OpenID is an open and promising Web single sign-on (SSO) solution. This work investigates the challenges and concerns web users face when using OpenID for authentication, and identifies what changes in the login flow could improve the users' experience and adoption incentives. We found our participants had several behaviors, concerns, and misconceptions(More)
OpenID and OAuth are open and simple Web SSO protocols that have been adopted by major service providers, and millions of supporting Web sites. However, the average user’s perception of Web SSO is still poorly understood. Through several user studies, this work investigates users’ perceptions and concerns when using Web SSO for authentication.(More)
OpenID is an open and promising Web single sign-on solution; however, the interaction flows provided by OpenID are inconsistent, counter-intuitive, and vulnerable to phishing attacks. In this work, we investigated the challenges web users face when using OpenID for authentication, and designed a phishing-resistant, privacy-preserving browser add-on to(More)
One of the basic conditions, enabling the healthy living in flat houses, is the securing of thermoisolation properties of peripheral building elements. The presented study deals with the verification of thermoisolation properties by the method using the liquid crystal thermoindicators and thermographic sheets. The applied method is effective, sufficiently(More)
The study deals with time degradation changes of chromatic temperature characteristics and chromatically active temperature intervals of LC thermochromic sheets of inland provenance. The method applied is relatively simple, gives quite reproducible results and can be utilized for verification of chromatic temperature characteristics of thermographic sheets(More)
Recent research in the field of elastography has sought to expand displacement tracking to three dimensions. Once the 3-D volumes of displacement data have been obtained, they must be scan converted so that further processing, such as inversion methods to obtain tissue elasticity, can take place in Cartesian coordinates. This paper details an efficient and(More)
