How to search mail {Method for Searching Mail}

The present invention provides a mail retrieval method executed by a server, wherein a temporarily stored mail is checked before being delivered to the mail receiving side, and a file including a specific keyword or matching the specific keyword is included in the body of the checked mail. And a mail retrieval method for retrieving the attached mail, processing the displayed mail to display at least one advertisement content, and processing the processed mail to be delivered to the mail receiving side.

A mail (= e-mail) is a message transmitted through a computer communication network, or a message transmitted, which is created by a predetermined mail user agent (MUA) provided in a mail sending client terminal and at least one or more through a communication network. Received through an MTA and / or MDA to a mail server used by a mail receiving client and stored in an electronically implemented mailbox for the mail receiving client on the mail server, and through a predetermined MUA provided in the mail receiving client terminal. The mail is to be accessed at any time. Such a mail system is defined in a message handling system (MHS) of the International Telecommunication Union-Telecommunication standardization sector (ITU-T) Recommendation 400 series.

1 is a diagram briefly showing the functional configuration of a conventional mail system using a single mail server.

In particular, FIG. 1 illustrates a mail server and a mail system for receiving a predetermined mail through a single mail server according to the ITU-T Recommendation 400 series of standard message communication processing systems (MHS).

Referring to FIG. 1, a process of receiving a predetermined mail and checking the received mail by the mail receiving client will be described below.

The MTA provided in the mail server receives a predetermined mail from at least one or more other MTAs and / or MUAs through the Simple Mail Transfer Protocol (SMTP) communication protocol, and sends the received mail to another MTA by calling an MDA, or It is a program to deliver the mail to the mailbox of the receiving client.

When a predetermined mail is received, the MTA sends a local call to a local MDA through a system call if the mail receiving client address included in the header of the received mail is a mail receiving client in charge of the mail. Instructing the received mail to be stored in the mailbox of the mail receiving client, and conversely, if the mail receiving client address included in the header of the received mail is not the mail receiving client in charge of the mail, the mail is forwarded to another MTA. )do.

The MDA provided in the mail server is a program used by the MTA to deliver a received mail to a mail receiving client, and is divided into a case of delivering the received mail to the outside and a case of delivering the received mail to the inside.

When the MDA delivers the received mail to the outside, each MDA exists according to a channel (for example, TCP or UUCP), and is driven by “/ bin / sh” in UNIX. When the received mail is delivered internally, an MDA for storing the received mail in a mail receiving client's mailbox is called a local MDA. For example, a program such as “procmail” or “/ bin / mail” is used in UNIX. have.

Local MDA generally stores the incoming mail in the mailbox of a mail-receiving client on the local file system, optionally using a mail filter (e.g., a program that filters spam) that processes the mail. .

A mailbox is a storage medium that contains a predetermined format for storing mail. Since there is no unified standard format, you can define and use your own format. The method and the method of storing each mail in each directory as a separate file are used, and in most cases, a method of continuously appending to a single file is often used.

When a predetermined mail is received in the mailbox as described above, a mail receiving client corresponding to the recipient of the received mail should access the mailbox remotely through a remote MUA provided in the corresponding mail receiving client terminal. It includes at least one Mail Retrieval Agent (MRA) that includes a Post Office Protocol (POP) daemon and / or an Interactive Mail Access Protocol (IMAP) daemon.

The MRA is a program for the mail receiving client to remotely access the mailbox through a remote MUA. When a remote MUA provided in a mail receiving client terminal requests an incoming mail to the MRA, the MRA is provided in the mail server. Read / write access of the local file system accesses the mailbox, determines whether there is a mail to be delivered from the mailbox to the remote MUA, and extracts at least one mail from the mailbox if there is a mail to be delivered to the remote MUA. To transmit to the remote MUA. The latest version of the POP daemon is POP3, and the latest version of IMAP is IMAP4.

The remote MUA is a mail client program provided in the mail receiving client terminal. Examples include the Outlook Express of Microsoft, the Netscape Mail of Netscape, and the UNIX "/". usr / ucb / mail ”. Recently, there is a case of using a web browser including Microsoft's Internet Explorer as a remote MUA (for example, Web-based Mail).

The mail system is divided into several small mutually independent components as described above, because various kinds of systems can be obtained through various combinations of various components. Recently commercialized mail servers include a Dispatcher System, a Delivery Interface, a Retrieval Interface, an Authentication System, or a Mailbox Location Search component. A cluster-based mail system, which is further extended to the system, is used, and typical cluster-based mail systems include Duke University's shipping system, EtherLink Network's EtherLink system, Washington's Percupine system or UC Berkeley's NinjaMail system.

