EconoTimes recently reported that the US is planning to apply blockchain technology to address the issue of illegal migrants and criminal behaviour at the borders with Mexico and Canada. First of all, this is about using a blockchain to store and protect the data collected by CCTV cameras. At the moment, all video recordings are stored in centralized databases, which is extremely inefficient and unsafe. Firstly, they are vulnerable to cyber-attacks. Secondly, even the best staff are not capable of monitoring such a large number of video recordings. This means they cannot respond to illegal actions in a timely manner. Thirdly, a fairly large budget is required to store this amount of data.
