A personal identity authenticating system where the registrant/cardholder and the registrar are assigned specific identifiers and secret keys and public keys that are mapped to the identifiers at the authentication support station (ASS). Personal identity to which the registrar identifier is attached is encrypted wit the registrant/cardholder's secret key. Personal identity data is embedded as an encrypted watermark image data by means of the registrar's secret key. Both encrypted identity and watermarked image data are recorded on the IC card. When authentication is required, the identity data with the registrar identifier is decrypted with the cardholder's public key that is supplied by the ASS. The registrar's public key is obtained from the ASS by using the decrypted registrar identifier. The registrar's public key permits the personal identity to be retrieved from the watermarked image data. Internal authentication is executed by matching between personal identity strings and image data.

Apparatus, system, and method for authenticating personal identity, computer readable medium having personal identity authenticating program recorded thereon, method of registering personal identity authenticating information, method of verifying personal identity authenticating information, and recording medium having personal identity authenticating information recorded thereon

An image capturing device includes an image capturer, operable to perform a first image capturing of an object image so as to generate first image data corresponding to a first time period shorter than a predetermined time period, and operable to perform a second image capturing of the object image so as to generate second image data corresponding to a second time period shorter than the predetermined time period, a storage, adapted to store the first image data and the second image data, and an image generator, operable to generate image data corresponding to the predetermined time period based on the first image data and the second image data.
