Intro to Digital Evidence - Cyber Clues Unveiled

  • Definition: Probative information stored or transmitted in binary form, crucial for legal proceedings.
  • Characteristics:
    • Volatile & fragile: easily altered, damaged, or erased with proper acquisition and preservation techniques essential.
    • Often circumstantial; can be direct.
  • Common Sources/Types:
    • Devices: Computers, mobiles, USB drives, HDDs, IoT devices, wearables, vehicle systems.
    • Data: Emails, messages, browser history, social media, cloud storage, encrypted platforms.
    • Logs: Server logs, network logs.
    • Metadata: Data about data (e.g., timestamps, file origin).

⭐ Admissibility of electronic records is governed by Sec 63 of the Bharatiya Sakshya Adhiniyam, 2023, requiring a certificate.

  • Core Statutes:
    • Information Technology Act, 2000 (IT Act): Defines "electronic record", "digital signature"; legal framework for e-transactions, cybercrime.
    • Bharatiya Sakshya Adhiniyam, 2023 (BSA): Provides framework for electronic evidence admissibility.
  • Key BSA Admissibility Sections:
    • Sec 63: Special provisions for electronic records and conditions for admissibility.
    • Sec 63(4): Certificate requirement for electronic evidence admissibility.
    • Sec 45: Opinion of Examiner of Electronic Evidence.
  • Relevant BSA Presumptions:
    • Sec 85: Re: electronic agreements and digital signatures.
    • Sec 86: Re: electronic records & digital signature certificates.
    • Sec 87: Re: presumptions concerning digital signatures.
  • Admissibility Pathway:

⭐ The Supreme Court ruling in Anvar P.V. vs P.K. Basheer & Ors. (2014) mandates a certificate under Section 63(4) of BSA for secondary electronic evidence admissibility.

Admissibility & Authentication - Proof & Pixels

  • Admissibility: Governed by Bharatiya Sakshya Adhiniyam (BSA), 2023. Electronic records admissible if relevant & authentic.
    • Sec 63 BSA: Mandatory for admissibility of secondary electronic evidence.
      • Requires certificate under Sec 63(4) detailing computer output circumstances.
  • Authentication: Verifying integrity & genuineness.
    • Methods:
      • Hash values (e.g., MD5, SHA-256) to ensure data integrity.
      • Digital signatures with BSA framework compatibility.
      • Chain of Custody: Documented trail of evidence handling.
      • Expert Opinion (BSA provisions for electronic evidence).
    • BSA 2023: Electronic Evidence Admissibility
  • Proof: Establishing facts using digital data ("pixels").
    • Challenges: Tampering, steganography, deepfakes.

⭐ The certificate under Sec 63(4) BSA is pivotal for the admissibility of secondary electronic evidence.

Doctor's Role & Digital Data - Docs & Data Detectives

  • Identification: Recognize relevant digital evidence: EMR/EHR, logs from medical devices (pacemakers, insulin pumps), CCTV footage, patient communications, mobile health app data.
  • Preservation: Ensure data integrity. Prevent unauthorized access, alteration, or destruction. Understand the critical importance of metadata.
  • Documentation: Meticulously record all steps for collection, handling, storage, and transfer. Essential for establishing chain of custody.
