Cloud Computing is a combination of various computing concepts such as virtualization computing, utility computing, and on-demand computing, and Internet communication technology. It refers to a technology that implements one virtual computer or service and provides a variety of software, security solutions, and computing capabilities on demand by a user accessing the same.

In other words, cloud computing is an 'on-demand outsourcing service of IT resources through the Internet'.It stores programs or documents that are individually installed or stored on a personal computer or a server of a company in an internet-based virtual server or storage, By running a cloud application using various terminals including a computer, the user can perform a desired task.

Therefore, according to the cloud computing service, users can access the cloud network through a terminal capable of accessing the network at any place and perform tasks requiring a large amount of storage and high performance computing resources. You can also share it.

In another aspect, the utility of cloud computing services is largely a backup space service function that allows users to store any type of data (documents, music, videos, applications, folders, etc.) in individual spaces in the cloud, It can be categorized into N screen service function that allows users to access and use data stored in individual spaces regardless of types, and shared service function that allows users to share data stored in individual spaces with other users. In particular, as cloud computing services spread and their utilization increases, requirements for storing data in cloud space and sharing data stored in cloud space with other users are increasing.

In general, the data stored in the cloud space is shared by setting a specific folder in the cloud space in advance and granting access rights to the users, and then only the users with the access rights can access the shared folder. Sharing data with other users is widely used. This method is suitable when data sharing is planned in advance. When data sharing is not planned in advance and is requested at an unexpected time, it is mainly used to share data using e-mail or user terminal from the cloud. It is common to download the data directly and share it with the other party.

Meanwhile, as wired and wireless networks become more advanced and performance of user terminals improves, sharing of large amounts of data such as music, movies, and games is required. Recently, not only data but also platforms, applications, or applications required to run apps (applications) are required. Even the service itself is provided through the cloud. In sharing such a large amount of data, the sharing method, especially when not planned in advance, has a problem due to the size of the data, and therefore, a method for more convenient and safe sharing of a large amount of data and apps is urgently required.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily carry out the technical idea of the present invention. In the following description of the preferred embodiments of the present invention, when it is determined that the detailed description of the related known technology may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted or briefly described.

1 is a view schematically showing a cloud service environment to which the present invention is applied.

As shown in FIG. 1, a first user and a second user access a cloud through a wired / wireless internet using a terminal such as a smart phone / PC / laptop / tablet anywhere and provide a large storage space service provided by the cloud. It is available.

Here, the cloud may provide various types of services according to the purpose and scope of use, but in the present invention, among the various services of the cloud, the user may use any form of data (documents, music, videos, applications, folders, etc.) in individual spaces. Backup space service function that allows users to save data, N screen service function that allows users to access and use data stored in individual spaces regardless of the type of device anytime, anywhere, and users can share data stored in individual spaces with other users. It focuses on the shared services that make it possible.

That is, the present invention is characterized in that a user can share data stored in his or her space with another user anytime, anywhere using his terminal even when data and app sharing is not planned in advance. In the description of the cloud computing based data sharing method according to the present invention will be described in more detail.

2A and 2B are flowcharts illustrating a data sharing method based on cloud computing according to an embodiment of the present invention.

For convenience of description, when the first user accesses the cloud using the first user terminal and sets data stored in his storage as shared data, the second user accesses the cloud using the second user terminal to access the shared data. An example of accessing to is described.

First, referring to FIG. 2A, a cloud access program is executed in a first user terminal by a first user so that the first user terminal is connected to the cloud (S201).

Next, when shared data is set among the data stored in the space of the first user in the cloud through the first user terminal according to the input of the first user (S202), the cloud provides metadata necessary for accessing the shared data to the first user terminal. It transmits to the user terminal (S203).

Here, the metadata includes a cloud ID of the first user, access authority information (authentication key) for the shared data, a location of the shared data, a file name, and the like.

Next, the direct sharing method or the indirect sharing method is selected according to whether the first user terminal is close to the second user terminal (S204).

