Abstract: ABSTRACT The present invention discloses a Keyless Temporal–Physical Data Integrity System for generating hardware-bound, self-verifiable, and tamper-evident protected data without relying on stored cryptographic keys. The system utilizes intrinsic hardware entropy sources including Physical Unclonable Function (PUF) responses, oscillator clock drift variations, and environmental stochastic noise to generate a volatile device-specific entropy signature during data creation. A temporal phase encoder integrates high-resolution timestamp information with the fused entropy signature, and a bit-weaving processor inseparably embeds the integrity signature into the dataset through bit-level encoding operations. During verification, the system regenerates real-time hardware entropy and compares a recalculated integrity signature with the embedded signature to authenticate the data origin and detect tampering, duplication, or hardware relocation. Upon entropy mismatch, the dataset becomes unreadable or non-executable. The invention is applicable to embedded systems, IoT devices, edge computing platforms, and secure distributed environments requiring immutable hardware-bound data provenance and integrity assurance.
