Blockchain has gradually become a potential solution for security agencies

nWalkout commentary: With the increasing influence of blockchain technology, people’s understanding of the technology is also gradually profound, many government agencies began to consider more of its positive role. For example, many security agencies have gradually begun their exploration of the blockchain in hopes of using it to solve some long-standing problems rather than simply linking them to criminals’ behavior. Although the technology in the security sector still needs time to deploy, this trend will benefit the overall development of the technology.n

Previously, the interest of the police and security agencies in blockchain technology was limited to criminals tracking the transfer of illegal funds from banks.n
However, the situation is changing and some police, military and civilian agencies have seen the blockchain as a potential solution to the problems that they have been dealing with over the years, namely, how to protect the data and at the same time, Let the owners stay in control sharing.n
For example, Australia recently hired Houston Kemp, a Singapore consulting firm, to create a blockchain-based system to record the intelligence given by investigators and others and improve the way in which important information can be shared.n
Adrian Kemp, who founded Houston Kemp, said: “They have been trying to establish a centralized platform for many years, but people are reluctant to share information.” AUSTRAC, the Australian financial intelligence agency and criminal intelligence commission, also donated $ 1 million ($ 757,500) to Houston Kemp ) Of funds.n
The attractiveness of blockchain for data sharing includes three aspects.n
Its books or databases are not under the control of any one party, scattered across multiple computers and harder to spoil. Once the information is entered, it can not be altered or tampered with. And by using so-called smart contracts, the information owner can easily set who has access to what.n
This shows how far blockchain technology has evolved over the decade since Mr. Nakamoto’s White Paper on bitcoin and blockchain ledger features has been published.n
Bitcoin is both the currency of choice for liberals and speculators, and is also favored by unscrupulous hackers. Bitcoin prices fluctuated sharply and hit a record high at the end of last month.n
Governments have been exploring ways to store some data, such as land records, contracts and assets, in the blockchain, and the financial industry has also tried to streamline transactions and back-office systems with blockchain, albeit with limited success.n

Most law enforcement agencies that come into contact with the blockchain are working with start-ups to look for evidence of criminal transactions by analyzing it.n
But that attitude has changed over the past year or so.n
The U.S. Air Force (USAF) has funded research projects to explore how blockchain can ensure data is not changed. In May this year, the Defense Advanced Research Projects Agency (DARPA) also allocated funds to a company that is engaged in an encrypted chat project to develop secure messaging services based on the blockchain.n
A recent amendment to the U.S. Senate’s defense bill requires the government to report on “potential attacks and defensive network applications for blockchain and other distributed database technologies,” and the use of these technologies by foreign governments, extremists and criminals.n
According to some consultants and companies working for the British government department, Britain is also exploring several uses of the blockchain.n
Cambridge Consultants, the UK consultancy, said it has partnered with the Defense Science and Technology Laboratory at the Department of Defense (MoD) to leverage blockchain to increase the credibility of the network of sensors such as surveillance cameras.n
A blog post on the website of the Justice Department said the department is considering putting all the evidence (video, email and documents) on the blockchain to prove they have not been altered.n
Marcus Ralphs was a soldier in the past and is now CEO of ByzGen. The company develops blockchain for the security sector. Ralphs said his company is working with the Department of Defense to leverage the blockchain to track the status and level of individual security clearances. Other tasks include helping the Ministry of Foreign Affairs improve the way in which work permits are issued and recorded.n

These are still only in the early stages.n
Kemp said no one can guarantee his project can be more widely deployed. Some of those who work with AUSTRAC are skeptical of these projects as having a greater role in the private sector because of their own lack of resources and creativity.n
Private-equity detective Simon Smith is involved in AUSTRAC’s case, he said. “The government just wants to push responsibility to the private sector.”n
Many police and military forces are unprepared for the necessary technical and intellectual leaps.n
“The Police Foundation,” a think tank specializing in law and order and crime in Britain, is pushing the British police to explore the blockchain, but its director, Rick Muir, said “we are still at a stage of exploring what the blockchain is.”n
Last year, Neil Barnas, a major US Air Force major, wrote an essay on the potential of the blockchain in defense. He said the U.S. military and security agencies are slowly recognizing this.n
The problem, he said, is that people in the military are more likely to be centralized rather than decentralized systems supported by blockchain distributed ledgers.n
However, according to ByzGen’s Ralphs, the link between technology and crime does not diminish its positive appeal to those who see the potential of the blockchain.n
He said: “Negative comments about this technology did not reduce our partner’s interest in it.”n