In more detail, the direct sharing method is selected when the first user terminal can be approached to the second user terminal, and the indirect sharing method is selected when the first user terminal cannot be approached by the second user terminal. do.

When the first user terminal is close to the second user terminal in the state in which the direct sharing method is selected (S205), the first user terminal receives the first user terminal from the second user terminal using NFC (Near Field Communication), which is one of near field communication technologies. 2, user information (telephone number, cloud ID, etc. of the second user) is received (S206).

Here, NFC is a kind of peer-to-peer (P2P) sharing method, and refers to a technology for transmitting data between terminals at a close distance of about 10 cm using a contactless short-range wireless communication module using a 13.56 Mz frequency band. Since the technology can be easily understood by those skilled in the art, a detailed description thereof will be omitted.

Then, the first user terminal transmits the metadata to the second user terminal using NFC (S207), and thus the second user terminal also receives the metadata from the first user terminal using NFC ( S208).

Here, the metadata includes the cloud ID of the first user who is the sender, access authority information (authentication key) for the shared data, the location and file name of the shared data, and the like.

Next, the data sharing request is requested from the first user terminal to the cloud (S209).

In this case, when the data sharing request is made to the cloud, the first user terminal also transmits the information of the second user (phone number, cloud ID of the second user, etc.) and information on the shared data, so that the second user terminal may be added later. When the client accesses the shared data and accesses the cloud, the cloud may authenticate the access right of the second user terminal.

Next, the cloud allows the second user terminal to access the shared data according to the data sharing request from the first user terminal (S210), and the method for allowing access to the shared data in the cloud will be described in more detail below. Let's explain.

Next, the cloud access program is executed in the second user terminal by the second user so that the second user terminal is connected to the cloud (S211).

Next, the second user terminal accesses and shares the shared data using access authority information (authentication key), location of the shared data, and file name of the shared data included in the meta data (S212).

Meanwhile, referring to FIG. 2B, when an indirect sharing method is selected because the first user terminal cannot be brought close to the second user terminal, the first user terminal uses the second user terminal based on the metadata and the information of the second user. A sharing request message to be sent is generated (S213).

Here, the sharing request message includes a cloud ID of the first user, a cloud ID of the second user, access authority information (authentication key) for the shared data, a location and file name of the shared data, and the like.

Next, when the first user terminal transmits the generated sharing request message to the second user terminal using a text message (SMS), a multimedia message (MMS), or an e-mail (S214), the second user. The terminal also receives the sharing request message from the first user terminal by using a text message (SMS), a multimedia message (MMS) or an e-mail (S215).

Next, the data sharing request is requested from the first user terminal to the cloud (S216), and the cloud allows the second user terminal to access the shared data according to the data sharing request from the first user terminal (S217). Here, a method of allowing access to shared data in the cloud will be described in more detail below.

Next, the cloud access program is executed in the second user terminal by the second user, and the second user terminal is connected to the cloud (S218).

Next, the second user terminal accesses and shares the shared data using the access right information (authentication key), the location of the shared data, and the file name of the shared data included in the sharing request message (S219).

3A to 3C are diagrams for describing a method for allowing access to shared data in a cloud applied to the present invention.

First, referring to FIG. 3A, when data sharing is requested from the first user terminal to the cloud, the cloud copies data stored in the space of the first user to the space of the second user. Will be able to access and share the data copied into its own space.

Next, referring to FIG. 3B, when the sharing of data is requested from the first user terminal to the cloud, the cloud updates the access right of the second user to access the space of the first user. The terminal may access and share data stored in the space of the first user.

Next, referring to FIG. 3C, when data sharing is requested from the first user terminal to the cloud, the cloud may copy data stored in the space of the first user to a predetermined shared space and access the shared space. The access rights of the second user are updated so that the second user terminal can access and share the data stored in the shared space.

This method is suitable when the data sharing is planned in advance. The public space is set up for the purpose of sharing in advance, and only the users who have access to the shared space can access the data. To share with others.

Here, the shared space may be used by setting some folders of the user's space as the shared space, or by setting the shared space as an open space occupied and managed by the cloud for sharing purposes.

