Looking Inside the Black-Box: Capturing Data Provenance Using Dynamic Instrumentation

Knowing the provenance of a data item helps in ascertaining its trustworthiness. Various approaches have been proposed to track or infer data provenance. However, these approaches either treat an executing program as a black-box, limiting the fidelity of the captured provenance, or require developers to modify the program to make it provenance-aware. In this paper, we introduce DataTracker, a n...

Playing Inside the Black Box: Using Dynamic Instrumentation to Create Security Holes

Programs running on insecure or malicious hosts have often been cited as ripe targets for security attacks. The enabling technology for these attacks is the ability to easily analyze and control the running program. Dynamic instrumentation provides the necessary technology for this analysis and control. As embodied in the DynInst API library, dynamic instrumentation allows easy construction of ...

Inside-outside technique for posterior occipitocervical spine instrumentation and stabilization: preliminary results.

OBJECT The authors present a series of 16 patients who underwent inside-outside occipital and posterior cervical spine stabilization. METHODS In this technique, the screw was placed from the inside of the occiput to the outside. An articular (lateral) mass plate was contoured to the shape of the occipital bone and the cervical spine and affixed to the occiput with a flat-headed screw or stud ...

Minimal Instrumentation

Feature location is a commonly occurring problem in software reuse and maintenance. In understanding large software systems, Software Engineers need to locate the different software components that work together to provide a specific end user feature. Because of its importance, this problem has generated much interest among software maintenance researchers and a number of different methods of a...
