Homeland Security to Use Blockchain in Tracking Goods & People Globally
January 15, 2017
As reported by Cointelegraph, the U.S. Department of Homeland Security (DHS) has begun steps for the implementation of Blockchain technology into their IT infrastructure. DHS expects this technology to better secure data collected by security cameras, sensors, and internal databases by preventing the manipulation of data gathered by devices, such as those located at U.S. air, land, and sea ports.
Blockchain technology, while developed as the transactional system used by the cryptocurrency Bitcoin, is becoming recognized as a security solution for all kinds of transactional data, such as the exchange of biometric data between the capture and matching processes.
Blockchain technology offers more security because it recreates and distributes a database across multiple computer servers and requires any change, or data transaction, to be recorded and approved simultaneously across dispersed systems. Blockchain also makes use of hashing algorithms, which make data unreadable to humans while simultaneously retaining their ability to verify data ownership. These measures provide more security than centralized IT systems, which are more susceptible to hacking and manipulation because all data is retained in one location.
In mid-2016, Factom, a blockchain startup company, received a grant from the DHS to produce an IT blockchain security solution.
