<p>To check a secure registration to a service provided by a web server from a communication terminal (TC), the web server (SW) saves a dynamically generated code matching the terminal (TC)'s IP address and transmits a message containing the code (CodC) to an e-mail address. This address is provided by the user in response to the terminal's connection to the web server. The server transmits to the terminal an application (App) capable of generating an automated test in order to tell computers apart from humans. The answer provided by the user is encrypted with the terminal's IP address and the code contained in the message transmitted to the e-mail address, and is directly transmitted by the application to the server, which decrypts it and compares it with an expected answer in order to enable access to the Web server if the decrypted answer matches the expected answer.</p> |
