[Pasig-discuss] Long-Term Preservation and Encryption / POTSHARDS

Wed Apr 22 14:10:35 EDT 2015

Object Storage is an up and coming means to store data in a non-intuitive format (i.e., massive numbers of equations), but I don't believe it inherently will meet the requirements that "encryption" provides today. Another product (Amplidata's AmpliStor) does provide the means to encrypt data within the controller before converting it to erasure codes, so that might be an effective way to handle sensitive information. But all technologies that "change" data have the built in risk of losing track of how to "unchange" the data later.

I would recommend that you look into Cleversafe. It is highly secure and the technology is designed such that the costs benefits increase as the amount of data you are storing increases.

Their client’s include some of the largest companies and government institutions in the world who have extremely sensitive data.

Hi Arvind, 

actually, I have no idea how anonymization could be done in my case. It's a few hundred terabytes, and it's company data. E-mails and that stuff. I'm afraid I'm not around in the anonymization league for now.

Hi Thorsten, 

Have you looked at data anonymization as an alternative to encryption in some scenarios, I have used it in small scale on projects and it seems to work for smaller and simple datasets but would like to hear more about this technique from tools and research perspective. 

Thanks

Dear Archivers, 

I'm investigating in options to secure sensitive content in the public cloud. I'm looking for a good paper that shows all the issues when encrypting data for the long term. (Encryption algorythm weakening, migration, key loss, key management and migration, etc). I found some stuff with Google, but if someone has something really convincing, I appreciate a link. 

Second, I found POTSHARDS as a really interesting option.

It's some years ago, and I haven't found if it got picked up somewhere and developed any further. 
Did anyone deal with this solution, know of someone who does, or follows a similar approach? 

Contact to the fellows from UC Santa Cruz? 
That would be an interesting topic for a next PASIC!
