Preventing and Investigating Criminal Offences

Indoor positioning technology can help prevent and investigate crimes and vandalism.


At a glance
  • storage of smartphone IDs
  • correlation with commited crimes



Problem definition

The police and the damaged party would like to prevent and investigate crimes and vandalism.

Here are some examples:
  • A company site has been burgled. The management wants to prevent further burglary and wants to inform the police in time so that they can identify the thieves.
  • In some branches of a bank cash machines are regularly emptied or stolen. The bank wishes to find out when thieves are near a branch so that an alarm can be given.
  • A transportation company wants to prevent and investigate vandalism.


Solution

These application examples include two aims:

Prevention: infsoft’s solution records smartphones which have been near the crime scene when the crime was committed. It will give an alarm when the same smartphone appears at a new possible crime scene. In this way it is possible to catch the perpetrator when he is about to prepare another crime.

Investigation: The system observes a specific area and records all smartphones nearby. If a crime happens, the data can help identifying the perpetrator.

Technical implementation

Preventing and Investigating Criminal Offences
infsoft Locator Nodes are installed in the area which should be observed. They record the unique IDs which every smartphone emits. The IDs which have been near the crime scene when the crime happened, can be recorded and recognized. It is not possible to identify individuals according to their ID. But through a procedure of exclusion the number of suspects can be limited. It is also possible to match these data with camera images. The IDs of authorized persons (i.e. security staff) can be excluded by saving them on a white list.

Attention should be paid to the restrictions regarding Wi-Fi tracking, which means that it is not always possible to unambiguously determine devices in an area.
