Technology:
NTT developed a
technology to analyze encrypted data as they are. Because it allows information
processing without returning them to unencrypted original data, it reduces the
leakage risk of personal information and corporate confidential information. Because
Japan
is scheduled to enforce the ‘my number system’ that numbers people in January
2016, it is an urgent need to establish a system to prevent it from being
abused. What NTT developed is a secret calculation technology. The new
technology can rearrange data by item and figure out the average of specific
data without cracking their codes. It can rearrange data of 100,000 people in
1.5 seconds, the world’s fastest time at present.
Companies and
municipalities are susceptible for leakage of confidential information when
they get encrypted data back to unencrypted original data for analysis. To cope
with the so-called cyberterrorism, NTT’s new technology reckons that the secret
calculation technology is of great help. It also plans to utilize the new
technology for effective search of the effect of treatment approaches and efficacy
of pharmaceuticals without specifying an individual from the vast amounts of
data owned by multiple medical institutions.
