Understanding Digital Evidence

Understanding Digital Evidence

Digital evidence encompasses any information stored or transmitted in digital form that may be relevant to an investigation. Unlike physical evidence, digital evidence is fragile, easily altered, and often volatile. Understanding its characteristics is essential for proper handling:

Characteristics of Digital Evidence:

  • Volatility: Some evidence exists only in memory and disappears when power is lost
  • Volume: Modern systems generate vast amounts of potential evidence
  • Complexity: Evidence may be encrypted, compressed, or obfuscated
  • Fragility: Simple actions can alter or destroy evidence
  • Replicability: Exact copies can be made without degrading the original
  • Latency: Deleted data may be recoverable
  • Anonymity: Attribution can be challenging
