Dynamic control of authorization to access internet services
A system for managing authorization to access Internet services. A session object is created when a user logs onto a web site. The session object includes authorization-privilege information for N services. The user selects the service desired from the web site, at which point the server checks the session object. If the session object does not include authorization to access the selected service, the server consults a directory service. If the user is authorized according to the directory service, authorization-to-access information is incorporated into the session object. When authorization is conditional, a listener object is created within the session object. The listener object registers with a broadcast object and receives information germane to conditions of authorization. The listener object analyzes the information according to conditions of authorization, and terminates access to the selected service when conditions of authorization are not satisfied.

Then, at the next risk assessment scan, a determination may be made as to whether the attack is actually occurring and, if so, more effective and performance altering techniques may be utilized to counter the attack.

Mechanism to provide software guaranteed reliability for GSM operations
In a global shared memory (GSM) environment, an initiating task at a first node with a host fabric interface (HFI) uses epochs to provide reliability of transmission of packets via a network fabric to a target task.

Secure method and system for biometric verification
There is a need in the computer software and data industries to protect content from unauthorized access to private information. Alphanumeric passwords have been shown to offer very weak protection. Biometrics (personal traits such as fingerprints and hand-written signatures) offer superior protection, but still have a number of weaknesses. The most significant weakness is that there is no existing way to protect the stored biometric data itself; and once a person's fingerprint data has been obtained by an attacker, the use of that fingerprint can no longer be considered secure. The invention solves the problem by securing the access software application that manages the biometric data using tamper-resistant encoding techniques. These tamper-resistant encoding techniques include: data-flow, control-flow, mass-data and white-box encoding.

Thermal control of memory modules using proximity information
An information handling system includes a processor having access to a system memory. The system is operable to detect a thermal alert and identify an associated portion of system memory. The system may then modify memory allocation information used by an operating system to allocate system memory. When the thermal alert indicates a rising memory module temperature that exceeds a specified threshold, the modification of the memory allocation information causes the memory to appear to be more “distant” from the system processor(s) and thereby allocated less preferentially than other memory. If the temperature continues to rise beyond a higher threshold, a second modification of the memory allocation information is performed to simulate a “hot eject” of the memory module. As the memory module cools, the memory allocation information can be restored to simulate a hot add of the memory module and to restore the proximity of the memory module.

Method and system for achieving fair command processing in storage systems that implement command-associated priority queuing
In certain, currently available data-storage systems, incoming commands from remote host computers are subject to several levels of command-queue-depth-fairness-related throttles to ensure that all host computers accessing the data-storage systems receive a reasonable fraction of data-storage-system command-processing bandwidth to avoid starvation of one or more host computers.

A liquid crystal display panel including two substrates combined together through a sealing material applied to a peripheral portion thereof. A liquid crystal is sealed between the substrates, and there is a picture-frame area on the substrates, outside a display area and inside a region where the sealing material is formed. A light-shield film is formed in the picture-frame area in the form of a frame surrounding the display area, wherein the light-shield film does not overlap the sealing material. A first conductive film is formed in the picture-frame area on either of the substrates, outside the light-shield film, in the form of a continuously connected frame surrounding the display area and in the same layer as a pixel electrode formed at each pixel in the display area. A second conductive film is formed on the other of the substrates, facing the first conductive film.
