How to use CAPTCHA in a conversational interface?

In today's digital world, robust authentication mechanisms are an absolute necessity. With the increase in cybercrime, it is essential to protect personal and sensitive information. As stated in the last OWASP 2023 Top 10 Vulnerabilities report, authentication mechanisms are the first line of defence against unauthorized access to online accounts. Furthermore, the new ISO 27001:2022 certification standard dedicates specific controls and clauses to ensure secure authentication procedures.

A robust authentication mechanism is the key to unlocking a great number of self-services. For example, making financial operations, changing insurance policy details or consulting medical test results are operations that individuals can perform online if they pass a strong authentication screening.

However, there are situations where robust authentication mechanisms are not possible. This is the case of quote&buy journeys, where customers are not registered and identified apriori, but also when agents and advisers are about to request some actions on behalf of their clients.

In such cases, the list of self-serve services experiments a physiological reduction because some critical actions won’t be accessible to an unidentified user. Reducing the risk of robots and Denial of Services attacks is also important by using additional security measures like CAPTCHA codes and other techniques.

CAPTCHAs, in particular, are a popular security measure used to prevent automated attacks by requiring users to prove they are human and they nicely fit conversational interfaces. A handy-style text over a noisy background is generated and displayed to the user as an image. Automated Optical Character Recognition (OCR) detectors won’t be able to easily guess the keyword by reading the image.

The main three requirements for a good CAPTCHA code generator are:

Conversational Process Automation: what is it and how is it better?

3 min read

No matter the industry, you would’ve heard of chatbots. They’ve been around for four years at least. However, you might not be familiar with Conversational Process Automation (CPA), though. What is it? Let’s get right into it.

The chatbot evolution

The term ‘chatbot’ became popular a few years ago. So, people are shocked when they first hear that chatbots have been around since 1966. The first one to be made was called ‘ELIZA.’

For many years after that, chatbots remained in the shadows of the research domain. It was only in 2016 when Facebook Messenger adopted the chatbot technology that the rest of the business world opened up to them.

Since then, a proper field pertaining to chatbots has been established. It is called conversational AI: the ability to manage conversations between a human and a machine.

But let’s step back first:

A deep dive into Business Process Automation (BPA)

According to Gartner:

BPA is defined as the automation of complex business processes and functions beyond conventional data manipulation and record-keeping activities, usually through the use of advanced technologies. It focuses on “run the business” as opposed to “count the business” types of automation efforts and often deals with event-driven, mission-critical, core processes. BPA usually supports an enterprise’s knowledge workers in satisfying the needs of its many constituencies.”

The fastest emerging field within BPA is Robotic Process Automation (RPA) which UiPath defines as:

“Robotic Process Automation is the technology that allows anyone today to configure computer software, or a “robot” to emulate and integrate the actions of a human interacting within digital systems to execute a business process.”

This is where things stop for most people. Beyond the popular RPA, however, lies the field of CPA.

CPA refers to the automation of customer-facing tasks via chatbot interactions, most of the time with the chatbot integrated with core systems to allow end-to-end processing. CPA also leverages advanced analytics to continuously improve both the underlying process and the conversation with the end-user.

In this regard, CPA is the perfect marriage between the conversational world and the process automation one.

How is CPA different from other digital solutions?

Innovation has been weaved through technology so much that now there are more customer-facing solutions for better customer communication than one can implement. So, what makes CPA stand out? Let’s delve into each one succinctly.

Call centres provide an overall good and personal user experience. However, they saturate quickly causing customers to wait. No one likes waiting and complaints are inevitable then. This ultimately damages the reputation of the brand. The only way to overcome this problem would be to have one operator per customer, which is not viable business-wise. There is no space for automation here.

Webforms and portals provide a good business performance by leveraging digitisation to automate processes that were once performed manually. Yet, webforms lack the personal conversation of call centres. They reduce the interaction to a digital monologue. Customers today expect more than impersonal and clunky interactions. Essentially, there is no intelligence here.

Web live chats empower human agents to manage multiple personal conversations at the same time. It empowers and scales call centres. However, a limitation arises yet again. Each agent can manage a maximum number of 4 conversations which causes long waiting times. Thus, at their core, web live chats suffers from the same constraints as call centres; it only delays the arrival of that constraint. There is no automation or complex process here.

CPA allows the optimum customer experience by preserving the personal conversation and delivering it digitally at scale. CPA enables an unlimited number of personal and consistent conversations at a fraction of the cost of the analogue ones.
