Description

System and method for providing URL using pattern, and method for accessing information resource using the same {System and Method for providing URL using pattern, and method for acquiring the network resource by using the same}

The present invention relates to a web image in which the IP address and / or URL is encoded in an information indicating a location of a resource on a network, in particular an IP address and / or a uniform resource locator (URL) representing an address of a website in the Internet. The present invention relates to a URL providing service system and a method using a pattern so that a user can easily access an Internet resource.

Recently, due to the rapid development of technology in information and communication, the Internet has become an indispensable element of life in all fields of society. The so-called Internet has become a huge place of information, and for Internet users, it is a necessary resource given the reality of accessing the location of the resource directly or obtaining an address through a search site in order to obtain a desired website or information. A lot of time and effort is wasted accessing.

Every server computer that provides information to the Internet is given a unique number generated by a 32-bit number combination. This unique number is the identification number of the individual server computer, which is the Internet address of each server. The unique number is called an IP address, and is divided into four groups of eight bits and displayed by dividing them into dots. The unique number is represented by any one of numbers 0 to 255 consisting of a combination of eight bits for each group. Since the above IP address is composed of a combination of numbers, it causes a lot of confusion and difficulty in understanding or remembering the Internet address of a specific site. In order to solve this problem, the Internet address of the number combination is converted to the Internet address of the string combination, and the Internet address of the character combination is called a domain name.

However, the domain name is also not familiar to users of non-English speaking countries because it is an array of non-native English alphabets, and thus, it is difficult to memorize a domain name relatively to a citizen of a non-English speaking country.

In addition, the number of identifiable numbers of Internet domains may reach billions in theory, considering the combination of letters. However, due to the nature of the Internet, Internet domain names that are widely known to many people and easily accessible by many people are limited. As a result, latecomers who have fallen behind in the domain name competition are unable to register recognizable domain names related to their businesses, and the available domain names are almost exhausted.

Currently, the domain name registration system takes pre-registration, and if it is not the same as the existing registered domain name, it registers first. This causes trademark disputes by registering unrelated third parties with domain names similar to brand names, trade names, and so on. Companies, etc. promote and advertise companies and products through off-line names such as trade names, trademarks, product names, and online domain names, and invest a lot of money, but online domain names are due to the pre-registered domain owners. It is not easy to register a domain name integrated with offline, and consumers and Internet users are also mistaken for this problem.

In recent years, Internet name domain services have been provided using Internet keywords, making it easier for Internet users to access Internet resources. However, the Internet keyword services are limited in terms of keywords and are not linked to websites that are truly desired. There is a problem.

The inventor of the present application has completed the invention related to a method and system for providing related information of an object including a physically readable identifier and filed a patent as Korea Patent Application No. 2000-0032164 dated June 12, 2000, Completed the invention about the coded pattern and its code extraction method and filed a patent application as Korean Patent Application No. 2000-0085811 dated December 29, 2000. In addition, the invention on the site selection and its automatic connection method has been completed and filed a patent application as Korea Patent Application No. 2001-0038938 dated June 30, 2001.

In connection with the contents of the invention disclosed in the above-mentioned patent application, a problem of a domain name service system and a website access method using the same will be solved in the present specification.

The present invention is to solve the problems of the existing domain name service and to access the resources of the network more conveniently and easily, to provide a URL desired by the client using a pattern.

In addition, a client wants to provide a desired URL through a URL providing service using a keyword or the like.

1 is a block diagram schematically illustrating the structure of an existing domain name service system.

When the user's computer 101 requests the domain name server 103 to check the IP address of the website having a specific address, the domain name server 103 registers the IP address. Contact the server 111 of the server, obtain the corresponding IP address, access the domain name server 105 related to the web address, obtain the address of the desired website with the help of the domain name server 105, and return it. Will receive. When the returned IP address of the website is returned to the user's computer, the client connects to the desired website.

In the above process, when the user 101 inputs a domain into the address box of the web browser, the local Internet service provider (ISP) 103 sends the IP address corresponding to the domain name to the server 111 of the domain name authority registration mechanism. After inquiring, after receiving the corresponding IP address, the process of accessing the domain name server 105 related to the IP address and receiving the address of the corresponding website is performed.

