The One-Dimensional Internet Seal innovatively combines a traditional seal pattern with a one-dimensional code. The general smart seal only adds a lock to a seal, but it lacks the means to verify its authenticity. However, The One-Dimensional Internet Seal uses blockchain technology, which gives us a new and safe way to verify the authenticity of the seal on paper documents.
First, the user uploads a remote authorisation form. Once approval is granted, the authorisation information can be sent to the smart seal. A lattice heating technique will then stimulate the underside of the smart seal to produce an authorised seal pattern and an encrypted one-dimensional code on the outer ring. The stamping process will be recorded by the camera, afterwhich any one can easily scan the seal to verify its authenticity.
