Digital Evidence in Court

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.

Indian Legal Framework - Bytes & Barristers

• 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).
  • 
• 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.
• Legal & Ethical Compliance: Strictly adhere to data privacy laws (e.g., DPDP Act, 2023) and professional ethical guidelines.
• Expert Testimony: Clearly and objectively explain digital findings and their medical significance in legal proceedings.

⭐ Section 61 of the Bharatiya Sakshya Adhiniyam, 2023, mandates a certificate for the admissibility of electronic records as primary evidence.
