Bluefin has announced the issuance of a new U.S. patent that significantly expands the application of its core device fingerprinting technology beyond the payments space. Patent No. 12,184,624 broadens the company's intellectual property to cover data security in nearly any environment where information is transmitted, reinforcing its strategy of devaluing sensitive data at the point of entry within modern, distributed architectures.
Bluefin secures U.S. Patent No. 12,184,624 for expanded device fingerprinting technology.
The patent extends data security applications beyond payments to nearly any data transmission environment.
Key constraints from the original 2016 patent are removed, increasing flexibility and scalability.
The tech validates system integrity in cloud-native, automated, and non-human (e.g., AI) environments.
It supports Bluefin's security-first approach to devaluing data at the point of entry.
The innovation aims to simplify compliance and future-proof security strategies across industries.
This new patent builds upon Bluefin's foundational 2016 patent for device fingerprinting in PCI-validated Point-to-Point Encryption (P2PE) environments. The latest iteration removes previous constraints, such as the requirement for messages to originate from a merchant or adhere to a specific format. It also simplifies verification, requiring comparison of only one subsequent message rather than continuous validation. These updates make the technology adaptable to highly distributed, cloud-native systems and automated workflows.
The evolution addresses the shift toward autonomous software and AI-driven systems. "From a technology standpoint, this patent reflects how data environments have evolved," said Tim Barnett, Chief Information Officer at Bluefin. "Systems today are highly distributed, and security must be embedded into the infrastructure itself, not layered on after the fact. By removing dependencies on specific formats or identifiers, this innovation allows fingerprint-based validation to work reliably across modern architectures without introducing friction or complexity."
The broader claims signify a strategic expansion of Bluefin's market potential, moving from a focus on payment security to a wider data security proposition. "This patent isn’t just an extension of our original work - it’s a major expansion of where and how this technology can be applied,” said Ruston Miles, Founder of Bluefin. “By broadening our claims beyond payments and rigid message structures, we’re opening the door to securing sensitive data across industries and use cases. That has real commercial impact, allowing organizations to reduce risk, simplify compliance, and future-proof their security strategies."
This patent strengthens Bluefin's growing IP portfolio focused on encryption, tokenization, and orchestration technologies. It underscores the company's commitment to innovating security models that validate not just data, but the integrity of the systems generating it, which is critical for trust in automated decision-making.
The announcement reinforces Bluefin's position as a security-first infrastructure provider, offering a foundational technology that can be applied to devalue sensitive data across a diverse range of modern digital interactions, from financial transactions to AI agent communications.