However, conventional mail servers and / or mail systems, whether in the form of a single mail server or in a cluster-based fashion, receive mail received by the MTA from another MTA or a given MUA (e.g., mail sent externally or received from outside). And / or access to mail stored in the mailbox via local MDA is only granted to the mail receiving client and / or mail sending client (e.g., mail stored in the sending mailbox), and at least one second client Access to mail is strictly restricted, and if at least one or more second clients access the mail received by the MTA, and / or the mail stored in the mailbox via a local MDA, this is illegal for unauthorized information systems. It is a hack to infiltrate or illegally gain unauthorized privileges.

As described above, in a conventional mail server and / or a mail system, at least one or more second clients strictly restricts access to mail received by the MTA and / or mail stored in a mailbox through a local MDA. It is intended to protect the privacy of the client that owns the mail, and at least one second client's access to the mail is essentially blocked.

An object of the present invention is a mail retrieval method executed by a server, in which a temporarily stored mail is checked before being delivered to a mail receiving side, and a specific keyword is included in or matched with the specific keyword among the checked mails. The present invention provides a mail retrieval method for processing a mail to which a file to be attached is searched, processing to display at least one advertisement content in the searched mail, and processing the processed mail to be delivered to the mail receiving side.

In the mail retrieval method according to the present invention, in a mail retrieval method executed by a server, a step of confirming temporarily stored mail before being delivered to a mail receiving side and including a specific keyword in the body of the mail among the checked mails, or Searching for an e-mail to which a file matching a keyword is attached; and processing at least one advertisement content to be displayed on the searched e-mail, and processing the e-mail to be delivered to the mail receiving side.

In the mail retrieval method according to the present invention, the mail is permitted to search among the temporarily stored mail is characterized in that it further comprises.

In the mail retrieval method according to the invention, characterized in that it further comprises the step of storing the identification information for identifying the searched or processed mail.

In more detail, FIG. 8 has a function of interworking the mail server 200 and a predetermined search server or searching for the storage medium 1 to the storage medium 2, 255 in a predetermined search server. In the case where the search server is provided with a function of searching for at least one or more shared mails shared and stored in the storage medium 1, a web browser provided with at least one second client at a predetermined client terminal 270. Access the search server through 280, search for at least one shared mail shared and stored in the storage medium 1 through a shared mail search function provided in the search server as shown in FIG. This is for remote access to a predetermined shared mail corresponding to a search result.

As shown in (a) of FIG. 9, at least one or more second clients have a search function for the storage medium 1 to storage medium 2, 255 through a web browser 280 provided in the client terminal 270. When accessing the provided search server (800), the at least one or more second client is at least one shared storage in the storage medium (1) as shown in Figure 9 (a) through a predetermined search interface provided by the search server A search word for searching for the shared mail is input and a search for the shared mail corresponding to the search word is requested (805).

As described above, when the client terminal 270 requests a search for a shared mail shared and stored in the storage medium 1 through a predetermined search word, the search server may include the at least one of the shared mails uniquely stored in the storage medium 1. In operation 810, the shared mail is searched for the second client.

Referring to (a) of FIG. 9 according to a preferred embodiment of the present invention, the at least one or more second clients have not logged in to the search server, whereby the search server has mail sharing information as shown in FIG. It is preferable to search for at least one or more shared mails matching the search word input by the at least one or more second clients among the shared mails in which the “search allowed” item is set to allow all search. According to another exemplary embodiment, when the at least one second client logs in to the search server, the search server may allow a “search allowed” item of the mail sharing information among the shared mails stored in the storage medium 1. The shared mail set as and the shared mail which allows the at least one or more second clients to search are searched through the input search word.

In addition, referring to (a) of FIG. 9, when the at least one or more second clients search at least one or more shared mails through the web browser 280, the search target is stored in the storage medium 1. Although the mail is limited to search, according to another exemplary embodiment of the present invention, the search object may be set to at least one search object (eg, “integrated search”) including the search of the shared mail.

If the shared mail corresponding to the search word input by the at least one or more second clients does not exist in the shared mail search result after performing the shared mail search as described above (815), the search server uses the web browser ( The shared mail retrieval error message is transmitted to the client terminal 270 of the at least one second client through the operation 280, and is output (820).

On the other hand, if the shared mail corresponding to the search word input by the at least one or more second clients is present in the shared mail search result (825), the search server is connected through the web browser 280 as shown in (b) of FIG. In operation 830, a predetermined shared mail search result is transmitted to the client terminal 270 of the at least one second client.

The web browser 280 is preferably transmitted to the client terminal 270 of at least one or more second clients according to the format. In the case of (b) of FIG. 9, the shared mail search result uses a search result format of a general search server, but a predetermined bulletin board format or web mail format may be used.

