Vis-à-vis Cryptography: Private and Trustworthy In-Person Certifications

The growing role of mobile devices in previously face to face interactions presents new domains for cryptographic applications. At the same, time the increased role of digital systems raises new security and privacy issues. With some thirty thousand notifications sent, inSPOT.org's electronic notification of exposure to sexually transmitted infections is one such concerning development. This paper explores those concerns, the features of an ideal service for both notification and certification, and outlines protocols for cryptographic solutions.
