Systems, devices, and methods are described herein for calculating a
trust score. The
trust score may be calculated between entities including, but not limited to, human users, groups of users, organizations, or businesses / corporations. A
system trust score may be calculated for an entity by combining a variety of factors, including
verification data, a
network connectivity score, publicly available information, and / or ratings data. A peer trust
score targeted from a first entity to a second entity may also be calculated based on the above factors. In some embodiments, the peer trust
score may be derived from the
system trust score for the target entity and may take into account additional factors, including
social network connections, group / demographic info, and
location data. Finally, a contextual trust score may be calculated between the first and second entities based on a type of transaction or activity to be performed between the two entities.
