A new paradigm for user authentication and device authentication

Based on the world’s first one-way dynamic authentication technology, one-time authentication code (OTAC) originally invented by swIDch provides more secure authentication by uni-directional dynamic token ONLY to overcome bi-directional limitations including high dependency on push & pull system of network connectivity between clients and servers. By reinventing authentication, swIDch sets a new standard for authentication in cybersecurity beyond the limitations of existing authentication methods.

What we face

A cyber-attack takes place somewhere around the world
once every 39 seconds. As a result, there were 8 billion pieces
of sensitive personal information being leaked to the market in 2019.
These all cost the global economy a staggering $2.9M
every minute in 2020. But WHY does this happen?
what face
Risk of static
Card numbers, ID, password, and PINs which we use every day are great examples of static information used as authentication credentials. Knowledge-based authentication – whether with PINs, passwords, passphrases – not only causes a major headache for users, but is also costly to maintain. As the world gets more connected, using static information for authentication carries with it a huge vulnerability allowing cyber crimes such as identity theft, card-not-present fraud, and hijacking to take place.
- Static information
- Easily lost and stolen
authentication process
OTP, which is widely used for secure identity authentication, cannot perform user authentication alone, so an initial authentication step (usually ID and password) is required. Since you must go through more than one authentication step, the complexity feels even greater for users.
- On its own, it is not enough to identify a user.
- It always requires initial self-authentication between a user and a server.
connection distress
In locations with poor network,
it is a big headache to force the use of a communication network for authentication. The token method is used in numerous authentication environments and has become one of the most common ways of performing secure authentication by obtaining access rights through a specific point-in-time comparison of the authentication key generated by a token service operator (TSP). This is limited due to the reliance of connectivity between a user, a server and a TSP. It is also only operates in an environment controlled by a central server.
- Requires network connection
- Bi-Directional

What we offer

swIDch’s OTAC technology combines advantages of the three most common authentication
systems – user ID/passwords, RSA hardware/software for generating authentication codes, and tokenisation.
This provides a solution that is more efficient and more effective than any of these elements individually.
It generates a single dynamic code that both identifies and authenticates the user at the same time and
can do so without a network connection. And because it’s a single-use, time-based code that’s unique to the user,
it can’t be used by someone else or used again.
Strong security
OTAC completes stronger security by generating dynamic authentication codes even in an off-the-network environment.
Seamless Integration
Use of API/SDK to bring simple and frictionless integration for IT admins.
Unlimited scalability
& flexibility
The lightness of OTAC enables applications in multiple industries and not limited to devices
cost saving
No need to build heavy token infrastructure. Save costs associated with network traffic, maintenance, and fraud compensation.
High risk of information breach with static information
Difficult to identify/authenticate the user with OTP alone
High dependency on push & pull system of network connectivity between clients and servers
Duplication-free dynamic code authentication prevents from various breach risks
Identify and authenticate the user with dynamic codes alone
Dynamic code generation without network connectivity

How it works

To access a system using OTAC, authorised users can use their mobile device. Also, other devices can be added for an extra layer of security such as an employee ID or bank card enabled with OTAC. By launching the swIDch app or the client’s own app integrated with OTAC, and then tapping the ID or bank card to the mobile device, users can generate a one-time alphanumeric or QR code.

In effect, the user’s device acts like a token server, generating a one-time code for access without the need to connect to networks. Identification and authorisation are then both enabled when users insert or scan their code into the system they want to access.

Where to use


OTAC technology can generate dynamic virtual card details without a network
connection, thereby adding an extra layer of security to the payment process.
This patented technology is a CNP (card not present) fraud prevention solution that replaces
static card information with dynamic details, which gives users full control
over their security and finance.

Connected Car

Current digital key solutions require network connectivity when it comes to car sharing to
receive and activate the key. There can be an issue when the vehicle is located
in a basement or rural area where network connectivity is weak.

OTAC allows drivers to access a vehicle in a networkless environment.
No matter where the driver or car is located, there are no obstacles for drivers activating the
digital key and sharing it with an authorized person.

OTAC is unidirectional authentication technology that allows devices to simply
authenticate your user/object with the dynamic code. Enable your users to locally generate
OTAC and deliver it over various channels such as voice, keypad, Bluetooth, etc.
Algorithm size under 4KB fits into any device chips for enhanced security.
Enterprises are moving towards microservice environments implemented with
end-to-end trust. However, authentication flows can be cumbersome and involve many
round-trips, with an irreducible time cost for each; authorisation services can become
overwhelmed as each microservice relies on them for access control.
OTAC allows secure authentication of a user in a single ended flow,
greatly reducing the number of round trips.
ICAM / Enterprises

Forget passwords and OTPs. Users can securely access services by generating OTAC
even in an off-the-network environment. With OTAC, access your company applications
anywhere and anytime. As long as OTAC guarantees hassle free log-in, remote
working is no longer a problem.

In the middle of a battle in a war, it is very difficult to identify your friendlies or targets.
Current solution to the problem is to identify friendlies from their devices
using static information, which can be hacked and used by the enemy.
OTAC can completely eliminate this risk by generating dynamic codes locally
without a network. Wherever a soldier is located, their device will send a dynamic
code which hackers cannot steal so that their own force can identify securely.
