Method for detecting that a secure element has been temporarily disconnected from a device, and corresponding device

A method for detecting at the level of a first device and at the level of a MNO server that a removable secure element has been temporarily disconnected from said first device with which said removable element is cooperating, said first device entering during a lap of time in a sleeping mode, said method comprising:

• A—Providing by said secure element to said first device a Temporal Global Identity, called first Temporal Global Identity, on demand by said first device, before said first device enters in said sleeping mode and storing said first Temporal Global Identity in a memory of said first device;
• B—Entering said first device in said sleeping mode;
• C—If said secure element is inserted and used by a second device during the sleeping mode of said first device, said use consisting in an action different from a reading of said first Temporal Global Identity, replacing in said secure element said first Temporal Global Identity by a second Temporal Global Identity different from said first Temporal Global Identity, providing said second Temporal Global Identity to said second device and storing said second Temporal Global Identity in a memory of said second device;
• D—When getting out from said sleeping mode by said first device, reading by said first device the Temporal Global Identity stored in said secure element;
• E—If the Temporal Global Identity read at step -D- is not the same than the Temporal Global Identity stored at step -A-, sending by said first device to said MNO server a message in order to inform him that said secure element has been used by another device.
