Abstract: A method and apparatus provide physical verification of a correct association between information printed on a closed face package and material and/or information contained inside the closed face package. A closed face package with a document or article inserted therein has a window permitting a portion of the document to be read from a location outside of the package. A first optical device is employed to read data printed on the package and a second optical device is employed to read document data, which document data is printed on the inserted document and appears through the window of the package. A data file is read to access account information stored therein corresponding to the document data. The accessed account information is compared with the package data to determine whether a matching association exists between the package data and the document data. If the matching association is determined to exist, the package is allowed to be further processed.

Abstract: A method of securing an object at an access level includes selecting a profile for a user, including a credential having an encrypted credential public key, an encrypted credential public key encryption key, and a multiple-level access identifier. A working key is generated by binding a domain value with a random value. The object is encrypted with the working key. A random value encryption key is generated based on the shared value by decrypting the credential public key encryption key with the profile key encryption key, decrypting the credential public key with the credential public key encryption key, generating an ephemeral key pair, and generating a shared value based on the ephemeral private key and the credential public key. The random value is encrypted with the random value encryption key, and the encrypted object, the ephemeral public key, and the encrypted random value are provided for an authorized recipient.
