How to Spot Deepfakes in Calls and Videos: Tips to Stay Ahead

Deepfake technology is advancing rapidly, making it increasingly difficult to distinguish real videos and calls from fake ones. These synthetic media use artificial intelligence to create highly realistic but fabricated content. As deepfakes become more sophisticated, it is crucial to learn how to spot them to protect yourself from misinformation, fraud, and manipulation.

Understanding the Rise of Deepfakes and Why They Matter

Deepfakes started as a niche technology but have now become a mainstream concern. They can be used for harmless entertainment, but also for malicious purposes such as identity theft, political manipulation, and scams. The challenge is that deepfakes are no longer easy to detect with the naked eye.

For example, a deepfake video might show a public figure saying something they never actually said, or a scammer might impersonate a CEO’s voice during a business call to authorize fraudulent transactions. The consequences can be severe, so knowing how to identify deepfakes is essential.

Key Signs to Look for When Spotting Deepfakes in Videos and Calls

Here are some practical pointers to help you spot deepfakes during video calls or when watching videos:

1. Look for Unnatural Facial Movements and Expressions

Deepfake algorithms sometimes struggle with subtle facial cues. Watch for:

• Inconsistent blinking: People blink naturally and regularly. Deepfakes may have irregular or no blinking.

• Unnatural smiles or lip movements: The mouth might not sync perfectly with speech or show odd shapes.

• Stiff or jerky head movements: Real human motion is fluid; deepfakes can appear robotic or too smooth.

  
  

2. Pay Attention to Lighting and Shadows

Lighting inconsistencies are a common giveaway:

• Mismatched shadows: Shadows on the face or background may not align with the light source.

• Uneven skin tone: Look for patches of skin that seem too smooth or oddly colored.

• Glitches around hairlines or edges: Hair can be difficult to render realistically, leading to blurry or flickering edges.

  
  

3. Listen Closely to the Audio Quality and Speech Patterns

Audio can reveal deepfakes, especially in calls:

• Robotic or unnatural voice tone: AI-generated voices may lack emotional nuance or sound synthetic.

• Odd pauses or unnatural pacing: Speech might have strange hesitations or speed changes.

• Mismatch between lip movement and audio: If the mouth doesn’t sync with the words, it’s suspicious.

Tools and Techniques to Verify Authenticity of Videos and Calls

Technology can help you verify if a video or call is genuine. Here are some methods and tools:

1. Use Deepfake Detection Software

Several AI-powered tools analyze videos for signs of manipulation. Examples include:

• Microsoft Video Authenticator: Detects deepfake content by analyzing pixels and subtle artifacts.

• Deepware Scanner: A mobile app that scans videos for deepfake indicators.

  
  

2. Check Metadata and Source Information

• Verify the video’s origin: Look for the original source or official channels.

• Inspect metadata: Metadata can reveal if a file has been edited or altered.

• Reverse image search: Use tools like Google Reverse Image Search to find if the video or frames have appeared elsewhere.

  
  

3. Cross-Verify with Trusted Sources

If a video or call seems suspicious, check:

• Official statements: Confirm with credible news outlets or official social media accounts.

• Multiple sources: Authentic events are usually reported by several independent sources.

  
  

Practical Tips to Protect Yourself from Deepfake Scams

Deepfakes are often used in scams, especially in business or personal finance contexts. Here’s how to stay safe:

• Be skeptical of unexpected requests: If a video call or message asks for sensitive information or money, verify through a separate channel.

• Use multi-factor authentication: Protect accounts with additional security layers.

• Educate your team or family: Awareness is key to preventing deepfake fraud.

• Report suspicious content: Notify platforms or authorities if you encounter potential deepfakes.
