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： Systems and methods are provided for determining a depth map and a reflectivity map from a structured light image. The depth map can be determined by capturing the structured light image and then using a triangulation method to determine a depth map based on the dots in the captured structured light image. The reflectivity map can be determined based on the depth map and based on performing additional analysis of the dots in the captured structured light image.

摘要： Methods, devices and computer program products facilitate conditional access to a content embedded with watermarks. For such a content, when copy control rules associated with an embedded watermark message prohibits unconditional access to the content, it is determined whether or not an exception to the copy control rules exists, and if an exception to the copy control rules exists, the content is conditionally accessed. Additional watermark messages can be extracted while the content is being conditionally accessed, and based on the additionally extracted watermark messages, it is verified that conditional access to the content has been fulfilled.

摘要： Methods, devices, and computer program products facilitate the application of a content use policy based on watermarks that are embedded in a content. Watermark extraction and content screening operations, which can include the application of content usage enforcement actions, may be organized such that some or all of the operations can be conducted at different times by different devices. These operations can be conducted by one or more trusted devices that reside in a networked environment. The authenticity of various devices can be verified through the exchange of certificates that can further enable such devices to ascertain capabilities of one another. Based on the ascertained capabilities, an operational configuration for conducting watermark extraction and content screening can be determined.
