Zombie Delete is a cryptographic software platform that generates verifiable proof of data deletion for regulated organizations.

Key features and functions include:

Cryptographically Verifiable Deletion Receipts
Issues independent proof, referred to as a Cryptographically Verifiable Deletion Receipt (CVDR), that a specific record was deleted from a named dataset at a named time.

Tombstone Mechanism
Uses a "Tombstone" mechanism intended to prevent deleted data from being re-written or re-ingested, including into AI or LLM systems.

Merkle Tree Deletion Receipts (MKT Delete)
Generates Merkle Tree-based receipts that show what was deleted and when, using cryptographic fingerprints of the data taken before and after deletion.

Data-Out-of-Path Verification
Does not access customer data directly; instead verifies deletion events and issues receipts, which can be shared with and independently verified by auditors, regulators, or counterparties without access to the platform or the customer's systems.

Cryptographic Standards
Generates receipts using body hash, Merkle transitions, and Ed25519 signatures verified against deployment keys.

Deployment Flexibility
Runs on enterprise servers, in a customer's own environment, or on supported blockchains.

Compliance Coverage
States alignment with deletion-related obligations under GDPR Art. 17, UK GDPR, the EU AI Act, California's DELETE Act, India's DPDP, China's PIPL, Brazil's LGPD, HIPAA, BIPA, NIST SP 800-88r2, ISO/IEC 27555, and IEEE 2883, among other data protection regimes.
