Cooperative impersonation, in which a legitimate user voluntarily shares their authentication credentials with another individual, poses a growing security threat in online services. Unlike conventional impersonation attacks, this threat is difficult to detect because it involves intentional cooperation between the user and the impersonator. To address this issue, this study explores CA (Cybernetic Avatar) log-based authentication, which leverages behavioral logs generated during service usage. While this method is promising for detecting cooperative impersonation, its applicability has often been limited to specific services due to the service-dependent nature of log data. To enable general-purpose use, we propose a classification framework for log data based on two dimensions: data type and service characteristics. Using logs from the online game CS:GO, we applied our classification and analyzed the effectiveness of different data types in authentication. Our findings indicate that time-series data effectively captures user-specific behaviors and is particularly useful for detecting cooperative impersonation. This research represents a step toward developing a reusable, service-independent log-based authentication method. |
