Portable electronic entity i.e. universal serial bus key, for use with laptop computer, has restitution units constituting loudspeaker and display to restitute local alarm signal at electronic entity

摘要

The entity (10) has a receiving unit (14) for receiving a message (MSGi) from an external entity (100) via an universal serial bus (USB)interface. A detection unit (11) detects a fault in the message. Signal restitution units have a loudspeaker (15) and a display (16) to restitute a local alarm signal at the electronic entity that is connected to an external entity in a removable manner, where the alarm signal insists a user to disconnect the electronic entity from the external entity. The signal restitution units generate a sound signal by the loudspeaker. Independent claims are also included for the following: (1) a control method implemented by a portable electronic entity that is adapted to receive a message (2) a computer program having a set of instructions for executing a control method (3) a recording medium for storing a program for executing the control method.
