Case Studies On Metadata And Ip Address As Evidence
Background
Metadata is data about data—such as time stamps, sender/receiver info, IP logs, location data—often used in digital investigations.
IP Address identifies devices on the internet and is vital for tracing the origin of online activity.
Courts analyze authenticity, chain of custody, and technical accuracy when admitting metadata/IP evidence.
