Digital fingerprints include data indicative of interior features or structures of an object. The physical object may be rigid or malleable. The digital fingerprints may also include data indicative of features on an exterior surface of the object. Digital fingerprints may uniquely identify an object with respect to other objects, even with respect to other objects of a same type or class of objects. The technology may be relatively invariant to changes in scale, rotation, affine, homography, perspective, and illumination as between a reference digital fingerprint and a later acquired or generated digital fingerprint. Digital fingerprints may be used to authenticate an object as being a second instance or appearance of a previously digitally fingerprinted object.

Depth-based digital fingerprinting

Apparatuses and methods associated with preserving authentication under item change are disclosed herein. In embodiments, acquiring digital image data of an image of at least a portion of a target physical object; extracting features from the image data to form a digital fingerprint; querying the database system to seek a matching record based on the digital fingerprint; based on an amount of difference between the digital fingerprint and a stored digital fingerprint of the database, update the database system to output a new indication of a new match to the physical object for any new samples that are not matchable to the stored digital fingerprint within a first predetermined similarity threshold provided the new samples are matchable to the digital fingerprint within a second predetermined similarity threshold. Other embodiments may be disclosed or claimed.

Preserving authentication under item change

Facial biometric systems and methods employ digital fingerprints that represent facial characteristics. These systems and methods may perform various digital fingerprint related processes including induction (acquiring of the facial data, generation of a digital fingerprint and storing in a database) and authentication (a process of using the digital fingerprint of the face to perform biometrics). The facial biometric system and method combines these processes with a particular set of hardware to perform the facial biometrics process that is novel and provides benefits and capabilities not achievable by other biometric systems and methods.

Hand biometric systems and methods use digital fingerprints generated from images of at least a portion of hand. These systems and methods may perform various digital fingerprint related processes including induction (acquiring of the hand biometric data, generation of a digital fingerprint and storing in a database) and authentication (a process of using the digital fingerprint of the hand to perform biometrics which are known processes that may be performed using digital fingerprints, and may even be control anonymous access to controlled areas or vehicle. The hand biometric system and method combines these processes with a particular set of hardware to perform the hand biometrics process that is novel and provides benefits and capabilities not achievable by other existing biometric systems and methods.

Apparatuses and methods associated with multi-level authentication are disclosed herein. In embodiments, a method includes authenticating a physical object of a plurality of physical objects that together form an aggregate physical object; storing in a database system relationship information reflecting a relationship between the aggregate physical object and the plurality of physical objects; attempting to authenticate a target physical object; responsive to matching the target physical object to the aggregate physical object based on the attempt to authenticate the physical target: identifying in the database system a database record corresponding to the aggregate physical object; storing in the database record authentication data reflecting the match between the target physical object and the aggregate physical object; and storing an indication of a re-authentication of the physical object in the database system based on the relationship information. Other embodiments may be disclosed or claimed.

Multi-level authentication

Docking station

A turret tool measuring device which includes an annular member shaped to enable it to fit easily and securely into the hub of a screw machine tool turret. A flange member formed integrally with the annular member, which together form the base element of the invention, cooperates to ensure that the annular member remains securely in the hub and the device is fully rotatable about the turret's central axis. The flange member includes the means to receive a rod member on which a guide member may be mounted. The guide member includes an opening conformed to slidably receive the rod member and an indicator arm extending therefrom. The guide member also includes a locking element adapted to fixedly secure the guide member to the rod when the device is in the process of measuring the longitudinal position of a turret tool.
