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. The system may comprise a plurality of chains, such as an identity chain and an activity chain. In some aspects, identity data associated with a user may be used to generate an identity token for the user. The identity token may be transmitted to a plurality of computing devices for verification. Based on a verification of the identity token, the identity token may be stored in the identity chain. A request to perform an activity may also be received, and identity data associated with the user may be received in order to authenticate the user. The computing device may generate, based on the received identity data, 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.

Claims20

Dependent claims

A method comprising:

receiving, by a computing device, first identity data associated with a user;
generating, by the computing device and based on the first identity data associated with the user, a first identity token for the user;
transmitting, by the computing device and to a plurality of other computing devices, the first identity token for the user;
based on a verification of the first identity token for the user by one or more of the plurality of other computing devices, storing the first identity token for the user in an identity chain, wherein the first identity token for the user indicates a prior identity token stored in the identity chain;
receiving, by the computing device, a request to perform an activity;
in response to receiving the request to perform the activity, requesting, by the computing device, second identity data associated with the user;
receiving, by the computing device, the second identity data associated with the user;
generating, by the computing device and based on the second identity data associated with the user, a second identity token for the user;
based on a comparison of the second identity token to the first identity token, authenticating the user and generating an activity token for the activity;
and
storing the activity token for the activity in an activity chain, wherein the activity token indicates a prior activity token stored in an activity chain.

A computing device comprising:

a processor;
and
memory storing computer-executable instructions that, when executed by the processor, cause the computing device to:
receive first identity data associated with a user;
generate, based on the first identity data associated with the user, a first identity token for the user;
transmit, to a plurality of other computing devices, the first identity token for the user;
based on a verification of the first identity token for the user by one or more of the plurality of other computing devices, store the first identity token for the user in an identity chain, wherein the first identity token for the user indicates a prior identity token stored in the identity chain;
receive a request to perform an activity;
in response to receiving the request to perform the activity, request second identity data associated with the user;
receive the second identity data associated with the user;
generate, based on the second identity data associated with the user, a second identity token for the user;
based on a comparison of the second identity token to the first identity token, authenticate the user and generate an activity token for the activity;
and
store the activity token for the activity in an activity chain, wherein the activity token indicates a prior activity token stored in an activity chain.

11 more elements

A non-transitory computer readable medium storing instructions that, when read by a computing device, cause the computing device to:

receive first identity data associated with a user;
generate, based on the first identity data associated with the user, a first identity token for the user;
transmit, to a plurality of other computing devices, the first identity token for the user;
based on a verification of the first identity token for the user by one or more of the plurality of other computing devices, store the first identity token for the user in an identity chain, wherein the first identity token for the user indicates a prior identity token stored in the identity chain;
receive a request to perform an activity;
in response to receiving the request to perform the activity, request second identity data associated with the user;
receive the second identity data associated with the user;
generate, based on the second identity data associated with the user, a second identity token for the user;
based on a comparison of the second identity token to the first identity token, authenticate the user and generate an activity token for the activity;
and
store the activity token for the activity in an activity chain, wherein the activity token indicates a prior activity token stored in an activity chain.
