Big Data: Fraud, Finances
Financial institutions have been working hard to implement technologies which better protect them and their customers.
Innovations such as chip and PIN have made cards more secure, while the introduction of two-factor authentication has also greatly helped.
However, none of these systems are perfect and fraud levels continue to rise in many countries.
Fortunately this is an area where big data can make a significant difference.
Fraud detection relies upon the use of both relational data and non-relational data – structured and unstructured data.
Banks know where our home branch is and they know within a standard range of incidences how often we take out money or use our cards.
They know where we work and the types of transactions we make most commonly. These known quantities form part of the fraud detection process.
The unpredictability of humans….
But the nature of human beings is that we do not always stick to the path most travelled. Consider a man buying an engagement ring. This is a perfect example of something which many people may only ever do once in their lives.
Looked at in terms of that data point it appears to be an entirely random act.
A man on the hunt for an engagement ring may never even have set foot in a jewellers shop in his life.
He will almost certainly have never spent a month’s wages on a single item of jewellery. In the world of data analysis such screaming anomalies should be cause for concern.
So why are more people not challenged when making this kind of transaction? Because it is incumbent upon banks not to leave us frustrated or without cash in our hour of need.
The man buying an engagement ring may have enough on his mind without having his card declined at the point of sale. For every transaction, a bank or a card issuer is dynamically analysing data and weighing up the risk of fraud.
The key lies of course in big data.
There are many types of data, unrelated even to the individual which can quickly be referenced – in split seconds thanks to the power with which big data is processed – from data relevant to that individual, such as past travel habits, to data relevant to the nature of the suspect transaction.
Patterns of where fraud has been conducted and past behaviours of the rightful card owner are a key element in detecting and predicting fraud, to the extent that diverse frauds can be traced quickly back to specific businesses where a rogue employee may be stealing card numbers or cloning cards.
Banks now have that reservoir of data related to fraudulent activity and quickly assess the likelihood of transactions being suspect.
Back to our hopeful man shopping for an engagement ring, he may go unchallenged because that reservoir of data shows that very few fraudsters try to conduct card fraud in jewellery shops. This may be because of high levels of CCTV coverage in such shops.
…is actually quite predictable
Believe it or not, the apparently unusual purchase of engagement rings is actually fairly predictable. Somebody may never have bought an engagement ring before, but his card issuer may see from his profile that he fits the bill of somebody due to.
A recent mortgage, an increased focus on saving, a second name appearing on a credit card, an expensive holiday in contrast to the budget breaks or golf holidays he has been on with his friends in the past, regular outlay on home furniture which suggests he is setting up home with somebody, a move from a sporadic expenditure on food to a more structured approach which suggests more nights in at home, less time spent in bars, more time in restaurants.
These are all behaviours which become powerful data points in the overall modelling of customer profiles.
He may think his purchase of an engagement ring is extraordinary and a huge step but his bank – or at least the data it holds – may have been able to tell it was coming for some time.
Ultimately, data has the ability to look at us dispassionately and non-judgmentally. We may think it outrageous that we celebrate a birthday once a year by spending over the odds on dinner at a fancy restaurant we’d never normally visit on any other day of the year.
But if this is something we only do once a year then the data barely needs to be sweated to find an answer as to whether this is fraudulent behaviour.
Once per year may seem occasional to us, or even out of character, because it is at odds to the way we behave on the other 364 days of the year, but the data sees a creature of habit.
It knows it’s our birthday – not least because our date of birth is among the relational data held about us. That fact can easily be linked to any spike in spending on that date.
Even our one-off purchases are almost certainly not as one-off as we think. Most people exercise a degree of financial caution and display behaviours our banks will be able to understand from the data they collect and analyse.
We may only buy one engagement ring in our lives but the money spent on that engagement ring will almost certainly be within a predictable parameter based on our salary, our regular outgoings and the value of our mean and median purchases and the statistical outliers we will have created with purchases such as a car or a house.
All of this means that the vast majority of our spending is reassuringly predictable.
The insights into our behaviour that big data analysis brings about provides a clear benchmark against which fraudulent activity can be rapidly identified and shut down.

