INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND STORAGE MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18265289 titled 'INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND STORAGE MEDIUM
Simplified Explanation
An information processing device is described in this patent application. The device includes an acquisition unit that acquires both a rolled print and a slap print from the same finger. It also includes an extraction unit that extracts first feature points from the rolled print and second feature points from the slap print. Finally, an estimation unit estimates the amount of correction work performed by a user on a non-common region of the rolled print based on the ratio of first feature points that have no correspondence with the second feature points.
- The device acquires both a rolled print and a slap print from the same finger.
- First feature points are extracted from the rolled print, and second feature points are extracted from the slap print.
- The estimation unit calculates the ratio of first feature points that have no correspondence with the second feature points.
- Based on this ratio, the estimation unit estimates the amount of correction work performed by the user on a non-common region of the rolled print.
Potential applications of this technology:
- Biometric authentication systems
- Forensic analysis
- Identity verification in various industries (e.g., banking, healthcare)
Problems solved by this technology:
- Improves accuracy in comparing rolled prints and slap prints
- Provides a method to estimate the amount of correction work performed by a user on a non-common region of a rolled print
Benefits of this technology:
- Enhanced security in biometric authentication systems
- Improved efficiency in forensic analysis
- More reliable identity verification processes
Original Abstract Submitted
An information processing device includes: an acquisition unit that acquires a rolled print and a slap print on the same finger; an extraction unit that extracts first feature points from the rolled print and second feature points from the slap print, respectively; and an estimation unit that, based on a ratio occupied by the first feature points having no correspondence with the second feature points out of the first feature points included in a common region that is common to the rolled print and the slap print, estimates a first work amount of correction work performed by a user on a non-common region excluding the common region from the rolled print.
