The Better Way of Applying Benford’s Law for Fraud Detection

Applying Benford’s Law on large collections of data is an effective way of detecting fraud. In this article, we?ll introduce you to Benford’s Law, talk about how auditors are employing it in fraud detection, and introduce you to a more effective way of integrating it into an IT solution.

Benford’s Law in a nutshell

Benford’s Law states that certain data sets – including certain accounting numbers – exhibit a non-uniform distribution of first digits. Simply put, if you gather all the first digits (e.g. 8 is the first digit of ?814 and 1 is the first digit of ?1768) of all the numbers that make up one of these data sets, the smallest digits will appear more frequently than the larger ones.

That is, according to Benford’s Law,

1 should comprise roughly 30.1% of all first digits;
2 should be 17.6%;
3 should be 12.5%;
4 should be 9.7%, and so on.

Notice that the 1s (ones) occur far more frequently than the rest. Those who are not familiar with Benford’s Law tend to assume that all digits should be distributed uniformly. So when fraudulent individuals tinker with accounting data, they may end up putting in more 9s or 8s than there actually should be.

Once an accounting data set is found to show a large deviation from this distribution, then auditors move in to make a closer inspection.

Benford’s Law spreadsheets and templates

Because Benford’s Law has been proven to be effective in discovering unnaturally-behaving data sets (such as those manipulated by fraudsters), many auditors have created simple software solutions that apply this law. Most of these solutions, owing to the fact that a large majority of accounting departments use spreadsheets, come in the form of spreadsheet templates.

You can easily find free downloadable spreadsheet templates that apply Benford’s Law as well as simple How-To articles that can help you to implement the law on your own existing spreadsheets. Just Google “Benford’s law template” or “Benford’s law spreadsheet”.

I suggest you try out some of them yourself to get a feel on how they work.

The problem with Benford’s Law when used on spreadsheets

There’s actually another reason why I wanted you to try those spreadsheet templates and How-To’s yourself. I wanted you to see how susceptible these solutions are to trivial errors. Whenever you work on these spreadsheet templates – or your own spreadsheets for that matter – when implementing Benford’s Law, you can commit mistakes when copy-pasting values, specifying ranges, entering formulas, and so on.

Furthermore, some of the data might be located in different spreadsheets, which can likewise by found in different departments and have to be emailed for consolidation. The departments who own this data will have to extract the needed data from their own spreadsheets, transfer them to another spreadsheet, and send them to the person in-charge of consolidation.

These activities can introduce errors as well. That’s why we think that, while Benford’s Law can be an effective tool for detecting fraud, spreadsheet-based working environments can taint the entire fraud detection process.

There?s actually a better IT solution where you can use Benford’s Law.

Why a server-based solution works better

In order to apply Benford’s Law more effectively, you need to use it in an environment that implements better controls than what spreadsheets can offer. What we propose is a server-based system.

In a server-based system, your data is placed in a secure database. People who want to input data or access existing data will have to go through access controls such as login procedures. These systems also have features that log access history so that you can trace who accessed which and when.

If Benford’s Law is integrated into such a system, there would be no need for any error-prone copy-pasting activities because all the data is stored in one place. Thus, fraud detection initiatives can be much faster and more reliable.

How SOA can help Transformation

Undoubtedly, today’s business leaders face myriad challenges ranging from fierce market competition to increasing market unpredictability. In addition, the modern consumer is more informed and in control of what, where and how they purchase. Couple these challenges with effects of globalization, and you will appreciate that need for business transformation is more of a necessity than a privilege.

As recent business trends show, top companies are characterized by organizational and operational agility. Instead of being shaken by rapid technological changes and aftershocks associated with market changes, they are actually invigorated by these trends. In order to survive in these turbulent times, business leaders are opting to implement corporate transformation initiatives to develop leaner, more agile and productive operations. In line with this, service oriented architecture (SOA) has emerged as an essential IT transformation approach for implementing sustainable business agility.

By definition, service oriented architecture is a set of principles and techniques for developing and designing software in form of business functionalities. SOA allows users to compile together large parts of functionality to create ad hoc service software entirely from the template software. This is why it is preferred by CIOs that are looking to develop business agility. It breaks down business operations into functional components (referred to as services) that can be easily and economically merged and reused in applicable scenarios to meet evolving business needs. This enhances overall efficiency, and improves organizational interconnectivity.

