Description

Data transfer method {DATA TRANSMISSION METHOD}

The present invention relates to a data transmission method, and more particularly to a data transmission method for transmitting data such as a message on the Internet.

Computer systems such as laptops and desktop computers, and smart terminals such as smartphones and tablet PCs, are now becoming almost essential in real life. Such a computer system and a smart terminal may perform various functions according to an installed program, a representative example of which is to transmit data, for example, a message or a file, to another terminal.

First, a representative method of transmitting a message may be a method through a mail program or a messenger program. For example, after executing a messenger program installed in a computer system or a smartphone, a user may create a message to be transmitted, select at least one party to be transmitted, and transmit the message to the selected party.

In addition, a representative method of transferring a file may be a method through a file transfer program such as P2P. For example, after executing a file transfer program installed in a computer system or a smartphone, a user may select a file to be transmitted and at least one counterpart to transmit, and transmit the selected file to the selected counterpart.

In this way, the other party receiving the message or file may receive the message or file at any time after receiving the message or file, and may copy and re-transmit it to another person as needed. That is, the other party has the right to dispose or use the received message or file.

On the other hand, the message or file to be transmitted may need to be read only to the other party receiving the security or only a certain time. However, if the receiving party has the right to dispose or use the message or file, the message or file cannot be viewed only by the other party or only for a certain time.

In addition, the message or file to be transmitted may be leaked to the malicious user while being transmitted to the counterpart. At this time, the malicious user may also have the right to dispose or use the message or file. As such, the message or file may be used outside the intent of the user to send the message or file.

Accordingly, an object of the present invention is to provide a data transmission method capable of limiting the use of data to be transmitted.

A conceptual diagram illustrating an example applied to a network based on blockchain technology.

1 to 4, in the data transmission method according to the present embodiment, first of all, the terminal 10 of user A may determine data to transmit (hereinafter, referred to as “target data”) (S100). Specifically, for example, the terminal 10 of the user A may select at least one of a plurality of data pre-stored in the internal memory to determine the target data. Alternatively, the user A's terminal 10 may generate arbitrary data by the user's input action through various types of input devices and determine the target data.

In the present embodiment, the target data may include at least one of a message and a file. For example, the target data may be a text message, a video file, a music file, an image file, a document file, or the like.

On the other hand, before the step S100, the user terminal 10 of the user A is installed after the data transmission program for performing the transmission of the target data or executed, or connected to the server providing the data transmission service to transmit the data You can run the program.

Subsequently, the terminal 10 of the user A may determine at least one user (hereinafter, referred to as a “target user”) to transmit the target data (S200). For example, the terminal 10 of the user A may select at least one user from among a plurality of users and determine the target user.

In this embodiment, each of the terminal 10 of the user A and the terminals of the users are each a smart terminal such as a smartphone, a tablet PC, or the like, as shown in FIG. 2, or a laptop, a tablet PC, or the like, as shown in FIG. It may be a computer system. In addition, the terminal A of the user A and the terminals of the users may be nodes of a network formed based on BlockChain technology.

Meanwhile, although the step S200 is shown as being performed after the step S100 in FIG. 1, it may alternatively be performed before the step S100 or at the same time as the step S100. For example, the user A's terminal 10 may first determine the target user and later determine the target data.

5 is a flowchart illustrating a process of generating a condition execution statement in the data transmission method of FIG. 1.

1 and 5, the terminal 10 of the user A may generate a condition execution statement for determining the use of the target data (S300). Here, although the step S300 is shown as being performed after the step S200 in FIG. 1, alternatively, the step S100 may be performed before or simultaneously with the step S100, or may be performed between the step S100 and the step S200, and the step S200. And may be performed simultaneously. For example, the terminal 10 of the user A may first generate the condition execution statement, and then determine the target data and the target user later.

Referring to step (S300) of generating the condition execution statement in detail, after the user terminal 10 of the user A generates condition execution information for generating the condition execution statement (S310), the condition execution information is read. In operation S320, the terminal may be transmitted to the terminal of the target user. Subsequently, after the terminal of the target user receives and confirms the condition execution information, if the user agrees to the condition execution information, the terminal generates a confirmation signal indicating that the condition execution information is agreed to the user 10's terminal 10. When receiving the confirmation signal (S330), the user A terminal 10 may generate the condition execution statement in response to the confirmation signal (S340).

