## AI overview

The post discusses a Dutch government tender for privacy-sensitive Corona contact tracing technologies and a submitted proposal to build an open-source, scalable backend. The proposed backend would let apps query infected keys and authorized health care professionals submit them, with features including rollback, authorization checks, checkpointing, incremental updates, DoS filtering, high availability, and geo-redundancy.

## Source excerpt

bert@hubertnet.nl / @bert_hu_bert / LinkedIn Very quick post. The Dutch government just launched a tender for "digital technologies that can help with Corona". The tender includes words on privacy sensitive contact tracing, it explicitly refers to PEPP-PT, the Pan-European Privacy-Preserving Proximity Tracing project. Responses are due on Tuesday the 14th of April, 12:00 (noon). The question/answer form asks if you can do a demo on the 18th of April and have something that could be rolled out on the 28th.
