Conclusions

•Wide variance in translation of privacy‐iti l i f ticritical information. •Google+ and LinkedIn widely translatedFli k id l l d f i•Flickr widely translated except for its Privacy Policy

•Privacy‐critical info not translated into many languages on Facebook and Twitter

•These are the crowdsourced translations

31

Conclusions

•Having versions of privacy information only i E li h d l t th l din English and select other languages does not provide adequate notice

•We believe it is incumbent on sites to ensure the availability of translated privacy‐critical information

32

Potential Steps Forward

•Prioritize translating privacy information

•Incentive (e.g. pay people) to translate“Th d”•“The crowd”

•Professional translators

•Crowd‐corrected machine translation

•Language‐independent notice (e.g. P3P)g g p g
