BEEMA: Braille Adapted Enhanced PIN Entry Mechanism using Arrow keys

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.
