  Based on the conviction of switching information from locally accessible to
locally hidden environs, the concept of hidden nonlocality activation has been
recently highlighted by Bandyopadhyay et al. in [Phys. Rev. A 104, L050201
(2021)]. They demonstrate that a certain locally distinguishable set of pure
quantum states can be transformed into an indistinguishable set with certainty
by allowing local operations and classical communication(LOCC). As this
transformation makes the set locally inaccessible to every subsystem, it is
defined as the activation of genuine hidden nonlocality. In this paper, we
observe that one class exhibits the previously mentioned nonlocal
characteristics, harnessing local operation by a single party, while in
contrast, another class demands cooperative endeavors among multiple local
observers to reveal its nonlocal attributes. From this vantage point, we
discern a stronger manifestation of locality, asserting that the latter class
is inherently more local than the former. This analysis sheds light on the
nuanced interplay between local and nonlocal phenomena within the framework of
quantum state discrimination. Furthermore, we also explore their significant
applications in the context of locally hiding information. Additionally, we
introduce the concept of \emph{``strong local"} set and examine its comparison
with different activable sets in terms of locality.
