Hardware verification with RFID-stored build information

1. A method, comprising:

interrogating a radio-frequency identification (RFID) tag in a mobile device to obtain build information for hardware verification of one or more hardware components in the mobile device;

identifying current information for each of the one or more hardware components;

determining, for each of the one or more hardware components, whether the current information matches the build information based on a vendor identifier (ID) associated with each of the one or more hardware components and included in the current information and the build information;

responsive to the determination that the current information does not match the build information, displaying a message indicating that at least one of the one or more hardware components does not match the build information and storing, in a memory of the RFID tag, the current information that does not match the build information for each of the one or more hardware components before an operating system is loaded; and

loading the operating system for restricted functionality in the mobile device.

2. The method as recited in claim 1 , further comprising:

executing a bootloader that performs the interrogating, the identifying, and the determining; and

responsive to the determination that the current information does match the build information, loading the operating system for unrestricted functionality in the mobile device.

3. The method as recited in claim 1 , wherein the current information and the build information includes the vendor identifier (ID) and a model ID for each of the one or more hardware components.

4. The method as recited in claim 1 , wherein the build information corresponds to when the one or more hardware components are installed during manufacture and assembly of the mobile device.

5. The method as recited in claim 1 , further comprising:

encrypting the build information prior to storing the build information in the RFID tag; and

decrypting the build information to determine whether the current information matches the build information.

6. The method as recited in claim 1 , wherein said identifying the current information comprises interrogating each of the one or more hardware components to obtain the current information.

7. The method as recited in claim 1 , wherein responsive to the determination that the current information does not match the build information, the method further comprising limiting functionality of at least the one or more hardware components.

8. A mobile device, comprising:

one or more hardware components;

a radio-frequency identification (RFID) tag to store configuration information of the mobile device for hardware verification, the configuration information including build information for each of the one or more hardware components in the mobile device;

a memory and processing system to implement a bootloader to:

identify current information for each of the one or more hardware components;

determine, for each of the one or more hardware components, whether the current information matches the build information based on a vendor identifier (ID) associated with each of the one or more hardware components and included in the current information and the build information;

responsive to the determination that the current information does not match the build information, initiate display of a message that indicates at least one of the one or more hardware components does not match the build information and store the current information in a memory of the RFID tag for the at least one of the one or more hardware components before an operating system is loaded; and

load the operating system for restricted functionality in the mobile device.

9. The mobile device as recited in claim 8 , wherein, responsive to the determination that the current information does not match the build information, the bootloader limits functionality of the one or more hardware components.

10. The mobile device as recited in claim 8 , wherein the current information and the build information includes the vendor identifier (ID) and a model ID for each of the one or more hardware components.

11. The mobile device as recited in claim 8 , wherein the build information corresponds to when the one or more hardware components are installed during manufacture and assembly of the mobile device.

12. The mobile device as recited in claim 8 , wherein the build information is encrypted prior to being stored in the RFID tag, and the bootloader decrypts the build information to determine whether the current information matches the build information.

13. The mobile device as recited in claim 8 , wherein the bootloader interrogates each of the one or more hardware components to identify the current information.

14. The mobile device as recited in claim 8 , wherein, responsive to the determination that the current information does match the build information, the bootloader loads the operating system for unrestricted functionality in the mobile device.

15. A system, comprising:

a radio-frequency identification (RFID) tag to store build information for hardware verification of a hardware component installed in a device during manufacture;

a bootloader that is executable in the device to:

obtain current information corresponding to the hardware component;

determine whether the current information matches the build information of the hardware component based on a vendor identifier (ID) associated with the hardware component and included in the current information and the build information;

responsive to a determination that the current information does not match the build information, store the current information that does not match the build information for the hardware component in a memory of the RFID tag before an operating system is loaded; and

load the operating system for restricted functionality.

16. The system as recited in claim 15 , wherein, responsive to the determination that the current information does not match the build information, the bootloader initiates to display of a message that indicates the hardware component does not match the build information.

17. The system as recited in claim 15 , wherein the bootloader, responsive to a determination that the current information does match the build information, loads the operating system for unrestricted functionality in the mobile device.

18. The system as recited in claim 15 , wherein the build information and the current information corresponding to the hardware component includes the vendor identifier (ID) and a model ID.

19. The system as recited in claim 15 , wherein the build information is encrypted prior to being stored in the memory of the RFID tag, and the bootloader decrypts the build information prior to the determination of whether the current information matches the build information of the hardware component.

20. The system as recited in claim 15 , wherein the hardware component is device memory and the bootloader, responsive to the determination that the current information does not match the build information, limits access to the device memory.