Figure 2 is a schematic diagram schematically showing the shape of the pattern used in the present invention.

In the present invention, an Internet user may use a pattern or a keyword instead of a URL or an IP address to access the website.

The pattern referred to herein refers to an image of a two-dimensional lattice structure composed of small circular symbols, and a keyword refers to a string consisting of numbers, letters, symbols, or a combination thereof except for a dot.

Referring to the pattern shown in Fig. 2, a plurality of small circular symbols forming a pattern are located in a two-dimensional lattice structure. In addition, the code value is characterized in that it is determined according to the size, position, shape, color, etc. of each symbol. The number of codes may be further extended by expanding the lattice structure of the symbol and increasing the number of symbols.

3 is a block diagram showing the structure of a URL providing service system using a pattern according to the present invention.

The client computer 301 is connected to a URL providing service system using a pattern through a network, and the URL providing service system using a pattern includes a registration processing unit 305, a search unit 307, and a pattern generator 309. ), And a database 315.

The system for providing a URL to a client includes, for each URL, a database 315 in which a code number and a keyword are recorded, and a code number or keyword is input from a client, and the URL corresponding to the code number or keyword is referred to by the database 315. It includes a search unit 307 to search for and return to the client. In addition, the terminal receives a predetermined registration information from the client, assigns a code number, receives a code number from the registration processing unit 305 and registration processing unit 305 for registering in the database, and generates a pattern generator 309 for generating a pattern. Include.

Hereinafter, each component will be described in more detail.

The client computer 301 may be a computer device having an information processing function and a communication function, and typically, a PC, a notebook computer, a PDA, a handheld PC, a portable terminal, or the like may be used. The terminal of the client is equipped with a web browser, it is preferable that the image (pattern) recognition means 303 that can recognize the pattern is connected to the client computer (301).

The client system may be a mobile device or a wireless communication device capable of wireless Internet service. System structure and operation in the mobile environment as described above will be described later.

The pattern recognizing means 303 is connected to the client computer 301 and performs a function of recognizing a pattern from an external object in which a physically recognizable pattern is imprinted and transmitting the pattern to a URL providing service system using the pattern. The pattern recognition means 303 may be an optical sensor, a scanner, a PC camera, a digital camera, a web camera, or the like.

The registration processing unit 305 operates in real time interactively with the client, receives predetermined information from a client who wants to use a URL providing service using a pattern, stores the input information in a database, and assigns a registration number. Predetermined information inputted to the registration processing unit 305 is inputted with pattern link information and user information. The pattern link information corresponds to information such as keywords, connection URLs, registration periods, and the like. The information is relevant and stored in database 315. In addition, the pattern code number or the predetermined information for generating a pattern is automatically allocated to the pattern generator 309 when the service pattern is used.

The pattern generator 309 is connected to the registration processing unit 305, receives the pattern code number and predetermined information from the registration processing unit 305, generates a corresponding pattern, and returns the pattern file to the registration processing unit 305. To pass.

The pattern code number is issued by the registration processing unit 305, and may be any number randomized. The registration processing unit 305 extracts and assigns an arbitrary numeric code to the applicant regardless of the applicant's registration order or IP address. The pattern appearing on the system screen of the client is stored on the system in the form of the randomized pattern code number, that is, a predetermined number of digits, and is transmitted between the client and the URL providing service system using the pattern.

According to another embodiment of the present invention, the pattern registration processing unit 305 may issue a registration number to the applicant. In some cases, the pattern code number may be used as a registration number instead of a separate registration number.

According to another embodiment of the present invention, an IP address value of a corresponding URL may be used as a pattern code number, or an ASCII code value of a keyword used additionally may be used as a pattern code number. That is, the pattern code number used in the present invention is generally preferably a randomized random number code, but is not limited thereto. It is also possible to use a number associated with a URL or a corresponding resource as the code number.

The pattern code number transferred from the registration processor 305 is imaged through the encoding process in the pattern generator 309.

