The OPN Notification Protocol

Consent By Design

Consent by Design is a privacy and surveillance ‘OPN Notification Protocol’ for generating privacy by default by signalling privacy by default. The OPN Networks is design to enable and maintain privacy expectation by tracking changes to notice, policy and the legal compliance status of a controller profile. This is used to personalise privacy notices by context and person to maintain a shared understanding of the expected privacy state.

Making Privacy easy to use

By creating a transparency signal and set of standard conditions for its use, privacy expectations are set by default, automating digital transparency in context so people can see, understand, and manage their own digital privacy. In first engagement with a Consent By Design service, the digital transparency settings are explained and the privacy expectation is set. A consent receipt is generated by default, so this expectation is remember and automatically used when in this context again in the future. The OPN Protocol makes the notification of complicated privacy processing simple and the notifications of changes to privacy personalised per context and person. Making privacy easy for people, makes privacy easy for a Data Controller and greatly reduces the privacy and security risks of digital surveillance technology.


Consent byDesign is a Notification Protocol for maintaining privacy expectations with privacy by design. It is used to streamline customer experience, create efficiencies in personal data control to protect business operations and brand with a reduction in privacy and surveillance risks people face with digital identity technologies.


Privacy by default, means people can expect a high level of privacy automatically and engage in trustworthy data sharing according to context. The OPN Notification protocol puts people in control by default, builds privacy awareness dynamically and iteratively providing companies with a new generation of engagement tools for people first information sharing.
