Abstract: An authentication system according to one aspect of the present disclosure includes: at least one memory storing a set of instructions; and at least one processor configured to execute the set of instructions to: track an object included in a video captured by a first capture device; detect a candidate for biometric authentication in the object being tracked; determine whether biometric authentication has been performed for the candidate based on a record of biometric authentication performed for the object being tracked; and perform the biometric authentication for the candidate based on a video of an authentication part of the candidate when the biometric authentication has not been performed for the candidate, the video of the authentication part being captured by a second capture device having a capture range including a part of a capture range of the first capture device.

Abstract: The disclosure is inputting a first image obtained by capturing an object of authentication moving in a specific direction; inputting a second image at least for one eye obtained by capturing a right eye or a left eye of the object; determining whether the second image is of the left eye or the right eye of the object, based on information including the first image, and outputting a determination result associated with the second image as left/right information; comparing characteristic information relevant to the left/right information, the characteristic information being acquired from a memory that stores the characteristic information of a right eye and a left eye pertaining to object to be authenticated, with characteristic information associated with the left/right information, and calculating a verification score; and authenticating the object captured in the first image and the second image, based on the verification score, and outputting an authentication result.

Abstract: A first-aid information provision system of the example embodiments includes: an information display device that includes first capture means for capturing an iris image, code acquisition means for acquiring a code associated with the captured iris image, and code display means for displaying the acquired code; and an information output device that includes second capture means for imaging the code displayed by the information display device, first-aid information acquisition means for acquiring first-aid information about an individual associated with the iris image by using the imaged code, and first-aid information output means for outputting the first-aid information.

Abstract: The present disclosure is a thermal transfer sheet including a substrate and a transfer layer, the transfer layer containing a luster pigment, wherein, when an image of the sheet is taken from a side on which the transfer layer is present, the image is analyzed, dark and light portions of the analyzed image are inverted, automatic thresholding is performed in order to determine a threshold value of a brightness distribution, binary representation is subsequently performed, and the number and the total area of the black portions and the total area of the white portions are calculated, the ratio of the total area of the black portions to the total area of the white portions is 0.03 to 0.5, and the black portions have an average area of 100 to 300 ?m2.

Abstract: Provided is a powder hair dye composition capable of, in a hair-dyeing treatment intended to give a sharp black hue, suppressing the development of redness without being affected by the leave-on time required for the hair-dyeing treatment, while ensuring a sufficient hair-dyeing power. The powder hair dye composition contains (A) sodium percarbonate whose content is 1.8 to 3.7 mass % at the time of use, (B) p-phenylenediamine sulfate, and (C) m-aminophenol sulfate.

Abstract: A powder hair dye composition includes component (A) to component (C). The content of the component (A) at the time of use is 1 to 5 mass %. The component (A) is sodium percarbonate. The component (B) is sodium carboxymethyl cellulose. The component (C) is a thickener other than the component (B).

Abstract: A hair dye composition is characterized by containing (A) HC BLUE No. 2, (B) DISPERSE VIOLET 1, and (C) at least one of HC YELLOW No. 2 and HC YELLOW No. 4 and has a pH of 7-11. The mass ratio of the content of (A) HC BLUE No. 2 to the content of (B) DISPERSE VIOLET 1 is preferably 1 to 30. The hair dye composition preferably further contains (D) DISPERSE BLACK 9.
