Strategy 4: Behavior Similarity Search
What is behavior similarity search
Behavior similarity search is a cybersecurity technique that uses advanced algorithms to identify and analyze patterns of user behavior, looking for unusual or potentially fraudulent activities and access attempts. This approach is primarily used to uncover account takeover attempts by identifying activities that deviate from the typical behavior patterns of a user within a financial services platform.
How does it work
Behavior similarity search works by employing machine learning (ML) algorithms and artificial intelligence (AI) to analyze large volumes of data relating to user activities within a given platform. The goal is to establish a baseline of normal user behavior by understanding the various aspects, such as login times, devices used, session durations, and transaction patterns.
Once the baseline is established, the system constantly compares new user activities against this baseline, and any deviations or anomalies are flagged as potential fraud attempts. This method uses advanced statistical modeling and analysis techniques to identify correlations and similarities in behavior while ignoring noise in the data.
Pros & Cons
Pro: Early identification of potential fraud
Behavior similarity search allows for early identification of potential account takeover and fraud attempts by flagging unusual behavior patterns before they result in any harm to the user or the financial services platform.
