The Fujitsu Laboratories, research center of Fujitsu, and the Fujitsu Laboratories of America announces the development of security technologies blockchain to protect sensitive data between multiple organizations. The solutions should be marketed still this year.
To enhance and apply the blockchain in various segments of the market, Fujitsu has developed two technologies: the first is a technology restriction transactions based on pre-defined policy to restrict the negotiations, as well as users. The second technology is the encryption of documents which allows the use of only the relevant parts — that hold multiple keys distributed to secure access to the information recorded in the blockchain.
The characteristic most relevant to the blockchain is to provide the sharing of information with high transparency and reliability, without management by a specific organization. However, in applications of the trading financial, for example, there are operational issues related to the safe execution of business, such as key management. In addition, the application of management documents that preserve the original state of the materials lead to some problems in the creation of a system, which could limit what people would be allowed to make reference to the recorded information in the blockchain.
With the new technology of restriction of transactions, the operations that prevent the misuse or abuse of keys will become possible, allowing the safe use of the blockchain, says the company. Already with the technology of encryption of documents, it is possible to create a workflow in which the documents are recognized by the collective decision-making or between organizations as specified, or, in situations where the documents can be restored when the keys are lost.
from these new security technologies, Fujitsu says that you can contribute with the expansion of applicable fields where blockchain can be used, which includes several areas, such as finance, logistics, supply chain and management of official documents. Fujitsu Laboratories is conducting tests on the applicability of the blockchain with the goal of commercializing the technologies from the fiscal year 2017.
