Hereinafter, an apparatus and method for updating an application program according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to or limited by the embodiments. Like reference symbols in the drawings denote like elements.

The device-to-device file transmission / reception system according to an embodiment of the present invention can be implemented as an application (program) in a device such as a smart phone, a tablet PC, a laptop computer, a desktop computer, or the like.

Here, each device is connected through a same local network (e.g., a home network, a corporate intranet, a wireless local area network, or the like), and a transmitter or a transmitter that transmits the stored file to another device Lt; RTI ID = 0.0 > a < / RTI > file.

The device-to-device file transmission / reception system of the present invention can perform file exchange without pre-registration of the device between a receiver and a transmitter connected through a local network.

1 is a diagram illustrating a connection relationship between a receiver and a transmitter including an apparatus-to-apparatus file transmission / reception system according to an embodiment of the present invention.

Referring to FIG. 1, the device-to-device file transmission / reception system according to an embodiment of the present invention includes devices (101, 102, 103, 104) connected to the same local network in the form of applications (programs) Can be performed.

Specifically, the device-to-device file transmission / reception system transmits a file exchange command to a device (hereinafter referred to as a receiver) 101 and another device (hereinafter referred to as a " Identifies a first transmitter 102,103 having a receive file associated with the file exchange command among the first sender 102,103,104 and transmits a file exchange command (" file receipt ") to each of the first transmitters 102,103 .

For example, if the file exchange command relates to a sole reception, the device-to-device file transmission / reception system may further transmit the device designation command to any one of the first transmitters 102 and 103.

For example, the device-to-device file transmission / reception system may transmit a device designation command to any one of the first transmitters 102 and 103, or may transmit a device designation command to any one of the first transmitters 102 and 103, Or may select the first transmitter 102 whose connection time to the local network is higher than that to transmit the device designation command.

At this time, the receiver 101 can maintain the authentication information with respect to the second transmitter 102 that has transmitted the device designation command. Also, the second transmitter 102 may generate authentication information about the received file. The device file transmission and reception system transmits the authentication information held in the receiver 101 to the second transmitter 102 together with the device designation command so as to allow the second transmitter 102 to determine whether the authentication information is matched Accordingly, it is possible to determine the transmission of the received file to the receiver 101.

The inter-device file transmission / reception system can receive the reception file held by the second transmitter 102 from the second transmitter 102 responding to the device designation command.

At this time, the device file transmission / reception system invalidates (removes) the received file if the authentication information received from the second transmitter 102 together with the received file does not match the authentication information held in the receiver 101 If the authentication information received from the second transmitter 102 is matched with the authentication information held in the receiver 101, the received received file can be stored in the received file storage in the receiver 101.

Thus, the device-to-device file transmission / reception system is capable of transferring the received file (s) of a specific transmitter 102 among the transmitters 102, 103, and 104 connected to the receiver 101 without specifying a file exchange object (transmitter) by the user of the receiver 101 Can be easily received by the receiver (101).

On the other hand, in the case where the authentication information about the received file is not separately received from the second transmitter 102, the device file transmission / reception system stores the received file as it is in the received file storage box in the receiver 101, It is possible to support free file transmission / reception between all devices connected to the local network.

In another example, if the file exchange command is associated with a joint reception, the inter-device file transmission / reception system further transmits the device designation command to each of the first transmitters 102 and 103, When the received files are received from the transmitters 102 and 103, if the received files are the same, the received files received relatively later can be invalidated.

Accordingly, the file transmission / reception system between devices can easily transmit or receive a file without performing a pre-registration process between different devices owned by an individual, but can perform a simple file exchange by omitting the specification process of a separate file exchange object can do.

FIG. 2 is a diagram illustrating an internal configuration of a device file transmission / reception system according to an embodiment of the present invention.

Referring to FIG. 2, the inter-device file transmission / reception system 200 according to an exemplary embodiment of the present invention may include an identification unit 210, a transmission unit 220, and a reception unit 230. In addition, according to the embodiment, the device-to-device file transmission / reception system 200 can be configured by adding a connection unit 240, an identification unit 250, and a storage unit 260, respectively.

The identification unit 210 identifies a first transmitter having a reception file associated with the file exchange command among a transmitter connected to a receiver in which a file exchange command ('file reception') occurs.

