Image authenticity detection method and apparatus

An image authenticity detection apparatus, comprising:

• a memory operable to store computer-readable instructions;
• and
• a processor circuitry operable to read the computer-readable instructions, the processor circuitry when executing the computer-readable instructions is configured to:
• obtain an image;
• remove low-frequency information from the image to obtain first image information of the image;
• denoise the first image information to obtain second image information;
• determine, based on a difference between the first image information and the second image information, a fixed pattern noise feature map corresponding to the image;
• analyze distribution of fixed pattern noise in the fixed pattern noise feature map, the fixed pattern noise being inherent noise from a camera sensor and not interfered by image content;
• and
• detect, based on the distribution, authenticity of the image to obtain an authenticity detection result of the image.

A non-transitory machine-readable media, having instructions stored on the machine-readable media, the instructions configured to, when executed, cause a machine to:

• obtain an image;
• remove low-frequency information from the image to obtain first image information of the image;
• denoise the first image information to obtain second image information;
• determine, based on a difference between the first image information and the second image information, a fixed pattern noise feature map corresponding to the image;
• analyze distribution of fixed pattern noise in the fixed pattern noise feature map, the fixed pattern noise being inherent noise from a camera sensor and not interfered by image content;
• and
• detect, based on the distribution, authenticity of the image to obtain an authenticity detection result of the image.
