and responsive to determining that the notification counter has been decremented to zero, resetting the device. ### Claim 2 (depends on 1) The method of claim 1 wherein said reset notification includes an explanation of reason for the reset. ### Claim 3 (depends on 1) The method of claim 1 wherein the indicating comprises displaying the reset notification on a display of the device. ### Claim 4 (depends on 2) The method of claim 2 further comprising, until determining that the notification counter has been decremented to zero, displaying, on the display, an icon representative of a pending reset. ### Claim 5 (depends on 1) The method of claim 1 wherein the initializing is initiated upon detection of receipt of a set of instructions relating to privileges available to applications that reside on the device. ### Claim 6 (depends on 5) The method of claim 5 wherein the privileges relate to modification of stored cryptographic information. ### Claim 7 A device comprising: a processor capable of: initializing a notification counter to a maximum number, N, of successive instances of indicating a reset notification, N being greater than one, the reset notification including representations of reset-now and reset-later; and resetting the device upon determining that the notification counter has been decremented to zero. ### Claim 8 (depends on 7) The device of claim 7 wherein said reset notification includes an explanation of reason for the reset. ### Claim 9 (depends on 7) The device of claim 7 wherein the indicating comprises displaying the reset notification on a display of the device. ### Claim 10 (depends on 9) The device of claim 9 wherein the processor is further capable of displaying, on the display, an icon representative of a pending reset, until determining that the notification counter has been decremented to zero. ### Claim 11 (depends on 7) The device of claim 7 wherein the processor is further capable of initiating the initializing upon detection of receipt of a set of instructions relating to privileges available to applications that reside on the device. ### Claim 12 (depends on 11) The device of claim 11 wherein the privileges relate to modification of stored cryptographic information. ### Claim 13 A non-transitory digital storage medium containing a computer program configured to, when executed by a device including a processor, cause the processor to: initialize a notification counter to a maximum number, N, of successive instances of indicating a reset notification, N being greater than one, the reset notification including representations of reset-now and reset-later; and reset the device responsive to determining that the notification counter has been decremented to zero. ### Claim 14 (depends on 13) The non-transitory digital storage medium of claim 13 wherein said reset notification includes an explanation of reason for the reset. ### Claim 15 (depends on 13) The non-transitory digital storage medium of claim 13 wherein the indicating comprises displaying the reset notification on a display of the device. ### Claim 16 (depends on 15) The non-transitory digital storage medium of claim 15 further comprising, until determining that the notification counter has been decremented to zero, displaying, on the display, an icon representative of a pending reset. ### Claim 17 (depends on 13) The non-transitory digital storage medium of claim 13 wherein the initializing is initiated upon detection of receipt of a set of instructions relating to privileges available to applications that reside on the device. ### Claim 18 (depends on 17) The non-transitory digital storage medium of claim 17 wherein the privileges relate to modification of stored cryptographic information. ### Claim 19 A method for causing reset of a device, the method comprising: detecting initiation of a reset process; controlling indication of a reset notification, the reset notification including a representation that the device will be reset responsive to detection of a trigger event; until determining that a notification counter has been decremented to zero, displaying, on a display, an icon representative of a pending reset; and responsive to detecting the trigger event, resetting the device. ### Claim 20 (depends on 19) The method of claim 19 wherein the detecting the initiation of the reset process comprises at least one of: receiving a reset command; detecting that code needs to be installed; receiving an encryption key; receiving owner control information; or detecting receipt of a set of instructions relating to privileges available to applications that reside on the device. ### Claim 21 (depends on 20) The method of claim 20 wherein the privileges relate to modification of stored cryptographic information. ### Claim 22 (depends on 19) The method of claim 19 wherein the detecting of the trigger event comprises detecting an expiration of an indicated time period. ### Claim 23 (depends on 19) The method of claim 19 wherein the detecting of the trigger event comprises detecting the device entering a locked state. ### Claim 24 (depends on 19) The method of claim 19 wherein said reset notification includes an explanation of reason for the reset. ### Claim 25 (depends on 19) The method of claim 19 wherein the representation comprises displaying the reset notification on the display of the device. ### Claim 26 A device comprising: a processor capable of: detect initiation of a reset process; control indication of a reset notification, the reset notification including a representation that the device will be reset responsive to detection of a trigger event; until determining that a notification counter has been decremented to zero, display, on a display, an icon representative of a pending reset; and reset of the device responsive to detecting the trigger event. ### Claim 27 A non-transitory digital storage medium containing a computer program configured to, when executed by a device including a processor, cause the processor to: detect initiation of a reset process; control indication of a reset notification, the reset notification including a representation that the device will be reset responsive to detection of a trigger event; until determining that a notification counter has been decremented to zero, display, on a display, an icon representative of a pending reset; and reset of the device responsive to detecting the trigger event.
