Abstract: Systems and methods are provided for the detection and prevention of intrusions in data at rest systems such as file systems and web servers. Item requests are examined to determine if the request and/or the result violates an item access rule. If either the request or the result violates the item access rule, an access control manager is alerted and appropriate action is taken such as not complying with the item request. Embodiments of the invention also produce a scorecard to represent the severity of an intrusion threat.

Abstract: A computer OS with an extended file attribute (EFA) is proposed to extend, without modifying a legacy virtual file system, the legacy file attribute of legacy files where each legacy file includes a file content and a legacy file attribute. The OS has a file attribute extension mechanism for adding EFA to the legacy file attribute. The file attribute extension mechanism includes: a) During EFA creation, adding EFA to legacy file attribute by concatenating an encoded file content extension to the file content. b) During EFA access, decoding the encoded file content extension and accessing the EFA. Also included is an Application Programming Interface (API) mechanism for generating system call to access each file. In turn, the system call firstly calls the legacy virtual file system to access each file plus legacy file attribute and concatenated encoded file content extension, and secondly accesses EFA via the file attribute extension mechanism.

Abstract: A physiological monitoring device receives a plurality of physiological measurements, including the user's diastolic and systolic blood pressure, pulse rate and body temperature. The physiological measurements are stored in a memory which is controlled by a microprocessor. The microprocessor organizes the measurements and causes the measurements to be displayed for analysis on a screen in either digital or graph form, printed in either digital or graph form and/or transmitted over a phone line or other communication link for reproduction in either digital or graph from at a distant receiver located, for example, in a doctors office or hospital.
