Recessive Social Networking: Preventing Privacy Leakage against Reverse Image Search

Jiajie Zhang, Bingsheng Zhang, Jiancheng Lin
2019 2019 IEEE European Symposium on Security and Privacy Workshops (EuroS&PW)  
This work investigates the image privacy problem in the context of social networking under the threat of reverse image search. We introduce a new concept called recessive social networking.  ...  We, for the first time, ultilize adversarial example technique as a defensive mechanism to protect image privacy against content-based image search algorithms in the context of social networking.  ...  This recessive mechanism can be considered as a middleware between users and OSN.  ...

Maintaining Compatibility in an Innovation Infrastructure [chapter]

Steinar Kristoffersen
2006 Advances in Information Systems Development  
This paper should be considered a first step towards extensively theorizing and implementing this concept in the supporting 'innovation infrastructure'.  ...  The aim of the project was to test whether commercially available off-the-shelf components (COTS) could be assembled for a fully-functional wearable configuration that would meet the harsh demands of artic  ...  Locations were overlaid on the map. • Route planning systems, to show the squad members the intended path (as a line on the map). Routes are overlaid on the map.  ...
