A nice article (that our researcher Lee Tobin contributed to) in The Irish Times newspaper on how wearable technology might impact our working lives. Here is an excerpt:

” …Wearable technologies are nothing new. The Google Glass consumer-oriented product allows owners to do many of the things they could do on their tablet with a pair of mock spectacles.

Then you have apps such as FitBit, which track your activity, so you can feel better about yourself as you walk home from the pub.

Likewise there are numerous wearable technologies used to monitor patients with various health conditions.

So who’s to say this kind of technology couldn’t be used in other settings? To time an employee’s smoke break, for example, or to alert the boss when someone is spending too much time chatting at the water cooler.

We are already living in the age of the “quantified self”. So it was only a matter of time before business bought in…”

A paper Lee Tobin, Ahmed Shosha and Pavel Gladyshev wrote has just been accepted to the Digital Investigation journal, it details an efficient and time economical way of reverse engineering a piece of hardware (a CCTV system in this case study paper).



Reverse engineering a CCTV system, a case study.


Given a disk image of a CCTV system with a non-standard file system, how is the data interpreted? Work has been done in the past detailing the reverse engineering of proprietary file systems and on the process of recovering data from CCTV systems. However, if given a disk image without the CCTV system itself, or if under time constraints, the task becomes much more difficult. This paper explains a different approach to recovering the data and how to make sense of data on a CCTV disk. The method does not require extensive reverse engineering of the CCTV system, or even to have access to the CCTV system itself.

More on this when it’s published…
