The rate of fire in buildings is gradually increasing in these days and the damage of property are severely increasing. This study suggests a methodology that provides information of the emergency exits based on indoor location services. The methodology uses determination technology and the latest update of indoor map generation via the built-in sensors of smartphone. This paper enhances the accuracy of indoor localization, and also it is to study how to provide exact indoor layout for rescuing the workers in emergency, such as fires and natural disasters.

This study has considered on basis of constitutionality that the attachment order of electronic device for tracking location doesn't violate the principle of prohibition against double jeopardy, over-prohibition, and rights to equality. The attachment order of electronic device for tracking location doesn't violate the principle of prohibition against double jeopardy because it is a security measure to restrict freedom without imprisonment. However double assessment of second conviction dangerousness at additional punishment to repeated offense and sentence of the attachment order of electronic device for tracking location could be raised objection of double jeopardy. A sex offence has a character that second conviction dangerousness and crime victimization are serious. Thus to release sex offenders is very dangerous, and protection of victims and social defence are necessary. Therefore the attachment order of electronic device for tracking location doesn't violate the principle of over-prohibition because there is a balance between human rights violation and public interest. The attachment order of electronic device for tracking location is applied special offences, but it doesn't violate the principle of rights to equality because of a sanction to character of sex offenders.
