Identity Management (IDM) is a discipline that tries to supervise how passwords are protected and verified, how IT departments decide what files you have access to, etc.
It's a new field--they're still debating the name, they haven't really defined the limits, and they don't know where the concept should sit inside organisations. Perfect for what we're doing here. We've looked at very long time series, for things such as Mars and Alzheimer's Disease and battlefield injuries. We've looked at timelines for fairly new fields, such as nanotechnology. Here is a field that is just being born.
The first academic work starts to appear in 2000, according to Scirus, and there are only 612 academic publications with the phrase "identity management" in the title, abstract or text overall. Truly nascent.
There have been 1,172 patents filed with the phrase "identity management" in the title, abstract or text overall.
In the extended post below, I show the figures and explain a bit more about how I calculate the compound annual growth rate, and show an alternative means of calculating it.
Using the method I've employed throughout this weblog, the growth rate for academic publications is 34.93%, which would double every 2.31 years, and the growth rate for patent applications is 32.93%, which would double every 2.44 years. and I would then write 'Hooray! We have another winner!'
But the alternative means of calculating growth would look even better, showing growth in academic publications of 71.54% and a doubling time of 1.28 years, and for patents, CAGR of 71.37% and a doubling time of 1.29 years.
I'm going to stick with my method, but if you want to recalculate all of the figures, the tools to do so are here. Click to see the numbers and the explanation.
