How do attackers get around fingerprint authentication systems with an 80% success rate?

Attackers can bypass fingerprint authentication with ~80% success rate

Fingerprint authentication systems are now widely used to protect sensitive data and provide security in the digital realm. However, researchers from New York University have reported that attackers are able to bypass such systems with an 80% probability of success.

One of the reasons why fingerprint authentication systems can be fooled is that a fingerprint can be lifted from a surface, and even without much effort. An attacker can use a variety of methods such as forging a finger from skin, fingerprinting a glass or metal surface to authenticate.

Another reason is that fingerprint authentication systems can be susceptible to a replay attack. An attacker can use a fingerprint model created from a photo or fingerprint from different devices to authenticate. This method can be particularly effective because authentication systems are not always able to determine whether a submitted fingerprint is live or artificial.

Fingerprints: a vulnerability of authentication systems

Recent research has shown that fingerprint-based authentication systems have vulnerabilities that allow attackers to bypass them with an 80% probability of success. This is a major concern as fingerprints are increasingly being used for authentication on devices and in security systems.

The problem is that fingerprint authentication systems rely on recognizing the unique physiological characteristics of the finger. However, researchers have been able to demonstrate that these systems can be fooled by fake fingerprints.

Creating fake fingerprints is a labor-intensive process that requires access to the victim’s original fingerprint. However, there are situations where this is possible - for example, if the attacker gains access to fingerprint traces on surfaces that the victim frequently touches (such as in public places or on devices they use).

The researchers used a technique to create fake prints based on modeling images of prints using special materials such as plastic or silicone. They then used these fake prints for authentication and were able to successfully hack into systems 80% of the time.

This vulnerability emphasizes the need for continuous improvement of fingerprint-based authentication systems. Possible defenses include improving recognition algorithms, using additional biometrics (e.g., hand vein scanning), and regularly updating hardware to detect and prevent spoofed fingerprints.

It is important to note that fingerprint authentication is still more secure than using passwords, as spoofed prints require physical access to the original print. However, this vulnerability must be taken into account when designing and using fingerprint-based authentication systems.

New circumvention methods

Attackers use various techniques to bypass fingerprint authentication systems with a high probability of success. Some of these techniques include:

Fingerprint forgery: An attacker can use various materials such as clay, silicone, or plastic to create a fake fingerprint. This can be done by using prints that have been copied from a surface that the user has left their fingerprint on.
Photography of a fingerprint: An attacker can use a photograph of a fingerprint taken at a high resolution, such as with a high quality camera. This photograph can then be printed on transparent film or other material to create a fake fingerprint.
Fingerprint from a trace: An attacker may use a trace of a fresh fingerprint that has been left on a surface, such as glass or metal. Such a trace can be copied using fingerprint devices or photographed and then a fake fingerprint can be created.

These new methods of circumventing fingerprint authentication systems are quite effective and allow attackers to gain access to protected information with a high probability of success. This raises questions about the reliability and security of such systems, and the need to develop new authentication technologies that are more resistant to these types of fraud.

Probability of successful hacking

Attackers are able to bypass fingerprint authentication systems with a fairly high probability of success - up to 80%. This is due to imperfections in the technology used to read and store fingerprints, as well as the possibility of forging fake fingerprints.

One of the reasons for this high hacking success rate is that some fingerprint reading systems use simplified recognition algorithms, making them more vulnerable to attack. In addition, some devices may have insufficiently accurate sensors or poorly configured settings, increasing the likelihood of fingerprint reading errors.

Another major factor affecting the likelihood of a successful hack is the possibility of creating and using fake fingerprints. Some researchers have developed methods to create such fake fingerprints that can be successfully used to bypass authentication systems. This can be accomplished by creating fingerprint models using fingerprints obtained from various sources such as photographs or traces left by everyday life.

Therefore, developers of fingerprint authentication systems should continuously improve their technologies and algorithms to reduce the risk of possible tampering. Additional levels of authentication should also be utilized to increase system security, such as requiring the use of passwords in conjunction with a fingerprint or the use of two-factor authentication.

Recommendations and precautions

The following precautions are recommended to improve security and protect against attacks related to bypassing fingerprint authentication systems:

Use additional authentication methods: in addition to fingerprint, incorporate the use of passwords, PINs, or other available options to confirm identity.
Install and activate two-factor authentication: enabling this feature will add another layer of security by requiring you to enter a special code received on your phone or via email.
Periodically update software and firmware: attackers can exploit known vulnerabilities in authentication systems, so it’s important to have the latest software versions and update them as soon as available.
Be careful when unlocking your device in public places: avoid unlocking your device, especially using your fingerprint, in crowded places or in the presence of strangers.
Do not share your fingerprint with outsiders: be careful not to leave your fingerprint on surfaces that could fall into the hands of intruders for the purpose of using it.
Keep up to date with current security news: being aware of possible vulnerabilities and attack methods will help you maintain a high level of security and respond to threats in a timely manner.

Given the ability to bypass fingerprint authentication systems with a high probability of success, following these tips and precautions will help strengthen the security of your personal information and devices.
