Can we build meaningful sequences out of the calls

[birdsarah]

Can we build code, that takes the time-stamped calls, (and the col/line number) and generates something useful from it?

• I’m thinking not only of a time sequence but also capturing loops in the code - where you go back to the same place again
  • Can this enable us to detect the same fingerprinting script even if it was minified differently (so col and line numbers are different, but the shape is the same).
  • I’m interested in finding the same script that might execute differently in different places: guessing it’s more likely to be different on different hardware - but may be different on different pages.
• Also maybe there are some common sequences of steps, ie. fingerprint.js is called from the main site, but it dispatches to A.js, B.js etc.

Note that there is no guarantee that execution time would be similar to code order, calls from different asyncronous functions could be interleaved, this would be very speculative investigation to see if we can get additional meaning out of the code.

Additionally, we are hoping to add an increment counter to future data collection.