As described above, in the case of sharing data using the shared space, not only can the cloud space be efficiently used, but also the user's cloud space can be prevented from being invaded by unexpected accidents and hacking. In addition, even if the data is copied to the shared space only once, there is an advantage in that a plurality of user terminals can access and share the data. However, even when using a shared space, it is desirable to manage access rights so that proper protection and sharing can be achieved.

As described above, according to the present invention, data stored in the cloud can be easily shared through a peer-to-peer method between a terminal and a terminal using a near field communication (NFC) method. In addition, direct transmission of a large amount of shared data via wireless communication may cause problems such as overload of radio resources and insufficient memory in the user terminal. However, according to the present invention, the shared data may be accessed instead of the actual method of transmitting the shared data. Since only meta data exists, only the information can be solved.

That is, according to the present invention, even when the sharing of data and apps is not planned in advance, a user can share data with other users through the cloud anytime, anywhere using his terminal, and also need to share data In this case, only metadata required for data sharing, not actual data, is quickly transmitted to another user's terminal so that data can be shared regardless of the size of the actual data.

In the present embodiment, the first user terminal has been described for transmitting the metadata or the sharing request message to the second user terminal, but it is also possible to transmit the metadata or the sharing request message from the first user terminal to the terminals of several users. Of course.

In the present embodiment, the meta data is transmitted by using a text message (SMS), a multimedia message (MMS), or an e-mail when the first user terminal and the second user terminal are not in close proximity. In some cases, even when the first user terminal and the second user terminal are in close proximity, the metadata may be transmitted using a text message (SMS), a multimedia message (MMS), or an e-mail.

In addition, in the present exemplary embodiment, only meta data required for sharing data, not actual data, is transmitted to the second user terminal. However, in some cases, the first user terminal accesses the cloud and downloads the shared data, Bring the user terminal closer to the second user terminal to send the actual shared data to the second user terminal using NFC, or use the text message (SMS), multimedia message (MMS) or e-mail (E-mail) May be transmitted to the second user terminal.

Meanwhile, with the proliferation of smart terminals (smartphones, tablets, smart TVs, etc.), various applications (hereinafter referred to as 'apps') that are executed on smart terminals are widely supplied through the app store.

However, in the past, there is no sharing service that allows a user to share an downloaded app with other users. Accordingly, in order to share an app, a user may inform another user of the app name and a second user may You have to go through the process of searching for and downloading the app. However, in this case, if the name of the app is not correct, it takes a long time to share the app, which is inconvenient in terms of users.

To this end, in the present invention, it is possible to share the app downloaded to the smart terminal with other users using the cloud, which will be described in more detail as follows.

4A and 4B are flowcharts illustrating a cloud computing based app sharing method according to an embodiment of the present invention.

First, referring to FIG. 4A, when a first user terminal accesses an app store (S401), and downloads an app (S402), the app store transmits the downloaded app to the cloud (S403), and the app downloaded from the cloud. This is stored in the space of the first user (S404).

For example, when an app called "KAKAOTALK" is downloaded to a first user terminal, the cloud stores an app called "KAKAOTALK" in a folder called App / in the first user space.

Next, when the first user terminal accesses the cloud according to the input of the first user (S405), and sets the shared app among the apps stored in the space of the first user in the cloud (S406), the cloud downloads the shared app. The necessary meta data is transmitted to the first user terminal (S407).

Here, the metadata includes a cloud ID of the first user, access right information (authentication key) for the shared app, a location and file name of the shared app, and the like.

Next, the direct sharing method or the indirect sharing method is selected according to whether the first user terminal is close to the second user terminal (S408).

When the first user terminal is close to the second user terminal in the state in which the direct sharing method is selected (S409), the first user terminal uses the NFC to transmit information (phone number, second user) from the second user terminal. Cloud ID) and the like (S410).

Next, the first user terminal transmits the metadata to the second user terminal using NFC (S411), and the second user terminal also receives the metadata from the first user terminal using NFC (S412). .

Next, the first user terminal requests to share an app to the cloud (S413).