The pattern file generated by the pattern generator 309 is retransmitted to the registration processing unit 305, and the registration processing unit 305 stores the image file of the generated pattern on the URL providing system using the e-mail and the pattern of the client. The client can access the service provider's website at any time, download the image file, and use it for printing.

The database 315 stores various kinds of information for the URL providing service using the pattern of the present invention. The information stored in the database 315 may store pattern link information, user information, and other additional information. The pattern link information may be a code number, a keyword, a URL to which the user is connected, the user information may be an institution name, an address, a contact number, and the like, and other additional information may be payment information and tax invoice information. The structural form of the database 315 will be described later with reference to FIG.

The search unit 307 reads the pattern code number or keyword input from the client, and then searches the URL corresponding to the pattern code number or keyword in the database 315. If the URL is searched, the connection URL corresponding to the pattern code number or keyword is returned to the client system program, the client is connected to the desired website, and the URL corresponding to the pattern code number or keyword received from the client is returned. If the search fails, an error message may be sent to the client, or the search result may be provided through an internet search engine using a keyword list or additional information including a keyword input by the client.

According to another embodiment of the present invention, the search unit 307 may additionally perform the role of a domain name server (DNS). That is, when a connection URL corresponding to a pattern code number or keyword is found, a service for directly providing an IP address may be performed using the connection URL without returning to the client.

4 is a flowchart illustrating a process of registering a URL providing service using a pattern used in the present invention.

The user accesses the website of the service provider (401).

It is checked whether or not the user agrees to a predetermined condition for using the pattern link service (403).

If you agree to the terms and conditions, fill out and enter the prescribed application (405).

The application should include the client's basic information and the client's website address, which will be linked to the pattern. The client's website address must contain a URL and, optionally, an IP address. If the client does not own the URL, a reservation registration service is available that first registers the keyword and pattern code number through a prior application and omits the URL input process. In this case, URL input should be made within a predetermined period after the reservation registration.

After the application is completed, select and enter keywords.

The application form and keyword selection process may be performed in a separate step or in one step.

The information source linked to the connection URL may use keywords in addition to the pattern.

Since duplicate keywords cannot be used in the provision of this service, the registration processing unit 305 searches the database 315 and inquires whether a keyword desired by the client is available (407).

First, it is preferable that the registered keyword or the prohibited keyword is not registered, and if the keyword cannot be registered as a search result, it is reselected.

If the registration information is input, it is registered in the database 315 of the URL providing service system using the pattern (409).

In the database registration procedure, basic information registration and additional information are registered and may be operated as a system management and modification procedure.

The registration processing unit 307 assigns its own registration number. The self-registration number may be used only in the system or in some cases, an additional service additionally operated in the service system. The registration number is stored along with other information in the form of a table in the database. The registered registration number and URL are stored in a table form corresponding to the pattern code number, additionally input keywords, and the like in the database 315.

Information related to the user's website or other resource is linked with the pattern code number, and the pattern code number generates a pattern of the type shown in FIG. 2 through the pattern generator 309 (411).

The client may reconfirm the registered result through the final screen, or may check the registered result through e-mail or registration result information of the website, and may modify or cancel the registered information (413).

The registration service system sends a registration result to the client's e-mail when the registration process is completed (423).

Hereinafter, the pattern generation process will be described in more detail with reference to FIG. 5.

5 is a flowchart sequentially illustrating a process of generating a pattern.

When a user applies for a URL providing service using a pattern, a pattern is generated after performing a registration step of registering in the database.

According to another embodiment of the present invention, after the pattern is generated, the registration procedure may be performed in the database.

The registration processing unit 305 inquires the code values available from the database 315 (501).

After inquiring from the database 315, usable code values are extracted (503).

The extracted usable code value is returned to the registration processing unit 305 (505).

According to another embodiment of the present invention, the code value may include size and color information of an image, in which case the registration processor 305 transmits the code value to the pattern generator 305.

In an embodiment in which the code value does not include the size and color information of the image, the registration processor 305 transmits additional information for generating a pattern such as the size and color of the image together with the code value (507).

