- the user downloads the content desired to be purchased from the distribution source by clicking on the icon of the content desired to be purchased from the content targeted for the distribution service displayed on the display.
- the IP address on the network of the distribution source that receives the distribution is written on the disk, and the user only has to insert the disk into the disk drive device, and the distribution source password and the like are not required. Without any I ⁇ , it will be delivered to the distributor. In this way, the disk can be accessed directly as the physical passport without the DNS (domain name server) being stored (no need to enter a password, etc.), so it is not secure.
- the operation is very simple and operability is high.
- Personal information uses an electronic circuit mounted on a disk and is stored in a memory controlled and specified by the electronic circuit. Easy from! It can't be released and has high security 3 ⁇ 4S. Furthermore, since the disk controls an external device such as a biometric authentication device itself, it is possible to authenticate the user with certainty and effectively prevent unauthorized access.
- At least two pieces of data are used to generate content data, one data is stored on a disk, and the other data is stored on a server side via a network.
- these divided data are combined to obtain the original content data, and the original content data can be obtained only by copying the disk via the Internet. Not complete It is extremely difficult to acquire content data, and it is possible to more securely perform rights.
- content data such as music and movies purchased via the Internet is downloaded and saved in a memory such as an HDD that has been printed on a computer.
- the “touch” part is missing from the downloaded content data, and noise is embedded.
- To play content such as music and movies insert a disc into the disc drive device, and then store the disc storage area, the data stored in the disc and the data stored in the memory (such as the “touch” part above).
- the content data that is not stored on the HDD is acquired) and integrated (combined) with the data from the HDD, to obtain complete content data and play music and movies.
- a part of “touch” video and audio may be recorded in the storage area of the optical disc, and a part of “sawayari” audio (such as important lines) may be recorded in the memory of the electronic circuit unit. it can.
- streaming is used instead of downloading.
- the disk can access the target IP address directly without using a DNS (domain name server) (it is safe because it does not require an input of a password, etc. Easy).
- DNS domain name server
- Individual 1 mfg (credit card number, bank account, ID code, etc.) is a disk with an electronic circuit and is protected by a high security function.
- the external circuit / device such as the biometric authentication device is controlled by the electronic circuit of the optical disc, the user authentication can be performed more reliably and unauthorized access can be prevented more effectively. It can be carried out.
