    How Big data help to fight crime

    Police and Law enforcement agency has changed dynamically by technology over the few years starting from the use of CCTV cameras, Thumbprint(fingerprint), DNA and ballistic analysis, However, big data has an impact on the Law enforcement agency than any other technology development.

    Big data has been used to predict crime mapping. Subsequently, the dataset has been drafted with the following as header to enhance optimism input of data:

    • Crime type
    • Date
    • Time
    • Crime locations

    Law enforcement agency uses this dataset pattern to collect data from crime scenes and use it to predict :

    • The crime occurred on High Street
    • The crime occurred at around the same time as his previous convictions
    • Similar crime
    • Actual Criminals and bandits.

    For instance:

    If John Doe is convicted of rape, and all of his rapes occurred on High Street, algorithms may be able to suggest John Doe as a rapist if:

    • Rapes occurred on High Street
    • Rapes occurred at around the same time as his previous convictions
    • Similar women were raped.

    Of course, it may not be John Doe, but this form of predictive modeling is an option with big data. It may be possible to scour records, looking for similar crimes with similar circumstances and tying them together.

    The accuracy of such systems, such as the Harm Assessment Risk Tool, has shown to be highly accurate for low-risk individuals with a 98% accuracy rate. High-risk accuracy rates were 88% accurate.

    As information among departments becomes more available, it may be possible for police to monitor crimes across counties, predicting where a serial criminal may strike again.