World Bank Debars United Aviation Services, Owner over Fraudulent Activities

The World Bank Group has announced the 31-month debarments of United Aviation Services Limited (UNASEL), a transportation services company based in Nigeria, and Air Vice Marshal Alkali Mamu, its owner and president, “in connection with fraudulent practices under the Enhancing Niger Northeastern Connectivity Project,” according to a press release issued by the multilateral development bank.

The statement said that the project aims to enhance connectivity and road safety along the Zinder-Agadez Road section and improve access to basic socioeconomic infrastructure for selected communities in that road section.
However, according to the statement: “UNASEL and Mr. Mamu presented false experience documents in a prequalification application to qualify for a contract under the project. This was a fraudulent practice under the World Bank’s sanctions framework.”
“The debarments make UNASEL and Mr. Mamu ineligible to participate in projects and operations financed by Bank Group institutions. The debarments are part of two settlement agreements under which UNASEL and Mr. Mamu admit culpability for the underlying sanctionable practices,” it added.
The statement further said: “Per the Bank Group Sanctioning Guidelines, the settlement agreements provide for a reduced period of debarment in light of UNASEL and Mr. Mamu’s cooperation.
As a condition for release from sanction under the terms of the settlement agreements, UNASEL and Mr. Mamu commit to developing and implementing integrity compliance measures that reflect the relevant principles set out in the Bank Group Integrity Compliance Guidelines, and Mr. Mamu further agrees to complete corporate ethics training.
UNASEL and Mr. Mamu also commit to continue to fully cooperate with the Bank Group’s Integrity Vice Presidency.
“The debarments of UNA SEL and Mr. Mamu qualify for cross-debarment by other multilateral development banks under the Agreement for Mutual Enforcement of Debarment Decisions that was signed on April 9, 2010.”

NITDA Introduces Cloud Certification Boost Data Localisation Compliance

National Information Technology Development Agency (NITDA) has introduced so-called Nigeria’s Certified Cloud Register, regulatory framework developed under the agency’s National Sovereign Cloud Initiative to determine which cloud providers are authorized to handle sensitive data, such as banking records.

In effect, from October, NITDA requires banks, fintech companies and other regulated organisations to source cloud infrastructure providers from a national register of certified firms approved to host sensitive financial and government data.
The Certified Cloud Register, is expected to strengthen data sovereignty, improve regulatory oversight and support the implementation of the Central Bank of Nigeria’s (CBN) data localisation policy, which takes effect on January 1, 2027.
Under the framework, banks, fintechs, government institutions and other regulated entities will be able to verify whether cloud service providers, data centre operators, managed service providers and Artificial Intelligence (AI) infrastructure companies have met NITDA’s certification requirements before entrusting them with critical digital workloads.
The initiative is expected to provide regulated institutions with a standardised process for selecting cloud infrastructure providers that satisfy Nigeria’s technical, security and regulatory requirements.
According to NITDA, the framework establishes “a common national standard, an independent assessment process and a public register of approved providers that banks, fintechs and government institutions can rely on when selecting cloud infrastructure partners.”
The register is expected to become a key compliance tool ahead of the CBN’s directive, which requires all payment transaction data generated within Nigeria to be stored and processed locally, effective from January 1, 2027.
The policy applies to deposit money banks, microfinance banks, mobile money operators, payment service providers, switching companies and other financial institutions.
The certification regime is also expected to reshape Nigeria’s cloud computing ecosystem, making regulatory approval a major requirement for cloud providers seeking to handle sensitive data for regulated industries.
Figures cited by NITDA showed that Nigeria’s 10 largest banks spent about N177.91 billion on information technology in the first quarter of 2026, representing a 31 per cent increase over the corresponding period last year.
A sizeable portion of the investment currently supports cloud infrastructure hosted outside Nigeria, a trend the new certification framework is expected to address by encouraging greater utilisation of compliant local infrastructure.
NITDA said the certification programme will apply the same technical and regulatory standards to indigenous cloud providers and international hyperscale operators, creating a level playing field for all companies seeking to provide cloud services to regulated sectors.
The agency also disclosed that more than 85 per cent of Nigerian businesses currently rely on cloud services, with the majority using infrastructure hosted outside the country.
It said the new framework is aimed at improving confidence in Nigeria’s digital infrastructure while promoting local capacity and enhancing oversight of critical national data.
Speaking on the objective of the initiative, Kashifu Inuwa Abdullahi, director-general of NITDA, said the programme is designed to strengthen Nigeria’s position in the global digital economy rather than exclude foreign technology companies.
According to him, the initiative is intended “to redefine the terms under which Nigeria participates in the global digital economy rather than isolate the country from international technology providers.”
The Certified Cloud Register forms part of broader efforts by the Federal Government to deepen digital trust, strengthen cybersecurity and ensure that critical financial and public sector data are managed in line with Nigeria’s evolving data governance and sovereignty objectives.

