Which artifact is commonly seen in GAN-generated images and can indicate AI generation?
Odd number of fingers
High dynamic range
Lens flare
Perfect symmetry
GANs often struggle to render human appendages correctly, resulting in odd numbers or malformed fingers. Other options like lens flare or high dynamic range are unrelated to AI-specific artifacts.
Which metadata field is most useful for quickly checking when an image was originally created?
Pixel Histogram
Compression Ratio
EXIF Creation Date
Color Saturation Value
The EXIF Creation Date field directly records when a camera or software generated the image. Other options do not provide timestamp information.
Which basic image forgery technique involves duplicating parts of an image to conceal unwanted elements?
Deepfake face swap
GAN synthesis
Blockchain certification
Clone stamping
Clone stamping is a common manual editing technique where regions are duplicated to hide or remove parts of an image. Deepfake face swap and GAN synthesis are more advanced, and blockchain is unrelated.
Which tool can help authenticate an image by finding instances of it across the web?
Vector drawing editor
3D modeling software
Reverse image search
Audio spectrogram analyzer
Reverse image search services match an image against web databases to find duplicates or source occurrences, aiding authenticity checks. Other tools are unrelated to web-based verification.
Which ethical practice should you follow when verifying an image of a person?
Assume public domain status
Publish metadata publicly
Share findings without verification
Obtain consent before analysis
Obtaining consent respects privacy and personal rights. Other options ignore ethical considerations or risk unauthorized disclosure.
If an image's shadow directions are inconsistent between objects, what does this likely indicate?
Video compression artifact
High dynamic range processing
Possible tampering
Natural lighting
Inconsistent shadows suggest objects were composited under different lighting, indicating manipulation. HDR processing or compression do not cause directional mismatches.
Which EXIF tag often reveals which software was used to edit an image?
XResolution
Software
GPSLatitude
Make
The Software tag in EXIF metadata typically records the application used to save or edit an image. GPS and camera make tags serve other purposes.
What irregular behavior in deepfake videos is a clue to their inauthenticity?
Accurate subtitles
Perfect background audio
Unnatural eye blinking patterns
Stable frame rate
Deepfake algorithms sometimes fail to model natural blinking, resulting in unnatural eye movements. The other options are not distinctive deepfake flaws.
Error Level Analysis (ELA) helps identify image forgeries by showing areas that have been what?
Blurred smoothly
Converted to grayscale
Blurred randomly
Recompressed at different levels
ELA highlights regions with different compression patterns, which often coincide with editing. Grayscale conversion or random blur do not produce ELA differences.
Which noise-based method can link a photo to the specific camera sensor that captured it?
Gaussian blur detection
Color histogram matching
Photo Response Non-Uniformity (PRNU) analysis
Edge detection
PRNU leverages subtle sensor noise patterns unique to each camera. Other techniques do not identify sensor-specific noise.
Which file format is ideal for preserving image data and metadata without compression loss?
JPEG
TIFF
PNG
GIF
TIFF supports lossless storage and retains detailed metadata. JPEG and GIF apply lossy compression; PNG is lossless but has limited metadata support compared to TIFF.
Detecting subtle periodic artifacts introduced by GAN upsampling is best done using which analysis?
Edge orientation distribution
Frequency-domain analysis
Color saturation histogram
Pixel intensity thresholding
GAN upsampling often leaves traces in the frequency domain, detectable via spectral analysis. Other methods focus on color or edges but miss periodic artifacts.
A robust digital watermark used for authentication should be which of the following?
Visible and easily cropped
Imperceptible yet hard to remove
Stored only in EXIF metadata
Encrypted with a single-use key
An effective watermark is hidden from casual view but remains intact under typical edits. Visible marks are removable, and metadata or single-use keys alone do not ensure robustness.
Which image forgery technique involves stretching, skewing, or warping elements to blend seams?
Histogram equalization
Geometric transformation
Vector tracing
Color grading
Geometric transformation warps image elements so seams from splicing appear natural. The other options deal with color or vector data, not spatial blending.
What ethical risk arises when image authentication algorithms underperform on certain demographic groups?
Reduced computational efficiency
Higher storage requirements
Increased compression artifacts
Algorithmic bias leading to unfair scrutiny
If detectors misclassify images of some groups, they risk unfairly targeting or mistrusting those individuals. The other issues relate to technical performance, not ethics.
A challenge in designing neural deepfake detectors is ensuring they generalize across which dimension?
Various display resolutions
Different GAN architectures
Diverse camera lens types
Multiple user interfaces
Deepfake detectors must handle new and varied GAN architectures to remain effective. Display resolution or UI differences do not fundamentally change generation patterns.
Combining metadata and pixel-level anomaly detection enhances authenticity checks by doing what?
Automating color correction
Minimizing file size
Increasing compression ratio
Correlating independent clues for stronger evidence
By cross-validating metadata inconsistencies with pixel artifacts, analysts can build a more reliable case. File size or color correction are unrelated benefits.
Which pattern is characteristic of upsampling artifacts produced by convolutional networks?
Checkerboard grid artifacts
Radial blur
Uniform noise spots
Circular banding
Checkerboard artifacts stem from uneven overlap in deconvolution or upsampling layers. Other patterns do not specifically indicate neural upsampling.
What approach involves embedding an imperceptible but verifiable code inside an image to deter tampering?
JPEG recompression
Vector quantization
Adversarial watermarking
HDR merging
Adversarial watermarking hides a resilient code within pixel values that reveals tampering. JPEG recompression and other options do not provide intrinsic authenticity codes.
Which ethical principle is critical when deploying automated image authentication at scale?
Unlimited data retention
Maximizing algorithm complexity
Data minimization and privacy protection
Universal public sharing
Automated systems must minimize personal data collection to respect user privacy. Complexity or unrestricted sharing does not address ethical deployment.
