Abstract
Visually impaired smartphone users are more vulnerable to cyber attacks such as visual/oral eavesdropping and shoulder surfing. One of the prime reasons is that these users are soft-target for the aforementioned attacks as they expose the visual and aural cues easier than the sighted users. Visually impaired people ultimately suffers from privacy threats in smart-phone platform. This paper proposes a braille inspired password entry model termed as VIBI to assist persons with visual impairments. We have examined the security attacks on smart-phones and proposed a multi-model system named VIBI, that provides the secure braille pattern based text input for persons with visual impairment. The user enters the password in an interface designed with inspirations from braille by tapping many times on touch screen with their fingers. Users can enter password in both portrait landscape orientations. We have conducted sessions with visually impaired participants to evaluate the model which shows that VIBI is faster, safer and easier to access than existing authentication models for smart-phones.
