Is there an official, recognized standard that this is based on? My understanding is that anything you deem as you signature, i.e., any type of symbol, is, by effect, your signature. I appreciate HelloSign's efforts, but it seems this is simply a market generating effort akin to things like home security systems. Even the process of motorization is a hold-over from a dying age. All the metadata of documents already create a signature that can be used for authentication. I am quite sure that HelloSign probably even uses some of those signatures for their validation process. It just kind of seems skeuomorphist. Do they support other images than squiggly lines of a varying unique manner to represent ourselves? I would like to design a logo or other image to use instead of a stone age process. Take East Asian signature seals....far cooler than squiggly lines in my opinion.