The pattern generator 309 generates a pattern corresponding to a code value by using a pattern generator (509).

The generated pattern image file is retransmitted to the registration processor 305 (511). When the generated pattern file is retransmitted to the registration processing unit, the registration processing unit 305 delivers the generated pattern file to a means capable of transmitting image files such as a client's e-mail or a service provider's database, and the image file received by the client at any time. Print it out for various uses.

Fig. 6 shows the user's environment for the pattern link service and the initial screen of the client program.

The user can use any device that can access the network, such as a PC, a notebook, a handheld PC, or a mobile terminal equipped with a web browser. The user's network connection device environment includes a web camera, a digital camera, and an optical sensor that can recognize a pattern. It is preferable that a scanner or the like is installed and connected.

According to another embodiment of the present invention, even if there is no pattern recognition means, the user may download his or her own pattern from a server and record the pattern on a storage device such as a computer.

The user's system 605 shown in FIG. 6 shows a PC as an example. In the present invention, not only the PC but all the above-mentioned network connectable devices can be used as the user's system.

Further, even a wireless mobile communication device capable of wireless internet can be used as the user's system 605 if network connection is possible.

The client downloads a program provided by the service provider in order to receive the pattern link service.

The program can be executed independently, recognizes and decodes the pattern, passes the pattern code number to the URL providing service system using the pattern, performs image recognition and URL request functions that return the URL, and receives the URL and then returns the client. It performs a plug-in function that enters a URL into the system's web browser address bar. The plug-in program refers to software for displaying various types of files that cannot be displayed by a web browser in a window of the web browser. Because it works with a web browser, it works as if the web browser itself has a file display function without having to open a separate application window. From the user's point of view, it seems that the web browser itself is extended, and when installed on a storage device such as a user's hard disk, the web browser is automatically set.

The pattern recognition function, the URL request function, and the plug-in function may be processed in one program, and in some cases, may be performed with an independent program that performs each function.

Hereinafter, a program that performs the above function is collectively called a client program.

The client program may be provided to the client through a corresponding service provider or other Internet search page. After installing the downloaded client program on the client system, the client program is set to operate on one side of the web browser through simple setting.

The client program is connected to a web camera or image recognition means 603 installed on the client computer, and is provided as an image recognition software. In addition, a keyword input window is installed at the bottom of the main screen of the client program. Web pages can be accessed through keywords. The image recognized by the image recognition means 603 is transmitted to the client program 607, and the pattern is converted into a numeric code by decoding the code value corresponding to the pattern in the client program 607. In addition, the client program 607 performs a function of inputting the connection URL returned from the URL providing service system using the pattern into the address box of the web browser, thereby performing a function of accessing the URL.

Referring to the screen of the client program 607 of Fig. 6, a circular pointer 615 is displayed at the center of the screen, and the pointer 615 is brought into contact with the pattern recognition means 603 by the information source 601 on which the pattern is printed. The pattern is recognized so that the pattern contacts the part.

At the bottom of the client program 607, a keyword field is separately installed, and when a keyword or pattern is recognized, the target website can be accessed as in the address bar of the web browser, which can be accessed in detail. Explain.

7 is a flowchart illustrating a method for a client to access a network resource using a pattern.

The website access method using the pattern or keyword may be performed individually or simultaneously.

First, the method of accessing the website through the pattern will be described.

The client selects a pattern through a preinstalled client program 605 and pattern recognition means to recognize the pattern in the user's system (701).

According to another exemplary embodiment of the present invention, a pattern stored in a file format may be recognized in a storage device of a user system.

For example, the pattern may be any type as long as it is imprinted on a physically contactable medium printed on a business card, various cards, or various printed matters. The pattern is printed so as to be obtained at an appropriate resolution by a pattern recognition means, and simply contacts. It is preferable to be a form which can be recognized by doing so.

In the pattern recognition process, an image acquisition process is provided as an image on a computer screen of a client, and when an image comes into contact with a predetermined circular pointer 615 located in the center of a window in which the program image appears, a still image for the image is obtained. .

