Information processing program and information processing device

Provided are an information processing program and information processing device capable of creating verification information not susceptible to be affected by the conditions under which biological information is acquired even when the size of the image containing the biological information is smaller than before. An image is acquired (S1), and a base point is determined from the image (S2). Sample information indicating changes in color information around the base point is acquired (S3). The sample information is information in which multiple samples are associated with center information corresponding to the position of a first reference point in the image. The sample is information in which color information of a second reference point is associated with position information of the second reference point. Frequency information generated on the basis of the sample information acquired in (S3) is acquired (S4). The frequency information is information in which frequency components ofchanges in the color info