When the shared mail search result is transmitted and output to the client terminal 270 of at least one or more second clients as described above, the search server is included in the search result from the client terminal 270 of the at least one or more second clients. In operation 835, an access request for at least one shared mail is received from the shared mail.

If an access request for at least one or more shared mails among shared mails included in the shared mail search result is received from the client terminal 270 of the at least one or more second clients, the search server may be configured to the at least one or more shared mails. The second client checks whether at least one prerequisite should be performed in order to access the shared mail for which the access is requested (845).

If the at least one second client needs to perform at least one preceding procedure to access the shared mail (850), the mail server 200 performs the at least one prior procedure according to a predefined manner. The second client performs at least one prerequisite for accessing the shared mail (855).

According to one embodiment of the present invention, in order for the at least one or more second clients to access the shared mail, the client sharing the shared mail needs to be approved. In this case, the search server preliminarily performs a process of requesting the client to approve the at least one second client from accessing the shared mail.

For example, the search server may send a message or a message to the client requesting the at least one second client to approve access to the shared mail, or the mobile phone of the client (eg, a search server (or a mail server) 200), if the member information and the mobile phone number is registered) may transmit a message requesting that the at least one second client to approve access to the shared mail, it is usually in the technical field to which the present invention belongs Those skilled in the art will be able to infer implementation methods for the shared mail access approval process through various implementation methods in addition to the above-described implementation method, and the technical idea of the present invention is to infer all types of shared mails that can be inferred as described above. Include how access is enforced.

According to another exemplary embodiment of the present invention, in order for the at least one or more second clients to access the shared mail, a predetermined amount must be paid to the client who shared the shared mail. In this case, the search server preliminarily performs a predetermined payment process for the at least one second client to access the shared mail shared by the client.

For example, the search server performs a predetermined process of paying from the at least one second client to the client a payment amount and / or points corresponding to a predetermined sharing amount presented by the client, and the present invention belongs to. Those skilled in the art will be able to infer various types of shared mail sharing payment methods, including credit card payment, online deposit payment, mobile phone payment, or point payment. As described above, the method of performing shared mail sharing payment of all kinds that can be inferred is included.

The at least one second client completes at least one preceding procedure for accessing the shared mail shared by the client by the at least one second client, or the at least one second client performs the shared mail. If a prerequisite for accessing the request is not required (860), the mail server 200 (or the search server) may allow remote access to at least one shared mail requested by the at least one second client. And to the at least one or more second clients, the shared mail to which access rights are granted in a manner predefined by the mail server 200 and / or a client and / or in a manner requested by the at least one or more second clients. Share (865).

10 is a flowchart illustrating a process of providing a shared mail to which at least one second client is granted access according to an embodiment of the present invention.

In more detail, FIG. 10 illustrates a shared mail in which access rights are granted to at least one or more second clients through the process shown in FIG. 8, and / or the client includes predetermined mail sharing information in the shared mail. In a shared mail to which at least one second client is granted access, the at least one second client accesses and logs in to the mail server 200 (or a search server associated with the mail server 200). This is for the case where the shared mail to which the access right is granted as described above is provided to the at least one second client.

Referring to FIG. 10, at least one second client connects to a search server (or a mail server 200) through a web browser 280 provided in a predetermined client terminal 270 (1000), and FIG. As shown in (a), the user logs in to the search server (or the mail server 200) through the web browser 280 (1005).

When the login to the search server (or the mail server 200) is completed as described above, the search server (or the mail server 200) is the at least one or more second client of the shared mail stored in the storage medium (1) In operation 1010, it is determined whether at least one or more shared mails to which the access right for remote access has been granted are present.

If there is no shared mail accessible by the at least one second client in the determination process (1015), the search server (or the mail server 200) has access right to the at least one second client. The process of enhancing the assigned shared mail is terminated (of course, the conventional mail service or search service is normally provided).

On the other hand, if there is at least one or more shared mails accessible by the at least one second client in the determination process (1020), the search server (or mail server 200) is the web browser as shown in (b) of FIG. In operation 1025, a predetermined mail sharing message for confirming that there is a shared mail accessible to the client terminal 270 of the at least one second client is displayed.

When the mail sharing message is output to the client terminal 270 of at least one or more second clients as described above, the at least one or more second clients are connected to the search server (or the mail server 200) through the web browser 280. Request a predetermined mail access interface corresponding to the mail sharing message (1030).

