Identification of human, based on dental records is one of the popular and emerging trends in Biometrics. An efficient technique to identify human based on their dental records using bag of features and multi-class Support Vector machine proposed in this paper. The dental images of 34 persons were collected using digital camera. The captured images were pre-processed, and SURF bag of features were extracted using image processing. The extracted SURF features are used to design Multi-class Support Vector Machine for human identification. The accuracy for human identification using dental features of proposed model is 98.85 percent for training data and 97.95 percent for testing data.