Here, when requesting the app sharing to the cloud, the first user terminal also transmits the information of the second user (phone number, cloud ID of the second user, etc.) and information about the shared app, so that the second user terminal can be When the user accesses the shared app by accessing the cloud, the cloud may authenticate the access right of the second user terminal.

Next, in the cloud, according to the mutual agreement result of the app sharing between the cloud operator and the app store operator, the app push method (A) is performed to push the shared app to the second user terminal (S414), or the app sharing method (B). To allow access of the second user terminal to the shared app (S415 to S417).

First, in the case of the app push method (A), the cloud immediately pushes the shared app to the second user terminal according to the app sharing request from the first user terminal (S414). In this case, instead of directly pushing the shared app to the second user terminal, the cloud may copy and store the shared app in the cloud space or the shared space of the second user and then push the shared app.

In the case of the app sharing method (B), the cloud allows the second user terminal to access the shared app by copying and storing the shared app in the cloud space or the shared space of the second user (S415). Next, when the second user terminal is connected to the cloud (S416), the second user terminal accesses the access authority information (authentication key) for the shared app included in the metadata, using the location and file name of the shared app. Access to download the shared app (S417).

Meanwhile, referring to FIG. 4B, when an indirect sharing method is selected because the first user terminal cannot be brought close to the second user terminal, the first user terminal uses the second user terminal based on the metadata and the information of the second user. A share request message to be sent is generated (S418).

Here, the sharing request message includes a cloud ID of the first user, a cloud ID of the second user, access authority information (authentication key) for the shared app, a location and file name of the shared app, and the like.

Next, when the first user terminal transmits the generated sharing request message to the second user terminal using a text message (SMS), a multimedia message (MMS), or an e-mail (S419), the second user The terminal also receives the sharing request message from the first user terminal by using a text message (SMS), a multimedia message (MMS) or an e-mail (S420).

Next, when the first user terminal requests the app sharing from the cloud (S421), the cloud performs the app push method (A) according to the mutual agreement result of the app sharing between the cloud operator and the app store operator to release the shared app. 2 to the user terminal (S422), or by performing the app sharing method (B) allows the second user terminal access to the shared app (S423 ~ S425).

First, in the case of the app push method (A), the cloud directly pushes the shared app to the second user terminal according to the app sharing request from the first user terminal (S422). In this case, instead of directly pushing the shared app to the second user terminal, the cloud may copy and store the shared app in the cloud space or the shared space of the second user and then push the shared app.

In the case of the app sharing method (B), the cloud allows the second user terminal to access the shared app by copying and storing the shared app in the cloud space or the shared space of the second user (S423). Next, when the second user terminal is connected to the cloud (S424), the second user terminal shares the access authority information (authentication key) for the shared app included in the sharing request message by using the location and file name of the shared app. Access to the app to download the shared app (S425).

That is, in the data sharing method illustrated in FIGS. 4A and 4B, when an app is downloaded from the app store to the first user terminal, the downloaded app itself is copied to the cloud so that the second user terminal can share it.

5A and 5B are flowcharts illustrating an app sharing method based on cloud computing according to another exemplary embodiment of the present invention.

First, referring to FIG. 5A, when a first user terminal accesses an app store (S501) and downloads an app (S502), the app store transmits information of the downloaded app to the cloud (S503), and downloads from the cloud. The stored information of the app is stored in the space of the first user (S504).

For example, when an app called "NOTE" is downloaded to the first user terminal, the cloud stores the location and file name of the app called "NOTE" in a folder called Appinfo / in the first user space.

Next, when the first user terminal accesses the cloud according to the input of the first user (S505), and sets the shared app among the apps stored in the space of the first user in the cloud (S506), the cloud downloads the shared app. The necessary metadata is transmitted to the first user terminal (S507).

Here, the metadata includes a cloud ID of the first user, access right information (authentication key) for the shared app, a location and file name of the shared app, and the like.

Next, the direct sharing method or the indirect sharing method is selected according to whether the first user terminal is close to the second user terminal (S508).

