A method for verifying a software application to a user of a device such as a mobile phone. The device receives (102) the software application, for example a Java ME MIDIet, and checks (104) a signature associated with the software application. Where the signature is recognised, the phone indicates (108) this status to the user, for example by displaying the familiar padlock icon. The mobile phone then establishes (110) a secure code known only to the user and a trusted entity, the entity being for example the manager of the Java ME environment. The device identifies (114) the software application to the trusted entity which then checks (116) the status of the software application. If the status is verified, the entity sends (118) the status to the device; which in turn indicates (120) the secure code to the user, for example as an additional displayed number, pictogram or the like. |
