In the current information technology era, social media users increase every year. Recorded in 2017, among 143.26 million internet users, 87.13% or about 124.82 million used social media as part of lifestyle. There are some crimes such as robberies and murder happen caused by posting pictures or video regarding the privacy of Instagram users. In this research, there are some actions that users can do to avoid the crimes. This research aims to measure the privacy awareness of Instagram users in Indonesia by doing measurement using three dimensions of awareness such as Attitude, Knowledge, Behavior with four focus areas of privacy, namely Perceived Surveillance, Perceived Intrusion, Secondary Use of Information, Disclosing Personal Information. This research used the Analytical Hierarchy Process (AHP) method to measure the privacy awareness of Instagram users in Indonesia. Privacy awareness level in all dimensions is good. However, the attitude dimension with focus areas on perceived surveillance and perceived intrusion is still in the criterion of average awareness. It means that those focus areas potentially need treatment to improve such as being more careful while posting some content on Instagram because unauthorized people can get access more easily to the user's personal information and the users' activities.
