2013 was no good year in the aspect of privacy. Intelligence services worldwide were exposed by documents indicating their spying activiities and hacking is still an important topic.
Fujitsu Labs in Japan developed an approach to cope with this problem.
Some of you may now think that this can’t be new. We live in 2014 and still don’t have ways to search encrypted? According to Fujitsu previous methods are not reliable:
There are already a number of methods for searching data in an encrypted state, but these rely on pre-registering searchable keywords, and do not allow for freeform searching. These searches face certain implementation problems as well. As search results are unencrypted, this creates the potential for unwanted disclosure on the search engine. In addition, the search process is time-consuming.
Fujitsu’s new design, however, allows freeform search while the process itself is completely encrypted and the search results are transported encrypted, too.
