The last weeks I am blogging, writing articles and social networking about homomorphic encryption.
This all started when reading the news Fujitsu Labs Ltd. wants to implement a DNA read- and processtechnology using homomorphic encryption where encrypted genetic data can be read without decrypting it.
Great news for a software tester with a bioinformatics background and privacy at heart!
Fujitsu Labs claims it can ensure privacy by encrypting the query , the data and the searchresults, so a possible third party (read pharmaceutical company etc.) can't see to which person the DNA data belongs to.
But, homomorphic encryption is a slow process, how does Fujitsu cope with this?
They have 2 solutions:
The first is that the searches are in batchmode (16K per second) and second is that the search already starts when encrypting the data.
Cool stuff, but still questions pop up in my mind: is the encryption undecryptable for hackers, is the performance really 16K strings per second (performance tes(t!)), are the search results correct and can the data be tampered with with for instance Man in the Middle Attacks?
Questions I like to see answered and I wait until more news emerges.
Implementation is set in 2015. Let's see what happens and how the competition will deal with this.
