IDENTIFYING DEEPFAKE AUDIO AND VIDEO
There are several indicators and tools that can help determine deepfakes.
1. Visual Inconsistencies
Deepfake videos often exhibit subtle visual anomalies that distinguish them from authentic videos. These include unnatural eye movements, inconsistent lighting and shadows, blurred or distorted facial features, and irregular blinking patterns. When someone is speaking, watch the muscles in the face and mouth to make sure they match the words. Look for sudden, jerky or unnatural motion. Closely scrutinize videos for these signs, especially in important or high-stakes scenarios where authenticity is critical.
2. Audio Irregularities
Like deepfake videos, deepfake audio often has inconsistencies. Common red flags include unnatural pauses, irregular speech patterns and background noise inconsistencies. These irregularities may be very subtle and undetectable by ear. Using specialized software to analyze audio spectrograms can help identify these anomalies.
3. Deepfake Detection Tools
Several tech solutions have been developed to assist in identifying deepfakes. These tools employ artificial intelligence (AI) and machine learning to analyze content and attempt to identify its authenticity. Using deepfake detection tools can aid in verifying authenticity, but they are not 100% accurate. Some detectors are better than others in validating authenticity depending on the type of deepfake content they are analyzing, so using multiple tools is recommended when assessing critical content.
4. Cross-Checking Content
In many cases, authentic content has a digital footprint that can be referenced to help validate its authenticity. If a video or audio clip is questionable, do an internet search to see if that content is already online. You may find social media posts, blogs or articles referencing the content as authentic or fake.
PROTECTING LAW FIRMS AND STAFF
The most important means to keep firms safe are creating policies and educating staff. Here are specific steps to help protect yourself:
1. Create a policy.
Coming up with a firmwide policy lets staff know the importance of combating deepfakes and specifically how to act to keep the firm and its clients safe. A good policy should include particular scenarios where deepfake attacks are likely, such as money transfers, purchases and requests for information, as well as explicit steps employees should take to validate the authenticity of the request before acting. Consider expanding existing cybersecurity policies to include deepfake detection.
2. Establish clear verification procedures.
Develop simple and straightforward procedures for verifying the authenticity of audio and video content and include these in the policy. Establish protocols for cross-referencing information, consulting multiple sources and using technological tools to analyze content. Define an escalation process for when someone has identified a potential attack, covering what to do and which people to notify.
3. Educate staff.
A policy alone won’t keep you safe. Educate staff about the risks and indicators of deepfake technology. Train them on the common scenarios and actions to take. A good training plan should include practical exercises and real-world examples to reinforce learning. Conduct regular training sessions to raise awareness and equip employees with the knowledge and skills needed to identify and respond to deepfakes.
4. Test your staff.
Build on your training foundation with regular deepfake testing. Consider engaging a professional organization to test your staff by initiating safe, harmless deepfake attacks and gauge their adherence to policy and training. If any of your staff fall prey to these attacks, provide them with additional training to reinforce the right behavior.
5. Collaborate with cybersecurity experts.
Partnering with cybersecurity experts can provide valuable insights and support in defending against deepfake threats. These experts can assist in developing and implementing advanced detection and mitigation strategies, as well as furnishing ongoing monitoring and threat assessment services.
6. Keep abreast of technological advancements.
Deepfake technology is evolving and improving at a rapid pace. Staying informed about the latest developments is essential for maintaining effective defenses. Law firm administrators should regularly review industry publications, attend relevant conferences and workshops and participate in professional networks to keep up to date on emerging trends and best practices.
By understanding how to identify deepfake audio and video and implementing comprehensive protective measures, law firm administrators can safeguard their firms and staff from these digital deceptions. Through vigilance, education and collaboration, law firms can stay ahead of these threats and maintain the integrity and trust essential to their practice.
