    摘要: 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.

    摘要: Techniques for protecting the security of digital representations, and of analog forms made from them. The techniques include authentication techniques that can authenticate both a digital representation and an analog form produced from the digital representation, an active watermark that contains program code that may be executed when the watermark is read, and a watermark agent that reads watermarks and sends messages with information concerning the digital representations that contain the watermarks. The authentication techniques use semantic information to produce authentication information. Both the semantic information and the authentication information survive when an analog form is produced from the digital representation. In one embodiment, the semantic information is alphanumeric characters and the authentication information is either contained in a watermark embedded in the digital representation or expressed as a bar code. With the active watermark, the watermark includes program code. When a watermark reader reads the watermark, it may cause the program code to be executed. One application of active watermarks is making documents that send messages when they are operated on. A watermark agent may be either a permanent resident of a node in a network or of a device such as a copier or it may move from one network node to another. In the device or node, the watermark agent executes code which examines digital representations residing in the node or device for watermarked digital representations that are of interest to the watermark agent. The watermark agent then sends messages which report the results of its examination of the digital representations. If the watermarks are active, the agent and the active watermark may cooperate an the agent may cause some or all of the code than an active watermark contains to be executed.

    摘要: The invention provides methods and compositions for the modulation of proanthocynidin (“PA;” condensed tannin) production in plants. The methods of the invention allow creation of plants having novel phenotypes, such as alterations in levels of PA or in the types of tissues in which PAs are produced. Altered expression of PA in plants may be achieved, for instance without significantly affecting anthocyanin content or overall secondary metabolite profiles. Alternatively, expression of PA in plants may be achieved while also affecting anthocyanin content.

The method includes ranking data links between the plurality of base stations and the plurality of mobile stations according to a quality criterion, and selecting a subset of data links for transmitting the data between the plurality of base stations and the plurality of mobile stations such that a predetermined requirement is satisfied. Selecting the subset of data links may include iteratively assigning a predetermined value to power of the data link having the lowest ranking and determining if the predetermined requirement is satisfied, until the predetermined requirement is no longer satisfied. The remaining data links may then be selected for transmitting the data between the plurality of base stations and the plurality of mobile stations.
