Methods and systems to allow for selective access to supplemental content that is associated with more generally distributed original content. In an embodiment, supplemental content may be encrypted, then integrated with original content using a steganographic technique. The resulting aggregated content may then be made available to users. Users may then extract the encrypted supplemental content from the original content. Those users having the proper privilege level may be given a cryptographic key to allow decryption of the supplemental content. Those without the necessary privilege will not be given this decryption key, and will therefore be unable to access the supplemental content.
