Abstract

Aspects of the disclosure relate to a system and method for cryptographically transmitting and storing identity tokens and/or activity data among spatially distributed computing devices. Identity data associated with a user may be used to generate an identity token for the user. Based on a verification of the identity token, the identity token may be stored in an identity chain. A request to perform an activity may also be received. The computing device may generate, based on identity data associated with the user, an identity token for the user. The identity token may be compared to the identity token stored in the identity chain, and the user may be authenticated based on the comparison. An activity token for the activity may be generated, and the activity token may be stored in the activity chain.
