Time-bound Contextual Bio-ID Generation for Minimalist Wearables
This addresses security and privacy issues for users of minimalist wearables, though it appears incremental as it builds on existing bio-ID concepts with a time-bound contextual twist.
The paper tackles the lack of real-time authentication in minimalist wearables, which risks data privacy and security, by introducing Proteus, a method that generates time-bound contextual bio-IDs from on-device sensor data, enabling dynamic device collaboration and human-to-device interaction.
As wearable devices become increasingly miniaturized and powerful, a new opportunity arises for instant and dynamic device-to-device collaboration and human-to-device interaction. However, this progress presents a unique challenge: these minimalist wearables lack inherent mechanisms for real-time authentication, posing significant risks to data privacy and overall security. To address this, we introduce Proteus that realizes an innovative concept of time-bound contextual bio-IDs, which are generated from on-device sensor data and embedded into a common latent space. These bio-IDs act as a time-bound unique user identifier that can be used to identify the wearer in a certain context. Proteus enables dynamic and contextual device collaboration as well as robust human-to-device interaction. Our evaluations demonstrate the effectiveness of our method, particularly in the context of minimalist wearables.
