Hawk is a security system in Rust which uses AWS services like S3, Rekognition, Lambda, etc to get the similarity score of two images sent through the Rust application. This application hits the API Gateway that invokes the AWS lambda function. The Lambda function then interacts with the AWS Rekognition with the help of the CompareFaces API and responds with a similarity score between the two images i.e the one clicked from the Raspberry Pi camera and the one being the reference image for the user stored in an S3 bucket. The similarity score will decide if the person entering the premises is the one whose RFID card is being scanned or not. If not the image stored in the S3 bucket would help us identify who was using the RFID card illegitimately. Kafka configured Rust code enables us to use the application as a simulator for the real scenario.
