TACo – Threshold Access/Action Control – is an open source public good; cryptographic infrastructure to undergird a non-surveilling, non-rent-seeking, non-exploitative internet.
TACo offers two primary services,
(i) Access Control – under what conditions is data decryptable?
(ii) Action Control – under what conditions is a transaction executable?
From an app developer's perspective, TACo is a straightforward and affordable plugin. Once integrated, TACo can enforce user-authored policies over who or what can (i) access or (ii) act on sensitive data – without single points of failure, data custodians, or centralized authorities.
This is possible thanks to the TACo network; an array of independently-controlled nodes each running the TACo client. Apps that have integrated the plugin connect to the network via the taco-web API. Groups of TACo nodes respond to user requests by collectively validating (i) sharing or (ii) signing policies. Specifically, nodes individually verify the requestor's fulfillment of pre-specified conditions, before providing the necessary fragment of (i) decryption material or (ii) signature, enabling the requestor's access or action respectively.
Without relying on centralized servers, TACo empowers the application user to truly control the conditions under which their data is accessible: by whom, for how long, and contingent on any digital source of truth.
For example: share my archive of evidence with journalists if I do not check-in over the next 7 days.
