Abstract
An object is to make it possible to add an electronic signature to an edited image under reliable environment. An imaging device includes a determination processing unit that executes determination processing for determining whether or not image data is an own device captured image captured by an own device on the basis of metadata corresponding to the image data input from outside of the own device and a signature processing unit that acquires re-signature data different from signature data at the time of imaging using the image data and metadata for the image data determined as an own device captured image by the determination processing unit.
Claims20
An imaging device comprising:
- a memory storing image data;
- and
- a camera control circuitry configured to:
- receive external metadata associated with the image data, the external metadata being external to the imaging device,
- determine whether the image data was captured by the imaging device on a basis of the external metadata, and
- responsive to determining that the image data was captured by the imaging device, acquire re-signature data using the image data and the external metadata, the re-signature data being different from signature data at a time the imaging device captured the image data.
An image data processing method comprising:
- determining, with a camera control circuitry, whether image data was captured by an imaging device on a basis of external metadata associated with the image data, the external metadata being external to the imaging device;
- and
- responsive to determining that the image data was captured by the imaging device, acquiring, with the camera control circuitry, re-signature data using the image data and the external metadata, the re-signature data being different from signature data at a time of the imaging device capturing the image data.
A non-transitory computer-readable medium comprising a program that when executed by an electronic processor, causes the electronic processor to perform a set of operations comprising:
- determining whether image data was captured by an imaging device on a basis of external metadata associated with the image data, the external metadata being external to the imaging device;
- and
- acquiring re-signature data using the image data and the external metadata, the re-signature data being different from signature data at a time of the imaging device capturing the image data.
