Abstract: A document acquisition and authentication system comprising a web-based application that on behalf of its users can automatically: a) collect Digital Documents, b) create standardized descriptive metadata related to each Digital Document, c) use that descriptive metadata to organize, sort, and filter the collected Digital Documents, d) collect and create evidence that third party users can use to judge the authenticity of particular Digital Documents, e) protect the users privacy during the collection, storage, and sharing of the Digital Documents. The web-based application provides users with functionalities including user management, Source management, automatic and manual document acquisition, and document management and sharing. The System can receive Digital Documents that users manually upload into it and it enables users to manually enter standardized descriptive metadata. The System can then automatically handle the other functions for the Digital Documents.
