Open Geo Hub: Spatial Data Anonymization Made Easy
If you’re interested in open data and want to try anonymizing some of your spatial datasets here’s some good news for you:
We have launched a GIS web app where you can anonymize your point data for free. The app can be accessed here: www.geohub.site
Using this tool you can anonymize your data using two methods:
- a simple but efficient donut anonymization
- An advanced context sensitive anonymization algorithm.
The tool is based on the method developed in the following study:
Hasanzadeh, K., Kajosaari, A., Häggman, D., & Kyttä, M. (2020). A context sensitive approach to anonymizing public participation GIS data: From development to the assessment of anonymization effects on data quality. Computers, Environment and Urban Systems, 83, 101513.
This is a beta version of the tool and all feedback are welcome at this stage. If you have any inquiries, please find the contact information on www.geohub.site.
The tool currently only supports point data. More functionalities will be added to the hub in future.