According to various embodiments of the present disclosure, the mail access interface may be output through the web browser 280 similarly to (b) of FIG. 9, and the mail selection policy of the search server (or the mail server 200) may be used. To the client or at least one or more second clients, the mail access path is predefined, or if the mail sharing message includes an interface for selecting at least one or more mail access paths, the search server (or mail server 200). )) May output a predetermined mail access interface corresponding to the access path to the client terminal 270 of the at least one second client. For example, when the MUA or the instant messenger 285 provided in the client terminal 270 of at least one or more second clients is defined as the mail access path, the search server (or the mail server 200) may be configured as the client. The mail access interface for accessing the shared mail to which at least one second client is granted access is output through the MUA or the instant messenger 285 included in the terminal 270 (1035).

When the predetermined mail access interface is output to the client terminal 270 of the at least one second client as described above, the at least one second client is a search server (or the mail server 200) output to the client terminal 270. Through 1040, access to at least one or more shared mails to which the access right is granted. For example, the at least one second client downloads an attachment included in the shared mail through the mail access interface.

12 is a flowchart illustrating a process of sharing and providing a shared mail to at least one second client by a client according to an exemplary embodiment of the present invention.

In more detail, FIG. 12 illustrates at least one or more items in which the client is given access to mail sharing information on the shared mail in the process of sharing and storing a predetermined shared mail on the storage medium 1. This is a case where an attachment included in the shared mail is shared and provided by an instant messenger 285 provided in a client terminal 270 of two clients.

However, a method of sharing and providing a predetermined shared mail from a client to at least one second client is provided in various implementation methods (for example, the storage medium of the client in the mail server 200 in addition to the method described in FIG. 12). A method of forwarding a shared mail to a mail account of at least one second client from 1) and sharing the mail, or at least one second client stored in the storage medium 1 of the client in the mail server 200. A method of generating network connection information that can access shared mail, transmitting the shared mail to at least one second client, and sharing the shared mail with reference to the network connection information from the at least one second client). It is obvious. In addition, in providing sharing of the shared mail from the client to at least one second client, various implementation methods (for example, the shared mail may be performed in addition to the implementation method of omitting the sharing mail access approval process as in the implementation method shown in FIG. 12). It is apparent that a method of obtaining real-time approval of a client in the process of providing sharing, or a method of obtaining approval using an OTP in the process of providing sharing of a shared mail) may be provided. As a result, the implementation method of FIG. 12 is merely one exemplary implementation method for efficient description among various implementation methods included in the technical idea of the present invention, and the technical idea of the present invention is not limited to the case of this drawing 12. Will be obvious.

Referring to FIG. 12, the client accesses the mail server 200 through the web browser 280 (or MUA) provided in the client terminal 270 (1200), and accesses the shared mail stored in the storage medium 1. By adding the mail sharing information that allows the access of at least one or more second clients (in this case, in the case of Figure 12, the access authorization process is omitted in the process of providing shared mail because the access rights are added to the mail sharing information) At least one second client grants a predetermined access right to access the shared mail (1205), and sets a shared mail providing path for sharing the shared mail to the at least one second client (1210). ).

According to an embodiment of the present invention, a shared mail providing path for sharing and providing the shared mail to at least one second client is a path using a web browser 280 of at least one second client, a path using a MUA, and an instant. There may be a path using the messenger 285, and / or a path using a predetermined communication program 290. In FIG. 12, a shared mail providing path using the instant messenger 285 is used. Of course, when the shared mail providing path is fixed to a specific path, the process of setting the shared mail providing path as described above may be omitted.

If the shared mail providing path is not the instant messenger 285 (1215), the mail server 200 provides the shared mail to the at least one second client through the shared mail providing path set by the client. (1220).

On the other hand, if the shared mail providing path is an instant messenger 285 of at least one or more second clients (1225), the mail server 200 may provide an instant messaging function (eg, the instant messenger 285 of at least one or more second clients). And a function of transmitting an attachment of the main content through a communication port and a communication protocol to be used (1230), and whether the at least one second client is currently using the instant messenger 285 through the instant messaging function. Determine (1235).

If the at least one second client is not currently using the instant messenger 285 (1240), the mail server 200 is configured when the at least one second client uses the instant messenger 285 (e.g., In operation 1245, the at least one second client executes the instant messenger 285 in the client terminal 270 to log in to the instant messaging network.

On the other hand, if the at least one second client is currently using the instant messenger 285 (1250), the mail server 200 extracts an attachment from a shared mail to be shared and provided to the at least one second client. In operation 1260, the attachment of the extracted shared mail is transmitted to the instant messenger 285 of the at least one second client through the activated instant messaging function.

According to a preferred embodiment of the present invention, the method of transmitting the attachment of the shared mail to the instant messenger 285 may be based on a data transmission method based on a communication protocol provided in the instant messenger 285.