In the present invention, the receiver and the transmitter are devices such as a smart phone, a tablet PC, a laptop computer, a desktop computer, etc., connected to the same local network. The receiver is a device that receives a file (received file) from another device. The device-to-device file transmission / reception system 200 of the present invention can be included in each device in the form of an application and can exchange files between the receiver and the transmitter.

For example, referring to FIG. 3, when the receiver 301 receives a file exchange command related to 'file reception', the identification unit 210 transmits the files 301, 302, 303, 304, and 305 (302, 303, 304) having received files (306, 308, 310) associated with the file exchange command.

According to an embodiment, the connection unit 240 functions to connect the receiver to an established local network (e.g., a home network, a corporate intranet, a wireless local area network, etc.) in conjunction with the input of the file exchange command. The identification unit 210 may identify, based on the connection, at least one first transmitter connected to the local network. In this case, the receiver maintains the disconnection state from the local network before the file exchange command is generated, and can communicate with the local network only when receiving the file.

The transmitting unit 220 transmits a file exchange command to each of the first transmitters and, if the file exchange command is related to the exclusive reception, transmits a device designation command to any one of the first transmitters.

For example, referring to FIG. 3, the transmitter 220 may transmit a file exchange command to each of the first transmitters 302, 303, and 304. At this time, if the file exchange command is related to the single reception, the transmission unit 220 can further transmit the device designation command to any one of the first transmitters 302, 303, and 304.

Here, the transmitter 220 may transmit the device designation command to any one of the first transmitters 302, 303, and 304, and may transmit the device designation command to the first transmitter 302, The device designation command may be transmitted to the device 302 whose connection timing is earlier than that of the device designation command.

The receiving unit 230 receives the received file from a second transmitter that responds to the device designation command.

For example, the second transmitter generates authentication information on the received file, and the transmitting unit 220 transmits the authentication information held in the receiver together with the device designation command to the second transmitter, 2 transmitter to determine the transmission of the received file to the receiver according to whether the authentication information is matched with each other.

For example, referring to FIG. 3, the second transmitter 302 responding to the device designation command may generate authentication information '5AB * 1' 307 for the received file 306. Also, the receiver 301 may maintain the authentication information 312 for the second transmitter 302 that transmitted the device designation command. The transmitting unit 220 may transmit the authentication information 312 held in the receiver 301 to the second transmitter 302 together with the device designation command. The second transmitter 302 may determine the transmission of the received file 306 if the authentication information 312 and the authentication information '5AB * 1' 307 are matched.

In another example, the receiver maintains authentication information for the second transmitter that has transmitted the device designation command, and the receiver 230 receives, from the second transmitter, authentication information received together with the received file, The received file can be invalidated if it does not match the authentication information held in the received file.

3, the receiving unit 230 receives the authentication information '5AB * 1' 307 received together with the received file 306 from the second transmitter 302 in the receiver 301 If it does not match the authentication information 312, the received file 306 can be removed.

The apparatus-to-apparatus file transmission / reception system 200 of the present invention can transmit and receive data to and from a specific one of the transmitters 302, 303, and 304 connected to the receiver 301 without specifying a file exchange object (transmitter) 302) can be easily received by the receiver (301). That is, the receiver is able to receive the received file 306 from a particular transmitter 'tablet PC' 302 among the transmitters 302 and 303 having the same received file 'file A' 306, 308.

The storage unit 260 stores the received file transmitted by the second transmitter in the receiver when the authentication information is not received from the second transmitter.

In other words, if the authentication information is not separately received from the second transmitter, the receiving unit 230 can receive the receiving file from each transmitter having the receiving file associated with the file exchange command, and not the specific transmitter, 260 may store the received file in the received file storage in the receiver.

According to the storage, the receiver 230 notifies completion of the reception to the second transmitter, so that the received file stored in the transmission file storage box of the second transmitter and the authentication information about the received file are deleted.

In another example, if the file exchange command is associated with the joint reception, the transmitting unit 220 further transmits the device designation command to a plurality of devices among the first transmitters, and the receiving unit 230 transmits the device designation command to the device designation command Receiving the received file from a plurality of responding second transmitters, and invalidating the received file relatively later if the received files are the same.

