INFYNOSPARK VERIFIED SPECIFICATION
Executive Takeaways & Architectural Key Findings
1
Raw biometric images never leave the local scanner RAM.
2
One-way hash templates cannot be reversed into original biometric images.
3
Compliant with GDPR Article 9 and Indian DPDP Act 2023 biometric protection standards.
Storing raw fingerprint images or unhashed facial vectors in a central cloud database poses unacceptable privacy and compliance risks. If a central database is compromised, biometric vectors cannot be revoked or replaced like passwords.
Physical Boundary Hashing InfynoSpark enforces cryptographic template hashing directly inside the physical terminal firmware. The raw image vector is captured, converted into a one-way mathematical signature, salted with terminal-specific hardware keys, and discarded from volatile memory before any network payload is constructed.
Cryptographic Non-Reversibility The resulting template hash is a 256-bit entropy digest. Because the original minutiae cloud points are destroyed immediately after mathematical mapping, it is mathematically impossible to reconstruct the original fingerprint or facial structure from the stored hash.
Technical Implementation Snippet
// On-Terminal Hardware Template Hashing (C++)
std::string HashBiometricMinutiae(const std::vector<uint8_t>& rawVector, const std::string& terminalSalt) {
SHA256_CTX sha256;
SHA256_Init(&sha256);
SHA256_Update(&sha256, rawVector.data(), rawVector.size());
SHA256_Update(&sha256, terminalSalt.c_str(), terminalSalt.length());
uint8_t hash[SHA256_DIGEST_LENGTH];
SHA256_Final(hash, &sha256);
return BytesToHexString(hash, SHA256_DIGEST_LENGTH);
