20090119624 | APPARATUS AND METHOD FOR ANALYZING SOURCE CODE USING PATH ANALYSIS AND BOOLEAN SATISFIABILITY - A computer readable storage medium includes executable instructions to identify a path in target source code. Constraints associated with the path are extracted. The constraints are converted to a Boolean expression. The Boolean expression is processed with a Boolean satisfiability engine to identify either a feasible path or an infeasible path. A feasible path is statically analyzed, while an infeasible path is not statically analyzed. | 05-07-2009 |
20090119648 | APPARATUS AND METHOD FOR ANALYZING SOURCE CODE USING MEMORY OPERATION EVALUATION AND BOOLEAN SATISFIABILITY - A computer readable storage medium includes executable instructions to identify a memory operation in target source code. A set of constraints associated with the memory operation are developed. The constraints are converted into a Boolean expression. The Boolean expression is processed with a Boolean satisfiability engine to determine whether the memory operation is potentially unsafe. | 05-07-2009 |
20090282480 | Apparatus and Method for Monitoring Program Invariants to Identify Security Anomalies - A computer readable storage medium includes executable instructions to insert monitors at selected locations within a computer program. Training output from the monitors is recorded during a training phase of the computer program. Program invariants are derived from the training output. During a deployment phase of the computer program, deployment output from the monitors is compared to the program invariants to identify security anomalies. | 11-12-2009 |

20110238746 | Methods and systems of client-side caching of pages with changing content - The present invention relates to Internet based and web applications and the need to reduce page latency and bandwidth usage. The invention can achieve these goals by making use of the cache built in to standard web browsers. In one embodiment, the invention provides that a web application user will use their browser to request a page from the application web server, which responds with a small page that includes a script. The script appends a previously established cookie value to the URL originally requested and the browser then re-requests the URL with the appended cookie value. (The server computes the cookie value based on the last modified time of the data used to generate the page.) If the most recent version of the page is in the browser cache, the browser gets a cache hit, which means the page is retrieved from browser cache rather than from the server, rapidly displaying the page to the user. If, on the other hand, there is only an older version of the page in the browser cache, there is a cache miss (because the rewritten URL will not match any URL in the cache) and the browser will send the request to the server to retrieve the most recent version of the page. | 09-29-2011 |

20130086676 | CONTEXT-SENSITIVE TAINT ANALYSIS - In one implementation, a taint processing applied to a tainted value of an application is identified and an output context of the application associated with output of the tainted value is determined. A notification is generated if the taint processing is incompatible with the output context. | 04-04-2013 |
20130086687 | CONTEXT-SENSITIVE APPLICATION SECURITY - In one implementation, a tag is associated with a tainted value of an application and an output context of the application that is associated with output from the application that includes the tainted value is determined. A taint processing is a applied to the tainted value in response to the output of the tainted value, the taint processing is compatible with the output context. | 04-04-2013 |
20130160130 | APPLICATION SECURITY TESTING - In one implementation, an attack surface identification system defines an interface description of an application during execution of the application. The interface description is then provided to a scanner. | 06-20-2013 |
20130160131 | APPLICATION SECURITY TESTING - In one implementation, an application security system accesses an attack description and a data set from an application. The data set based on an attack data set. The application security system correlates the data set with the attack description, and reports a security vulnerability for the application if the data set satisfies the attack description. | 06-20-2013 |
20140082739 | APPLICATION SECURITY TESTING - The present disclosure provides a system that includes a server hosting an application under test (AUT), an observer configured to monitor instructions executed by the AUT, and a computing device communicatively coupled to the AUT and the observer through a common communication channel. The computing device may be configured to send an application request to the AUT, wherein the application request is configured to expose a potential vulnerability of the AUT. The computing device may receive an application response from the AUT in accordance with the AUT's programming. The computing device may send a service request to the observer, and receive a service response from the observer that contains information corresponding to the instructions executed by the AUT due to the application request, information about the AUT, or information about a server hosting the AUT. | 03-20-2014 |

20110105853 | SYSTEMS AND METHODS FOR HEALTHCARE DELIVERY, OBSERVATION, AND COMMUNICATION BETWEEN A DE-CENTRALIZED HEALTHCARE SYSTEM AND A PATIENT LIVING AT HOME - The disclosure describes de-centralized healthcare systems and methods of using the same to provide healthcare to a subject living at home. A de-centralized healthcare system of the invention provides at or above hospital-level care through the implementation of care pathway protocols for effective treatment of designated health conditions. A subject is monitored by a central station, which is staffed by healthcare practitioners and providers. A dispatch system allows healthcare providers to visit the subject for appointments and deliveries. The de-centralized healthcare system provides for the subject's laboratory, nutrition, and hygiene needs. | 05-05-2011 |

20140341777 | METHODS, SYSTEMS, AND DEVICES FOR HIGH-LEVEL DISINFECTION - A disinfection device includes a disinfection chamber into which a radiation source emits ultraviolet-C (UV-C) radiation. A radiation sensor detects the amount of UV-C radiation within the disinfection chamber, and a temperature sensor produces temperature values of a temperature within the disinfection chamber. A processing unit generates accumulated UV-C radiation values and verifies that the accumulated UV-C radiation value in the disinfection chamber reaches a first radiation threshold while also verifying that the temperature in the disinfection chamber stays below a first temperature threshold. The UV-C radiation may be emitted into the disinfection chamber over one or more fixed periods of time while the total time for the disinfection process is limited to a primary time interval. The process may terminate successfully if the first radiation threshold is exceeded before the primary time interval expires. The disinfection device provides high level disinfection of contaminated articles in a short time and at a low temperature. | 11-20-2014 |
