Implementation of Sex Crime Prevention Systems Using the Indoor Location Tracking System

According to the Korean National Police Agency statistics, Major Crime continues to increase, and the increase in sex violence is the highest. Studies are underway to prevent sex crimes by analyzing data related to sex crimes and sex offenders. To prevent sex crimes, the government publishes sex offenders' information onto websites and operates monitoring systems to track positions by sex offenders. However, it is difficult to track indoor positioning because the existing sex offender positioning system uses GPS. Therefore, this research suggests the location of indoor and outdoor positioning systems tracking the location of sex offenders based on Beacon. The systems proposed in this thesis provide safety information about the user's current location based on statistics from the public data portal and real-time location information of sex offenders. In order to calculate the general-specific gender-critical threat, the proposed system analyzes the date, time, and geographic information of sex crimes. If a sex offender wearing an electronic ankle tag goes indoors, an electronic ankle monitor recognizes the nearby Beacon signal and recognizes the interior location. A warning message is sent to user's mobile device if a sex offender with an electronic ankle tag is near a user who installed an application. Through the Sexual Crime Prevention System proposed in this thesis, users can identify risks in advance, and the government can reinforce the area of jurisdiction to prevent sex crimes from occurring.
