Survey on Restful Web Services Using Open Authorization (Oauth)
Web services are Application based Programming Interfaces (APIs) or web APIs that are accessed through Hyper Text Transfer Protocol (HTTP) to execute on a remote system hosting the requested services. A restful web service is a budding technology, and a light weight approach that do not restrict the client-server communication. The Open Authorization (OAuth) 2.0 protocol enables the users to grant third-party application access to their web resources without sharing their login credential data. The authorization server includes authorization information with the access token and signs the access token.
