Security professionals know that the best approach for the highest level of identity confirmation is to use multi-factor authentication consisting of something someone has – like an access card, something someone knows – like a pin code, and something someone is – like a fingerprint. The combination of these methods provides a level of assurance ideally suited for situations involving national security, nuclear weapons and other important matters.
But this approach is overkill for most access control systems. The vast majority of access control systems are used for everyday purposes in business offices, factories, campuses and housing, and similar places. These facilities all require reliable, high-accuracy identity confirmation while controlling costs and processing users quickly and efficiently.
So the question is, what is the best credential to use for fast and accurate access control identity authentication? The answer: facial recognition.
Facial recognition as a credential is the ideal solution for organizations looking to deploy the latest, most accurate and fastest technology while simultaneously improving the user experience in most access control applications. .
From unlocking cell phones to identifying fugitive criminals, facial recognition technology continues to be the technology of choice in a variety of use cases that require the highest level of personal identification and authentication. It is therefore not surprising that facial recognition is widely adopted as the superior form of access control credential. Faces as access control credentials provide many benefits that ID badges, passwords, proximity cards, mobile devices, and other biometrics simply cannot.
Here are 5 reasons why facial recognition is the right choice for access control identity verification:
1. Facial recognition can integrate with all access control systems
Every access control system (ACS) requires a mechanism to evaluate access requests and determine if the requestor is authorized to access the controlled resource. In the past, keypads and access card readers were the most common way for a user to request access. Since facial recognition systems can provide the same type of authorization signals to an access control system as these older methods, they can integrate with every ACS.
Facial recognition systems transform any person’s face into an identifier. Faces can be used either as a standalone access solution, or they can be combined with other credentials for added security as a source of multi-factor authentication.
2. Faces are frictionless and contactless
When a person’s face is their ID, you don’t have to touch anything to access it. No keyboards to type in PINs, no fingerprint readers to touch, and no phones or pocket IDs to scan. Users simply glance at a reader and, with the appropriate permissions, the door is unlocked. This reduction in touch surfaces reduces the potential spread of germs and harmful bacteria, thereby promoting a safe and healthy workplace.
As mentioned above, facial recognition integrates seamlessly with existing access control systems, so organizations can replace their access control touchpoints without having to tear down and replace an entire system. . Implementing a contactless access process also allows employees and visitors to a facility to move around, since people no longer stop to find their physical credentials or enter their PIN codes. In this way, facial recognition provides a frictionless access experience that limits close contact and promotes social distancing, while improving operational efficiency by reducing wait times at entry points.
3. Face recognition is accurate and fast
Today’s most advanced facial recognition technologies use powerful computing technologies to deliver precise recognition accuracy faster than ever. Maintaining a high percentage of correct recognitions across a range of viewing conditions is essential for access control applications, so only facial recognition systems that use the latest AI and processing technologies provide the most reliable and accurate solutions.
Fast processing also supports a fast registration process, whether when registering new users or using an existing database, and provides a better user experience.
For example, Intel’s ANN algorithms, which today are leveraged by some facial recognition platforms, also enable extremely fast processing.
4. Faces cannot be lost, forgotten or stolen
Unlike physical access control credentials, a user cannot forget their face at home, drop their face in the parking lot, or lend their face to someone else. A user’s face is always with them and with nothing to take away, there is nothing to lose, forget or steal. Replacing lost or solemn credentials such as badges or key fobs is expensive, not to mention the administrative hassle. Organizations that rely solely on facial recognition as an access control credential eliminate the manual tasks associated with printing, issuing, and re-issuing physical credentials.
Lost or stolen credentials also present a significant security risk. Organizations looking to enforce a zero-trust environment can struggle to do so when physical access credentials are easily lost, stolen, and shared, often without the knowledge of the owner. The loss of physical credentials due to theft or negligence places an undue burden on security administrators who must interrupt their workday to restrict access to the lost credential and then issue a new one. identification. These issues are entirely eliminated when facial recognition is the sole source of truth for an access control system.
5. Facial recognition is highly secure
Some low-quality facial recognition systems, and those that use outdated technology, can be tricked by hackers or bad actors who hold an authorized user’s image or video in front of the camera in an attempt to gain access. However, most facial recognition vendors today incorporate anti-spoofing features designed to detect and thwart such attempts.
Additionally, facial recognition as an access control identifier only works if a user consents to be enrolled in the system, i.e. if users “opt in” to the service and are never used for general surveillance. Such consent should eliminate potential privacy issues, but some companies take extra steps to ensure the privacy of personal data. The most advanced systems do not capture or store any actual image of an individual’s face, further ensuring privacy. Some systems also use encryption as an additional layer of security to protect against unauthorized system and database access. All personal user data is still encrypted in transit and at rest.
Compared to other traditional credentials such as physical access cards, PIN codes and mobile credentials, facial recognition clearly stands out when it comes to facilitating a zero trust environment. . Modern facial recognition systems provide highly accurate, secure, and frictionless facial recognition capabilities to access new and existing screening systems while maintaining individual privacy. Organizations looking to deploy facial recognition as a credential can expect increased operational efficiency, reduced administrative tasks, and a streamlined access process that will ensure security while improving user experience.