When the direct sharing method is selected, when the first user terminal is close to the second user terminal (S509), the first user terminal uses NFC to transmit information (phone number, second user) from the second user terminal. Cloud ID and the like) (S510).

Next, when the first user terminal transmits the metadata to the second user terminal using NFC (S511), the second user terminal also receives the metadata from the first user terminal using NFC (S512). .

Here, the metadata includes a cloud ID of a first user who is a sender, a cloud ID of a second user who is a receiver, access authority information (authentication key) for a shared app, a location and a file name of a shared app, and the like.

Next, the first user terminal requests to share an app to the cloud (S513).

Here, when requesting the app sharing to the cloud, the first user terminal also transmits the information of the first user, the information of the second user (phone number, cloud ID, etc.) and the information on the shared app, so that the second When the user terminal accesses the shared app by accessing the cloud, the cloud may authenticate the access right of the second user terminal.

When the app sharing is requested from the first user terminal, the cloud performs an app push method (A) or a direct app push method (B) through the app store according to a mutual agreement result of app sharing between the cloud operator and the app store operator. The shared app is pushed to the second user terminal (S514 to S515, S516 to S518), or the second user terminal is allowed to access the shared app by performing the app sharing scheme C (S519 to S523).

First, in the case of the app push method (A) through the app store, in the cloud, information of a second user who is a receiver together with information of a shared app stored in a space of the first user according to an app sharing request from the first user terminal Request the app push while transmitting to the app store (S514), the app store searches for the shared app based on the information of the shared app received according to the app push request from the cloud, and pushes the found shared app to the second user terminal. (S515).

In the case of the direct app push method (B), the cloud requests a patch of the shared app while transmitting information of the shared app stored in the space of the first user to the app store according to an app sharing request from the first user terminal. In operation S516, the shared app is patched from the app store (S517), and the patched shared app is directly pushed to the second user terminal (S518).

In the case of the app sharing method (C), the cloud requests a patch of the shared app to the app store (S519), patches the shared app from the app store (S520), and then applies the patched shared app to the second user. Copying and storing in a cloud space or a shared space allows a second user terminal to access the patched shared app (S521). Next, when the second user terminal is connected to the cloud (S522), the second user terminal accesses the shared access information (authentication key) for the shared app included in the metadata, using the location and file name of the shared app. Access to download the shared app (S523).

Meanwhile, referring to FIG. 5B, when an indirect sharing method is selected because the first user terminal cannot be brought close to the second user terminal, the first user terminal uses the second user terminal based on the metadata and the information of the second user. A share request message to be sent is generated (S524).

Here, the sharing request message includes a cloud ID of a first user who is a sender, a cloud ID of a second user who is a receiver, access authority information (authentication key) for a shared app, a location and a file name of a shared app, and the like.

Next, when the first user terminal transmits the generated sharing request message to the second user terminal using a text message (SMS), a multimedia message (MMS), or an e-mail (S525), the second user. The terminal also receives the sharing request message from the first user terminal by using a text message (SMS), a multimedia message (MMS) or an e-mail (S526).

Next, the first user terminal requests to share an app to the cloud (S527).

Here, when requesting sharing of the app to the cloud, the first user terminal transmits the information of the first user and the information of the second user (phone number, cloud ID, etc.) together with the information of the sharing app, and the second user later. When the terminal accesses the shared app by accessing the cloud, the cloud may authenticate the access right of the second user terminal.

When the app sharing is requested from the first user terminal, the cloud performs an app push method (A) or a direct app push method (B) through the app store according to a mutual agreement result of app sharing between the cloud operator and the app store operator. Push the shared app to the second user terminal (S528 ~ S529, S530 ~ S532), or performs the app sharing method (C) to allow the second user terminal to access the shared app (S533 ~ S537).

First, in the case of the app push method (A) through the app store, in the cloud, information of a second user who is a receiver together with information of a shared app stored in a space of the first user according to an app sharing request from the first user terminal Request the app push while transmitting to the app store (S528), accordingly, the app store searches for the shared app based on the information of the shared app received from the cloud and pushes the retrieved shared app to the second user terminal (S529). .
