Banks hold some of our most sensitive information. Every transaction, loan application, and account balance tells a story about their customers\u2019 lives. Under GDPR and banking regulations, protecting this information isn\u2019t optional \u2013 it\u2019s essential.<\/p>\n

Yet banks also need to understand how customers use their services to serve them better. The solution lies in understanding different types of banking data and how to handle each responsibly. From direct customer interactions to market research, each data source serves a specific purpose and requires its own privacy controls.<\/p>\n

Before diving into how banks can use each type of data effectively, let\u2019s look into the key differences between them:<\/p>\n\n\n\n\n\n\n\n\n
Data Type<\/th>\nWhat It Is<\/th>\nBanking Example<\/th>\nLegal Considerations<\/th>\n<\/tr>\n<\/thead>\n
First-party<\/td>\nData from direct customer interactions with your services<\/td>\nTransaction records, service usage patterns<\/td>\nDifferent legal bases apply (contract, legal obligation, legitimate interests)<\/td>\n<\/tr>\n
Zero-party<\/td>\nInformation customers actively provide<\/td>\nStated preferences, financial goals<\/td>\nRequires specific legal basis despite being voluntary; may involve profiling<\/td>\n<\/tr>\n
Second-party<\/td>\nData shared through formal partnerships<\/td>\nInsurance history from partners<\/td>\nMust comply with PSD2 and specific data sharing regulations<\/td>\n<\/tr>\n
Third-party<\/td>\nData from external providers<\/td>\nMarket analysis, demographic data<\/td>\nRequires due diligence on sources and specific transparency measures<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

What is first-party data?<\/h2>\n

\"Person

First-party data reveals how customers actually use your banking services. When someone logs into online banking, withdraws money from an ATM, or speaks with customer service, they create valuable information about real banking habits.<\/p>\n

This direct interaction data proves more reliable than assumptions or market research because it shows genuine customer behaviour. Banks need specific legal grounds to process this information. Basic banking services fall under contractual necessity, while fraud detection is required by law. Marketing activities need explicit customer consent. The key is being transparent with customers about what information you process and why.<\/p>\n

Start by collecting only what you need for each specific purpose. Store information securely and give customers clear control through privacy settings. This approach builds trust while helping meet privacy requirements under the GDPR\u2019s data minimisation principle<\/a>.<\/p>\n

What is zero-party data?<\/h2>\n

\"A

Zero-party data emerges when customers actively share information about their financial goals and preferences. Unlike first-party data, which comes from observing customer behaviour, zero-party data comes through direct communication. Customers might share their retirement plans, communication preferences, or feedback about services.<\/p>\n

Interactive tools create natural opportunities for this exchange. A retirement calculator helps customers plan their future while revealing their financial goals. Budget planners offer immediate value through personalised advice. When customers see clear benefits, they\u2019re more likely to share their preferences.<\/p>\n

However, voluntary sharing doesn\u2019t mean unrestricted use. The ICO\u2019s guidance on purpose limitation<\/a> applies even to freely shared information. Tell customers exactly how you\u2019ll use their data, document specific reasons for collecting each piece of information, and make it simple to update or remove personal data.<\/p>\n

Regular reviews help ensure you still need the information customers have shared. This aligns with both GDPR requirements and customer expectations about data management. By treating voluntary information with the same care as other customer data, banks build lasting trust.<\/p>\n

What is second-party data?<\/h2>\n
