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.

Computer Forensics

So you had a customer data security breach last weekend? Do you know you could be held liable in court for failing to implement required security procedures? That’s right. Due to the overwhelming surge in identity theft wherein nearly 20 million Americans have already been affected, most states have enacted laws to curtail this fast rising crime. Therefore, it is important to redefine how your company deals with customer data security.

  • First, you’ll want to know what your obligations are as dictated by law. Some places, for example, require the destruction or deletion of personal data through shredding, erasing, or by rendering them undecipherable.
  • Second, not only do you need to comply with the said requirements, you’ll also have to prove in court that you actually complied if ever a security breach does happen.
  • Third, you need to be aware of your post-breach duties to avoid being dealt additional penalties.

Obviously, such situations now call for individuals who are experts in both the legal and technical aspects regarding data security. Such individuals are practitioners of a relatively new discipline known as computer forensics.

Armed with our computer forensics specialists, we’ll be able to help you deal with the above concerns. As a result, you can be prevented from having to pay fines that can go up to hundreds of thousands of euros.

There are other equally important reasons why you would want to avail of computer forensics services. For example, you’ll need computer forensics specialists because you want to:

  • Catch a person involved in criminal activities such as child porn, stealing of personal data, and destroying intellectual property.
  • Investigate a computer, network, or even a mobile device for clues that may lead to the culprit.
  • Determine the extent and possible causes when you discover your digital data has been damaged.
  • Find and recover damaged, deleted or encrypted data regardless of whether the cause was intentional or not. If the data in question will be used as evidence in a legal action, there are certain procedures that need to be followed during recovery operations to retain the integrity of the data. Computer forensic specialists are highly qualified for such operations.
  • Implement security policies in your organisation. Such policies have to operate within legal bounds if you want to avoid possible sanctions in the future. These policies should also be designed such that future forensic operations can be conducted with a high likelihood of success.

That said, a company that integrates computer forensics into its IT security policies and practices will be better equipped to remedy the situation once data security has already been compromised than a company that doesn’t.

Outsourcing

Are you ready to outsource? Do you even need to outsource? We’ll help you answer those and other questions regarding outsourcing and your company.

Once we’ve determined that outsourcing will render your organisation more focused on your core competencies, more cost-effective, and more flexible, we’ll offer you the full spectrum of our services. Our specialists can assist you in every stage of the entire outsourcing life-cycle.

Starting from evaluating what can be outsourced, through finding the right outsourcing service provider, building the contract and agreements, getting everything in place, and managing the outsourcing relationship – we’ll be with you every step of the way.

Learn more about some of the outsourcing services we offer:

Outsourcing Contracts and Agreements

When an outsourcing project fails, both customer and service provider are quick to put the blame on the other party. But in most cases, the actual culprit was really just sitting there since day one – a poorly planned and implemented agreement.

We understand how costly and disruptive a failed outsourcing project can be for your business. That is why we put utmost attention to each contract and SLA (Service Level Agreement) that our customers enter into. This always reduces the likelihood of having unmet expectations, one of the major reasons why some outsourcing relationships fail.

We make sure that each agreement is fair, not only for our customers but also for the service providers themselves. Why? Because a disadvantaged provider will most likely end up delivering poor service as an offshoot of efforts to improve its profitability and ROI.

To accomplish this, we’ll thoroughly assess the infrastructure, resources, and expertise of your potential service provider to ensure they have the capability to meet your expectations. We’ll also make sure that their expectations are realistic and clear to you as well.

Here’s what you can expect from us when we start managing your outsourcing contracts and agreements:

  • A thorough assessment of your specific needs and the service provider’s profile to determine whether you have the right match before proceeding with any agreement.
  • Professional assistance when the time comes for you to discuss the scope of work, expected service levels, and when negotiating for appropriate pricing. We’ll also help you set up provisions for possible changes in the scope later on.
  • Expert counsel during drafting and finalisation of the contract and Service Level Agreements. Whenever applicable, we’ll help you propose penalties whenever service levels are not met and rewards when they are exceeded.
  • Regular reviews to determine whether everything agreed upon in the past, like pricing and service levels, are still realistic or competitive enough in view of current technological advancements and the prevailing social and economic environment.
  • Mediation expertise whenever the outsourcing project appears to be falling apart. We’ll work with you and the service provider to resolve conflicts and avoid the expensive exercise of having to terminate the contract. But if the best solution is to part ways, we’ll make sure you make an exit with the least disruption, missed opportunities and financial loss.

Application Outsourcing

I’m sure you’ve come to realise that to gain competitive advantage these days, you really need to invest in IT applications.

There are applications for enhancing your customer relationships, speeding up production, streamlining processes, advancing collaboration, protecting your systems from malware and many more. Selecting the right application, testing it, implementing it into your system, and then managing it can deviate resources which would have otherwise been used in other areas to build business value, increase profits, and enhance innovation.

Wouldn’t it be nice to unload yourself of the management processes which usually accompany IT applications? Actually, you can – through application outsourcing. Application outsourcing providers possess the expertise to either partially or fully assume responsibility of your IT applications.

Our job is to see to it that you link up with the provider who can best answer your needs. The overall proficiency of these providers spans both proprietary and opensource solutions, allowing them to cater to a wide range of preferences and budgetary limits. At the very least, they can provide professional support for well established applications.

If needed, they can develop applications for your organisation, taking charge of every step in the system development life-cycle: starting from system initiation, requirements analysis, through design, construction, acceptance and eventually to implementation.

