    Abstract: A server includes a session management device establishing a video call session between a first electronic apparatus of a first user and a second electronic apparatus of a second user, a communication device receiving match satisfaction calculated from the first electronic apparatus through the video call session, an image analysis device obtaining first feature point distribution information from a face image of the first user and obtaining second feature point distribution information from a face image of the second user, a processor training a machine learning model by using the first feature point distribution information, the second feature point distribution information, and the match satisfaction and estimating the match satisfaction of the first user for each of standby users by using the trained machine learning model when a video call connection between the first electronic apparatus and the second electronic apparatus is terminated, and a user management device selecting a third user, who becomes a next video call counterpart of the first user, from among the standby users by using the estimated match satisfaction.

    Abstract: A computer program is stored in a computer-readable recording medium to implement a test group distribution method in a server device. The test group distribution method includes: generating identification information of a first test to be performed, differently from identification information of at least one test that is registered in advance, wherein the first test is performed by a plurality of user terminals classified into a plurality of groups; generating a unique identifier of each of users by using a first key comprising identification information of each user and a second key comprising the identification information of the first test; and determining test group information of each user based on the unique identifier of each user, the test group information corresponding to a group to which each user belongs.
