An object detection device (10) extracts feature for input data utilizing an encoder, the input data including labeled data and unlabeled data and detects object in each of the input data, utilizing an object detector. The object detection device (10) generates region data for each of the input data, each of the region data corresponding to the detected object and generates restoration data from the region data and meta-information related to the detected object for each of the input data utilizing a decoder corresponding to the encoder. The object detection device (10) executes learning of the encoder and the object detector based on a result detected by the object detector and a label associated with the input data, when the input data is labeled data, and executes learning of the encoder, the object detector, and the decoder, based on the input data and the restoration data.
摘要:
Disclosed is an authentication apparatus easily achieving convenience and high accuracy in authentication. The authentication apparatus has an authentication accuracy simulation section that simulates authentication accuracy and also has a registration information setting section that sets an ID and biometric information input as registration information. The authentication accuracy simulation section uses an ID and biometric information that has been input as registration information by a user at the time of registration and the registered registration information to simulate authentication accuracy with which the user is authenticated. When the authentication accuracy simulated by the authentication accuracy simulation section does not satisfy a predetermined condition, the registration information setting section rejects registration of the ID input as the registration information.

In personal authentication using biological information, biological information is protected without degrading the authentication accuracy. An obtaining unit 311 of a biological information obtaining apparatus 301 obtains biological information for authentication, and an extracting unit 312 extracts first feature information from biological information for authentication. A generating unit 321 of a biological information collating apparatus 302 generates encrypted position correction information, and encrypted position correction information is transmitted to the biological information obtaining apparatus 301. A correcting unit 313 decrypts encrypted position correction information to obtain position correction information, and by correcting first feature information, performs alignment between first feature information and second feature information extracted from biological information for registration. A transforming unit 314 transforms corrected first feature information, and transmits transformed first feature information to the biological information collating apparatus 302. A collating unit 324 collates transformed first feature information and transformed second feature information stored in a storing unit 325, and transmits a collation result to biological information obtaining apparatus 301.

摘要:
An authentication processing device (10) receives biometric data to be checked from a biometric measuring device (20); transform the biometric data that is input from the biometric measuring device (20) by using a checking transformation parameter that is different from a registration transformation parameter; and creates checking biometric data. Then, the authentication processing device (10) performs a differential transformation process on the created checking biometric data by using a differential parameter by which a transformation state transformed by the checking transformation parameter and a transformation state transformed by the registration transformation parameter have the same state. Thereafter, the authentication processing device (10) checks the transformed checking biometric data against the registration biometric data stored in a transformation registration data DB (50) and performs authentication.
摘要:
A data collation apparatus has: a collation unit which calculates a similarity between input data measured by a measurement apparatus and each of registered data; and a calculation unit which adjusts, if a similarity of first registered data of which similarity with the input data is highest is lower than a first threshold, and a difference between the similarities of the first registered data and second registered data of which similarity with the input data is second highest is smaller than a predetermined value, or if a degree of separation to indicate a distance between the similarity of the first registered data and a similarity distribution of a group of registered data items of which similarities with the input data are second highest or lower is smaller than a predetermined value, the parameters of the measurement apparatus, and instructs the measurement apparatus to remeasure the measurement subject.
