Abstract: To a method for accessing a service, at least one first user device executes a first application that communicates with a second user device application. The first user device sends to a remote server data relating to the first application execution, as a first user device report. The data relating to the first application execution includes information relating to either an incoming event or an outgoing event and at least one attribute relating to the first application execution. The remote server determines, based upon at least the first user device report, a trust level relating to the first user device. A third user device sends to the remote server a request for getting a trust level relating to the first user device. The remote server sends to the third user device, as a request response, the trust level relating to the first user device.

Abstract: The invention is a method of managing a package in a secure element comprising an initial operating system. The method comprises a step of updating the initial operating system to generate an updated operating system and a step of linking the package to the updated operating system. The linking step is automatically triggered by the step of updating the initial operating system.

Abstract: The invention is a method of updating a first executable code comprised in a first package in a secure element, a class instance being instantiated from said first package and comprising instance data. The method comprises the following steps: loading in the secure element an upgrade file comprising a second executable code and creating a second package from said upgrade file, changing said first executable code for said second executable code by replacing a reference to the first package by a reference to the second package in a package list stored in the secure element, while leaving the class instance alive and said instance data unchanged.

Abstract: The invention is a method of managing an object which is represented by a first instance of a class. The first instance is stored in a secure element comprising an initial operating system. The method comprises a step of updating the initial operating system to generate an updated operating system, a step of creating a metadata uniquely associated with the object, said metadata being permanently stored in the secure element and comprising a value of a parameter of said class which has been used to create said first instance. The method comprises a step of re-instantiating the object by generating an updated instance of the class in the updated operating system by using said value to set said parameter of the class, said updated instance representing the object. The re-instantiating step is automatically triggered by the step of updating the initial operating system.

Abstract: The invention relates to a method for measuring audience data. The data is broadcast and received by at least one terminal. The data is relative to at least one channel included within the broadcast data. According to the invention, the terminal determines at least one piece of configuration data relating to at least one channel consumed by a terminal user, the at least one piece of configuration data comprising a first time difference between two time references, a first time reference relating to an exit from a channel and a second time reference relating to an access to the channel. The invention relates also to corresponding terminal and token.
