primarily determining whether to allow the compound message to be sent based on metadata of the compound message and the permission information; and
secondarily determining whether to allow each of the plurality of child messages to be sent in response to the determination that the compound message is a message allowed to be sent.
4. The method of claim 3 , wherein the permission information comprises information about terminals allowed to send messages, the metadata of the compound message comprises terminal information of the sender, and the primarily determining of whether to allow the compound message to be sent comprises determining whether to allow the compound message to be sent by comparing the information about the terminals allowed to send messages with the terminal information of the sender.
5. The method of claim 3 , wherein the permission information comprises information about a network where message transmission is allowed, the metadata of the compound message comprises information about a network where a terminal of the sender is located, and the primarily determining of whether to allow the compound message to be sent comprises determining whether to allow the compound message to be sent by comparing the information about the network where message transmission is allowed with the information about the network where the terminal of the sender is located.
6. The method of claim 1 , wherein content of a predefined type or access information for the content is recorded in a content field of each of the plurality of child messages, type information of the content is recorded in the metadata field of each of the plurality of child messages, the permission information comprises type information of content allowed to be sent, and the determining of whether to allow each of the plurality of child messages to be sent comprises determining whether to allow each of the plurality of child messages to be sent by comparing the type information of the content with the type information of the content allowed to be sent.
7. The method of claim 6 , wherein if the content is file content, a type of the content is distinguished based on an extension of the file content.
8. The method of claim 6 , wherein a type of the content allowed to be sent varies according to a terminal of the sender.
9. The method of claim 6 , wherein a type of the content allowed to be sent varies according to a network where a terminal of the sender is located.
10. The method of claim 6 , wherein a type of the content allowed to be sent varies according to the sender's affiliation or position.
11. The method of claim 1 , wherein the permission information comprises information about keywords not allowed to be sent, and the determining of whether to allow each of the plurality of child messages to be sent comprises determining whether to allow each of the plurality of child messages to be sent based on whether the keywords not allowed to be sent are included in content of each of the plurality of child messages.
12. The method of claim 1 , wherein the controlling of the transmission comprises blocking the transmission of the compound message in response to the determination that a message not allowed to be sent exists among the plurality of child messages.
13. The method of claim 1 , wherein the controlling of the transmission comprises:
reconstructing the compound message by excluding a message not allowed to be sent or replacing the message not allowed to be sent with a notification message informing of transmission blocking in response to the determination that the message not allowed to be sent exists among the plurality of child messages; and
sending the reconstructed compound message to the receiver of the compound message.
14. The method of claim 1 , wherein the controlling of the transmission comprises:
masking a message not allowed to be sent in response to the determination that the message not allowed to be sent exists among the plurality of child messages; and
sending the compound message comprising the masked message to the receiver of the compound message.
15. A message server comprising:
one or more processors;
a memory storing one or more instructions; and
a communication interface,
wherein the one or more processors execute the stored one or more instructions to perform:
an operation of receiving a transmission request for a compound message which is a bundled message comprising a parent message and a plurality of child messages, the bundled message being generated by bundling the plurality of child messages by a sender to be sent to a receiver, wherein the parent message serves as a container for the plurality of child messages, and information of the sender and the receiver is included in a metadata field of the parent message and not included in a metadata field of each of the plurality of child messages;
an operation of obtaining permission information for the sender of the compound message using the information of the sender included in the metadata field of the parent message;
an operation of determining whether to allow each of the plurality of child messages to be sent based on the permission information; and
an operation of controlling transmission of the compound message based on the determination result,
wherein the information of the sender and the receiver included in the metadata field of the parent message is applied to each of the plurality of child messages.
16. The message server of claim 15 , wherein content of a predefined type or access information for the content is recorded in a content field of each of the plurality of child messages, type information of the content is recorded in the metadata field of each of the plurality of child messages, the permission information comprises type information of content allowed to be sent, and the operation of determining whether to allow each of the plurality of child messages to be sent comprises an operation of determining whether to allow each of the plurality of child messages to be sent by comparing the type information of the content with the type information of the content allowed to be sent.
17. The message server of claim 15 , wherein the permission information comprises information about keywords not allowed to be sent, and the operation of determining whether to allow each of the plurality of child messages to be sent comprises an operation of determining whether to allow each of the plurality of child messages to be sent based on whether the keywords not allowed to be sent are included in content of each of the plurality of child messages.
18. The message server of claim 15 , wherein the operation of controlling the transmission comprises:
an operation of reconstructing the compound message by excluding a message not allowed to be sent or replacing the message not allowed to be sent with a notification message informing of transmission blocking in response to the determination that the message not allowed to be sent exists among the plurality of child messages; and
an operation of sending the reconstructed compound message to the receiver of the compound message.
19. The message server of claim 15 , wherein the operation of controlling the transmission comprises:
an operation of masking a message not allowed to be sent in response to the determination that the message not allowed to be sent exists among the plurality of child messages; and
an operation of sending the compound message comprising the masked message to the receiver of the compound message.
