COMPUTER-BASED SYSTEMS FOR PROTECTING SHIPPING INFORMATION

This disclosure describes computer-based techniques for controlling access to shipping information for packages by providing limited shipping information to a courier to advance the package to a next node along a transit route. An administrator computer generates a set of components for a transit state of and information about the package. The set of components represents constituent “tokenized” portions of a delivery address, such as a sender or recipient name, street number, street name, city, or zip code. The transit states of the package represent various transit functions of the courier, such as pick-up, correct handling, sorting, delivery, return, and exception. The administrator computer generates sets of components that enable the courier to advance the package to a next node, but that exclude shipping information that may not be useful for advancing the package. The administrator computer sends the set of components to the courier based on the current transit state of the package.
