  Persons with visual impairments have often been a soft target for
cybercriminals, and they are more susceptible to cyber attacks in the digital
environment. The attacks, as mentioned above, are because they are
visually/aurally exposed to the other sighted users. Visually impaired computer
users suffer from secrecy and privacy issues on digital platforms. This paper
proposes a mechanism termed BEEMA(Braille adapted Enhanced PIN Entry Mechanism
using Arrow keys) to help people with visual impairments. We have studied
various security attacks on visually impaired users and proposed a mechanism
named BEEMA that provides a rigid braille-adapted text input for people with
visual impairments. This mechanism allows users to enter a PIN number on any
website that requires a PIN number. The proposed model is implemented as a
browser plugin which can be accessed easily. We have conducted sessions with
visually impaired users to study the mechanism's performance. The proposed
BEEMA model has shown encouraging results in the user study. Resilience of
BEEMA against various attacks is also explored in this paper.
