HI,
We have installed FPJS on our site that allows capturing FP information and analyze the performance of each Attribute. Each user we can identify with the phone number and therefore can measure the uniqueness of the FP and monitor the changes in the attributes.
We start analyzing the data and see cases when for the same user/browser some values are changing in very short period of time. (10-20 minutes).
Looking for advice on how to test and optimize the performance. What optimization steps to take?
For instance, we noticed that most attribute that changes are:
in languages changes looks like:
from [["ru"],["ru"]] to -> [["ru-RU"],["ru-RU","ru","en-US","en"]]
from [["ru"]] to -> [["ru-RU"]]
in fontPreferences changes looks like:
from {default=167, apple=167, serif=167, sans=144, mono=136, min=15, system=144} - interger values
to {default=164.71875, apple=164.71875, serif=164.71875, sans=145.90625, mono=132.625, min=10.296875, system=145.90625}
Other cases they just changed:
from {default=149.3125, apple=129.923828125, serif=149.3125, sans=144.0078125, mono=132.62158203125, min=9.33203125, system=146.09375}
to {default=149.3125, apple=153.53125, serif=149.3125, sans=144.0078125, mono=132.62158203125, min=9.33203125, system=146.09375}
What does it mean? This is not stable across browsers or there is other reasons? How can we stabilize the result of web fingreprint?
