|# i3lock blurred screen inspired by /u/patopop007 and the blog post|
|# Timings are on an Intel i7-2630QM @ 2.00GHz|
|# scrot (optional but default)|
|SCREENSHOT="scrot $IMAGE" # 0.46s|
|# Alternate screenshot method with imagemagick. NOTE: it is much slower|
|# SCREENSHOT="import -window root $IMAGE" # 1.35s|
|# Here are some imagemagick blur types|
|# Uncomment one to use, if you have multiple, the last one will be used|
|# All options are here: http://www.imagemagick.org/Usage/blur/#blur_args|
|#BLURTYPE="0x5" # 7.52s|
|#BLURTYPE="0x2" # 4.39s|
|#BLURTYPE="5x2" # 3.80s|
|BLURTYPE="2x8" # 2.90s|

|# Get the screenshot, add the blur and lock the screen with it|
|convert $IMAGE -blur $BLURTYPE $IMAGE|
|i3lock -i $IMAGE|

how are the time measurements done?

@z3t0 probably a stopwatch or something...

I like it but it takes a bit of time to blur ...bit insecure

You can use imagemagick's import command to screencap as well, reducing the number of required packages.

A quick suggestion to improve the time to render the blurred image, you could reduce the size of the screen cap before applying the blur:
convert $IMAGE -resize 50%
convert $IMAGE -blur $BLURTYPE $IMAGE
Then put back to 200% to get back to orginal size
convert $IMAGE -resize 200%

Inspired from this project, here a little boost i3lock++

I know it's been some time since you published this gist. I used this method until today, but because I use an older computer it would take me 2-5 seconds to take the screenshot, add the effect and then run the i3lock. i3lock-blur flickers and doesnt work in my computer.
I've forked scrot and added a blur option and an option to add an icon here: darddan/scrot
scrot -B 5 -i icon.png output.png generates a blurred screenshot with an icon over it in about 300 milliseconds.
