Anonymize the information as soon as the students graduate. Done! That way it can still be used for gaining insight without being traceable to any given student

- ivank 13y agoReidentification algorithms could still be used to identify students; see http://33bits.org/tag/de-anonymization/ http://33bits.org/tag/de-anonymization/
- dkarapetyan 13y agoThe same way RSA keys can be recovered from CPU noise/heat fluctuations. There is a right way to do anonymization and a wrong way. The same way there is a right way to do crypto and not leak information from side-channels.
- Someone 13y agoDecent crypto uses 128+ bits; it takes only 33 bits to identify any human on earth; less than 29 to identify a US citizen. It also is way harder to anonymize data _and_ allow for it to be queried in the aggregate.
- dkarapetyan 13y agoWhich 29 bits are those exactly?
- Someone 13y agohttp://33bits.org/about/ http://33bits.org/about/ 2^29 is about 500 million.