For example, referring to FIG. 3, the transmitter 220 may further transmit a device designation command to each of the first transmitters 302, 303, and 304 if the file exchange command is associated with a joint reception. The receiving unit 230 can receive the receiving files 306, 308 and 310 from the second transmitters 302, 303 and 304 responding to the device designation command and if the received files 'file A' 306 and 308 are identical, The receiving file 308 can be removed. In this case, the storage unit 260 may store the received file 'file A' 306 from the second transmitter 302, which has a relatively high communication speed with the receiver, in the received file storage in the receiver.

At this time, each of the second transmitters 302, 303, and 304 responding to the device designation command can maintain the authentication information 307, 309, and 311 related to the received files 306, 308, and 310. The transmitting unit 220 transmits the authentication information 312 retained in the receiver 301 to the second transmitter 302,303 and 304 together with the device designation command and transmits the authentication information '5AB * 1 At the second transmitter 302, which maintains the '307'.

According to an embodiment, the apparatus-to-apparatus file transmission / reception system 200 may further include an identification unit 250.

The verification unit 250 checks whether the received file is stored in the transmission file storage box of the second transmitter. At this time, if it is confirmed that the received file is not stored in the transmission file storage, the transmission unit 220 can retransmit the device designation command to any one of the first transmitters except for the second transmitter. Alternatively, the receiving unit 230 may receive the receiving file after waiting for the receiving file to be stored in the transmitting file storage through the confirming unit 250. [

For example, referring to FIG. 3, the verifying unit 250 can check whether the received file 'file A' 306 is stored in the transmission file storage in the second transmitter 302 responding to the device designation command have.

If it is confirmed that the received file 306 is not held in the transmission file storage, the transmitting unit 220 transmits the arbitrary device 'tablet PC' 303 of the first transmitter 303 and 304, except for the second transmitter 302, The device designation command can be retransmitted. The receiving unit 230 may receive the received file 'file A' 308 from the 'tablet PC' 303 responding to the device designation command.

In the present invention, 'authentication information' can be selected and used according to the needs of the user of the device.

For example, when the inter-device file transmission / reception system 200 is installed in an application form in each device (receiver, transmitter), the inter-device file transmission / reception system 200 transmits the authentication information For example, 'password', 'user's face image', etc.) in the memory space of each device, and can use the authentication information every time a file is exchanged between devices. That is, the device-to-device file transmission / reception system 200 can collectively give the same authentication information to all files to be transmitted or received between the devices.

Alternatively, the device-to-device file transmission / reception system 200 may use authentication information input from a user of each device when transmitting / receiving a file between a receiver and a transmitter, as authentication information specific to transmission / reception of the file.

Alternatively, the inter-device file transmission / reception system 200 may exchange files without authentication information between the receiver and the transmitter. In this case, the device-to-device file transmission / reception system 200 may transmit a received file from a transmitter that desires to transmit a file to a receiver that desires to receive the file among devices connected to the local network, without matching the authentication information.

That is, the device-to-device file transmission / reception system 200 can selectively use the authentication information only when transmitting a file to a specific receiver or receiving a file from a specific transmitter among devices connected to the local network.

As described above, according to an embodiment of the present invention, a file exchange command is transmitted to each first transmitter having a reception file among transmitters connected to a receiver in which a file exchange command is generated, If it is related to the first transmitter, transmits a device designation command to any one of the first transmitters and receives the received file from a second transmitter responding to the device designation command, It can support free file transmission and reception.

According to an embodiment of the present invention, authentication information is maintained for a second transmitter that has transmitted the device designation command, authentication information received from the second transmitter together with the received file is matched with the held The received file is invalidated, and if the received file is matched, the received file is stored in the received file archive, so that the devices connected to the local network through real-time authentication can send and receive files without a pre-registration procedure.

Also, according to an embodiment of the present invention, it is possible to easily receive a received file of a specific transmitter among transmitters connected to the receiver, without specifying a file exchange object (transmitter) by a user of the receiver.

In addition, according to an embodiment of the present invention, it is possible to transmit a transmission file held by a transmitter to a specific receiver among receivers connected to the transmitter while omitting the process of specifying a file exchange object (receiver) by a user of the transmitter , It is possible to simplify file transmission between devices.

