Method, system and computer-readable media for reducing undesired intrusion alarms in electronic communications systems and networks

A method, system and computer-readable media that enable the employment of an intrusion detection process are provided. This present invention is able to differentiate between certain malicious and benign incidents by means of a two-stage anomaly-based intrusion detection and prevention system. The invented system works at high-speed and with low-memory resources requirements. In particular, the invented method is implemented in a two-stage detector that performs coarse grain detection using sub-profiles 30A-30H (key features extracted from a profile) at one stage and fine grain (detailed behavioral profile) detection at another stage to eliminate unwanted attacks and false positives. Furthermore, in order to suppress specific alarms, the invented system allows the administrator to specify detailed profiles 32A-32H. By using a sub-profile extractor, a sub-profile is extracted, which is then downloaded into the coarse grain detector.

Minimally invasive spinal fusion

A system and method for performing spinal fusion using vertebral connecting rods constructed of a shape memory material, such as shape memory alloy. The connecting rod is cooled below its phase transition temperature, which is chosen to be just below body temperature, and is inserted through a curved guide tube previously inserted into the back of the patient. The guide tube is located so as to deliver the connecting rod at its desired location between the preinserted pedicle screw heads. The rod, being in its flexible state below the transition temperature, negotiates the curve and exits the guide tube in a straight form and parallel to the patient's spine. As it heats up to body temperature, it regains its original straight shape and its original rigidity, and is ready for connecting its associated vertebrae to each other.

Access Control System using Stimulus Evoked Cognitive Response

The ACSSECR invention is a biometric access control system and methodology that measures cognitive, psychophysiological responses to stimuli to confirm the identity of an individual. As an alternative to “Logging in” with a user ID and password, this cognitive biometric authentication system is used for “Cogging in” to a system with user ID and user-selected “Cogkey”. ACSSECR is designed for strict access control scenarios where significant authentication confidence is required to gain access to controlled information, facilities, systems, vehicles, or devices. The system takes advantage of a behavioral and physiological characteristic of humans that is an unconscious response to a stimulus. The Event Related Potential (ERP) response (specifically the P3 ERP) involuntarily occurs when an individual perceives and reacts to an unexpected, task-relevant event. The task is for the user to recognize their Cogkey which is presented infrequently amidst more frequent non-target stimuli. There is no requirement for extensive enrollment by users, only the recognition of their Cogkey. The basic system does not store biometric data for comparison, but rather measures the user's Cogkey recognition responses in comparison to non-Cogkey stimulus responses. An individual can have multiple personas with different Cog keys.
