Digital Evidence And Privacy
Digital Evidence
Definition:
Digital evidence, also known as electronic evidence, refers to any probative information stored or transmitted in digital form that can be used in legal proceedings. This includes emails, text messages, social media posts, digital photographs, databases, logs from computers or servers, and data from IoT devices.
Characteristics of Digital Evidence:
Volatility: Digital evidence can be easily altered or deleted.
Fragility: Corruption or improper handling can render it inadmissible.
Authenticity Requirement: Must establish integrity and source.
Chain of Custody: Precise documentation is necessary to ensure evidence hasn’t been tampered with.
Legal Considerations:
Admissibility under laws like the Indian Evidence Act, 1872 (Sections 65A and 65B) and other jurisdictions.
The evidence must be authentic, relevant, and reliable.
Issues of privacy and consent are crucial in collection.
Privacy in the Digital Age
Definition:
Privacy refers to the right of individuals to control their personal information and to be free from unauthorized surveillance or intrusion. In digital contexts, privacy concerns include email monitoring, location tracking, social media profiling, and government surveillance.
Key Principles of Digital Privacy:
Consent: Data should not be collected without user consent.
Purpose Limitation: Data collected must be used for the stated purpose.
Data Minimization: Only necessary data should be collected.
Security: Adequate measures must protect stored and transmitted data.
