MUMBAI, India, June 16 -- Intellectual Property India has published a patent application (202611054120 A) filed by Graphic Era, Dehradun, Uttarakhand, on April 28, for 'blockchain-anchored incremental merkle password vault system.'
Inventor(s) include Rishi Dhama; Prof. Mohammad Wazid; Saksham Mittal; and Prof. Bhaskar Pant.
The application for the patent was published on June 5, under issue no. 23/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a secure password management system comprising a client device (101) configured to derive a cryptographic key from a master password and encrypt credential data, a server (103) configured to store encrypted credential data, and a Merkle tree engine (105) configured to assign deterministic leaf indices and construct a Merkle tree of hashed credentials. The Merkle tree engine performs incremental updates by recomputing nodes along an update path (204) to generate a root hash (301). A batching module accumulates update events (401) and anchors the root hash based on a predefined condition (403) to a blockchain network (106) as an anchored root (404). The client device reconstructs the Merkle tree, computes a local root hash, and compares it with the anchored root to detect tampering, rollback, deletion, or unauthorized modification, thereby enabling efficient integrity verification with reduced computational and transaction overhead."
