  1. SPADE on Android http://data-provenance.googlecode.com/

  2. What is Provenance? • Origin or history of objects. • In computing terms, data provenance  history of data or computation. • Represented as a graph, modeled using OPM1. • Vertices show objects (data, users, processes). • Edges show transformations or relationships between objects. [1] Open Provenance Model – http://openprovenance.org/

  3. Provenance – Uses • Analyze, debug applications • Optimize, re-execute workflows • Intrusion detection • Malware analysis

  4. SPADE – Overview • Software infrastructure for collection, management, analysis of data provenance. • Cross-platform with a domain agnostic kernel. • Extendible, can dynamically load modules for particular environments or needs.

  5. SPADE – Android • Reporting: strace – system calls used to generate data provenance. • Monitor zygote, DalvikVM, radio, system processes. • Storage: Graphviz DOT format.

  6. Provenance Graph

  7. Analysis of Captured Provenance • Import graph inside query tool. • Ability to ask for the following information using query commands: • Vertices that match a given expression • Lineage (ancestors or descendants) • Paths between vertices
