Prevention of inadvertent data synchronization to and from removable memory sources on a handheld connected device
A method is disclosed for continuously synchronizing data to and from a removable memory source connected to a user's handheld device. When the memory source is inserted into the handheld device, the device queries the memory source to determine whether the memory source is associated with the device or with an online service associated with the device. Upon determining that the memory source is associated with the device, the device exposes the memory source to the online service and allows read and write access to the online service. Upon determining that the memory source is not associated with the device, the device further checks to determine whether the user seeks to associate the memory source with the device. If the user chooses not to do so, the user is allowed to view and modify the contents of the memory source without synchronizing data to and from the online service.

a computer readable storage medium coupled to the processor, the computer readable storage medium storing instructions when executed by the processor cause the processor to:
query data stored in the removable memory source for presence of a key associated with another mobile computing device;
determine authority to access the removable memory source responsive to detecting the presence of the key associated with the other mobile computing device;
query data stored in the removable memory source for presence of a memory source identifier associated with the mobile computing device responsive to not detecting the presence of the key or determining whether the mobile computing device is authorized to access the removable memory source, the memory source identifier representing association of backup data in the removable memory source with data in the mobile computing device, the removable memory source identifier generated by the mobile computing device;
automatically synchronize the backup data in the removable memory source with data in the mobile computing device responsive to detecting the memory source identifier associated with the mobile computing device; and
access data in the removable memory source except the backup data responsive to not detecting the memory source identifier associated with the mobile computing device, and responsive to not detecting the key associated with the other mobile computing device or determining that the mobile computing device is authorized to access the removable memory source.
7. The mobile computing device of claim 6 , wherein the computer readable storage medium further stores instructions to:
determine whether the removable memory source should be associated with the mobile computing device, responsive to determining that the removable memory source is not associated with the mobile computing device; and
associate the removable memory source with the mobile computing device by registering the memory source identifier with the mobile computing device responsive to determining that the removable memory source should be associated with the mobile computing device.
8. The mobile computing device of claim 7 , wherein the instructions to determine whether the removable memory source should be associated with the mobile computing device comprises instructions to:
receive a personal identification number or a password;
determine whether the personal identification number or the password corresponds to the key.
9. The mobile computing device of claim 6 , wherein the computer readable storage medium further stores instructions to query an online service subscribed to by a user of the mobile computing device for the memory source identifier.
10. The mobile computing device of claim 6 , wherein the removable memory source comprises one of a solid state memory device or a magnetic memory device.
11. A tangible computer readable storage medium storing instructions thereon, the instructions when executed by a processor in a mobile computing device causing the processor to:
detect a removable memory source inserted into the mobile computing device;
query data stored in the removable memory source for presence of a key associated with another mobile computing device;
determine whether the mobile computing device is authorized to access the removable memory source responsive to detecting the presence of the key associated with the other mobile computing device;
query data stored in the removable memory source for presence of a memory source identifier associated with the mobile computing device responsive to not detecting the presence of the key or determining presence of the authority to access the removable memory source, the memory source identifier representing association of backup data in the removable memory source with data in the mobile computing device, the memory source identifier generated by the mobile computing device;
automatically synchronize the backup data in the removable memory source with data in the mobile computing device responsive to detecting the memory source identifier associated with the mobile computing device; and
access data in the removable memory source except the backup data responsive to not detecting the memory source identifier associated with the mobile computing device, and responsive to not detecting the key associated with the other mobile computing device or determining that the mobile computing device is authorized to access the removable memory source.
12. The computer readable storage medium of claim 11 , further comprising instructions that cause the processor to:
determine whether the removable memory source should be associated with the mobile computing device, responsive to determining that the removable memory source is not associated with the mobile computing device; and
