CEO at Custos Media Technologies
G-J van Rooyen is the co-founder and CEO of Custos Media Technologies, a Stellenbosch company that provides blockchain-based content protection for the film and publishing industries. Custos is a spin-out of Stellenbosch University, where G-J was Associate Professor in Information and Communications Technology prior to joining Custos full-time. He holds a PhD in Electronic Engineering from the same institution, and also founded the MIH Media Lab there: a post-graduate research laboratory with a strong focus on pre-commercial research in media technology. Custos was invented in the Media Lab, and the company embeds Bitcoin deposits directly into digital media files to discourage illicit redistribution. This gives media recipients “skin in the game” to protect valuable content that they receive. G-J regularly speaks on the concepts behind (and values of) cryptocurrency and blockchain, and strongly lobbies for light-handed regulation of these fledgling technologies.
