In the era of information technology, technology advancements have changed human lives by a lot. However, document delivery, especially commercial and important ones, are still following years old methods, physical mailing. Physical mailing takes a lot of time and spends a lot of resources. There are ways to deliver data via digital channels like emails, BitTorrent, instant messaging and centralized servers. However, only physical mailing allows the document to be confidential, provides trustworthy mailing record, and easy to use. Hence, it is still dominant even in this highly digitized world. Besides, it is well-known that all printed documents/ credentials are potentially subject to forgery. Every year, billions USD has lost directly due to document fraud. With a vision of “building trust across real and digital world”, Authpaper limited has been providing document anti-forgery software solutions and computer investigation services for years and obtained patent, academic publications, supports and international awards. In 2018, we start a new project Authpaper Delivery which combines blockchain and other current technologies to build a peer-to-peer digital data delivery platform. All data delivered is confidential except the specified recipients. Data is verified to be unchanged down to every single bit. Operations on the data are properly done and recorded among the peers so that the delivery histories are public verifiable yet unforgeable. Peers are rewarded by delivering the digital data and helping to run the platform with good will. Authpaper Delivery is also a platform for users to issue document with unforgeable certifications. Besides, this platform allows users to deliver huge digital copyright information securely, like movies, software and even system images. We are now selling Authpaper Coin (AUPC) to raise support to continue the development. Please check https://authpaper.io for details.
