<heading lvl="0">Abstract</heading> An automated trading exchange having integrated quote risk monitoring and quote modification services. An apparatus is implemented using at least one computer, having memory, and a processor. The computer is configured to receive orders and quotes, wherein specified ones of the quotes are contained in a quote group, and have associated trading parameters such as a risk threshold. Not all received quotes are required to have trading parameters as described herein. Preferably, the quote group contains all the quotes, or a subset of quotes, belonging to an individual market-maker for a given class of options contracts, or possibly the quotes of two or more market-makers that have identified themselves as belonging to a group for the purposes of risk monitoring and quote modification. The computer typically generates a trade by matching the received orders and quotes to previously received orders and quotes, and otherwise stores each of the received orders and quotes if a trade is not generated. The computer then determines whether a quote within the quote group has been filled as a result of the generated trade, and if so, determines a risk level and an aggregate risk level associated with said trade. The computer then compares the aggregate risk level with the market-maker's risk threshold, and if the threshold is exceeded, automatically modifies at least one of the remaining quotes in the quote group. The computer may also automatically regenerate quotes that have been filled.

A method for providing security to a computer network by selectively blocking network transmissions from selected IP addresses comprising the steps of: establishing a risk threshold whereby transmissions from IP addresses exceeding said risk threshold are selectively blocked; receiving a network transmission having an originating IP address and payload; analyzing the payload of said transmission and assigning a current risk rating to said IP address on the basis of said analysis; comparing the originating IP address of said transmission to a database of known IP addresses, each of said said previous cumulative assigned risk rating being based on at least one previous transmission from a known IP address; known IP addresses having a previous cumulative assigned risk rating, assigning a new cumulative risk rating to said originating IP address, said new cumulative risk rating being the sum of said current risk rating and said previous cumulative assigned risk rating for said originating IP address, with the proviso that where said originating IP address is not contained in said database of known IP addresses, the new cumulative risk rating will equal the current risk rating; logging the new cumulative risk rating for said originating IP address in said database of known IP addresses, with the proviso that where the originating IP address of said transmission is not contained in said database of known IP addresses, a new record is created for the originating IP address and said new cumulative risk rating in said database of known IP addresses; comparing said new cumulative risk rating to said risk threshold; and automatically blocking said transmission if said new cumulative risk rating exceeds said risk threshold.

A system and method for monitoring and delivering medication to a patient includes a controller that has a control algorithm and a closed loop control that monitors the control algorithm. A sensor is in communication with the controller and monitors a medical condition. A rule base application in the controller receives data from the sensor and the closed loop control and compares the data to predetermined medical information to determine the risk of automation of therapy to the patient. The controller then provides a predetermined risk threshold where below the predetermined risk threshold automated closed loop medication therapy is provided. If the predetermined risk threshold is met or exceeded, automated therapy adjustments may not occur and user/clinician intervention is requested.

Disclosed are embodiments a system and method for managing an on-line community. Electronic postings are pre-screened based on one or more metrics to determine a risk value indicative of the likelihood that an individual posting contains objectionable content. These metrics are based on the profile of a poster, including various parameters of the poster and/or the poster's record of objectionable content postings. These metrics can also be based on the social network profile of a poster, including the average of various parameters of other users in the poster's social network and/or a compiled record of objectionable content postings of other users in the poster's social network. If the risk value is relatively low, the posting can be displayed to the on-line community immediately. If the risk value is relatively high, display of the posting can be delayed until further content analysis is completed. Finally, if the risk value is above a predetermined high risk threshold value, the posting can be removed automatically.

An approach is provided in which an information handling system creates a first language profile corresponding to a first user account in response to determining that the first user account generated a first offensive message. The information handling system computes an accumulated risk score of the first user account based on correlating the first language profile to a second language profile corresponding to a second user account that generated a second offensive post. The accumulated risk score is based on a first risk score of the first user account and a second risk score of the second user account. In turn, the information handling system generates a notification in response to determining that the accumulated risk score reaches a risk threshold.

During a drilling operation, measured data from the drilling operation may be received with a panistic inversion and risk estimate module. The panistic inversion and risk estimate module may generate a plurality of mathematical solutions from a panistic inversion that uses the measured data and one or more earth models. The one or more earth models having various parameters may be selected prior to drilling and/or while the drilling operation occurs. For each solution of the plurality of mathematical solutions generated from the panistic inversion, the panistic inversion and risk estimate module may determine if the measured data exceeds one or more probability risk thresholds associated with the drilling operation. If the measured data exceeds the probability risk threshold associated with the drilling operation, then the panistic inversion and risk estimate module may generate an alert.
