A hybrid image blends the high-frequency component of one image with the low-frequency component of a different image. The high-frequency component is easily recognized from a short distance, but difficult to recognize from a long distance. On the other hand, the low-frequency component is easy to recognize from a long distance; however, it is difficult to recognize from a short distance. IllusionPIN, an authentication method based on hybrid images, was proposed in 2017. In IllusionPIN, a user and an observer recognize different digits on the same smartphone display. For example, when the user touches the digit 3 derived from high-frequency components, the observer recognizes 7 derived from low-frequency components. Although IllusionPIN is known to resist shoulder surfing, the authentication success rates and operation times of this method have not been reported. The present evaluation of IllusionPIN revealed a major problem: overlap of the digits derived from the high-and low-frequency components degrades the distinguishing ability, thereby reducing the success authentication rate to unacceptably low levels (approximately 77%). To improve the success authentication rate of IllusionPin, we slightly shift the drawing range of one digit. Evaluation results confirmed that after this improvement, the authentication success rate exceeded 90% without disturbing the shoulder-surfing resistance.

Summary Smartwatches are becoming increasingly ubiquitous as they offer new capabilities to develop sophisticated applications that make daily life easier and more convenient for consumers. The services provided include applications for mobile payment, ticketing, identification, access control, etc. While this makes modern smartwatches very powerful devices, it also makes them very attractive targets for attackers. Indeed, PINs and Pattern Lock have been widely used in smartwatches for user authentication. However, such authentication methods are not robust against various forms of cybersecurity attacks, such as side channel, phishing, smudge, shoulder surfing, and video‐recording attacks. Moreover, the recent adoption of hardware‐based solutions, like the Trusted Execution Environment (TEE), can mitigate only partially such problems. Thus, the user's security and privacy are at risk without a strong authentication scheme in place. In this work, we propose 2GesturePIN, a new authentication framework that allows users to authenticate securely to their smartwatches and related sensitive services through solely two gestures. 2GesturePIN leverages the rotating bezel or crown, which are the most intuitive ways to interact with a smartwatch, as a dedicated hardware. 2GesturePIN improves the resilience of the regular PIN authentication method against state‐of‐the‐art cybersecurity attacks while maintaining a high level of usability.