Also, according to an embodiment of the present invention, it is possible to communicate with a local network only when a receiver file is requested by a receiver, and receive a received file from a transmitter, without having to monitor the local network at all times for file transmission and reception between devices .

3 is a diagram for explaining a process of receiving a received file from a specific transmitter among transmitters connected to a receiver in a device-to-device file transmission / reception system according to an embodiment of the present invention.

Referring to FIG. 3, the device-to-device file transmission / reception system according to an embodiment of the present invention includes devices that are connected to the same local network and exchange files, for example, smartphones 301 and 302, tablet PCs 303 and 305, Computer 304 or the like. Here, a device that desires to receive a file may be referred to as a receiver 301, and a device that desires to transmit a file may be referred to as a transmitter 302, 303, 304.

The device file transmission / reception system may be configured to transmit the file exchange command among the devices 302, 303, 304, and 305 connected to the receiver 301 via the local network in response to a file exchange command regarding 'file reception' 302, 303, 304 with the received files 306, 308, 310, respectively.

For example, if the file exchange command relates to 'single reception', the device file transmission / reception system further transmits a device designation command to any one of the first transmitters 302, 303 and 304, From the second transmitter 302 that responds to the received file 'file A' 306.

At this time, the device-to-device file transmission / reception system transmits the authentication information 312 held in the receiver 301 to the second transmitter 302 together with the device designation command, and transmits the authentication information 312 generated by the second transmitter 302 The second transmitter 302 may transmit the received file 'file A' 306 to the receiver 301 as the authentication information 307 matches the authentication information 312.

The device-to-device file transmission / reception system may also be configured such that the authentication information '5AB * 1' 307 received together with the received file 306 from the second transmitter 302 includes authentication information 312 held in the receiver 301 If they do not match, the received file 306 may be removed.

In another example, if the file exchange command is associated with a joint reception, the inter-device file transmission / reception system 200 further transmits a device designation command to each of the first transmitters 302, 303, and 304, 308 and 310 from each of the transmitters 302,303 and 304 and if the received file 'file A' 306 and 308 are identical, it is possible to remove the received file 308 received relatively later. Accordingly, the inter-device file transmission / reception system 200 can store the received file 'file A' 306 from the second transmitter 302, which has a relatively high communication speed with the receiver, in the received file storage box in the receiver .

Each of the second transmitters 302, 303, and 304 responding to the device designation command can maintain authentication information 307, 309 and 311 related to the received files 306, 308 and 310, and the device file transmission / reception system 200, , A second transmitter 302 (not shown) that transmits authentication information 312 maintained in the receiver 301 to the second transmitter 302, 303, 304 to maintain authentication information '5AB * 1' 307 matching the authentication information 312 , It is possible to transmit the received file 306. [

The apparatus-to-apparatus file transmission / reception system 200 of the present invention can transmit and receive data to and from a specific one of the transmitters 302, 303, and 304 connected to the receiver 301 without specifying a file exchange object (transmitter) 302) can be easily received by the receiver (301).

That is, the receiver 301 can receive the received file 306 from the specific transmitter 'tablet PC' 302 among the transmitters 302 and 303 having the same received file 'file A' 306 and 308.

Hereinafter, the operation flow of the inter-device file transmission / reception system 200 according to the embodiments of the present invention will be described in detail with reference to FIG.

The second transmitter 302 may determine the transmission of the received file 306 to the receiver 301 if the authentication information 312 and the authentication information '5AB * 1' 307 match.

The device-to-device file transmission / reception system 200 also transmits the authentication information '5AB * 1' 307 received together with the received file 306 from the second transmitter 302 to the authentication information 312 The received file 306 can be removed.

As described above, according to the present invention, it is possible to easily receive a received file of a specific transmitter among transmitters connected to the receiver, without specifying a file exchange object (transmitter) by a user of the receiver. That is, the receiver can selectively receive a received file from a specific transmitter 'tablet PC' among transmitters having the same received file, without specifying a transmitter separately.

Likewise, according to the present invention, it is possible to easily transmit a transmission file to a specific one of receivers connected to the transmitter without specifying a file exchange object (receiver) by a user of the transmitter.

