Abstract
This paper reviews few important and contemporary research contributions in the field of sign language biometrics, especially Indian sign language (ISL) biometrics. The current research study suggests that the work in this area is very limited in Indian context and therefore we have reviewed the existing work on ISL or similar biometrics for different languages. The scope of potential research in ISL biometrics is development of databases since there is no standard database for ISL biometrics. The paper recommends the directions and viable method that could lead to a robust biometrics which would be very useful communication means for hearing and speech impaired people. A database was created as sample and tested using a standard method, scale invariant feature transform (SIFT) method and found that the database worked in ISL biometric system. The suggestions and anticipations of a organization working for deaf and dumb people have also been studied.
