An IoT-based
financial security system (100) for detecting malicious links and enabling secure transactions, comprising the following: a
user interface device (1) used for sending and receiving
financial transaction requests; a module (2) for detecting malicious links, configured to analyze URLs embedded in transactional communications using
machine learning algorithms trained on
phishing URL datasets and behavioral
threat patterns, compare URLs against whitelists, blacklists and
heuristic-based filters, perform a real-time URL reputation assessment and flag suspicious links; a
network security sensor (3) that is communicatively coupled with IoT devices (31) to monitor network packets and detect unauthorized traffic redirection, DNS spoofing and man-in-the-middle attacks; a transaction
authentication module (4) capable of generating multi-factor
authentication requests and verifying user identity via biometric sensors or one-time passwords (OTPs); a secure transaction routing module (5) configured to redirect legitimate financial requests to authorized servers, block
phishing attempts, and ensure
secure communication using HTTPS, TLS, and VPN protocols; and a central
control unit (6) connected to the
user interface device (1), the malicious connection detection module (2), the
network security sensor (3), the transaction
authentication module (4) and the Safe Transaction Routing Engine (5), wherein the central
control unit (6) includes a reporting unit (61) to log detected threats, transaction attempts and blocked violations and to provide real-time alerts to users and financial institutions, wherein the
system (100) secures financial transactions by detecting and neutralizing malicious connections via IoT-connected financial applications.
