Abstract: Systems and methods for securing communication between users possessing user-wearable mementos are provided. One example computing system includes a data subsystem holding instructions executable by a processing subsystem. The example instructions are configured to assign a set identifier to a set of user-wearable mementos set that uniquely distinguishes the set from any other set and to encode the set identifier within a design for the set in response to receipt of a request to obtain the set. The instructions are also configured to provide access to a user communication interface in response to an access request for a set profile associated with the set, the access request including the set identifier as obtained from a particular user-wearable memento bearing the design.