Here are some of the benefits you can enjoy once we start managing your application outsourcing initiatives:

  • Freedom from time-consuming tasks such as installations, upgrades, configurations and repairs.
  • Reduced total cost of ownership (TCO).
  • 24/7 support from well-trained personnel. This can substantially cut downtimes caused by inexperienced troubleshooting.
  • The option to have your applications housed in more secure and reliable environments with much higher availability and much lower planned/unplanned downtimes.
  • Dedicated specialists who can focus on providing better regulatory compliance and risk mitigation initiatives.

Infrastructure Outsourcing

Keeping up with the competition nowadays usually requires technological advancements as well as the capability to manage and maintain the infrastructure that has to support them. These undertakings can suck your resources dry.

If you’re looking to reduce costs even while improving the performance of your networks, servers, databases, firewalls, desktops and mobile devices, you might want to consider IT infrastructure outsourcing among your top options. Infrastructure outsourcing service providers have the resources dedicated to a stable, secure, scalable and always available IT infrastructure.

Typical service provider facilities include data centrers equipped with high-speed networks, reliable power, dependable security, as well as provisions for upgrades, consolidation, disaster recovery, or even business continuity.

These providers employ specialists and staff who can manage and maintain all of these for you. While your provider juggles your core IT-related tasks, you can keep your eye on the ball and refocus on your company’s business goals.

Here are some of the benefits you can enjoy out of infrastructure outsourcing:

  • Freedom from time-consuming tasks such as installations, upgrades, configurations and repairs.
  • Since service providers, who are expected to have better horizontal and vertical scalability, will deal with the technological intricacies, your company’s strategic development initiatives can proceed unhampered.
  • Greatly reduced electricity expenses as a result of consolidation.
  • Easier, faster, cheaper, and more reliable disaster-recovery solutions through virtualisation.
  • Lesser risks of disruptions caused by power outages, cyber attacks, or Internet connection downtimes.

Business Process Outsourcing

With the sheer number of business processes your company has to attend to, it wouldn’t be surprising if you rarely have room to innovate.

Through business process outsourcing, we can free a considerable part of your financial and manpower resources which are currently focused on routine activities. With more resources to drive innovative initiatives, you’ll be able to accelerate production, improve customer service, enhance overall business value, and arrive at a stronger bottom line.

Some of the business processes that may be outsourced include data entry, finance and accounting, form processing, procurement, and HR, among others. If you’re interested in finding answers to the what, how, who, and where of BPO, specific to your organisation, we’ll be happy to enlighten you.

Here are some of the benefits you can enjoy once we start managing your BPO initiatives:

  • Professional guidance to ensure that your BPO undertakings will really result in substantial savings and significant improvements to your organisation’s business value.
  • Careful monitoring of service levels to ensure faster turnaround, accurate data, and high quality outputs.
  • Expert evaluation of information handling processes to guarantee full confidentiality.
  • Professional and unbiased management dedicated to establishing a strong, reliable, and fruitful relationship between you and your provider.
Spreadsheet Woes – Burden in SOX Compliance and Other Regulations

End User Computing (EUC) or end User Developed Application (UDA) systems like spreadsheets used to be ideal ad-hoc solutions for data processing and financial reporting. But those days are long gone.

Today, due to regulations like the:

  • Sarbanes-Oxley (SOX) Act,
  • Dodd-Frank Act,
  • IFRS (International Financial Reporting Standards),
  • E.U. Data Protection Directive,
  • Basel II,
  • NAIC Model Audit Rules,
  • FAS 157,
  • yes, there?s more ? and counting

a company can be bogged down when it tries to comply with such regulations while maintaining spreadsheet-reliant financial and information systems.

In an age where regulatory compliance have become part of the norm, companies need to enforce more stringent control measures like version control, access control, testing, reconciliation, and many others, in order to pass audits and to ensure that their spreadsheets are giving them only accurate and reliable information.

Now, the problem is, these control measures aren’t exactly tailor-made for a spreadsheet environment. While yes, it is possible to set up a spreadsheet and EUC control environment that utilises best practices, this is a potentially expensive, laborious, and time-consuming exercise, and even then, the system will still not be as foolproof or efficient as the regulations call for.

Testing and reconciliation alone can cost a significant amount of time and money to be effective:

  1. It requires multiple testers who need to test spreadsheets down to the cell level.
  2. Testers will have to deal with terribly disorganized and complicated spreadsheet systems that typically involve single cells being fed information by other cells in other sheets, which in turn may be found in other workbooks, or in another folder.
  3. Each month, an organisation may have new spreadsheets with new links, new macros, new formulas, new locations, and hence new objects to test.
  4. Spreadsheets rarely come with any kind of supporting documentation and version control, further hampering the verification process.
  5. Because Windows won’t allow you to open two Excel files with the same name simultaneously and because a succession of monthly-revised spreadsheets separated by mere folders but still bearing the same name is common in spreadsheet systems, it would be difficult to compare one spreadsheet with any of its older versions.

But testing and reconciliation are just two of the many activities that make regulatory compliance terribly tedious for a spreadsheet-reliant organisation. Therefore, the sheer intricacy of spreadsheet systems make examining and maintaining them next to impossible.

On the other hand, you can’t afford not to take these regulations seriously. Non-compliance with regulatory mandates can have dire consequences, not the least of which is the loss of investor confidence. And when investors start to doubt the management’s capability, customers will start to walk away too. Now that is a loss your competitors will only be too happy to gain.
