Clock Around the Clock- Time-Based Device Fingerprinting

Explore a novel approach to hardware fingerprinting in this 20-minute conference talk presented at the Association for Computing Machinery (ACM). Delve into the technique of timing the execution of instruction sequences available in API functions to create unique device identifiers. Learn how this simple yet effective method can be performed remotely using JavaScript code. Examine the generation and comparison phases of this time-based fingerprinting technique, and understand its implications for device identification. Investigate preliminary tests, including the impact of CPU temperature and function selection. Gain insights into the methodology, see practical examples, and consider the broader implications of this innovative fingerprinting approach for web security and privacy.
