Expendable access control
View Patent ↗A computer implemented method of a resource provider for access control for a restricted resource in a network connected computer system, wherein a blockchain data structure accessible via the network stores digitally signed records validated by network connected miner software components including a provider record associated with the resource provider, the method including: identifying an access control role definition for access to the resource, the role including a specification of access permissions; receiving a request from a resource consumer for access to the resource; communicating, to the resource consumer, an indication of a quantity of a cryptocurrency required for access to the resource; and in response to a determination that the required quantity of cryptocurrency is transferred to the provider record in the blockchain, the transfer being caused by a blockchain transaction including an identification of the role and the transaction being validated by a miner component, granting the consumer access to the resource in accordance with the role definition.
1. A computer implemented method of a resource provider for access control for a restricted resource in a network connected computer system, wherein a blockchain data structure accessible via the network stores digitally signed records validated by network connected miners including a provider record data structure associated with the resource provider, the method comprising:
identifying an access control role definition for access to the restricted resource, the access control role definition including a specification of access permissions for a class of access based on a role, the access control role definition selected from a plurality of access control role definitions stored in an authorization server, wherein, once identified, the access control definition for access to the restricted resource is stored by the resource provider;
receiving a request from a resource consumer for access to the restricted resource;
communicating, to the resource consumer, an indication of a quantity of cryptocurrency required for access to the restricted resource; and
in response to a determination that the required quantity of cryptocurrency is transferred to the provider record data structure in the blockchain, the transfer being caused by a blockchain transaction including comparing the access control role definition for access to the restricted resource to an access control role definition for the resource consumer, the access control role definition for the resource consumer being previously determined by the authorization server and the transaction being validated by a miner, granting, by the resource provider, the resource consumer access to the restricted resource in accordance with the access control role definition.
2. The method of claim 1 , wherein the identification of the access control role definition in the blockchain transaction is obfuscated such that the identification is not discernible without a shared secret.
3. The method of claim 1 , wherein the cryptocurrency is a pre-existing cryptocurrency in which some quantity of tradeable units of the pre-existing cryptocurrency is associated with the restricted resource or the resource provider.
4. The method of claim 1 , further comprising determining the quantity of cryptocurrency required for access to the restricted resource based on a state of operation of the resource provider.
5. The method of claim 1 , further comprising determining the quantity of cryptocurrency required for access to the restricted resource based on one or more of: an extent of consumption of the restricted resource; or a degree of contention for access to the restricted resource.
6. A network connected computer system for access control for a restricted resource, wherein a blockchain data structure accessible via the network stores digitally signed records validated by network connected miners including a provider record data structure associated with a resource provider, the system comprising:
a hardware processor and a data store, wherein the hardware processor is adapted to:
identify an access control role definition for access to the restricted resource, the access control role definition including a specification of access permissions for a class of access based on a role, the access control role definition selected from a plurality of access control role definitions stored in an authorization server, wherein, once identified, the access control definition for access to the restricted resource is stored by the resource provider;
receive a request from a resource consumer for access to the restricted resource;
communicate, to the resource consumer, an indication of a quantity of a cryptocurrency required for access to the restricted resource; and
in response to a determination that the required quantity of cryptocurrency is transferred to the provider record data structure in the blockchain, the transfer being caused by a blockchain transaction including comparing the access control role definition for access to the restricted resource to an access control role definition for the resource consumer, the access control role definition for the resource consumer being previously determined by the authorization server and the transaction being validated by a miner, grant, by the resource provider, the resource consumer access to the restricted resource in accordance with the access control role definition.
7. A non-transitory computer-readable storage medium storing a computer program element comprising computer program code to, when loaded into a computer system and executed thereon, cause the computer to perform the method as claimed in claim 1 .
