Abstract
Provided is a data processing apparatus including: a storage unit that stores a first operating system (OS), a first application program executed after the first OS, a second OS, and a second application program executed after the second OS; and at least one processor configured to, in a first activation mode, verify the first OS, execute the first OS, and then execute the first application program, and, in a second activation mode, verify the second OS, execute the second OS, and then execute the second application program, in which the at least one processor is further configured to restore the first OS, in a case where it is determined on the verification of the first OS that the first OS is not valid, with use of the second OS.
Claims11
A data processing apparatus comprising:
- a storage unit that stores a first operating system (OS), a first application program executed after the first OS is executed, a second OS, and a second application program executed after the second OS is executed;
- and
- at least one processor configured to, in a first activation mode, verify the first OS, execute the verified first OS, and then execute the first application program, and, in a second activation mode, verify the second OS, execute the verified second OS, and then execute the second application program,
- wherein the at least one processor is further configured to restore, in a case where it is determined on the verification of the first OS that the first OS is not valid, the first OS with use of the second OS.
An image processing apparatus that processes an image, comprising:
- a first verification unit configured to verify validity of a common part that is included in firmware to be activated among a plurality of pieces of firmware;
- and
- a restoration unit configured to restore, in a case where the common part that is included in the firmware to be activated is verified as not being valid by the first verification unit, the common part that is included in the firmware to be activated, with use of a common part that is included in firmware not to be activated among the plurality of pieces of firmware.
An information processing method executed by an image processing apparatus that processes an image, the method comprising:
- verifying validity of a common part that is included in firmware to be activated among a plurality of pieces of firmware;
- and
- restoring, in a case where the common part that is included in the firmware to be activated is verified as not being valid by the verifying, the common part that is included in the firmware to be activated, with use of a common part that is included in firmware not to be activated among the plurality of pieces of firmware.
