Abstract: Disclosed are a method and system for providing social media using a partition function. A method of providing social media may include receiving sharing information input in one or more user terminals included in a chat room, assigning partitioned pieces generated by partitioning the received sharing information based on the number of users included in the chat room to user terminals included in the chat room, receiving a request for the reading of specific-processed sharing information from a specific user terminal included in the chat room, restoring the specific-processed sharing information based on the partitioned pieces received from the user terminals included in the chat room, and transmitting the restored sharing information to the user terminal that has requested the reading of the sharing information.
