PASSWORD:- • A password is a secret word used for user authentication to prove identity or access approval to gain access to a resource. • In modern times, username and passwords are commonly used by people during a login process that controls access to protected computer operating systems, mobiles phones, cable TV decoders, automated teller machines (ATMs), etc.

TYPES OF PASSWORD:- • Random password • Common password

RANDOM PASSWORD • Random password:-An easy to remember password, which is based on a pass-phrase that is important to you, the user. • This phrase can be a set of words taken from a book, a song, a quotation, a statement, or anything else that you always easily remember. • No one else should ever think about attributing it to you. • E.G: pass-phrase: “four score and seven years ago our fathers” • Password: “Fs&7yA0F”.

COMMON PASSWORD • Easy to remember password, which is based on a combination of two unrelated words with a mixed case of letters, numbers and symbols. • E.G: pass-words: “funny bone” • Password: “phnyb0ne”.

ADVANTAGES AND DISADVANTAGES • Can only be accessed by the owner of the site. • A password protected website. • Password may protect files, folders and documents. • Disadvantages:- • If you don’t have strong server security, someone can break into the database and read the password.

INTRODUCTION • Commonly used authentication schemes are textual passwords, graphical passwords and biometrics. • 3D password is a multifactor authentication scheme. • To be authenticated, were 3D virtual environment. • Combines recognition, recall, token, and biometrics-based systems. • Users choice to select the type of authentication technique.

3D PASSWORD • It is a multi factor authentication scheme. • It is not only based on recall and recognition. • It is the combination of recall, recognition, biometrics as well as token-based authentication schemes. • It is also known as 3 dimensional virtual environment. • It contain any virtual object.

VIRTUAL OBJECTS ARE: • A computer with which user can type. • A fingerprint reader that requires the user’s fingerprint. • An ATM machine that requires a smart card and PIN. • A light that can be switched ON/OFF. • A television or radio where channels can be selected. • A car that can be driven. • A paper or a whiteboard that a user can write, sign, or draw on.

AUTHENTICATION SCHEMES • KNOWLEDGE BASED • Recall based • Recognition based • TOKEN BASED e.g. : smart card

BIOMETRIC BASED • Fingerprint ,palm prints ,hand geometry ,face recognition • GRAPHICAL PASSWORDS • Picture based.

FUNCTIONALITIES REQUIRED • New scheme should combine the existing authentication schemes • Freedom to select the type of authentication technique. • Should provide secrets that are easy to remember ,difficult to guess.

3D passwords-Advanced Authentication Systems

The increase in the usage of computer systems has given rise to many security concerns. One of the major security concern is authentication , which is the process of validating who you are to whom you claimed to be.

Current authentication systems suffer from various weaknesses. People usually use textual passwords; however they do not follow their requirements.The issue is that users intend to use meaningful words from the dictionary, which eventually are easier to break and vulnerable to attack.

A major drawback of the textual password is its conflicting requirements- the selection of a password that is easy to remember(for the user), and at the same time, hard to guess(to prevent unauthorized access to private data).

As a solution, many biometric authentications have been proposed. These include:

However, users usually tend to resist biometrics because:

• because of their effect on privacy and their intrusiveness.
• moreover, biometrics cannot be revoked.

3D password is a multi factor authentication scheme, that is, it is a security approach that requires the user to provide more than 1 identity factor before accessing their data.

Some factors include:

• what a user KNOWS: that is their password.
• what a user HAS: that is a smart card/hard token.
• what a user IS: that is a retinal scan/ finger print.

To be authenticated into a secure system, we present a 3-D virtual environment where the user navigates and interacts with various objects. The sequence of actions and interactions towards the objects inside the environment.Then the user’s password is constructed. The password can combine most existing authentication schemes, i.e., graphical and textual passwords and various biometrics into a virtual 3D environment.

The design of the 3D virtual environment and the type of objects selected determine the 3D password key space.

Advantages:

• easy to remember and is highly secure.
• easy to customise.
• difficult to share.
• 3D graphical password has no limit.

Disadvantages:

• difficult to use for the blind people.
• requires complex computer technology.

3D passwords-Advanced Authentication Systems

Introduction.

