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.

Increase Customer Loyalty with Field Service Management Software

One sure way to turn off customers is to give them a disappointing experience. It cuts across the board- from plumbing jobs, electrical installation and maintenance projects, window cleaning or repair, tenants in the property you’re managing, to package delivery firms. If your customers keep witnessing delays, cancelled appointments, to oversights like double booking which end up messing their individual schedules, they are likely to stop hiring your services and seek out a competitor.?

Field service jobs are particularly prone to such blunders, especially with the traditional manual way of doing things. While smartphones and computers have been infused into the day-to-day running of businesses, it is still common to find companies relying on manual processes to schedule their appointments, track the employees providing the services, monitor the progress of the jobs and ask for status updates, to managing inventory and invoices for completed tasks. This creates a major bottleneck in operations. The Small & Medium Business Trends Report, that took responses from nearly 500 SMB owners and leaders, showed that they spend an average of 23% of each workday manually inputting data. This is time that would have otherwise been spent tending to the customers? needs. It creates a backlog of tasks, forcing the customers to wait for longer to get their issues handled.?

The inefficiencies witnessed in these traditional methods led to the advent of field service business management software. These systems come in to optimise operations and enhance your service delivery. As a business, automating your scheduling, job tracking, routing procedures and handling the invoicing, all through a single platform, greatly reduces your workload. Managing inventory, communicating with your employees out in the field through handy apps on their phone, giving them access to a database of reports and notes on the various jobs they have been tasked with – these all aid in smoothing out the sorting of tasks, and gets rid of the mounds of paperwork that would have been required.?

From Your Customer’s Perspective

When you’re facing a plumbing leak at home, electrical faults that result in power outages in the office building, damaged gas boilers that are hampering operations in the industrial plants- you want them to be addressed. Homeowners, business owners and facility managers in these situations are anxious about getting the issue resolved- yet the firm they are relying on to handle it is caught up in a logistical nightmare, boggled down by paperwork that prevents them from sending their technicians to the location. You really don’t want to hear a series of excuses about why your problem could not be addressed in time. While delays can be a nuisance, cancelled appointments are altogether exasperating. See, the customer is left in a difficult position, since the problem is not resolved, and they have to contend with having to make a subsequent appointment- of which they will not be sure if they can bank on the hired firm to deliver on its mandate. With an FSM, you get to prevent such incidents from occurring.

How Your Customers Benefit From Field Service Job Management Software

Reliable services

Firstly, the customer wants services that they can count on. When an issue arises and an appointment scheduled, they want it to be honoured. With the FSM, you get to accurately schedule the tasks, from the timing involved to assigning it to the appropriate technician, who is skilled in the task. With the automated scheduling and dispatching, the technician downtime that was previously witnessed is reduced- which has the welcome benefit of cutting down your operational costs.?

Speaking of which, the confusion that was previously seen when perusing through documents and simply calling up the first employee whose skill is similar to the job description, is avoided. Here, the field service management platform enables you to determine the most appropriate member of your workforce to handle the task. This makes them more motivated at their job, resulting in higher quality results- whether it’s an installation task, repair and maintenance project, or cleaning service for companies providing them in residential and commercial buildings.?

Get it done right the first time around

The field service scheduling software enables the technician to have all the information pertaining to the job accessible in real-time. This is availed via app– that the technicians will have on their phones. It is through this very app that they will make updates of the tasks being handled, sending in notes, photos and reports to the system. These will, in turn, be monitored at the head office all through the progress of the job, being managed through the interactive FSM dashboard.?

With the customer’s history being accessed by the technician, information that includes the specs and hazards about the particular job being handled, notes from the previous technicians who had been tasked to the building- such as the installation crew and previous repairs that had been done, will enable the personnel on the ground make well-informed decisions throughout the course of the task. Any issues that arise will also be taken note of, equipment and parts ordered through the app as well, ensuring that things proceed seamlessly. That way, the percentage of situations getting fully resolved during the first appointment increases- which translates to fewer cases of complaints being made.?

Instant invoicing

Immediately the job is done, the customer inputs their e-signature through the app, and the technician marks the task as completed, the very same FSM is used to process the invoice and send out an emailed copy to the customer. This will be an accurate invoice, without any data loss, and the customer can then proceed to make the payment through their preferred mode- from credit card payments to cash, without having to wait for hours for paperwork to be processed. All this information is securely stored on the cloud-based platform.

Creating a great first impression

Your image is a core part of your operations. Certainly, you don’t want to come off as disorganised- and your customers will be quick to note this with issues like missing records, outdated reports, lateness, and improper assigning of tasks. On the other hand, having a modern digital solution integrated into your field service operations will enable you to make a great first impression, showing the level of professionalism with which you offer your services.

Customer access

FSM platforms like FieldElite also give the customers themselves access to the system, through their own dashboard. This is particularly handy given that there are cases where the customer will have multiple jobs to be carried out- like property managers who keep on having cases of plumbing accidents, electrical faults, and cleaning service needs in the different buildings that they are in charge of.?

Through the customer portal, they will be able to make appointments, track the history of repair and maintenance jobs carried out on the property, and follow up on queries. What’s more, together with the IoT where FieldElite links to ecoVaro, one can have an interactive energy management system in place to keep accurate tabs on the energy consumption, efficiency, point out areas where repairs are needed, and have technicians come over- with the bookings being made through the FSM.

