The Chinese police considers possibility of the blockchain technology for security of evidence, the data of investigations and examinations.
The Ministry of Public Security of PR China developed the blockchain system for reliable keeping of evidence and proofs collected in the process of police investigations. According to the data published by IPO (Intellectual Property Office) of China, in November, 2017 the research department of the Ministry applied for a patent for creating blockchain-based system which will help to keep and store necessary data. It will provide more transparent and abuse-free investigation.
The centralized cloud platforms become more and more popular ways of data exchange. The problem with existing examination procedure is the following: the data sent through cloud providers can be easily changed, as the Ministry declare. Besides, the absence of effective technology of clear control of cloud storage process can lead to some problems, for example, the lack of reliability of data. Thus, the blockchain system will request data about evidence which will be recorded to the blocks which are impossible to falsify.
