A rights management arrangement for storage media such as optical digital video disks (DVDs, also called digital versatile disks) provides adequate copy protection in a limited, inexpensive mass-produceable, low-capability platform such as a dedicated home consumer disk player and also provides enhanced, more flexible security techniques and methods when the same media are used with platforms having higher security capabilities. A control object (or set) defines plural rights management rules for instance, price for performance or rules governing redistribution. Low capability platforms may enable only a subset of the control rules such as controls on copying or marking of played material. Higher capability platforms may enable all (or different subsets) of the rules. Cryptographically strong security is provided by encrypting at least some of the information carried by the media and enabling decryption based on the control set and / or other limitations. A secure "software container" can be used to protectively encapsulate (e.g., by cryptographic techniques) various digital property content (e.g., audio, video, game, etc.) and control object (i.e., set of rules) information. A standardized container format is provided for general use on / with various mediums and platforms. In addition, a special purpose container may be provided for DVD medium and appliances (e.g., recorders, players, etc.) that contains DVD program content (digital property) and DVD medium specific rules. The techniques, systems and methods disclosed herein are capable of achieving compatibility with other protection standards, such as for example, CGMA and Matsushita data protection standards adopted for DVDs. Cooperative rights management may also be provided, where plural networked rights management arrangements collectively control a rights management event on one or more of such arrangements.

Methods and systems for remotely configuring and monitoring a communication device are provided, especially useful in a computer network environment such as the Internet. A communication device or network appliance compares communications entering the communication device to a list of communication types established as known security risks, for example hacker attacks, unauthorized attempted access to network resources, or similar network security threats. If the received communication corresponds to a known security risk, the communication is classified as either a high security risk or low security risk, and an alert signal is transmitted to a remote monitoring center. Upon receiving the alert signal, the remote monitoring center assigns a priority to the alert signal based upon the type of the communication that triggered the transmission of the alert signal. Based on the assigned priority, the prioritized alert signal is then forwarded to a remote monitoring agent for resolution. The remote monitoring agent may then analyze the communication, contact the end user of the communication device with an appropriate resolution, or take other appropriate action in response to the received communication. The communication device may also be remotely configured.

Systems and methods are disclosed to control the temperature of an RF hyperthermia system with minimum overshoot and to improve safety by, among other things, detecting a defective temperature sensor. Temperature overshoot may be minimized by compensating for the short-term temperature difference between the area being treated and the applicator delivering the RF energy. The RF energy may heat the tissue and then the tissue may transfer heat to the applicator sensor. The system may also adapt to various applicator sizes and shapes by modifying control loop coefficients based on initial probe response.
