Subject: disable battery status updater
|
||
|
|
|
||
|
|
The W3C Battery Status API[1] has quite a laughable statement:
|
||
|
|
|
||
|
|
"The information disclosed has minimal impact on privacy or
|
||
|
|
fingerprinting, and therefore is exposed without permission grants".
|
||
|
|
|
||
|
|
Along comes a paper "The leaking battery, A privacy analysis of the
|
||
|
|
HTML5 Battery Status API."
|
||
|
|
|
||
|
|
Clean up after the W3C and disable the battery status updater which
|
||
|
|
could be used to identity users[2].
