| Abstract: |
Techniques for secure distribution of digital representations that combine encryption and watermarking. When a user at a client desires to download a digital representation, the user makes a request to a server for the digital representation, which encrypts the digital representation using a first key and downloads the encrypted digital representation to the user. Before the user performs any operation on the decrypted digital representation, a secret fingerprint watermark identifying the user is added to the digital representation. The fingerprint watermark is added either at the server or at the client and a copy of the fingerprinted digital representation is kept at the server. If the user makes an impermissible use of the digital representation, the secret fingerprint watermark can be used to identify the user. The request made by the user indicates the type of use that the user wished to make of the digital representation. If the use involves storage of the digital representation at the client, the server provides a second key that the client employs to encrypt the digital representation. If the user has permission to do so, the user may modify the digital representation and return the modified digital representation to the server for further distribution. In this case, the second key is used to encrypt the digital representation when it is sent to the server. The second key also serves as the user identification in the fingerprint watermark. If the user loses the second key, it can be recovered from the copy of the fingerprinted digital representation kept at the server. The first and second keys and any decrypted copy of the digital representation are kept in secure storage in the client.

What is claimed is:
1. Apparatus for manipulating an encrypted digital representation of a work that is received in the apparatus from an external source of digital representations, the apparatus comprising:
- a manipulator which causes the digital representation to be decrypted and further operated on in response to one or more inputs from a user of the apparatus; and
- a watermarker which operates in response to the manipulator to receive the decrypted digital representation and watermark the decrypted digital representation with a secret watermark that is received from an external watermark source and that indicates the user of the apparatus, the watermarker watermarking the decrypted digital representation prior to further manipulation thereof.
