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.

ESOS What is the Truth?

When the UK administration introduced its ESOS Energy Savings Opportunity Scheme reactions from business people followed a familiar theme.

  • Do nothing it will go away
  • The next Westminster will drop this
  • Another stealth tax. I don’t have time for this
  • Give the problem to admin and tell them to fix it

ecovaro decided to share three facts with you. These are

(1) ESOS is not a government money spinner

(2) all major political parties support it, and

(3) it is a cost-effective way to put money back in your pocket while feeling better about what business pumps into the environment.

Four More ESOS Facts

1. You Cannot Give the Problem to Admin ? Energy is technical. The lead belongs with your operations staff because they understand how your systems work. Some things are best outsourced though. ecovaro is here to help.

2. ESOS is Not Going to Go Away ? A company inside the regulation net must submit its first report by 6 December 2015. Non-compliance risks the following penalties:

  • ?5,000 for not maintaining adequate records
  • ?50,000 for not completing the assessment
  • ?50,000 for making a false or misleading statement

3. The Employee Count is the Annual Average – The employment criteria (unlike balance sheet and turnover) is the monthly average of full and part-time employees taken across the full financial year. The fact you have <250 employees in December 2015 when the first report is due does not necessarily let you off the hook.

4. The 6 December 2014 Report is No Big Deal ? When you think about it the administration is hardly likely to spend years wading through 9,000 detailed company energy plans. It has no authority to comment in any case. All that is required is for a senior director to confirm reading the document, and a lead assessor to agree it complies with the law.

Does this mean that ESOS is a damp squib? We do not think so, although some firms may take the low road. ecovaro believes the financial benefits will carry the process forward, and that the imperative to make the world a better place will do the rest.

Saving Energy Step 3 ? Towards a Variable Energy Bill

Do you remember the days when energy was so cheap we paid the bill almost without thinking about it? Things have changed and we have the additional duty of reducing consumption to help save the planet. This is the third article in our mini-series on saving energy. It follows on from the first that explored implementing a management system, and the second listing practical things to implement on the shop floor. These open up the possibility of the variable energy bill we expand on as follows.

If ?variable energy bill? sounds strange to you, I used the unusual turn of phrase to encourage you to view things in a different light. We need to move on from the ?pie chart? mentality where we focus on the biggest numbers like materials, facilities and labour, and zoom in on energy where we can achieve similar gains faster with less pain. But first, we need to see beyond the jargon that governments and consultants love, and get to grips with the reality that we can vary our energy bill and bring cost down.

As executives we recognise this, although other pressures distract us from accepting it as a personal goal. And so we delegate it down the organisation to a level where it becomes ?another crazy management idea? we have to follow to stay out of trouble. I read somewhere that half the world?s organisations do not have energy as a defined objective to monitor in the C Suite. No wonder commerce is only pecking away at energy wastage at a rate of 1% per year.

Find out where you are ?spending energy? and relate this to your core business. If there are places where you are unable to make a connection, challenge the activity?s right to exist. Following the energy trail produces unexpected benefits because it permeates everything we do.

  • Improved product design reducing time spent in factory
  • Streamlined production schedules reducing machine run times
  • Less wear on equipment reducing costly maintenance
  • A more motivated workforce that is prouder of ?what we do?

As you achieve energy savings you can pass these on in terms of lower prices and greater market share. All this and more is possible when you focus on the variables behind your energy bill. Run the numbers. It deserves more attention than it often gets.

Web Analytics

There’s a vast ocean of raw customer data on the Web. Ever thought of the implications if somehow you could harness all that data and transform it into useful information? Information that perhaps you can use in your SEO (Search Engine Optimisation) and conversion optimisation?
