Method for the execution and processing of data, corresponding device and computer program

Method for executing a user application within a server, the method comprising:

• a step of reception, from a trusted environment of a communications terminal, of a request for executing said user application;
• a step for obtaining at least one piece of data needed for executing said user application as a function of at least one piece of data of the request for executing said user application and a source of complementary data;
• a step of instantiation of said user application, activating the execution of said user application;
• a step for obtaining a video stream coming from the execution of said user application;
• and
• a step of transmission, to said trusted environment of said communications terminal, of said video stream.

Communications terminal of the type comprising a trusted environment, said trusted environment comprising a secured storage space and a secured applications executing module, the terminal being capable of executing at least one application within said trusted environment, said terminal comprising:

• means for receiving, within the trusted environment, an instruction for launching a user application;
• means for transmitting a request for executing said user application to a server;
• means for receiving, from the server, by a video-rendering application executed within the trusted environment, a video stream resulting from the execution, on the server, of said user application;
• and
• means for displaying said video stream on a screen of said communications terminal, accessible from said trusted environment.

Server for the execution of a user application characterized in that it comprises:

• means for receiving, from a trusted environment of a communications terminal, a request for executing said user application;
• means for obtaining at least one piece of data needed for executing said user application as a function of at least one piece of data of the request and a source of complementary data;
• means for instantiating said user application, activating the execution of said user application;
• means for obtaining a video stream coming from the execution of said user application;
• and
• means for transmitting, to said trusted environment of said communications terminal, of said video stream.
