Context: The Opposition have demanded machine-readable electoral rolls from the Election Commission (EC), arguing that searchable formats are vital to detect duplicate or fraudulent entries.
About Electoral Rolls
What it is?
- Definition: An electoral roll is the official list of citizens eligible to vote in a constituency.
- Authority: Prepared and updated under the supervision of the Election Commission of India (ECI) through district-level officials.
- Dynamic Nature: Updated regularly to include new voters, remove deceased or shifted individuals, and correct errors.
- Access: Publicly available through the EC’s website in the form of PDFs split into hundreds of constituency “parts.”
About Machine-Readable Electoral Rolls
What It Is
- Rolls provided in text-searchable format (text-PDF or Excel/CSV) instead of image-only PDF.
- Allows computers to index, search, and analyse voter data quickly.
Working Mechanism
- Image PDF = Cannot be searched digitally; only human scrutiny works.
- Text PDF/CSV = Enables computer-based matching, duplicate detection, and large-scale verification.
- OCR (Optical Character Recognition) = Converts scanned image PDFs into machine-readable text, but this is costly and resource-intensive (millions of pages nationwide).
Why EC Stopped Providing Machine-Readable Rolls
- Data Privacy Concerns – Names and addresses could be misused by foreign entities.
- 2018 SC Case (Kamal Nath v. EC) – Supreme Court refused to compel EC to share text-based rolls.
- Internal EC Order (2018) – Directed States to upload only image-PDFs to protect voter identity.
- Security Risks – Potential misuse of searchable data for profiling, surveillance, or targeted political manipulation.
- Alternative Given – Political parties can convert PDFs themselves via OCR, though costly and cumbersome.
