Nowadays, 3d password technology has become one of the secure authentication methods. There are varieties of password stereotypes available for the users, such as biometric scanning, textual passwords, cards, or tokens, like an ATM. When we concern ourselves with textual passwords, it mostly follows an encryption algorithm. Whereas, biometric scanning technology is the natural signature of peoples. However, cards or tokens prove only the validity, but not the physical presence of its users.

Why have 3D passwords become essential for us?  

Today, people often dislike bringing their cards everywhere, even some of them refuse to expose their retinas under the robust IR radiations, like in biometric scanning. The problems related to the textual passwords is that they are simple to say which can easily guess out. For example, it is just like saying their girlfriend name, pet names, or any other words from the dictionary. A few years ago, Klein performed tests, and he claimed to crack 10-15 passwords in a day. Now, the passwords cracking has become a Child’s Play with the change in technology due to the fast processors and many online tools. 

3D password Introduction

In the current scenarios, when the technology has become so advanced, peoples like a 3D password for more secure authentication. 3d password technology is the more reliable and custom process that is also a fascinating way of authentication. In this technology, the passwords are created based on the fact of Human memory. As the 3D passwords depend on human memory, thus mostly it is a simple set of human’s facts so that they can quickly recall them. Human

How does a 3D password technology work?

A 3d password introduction is a simple scheme that includes following the steps of Recognition, Recalling, and then Biometrics or Token in a sequence. Once the 3d password technology implements any uses, they log in to a safe and secure website, and the 3D passwords GUI opens up. The 3D passwords GUI is an extra step of a textual password system which is required to open up GUI. Once the users go through the first authentication step, another website known as 3D virtual room displays on the user screen. It is sometimes also known as a virtual garage.

Virtual object

The 3D password technology offers a virtual environment, which contains virtual objects. In the virtual environment, the user walks and interacts with many virtual objects. 

The order and the sequence of all the user’s interaction with the placement of virtual objects that happened in the 3D environment construct the user’s 3d password. These virtual objects could be any real-life object with which we encounter every day, such as

1. A computer to type anything by the users
2. Fingerprint readers to scan the fingers of users
3. Biometric recognition devices to take the natural signatures of the users
4. Black/ whiteboard, notebooks or a piece of paper to write, draw, or sign.
5. Automated teller machines (ATM) to request a token.
6. A white light that users can switch on/off.
7. Televisions or radio to select the channels by the users.
8. A stapling machine for punching.
9. Cars for driving.
10. Books in the shelves with different sizes, editions, writers, publications and so on.
11. A set of puzzles for playing.
12. Any graphical password scheme;
13. Any other real-life objects for recognition.
14. Another future authentication scheme.
15. A set of bottles with different colours.

3D password implementation:

You can understand this technology by considering a 3D password example. Suppose, a user enters into the virtual environment, he writes something on the whiteboard. After that, he types a word on a computer that places it in the (x1, y1, z1) position. And then, he enters into a room, where he finds a fingerprint recognition device that keeps on a position x2, y2, and z2. Next, he scans his fingers to get fingerprinting. The user then goes to a virtual garage and opens the door of a car. He turns on the car radio and sets a specific channel. The sequence and the combination of all these actions toward every virtual object build the users 3D passwords.

ADVANTAGES

The most common advantages of 3D passwords are as follows:

1. 3D passwords offer more reliable security than all the existing authentication, as it is a combination of several different types of authentication scheme.  
2. It is not easy to hack a 3D password by others.
3. 3D Passwords are easy to memorize for everyone. Even if you are a short term memory loss patient, an infant child or an old person. You can remember your 3D password in the form of a story.
4. The 3D password server stores all personal details of their users as an authentication mechanism.

DISADVANTAGES

No doubt 3D password is more secure technology than other authentication methods, but still, it has few drawbacks. These disadvantages 3D password technology are as follows:

1. The use of 3D password technology is difficult for blind people.
2. 3D password requires advanced computer technology.
3. This technology is more expensive than other authentication.
4. It requires lots of programming, as it is a combination of several authentication processes.

APPLICATIONS

There are lots of applications of 3D technology, as it is a more reliable way of authentication. Here we are going to discuss a few application of 3D password technology that are often used:

1. The main application of 3D password technology is the protection of critical resources and systems. It is the combined scheme of more than one authentication technology. Thus 3D password example involves in military and nuclear facilities, missile and aeroplane guiding.
2. Several large companies use critical servers, and their security is one of the common issues for those companies. Before the 3D password introduction, peoples use simple token-based passwords or textual password protestation technologies for these servers. Now, these large companies use 3D passwords for more secure authentication to protect their critical server, as it is a multifactor technology.
3. The virtual environment is a 3D password example that uses in personal digital assistant, ATMs, desktops, computers, web, and laptop applications.
