Connected: To Everyone And Everything, Katherine Albrecht, Katina Michael

Associate Professor Katina Michael

The activist group CASPIAN (Consumers Against Supermarket Privacy Invasion and Numbering) was founded in 1999 by Katherine Albrecht, the very same year that Kevin Ashton co-founder and executive director of the then Auto-ID Center at MIT made a presentation to Proctor & Gamble with a title that included the phrase “Internet of Things”. According to Ashton, “the most numerous and important routers of all” are people but people have limitations and are not very good at capturing data about objects in the physical world. In 2001, Ashton’s automatic identification vision had become a lot clearer. At the Auto-ID Center during …

Social Implications Of Wearable Computing And Augmediated Reality In Every Day Life (Ieee Symposium On Technology And Society, Istas13), Katina Michael

Associate Professor Katina Michael

It was in July 2012 that Steve Mann and I corresponded on the possibility of hosting a conference on wearable computing in Toronto, Canada. Steve had just returned home from a family holiday to France and publicly blogged about an unfortunate incident that had happened to him while away. On 17th July 2012 he posted: “Physical assault by McDonald’s for wearing Digital Eye Glass”. We both knew the timing was right for such an event that was not just a technical engineering or applied orientation on the theme of smart worlds, but an event that would grapple with the dichotomies …

Relations Among Privacy Notions For Signcryption And Key Invisible "Sign-Then-Encrypt", Yang Wang, Mark Manulis, Man Ho Allen Au, Willy Susilo

Faculty of Engineering and Information Sciences - Papers: Part A

Signcryption simultaneously offers authentication through unforgeability and confidentiality through indistinguishability against chosen ciphertext attacks by combining the functionality of digital signatures and public-key encryption into a single operation. Libert and Quisquater (PKC 2004) extended this set of basic requirements with the notions of ciphertext anonymity (or key privacy) and key invisibility to protect the identities of signcryption users and were able to prove that key invisibility implies ciphertext anonymity by imposing certain conditions on the underlying signcryption scheme.

This paper revisits the relationship amongst privacy notions for signcryption. We prove that key invisibility implies ciphertext anonymity without any additional restrictions. …

Privacy-Enhanced Keyword Search In Clouds, Miao Zhou, Yi Mu, Willy Susilo, Man Ho Allen Au

Faculty of Engineering and Information Sciences - Papers: Part A

The advent of cloud computing has dramatically changed the IT scene, as it offers cost savings and improvements to major operations. Nevertheless, the major obstacle relies on the effort on how to secure sensitive data files that are outsourced to the cloud environment. To ensure confidentiality, the sensitive data are usually encrypted prior to being outsourced. Nevertheless, effective data utilization remains a challenging task and there is a clear need for a secure and efficient searching mechanism over the encrypted data in the cloud, to increase the us-ability of the secure cloud environment. Unfortunately, existing work in the area of …
