Electronic signatures come in multiple formats; each designed for different use cases. This article compares the widely used PAdES format with the XAdES format that powers SelfieSign's SVS (Selfie Video Signature) file, exploring how these technologies differ and what makes each suited to different scenarios.

Electronic signature laws are notoriously difficult to draft, revise, and interpret. They must balance legal provisions, real-world applications, cybersecurity controls, AND technical standards. This multifaceted complexity demands not just theoretical understanding, but practical insight into how these technologies actually function in diverse scenarios. 

The way we authenticate documents and verify identity has undergone a remarkable transformation throughout human history. From the clay seals of ancient civilizations to today's cutting-edge biometric verification systems, signatures continue to evolve at an unprecedented pace. In this article, we'll trace the fascinating journey of signature evolution through four distinct generations: Signing 1.0, 2.0, 3.0, and the most advanced 4.0.
