Live Scan technology is revolutionizing background checks with its fast, accurate, and secure digital fingerprinting solutions. Explore the efficiency and wide-ranging applications of Live Scan in our latest blog, and see why it’s becoming the preferred method for modern identity verification and security screening.
What is a live scan?
A Live Scan is a digital method of capturing fingerprints in a computerized format. Instead of using ink and paper, an individual’s fingerprints are scanned directly into a system using a specialized scanner. This process captures an electronic image of the fingerprint, which can then be submitted electronically to law enforcement or other agencies for the purpose of background checks, identity verification, and more.
Live Scan technology significantly improves the efficiency and accuracy of fingerprinting. It reduces the likelihood of errors commonly associated with traditional fingerprinting methods, such as smudges or incomplete prints. Additionally, because the fingerprints are digitized, they can be quickly transmitted to relevant agencies for processing, speeding up background checks and other identity verification processes.
Live Scan is commonly used for various purposes, including employment screening, professional licensing, certification, volunteer work, and compliance with legal requirements. It’s particularly prevalent in sectors where security and accurate identification are paramount, such as education, healthcare, law enforcement, and financial services. The technology provides a secure, fast, and reliable means of performing background checks, making it an essential tool in modern identity verification practices.
How accurate is live scan?
Live Scan fingerprinting is generally considered to be very accurate due to its digital technology and methodology. The accuracy of Live Scan systems hinges on a few key aspects:
1. Quality of Fingerprint Capture:
Live Scan devices capture high-quality images of fingerprints, significantly reducing the issues associated with traditional ink-based methods, such as smudging or uneven pressure, which can lead to inaccurate or unclear prints. However, the accuracy can still be affected by various factors such as the cleanliness of the scanner surface, the condition of an individual’s skin (e.g., scars, cuts, or calluses), and the technique used by the operator.
2. Advanced Matching Algorithms:
Once captured, fingerprints are processed using sophisticated algorithms that compare the unique features of the prints (like loops, whorls, and arches) against databases. These algorithms are constantly being refined and improved, contributing to high levels of accuracy in matching and identifying individuals.
3. Comprehensive Databases:
The fingerprints are checked against extensive and comprehensive databases maintained by agencies such as the FBI, state-level law enforcement agencies, and other organizations. The breadth and depth of these databases enhance the likelihood of accurately matching fingerprints to their rightful owners or identifying individuals with criminal records.
4. Error Rates:
While Live Scan is highly accurate, no system is infallible. The FBI has reported that the accuracy of fingerprint matching depends on the quality of the print capture and the conditions under which the prints were taken. The error rate for fingerprint matching is very low, but false positives (incorrectly identifying someone as a match) and false negatives (failing to identify a true match) can still occur, albeit rarely.
5. Manual Review:
In cases where the automated system cannot make a definitive match, fingerprints may be manually reviewed by experts. This additional step helps to mitigate errors and improve the overall accuracy of the system.