5 is a flowchart illustrating a procedure of a method for transmitting / receiving files between devices according to another embodiment of the present invention.

The device file transmission / reception method according to the present embodiment can be performed by a file transmission / reception system 200 between devices included in a receiver, that is, a device that desires to receive a file among devices connected to the local network.

Referring to FIG. 5, the inter-device file transmission / reception system 200 waits for a user's input (step 510) when a transmission / reception program is executed in a receiver (step 510).

At this time, the device-to-device file transmission / reception system 200 can connect a receiver, which is connected to the local network, to a receiver by connecting a receiver on which a transmission / reception program is executed to a local network. That is, the receiver maintains the disconnection state from the local network, and can communicate with the local network only when it wants to receive the file.

When the file exchange command is generated (step 530) by the user, the file transmission / reception system 200 between the devices selects one of the transmitters associated with the file exchange command It checks if there is a transmitter with the file (step 530).

In this step 530, the device-to-device file transmission / reception system 200 can confirm to the devices (transmitters) connected to the local network whether there is a received file to be transmitted. For example, the inter-device file transmission / reception system 200 can check whether the received file is stored in the transmission file storage box in the transmitter.

If it is determined in step 530 that the received file exists in at least one of the transmitters connected to the receiver, the inter-device file transmission / reception system 200 encrypts the authentication information held in the receiver (Step 550), and transmits the encrypted authentication information to the transmitter to request the received file (step 560).

The transmitter decrypts the encrypted authentication information, determines whether the authentication information matches the authentication information about the received file, and transmits the received file to the receiver if the authentication file matches the authentication information. That is, the transmitter can determine the transmission of the received file to the receiver according to whether the authentication information is matched with each other.

The inter-device file transmission / reception system 200 receives the reception file transmitted by the transmitter (step 570).

Therefore, according to the present invention, the receiver can transmit a specific transmitter (e.g., a 'tablet PC') among transmitters connected through a local network without specifying a file exchange object (transmitter) ) Can be easily and selectively received.

FIG. 6 is a flowchart illustrating a procedure of a file transmission / reception method between devices according to another embodiment of the present invention.

The file transmission / reception method according to the present embodiment can be performed by a file transmission / reception system 200 between devices included in a device, that is, a device that wants to transmit a file among devices connected to the local network.

Referring to FIG. 6, the apparatus-to-apparatus file transmission / reception system 200 waits for a user's input (step 610) when a transmission / reception program is executed in a transmitter (step 610).

When a transmission file is selected by a user and a 'file transmission' is inputted and a file exchange command is generated (step 630), the apparatus-to-apparatus file transmission / reception system 200 transmits a link to the transmission file or the transmission file, Stores it in a storage box, and generates authentication information for the transmission file (step 640). The device-to-device file transmission / reception system 200 can encrypt authentication information such as a password input by a user or a user's face image, and store the authentication information together with the transmission file.

The inter-device file transmission / reception system 200 determines whether there is a receiver connected to the transmitter through a local network (step 650). This step 650 may be a step of waiting for a connection of the client (receiver).

That is, the device-to-device file transmission / reception system 200 can identify a receiver that generates a file exchange command regarding 'file reception' among devices connected to the local network.

As a result of the checking in step 650, if it is confirmed that the receiver desiring to receive the file is connected to the transmitter, the inter-device file transmission / reception system 200 determines whether the authentication information transmitted from the receiver matches the generated authentication information (Step 660).

When the authentication information is matched with each other, the device-to-device file transmission / reception system 200 transmits the transmission file to the connected receiver (step 670), or if the authentication information is not matched, The inter-device file transmission / reception system 200 can determine the transmission of the transmission file to the receiver according to whether the authentication information is matched with each other.

The inter-device file transmission / reception system 200 may delete the authentication information transmitted from the receiver by transmitting the transmission file to the connected receiver. In addition, according to the embodiment, the inter-device file transmission / reception system 200 can delete the transmission file temporarily stored in the transmission file storage box or the link related to the transmission file.

Therefore, according to the present invention, the transmitter can perform the matching of the authentication information to a specific receiver (e.g., a 'tablet PC') of receivers connected through a local network without specifying a separate file exchange object (receiver) , It is possible to transmit the received transmission file.
