In today’s digital age, artificial intelligence (AI) is transforming industries worldwide including the field of private investigations (PI). Investigators who embrace AI can process vast amounts of data faster, enhance surveillance techniques, and uncover hidden patterns that were previously difficult to detect. But how exactly does AI fit into the world of private detectives? Let’s take a look at how AI is changing the world of investigations.
AI-Driven Data Analysis & OSINT (Open-Source Intelligence)
This is one of the most exciting developments in private investigations. Modern investigators rely on open-source intelligence (OSINT) to gather crucial information from public records, social media, geolocation OSINT, and online sources.
OSINT is advancing so quickly and has such a wide range of applications that it definitely deserves its own blog post. The most basic explanation sourced by Google is that OSINT "is the practice of collecting and analyzing publicly available information to gain actionable intelligence, used by cybersecurity professionals, law enforcement, and others to assess threats and make informed decisions." However, private entities such as law firms and private investigators are among the largest consumers of this service.
Enhanced Surveillance & Monitoring
Enhanced surveillance and monitoring involves using advanced technologies to improve the effectiveness and scope of traditional surveillance methods. These tools combine to offer a more comprehensive, efficient, and scalable approach to monitoring people, locations, or activities for private investigations or security purposes. This can include:
AI-powered facial recognition: Identifying individuals in crowds or through video footage to track movements and verify identities.
License plate recognition (LPR): Scanning and tracking vehicles through automated systems, often used in conjunction with traffic cameras and/or cameras on public transportation or tolls. While LPR data is not collected in real time, it may reveal patterns and locations where a tag was logged.
Motion detection: Using sensors or cameras that trigger alerts when unusual activity occurs, providing more efficient monitoring.
Drones: Offering a broader view for surveillance, especially in hard-to-reach or large areas, often equipped with cameras and tracking technology.
Real-time data analysis: Using AI to analyze patterns in live video feeds, such as identifying unusual behavior or linking multiple sources of data (e.g., social media, GPS, or surveillance cameras).
Advanced video analytics: Enhancing low-quality footage to extract clearer images for facial recognition or object detection, improving evidence gathering. The ability to enhance low-quality videos for better facial recognition and object detection is advancing rapidly. Today, applications that produce impressive results are even available for download on cell phones, often for free or at a low cost.
Smarter Background Checks & Fraud Detection
AI streamlines background checks by cross-referencing data to create digital footprints. Private investigators increasingly rely on AI to detect fake identities, deepfakes, and financial fraud, filling gaps in traditional methods.
Conducting background checks can be time-consuming, but AI streamlines the process by cross-referencing multiple data sources to build a comprehensive digital footprint of a subject. Private investigators are increasingly tasked with detecting fraudulent identities, fake social media profiles, and deepfakes, a need now being addressed by AI solutions. Combining human reasoning with AI analysis in background checks, fake identity detection, deepfakes, and financial fraud leads to more informed decisions.
Social Media Investigations & Digital Footprint Tracking
AI-driven tools can monitor social media activity in real-time, helping PIs track a subject’s movements based on location-tagged posts. Analyze sentiment and behavior through keyword monitoring and pattern analysis and detect bots and fake accounts that could be involved in scams or misinformation.
Predictive Analytics & Risk Assessment
AI isn’t just about gathering data—it’s also about predicting behaviors. Investigators can use predictive analytics to:
Identify potential threats or risks based on historical behavior.
Anticipate movements by analyzing patterns in a subject’s activities.
Detect cybersecurity threats and digital fraud before they escalate.
The Battle Against Deepfakes & AI-Generated Deception
Each day, the line between reality and technological deception grows thinner. While AI aids investigators, it also introduces challenges like deepfakes and AI-generated scams.
Deepfake detection software from companies like Sensity, Microsoft, and Intel uses AI and machine learning to identify manipulated content. Modern PIs must leverage AI and deepfake detection tools to verify video and image authenticity while staying informed on AI-driven fraud techniques to protect clients from deception.
Automating Routine Investigative Tasks
AI can streamline case management for private investigators by:
Automating case file organization and data entry.
Assisting with legal research by cross-referencing case laws and court documents.
Providing AI-powered chatbots to help with client intake and initial case assessments.
The Future of AI in Private Investigations
Artificial intelligence is here to stay, and private investigators who adopt this technology will have a significant advantage in efficiency, accuracy, and effectiveness.
As AI becomes more mainstream, private investigators will likely specialize in narrower areas based on their expertise, but the demand for all of the services listed will increase. Clients may expect a broader range of services, such as digital tracking, fraud detection, and sentiment analysis, but investigators will likely focus on areas where their skills and AI tools align best, depending on their resources and the complexity of each task.
