Description
The present invention relates to a device-to-device file transmission / reception system for supporting a free file transmission / reception between different devices possessed by an individual by transmitting / receiving files between devices without performing a pre-registration procedure through real-time authentication.
In recent years, with the continuous development of various devices such as smart phones, tablet PCs, wearable devices, and the like, the types and number of devices used by individuals gradually increase, so that users can select files A technique for easily transmitting and receiving data is proposed.
Conventionally proposed file transmission / reception between devices can largely be divided into a method of downloading and using a file held in an external cloud server from the device, and a method of exchanging files between devices registered with each other and connected to the network.
However, in the case of using an external cloud server, it is necessary to have an account for accessing an external cloud server, and it may have a disadvantage that all devices must be logged in with the same account.
Further, in the case of a method of exchanging files between the devices registered with each other, since the devices must be registered with each other before the files are sent and received, there is an inconvenience that the device must be registered again every time a file is transmitted / It is possible to send and receive files only to the devices that are connected to the network.
Accordingly, there is a demand for a technology that enables free file transmission / reception between devices without a pre-registration procedure.
The embodiment of the present invention transmits a file exchange command to each of the first transmitters having a received file among the transmitters connected to the receiver where the file exchange command is generated, And receiving the received file from the second transmitter that responds to the device designation command, thereby supporting free file transmission / reception between the different devices of the individual without pre-registration procedure .
Also, the embodiment of the present invention may be configured to maintain the authentication information for the second transmitter that has transmitted the device designation command, and if authentication information received from the second transmitter together with the received file does not match the held, And stores the received file in a received file archive so that files can be exchanged between devices connected to the local network through real-time authentication without a pre-registration procedure.
It is another object of the present invention to easily receive a reception file of a specific transmitter among transmitters connected to a receiver through real-time authentication without specifying a file exchange object (transmitter) by a user of the receiver .
The device-to-device file transmission / reception system according to an embodiment of the present invention includes an identification unit for identifying a first transmitter having a reception file associated with the file exchange command among a transmitter connected to a receiver for generating a file exchange command, A transmission unit for transmitting a file exchange command to each of the first transmitters and for transmitting a device designation command to any one of the first transmitters when the file exchange command is associated with an independent reception, And a receiving unit that receives the received file from a second transmitting transmitter.
Also, a method of transmitting / receiving files between devices according to an embodiment of the present invention includes: identifying a first transmitter having a reception file associated with the file exchange command among a transmitter connected to a receiver where a file exchange command is generated; Transmitting a file exchange command to each of the first transmitters and, if the file exchange command is associated with an exclusive receipt, further transmitting a device designation command to any one of the first transmitters; And receiving the received file from a responding second transmitter.
According to an embodiment of the present invention, when 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, The first device transmits the device designation command to any one of the first transmitters and receives the received file from the second sender that responds to the device designation command so that a free file transmission / .
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.
