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:

Chatbots: failure or future?

Do you know something that the entire global workforce is doing currently?

Spending more time in front of the screen- be it a laptop or phone- and interacting with brands through self-service transactions and sometimes chatbots.

For cutting-edge companies, conversational processes and interactions are becoming a dominant method of communication offered to their customers.

But, are businesses offering good conversational customer experiences?

What exactly is needed to master the art of conversational processes? As a company whose main service centres around introducing and setting up customer-facing processes for insurers, here are some crucial things we have discovered:

 

The truth about conversational processes

 

Customers value usefulness over pleasantness

This needs clearing up right off the bat: if your interaction, product, processes are not solving a customer problem, then they won’t last long no matter how pleasant they are.

To put this into practice, focus on the frictions present in the current customer journey. A classic example of this is the queueing on the phone for ages when trying to log a claim. What can you do to remove or minimize this pain point?

to control over-dreaming in this area, it’s best to adopt an MVP approach. What’s the maximum value that can be delivered with minimum effort?

It’s not just a piece of technology

As conversational interfaces are discussed within the innovation area along with the broader topic of Artificial Intelligence, the ordinary tendency is to look at them uniquely from a tech perspective - as just another SaaS product.

But, as Jeff McMillan, Chief Analytics and Data Officer at Morgan Stanley said:

‘You can create a really bad bot in ten minutes with a lot of technology today. It takes months and even years to actually do it the right way.’

At the opposite end of the spectrum is the risk of overlooking capabilities that such technologies should offer because they are overshadowed by expensive and trendy ones like NLP (Natural Language Processing).

When thinking about chatbots people tend to think about an open conversation with a robot. Whatever we ask/write to the robot, it will comprehend and answers back accordingly. This particular feature falls under the domain of NLP and represents one approach to the conversational world.

Today, NLP technology is still within the research domain (average accuracy 60-70%) and is not able to meet business and customer expectations at a sustainable price, and even less for longer and technical conversation required by customers interacting with household brands.

The point Spixii has been stressing since the beginning is that most of the time NLP is not needed from day one, especially when translating process-heavy transactions (eg. manage a claim or buying a policy) into conversational processes. In our experience, the best approach is close to the MVP concept. Instead of pushing to the market an overpromising and deceiving solution, we promote "rule-based" conversations able to deliver value from the beginning and then use data gathered through the conversations to continuously improve the process executed and the conversation itself.

 

It’s not just a matter of designing a new interaction

Often times, the temptation is to look at the conversational world uniquely from a design perspective. The focus shifts to the design of a ‘good user experience’ featuring a nice user interface and programming a conversation that customers might enjoy.

However, the primary focus should be on the analysis of current customer-facing processes and defining a new one that brings value to both the business and customer. Design is an integral part of this quest but not the only one.

 

Conclusion

AI and related technologies should be designed in collaboration with business and process owners. It’s 10% about algorithms, 20% about technology, and 70% is the business application. The latter encompasses people, processes, and a culture of change and strategy.

It’s time to switch from ‘how smart is my bot?’ to ‘how can a bot improve my business processes?’ In the first question, we are focusing on a vanity metric. In the second one, we are actually talking about critical business value.So, what are you waiting for? It’s time to create actual value for both you and your customers.