Enhance Customer Experience And Score New Business Opportunities

Customer service is a key aspect of your operations. When your customers are well tended to, with their needs being met in a timely and proficient manner, it wins you their loyalty, and they’ll be more open to sending referrals your way- growing your market share. Feedback- from testimonials on your site to the reviews on your social media handles, also aids in this- and you want to have satisfied clients who will put out a good word about your brand. By investing in field software for service businesses, you will increase your employees? productivity, monitor trends, improve communication between your head office and the technicians on the ground, all of which come together to increase customer satisfaction.

UK Government Updates ESOS Guidelines

Britain?s Environment Agency has produced an update to the ESOS guidelines previously published by the Department of Energy and Climate Change. Fortunately for businesses much of it has remained the same. Hence it is only necessary to highlight the changes here.

Participants in joint ventures without a clear majority must assess themselves individually against criteria for participation, and run their own ESOS programs if they comply.
If a party supplying energy to assets held in trust qualifies for ESOS then these assets must be included in its program.
Total energy consumption applies only to assets held on both the 31 December 2014 and 5 December 2015 peg points. This is relevant to the construction industry where sites may exchange hands between the two dates. The definition of ?held? includes borrowed, leased, rented and used.
Energy consumption while travelling by plane or ship is only relevant if either (or both) start and end-points are in the UK. Foreign travel may be voluntarily included at company discretion. The guidelines are silent regarding double counting when travelling to fellow EU states.
The choice of sites to sample is at the discretion of the company and lead assessor. The findings of these audits must be applied across the board, and ?robust explanations? provided in the evidence pack for selection of specific sites. This is a departure from traditional emphasis on random.

The Environment Agency has provided the following checklist of what to keep in the evidence pack

Contact details of participating and responsible undertakings
Details of directors or equivalents who reviewed the assessment
Written confirmation of this by these persons
Contact details of lead assessor and the register they appear on
Written confirmation by the assessor they signed the ESOS off
Calculation of total energy consumption
List of identified areas of significant consumption
Details of audits and methodologies used
Details of energy saving opportunities identified
Details of methods used to address these opportunities / certificates
Contracts covering aggregation or release of group members
If less than twelve months of data used why this was so
Justification for using this lesser time frame
Reasons for including unverifiable data in assessments
Methodology used for arriving at estimates applied
If applicable, why the lead assessor overlooked a consumption profile

Solutions to Password Overload

If only technologists had their way, passwords and PINs would have long been replaced with more innovative (and admittedly, better) security solutions. But such is not the case. Those alternative solutions, which include biometrics, smart cards, and password fobs, effective as they may be, are just way too expensive to implement.

So although passwords and PINs may not be here to stay, they certainly won’t be going away soon either.

Why keeping passwords in memory is no longer possible

A couple of decades ago, it would have been nearly impossible to crack an eight-character password using brute force. Today, however, advancements in computing power are rendering the typical passwords of the past easily decipherable, forcing us to come up with passwords that are not only much longer, but also much more complex and hence difficult to recall.

For instance, memorable words like your favourite character (e.g. ‘skywalker’) may have been acceptable then, but not anymore. Today?s security systems will encourage you to insert numbers or even other keyboard characters as a means to once again counter brute force. Hence, ‘sk5%ywa936lker@#’ may be more acceptable.

Remembering that one alone can be pretty daunting.

To further complicate matters, the number of applications that require passwords for access is much greater than before even for a single end user. Ordinary end users have to keep track of passwords for their email account, network login, workstation login, online services, and so on.

The burden is even greater for your IT admins, who have to remember a larger collection of passwords that protect business critical systems and applications. Clearly, the team in charge of your IT security will need a way to manage all these passwords.

Password management solutions

Existing password management solutions typically come in the form of software applications that store passwords. Basically, all you need to remember are your login details for the app a.k.a. the ?master password?. Once you’ve gained access inside, you can then retrieve any password you stored there.

Some of these apps are installed in portable devices like Pocket PCs, PDAs, or smartphones, which you would normally take along with you. For as long as the device stays with you, your passwords will be in safe hands. What’s more, you can retrieve them anywhere you go.

But obviously, there’s a problem. What if the device gets misplaced or stolen? Although the person who ends up with your device may not be able to gain access into the app and your passwords, neither will you. A better solution would therefore be an app that can be accessed anywhere but is not susceptible to getting lost.

Web-based password manager

A web-based password manager fits the bill. You don’t have to take it with you, but still you can access it almost anywhere. A typical web-based password manager will have all your passwords stored in a centralised, highly secure location.

If you want, you can even use your mobile password manager along with the web-based one. Ideally, your web-based password manager would have a copy of all the end-user passwords as well as the master passwords of your organisation.

With an easy to access but highly-secure web-based password manager, you no longer have to come up with passwords that (ironically) are supposed to be easy to remember but hard to crack at the the same time.

Furthermore, password managers are ideal for keeping passwords that have to be changed every-now-and-then; a requirement that’s becoming all too common in organisations bent on enforcing more stringent controls.
