Even the strong gun laws passed by the District of Columbia in the wake of Heller, which include a registration system, fingerprinting and training requirements, an assault weapon ban, a limit on gun purchases, and other provisions far stronger than federal law, recently were upheld as entirely consistent with Heller.
If you had to use a biometric security system (fingerprint recognition, retinal scanners etc).
Most Aadhaar cards are secured by a biometric ID system - fingerprint, retina scan.
The MACCS (Molecular ACCess System) fingerprint is among the best-known substructure keys-based fingerprints [47].
Its researches have been applied in face identification system, fingerprint identification system, fire detection and identification system, machine vision, and medical imaging, and so on.
Visual sensors track objects by a 2D localization, and identification sensors (i.e., RFID system, fingerprint, or iris recognition system) are incorporated into the system for object identification.
Also, several identification sensors, such as RFID (Radio Frequency Identification) system, fingerprint, or iris recognition system, have been utilized for object identification.
For improving the performance of the system, fingerprint and speech similarity scores are pre-processed with cohort and tanh normalization methods, respectively.
These prediction approaches are usually clustered into three categories: expert systems, fingerprint-based data mining approaches and combined approaches.
Among various commercially available biometric-based systems, fingerprint-based techniques are the most mature, extensively studied, and widely deployed.
In early chemoinformatics systems, fingerprint vectors were relatively short, containing typically a few dozen components selected from a small set of features, hand-picked by chemists.
