By eavesdropping on a user's query in a sensor network, an adversary can deduce both the user's current location and his/her location of interest. Issuing k queries instead of one (our "k-query" scheme) protects the privacy of the user's location of interest, but facilitates the adversary...
Intermediation and Governance of Digital Flows: Canadian Internet Service Providers as Instruments of Public PolicyDownload

Web security has become a critical issue due to the rising reliance of people on diverse types of online transactions. A CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) is a security mechanism that is widely used to maintain the security of web services by...
A CAPTCHA is an automatically generated test designed to distinguish between humans and computer programs; specifically, they are designed to be easy for humans but difficult for computer programs to pass in order to prevent the abuse of resources by automated bots. They are commonly seen...
Herein, we propose generating CAPTCHAs through random field simulation and give a novel, effective and efficient algorithm to do so. Indeed, we demonstrate that sufficient information about word tests for easy human recognition is contained in the site marginal probabilities and the...
