The research presents a novel protocol for remote verification of data outsourced to third-party storage. The protocol aims to verify the possession of data in potentially untrusted storage without downloading. We identified challenges in existing proof-of-possession protocols (PDP) by conducting a comprehensive literature review. We stated the optimal threshold for the minimal communication cost needed in existing PDP protocols to ensure the validity of the target percentage of data blocks while maintaining high confidence. Building on these findings, we propose our own PDP requires a fixed amount of communication and offers practically deterministic validity guarantees based on the security of cryptographic hash functions. We show a scenario for monetization in both cloud-native and blockchain environments to incentivize storage providers. A rigorous security analysis demonstrates resilience against forgery attacks aimed to falsify integrity checks or compromise verifiability assumptions. Our protocol significantly reduces communication overhead compared to existing solutions while eliminating the cheating probability to negligible levels.