The client program 605 converts the recognized pattern into a code value corresponding to the pattern (703).

The converted code value is transmitted to the URL providing service system using the pattern by the client program (705).

The search unit 307 of the URL providing service system using the pattern inquires the connection URL mapped to the corresponding code value from the database 315 (707).

As a result of the search, if the connection URL search is successful, the search unit 307 returns the URL linked to the pattern to the client program or the web browser (711).

According to another embodiment of the present invention, the service may be provided to directly access the URL.

After driving the web browser, the client program inputs the URL returned from the search unit 307 into the address box of the web browser, and accesses to the corresponding URL (713).

On the other hand, if the search fails, an error message is transmitted (725).

According to another embodiment of the present invention, if the search fails, the relevant site is searched through an internet search engine or the like using a keyword list or additional information including a keyword input by the client (717). The additional information may be a business type, business name, telephone number, and the like.

When a search result related to the resource is searched based on the additional information, the search result is provided to the client (721).

If the search using the additional information fails, an error message is transmitted to the client (725).

8 is a flowchart illustrating a method in which a client accesses a network resource using a keyword.

In addition, the method of accessing the website by the input keyword will be described.

The keyword is entered in the address bar of the client program or the web browser (801).

When a keyword is input in the keyword input box of the client program or the address box of the web browser, it is determined whether the input content in the client program is a URL or an IP address or a keyword (803).

The determination may be made by searching whether a dot exists in the input string. If there is a dot in the string, it is determined as a URL or IP address and connected to the website in the same process as the existing domain name service system.If a dot does not exist in the string, it is recognized as a keyword. The character string is transmitted to the URL providing service system using the pattern (805).

The transmitted keyword performs a search in the database of the database management system to search for the existence of the linked URL (807).

If the search for the URL linked to the keyword is successful, the URL is returned to the client computer (811).

The web browser of the client computer receives the URL transmitted from the URL providing service system using the pattern, extracts the domain name part, and transmits it to the domain name server. The domain name server receives the domain name and transmits the IP address corresponding to the domain name to the web browser by referring to the database.

The client accesses the target website with the IP address retransmitted through the above process (813).

In case of failing to search for a connection URL mapped to a keyword The following process is the same as the case of failing to search for a connection URL using the pattern of FIG. Omitted below.

The website access process using keywords is similar to the website access method using the pattern described in FIG. 7, but is a service using characters, not images, and thus is more easily accessed without converting the pattern of FIG. 7 into a code value. Will be the way.

The pattern link service and the keyword providing service may be operated independently or additionally. The database combines both the pattern link data and the keyword link data, and eventually there are two pattern link data and keyword link data in one URL.

The structure of the database of the pattern link service system will be described in more detail with reference to the following drawings.

9 is a schematic diagram schematically showing the structure of a database of a pattern link service system.

The database 315 includes a unique registration number 901 assigned by the registration processing unit 305, a URL 903 of a website or a network resource, an IP address 905, a keyword 907, a code number 909 of a pattern, The mobile code number 911 and the additional information 913 and 921 are stored in a table form.

The unique registration number 901 is a unique number provided by the service provider by itself and assigned to the subscriber, which is a registration number provided for structural processing and classification of data on the service. The registration number 901 may use a pattern code number 909 for pattern generation, or may be used by giving a concept independent of the pattern code number 909.

URL 903 refers to a standardized logical address for representing various resources such as files and newsgroups on the Internet. It consists of the protocol to use, the name and address of the main computer, the location of the directory where the file is located, and the file name. When a keyword or pattern is sent to request a linked URL, the stored present URL on the database is provided to the client.

IP address 905 is an address for identifying a transmission source and a transmission line when communicating with TCP / IP. In general, every 8 bits (1 byte) are separated by periods and represented by four decimal numbers. Substantially, the URL 903 is provided to the client, and the client's web browser is provided with the URL 903 to access the website by requesting an IP address again. However, in some cases, the IP address may be stored together with the URL in the database to provide the client with the IP address 905 to access the website more quickly and directly. This can be provided by entering the IP address with the URL when the initial subscription application is made.

