Talk Title: Better Bug Reporting with Better Privacy

Talk Abs

tract:
Software vendors collect bug reports from customers to improve the quality of their software. These reports should include the
inpu

ts that make the software fail to enable vendors to reproduce
the bug

. However vendors rarely include these inputs in reports
because the

y may contain private user data. We describe a solution
to this proble

m that provides software vendors with new input values
that satisfy the
conditions required to make the software follow the
same execution pat

h until it fails but are otherwise unrelated with the
original inputs.
These new inputs allow vendors to reproduce the bug
while revealing le

ss private information than existing approaches.
Additionally we provi

de a mechanism to measure the amount of
information revealed in an erro

r report. This mechanism allows
users to perform informed decisions on

whether or not to submit
reports. We implemented a prototype of our sol

ution and evaluated
it with real errors in real programs. The results s

how that we can
produce error reports that allow software vendors to re

produce
bugs while revealing almost no private information.
