Abstract

In a method of publishing creative content to at least one local digital display device, a first unit of the creative content is stored on a first portable digital storage medium in an encrypted format. The digital replication is encrypted with a selected one of a plurality of private encryption keys. The first portable digital storage medium is transferred to the local digital display device. A preselected public key is entered into the local digital display device. The preselected public key corresponds to the selected one of the plurality of private encryption keys. At least a portion of the first unit of the creative content is decrypted by employing the public encryption key using a public key/private key decryption algorithm. The portion of the creative content is displayed on the local digital display device.
