Publishing Open Data? You Need Perturbation
Privacy is more than just Personally Identifiable Information
Removing personal identifying information is not enough to achieve true statistical disclosure control.
I know my neighbour's health records are in an open dataset...
I know that she has three children and is in her mid 30s. By combining these facts, I can narrow down the results and easily locate her in the dataset.
Once I have located her...
It's easy for me to discover confidential information about her medical history.
You Need Perturbation
To protect the people in your data, you need a robust confidentiality solution that automatically applies statistical disclosure control to everything you release.
We have worked in collaboration with government agencies around the world to develop a unique data confidentiality solution—perturbation—that addresses privacy concerns without compromising the flexibility or usefulness of your data.
It’s in use by statistical agencies around the world who use our SuperWEB2 solution for data dissemination, including the Australian Bureau of Statistics, who use perturbation to protect the privacy of the citizens of Australia in the published census data.
