Smartphones have become a crucial part of every criminal investigation and an important scientific investigation tool. Criminal cases often involve analysis of another person’s phone, but, of course, there are also several challenges that come with it, such as converting images to text and recovering data without damaging the integrity of the phone.
In one recent case, the investigators extracted data from hospital staff that revealed an interesting fact; the doctor was not present during childbirth, which was overseen by insufficiently-qualified nurses instead.
5G will be another notable catalyst allowing for an explosion in digital evidence. Smart home devices are already saving data that can be used as evidence – pet monitoring and home security solutions are all great examples of this. Of course, there are others: self-driving cars, drones, CCTVs, and DVRs are all IoT devices that fit the bill.
Videos, for example, are of higher and higher quality, which should allow investigators to do a better job. While autonomous vehicles store driving history and navigation data, all of which will pave the way to solving numerous crimes.
With all these 5G and IoT opportunities, there comes a new challenge: how will we be able to analyse the huge amount of accumulated data? Big data analytics could be an answer. For video analysis, keyword searching technology has the potential to solve at least one part of the challenge. This will allow the investigators to input a simple keyword, and the program will search the video footage for hits such as license plate numbers and faces.
