Introduction: the DPDP Act and why integrity matters

India's Digital Personal Data Protection Act 2023 (the DPDP Act) sets the ground rules for how personal data is collected, used and protected in India. Much of the conversation around it focuses on consent and purpose, but a quieter theme runs through the whole framework: data integrity — the expectation that personal data stays accurate, complete and unaltered while it is in your care. For a Data Fiduciary, "DPDP Act data integrity" is not an abstract idea; it is a practical question of whether you can show that a record has not silently changed, been corrupted, or been tampered with. This article explains the integrity-relevant obligations in plain terms and shows how a Data Fiduciary can evidence integrity safeguards using e-Dex (formerly Hash Calculator). It is general information, not legal advice.

P26 in plain terms and does not make clause-by-clause legal claims. How the Act and its rules apply to your organisation depends on your specific facts and on the current text of the law as notified. Always read the provisions as they stand and take professional advice where the stakes warrant it. e-Dex is a tool that helps you produce integrity evidence; it is not a substitute for counsel or for a compliance assessment.

Frequently Asked Questions

What does the DPDP Act 2023 say about data integrity?
India's Digital Personal Data Protection Act 2023 expects a Data Fiduciary to keep personal data accurate and complete, to apply reasonable security safeguards, and to handle personal data breaches responsibly. Integrity sits across all three ideas: data should not silently change, be corrupted, or be tampered with. The Act states obligations in principle; the precise wording and rules should always be read as they currently stand. This article is general information, not legal advice.

Who is a Data Fiduciary under the DPDP Act?
Under the Digital Personal Data Protection Act 2023, a Data Fiduciary is broadly any person or organisation that alone or with others determines the purpose and means of processing personal data. In practical terms most Indian businesses, government bodies and platforms that decide why and how personal data is handled fall into this role, and they carry obligations around accuracy, security and breach handling.

How can a Data Fiduciary evidence data integrity safeguards?
A practical approach is to record a cryptographic baseline of important files or datasets, re-hash them periodically, and keep signed integrity certificates plus an audit trail of the results. Recording multi-algorithm hashes and a MATCH or MISMATCH verdict over time gives you contemporaneous, verifiable proof that a record has not silently changed. e-Dex produces such certificates offline on your own Windows machine.

Does e-Dex make my organisation DPDP compliant?
No. e-Dex supports evidence of integrity — it helps you demonstrate that a file or dataset is unaltered through hashes, signed certificates and an audit trail. It does not certify or guarantee DPDP compliance, which depends on your full programme of consent, purpose limitation, security, breach response and governance. Treat e-Dex as one technical control that contributes to the integrity part of the picture.

Does evidencing data integrity require sending data to the cloud?
No. e-Dex runs fully offline on your own Windows machine, so hashing files, comparing them against recorded values and generating integrity certificates all happen locally and your personal data never leaves your environment. This data-minimising, offline approach is well suited to organisations that want to evidence integrity without exposing personal data to third parties.

Conclusion

Data integrity runs quietly through the DPDP Act 2023 — in the duty to keep personal data accurate and complete, in reasonable security safeguards against unauthorised alteration, and in credible breach handling. A Data Fiduciary that can baseline, re-hash and issue signed integrity certificates has turned a principle into something demonstrable. e-Dex gives you that capability offline, in minutes, with personal data never leaving your machine — supporting evidence of integrity as one focused control within your wider programme.
