Subject Re: data security
Date Thu, 10 Apr 2014 06:01:46 GMT
There are quite a few projects that are looking into this.  I myself am part of a TSB (part
government funded research) project involving securing data in the cloud.  Generally the
data is secured in a layer on top of hadoop rather than specifically as part of hadoop itself. 


Our solution essentially involves encrypting data within the HDFS and providing mechanisms
for hadoop to decrypt, use, then re-encrypt the results.  It also provides mechanisms for
secure deletion of data when it's not required anymore (that's actually a minor patch within
HDFS, rather than on top if it though)




Contact me if you need more information, we are about to start trials in the next few months.
