For AR headset owners who are dissatisfied with the amount of AR content on closed corporate ecosystems, and creators who want their AR models to be discovered by more people, Blocktag lets anyone use their home printer as a factory to print security tags as secure Augmented Reality (AR) markers and stick them at public spaces. Unlike QR based markers, Blocktag protects the copyrights of creators as consumers have to use their phone or headset camera to authenticate the tag and their identity to trigger AR experiences.
