Abstract
Information Security often works in antipathy to access and useability in communities of older citizens. Whilst security features are required to prevent the disclosure of information, some security tools have a deleterious effect upon users, resulting in insecure practices. Security becomes unfit for purpose where users prefer to abandon applications and online benefits in favour of non-digital authentication and verification requirements. For some, the ability to read letters and symbols from a distorted image is a decidedly more difficult task than for others, and the resulting level of security from CAPTCHA tests is not consistent from person to person. This paper discusses the changing paradigm regarding second tier applications where non-essential benefits are forgone in order to avoid the frustration, uncertainty and humiliation of repeated failed attempts to access online software by means of CAPTCHA.
