Abstract: Abstract A IoT data integrity verification system is disclosed for use in a IoT environment in which sensor data is transmitted through gateways to edge or cloud services. The system comprises a processor, memory, a communication interface, an input acquisition module, a preprocessing module, an analysis engine, and an output control module. The communication interface receives IoT sensor readings, device identifiers, timestamps, message hashes, gateway signatures, and ledger verification records. The preprocessing module validates and normalizes received input records before the analysis engine performs IoT data integrity verification using stored rules, profiles, policies, model parameters, or reference records. The output control module compares a generated decision value with a stored threshold or policy condition and generates integrity verification signals, accepted data records, rejected data records, ledger entries, and integrity alerts. The system stores an audit record linking source identity, validation state, decision value, and selected output action.
