Guest post: Cantabular: a new use-case for OpenStreetMap

A guest post by Ciáran Staunton. OpenStreetMap is not merely a map of roads, buildings, land uses, coastal areas and mountain tops.

Go Cantabular!

We decided to use the Go programming language (also known as Golang) to build Cantabular and have found it a great fit. It’s compact, readable, secure and fast. A perfect combination for a strategic product handling large amounts of sensitive data.

Our team here at Sensible Code have been busy for a few years working on an innovative privacy preserving technology called Cantabular. Cantabular uses highly performant implementations of disclosure control algorithms to protect data in real time as a user or researcher makes a query.

Modernising statistics — keeping data safe

Statistics professionals within public sector agencies take great care in how they process and protect personal data and this is reflected in the trust and respect they enjoy from their customers and the public at large. GDPR has thrown a further spotlight on governance around data confidentiality.
