A system, apparatus and method of displaying images based on image content are provided. To do so, a database of offensive images is maintained. Stored in the database, however, are hashed versions of the offensive images. When a user is accessing a Web page and the Web page contains an image, the image is hashed and the hashed image is compared to hashed images stored in the database. A match between the message digest of the image on the Web page and one of the stored message digests indicates that the image is offensive. All offensive images are precluded from being displayed.

A method, system, and program provide for voice mail management. A voice mail filtering controller calculates a separate Bayesian score for each voice mail message from among multiple voice mail message entries received into a voice mailbox for a user, wherein each separate Bayesian score indicates a probability that the associated voice mail message is unwanted by said user. During playback, the voice mail filtering controller automatically deletes a selection of the voice mail messages each with a separate Bayesian score greater than a particular Bayesian score of the last played voice mail message from the voice mailbox.

Exemplary embodiments of the present invention include a method for providing a password to an application. Such exemplary embodiments include receiving, from a user, a passkey event uniquely associated with one of a plurality of applications requiring a password, and receiving, from a user, a same master password for access to each of the plurality of applications, applying a hashing algorithm associated with the separate input event to the master password to generate an application specific password, and submitting the application specific password to the application for access by the user. In some embodiments, receiving, from a user, a passkey event uniquely associated with any given one of the plurality of applications includes receiving, from a user, an event created by a user's engaging a keyboard key.

The present invention provides a method, apparatus, and computer instructions for warning of a presence of a person in a zone having an inadequate security clearance. Movement of the person in the zone is detected. A message is broadcast to selected data processing systems associated with the zone, wherein the data processing systems initiate actions to protect data in the selected data processing systems.

A method and system for tracking a data processing system within a communications network are provided. According to one embodiment, a method is provided comprising receiving identity data from a data processing system via a communications network, where the data processing system comprises a security processing element associated with a secure storage element and the identity data specifies a portion of a security processing element endorsement key stored within the secure storage element. The described method embodiment further comprises identifying the data processing system utilizing the identity data and causing corresponding recovery data to be stored in response to an identification of the data processing system, where the recovery data comprises an associated network connection address.

A method and system for controlling interrupt frequency by transferring processor load information to a peripheral adapter provides adaptive interrupt latency to improve performance in a processing system. A device driver obtains current processor load information from an operating system or directly from processor usage counters. The estimated processor load is then used to set a parameter in the adapter that controls the frequency of an interrupt generator, which may be controlled by setting an interrupt queue depth threshold, packet frequency threshold or interrupt hold-off time value. The result is that the relative frequency of interrupts is managed in conformity with the current processor load, provide reduced processing latency when the system is relatively idle, which avoids loading the processor with additional interrupt processing overhead when the processor is busy.

A method, system, and program for mitigating self-propagating e-mail viruses are provided. A request to send an electronic mail message with a file attachment to intended recipients is received. A characteristic of the intended recipients are compared with a maximum recipient limit for the file attachment. If the characteristic of the intended recipients exceeds the maximum recipient limit for the file attachment, then a sender authorization is requested prior to sending the electronic mail message. The sender authorization is required such that if a virus is attempting to self-propagate by sending the electronic mail message, the attempt is mitigated.

摘要:
A method and system for controlling interrupt frequency by estimating processor load in the peripheral adapter provides adaptive interrupt latency to improve performance in a processing system. A mathematical function of the depth of one or more queues of the adapter is compared to its historical value in order to provide an estimate of processor load. The estimated processor load is then used to set a parameter that controls the frequency of an interrupt generator, which may be controlled by setting an interrupt queue depth threshold, packet frequency threshold or interrupt hold-off time value. The mathematical function may be the ratio of the transmit queue depth to the receive queue depth and the historical value may be predetermined, user-settable, obtained during a calibration interval or obtained by taking a long-term average of the mathematical function of the queue depths.

A balanced approach is provided for interrupt coalescing, wherein interrupts of locking and other small size packets are maximized, while large data segment interrupts are minimized. Thus, the most desirable interrupt characteristics of both large data segments and smaller packets are achieved. Usefully, a data processing system has an adapter connecting the system to a network to receive incoming packets of varying size, the incoming packets respectively carrying messages to interrupt the system processor. Each incoming packet is analyzed, to determine whether or not it meets one or more prespecified criteria, at least a first criterion being related to the size of the incoming packet. The processor is immediately interrupted in accordance with the interrupt message carried by the analyzed packet, if the packet meets all the prespecified criteria. If the analyzed packet does not meet all of the prespecified criteria, the processor is interrupted in accordance with a specified interrupt coalescing technique.
