Safety Tech Challenge Fund

The Safety Tech Challenge Fund will drive the development of innovative technologies that help keep children safe in end-to-end encrypted environments, without compromising user privacy. 

Through the Fund, the UK Government is awarding five organisations up to £85,000 each to prototype and evaluate innovative ways in which sexually explicit images or videos of children can be detected and addressed within end-to-end encrypted environments, while ensuring user privacy is respected. 

Change is possible. The Safety Tech Challenge Fund presents a way in which we can come together from across sectors - government, tech industry, academia and non-profits - to test the art of the possible and to share best practice. 

Further information about the Fund, and its underlying technical principles, can be found in our Supplier Guidelines.
