Data Don't Have Feelings

This is an odd way to spin a fire at a server farm...

Fire at UID data centre, 20cr citizens' data at risk (Times of India)
The data centre on the third floor is a small subset of the main data centre in Bangalore, said the spokesman.

"Little data was being stored here. Nonetheless, no data is harmed as we have a back up at 3-4 locations across the country," the spokesman said.
So as not to single out the Times of India, it's worth noting that the Economic Times is running essentially the same article.

My question is how exactly, as asserted in the headline, is citizen data at risk?

Only two possibilities make sense.

The first possibility is that the data is at risk of being lost, deleted or destroyed by fire. If that's the case the "risk" is that all the staff work and the effort of those who waited in line to get an ID is wasted. But since it's backed up at 3-4 locations, that's not the case.

The other possibility is that is is less secure because of the fire, but burning data and/or destroying hardware doesn't make it less secure in the sense that it can be abused, it makes it more secure in the sense that it is useless. Even NO2ID knows that.

Another funny quote from the article...

"The accident puts a big question mark over safety of data being collected from about 1.2 billion Indian residents and being housed in risk prone facilities."

The only way this makes sense is if data have feelings. If they do, they might care about fire safety out of a sense of self-preservation but then again, they might not.


The Times of India and The Economic Times frequently do top-rate work on UID. This article is just strange. Fun, but strange.

Securing Corporate Data in the Cloud: Biometric Logical and Physical Access Control

How to make information stored in the cloud robustly safe (The Guardian)

Most articles like this mention biometrics only in the context of physical access control at the data center, which is important. You don't hear as much about biometrics for controlling access to data stored in the cloud, though, and that's too bad because biometrics for logical access control could make the cloud a lot safer for businesses and their customers.

At a data center, physical access control prevents this (access to places)...

Logical access control is for this (access to information)...


...and tricking out data centers like Fort Knox, along with other logistical challenges ensures that there are a lot more of the latter than the former.

In networked logical access control solutions, the biometric sensor hardware is a part of the security. In the standard Username/Password regime, the hardware used, the keyboard, offers no additional security. With username/password authentication, a hacker needs only a keyboard to fill in the proper fields and she gains access to the network. If that username/password is a superuser or administrator credential, there's may be some turnover in the CTO function.

Biometric authentication is very different animal because with biometrics, the hardware layer does provide extra security. If the hacker steals a biometric or unencrypted biometric template (a long character string), she can't just type it in even if she finds the place in the programming that handles the template. The template resulting from a verification attempt is like a single use password created during the interaction of a physical object (body part) with certain known sensor.

For organizations using cloud services, requiring biometric authentication to authorize access to any database storing usernames/passwords should dramatically decrease the risk of high profile data breaches or other damaging hacks.

But even if every human account used biometrics for logical access control, some version of username/password verification will be around for a long, long time because username/password is a cheap, well-understood, flexible technology that supports certain access control models that biometrics does not. For one thing, people aren't the only things that claim an identity before accessing IT systems — computers do it, too, and they don't have biometrics.

The challenge that system designers now face is to identify where using Username/Password is too dangerous, and where biometrics can be used to reduce risk to an acceptable level. This requires identifying everything currently authenticated with a username/password and a determining which of these things are more efficiently protected using biometric authentication, then implementing the change. This is far easier said than done.

Requiring biometric verification of all human Administrator logins would be a good start, though. There aren't (or shouldn't be) that many of them. They are tech savvy, so they should be able to adapt to the new security environment quickly. They should have an understanding of why the extra step is worth the effort. It's their responsibility to keep the keys of the kingdom and they're the ones on the hot seat when the CEO is out apologizing to all and sundry following a data breach.