SOA identifies shortcomings of traditional IT transformation approaches that were framed in monolithic and vertical silos all dependent on isolated business units. The current business environment requires that individual business units should be capable of supporting multiple types of users, multiple communication channels and multiple lines of business. In addition, it has to be flexible enough to adapt to changing market needs. In case one is running a global business enterprise, SOA-enabled business transformation can assist in achieving sustainable agility and productivity through a globally integrated IT platform. SOA realizes its IT and business benefits by adopting a design and analyzing methodology when developing services. In this sense a service consists of an independent business unit of functionality that is only available through a defined interface. Services can either be in the form of nano-enterprises or mega-enterprises.

Furthermore, with SOA an organization can adopt a holistic approach to solve a problem. This is because the business has more control over its functions. SOA frees the organization from constraints attributed to having a rigid single use application that is intricately meshed into a fragmented information technology infrastructure. Companies that have adopted service oriented architecture as their IT transformation approach, can easily repurpose, reorganize and rescale services on demand in order to develop new business processes that are adaptable to changes in the business environment. In addition, it enables companies to upgrade and enhance their existing systems without incurring huge costs associated with ‘rip and replace’ IT projects.

In summary, SOA can be termed as the cornerstone of modern IT transformation initiatives. If properly implemented great benefits and a sharp competitive advantage can be achieved. SOA assists in transforming existing disparate and unconnected processes and applications into reusable services; creating an avenue where services can be rapidly reassembled and developed to support market changes.

Understanding Carbon Emissions

Carbon emission is one of the hottest issues in the world of energy and environment today. While it is supposedly an essential component of the ecosystem, it has already become a large contributing factor to climate change. Carbon emission might be good but abuse of this natural process has made it harmful to people across the globe.

This series of articles aims to help people understand the intricacies of carbon emission and what society can do to efficiently manage this natural occurrence.

Natural Carbon Cycle

Two important elements in the carbon cycle are carbon, which is present in every living thing all over the world; and oxygen, which is found in the air that people breathe. When these two bond together, they create a colourless and odourless greenhouse gas known as carbon dioxide, which is then crucial to trapping infrared radiation heat in the atmosphere and also for weathering rocks.

Carbon is not only found in the atmosphere of the earth. It is also an element found in oceans, plants, coal deposits, oil and natural gas from deep down the earth?s core. Through the carbon cycle, carbon moves naturally from one portion of the earth to another. Looking at this scenario, one can see that the natural carbon cycle is a healthy way to release carbon dioxide into the air in order to be absorbed again by trees and plants.

Altered Carbon Cycle

The natural circulation of carbon among the atmosphere is vital to humankind. However, studies show that humans misuse this natural cycle and abuse it instead. Whenever people burn fossil fuels such as coal, oil and natural gas, they produce carbon dioxide ? which is an excess addition to the natural flow of carbon in the environment. The problem is that the release of carbon dioxide is much more than what plants and trees can re-absorb. People are not only adding CO2 to the atmosphere, they are also influencing the ability of natural sinks, such as forests, to remove it from the atmosphere. Humans alter the carbon cycle by contributing doubled or tripled greenhouse gas to the atmosphere, faster than nature can ever eliminate. Worst, nature?s balance is destroyed.

The Result

Greenhouse gases include carbon dioxide, methane, nitrous oxide, fluorinated gas and other gases. Although these gasses contribute to climate change, carbon dioxide is the largest greenhouse gas that humans emit. The reason why people talk about carbon emissions most, is because we produce more carbon dioxide than any other greenhouse gas.

The increasing amount of carbon emissions cause global warming to become more evident. All the extra carbon dioxide causes the earth?s overall temperature to rise as well. As the temperature increases, climate also changes unpredictably. Flood, droughts, heat waves and hurricanes are now widely experienced even in places where these phenomenon never used to happen.

To be able to reduce the risk of more severe weather conditions means burning less fossil fuels and shifting more to renewable sources. This is never easy. But, definitely, it’s worth a try.
