Trust broker system for managing and sharing trust levels

1. A trust broker system which enables a relying party to control network service access of a client device, the trust broker system comprising:

one or more computing devices configured to maintain a trust ledger including a trust account balance (TAB) associated with each user of a set of users, wherein:

the TAB associated with each user of the set of users represents a value used to determine whether a respective user is permitted to access a resource, and

by maintaining the trust ledger, the one or more computing devices enable each device of a set of devices having access to the trust broker system to:

receive, by a respective device of the set of devices, a request for a TAB associated with a user of the set of users;

determine, based on the trust ledger, the TAB associated with the user of the set of users; and

output, by the respective device of the set of devices, information indicative of the TAB associated with the user of the set of users; and

a trust assessor configured to:

receive, from the one or more computing devices, an indication that the TAB associated with the user of the set of users is updated;

reassess the TAB associated with the user by comparing the TAB with a TAB threshold; and

in response to the TAB being less than the TAB threshold, execute a smart contract to initiate a host check to increase the TAB associated with the user of the set of users.

2. The trust broker system of claim 1 , wherein by maintaining the trust ledger, the one or more computing devices enable the client device to:

receive a request from a user of the set of users to authenticate the user with a blockchain client of the client device, wherein the client device is included in the set of devices having access to the trust broker system; and

determine a TAB associated with the user, wherein the TAB associated with the user is recorded in the trust ledger.

3. The trust broker system of claim 2 , wherein:

by maintaining the trust ledger, the one or more computing devices enable the client device to:

receive, by a client application of the client device, an application resource request from the user of the set of users; and

output, from the client application, the application resource request, and

by maintaining the trust ledger, the one or more computing devices enable the relying party to:

receive the application resource request;

determine, based on the trust ledger, the TAB associated with the user of the set of users; and

in response to the TAB associated with the user being greater than or equal to a TAB threshold, process the application resource request.

4. The trust broker system of claim 3 , wherein by maintaining the trust ledger, the one or more computing devices enable the relying party to:

maintain a list that includes a number of application resource requests associated with each user of the set of users received by the relying party;

in response to the number of application resource requests associated with the user exceeding a threshold number of application resource requests, determine that a trust reassessment is required for the user; and

execute a smart contract to decrease the TAB associated with the user; and

distribute a TAB decrease transaction to each device of the set of devices having access to the trust broker system.

5. The trust broker system of claim 1 , wherein:

the TAB corresponding to each user of the set of users may be within a range from 0 to 1000; and

the TAB associated with each user of the set of users is modified at a TAB change rate.

6. The trust broker system of claim 1 , wherein the one or more computing devices comprise one or more blockchain miner devices.

7. The trust broker system of claim 1 , wherein by maintaining the trust ledger, the one or more computing devices enable the client device to:

execute a first smart contract with an identity provider (IdP) blockchain client of an identity broker device to authenticate the user with an IdP service of the identity broker device;

based on authentication of the user by the IdP service, execute a second smart contract to initiate a TAB update transaction to change a TAB associated with the user; and

distribute the TAB update transaction to each device of the set of devices having access to the trust broker system.

8. The trust broker system of claim 7 , wherein the IdP service is included in the set of devices having access to the trust broker system.

9. The trust broker system of claim 7 , wherein the one or more computing devices are further configured to:

receive the TAB update transaction;

execute, in response to receiving the TAB update transaction, consensus algorithms to update the TAB associated with the user in the trust ledger, wherein the execution creates an updated trust ledger; and

distribute the updated trust ledger to each device of the set of devices having access to the trust broker system.

10. The trust broker system of claim 9 , wherein the consensus algorithms include a proof-of-work algorithm, a proof-of-stake algorithm, or a proof-of-time algorithm.

11. A method to enable a relying party to control network service access of a client device, the method comprising:

maintaining, using one or more computing devices, a trust ledger including a trust account balance (TAB) associated with each user of a set of users, wherein the TAB associated with each user of the set of users represents a value used to determine whether a respective user is permitted to access a resource, and

by maintaining the trust ledger, enabling each device of a set of devices having access to a trust broker system to perform:

receiving, by a respective device of the set of devices, a request for a TAB associated with a user of the set of users;

determining, based on the trust ledger, the TAB associated with the user of the set of users;

outputting, by the respective device of the set of devices, information indicative of the TAB associated with the user of the set of users;

receiving, from the one or more computing devices, an indication that the TAB associated with the user of the set of users is updated;

reassessing the TAB associated with the user by comparing the TAB with a TAB threshold; and

in response to the TAB being less than the TAB threshold, executing a smart contract to initiate a host check to increase the TAB associated with the user of the set of users.

12. The method of claim 11 , wherein by maintaining the trust ledger using the one or more computing devices, enabling the client device to perform:

receiving a request from a user of the set of users to authenticate the user with a blockchain client of the client device, wherein the client device is included in the set of devices having access to the trust broker system; and

determining a TAB associated with the user, wherein the TAB associated with the user is recorded in the trust ledger.

13. The method of claim 12 , wherein:

by maintaining the trust ledger using the one or more computing devices, enabling the client device to:

receiving, by a client application of the client device, an application resource request from the user of the set of users; and

outputting, from the client application, the application resource request, and

by maintaining the trust ledger using the one or more computing devices, enabling the relying party to:

receiving the application resource request;

determining, based on the trust ledger, the TAB associated with the user of the set of users; and

in response to the TAB associated with the user being greater than or equal to a TAB threshold, processing the application resource request.

14. The method of claim 13 , wherein by maintaining the trust ledger using the one or more computing devices, enabling the relying party to:

maintaining a list that includes a number of application resource requests associated with each user of the set of users received by the relying party;

in response to the number of application resource requests associated with the user exceeding a threshold number of application resource requests, determining that a trust reassessment is required for the user; and

executing a smart contract to decrease the TAB associated with the user; and

distribute a TAB decrease transaction to each device of the set of devices having access to the trust broker system.

15. The method of claim 11 , wherein:

the TAB corresponding to each user of the set of users may be within a range from 0 to 1000; and

the TAB associated with each user of the set of users is modified at a TAB change rate.

16. The method of claim 11 , wherein the one or more computing devices comprise one or more blockchain miner devices.
