Abstract: A method of providing security by personalizing a computer application having executable instructions, the method comprising the steps of installing a modified application on a user computer in which a plurality of groups of instructions needed for complete operation of the application are missing and are replaced by link portions suitable for causing the missing groups of instructions to be executed when said missing groups of instructions are installed in a remote server or in a communication member itself installed on the user computer, in sharing the missing groups of instructions between the communication member and the remote server, and in establishing a link between the communication member and the remote server.

Abstract: The invention relates to a personalized communications method associated with various computer applications, and to a corresponding program product. The method comprises the steps of: associating the various applications with a common interface adapted to be configured to contain identity data for the common interface, in verifying during installation of each application on the computer whether the common interface is already present, in automatically linking the application with the common interface when the common interface is already installed, in establishing a connection between the common interface and a server on launching an application, and in transmitting to the server at least part of the identity data of the common interface.
