摘要： A reading device includes a first light source, a second light source, a first reading unit, a second reading unit, a comparison unit, and a correction unit. The first source irradiates an object to be read, with first light having a first transmittance to the object. The second source irradiates the object with second light having a second transmittance to the object. The first reading unit reads the first light from the object to output first image data. The second reading unit reads the second light from the object to output second image data. The comparison unit compares a data difference between the first and second image data. In a case where the data difference is equal to or larger than a threshold, the correction unit corrects data of an image area having the data difference equal to or larger than the threshold in the first or second image data.

摘要： An authentication apparatus includes circuitry that selects at least one of a first light emitting device and a second light emitting device. The first light emitting device emits light in a certain wavelength region. The second light emitting device emits light in a wavelength region different from the certain wavelength region of the light emitted from the first light emitting device. The circuitry further reads embedded information based on a reading result obtained in an imaging device that receives the light emitted from the selected at least one of the first light emitting device and the second light emitting device and reflected by an authentication medium. The embedded information includes information for authentication, and is embedded in the authentication medium and obtained with light in a range of light receiving sensitivity of silicon forming the imaging device.

摘要： An information processing apparatus includes circuitry. The circuitry transmits document data in response to a request signal transmitted from an information processing terminal and requesting output of the document data. Based on an information signal transmitted from the information processing terminal and indicating information that is not described in a document indicated by the document data, the circuitry generates latent-image data as a latent image including the information signal and the document data. The circuitry outputs the latent-image data and the document data.
