Shiny user fingerprint (md5 hash of browser characteristics) and ip address demo. The .R files are in the working directory ("./"), the .js files must be placed in ./www/js/ to be accessible. I wrote the R code, which I will release under the same WTF license as the jqfp.js library is released under.

| // Browser fingerprinting is a technique to "mark" anonymous users using JS | |
| // (or other things). To build an "identity" of sorts the browser is queried | |
| // for a list of its plugins, the screen size and several other things, then | |
| // hashes them. The idea is that these bits of information produce an unique | |
| // "fingerprint" of sorts; the more elaborate the list of data points is, the | |
| // more unique this fingerprint becomes. And you wouldn't even need to set a | |
| // cookie to recognize this user when she visits again. | |
