CAPTCHA Accessibility Study of Online Forums
The rise of online forums has benefited disabled users, who take advantage of better communications and more inclusion into society. However, even with accessibility laws that are supposed to provide disabled people the same equal access as non-disabled users, sites have erected technical barriers, such as CAPTCHAs, that prevent users from taking full advantage of site capability. This study analyzes 150 online forums to determine if sites use CAPTCHAs, and what types are used. Each variety presents accessibility problems to disabled users and the results of the research show that most sites use text-based CAPTCHAs, but rarely provide alternatives that would help users with visual disabilities. The research presents alternatives that site designers may wish to consider in order to allow more disabled users to access their sites
The Internet of Hackable Things
The Internet of Things makes possible to connect each everyday object to the

privacy perspective, this tsunami of connectivity represents a disaster, which
makes each object remotely hackable. We claim that, in order to tackle this
issue, we need to address a new challenge in security: education
Securing the Elderly: A Developmental Approach to Hypermedia-Based Online Information Security for Senior Novice Computer Users
Whilst security threats to the general public continue to evolve, elderly computer users with limited skill and knowledge are left playing catch-up in an ever-widening gap in fundamental cyber-related comprehension. As a definable cohort, the elderly generally lack awareness of current security threats, and remain under-educated in terms of applying appropriate controls and safeguards to their computers and networking devices. This paper identifies that web-based computer security information sources do not adequately provide helpful information to senior citizen end-users in terms of both design and content