As world continues to grow more digital, need for secure and robust authentication systems becomes increasingly important. Passwords have been traditional method of authentication, but with rise of hacking and other cyber crimes, new authentication methods are needed. One such method is 3D passwords, an advanced authentication system that combines multiple factors for enhanced security. This article will explore concept of 3D passwords, its advantages and disadvantages, and some examples of their usage.

What are 3D Passwords?

3D passwords are a new type of authentication system that adds an extra layer of security to traditional password-based systems. They are based on idea that humans can recognize and remember 3D shapes more easily than a traditional password. 3D passwords typically require user to input a combination of gestures, biometrics, and text-based passwords. For example, a user might be required to draw a particular shape in a 3D space, input a password, and then scan their fingerprint for biometric authentication.

Advantages of 3D Passwords

More secure.

3D passwords are more secure than traditional passwords because they are difficult to guess or hack. Since the 3D password consists of three different authentication factors, it makes it more challenging for hackers to gain access to the user's account.

User-friendly

3D passwords are user-friendly because users can create a password based on their preference. They can create a password using a 3D object that is easy for them to remember.

Prevents phishing

3D passwords prevent phishing attacks because the user needs to interact with the 3D object to authenticate themselves. It makes it difficult for hackers to replicate the user's password and gain access to their account.

Reduces shoulder surfing

3D passwords reduce shoulder surfing because the user needs to interact with the 3D object to authenticate themselves. It makes it difficult for anyone to see the user's password.

Disadvantages of 3D Passwords

Not widely adopted.

3D passwords are not widely adopted as other authentication techniques like biometric and multi-factor authentication.

Training required

Users need to be trained on how to use 3D passwords. It can be challenging for some users to remember the 3D object they used as their password.

Not suitable for all applications

3D passwords are not suitable for all applications. Some applications require a high level of security, and 3D passwords may not be able to provide that level of security.

Examples of 3D Password Usage

There are several examples of 3D password systems being used in various industries.

One such system is 3D gesture-based password system developed by Samsung for their Galaxy S4 phone. This system allows users to input a combination of swipes, taps, and other gestures to unlock their phone. Another example is 3D facial recognition system developed by Intel for their RealSense technology. This system uses a combination of depth sensing cameras and facial recognition algorithms to authenticate users. In healthcare industry, 3D passwords are being used to secure patient data.

For example, 3D gesture-based authentication system developed by NYU Langone Health requires doctors and nurses to input a series of hand gestures to access patient records.

Another example of 3D password usage is in banking industry. 3D password system is being used in ATMs to secure transactions. This system requires users to input a combination of their PIN, biometric authentication (such as fingerprint or iris scan), and a gesture in a 3D space. This provides a highly secure and convenient way for users to access their money and carry out transactions.

In education sector, 3D passwords are being used to secure online learning platforms. 3D gesture-based authentication system developed by University of South Carolina requires students to input a series of hand gestures in 3D space to access course materials and other sensitive information. This system has been found to be highly effective in preventing unauthorized access to student data.

Another example is in gaming industry, where 3D passwords are being used to secure user accounts. 3D gesture-based password system developed by Sony for their PlayStation 4 requires users to input a combination of hand gestures in 3D space, as well as a traditional password, to access their account. This system provides an additional layer of security to prevent unauthorized access to user data and purchases.

Future of 3D Passwords

The future of 3D passwords looks promising as it addresses the limitations of traditional password-based authentication systems and provides more secure and user-friendly authentication options. As technology advances, it is expected that 3D passwords will become more widely adopted and integrated into various applications.

One area where 3D passwords have great potential is in the field of mobile devices. With the increasing use of mobile devices for various tasks, the need for secure authentication methods is essential. 3D passwords can provide a more secure and user-friendly authentication option for mobile devices.

Another area where 3D passwords can be applied is in the healthcare industry. The healthcare industry deals with sensitive patient data, and the use of 3D passwords can provide a more secure way of accessing patient data.

In addition, 3D passwords can be integrated with other authentication methods like biometric and multi-factor authentication to provide an even more secure authentication option.

In conclusion, 3D passwords offer an advanced authentication system that adds an extra layer of security to traditional password-based systems. While they come with some disadvantages, such as a learning curve and potential usability issues, enhanced security they provide makes them a valuable addition to any organization's security measures. With increasing prevalence of cybercrime and need for stronger authentication systems, 3D passwords offer a promising solution.
