Yet erasure of data influence embedded in a trained model is qualitatively different from removal of access to discrete information. This paper proposes a framework integrating machine unlearning with zero-knowledge cryptographic proof systems to create verifiable compliance mechanisms. The objective is not metaphysical forgetting but procedural and mathematically demonstrable exclusion proving, with cryptographic certainty, that a specific data point was not included in the dataset used to train or retrain a model.<\/p>\n<p style=\"font-weight: bold;\">Right to erasure (RTE) under the DPDP Act: Legislative framework<\/p>\n<p style=\"margin-bottom: 3%;\">The application of this Act is on the processing of digital personal data within the territory of India and extends overseas with respect to offering goods or services to data principals within India.

Section <a href=\"https:\/\/www.scconline.com\/DocumentLink.aspx?q=JTXT-9001593452\" target=\"_blank\">12(3)<\/a> provides that a data principal may request erasure, and the data fiduciary must comply unless retention of such data is essential for any prescribed purpose.<\/span><a id=\"fnref5\" href=\"#fn5\" title=\"5.

The Justice B.N. Srikrishna Committee, which laid the intellectual groundwork for India&#8217;s data protection framework, had envisaged erasure as a core component of individual data autonomy, emphasising that the right to have personal data erased is essential to preventing the indefinite persistence of information that may be outdated, irrelevant, or harmful.<\/p>\n<p style=\"margin-bottom: 3%;\">However, the statute does not provide technical guidance on how erasure should operate when personal data has been incorporated into the training of AI systems. There is no statutory distinction between structured database storage and machine learning training data. The Act does not define what constitutes erasure in the context of data that has been used to train a statistical model and has thereby contributed to the adjustment of parameters that collectively determine the model&#8217;s behaviour. This silence creates significant interpretive challenges. Two legal questions emerge with particular force. <span style=\"font-style: italic;\">First<\/span><\/span><span style=\"font-style: italic;\"><\/span><!-- Fisrt, Second and Third to be ital or roman? --><\/span><\/span><\/span><\/span><!-- Edit to firstly and others and mark ital --><\/span><span style=\"Open Sans&quot;; font-size: 12.5pt;\"><span style=\"font-style: italic;\">ly<\/span>, does erasure require only the removal of the data record from the data fiduciary&#8217;s storage systems, or does it also require the removal of the data&#8217;s influence from trained models that were built using that data? <span style=\"font-style: italic;\">Secondly<\/span>, what constitutes adequate proof of compliance with an erasure request when the data in question has been processed through a machine learning pipeline?<\/span><\/p>\n<p style=\"margin-bottom: 3%;\">If a model continues to reflect patterns derived from an individual&#8217;s data, the right to erasure risks becoming symbolic rather than substantive. An individual whose personal data was used to train a model that subsequently makes decisions affecting her, such as credit scoring, insurance pricing, or content recommendation, may find that the erasure of her raw data record provides no meaningful relief if the model&#8217;s parameters continue to encode her data&#8217;s statistical influence. At the same time, requiring complete retraining from scratch for every individual erasure request may be economically and computationally infeasible, particularly for large-scale models trained on millions or billions of data points. The legislation also addresses the conflict between personal freedom and technical progress.

However, full retraining is often prohibitively expensive. Bourtoule and others proposed Sharded, Isolated, Sliced, and Aggregated (SISA) training, which partitions data into isolated shards, each training a separate sub-model, only the affected shard requires retraining upon erasure.

In conventional databases, a regulator can examine records and audit logs to confirm deletion. In AI systems, verification is qualitatively different: the question is whether a trained model has been modified to remove the influence of a specific data point.

This root hash is published or deposited with a trusted third party or Regulatory Authority before training begins. The Merkle tree structure has two important properties. <span style=\"font-style: italic;\">Firstly<\/span>, it is tamper-evident<\/span><\/span><!-- Tamper-evident or tampered evident? --><\/span><\/span><\/span><!-- As is --><\/span><span style=\"Open Sans&quot;; font-size: 12.5pt;\">; any modification to any data record changes the corresponding leaf hash, which propagates through the tree and changes the root hash. <span style=\"font-style: italic;\">Secondly<\/span>, it supports efficient membership and non-membership proofs.

The model is then retrained using a deterministic and documented training procedure on the modified dataset, which corresponds to a new Merkle tree with a different root hash. A zero-knowledge proof is then generated that establishes three facts: first, that the new training dataset corresponds to a specified modified Merkle root; second, that the hash of the excluded data record is not present in the new Merkle tree; and third, that the training algorithm was executed according to predefined, auditable rules on the committed dataset.

A dishonest data fiduciary might attempt to generate a proof that purports to demonstrate unlearning without actually retraining the model or might substitute a different dataset to produce a valid-looking proof while retaining the original model. The proof system must therefore bind the training computation to the committed dataset in a manner that prevents such forgery. The cryptographic commitment scheme achieves this by ensuring that the proof is valid only for a model trained on the specific dataset corresponding to the committed Merkle root. Any deviation from the committed dataset or the prescribed training algorithm would produce a different computation trace that would not satisfy the proof verification equation. Thudi and others have emphasised that forgery resistance is essential for any auditable definition of machine unlearning, as without it, the verification mechanism provides no genuine assurance.<\/span><a id=\"fnref27\" href=\"#fn27\" title=\"27.

Research on membership inference attacks shows that distinguishing a model trained with a specific data point from the one trained without it can be difficult as the statistical signal of a single data point is often smaller than the noise by the rest of the training set.<\/span><a id=\"fnref36\" href=\"#fn36\" title=\"36.
