Technology has moved beyond its traditional enabling role to become the major driver in the transformation of commerce. Companies that are able to accelerate innovation based on sound understanding and novel application of new and disruptive technologies will be at a distinct advantage and at the forefront of this transformation.
Visa has developed and is employing a comprehensive strategy to ensure and extend its commerce technology leadership position. This strategy in action includes the formation of Visa Research, aimed at complementing an already substantial investment in technology development with a focus on the scientific foundations of existing, emerging, and future commerce related technologies across broad time horizons. With the establishment of a formal research organization and the associated long-term commitment to technology research, Visa joins the ranks of a small number of industry leaders with both the insight and ability to substantially influence and systemically impact the future.
A paper authored by Visa Research scientist Rohit Sinha (together with UC Berkeley and MIT collaborators) has won Best Paper Award at the 2017 ACM Conference on Computer and Communications Security (CCS), the flagship security conference of the Association for Computing Machinery (ACM). The paper, titled "A Formal Foundation for Secure Remote Execution of Enclaves," formalizes hardware-based secure remote execution in a unified way for the first time and provides an accompanying software-verification methodology. This allows for provably establishing the integrity and confidentiality of software running on platforms such as Intel SGX, AMD SME, and MIT Sanctum, in turn bootstrapping trust and privacy in cloud environments.

Research projects
- Deep Learning for Commerce – develop predictive models that are essential to all parties in the payment and commerce ecosystem using advanced deep learning technologies over the financial data warehouse at Visa.
- Scalable Machine Learning System – experiment with new generations of distributed systems for machine learning applications to meet the challenge of ever increasing scale and complexity in the data processing pipeline.
- Security Analytics – enable proactive defense in our critical network and system infrastructure through continuous monitoring and real-time anomaly detection using machine learning technologies.
Security
Today's electronic payment ecosystems are possible because of a host of security technologies and capabilities that were developed over a very long and rich history of security research. Extending and enabling new ecosystems, to spur economic growth and improve the quality of life for everyone will require further advances in a number of key areas. We conduct fundamental and applied research in a number of security areas that are critical to Visa, our partners, and the world, including: mobile and distributed systems/cloud computing security, communication protocols and network security, cryptography and cryptanalysis, secure payment technologies, data and application security, malware and program analysis, user and data privacy, assurance and formal methods, security incident and event data analytics, and related fields.
Research projects
- Advances in Cryptography – aims to build on Visa’s extensive data protection capabilities to achieve policy-enforced full lifecycle cryptographic protection for data in transit, at rest, and during computation, for all computing environments and scenarios Visa employs.
- Distributed and Endpoint Systems Security – enable end-to-end secure computation, data and workload management across the distributed enterprise, between ecosystem partners, and to/from the sea of endpoints and devices
- Secure Data Acquisition and Analysis – balance advancements in cryptography and secure systems for strongest and most efficient context appropriate data acquisition, classification, protection and analysis across the computing spectrum.
Future of Commerce
Our Future of Commerce team is currently focused on understanding the fundamentals of cryptocurrencies and blockchain technology. We explore ways to advance the science of blockchain technology and enable the discovery of real-world payment use cases. We collaborate with top universities and the world’s leading blockchain researchers to develop technologies that promise to transform the financial industry in the decade ahead.

Working at Visa
Imagine working for one of the pioneers in the payment technology space. The kind of company that's been setting the bar for the way people pay and get paid for more than 50 years, and continues to innovate on a global scale. Now imagine that company is less than 10,000 employees worldwide, small enough that you'll actually have an impact and do some amazing things. Sounds pretty awesome. Well, that company exists and it's Visa.
Yep, Visa.
Imagine, in a single day, the diversity of transactions that Visa manages – from gaming enthusiasts who buy virtual goods to advance a level, to a small business merchant launching their first ecommerce business to a large consumer brand hitting their largest single-day sale. Now multiply transactions and interactions like that by millions on a global scale – that's Visa. It is a multi-billion dollar market that has experienced year over year growth!
Culture
Visa Research is a research community of scientists and engineers comprised of the most inspired and innovative thinkers and doers from across the country and around the world. We engage in fundamental and applied research, and inquisitive discussion of ideas and issues that both shape and challenge the global payments ecosystem. We foster and value a collaborative environment of inclusion that encourages dramatic results not possible when research is conducted in a vacuum.
We seek and cultivate explorers who are motivated to push the boundaries of technology beyond the conventional; to contribute to the broader innovation-driven environment at Visa, and realize the discoveries that will enable Visa, its clients and partners to solve business challenges and drive growth in digital commerce.
