In the world of digitalization, biometric security such as face IDs, retina scans and fingerprints are introduced to enhance the security of our devices. Just imagine the revolution it has brought to make our life more convenient, from accessing your smartphone with your fingerprint to logging into your bank account using your face ID. It offers a highly secure and reliable level of personal identification which is generally harder to forge or steal as compared to the traditional methods.

However, like other technologies, biometrics are also prone to significant hacking attempts. Biometrics being the most reliable source, these days, becomes the most vulnerable to potential risks. Thus, appropriate measures such as implementing strong encryption protocols, regularly updating biometric systems, and ensuring strict access control can be used to increase the overall security and protect sensitive data.

What is Biometric Hacking?

Biometric hacking refers to the unauthorized access to a person’s biometric data and misuse. Malicious attackers can intercept this data during transmission or obtain it from a storage location such as a computer database. When the hacker obtains the biometric data, they can use it to impersonate the victim and gain access to their accounts or sensitive information. Each individual has a unique biometric data, which cannot be easily changed, this makes it a valuable target for hackers.

How Biometrics is Hacked?

There are various ways that can be used by the hackers to hack biometrics. Some of the methods are discussed below:

1. Skimming- This method involves using various devices that are specifically designed for collecting fingerprint data. For instance, a skilled hacker may employ a skimmer device that can be secretly placed on a fingerprint scanner which allows them to covertly capture and extract significant data. 
2. Spoofing- With the advanced skills, hackers employ sophisticated techniques to create counterfeit biometric inputs including forged fingerprints or fabricated iris images. These measures are designed to trick the system into unintentionally granting unauthorized access, indicating a serious threat to security and privacy.
3. Replay attacks- Many times, hackers employ modern tools to record biometric data during a legitimate access attempt. They cunningly capture and store the data and exploit it later by replaying it to gain unauthorized access, breaching security measures, and jeopardizing confidential information.

Real-life Case Studies of Hacked Biometrics

In 2015, the U.S. Office of Personnel Management (OPM) was the victim of a massive data breach where the personal information of more than 21 million people was compromised. The hackers were able to gain access to fingerprint data of 5.6 million individuals, which is one of the largest known breaches of biometric data. This incident raised serious concerns about the biometric security that can be used for identity theft or other malicious intentions. 

In 2016, a team of researchers from Michigan State University explained that it is possible to create fake fingerprints, which can fool fingerprint scanners. The researchers created fake fingerprints using gelatin and inkjet printers. These fake fingerprints are used to unlock smartphones and laptops equipped with fingerprint scanners.

In 2017, a security researcher discovered a vulnerability in how the fingerprint data is handled in Android devices. The researcher found it impossible to obtain fingerprint data from an Android device and create a 3D-printed replica of a person’s fingerprint. It was also found that the Android fingerprint data was not encrypted and made it easier to steal.

These cases show how biometric data can be compromised. As we are storing more and more data in digital form, hence it is more important to consider the security risks associated with these types of data.

How Biometric Hacking Impacts Businesses?

Biometric hacking can create severe consequences, as they are unique and cannot be changed easily once compromised, unlike other passwords. Once the hacker obtains your biometric data, they can use it to impersonate you, leading to identity theft and other serious issues. Biometric hacking can create the following impacts on businesses:

1. Data breach- Unauthorized access to biometric data can lead to significant data breaches by exposing sensitive information of a company or client.
2. Financial loss- The malicious attackers often use the stolen biometric data to perform financial fraud, which can result in massive financial loss to the victim. The consequences created by the data breach can lead to substantial financial loss due to the cost of managing the breach, legal liabilities and potential fines for non-compliance with data protection regulations.
3. Loss of intellectual property- Hackers can gain access to protected areas of proprietary information or intellectual property, which can be stolen and used for malicious intentions.
4. Reputation damage- Loss of biometric data can create serious impact on the reputation of a business, through losing customer’s trust and facing public backlash.
5. Operational disruption- Unauthorized access via biometric hacking can lead to potential operational disruptions, creating an impact on productivity and efficiency.
6. Legal consequences- Businesses can face legal consequences that fail to safeguard their biometric data. This can result in lawsuits, regulatory fines and other legal issues.

How Can You Mitigate the Risk of Biometric Hacking?

There are many ways by which you can mitigate the risk of biometric hacking. Below, we have discussed some biometric security measures that can help:

1. Multi-Factor Authentication (MFA)- You can use more than one method of authentication. Such a system requires a fingerprint scan and a password, making it harder for hackers to gain unauthorized access.
2. Video surveillance- Video surveillance systems are important to detect and deter biometric hacking attempts. Advanced features like motion detection, facial recognition, and anomaly detection, can monitor potential access points in real-time. Any type of suspicious activity around biometric data access points can initiate immediate alerts, resulting in quick response. The recorded footage, thus obtained, can be valuable evidence during investigations. This helps to identify the perpetrators and understand the modus operandi of the breach.
3. Advanced access control methods- Another robust deterrent against biometric hacking is the advanced methods of access control. Methods such as Role-based Access Control (RBAC) and Attribute-Based Access Control (ABAC) can be employed to restrict access to biometric data based on the user’s role or specific attributes. This way, only the authorized individuals can access sensitive biometric information and reduce the potential attack surface for hackers. Moreover, privileges can be adjusted on the basis of several factors such as location, time and perceived threat levels, which provides adaptive security. Alternative approaches like least privilege access ensure that each user has the minimum levels of access necessary to perform their tasks to mitigate the risk of biometric data theft.
4. Physical intrusion detection systems- These intrusion systems are another crucial tool to strengthen the defenses against biometric hacking. These systems are used to monitor and report unauthorized trials to access physically secured areas like server rooms where biometric data may be stored. These detection systems utilize a combination of sensors, alarms, and notification systems to alert security personnel instantly of any unauthorized access. In turn, this helps for swift response to potential threats, which reduces the window of opportunity for hackers to breach the biometric data security. 
5. Anti-spoofing measures- Advanced biometric measures are used to detect and prevent spoofing attempts. Some fingerprint scanners use live detection technology to ensure the presented finger is not fake.
6. Secured data transmission and storage- Biometric data should be securely transmitted and stored to eliminate interception by malicious attackers. This involves encryption or storing data in a format which is of no use to hackers without the proper decryption key.
7. Regular update of software- Keep your biometric system’s software updated that ensures you have the latest security measures at your place. 
8. Training of employees- Human element can be the weakest link in any security system. Hence, training employees on the risks of biometric hacking and ways to prevent tampering with the security systems.

Shall We Rely On Biometric Security?

As the world is moving towards a digital landscape, our private data is becoming more vulnerable to theft and hacking. In instance, biometric data is a serious commodity for identity thefts and is used to gain access to sensitive information and accounts. 

Though biometrics provide a secure way to protect our data, they are not always foolproof. The threat actors have found several ways to bypass biometric security systems. They may continue to find more new ways to exploit, because of advancements in technology. 

The ultimate thing we could do to protect ourselves is to be aware about the latest security threats and to use biometric security systems in line with PIN or password. Besides, your employees can be your greatest assets or can become your greatest liability too. So, training your employees becomes an essential element in cyber security.
