Instrumented networks, computer systems and platforms having target subjects (devices, transactions, services, users, organizations) are disclosed. A security orchestration service generates runtime operational integrity profiles representing and identifying a level of threat or contextual trustworthiness, at near real time, of subjects and applications on the instrumented target platform. Methods and systems are disclosed for calculating security risks by determining subject reputation scores. In an embodiment, a system receives a query for a reputation score of a subject, initiates directed queries to external information management systems to interrogate attributes associated with the subject, and analyzes responses. The system receives a hierarchical subject reputation score based on a calculus of risk and returns a reputation token. In another embodiment, a method provides real time attestation of a subject's reputation to a service provider using an endpoint trust agent, and a trust orchestrator comprising a reputation broker and a trust broker.

The invention discloses a remote sensing image variation detection method based on region similarity. The detection method comprises the steps of: selecting tow-sence remote sensing images with different time phases in a monitored region, wherein the image data of the remote sensing images include multispectral data and panchromatic wave band data; carrying out the image preprocessing on the selected remote sensing images; combining all wave bands of the two remote sensing images in two periods after preprocessing into a one-scene image, dividing the one-scene image to establish the one-to-one mapping relationship of targets of the remote sensing images in two periods; establishing the feature set description of each target according to division results; calculating the region similarity between the targets according to the spectrum features of the targets, and carrying out algebraic calculus according to the textual features and NDVI features of the targets; building up a variable region detection criterion by setting a region similarity threshold value and combining the results of the algebraic calculus, and extracting the variable regions of the remote sensing images in two periods. The detection method can effectively eliminate the phenomenon of salt and pepper and improve the extract precision of the remote sensing image variable regions.
