A Benchmark for Designing Usable and Secure Text-based Captchas

An automated public Turing test to distinguish between computers and humans known as CAPTCHA is a widely used technique on many websites to protect their online services from malicious users. Two fundamental aspects of captcha considered in various studies in the literature are robustness and usability. A widely accepted standard benchmark, to guide the text-based captcha developers is not yet ...

Designing Highly Usable Web Applications

Web page (see Figure 36.2; b-3) representing the possible navigational targets (Tasks, Reports, and Contacts). However, as the label connected as, represented by the navigational link LI96 is a source link (empty arrow), the login information is showed in the same user’s generated home page (see Figure 36.2; b-3). The following usability metrics can be applied to the Navigational Model in Figur...

Designing Usable Spontaneous Device Association

Spontaneous interaction is one of the prerequisites for ubiquitous computing. It enables devices to share resources without premeditation. However, before devices can exchange data, they are required to establish a virtual connection; a process known as device association. Over the years, researchers have demonstrated many techniques for associating devices; nonetheless, their designs were most...

Designing Usable Bio-information Architectures

Bioinformatics websites offer to the life science large community repositories of information ranging from genes, genomes, proteins, experimental data and their integration, with the aim of supporting the elucidation of biological processes. As the bioinformatics community increasingly relies on the design, sharing and use of web-based resources, it is important to systematically address the us...
