Fujitsu Labs invented a method for searching encrypted data
The method developed by Fujitsu Labs allows you to search 16,000 characters per second encrypted data. It could be used to perform sequential DNA analysis.
As if spying on a large scale the U.S. National Security Agency (NSA) was not sufficient to generate enough concern for the protection of privacy, now Fujitsu laboratories that they had put developed a rapid incognito to perform searches in encrypted data method. The technology uses a homomorphic encryption mode said, which allows you to process encrypted data without having to decrypt. The research method developed by Fujitsu can handle lots of data at the speed of 16,000 characters per second. Above all, the search can be any sequence of characters without the support of key words as in one of the labs of Alcatel Lucent.
Japanese Labs intends to market its technology in 2015 and sell it as an analytical tool. Fujitsu have no doubt that it will find use in a world where there is more data to process. But if one believes Labs researchers, this technology can protect privacy. “Our technology is based on public key encryption,” said Jun Kogure, director of research at the Laboratory of Social Innovation in the Secure Computing Lab Fujitsu Laboratories. “When you generate a public key, it also gets a secret key paired with the public key. To the analysis itself, we only need the public key that everyone can get. But insofar as the search results are encrypted, only those who have the secret key can see the results.”
A method adapted to search DNA sequencing
Data thieves or spies who try to use the method would therefore their costs, according to researchers at the Labs. “They can still search, but without the secret key, they cannot use their results” confirmed the research director of the Laboratory for Social Innovation. Method Fujitsu is also distinguished by the fact that it is not based on keywords previously recorded. In this, it changes the usual approach reserved for analysis of encrypted data. “Most existing methods use research methods based on tags with keywords and pre ” tags ” that can determine whether, in the research phase, the specified private key corresponds to one word tags recorded, “said Jun Kogure. “Our technology is not based on research by tag. Our method of homomorphic encryption, we can do full-text searches.”
Batch search is performed using strings encrypted, and the search results themselves are encrypted. This means that only users who have the decryption key can read them. Among the possible applications, the sequential search Labs mentions the filaments on DNA. The method would preserve the confidentiality of the information in DNA while delivering a useful result. It could be applied in many types of DNA research. Fujitsu technology could also be used to do research in educational outcomes encrypted from various institutions for statistical purposes, for example.
