Metadata As Evidence Landmark Cases
What is Metadata?
Metadata is data that provides information about other data. In digital contexts, metadata can include:
Timestamps (creation, modification dates)
File size and type
Sender and recipient information in emails or messages
GPS location tags on photos or files
IP addresses and device information
Audit logs and access histories
Why is Metadata Important in Evidence?
Authenticity & Integrity: Metadata helps verify when and how digital evidence was created or modified.
Context: It provides context to the content, such as who sent a message and when.
Linking Evidence: Metadata can establish connections between suspects, communications, and timelines.
Chain of Custody: Shows how evidence was handled and preserved.
Challenges with Metadata Evidence
Manipulation risk: Metadata can sometimes be altered or spoofed.
Technical complexity: Requires expert testimony to interpret.
Admissibility debates: Courts must decide whether metadata is reliable and relevant.
