  Symmetries play a crucial role in ubiquitous systems found in Nature. In this
work, we propose an elegant approach to detect symmetries by measuring quantum
currents. Our detection scheme relies on initiating the system in an
anti-symmetric initial condition, with respect to the symmetric sites, and
using a probe that acts like a local noise. Depending on the position of the
probe the currents exhibit unique signatures such as a quasi-stationary plateau
indicating the presence of meta-stability and multi-exponential decays in case
of multiple symmetries. The signatures are sensitive to the probe and vanish
completely when the timescale of the coherent system dynamics is much longer
than the timescale of the probe. These results are demonstrated using a
$4$-site model and an archetypal example of the para-benzene ring and are shown
to be robust under a weak disorder.