In the present embodiment, when the terminal 10 of the user A and the terminal of the target user are nodes of a network formed based on BlockChain technology, the condition execution statement is a smart signed between the nodes. It may be a smart contract. That is, the user A's terminal 10 may limit the use of the target data by concluding the smart contract with the terminal of the target user before transmitting the target data.

6 is a view for explaining an example of the condition execution statement of FIG. 5, and FIG. 7 is a view for explaining another example of the condition execution statement of FIG. 5.

6 and 7, when the execution condition is satisfied, the condition execution statement generated in step S300 may be a statement that automatically executes an execution command on the target data. For example, the condition execution statement may be a statement composed of 'IF {execution condition} THEN {execution command}'.

In one embodiment, the execution condition may be a condition for performing a prohibition on the target data. That is, when the prohibition is performed in the terminal of the target user, the execution command may be automatically performed on the target data. The prohibition may include storing the target data in a memory, transmitting the target data to a terminal of another user, screenshotting a screen on which the target data is displayed, printing the target data, or It may include at least one of actions to edit the target data.

As another example, the execution condition may be a condition in which the current time exceeds a setting period. That is, when the current time point exceeds the set period, the execution command may be automatically performed on the target data.

In the present embodiment, the execution condition is a condition for performing a prohibition act on the target data, or when the current time is a condition exceeding a set period, the execution command deletes the target data and the target data. It may include at least one of the prohibition of reading order to prohibit the reading of. In this case, unless the prohibition is performed or the setting period is elapsed and the target data is deleted or the reading is prohibited, the target user performs an operation of viewing, copying, printing, editing, or transmitting the target data. can do.

As another example, the execution condition may be a condition that the target user is included in the execution permission target. That is, when the target user is included in the execution permission target, the execution command may be automatically executed on the target data, but when the target user is not included in the execution permission target, The execution command cannot be executed.

As another example, the execution condition may be a condition that a current time point is within an execution permission period. That is, if the current time point is within the execution permission period, the execution command may be automatically executed on the target data, but if the current time point is not within the execution permission period, the execution command is performed on the target data. Can't.

In the present embodiment, the execution condition is a condition that the target user is included in the execution permission target, or when the current time is a condition within the execution permission period, the execution command is a read permission command for allowing the reading of the target data, At least one of a transmission permission command for allowing the transmission of the target data to a terminal of another user, and a print permission command for allowing the printing of the target data. Therefore, when the target user is not included in the execution permission target or the current time is not within the execution permission period, the target user cannot perform any action on the target data.

8 is a flowchart illustrating a process of transmitting target data in the data transmission method of FIG. 1.

1 and 8, the terminal 10 of the user A may transmit the target data combined with the condition execution statement to the terminal of the target user (S400).

In the present embodiment, when the terminal 10 of the user A and the terminal of the target user are nodes of a network formed based on BlockChain technology, the target data is transmitted to the terminal of the target user. In step S400, the terminal 10 of the user A combines the condition execution statement with the target data (S410), and generates a block including the target data to which the condition execution statement is combined (S420). In operation S430, the block may be transmitted to the terminal of the target user. As a result, the block may be stored in the terminal 10 of the user A and the terminal of the target user, respectively, and may be connected to a previously stored block and a previous block to form a block chain.

Meanwhile, the block may include other information, personal information, situation information, transaction degree, etc. in addition to the target data. For example, the block may include a data area including the target data and an encryption area including a hash value of a previous block and a hash value of a current block.

As described above, according to the present embodiment, as the terminal 10 of the user A combines the condition execution statement with the target data to be transmitted to the terminal of the target user, the terminal of the target user executes the condition. The use of the target data may be restricted according to the statement. That is, since the terminal of the target user may execute the execution command on the target data when the execution condition is satisfied, the use of the target data may be restricted. Thus, it is possible to block and prevent the target data from being used outside the intention of the user.

In the detailed description of the present invention described above with reference to the preferred embodiments of the present invention, those skilled in the art or those skilled in the art having ordinary skill in the art will be described in the claims to be described later It will be understood that various modifications and variations can be made in the present invention without departing from the scope of the present invention.
