An analyst is verifying an audio recording that allegedly captures a conversation between two individuals. The analyst notices that the background noise in the recording is inconsistent with the claimed location. What should the analyst do to verify the recording?

Compare the background noise with known recordings from the claimed location.

Use an AI voice recognition tool to identify the speakers.

Check the audio's metadata to see if it was recorded on a specific device.

Analyze the audio's file size to determine if it was compressed.

An analyst is verifying a photo that appears to show a government building at night. The image metadata shows a GPS coordinate that places the location in a residential area. The analyst runs a reverse image search and finds the same image on a stock photo site, dated two years earlier. What is the most appropriate conclusion?

The image is likely a stock photo reused with false context; the GPS metadata may have been stripped or altered.

The image is a deepfake generated by AI because the metadata is inconsistent.

The image is authentic because reverse image search only finds copies, not originals.

The image is authentic but the GPS coordinate is inaccurate due to camera error.

An analyst receives an audio file and wants to verify its authenticity. Which technique involves checking the file's embedded information such as recording device, software, and timestamps?

Cross-referencing with known sources

An analyst is verifying an image that appears to show a protest. The image metadata shows it was taken with a specific camera model. The analyst also has an audio recording that supposedly captures the same protest. What is the most appropriate way to corroborate the image and audio?

Compare the time and location metadata of the image with the audio recording's metadata.

Use reverse image search on the audio recording.

Analyze the audio's spectral content to see if it matches the image's colors.

Check the image's file size against the audio's file size.
