Description

File upload method by extracting folder link from web storage {FILE UPLOADING METHOD BY EXTRACTING FOLDER LINK FOR WEB-STORAGE}

The present invention relates to a method for uploading a file by extracting a folder link of a web storage. More particularly, the link information of an upload folder which can be accessed by a user terminal through the Internet is sent through an e-mail, and the user who receives the e-mail receives a mail. The present invention relates to a method of uploading a file by extracting a folder link of a web storage that allows a user to access a specific folder for uploading a file by clicking the link information inserted in the link.

Web storage refers to a service that receives a file from a user terminal connected through the Internet, stores the file in a mass storage device, and downloads the file by accessing the Internet according to a user's needs.

Recently, due to the development of network access technology and the construction of a communication environment, a web storage service that can be used whenever and wherever the Internet can be used is widely used.

When saving (uploading) a file on web storage, the user who wants to upload the file should access the web storage service site and log in, browse the opened upload folder or the newly created folder, and transfer the desired file. .

However, in the process of working with others, it may be necessary to put files on web storage that you do not use.In this case, it is difficult to know which folder to upload files to even when you access the web storage site. There is.

In particular, even if a user requests upload by specifying a specific folder, if there is a folder with a similar name or the tree structure is complicated, the folder cannot be easily found.

In the case of file download, the user who uploaded the file inserts the link information (URL for accessing a specific file, etc.) about the location where the specific file is stored in the mail or the messenger and sends it to the receiver. Disclosed is a technology that enables users to download a desired file by simply clicking.

Users can easily access files on the web storage site without having to log in and access the file directly in the mail or message display, and can receive the file in a short time.

However, in the case of upload, such a system is not developed, and there is still a problem of having to go through a complicated connection process.

The present invention for solving the above-mentioned problems is to insert the link information for a specific folder of the web storage in the mail or message sent by the user, the user receiving the mail or message clicks the link information in the corresponding folder of the web storage It aims to provide a file upload method by extracting a folder link of web storage that allows a user to upload a file directly.

The present invention for solving the above problems is a method of storing a file in a specific folder of the web storage connected via the Internet, when a link information transmission request for accessing the specific folder from a first user terminal connected through the Internet Extracting link information on the specific folder and transmitting the extracted link information to the first user terminal; When the user who receives the mail or message in which the link information is inserted requests a connection to the specific folder by using a second user terminal, the second user terminal is connected to the specific folder, and the browser of the second user terminal is connected. Displaying a content of the specific folder in a second step; And when the file is transmitted from the second user terminal, storing the transmitted file in the specific folder.

The link information may be a URL (Uniform Resource Locator) for accessing a specific folder opened in the web storage.

The first step further includes encrypting some or all of the link information for accessing the specific folder with an RSA-based public key.

The second step may further include decrypting an encrypted portion of the link information for accessing the specific folder with a public key based on an RSA-based private key.

According to the present invention, there is no need to go through a login procedure and a troublesome folder search process in order to upload a file to the web storage, so that the file can be easily stored.

Hereinafter, a file upload method (hereinafter, referred to as an "upload method") by extracting a folder link of web storage according to an embodiment of the present invention will be described.

1 is a conceptual diagram illustrating a connection state of a system for implementing a file upload method of the present invention.

In order to implement the upload method of the present invention, the first and second user terminals 102 and 104 and the web storage system 200 connected to each other through the Internet are required.

The user terminals 102 and 104 refer to a general PC capable of transmitting and receiving files and using a mail service, and the web storage system 200 refers to a system that provides a file storage and transmission service to a user connected through the Internet.

The web storage system 200 is provided with a large-capacity storage device and a database system for storing files, and includes a configuration for smoothly uploading and downloading files.

In the web storage system 200, a plurality of folders 202 for storing files for each user are created. Each folder 202 is designated and stored with a separate Uniform Resource Locator (URL). Thus, if the user knows the URL for the specific folder 202, the user may directly access the specific folder 202 to upload or download a file.

