I'll be interested in understanding the technical safeguards as well, since I am breaking my head on how to do this. One of my projects was about doing OCR on some confidential satellite images and we didn't want to outsource the OCR process solely because we couldn't figure out a scalable way to obfuscate data selectively in images. One early attempt was to recognize numbers using MNIST, get the boundary and clip that boundary with a similar sized black square. This doesn't work for all forms of text though.
- jlgaddis 9y agoWhat text were you reading from a satellite?
- mulmen 9y agoLicence plates, credit card numbers, text messages, your page number in Game of Thrones, normal spy satellite stuff. /s Seriously though maybe the text wasn't in the image as much as metadata attached to it? Something like the lat/long and time of the image? I don't really know, it's a good question.
- deepGem 9y agoOk these were regular land images (I think at 10m resolution) which had some text descriptions on the images. We deemed the text to be confidential enough not to outsource. Def, not spy satellite stuff :)
- ocrcustomserver 9y agoAre you still interested in this? I might be able to help.
- deepGem 9y agoI should clarify, we didn't use satellites directly, we just used the images given by a third party.
