Ok but the lab has access to the unencrypted data? You haven't removed the requirement that the user needs to trust the lab with their raw genome markers. This entire operation hinges on the lab's trustworthiness, does it not?
We are developing a solution that will allow cryptography for DNA molecules, allowing DNA to be secure in any lab. It fits well with Monadic's front end.
At-home sequencing could be a game changer.
The other reply also mentions molecular cryptography which could provide really strong anonymity and privacy guarantees. We hope to do a PoC accordingly some time in the neat future.
