摘要： In order to acquire a suitable fingerprint image by correcting an elongated fingerprint image, a line sensor acquires fingerprint image as a plurality of line-shaped images. A computation unit computes a similarity value by use of an evaluation function for evaluating the degree of similarity between the line-shaped images. The similarity value represents the degree of similarity between a first line-shaped image and a second line-shaped image which serve as a similarity evaluation target and are included in the plurality of the line-shaped image. A compression unit compresses the first line-shaped image and the second line-shaped image when the similarity value is equal to or larger than a predetermined threshold value to generate a new line-shaped image. A generation unit generates the entire fingerprint image by combining the new line-shaped image with the other line-shaped images.

摘要： A data holding unit holds data sets each composed of a fingerprint image and recording setting data associated with the fingerprint image. A fingerprint image acquisition unit acquires a fingerprint image newly from a user. A similarity value calculation unit compares the fingerprint image newly acquired from the user and the fingerprint image held in the data holding unit, and indicates a degree of similarity therebetween as a similarity value by using a similarity evaluation function for indicating a degree of similarity between a plurality of types of fingerprint images. A load data selection unit reads recording setting data corresponding to a fingerprint image having a similarity value reaching or exceeding a predetermined value if the fingerprint image is held in the data holding unit, and reads certain data prepared in advance if not.

摘要： A first image pickup unit mainly captures the image of whole face. A second image pickup unit mainly captures an image of iris in an eye. A display unit simultaneously displays both an image picked up by the first image pickup unit and an image picked up by the second image pickup unit on divided display regions, and naturally prompts a user to operate in such manner as to include himself/herself within an image pickup range. When the user moves his/her face or an authentication apparatus upon seeing this display, a relative position or direction of the iris and the image pickup device can be set to a desired state.

摘要： In a verification apparatus, an image pickup unit picks up an image of an object to be verified. A calculation unit calculates, from the captured object image, a characteristic quantity that characterizes a direction of lines within the object image along a first direction or a characteristic quantity that characterizes the object image as a single physical quantity. Then a region from which data are to be acquired is set by referring to a characteristic quantity of the object image and, from this region, a characteristic quantity that characterizes a direction of lines within the object image along a second direction different from the second direction or a characteristic quantity that characterizes the object image as a single physical quantity is calculated. A verification unit at least verifies the characteristic quantity of the object image against that of a reference image along the second direction.

摘要： In an authentication input apparatus, an input unit is a surface for inputting data of an input device such as a pressure sensitive sensor. The input device may also be an optical sensor such as a CCD. The input unit receives from a user input of a fingerprint, a signature or the like. In inputting the signature, the input unit functions as a tablet for inputting signatures utilizing a stylus equipment or the like. In inputting the fingerprint or the signature the user specifies the type of authentication information to be inputted by pressing a fingerprint selection button or a signature selection button. Fingerprint data are obtained by the input device when the user puts the finger on the input unit after pressing the fingerprint selection button. Signature data are obtained by the input device when the user signs on the input unit 10 after pressing the signature selection button.

摘要： An input unit accepts a fingerprint image of a user. A pre-extraction and categorization unit generates pre-extracted data from the fingerprint image and uses the data to categorize the input fingerprint image into one of multiple groups. A feature extraction unit extracts fingerprint feature data from the fingerprint image by processing methods defined for the respective groups. A feature data matching processing unit matches the fingerprint feature data against fingerprint authentication data registered in a fingerprint authentication database by processing methods defined for the respective groups. An integrated authentication unit authenticates a user with the input fingerprint image based upon a result of matching.

摘要： An input unit inputs respectively a plurality of partial images corresponding to a user to be authenticated. An extraction unit extracts feature points of a fingerprint respectively from the plurality of partial images inputted. A generation unit synthesizes the feature points extracted respectively from the plurality of partial images and then generates feature point information for authentication. An acquisition unit acquires reference feature point information. A rotation unit performs phase rotation on the generated authentication feature point information so that a directional component, namely, a phase component, contained in the generated authentication feature point information approaches that contained in the acquired reference feature point information. An authentication unit authenticates the authentication feature point information whose phase has been rotated, based on the reference feature point information.

A classification unit classifies the fingerprint image inputted by the input unit into any of a plurality of groups defined on the basis of individual differences of the fingerprint. Based on the classification result of fingerprint width, namely, the type of a group determined by the classification unit, a switching control unit selects either a normal fingerprint width feature extraction processing unit or a narrow fingerprint width feature extraction processing unit provided in a feature extraction unit. A feature extraction unit processes the fingerprint image, using processing methods defined respectively for the plurality of groups. A verification data preparation unit prepares fingerprint verification data. A fingerprint identification unit checks the fingerprint verification data prepared by an identification data preparation unit against fingerprint identification data enrolled in a biological information storage unit.
