ID Verification, Validation, and Authentication – What’s the Difference?

ID Verification, Validation, and Authentication – What’s the Difference?

Not all identity verification is created equally. Many businesses think they are performing age verification, when the hardware and software they are using is not actually equipped to detect suspicious IDs. More than 46% of college students say they’ve used a fake ID to get past age restrictions. And today’s fake IDs can be imperceptible to the naked eye. So, what level of ID verification are you performing at your business?

What is ID Scanning?

ID scanning simply means an ID was digitally scanned. As there are hundreds of scanners on the market today, there is wide variance in scanning accuracy and fake ID detection.

ID scanning does not necessarily include any level of verification or authentication. In many cases, the scanning software is simply calculating if the birth and expiration dates indicate that a given individual is of age, and that their ID is not expired. There are no requirements for embedded security features.

ID Scanning Considerations

  • Hardware capabilities. Low quality hardware will be less capable of detecting fake IDs.
  • Sophistication of 2D barcode parsing algorithm.
  • Breadth of IDs you need to verify on a daily basis. Large states with lots of ID holders have often been seen by algorithms more frequently, and thusly fakes are detected more readily.
  • Third party integrations. If you have a POS system or database, you will want scanning software that integrates, especially if you have PII retention requirements.
  • Staff training
  • State-level compliance requirements.

What is 2D Barcode Security?

At IDScan.net our AI performs more than 75 algorithmic security checks on the 2D barcode (PDF417) during digital scanning.

These are essentially what could be called “easter egg checks.” Most ID formats have some intentional quirks
or known consistencies. This might be something as simple as “for all Nebraska IDs, the ID number always starts with an A or a Q.” These are validation points that our algorithms have identified over our 15+ years scanning IDs, and so we’ve built them into our 2D barcode security checks to help catch some fake IDs.

2D barcode security checks can be done using all ID scanners, including mobile phones.

Data from the ID can also be parsed into your database, CRM, or POS at this stage.

Low quality fake IDs are often unable to pass barcode security. So this is a great base for age verification and fake detection. When tested against a library of known fakes, more than half failed this stage of verification.

For an additional layer of ID verification, some scanners can compare the data contained in the barcode with the data on the front of the ID, using optical character recognition.

What is ID Authentication?

Authentication is the most stringent stage of ID verification, which requires specialty hardware. A phone, or low end scanner, will not be equipped with the type of camera or lighting required to truly put an ID through its paces.

At this stage, every aspect of the ID will be examined using powerful cameras. The ID will be checked against hologram and watermark libraries. It will be scanned using white, infrared and UV light. It will also undergo an additional series of algorithmic checks which look for variances in spelling, spacing, and

ID design versus known standards. Six images of the ID are simultaneously compared.

Because of the rigor of authentication, reading and returning results for each ID can take up to 10 seconds. This time is variable depending on the scanner, as well as the processing power of the computer that is being used to run the authentication software.

ID authentication can be performed concurrently with 2D barcode security checks and ID parsing. Authentication provides the highest degree of fake detection and accurately catches up to 95% of suspicious IDs. Even the best fake ID manufacturers have difficulty passing the hundreds of checks that are done in the authentication stage.

Best-in-Class ID Authentication

  • Minimum 400 DPI image capture for both sides of the ID
  • Simultaneous six image comparison
  • UV hologram screening library
  • IR watermark screening library
  • White light scanning
  • Infrared light scanning
  • Additional algorithmic checks on the physical ID
  • Results returned in 15 seconds or less

ID authentication requires specialty scanners. These scanners include embedded cameras, various types of lights, and often motors which can pull the ID in and out of the device. They require connection to a computer which can perform the data processing required to determine the ID’s legitimacy.

What is Identity Verification?

Beyond checking the physical ID, there is an additional layer of verification that can be performed – matching the human holding the ID to the ID itself. This can be performed in a number of ways but commonly involves facial recognition software.

In-person, this can be performed using a web camera, which matches the live photo of the individual’s face to the photo on their ID card.

If the ID checking is remote, or mobile, this can be performed using a selfie with the user’s existing mobile device.

In either case, anti-spoofing should be layered on top of the facial recognition, to ensure that a photo or video is not being used to trick the software.

Results can be returned in less than 3 seconds in most cases.