Enugu State Approves Land for ITF’s Digital Fabrication Centre

Governor Peter Mbah of Enugu State, has approved the allocation of a parcel of land in Enugu, the state capital, for the establishment of a state-of-the-art Digital Fabrication Centre by the Industrial Training Fund.

Mbah announced this while receiving a delegation from the Industrial Training Fund on a courtesy visit to the Government House, Enugu.
The ITF disclosed this on Friday in a statement signed by its Director of Press and Public Relations, Thomas Ngor.
According to the statement, Mbah described the proposed project as timely and aligned with his administration’s vision of transforming Enugu into a leading destination for investment, innovation and technology-driven industrial development.
He noted that the future of economic prosperity lies in deliberate investments in human capital and emerging technologies, adding that the state has continued to create an enabling environment for innovation, enterprise and sustainable growth.
The governor explained that his administration has made technical education compulsory in the state’s basic education system, with emphasis on digital literacy, robotics and mechatronics to prepare learners for the future of work.
According to him, many traditional trades are now driven by digital technologies, making it imperative to equip young people with relevant technical competencies that will enable them to compete globally and contribute meaningfully to economic development.
Governor Mbah further disclosed that his administration has built smart schools across the state, equipped with robotics centres, mechatronics laboratories and other modern learning facilities, to prepare youths for the evolving global economy.
He noted that artificial intelligence is expected to contribute about $20tn to the global economy in the coming years.
He therefore stressed that the state must be intentional about upskilling its citizens, adding that the establishment of the ITF Digital Fabrication Centre will significantly strengthen the state’s drive to build a knowledge-based economy, foster innovation, promote local manufacturing and create employment opportunities for its growing youthful population.
Earlier, Afiz Ogun, the Director-General of the ITF, who led the delegation, said that upon his appointment by President Bola Tinubu, he was mandated to upskill Nigerian artisans to international standards.
He explained that the Fund subsequently repositioned its technical and vocational skills development efforts through strategic initiatives, including the Skill-Up Artisans Programme, which is designed to train, certify and license Nigerian artisans to international standards.
Ogun disclosed that the Fund had already established a Digital Fabrication Centre in Ikeja, Lagos, with the capacity to produce more than 400 different products. He therefore requested the allocation of land in Enugu State to establish a similar centre with the same production capacity.
According to him, the initiative is aimed at promoting industrialisation, reducing dependence on imports and preparing Nigerians for opportunities in the Fourth Industrial Revolution.
He also reaffirmed the Fund’s readiness to enter into public-private partnerships that will transform Nigeria’s artisanal ecosystem.
Ogun further noted that digital technologies, including artificial intelligence, robotics and computer-aided manufacturing, are rapidly transforming the global economy, making it imperative for Nigeria to deliberately invest in upskilling its workforce to remain globally competitive.
The ITF delegation was later conducted on a guided tour of facilities at one of the smart schools established by the Enugu State Government.
