When two or more advertisements selected according to different selection methods are displayed on the lock screen, the point manager 150 may provide points according to different levels or probabilities according to the selected criterion of two or more advertisements. For example, for an advertisement selected based on a keyword extracted from a string input through a text input means, the point may be awarded at a higher level or higher probability than for an advertisement selected in a different manner. For example, when a plurality of advertisements are provided to a user, some advertisements are selected based on keywords extracted from a character string input through a text input means, and the remaining advertisements are selected based on user's personal information, A higher level or probability point for the ad can be provided as a reward. Accordingly, it is possible to induce the user to use the memo or search function using the text input means. In addition, by promoting the use of the memo or the search function, it is possible to cumulatively record keywords received from the user, thereby collecting more information about the user's propensity or interest. The collected information can then be used again to determine the advertisement to be presented to the user, thereby enabling more sophisticated targeting.

Meanwhile, the point management unit 150 can manage points for the user. At this time, the point managed by the point management unit 150 is a point associated with the advertisement as described above, and the advertisement may be displayed on the electronic terminal to include a point acquired by the user.
