Abstract
Implementations of the present invention provide an authentication method for tagged items. The first portion of the authentication method includes determining an identifier associated with a tag for each of one or more items in a container and hashing the identifiers from the one or more items in the container creating a digest. The second portion of the authentication method is performed after the items are shipped or transferred. This second portion of the authentication method includes determining an identifier associated with a tag for each of the one or more items in a container, hashing the identifiers from the one or more items in the container to create a verification digest, determining if the verification digest matches a digest of the identifiers previously hashed and indicating that the contents of the container may have changed in response to the match determination.
