Is Sound the 2FA Alternative?

In an era where online transactions, wallet providers, loyalty platforms, and ticketing platforms dominate our digital lives, ensuring robust transaction security has become an imperative. Cyber threats loom large, and the need for strong authentication methods has never been greater. Two of the leading contenders in this arena are 2-Factor Authentication (2FA) and Data Over Sound (DoS). Let's explore both these innovative security solutions, comparing their strengths and weaknesses to better understand how they safeguard our digital frontier.

2-Factor Authentication Unveiled

2-Factor Authentication is a security mechanism that adds an extra layer of protection to digital accounts and platforms. The process involves the user providing two forms of identification before granting access. Both user-friendly and versatile, 2FA can be applied across various platforms; from wallet providers to loyalty and ticketing platforms, ensuring comprehensive security for all types of digital interactions. But how secure is that comprehensive security?

What are the Vulnerabilities of 2FA?

• Phishing Vulnerability: Though stronger than single-factor authentication, 2FA is still vulnerable to phishing attacks. Crafty cybercriminals can trick users into providing their second authentication factor through clever social engineering techniques.
• Dependency on External Devices: Some 2FA methods rely on external devices like smartphones, which may not always be accessible, leading to potential issues with access for users.

How Data-Over-Sound Makes Businesses Less Vulnerable to Attack

Data over sound technology revolutionizes the way businesses facilitate transactions securely. For example, LISNR’s Radius SDK not only enables offline authentication, it also supports the transmission of one-time passwords or tokenized payloads, and can transmit encrypted payloads efficiently. By using near-ultrasonic sound waves to transmit encrypted data , users can initiate payments or transfer data seamlessly and securely between devices, ensuring a secure and efficient transaction process while reducing the risk of data interception for businesses of all types.

A Smooth and User-Friendly Experience for Wallet Providers

The use of 2FA in wallet providers typically involves a combination of something the user knows (such as a password or PIN) and something the user possesses (like a mobile device or hardware token). When a user attempts to log in or initiate a transaction, the system prompts for a second form of authentication, typically delivered to the user's registered mobile number or email address.

While 2FA enhances security by reducing the risk of unauthorized transactions and identity theft, some users might prioritize convenience over heightened security. Using sound technology, wallet providers can enjoy the benefits of a secure transactional experience , as well as an enhanced user experience with seamless transactions.

LISNR’s data over sound ecosystem aligns perfectly with a wallet provider's primary goal of providing a smooth and user-friendly experience to their customers. By eliminating the need for manual data entry, one-time passwords (OTP) or biometric scanning during transactions, users can simply bring their device within close proximity to another device using only a speaker and a microphone to complete transactions swiftly.

Additionally, unlike other payment methods that often require internet connectivity or external devices, LISNR Radius works offline and doesn't depend on specific hardware. This device independence expands the reach of wallet providers, making their services accessible even in remote or low-network coverage areas.

Bringing Contactless Access to Ticketing Platforms

Today’s transportation, ticketing, and access control companies face a major challenge. They are being forced to switch from costly germ ridden paper card systems to mobile contactless experiences . Without expensive implementation it makes it difficult to both advance consumer experience and manage fraud. But what if there was an alternative?

Data over sound provides users with faster access authentication at increased range, consistent device compatibility and reliability, and multiple entry points vs. QR code scanning or NFC. Using sound technology, mobility companies can benefit from the following:

• Contactless Ticketing: DoS offers a contactless ticketing solution, enabling users to access events, concerts, or transport services without physical tickets. By simply using their mobile devices, attendees can enter venues or board transportation with ease, reducing queues and improving overall efficiency.
• Fraud Prevention: Counterfeit tickets and fraudulent activities pose significant challenges, especially for ticketing platforms. Using data over sound to secure communication channels makes it harder for malicious actors to replicate or tamper with digital tickets, ensuring a higher level of authenticity and reducing the risk of ticket fraud.
• Real-Time Information Sharing: Ticketing platforms leverage DoS to transmit real-time information to attendees. This can include updates on event schedules, venue changes, or transportation options, keeping attendees informed throughout their journey.

Securing Loyalty Programs with LISNR

Unlike financial or sensitive platforms where 2FA is commonly implemented to enhance security, loyalty programs often have a different risk profile and purpose. Loyalty programs are designed to reward and incentivize customer engagement and brand loyalty. The primary goal is to encourage repeat purchases and build stronger connections with customers. As such, the emphasis in loyalty programs is often on convenience and user experience rather than stringent security measures.

While implementing 2FA in loyalty programs may introduce additional friction in the user experience by potentially deterring customers from participating or redeeming rewards, DoS doesn’t have this issue. Sound technology offers many benefits to loyalty programs that 2FA simply cannot, such as:

• Seamless Point Accumulation: Loyalty programs often involve the hassle of presenting physical cards or scanning QR codes to earn points or rewards. LISNR streamlines this process by enabling sound-based communication between the user's device and the loyalty platform. This allows customers to effortlessly accumulate points with a simple scan. Furthermore, LISNR’s near-ultrasonic data over sound technology offers short range, reliable 1:1 ultrasonic data transfer and authentication (SDK) between devices to facilitate a contactless transaction between a client and host device within a single foot and under.
• Enhanced Security: Security is of paramount importance in loyalty programs, as they involve the exchange of valuable customer data. DoS provides an air-gapped form of communication, reducing the risk of data breaches and unauthorized access to sensitive customer information. Security can be increased further using LISNR Radius with OTP or implementer-generated encrypted payloads.
• Increased Participation and Engagement: The user-friendly and accessible approach of DoS encourages greater participation in loyalty programs. Consumers find the process quick, effortless and secure, ultimately leading to increased customer loyalty and brand advocacy.

The Alternative to 2FA: Moving at the Speed of Life with Data Over Sound

LISNR’s near-ultrasonic data over sound technology enables proximity verification and contactless transactions (including offline data transmission), for payments and financial service providers, merchants, mobility companies, and other proximity applications worldwide. Radius can be set up and tuned to deliver one-to-one, short-range capabilities, or one-to-many long ranged data transfer exceeding 10 feet. What does this mean for your business?

The Radius SDK is engineered and developed by LISNR to communicate and authenticate data in payment, mobility, and other proximity applications using ultrasonic sound . Large retailers and smaller merchants, digital wallet providers, loyalty program managers, and mobility and ticketing platforms can revolutionize the way they operate, reduce infrastructure costs, and improve customer loyalty with data over sound.