When the user is registered as a user in the web storage system 200, the file may be uploaded or downloaded through a login process, but the file may be uploaded even when the user is not a registered user. At this time, the registered user (file recipient) should provide information on the folder 202 on which the file can be placed to the unregistered user (file sender).

The information on the folder 202 specifically refers to link information, and the representative link information is a URL for accessing a specific folder 202 through the Internet. In order to improve security in an environment in which link information is transmitted through the Internet, which is an open network, encryption of link information may be performed in parallel.

The first user terminal 102 used by the file receiver transmits link information to the second user terminal 104 used by the file sender. The transmission of link information is inserted into a mail transmitted through an e-mail system and a message transmitted through a messenger system.

The file sender can directly access the folder 202 desired by the file receiver using the link information inserted in the mail or message transmitted from the file receiver, and place the file.

2 is a flowchart illustrating an implementation process of a file upload method.

First, the web storage system 200 is accessed using the first user terminal 102 of the file receiver.

The first user terminal 102 is a terminal on the file receiver side and is generally a user registered in the web storage system 200. The receiver creates a folder in which the file can be placed on the web storage system 200. The web storage system 200 requests link information for accessing the folder 202 created by the user (S104).

The web storage system 200 extracts link information about the specific folder 202 and transmits the link information to the first user terminal 102 (S106).

In order to extract the folder link information, the web storage system 200 generates a DB record including information indicating the location of the folder 202. The DB record may also include authentication information for the specific folder 202 to upload a file by accessing the specific folder 202.

The web storage system 200 may set an expiration date of the validity period of the DB record. When the expiration date has elapsed, access to the specific folder 202 is restricted. The key value of the generated DB record is encrypted with an RSA-based public key, and the web storage system 200 attaches URL information including the encrypted DB record to link information.

The receiver inserts link information in the mail contents while composing the mail or message, and transmits the created mail or message to the sender side (S108).

Link information is inserted in the form of the body of the mail or message, or in the form of a header or attachment. When inserted into the body content, a hyperlink is set so that when the user clicks with the mouse pointer 20 or the like, the hyperlink is directly connected to the predetermined folder 202.

3 is a conceptual diagram showing the configuration of an e-mail in which a folder link is inserted, and shows an insertion state of hyperlinked link information 10.

In the link information, the final address of the folder in which the file is to be stored is preferably recorded.

In addition, when accessing the web storage system 200 by clicking the link information in the mail sent by the recipient of the file, it may be possible to save the file without going through a separate login procedure. In this case, it is preferable to attach the authentication information together in the link information inserted by the receiver so that user authentication and hyperlink connection are simultaneously performed.

The file sender accesses a mail system (not shown) using the second user terminal 104, and opens the received mail or message (S110).

The sender accesses the upload folder 202 by clicking the link information 10 inserted in the mail displayed on the second user terminal 104. (S112)

When the user clicks the link information 10, the second user terminal 104 extracts the URL included in the link information 10 and accesses the corresponding database. Extract the encrypted personal information through URL, decrypt it with RSA-based private key, and extract the corresponding DB record.

The second user terminal 104 accesses the corresponding folder 202 by referring to the DB record corresponding to the key value. In this case, when the expiration date is set in the DB record, the web storage system 200 determines whether the expiration date of the DB record has elapsed, and blocks the access to the folder 202 when the expiration date has elapsed. On the contrary, if it is determined that the expiration date has not elapsed, access to the folder 202 is allowed.

The web storage system 200 allows the connection of the second user terminal 104 in response to the connection request transmitted from the second user terminal 104, and the specific folder 202 in the browser of the second user terminal 104. Display the contents. The file sender may determine whether the file to be uploaded is stored in the correct folder 202 by referring to the contents of the file stored in the folder 202.

The file sender puts a specific file inside the folder 202 and releases the connection, thereby completing the file uploading procedure (S114).
