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.

Energy Management Tips

Energy management is of interest to various stakeholders; be it heads of facilities, heads of procurement, heads of environment and sustainability, financial officers, renewable energy managers and heads of energy. Some of the energy management tips that can be used to achieve considerable energy savings are:

1) Purchasing energy supplies at the lowest possible price

2) Managing energy use at peak efficiency

3) Utilising the most appropriate technology

1. Purchasing energy supplies at the lowest possible price
Purchasing energy supplies at the lowest possible price could be the starting point to great savings of energy costs. This can be achieved through switching your energy supplier. It is always advisable for companies to always take time to compare the energy tariffs to ensure they are on the best tariff and make great savings.

2. Managing energy use at peak efficiency

(a) Free help

There are some online tools that offer energy-efficiency improvements. These could come in handy in helping someone find out where to make energy-efficiency improvements.

(b) Energy monitors

An energy monitor is a gadget that estimate in real time how much energy you’re using. This can help one see where to cut back on energy consumption.

(c) Turning down thermostats

Turning down radiators especially in rooms that are rarely used/empty rooms or programming the heating to turn off when no one is there can go a long way in saving energy and energy costs.

(d) Use energy saving bulbs

Use of energy-saving light bulbs can cut down on energy usage drastically. Replacing all the light bulbs with energy-saving ones could make significant savings on energy usage and replacement costs since energy saving bulbs also have a longer life.

(e) Switching off unnecessary lights

It is also important to switch off lights that are not in use and to use the best bulb for the size of room.

(f) Sealing all heat escape routes

It is recommended that all gaps should be sealed in order to stop heat from escaping. Some of the heat escape routes are: windows, doors, chimneys and fireplaces, floorboards and skirting and loft hatches. The ways through which this can be achieved are:

? Windows- use of draught-proofing strips around the frame, brush strips work better for sash windows

? Doors – use of draught-proofing strips for gaps around the edges and brush or hinged-flap draught excluders on the bottom of doors

? Chimney and fireplace – inflatable cushions can be used to block the chimney or fit a cap over the chimney pot on fireplaces that are not used often

? Floorboards and skirting – Using a flexible silicon-based filler to fill the gaps

? Loft hatches – the use of draught-proofing strips can help to prevent hot air escaping
It is also important to consider smaller holes of air such as keyholes and letterboxes.

3. Utilising the most appropriate technology
Utilisation of technology as an energy management tool can be by way of choosing more energy efficient gadgets and by way of running technological gadgets in an energy efficient manner.

Risk Assessment

Risk assessment is a vital component in BC (Business Continuity) planning. Through risk assessment, your company may determine what vulnerabilities your assets possess. Not only that, you’ll also be able to quantify the loss of value of each asset against a specific threat. That way, you can rank them so that assets that are most likely to cripple your business when say a specific disaster strikes can be given top priority.

However, a poorly implemented risk assessment may also cost you unnecessary expenditures. Many risk assessors are too enthusiastic in pointing out risks that, at the end of the assessment, they tend to over-appraise even those having practically zero probability of ever occurring.

We can assure you of a realistic assessment of your assets’ risks and propose cost-effective countermeasures. These are the things we can do:

  • Identify your unsafe practices and propose the best alternatives.
  • Perform qualitative risk assessment if you want fast results and lesser interruptions on your operations.
  • Perform quantitative risk assessment if you want the most accurate depiction of your risks and the corresponding justifiable costs of each.
  • Conduct frequency and consequence analysis to identify unforeseen harmful events and determine their effects to various components of your organisation and its surroundings.

How Small Irish Businesses Avoid the GDPR Sting

Accountants providing chartered accounting services and tax advice are alerting smaller Irish companies to the consequences of the pending General Data Protection Regulation (GDPR). They believe these are going to feel the most pain come 25 May 2018, if they do not implement GDPR by then. We are trying our best to help avoid this situation by providing advice.

How to Kick the GDPR Ball into Play

The Irish Information Commissioner?s Office has produced a toolkit regarding where?s best to start. They suggest beginning with an information security assessment to determine the gaps companies need to close. Once quantified, this leads naturally to a plan of action, and resources needed to fulfil it. Here?s how to go about it:

1. Start by assessing your current ability to identify, assess, and manage threats to customer data security. Have you done anything at all to date? You must be holding some customer information surely, and it is highly likely the GDPR applies to you.

2. Next, review your company?s current customer data security policies. Are they documented and approved, or do new employees discover them sitting next to Nellie? Rate yourself on a scale where ten is successful implementation.

3. Now consider how well you have pinned responsibilities on individuals to implement policies and take the lead on GDPR. The latter should be the business owner, or a board member with clout to make things happen.

4. By now, you should have a grasp of the scale of work ahead of you, remembering the EU deadline is 25 May 2018. If this sounds overwhelming, consider outsourcing to your accountant or a specialist provider.

5. Under the General Data Protection Regulation you have only 72 hours to report a breach of customer data security to the Information Commissioner?s Office. Do you have a quality assurance mechanism to oversee this?

Tangible Things to Bring Your Own People on Board

With all the changes going on, there is a risk of your employees regarding GDPR as ?another management idea going nowhere.? Thus, it is important to incorporate the new EU regulations in staff training, particularly with regard to data security generally. They may fully come on board only once they see tangible signs of progress. You should in any case put the following measures in place unless you already have them:

1. A secure area for your servers and for any paperwork your customers provided. This implies access control on a need-to-know basis to protect the information against loss, damage, and theft.

2. A protocol for storage media and record disposal when you no longer require them or something supersedes them. You are the custodian of other people?s information and they deserve nothing less.

3. Procedures to secure customer data on employee mobile devices and computers: This must extend to work done at home, at consultant sites, and by remote workers.

4. Secure configuration of all existing and new hardware to minimise vulnerability and storage media crashes. These quality assurance measures should extend to removable media and remote backups.

So Is This the Worst of the Pain?

We are at the heart of the matter, although there is more to tell in future articles. You may be almost there, if you already protect your proprietary information. If not, you may have key company information already open to malware.We should welcome the EU General Data Protection Regulation as a notice that it is time to face up to the challenges of data protection and security generally. The age of hacking and malware is upon us. The offender could be a disgruntled employee, or your competition just down the street. It is time to take precautions.
