Identification device, computer readable medium storing identification program and identification method

A method of producing a tablet in which an uncoated tablet is coated by a coating agent, the method including: a coating process of coating uncoated tablets with a coating agent by spray coating the coating agent onto tablets that are churned and tumbled inside a container, and drying the tablets inside the container by supplying drying air into the container and exhausting air from the container, wherein spray coating conditions, including air supply temperature, air supply rate, and spray speed, are controlled according to the weight of the coating agent with which the uncoated tablets are coated, such that the humidity of air exhausted during spray coating is within a range of from 14% RH to 30% RH.

Tablet having uniquely identifiable shape, tablet verification device and program

A data acquiring apparatus includes: an acquirer that acquires feature data, as registration data, from an image including an object to be registered, the feature data representing a feature that is distributed in a region of a predetermined size determined based on a position defined by an external shape of the object and a position of printing information that has been printed on the object; and a memory that stores the registration data acquired by the acquirer as data for determining identity of the object.

Data acquiring apparatus, printing apparatus, and genuineness discriminating apparatus

A first image pickup unit picks up a first image including a conveyed object. A printing unit performs printing on the object based on the first image. A second image pickup unit picks up a second image including the object on which printing has been performed. A check unit checks a print state of the object in the second image. A first acquisition unit acquires feature data from one of the first image and the second image, as registration data. A second acquisition unit acquires feature data from the other image of the first image and the second image, as collation data. A verification unit compares the registration data and the collation data and verifies that reliability of the registration data is equal to or greater than a predetermined criterion value. A storage stores the registration data as data for determining an identity of the object.

Printing device, method for printing, and non-transitory computer readable medium storing program causing computer to execute process for printing

An authentication information management system includes an information processing terminal that transmits check target authentication information and an authentication information management apparatus. The information processing terminal includes a transmission unit that transmits account identification information used to identify registered authentication information. The authentication information management apparatus includes a receiving unit that receives the account identification information transmitted from the information processing terminal, and an association unit that associates terminal identification information used to identify the information processing terminal with the registered authentication information identified using the received account identification information. In a case where check target authentication information has been transmitted, authentication is performed in accordance with whether the transmitted check target authentication information corresponds to the registered authentication information with which the terminal identification information used to identify the information processing terminal is associated.

Authentication information management system, authentication information management apparatus, recording medium, and authentication information management method

An authentication serverstores, for each of one or more objects to be registered, unique pattern information of a surface of the object to be registered and a personal identification number into a database in association with each other, acquires unique pattern information of a surface of an object to be authenticated which is related to an authentication request, and a personal identification number, extracts, from the database, unique pattern information stored in association with the personal identification number related to the authentication request, and determines whether the extracted unique pattern information includes unique pattern information corresponding to the unique pattern information related to the authentication request.

Authentication system and non-transitory computer readable medium

In authentication based on an image region read from a surface of a target object, authentication based on a position corresponding to the image region is executed. An authenticating serverreceives an image region as an authentication target read from a surface of a target object possessed by a user together with an authentication request from the user, identifies a position corresponding to the image region as the authentication target and one reference image region corresponding to the image region as the authentication target in a plurality of previously stored reference image regions read from respective surfaces of a plurality of target objects, and executes authentication in response to the authentication request based on the identified position.

Authenticating apparatus, authenticating system and storage medium

A comparison service provider receives, from each of plural object-related information management servers, image information items representing unique patterns included in surfaces of objects and identification information items of the objects, stores the image information items and the identification information items received, receives from a user device an image information item representing the unique pattern included in the surface of the object, identifies one of the identification information items stored based on the image information item received, and transmits to the user device the identification information item identified or a related information item of the object stored in the object-related information management server as related to the identification information item identified.
