It is recorded that the Chinese Ministry of Public Security has developed a blockchain system to store the evidence that police gathered from the scene in a safer way.
According to a statement by the Chinese Intellectual Property Office, the ministry’s research arm applied for a patent application in November 2017. The subject of this application deals with a blockchain-based system that timestamps and stores data in the cloud system to develop a more transparent and unmiscible storage procedure.
While centralized cloud platforms are gaining popularity for sharing data, the Ministry, which is above all the police forces in China, said that the evidence sent to this current cloud storage system can easily be changed because of the system’s structure.
In addition, the lack of a necessary technology to control this cloud storage process can make this process less reliable.
For this reason, this patented blockchain system will first request that cloud providers send deposition data, and after receiving multiple signatures of approval from both sides, it will save it and stamp it on the blockchain with the date stamp. This will help the system to create an unalterable copy of the transaction, as well as the print of the person who made the transaction and keep track of the transaction time and the date.
The mentioned patent application is not a very original description, as it is generally considered to reflect the basic mechanism of the standard blockchains. However, it is still an important step made by someone from China’s State Council cabinet-level ministries.
What’s more, the Chinese Ministry of Public Security is not the only Chinese institution that wants to take advantage of blockchain technologies.
The National Audit Office of China, which is another cabinet-level institution, is among those who are considering taking advantage of the blockchain technology to store data.
