Zusammenfassung:A mobile computing device has at least one processor and at least one memory together providing a first execution environment 21 and a second execution environment 22 logically isolated from the first execution environment. The following approach is taken to manage data items for an application executing the first execution environment. A trust relationship is established between a trust client 222 in the second execution environment 22 and a remote trusted party and the trust client 222 receives one or more data items from the remote trusted party. On executing the application 213 in the first execution environment 21, the trust client 222 provides the data items or further data items derived therefrom to the application 213. Provision of these data items may be conditional upon a user authentication process. A suitable mobile computing device is also described.
