Abstract: A method and system for detecting the presence of a plug-in on a client computer; and if the plug-in is not present, downloading the plug-in to the client computer; loading the plug-in into a browser running on the client computer and processing events generated on the client computer using the code contained in the plug-in.

Abstract: A system and a method for configuring an action set for use in dynamically processing network events in a distributed computing environment are described. A graphical user interface associated with an action set is presented. An action set is stored into a database. At least one network event and at least one sensor are associated responsive to a user selection indicated on the graphical user interface. At least one action is embedded into the action set responsive to a user selection indicated on the graphical user interface. The association for the at least one network event and the embedding of the at least one action are stored into a mapping table.

Abstract: A system and method for managing scarce computer system memory resources has three aspects. A first aspect allows large data structures to be replaced by a pointer that causes an intentional fault to occur. The fault is trapped, and the invention interposes the required data. A second aspect associates data structures with both the task and the module that own the structure. The structure can be eliminated from memory when both the owning task and the owning module have terminated. A third aspect utilizes swapping techniques to maintain multiple local data areas for multiple tasks. In conjunction the three aspects of the invention provide improved resource availability and substantially unimpaired system performance.

Abstract: A system and method update client computers of various end users with software updates for software products installed on the client computers, the software products manufacturered by diverse, unrelated software vendors. The system includes a service provider computer system, a number of client computers and software vendor computer systems communicating on a common network. The service provider computer system stores in an update database information about the software updates of the diverse software vendors, identifying the software products for which software updates are available, their location on the network at the various software vendor computer systems, information for identifying in the client computers the software products stored thereon, and information for determining for such products, which have software updates available. Users of the client computers connect to the service provider computer and obtain a current version of portions of the database.

Abstract: A system and method for actively marketing products and services to a user of a client computer such as over a network are disclosed. A product information database comprising product summary files that facilitate determination of presence or absence of products associated with the client computer, a marketing rule knowledge base comprising opportunity rule files governing marketing opportunities, and an opportunity detection object for determination of marketing opportunities are utilized to determine active marketing opportunities and may be downloaded to the client computer from a service provider computer system. The opportunity detection object may comprise a scan engine, an opportunity analysis engine, and a presentation engine which collectively determine and present marketing information to the client computer user.

Abstract: A cryptographic-enabled messaging system providing a “Policy Management Agent” is described. The Policy Management Agent works in conjunction with a standard mail server, such as an SMTP (Simple Mail Transport Protocol) mail server, to ensure that incoming and outgoing e-mail adheres to the policies that are specified for a given site. Specifically, the Agent intercepts e-mail normally bound for the mail server and checks to make sure that it conforms with policies configured for one's site (e.g., corporate site). If the e-mail adheres to the policies for the site, it is forwarded to the mail server where it is routed to the intended recipient. If the e-mail does not adhere to the policies specified for the site, a message of one's choosing is sent to the client indicating that the e-mail was rejected. In an exemplary embodiment (e.g.

Abstract: A cryptosystem having a Certificate (Key) Server for storing and maintaining certificate or key information in a certificate database is described. The Certificate Server allows clients to submit and retrieve keys from a database based on a set of policy constraints which are set for one's particular site (e.g., company). Access to the Certificate Server is maintained by a Certificate Policy Agent, which makes sure that the policy is enforced for a given site based on the information supplied during the configuration. During operation, the Certificate Server responds to client requests to add, search for, and retrieve certificates. The server accepts or rejects certificates based on configurable parameters enforced by a Certificate Policy Agent. When a certificate is submitted to the server, the Certificate Policy Agent checks to see if it meets the criteria for a given site based on the settings specified during the configuration.

Abstract: A cryptosystem is described which automatically provides an extra “message recovery” recipient(s) when an encrypted message is generated in the system. The system is typically configured such that the extra recipient or “message recovery agent” (MRA)—an entity which itself has a public key (i.e., a MRA public key)—is automatically added, under appropriate circumstances, as a valid recipient for an encrypted message created by a user. In a corporate setting, for example, the message recovery agent is the “corporate” message recovery agent designated for that company (firm, organization, or other group) and the user is an employee (or member) of that company (or group). In operation, the system embeds a pointer (or other reference mechanism) to the MRA public key into the public key of the user or employee, so that encrypted messages sent to the company's employees from outside users (e.g.

Abstract: A high temperature sensing probe includes an optical fiber or rod having a distal end and a proximal end. The optical fiber or rod has a coating secured to the distal end thereof, wherein the coating is capable of producing a Raman spectrum when exposed to an exciting radiation source.
