System and method for accessing and updating secured data
View Patent ↗A method is provided for use on an electronic device having a display, a communication component, a memory, and a processor coupled to the display, the communication component, and the memory. The memory stores data in a first sandbox and data in a second sandbox, the first sandbox being a secure sandbox and having a shadow data component, the shadow data component storing a subset of the data stored in the first sandbox. The method comprises, in response to a request, providing the data stored in the first sandbox when the first sandbox is in an unlocked mode and providing the data stored in the shadow data component when the first sandbox is in a locked mode.
1. An electronic device comprising:
a display;
a communication component;
a memory storing first data in a first sandbox and second data in a second sandbox, the first sandbox being a secure sandbox and having a shadow data component, the shadow data component storing a subset of the first data stored in the first sandbox; and
a processor coupled to the display, the communication component, and the memory, the processor being configured to:
in response to a request:
provide the first data stored in the first sandbox when the first sandbox is in an unlocked mode; and
provide the first data stored in the shadow data component when the first sandbox is in a locked mode.
2. The electronic device according to claim 1 , wherein the processor is further configured to:
receive from a server via the communication component information for updating the first data stored in the first sandbox;
update the first data stored in the first sandbox when the first sandbox is in the unlocked mode; and
update the first data stored in the shadow component.
3. The electronic device according to claim 1 , wherein the first sandbox further has an associated queue and the processor is further configured to:
receive from a server via the communication component information for updating the first data stored in the first sandbox;
store the information for updating the first data stored in the first sandbox in the queue when the first sandbox is in the locked mode; and
update the first data stored in the shadow data component.
4. The electronic device according to claim 3 , wherein the processor is further configured to:
update the first data stored in the first sandbox based on the information for updating the first data stored in the first sandbox stored in the queue when the first sandbox enters the unlocked mode.
5. The electronic device according to claim 1 , wherein both the first sandbox and the second sandbox are controlled exclusively by a single operating system, the first data stored in the first sandbox is encrypted, and the first data stored in the shadow data component is a redundant subset of the first data stored in the first sandbox.
6. The electronic device according to claim 1 , wherein the electronic device displays an update on the display using the first data stored in the shadow data component when the first sandbox is in the locked mode.
7. The electronic device according to claim 6 , wherein the update is selected from the group consisting of a calendar reminder, an email notification, and a contact list entry.
8. The electronic device according to claim 3 , wherein an element of the first data that is stored in both the first sandbox and the shadow data component is associated by a first identifier and an element of the first data that is stored in both the queue and the shadow data component is associated by a second identifier.
9. The electronic device according to claim 1 , wherein when the first sandbox is in the locked mode, all of the first data stored in the first sandbox is inaccessible except for first data stored in a start-up area of the first sandbox until access to the first sandbox is authenticated and wherein the shadow data component is stored in the start-up area.
10. A method for use on an electronic device having a display, a communication component, a memory storing first data in a first sandbox and second data in a second sandbox, the first sandbox being a secure sandbox and having a shadow data component, the shadow data component storing a subset of the first data stored in the first sandbox, and a processor coupled to the display, the communication component, and the memory, the method comprising:
in response to a request:
providing the first data stored in the first sandbox when the first sandbox is in an unlocked mode; and
providing the first data stored in the shadow data component when the first sandbox is in a locked mode.
11. The method according to claim 10 , further comprising:
receiving from a server via the communication component information for updating the first data stored in the first sandbox;
updating the first data stored in the first sandbox when the first sandbox is in the unlocked mode; and
updating the first data stored in the shadow component.
12. The method according to claim 10 , wherein the first sandbox further has an associated queue, the method further comprising:
receiving from a server via the communication component information for updating the first data stored in the first sandbox;
storing the information for updating the first data stored in the first sandbox in the queue when the first sandbox is in the locked mode; and
updating the first data stored in the shadow data component.
13. The method according to claim 12 , further comprising:
updating the first data stored in the first sandbox based on the information for updating the first data stored in the first sandbox stored in the queue when the first sandbox enters the unlocked mode.
14. The method according to claim 10 , wherein both the first sandbox and the second sandbox are controlled exclusively by a single operating system, the first data stored in the first sandbox is encrypted, and the first data stored in the shadow data component is a redundant subset of the first data stored in the first sandbox.
15. The method according to claim 10 , further comprising displaying an update on the display using the first data stored in the shadow data component when the first sandbox is in the locked mode.
16. The method according to claim 15 , wherein the update is selected from the group consisting of a calendar reminder, an email notification, and a contact list entry.
17. The method according to claim 12 , wherein an element of first data that is stored in both the first sandbox and the shadow data component is associated by a first identifier and an element of first data that is stored in both the queue and the shadow data component is associated by a second identifier.
18. The method according to claim 10 , wherein when the first sandbox is in the locked mode, all of the first data stored in the first sandbox is inaccessible except for first data stored in a start-up area of the first sandbox until access to the first sandbox is authenticated and wherein the shadow data component is stored in the start-up area.
19. A computer program product comprising a non-transitory computer readable medium having stored thereon computer executable instructions that when executed by a computer perform a method for use on the computer having a display, a communication component, a memory storing first data in a first sandbox and second data in a second sandbox, the first sandbox being a secure sandbox and having a shadow data component, the shadow data component storing a subset of the first data stored in the first sandbox, and a processor coupled to the display, the communication component, and the memory, the method comprising:
in response to a request:
providing the first data stored in the first sandbox when the first sandbox is in an unlocked mode; and
providing the first data stored in the shadow data component when the first sandbox is in a locked mode.
