A semiconductor light-emitting element of a metal/organic film/semiconductor junction structure has a semiconductor layer, and an organic Langmuir-Blodgett thin film formed on the semiconductor layer. The thin film includes an electron donative organic monomolecular compound whose longest absorption peak wavelength in an electron transition spectrum falls within a range of 300 nm to 600 nm. A layer of metallic material is formed on the thin film.

To reduce a load on a user terminal imposed when verifying signature data and at the same time reduce a load on a server, a signature key matrix KM includes a plurality of signature keys Ki-j arranged in a matrix structure of m rows and n columns, and is stored in a signature key matrix database 21. A correspondence relationship between a signature key set CK which is an aggregate of any signature keys selected from the n columns respectively and a user terminal 30 is stored in a correspondence relationship information database 22. A signature data generating unit 24 generates signature data having a matrix structure by encrypting a content digest D generated based on content data C by n number of signature keys included in the signature key matrix KM.

This data protection system encrypts and stores data in a memory card, using a double encryption key scheme for encrypting the data with a data key and further encrypting the data key with a user key. This system provides data to a particular host device from the memory card and limits provision of the data to other host devices. The host device includes DPS program that governs control of writing data to, and reading data from the memory card. The memory card includes a first non-volatile memory and a memory controller that controls the first non-volatile memory. DPSA program is implemented in the memory controller that manages ID information for identifying a user capable of decrypting the encrypted data with the user key.

An optical transmitter is provided for transmitting a wavelength multiplexed signal comprising an intensity modulation optical signal and a phase modulation optical signal through a transmission line. The optical transmitter includes a bit time difference given signal generator for generating at least two optical signals having a bit time difference therebetween, from the wavelength multiplexed signal.

Provided is a surgery assistance system to perform relatively fast and accurate alignment between three-dimensional surface shape data acquired by measurement using a three-dimensional surface shape scanner and three-dimensional internal shape data acquired in advance, even when the position of the patient and the surface shape of the skin of the patient change during the surgery. A surgery assistance system (1) includes a three-dimensional surface shape scanner (20) for acquiring three-dimensional surface shape data by measuring a three-dimensional surface shape of a patient (60) and a computing device (40) for processing the data from the three-dimensional surface shape scanner. The computing device stores therein three-dimensional internal shape data of the patient that is acquired in advance by measurement using a three-dimensional tomography scanner (30). The computing device has a unit that aligns the three-dimensional internal shape data and the three-dimensional surface shape data with each other by using data of a portion where a distance between a skeleton and a skin surface is small in the three-dimensional internal shape data and three-dimensional surface shape data corresponding to this portion.

A user terminal converts stored contents of an SD card to contain second encrypted content key data equivalent to an encrypted title key of SD Audio, and encrypted content equivalent to encrypted content of the SD Audio. Accordingly, compatibility can be realized between an encryption dual key system as a first encryption system and an encryption (single) key system as a second encryption system.
