Abstract
A method, non-transitory computer readable medium and apparatus for decrypting a document are disclosed. For example, the method captures a tag on an encrypted document, transmits the tag to an application server of a communication network to request a per-document decryption key, receives the per-document decryption key if the tag is authenticated, and decrypts a portion of the encrypted document using a temporary decryption key contained in the tag, the tag decrypted with the per-document decryption key.