A plurality of keywords 907 may be mapped and stored in the corresponding URL, and may be numbers or letters. It is meaningful to be used as a simplified address instead of the URL selected by the user at the time of initial sign-up, and the keyword character may be used as a keyword if the character string does not include a dot in a string other than an alphabetic character.

The pattern code number 909 consists of an arbitrary number having a predetermined number of digits, and is issued by the registration system 307. If the pattern code number 909 is not duplicated, the pattern code number 909 is issued and stored as an arbitrary random number instead of being issued sequentially. However, in some cases, an individual's unique number may be used as the pattern code number. For example, the service registration number, social security number, or payment number used for electronic payment in connection with the user may be used as the pattern code number.

The mobile code number 911 is a code number that uses '#' and '*' which are symbols commonly used in telephones and numbers, which are used instead of keywords or patterns. In the mobile terminal, keyboard input is limited to numbers, symbols, and the like, so that if a code number consisting of a combination of numbers and symbols is stored in the database 315, it may be a more convenient way to use the service when using the wireless Internet on mobile. Can be. The mobile code number 911 has a predetermined number of digits consisting of a number and a symbol on a keypad of a mobile phone, and may be operated by being linked with a URL.

The additional information 913 is information that can identify a URL other than the pattern or keyword, and can be a classification code or an identifier that can be used when searching in a search engine.

According to still another embodiment of the present invention, keywords and patterns may be separately classified and operated in two different databases. Or, it consists of two tables, and only one keyword is mapped to one table and only patterns are mapped to another table.

10 is a schematic diagram schematically showing the structure of a URL providing service system using a pattern on a mobile.

The service represents an embodiment of accessing an Internet website using a mobile device.

The user's mobile device 1001 can be connected to a network, requires an environment in which a client program distributed by the service provider is installed, and is preferably provided with image recognition means such as a web camera or a digital camera. .

When a pattern or keyword, and also a mobile code number, is input at the user's portable terminal, a client program or a web browser on the user's portable terminal transmits it to the base station 1003. The base station 1003 transmits the transmitted information to the gateway 1005, and the gateway 1005 performs conversion between the WAP protocol and the WWW protocol. After the conversion is performed through the gateway 1005, a URL providing service using a pattern may be provided using the internet wired network in the same manner as described above.

An embodiment of an additional service provided by the pattern link service system according to the present invention will be described.

Web content service using pattern

By mapping the URL to be connected to the content that provides a video or other multimedia environment to the symbol imprinted on the information source, it is possible to provide a variety of content providing services other than a simple website access service.

According to one embodiment of the present invention, a symbol is printed on a movie pamphlet or a poster, and the symbol is mapped to corresponding movie content information to provide a client with a movie advertisement, movie-related information, and a booking function.

According to another embodiment of the present invention, when a symbol is imprinted on a business card, the client may provide the card owner with access to the homepage, send an e-mail, and personal information of the business card registrant using the symbol.

The web content service using a pattern may be provided as various services capable of supporting multimedia, and is not limited to the above examples.

Electronic payment service using patterns

Recently, online e-commerce is active and electronic payment systems are widely used, but complicated authentication systems and authentication number input processes are becoming obstacles to the service. In addition, the security problem of not leaking numbers in the electronic payment service is also an important problem to be solved.

Electronic payment and personal authentication service using the pattern of the present invention has a number of advantages because the number can be easily released by giving an authentication number or a personal code number on the pattern.

If you print and use patterns on your resident registration card, license, medical insurance card, or credit card, you can provide electronic payment services more easily, easily and safely.

As described above, according to the present invention, the client can easily access the resource by simply accessing an internet website or network resource to be acquired on the network by simply inputting a pattern, and inputting a string. Even if a terminal of a user without a device is provided with a pattern recognition means, the user can easily access a website from anywhere. In addition, users do not have to remember each website or resource address individually and store them separately. By imprinting a pattern on a credit card or ID card, users can securely and conveniently use a personal authentication or electronic payment system to prevent the leakage of complicated numbers or personal credit information. There is a usable effect.
