It is apparent that the crimes are increasing day by day in all the states in this India. We propose Face Detection and Comparison using Combinational Deep Learning Techniques as an application that is used to aid the identification of existing criminals and alert a potential criminal activity. This detector can be used in all kinds of public places like malls, cinema theatres and any crowded areas. The cameras in public places detect the faces, The system uses a combination of two methods; face recognition and verification and it also includes sentiment analysis to identify new criminals who have not been registered in the police records by scanning the public reactions such as fear and anxiety. The face recognition is performed on acquired images, then it verifies that face using a face classification method that uses Convolution Neural Network which is integrated in the system. The system which is tested does the accurate performance to recognize the face within the requirement limits. After recognizing the face, it verifies that face through a criminal database. Or if the model identifies any suspicious features and activities, it notifies the police mentioning prospective suspect. If the criminal is spotted then the police will receive an alert in the control room like “criminal spotted” then control room operators send the information to the nearest police to catch him. The police will receive the clear photo of that criminal, the location where he was spotted and information of his crime.
