Multi-workplace Biometrics Sign-on Using Serverless Architecture in the Cloud

May 2019 Presentation
Andrzej Knafel (Roche Diagnostics International, Ltd.)

This presentation describes using serverless architecture to address user sign-on in production environments where multiple users rotate between multiple workstations.


Software Engineering Institute




In certain production environments, such as clinical laboratories, users rotate among multiple workstations during a work shift, but their actions at a specific workplace should be audited and associated with appropriate activities. With existing authentication procedures, users must type their username and password hundreds of times per shift. This cumbersome interaction decreases productivity and, potentially, security as users try to apply workarounds. Hardware tokens, such as RFID tags, simplify the workflow but require read/write devices at each workplace, limiting universal adoption.

The popularity of photo cameras, microphones, and fingerprint scanners in mobile devices and computers and their integration with browsers make them interesting candidates for solving the authentication problem. However, most existing solutions are designed for the individual workplace, like a single device for one user. Due to the increased connectivity of the workplace, cloud computing can support biometric use for multi-workplace sign-on to increase usability and security. To avoid typing passwords many times per day, a face photo is used for convenience. To maintain a reasonable level of security, each user is required to sign on a minimum once per working shift using the username and password. The envisioned architecture utilizes serverless offerings of cloud service providers.
