Uniqueness and Reproducibility of Traffic Signatures

Abstract

Usable user authentication is an important research topic. The traffic signature-based approach is a new authentication technology that identifies the devices used by online users based on traffic signatures, where the traffic signature is a statistic of the video stream delivered by the authentication server to the user device. This approach has two advantages. First, users need not do any operations regarding the device identification. Second, users need not be sensitive to the privacy loss and computer theft. In this paper, an author evaluates the uniqueness and reproducibility of the signature by introducing a function that quantifies the distance between two signatures. Through number of experiments is demonstrated that the process interference approach has the advantage of generating new signatures that are sufficiently distinguishable from one another.
