Patent attributes
A method and system are described for secure communication. The system receives a first secure protocol data packet during an authenticated session to communicate with a user computing device using a secure protocol. The encrypted linked data in first secure protocol data packet is decrypted using a secure key that is dependent on encrypted linked data and user credentials. The system retrieves a second secure protocol data packet from a distributed ledger network that is associated with first secure protocol data packet. The encrypted linked data in second secure protocol data packet is decrypted. The system identifies changes between decrypted linked data of first secure protocol data packet and decrypted linked data of second secure protocol data packet and if changes are identified then first secure protocol data packet is considered as tampered and actions in first secure protocol data packet are not executed, thereby preventing fraudulent execution of transactions.
