacing English and numbers with a purple font, and the text in the body area is displayed by replacing English and numbers with a font of a different shape.

According to the present invention described above, by using a web font module that collects text in a website by font to generate text information, generates CSS information based on this and inserts it into an HTML document, web fonts are used when rendering a web page. Time consumption due to use can be minimized.

Additionally, the capacity of web fonts can be reduced by using an optimized web font subset when providing web font information.

Additionally, by reducing the capacity of web fonts, the download time of web fonts can be shortened and network traffic and costs can be reduced.

Additionally, by using a web font module to which a replacement font is applied, the present invention can easily replace missing glyphs of a specific font or mix it with different fonts to make specific letters stand out.

Meanwhile, the above-mentioned web font service is not limited to web fonts provided on websites and can be applied to various fields of displaying text. For example, the above-described web font service can also be applied to interactive applications such as messengers.

Below, the service usage information registration process for using an application-based font service will be described with reference to FIG. 9.

Figure 9 is a conceptual diagram showing a font service usage information registration process according to another embodiment of the present invention.

Referring to FIG. 9, the customer 22 who purchased the font to be applied to the application registers the information necessary for using the font in the font server 10, and the font server 10 sends the source font to the source font server 12. It can be provided upon request.

Then, the font server 10 creates font request form information and provides it to the customer 22, and the customer 22 can use the font service by applying the font request information in the account of the application operation server 40.

This will be described in more detail with reference to FIG. 10.

Figure 10 is a timing diagram showing a service usage information registration process according to another embodiment of the present invention.

Referring to FIG. 10, the application operation server 40 provides service modules such as font purchase, and the customer 22 can purchase fonts through the application operation server 40. Here, the application operation server 40 is a server that services an interactive application, and the customer 22 can request a font service through an interface provided by the application operation server 40.

Therefore, the following will describe the processing process of the application operation server 4 that performs a request according to the customer 22's interface.

First, the customer 22 can purchase a font provided by the font server 10 through the application operation server 40 (S1001). Next, the application operation server 40 may provide service usage information for using the font service to the font server 10 (S1002).

Additionally, the font server 10 may request and receive a source font from the source font server 12 based on the received service usage information, and obtain and store the font based on the source font (S1003).

Additionally, the font server 10 may generate and store user authentication information (S1004).

Additionally, the font server 10 may generate and store font format information for requesting a font based on the acquired font (S1005). Here, the font style information may include information about font type, font size, font style, font thickness, etc.

Next, the font server 10 may provide the generated font format information to the application operation server 40 (S1006).

Additionally, the application operation server 40 may provide a font service by setting a font based on font format information (S1007).

Meanwhile, since steps (S1001) to (S1007) described above are performed in the same manner as the web font service registration process in FIG. 3, detailed descriptions are omitted.

Next, a method of providing an application-based font service will be described with reference to FIG. 11.

Figure 11 is a conceptual diagram showing a method of providing a font service according to another embodiment of the present invention.

Referring to FIG. 11, when the first client 51 using the application selects a font to use for chatting through a chat application and then inputs conversation content, the application operation server 40 provides font format information along with the corresponding conversation content. It can be transmitted to the first client 51 and the second client 52, respectively.

The first client 51 and the second client 52 may request a font from the font server 10 based on font format information, receive font information, and then display text in the application based on the font information. there is. Here, the first client 51 and the second client 52 are terminals of users using the application and may include smartphones, tablets, and PCs.

In relation to this, a method of providing an application-based font service will be described in more detail with reference to FIG. 12.

Figure 12 is a timing diagram showing a method of providing a font service according to another embodiment of the present invention.

Referring to FIG. 12, the first client 51 may select a font to be used through the application, enter conversation content, and transmit it to the application operation server 40 (S2001).
