[Partial Translation Japanese ŁŁ English K01000331A1] 5 10 15 20 Data Terminal Device [Name of the Invention] [Claim 1] A data terminal device that obtains encrypted contents data from a recording medium containing the encrypted contents data and a server information file that is necessary to obtain a license for reproducing said encrypted contents data, and that obtains said license from a distribution server in accordance with said server information file, the data terminal device comprising: a medium driving portion that obtains said encrypted contents data and said server information file from said recording medium; a control portion that determines a connection means for connecting to said distribution server in accordance with the content of the server information file obtained by said medium driving portion, that connects to said distribution server with the determined connection means to request distribution of said license, and that receives said license from said distribution server; a storage portion storing the encrypted contents data obtained by said medium driving portion; and a device portion storing the license that has been received from said distribution server. 1
Abstract [Document Name] [Abstract] [Problem] To provide a data terminal device that, to obtain encrypted contents data from a recording medium, obtains a license for reproducing the encrypted contents data. [Means to Solve the Problem] A personal computer copies encrypted contents data, contents files 601 to 60n, and a server information file from a CD–ROM to a hard disk 530, requests a distribution server to distribute a license for the encrypted contents data in accordance with an access means and an address of an access target included in the server information file, and receives a license. Then, the received license is stored in a license area 5215B of a memory of an internal license administration device 520. [Selected Drawing] Fig. 18 5 10 15 2
[Partial Translation Japanese ŁŁ English K01000341A1] 5 10 15 20 Data Terminal Device [Name of the Invention] [Claim 1] A data terminal device that obtains encrypted contents data, made of contents data that have been encrypted, and a license for obtaining original plain data by decrypting said encrypted contents data, and that outputs said encrypted contents data and said license to another data terminal device, the data terminal device comprising: a module portion that obtains said encrypted contents data and said license by software; a storage portion that stores said encrypted contents data, a license administration file, and an encrypted secret file; and a device portion that decrypts said encrypted secret file, and stores in a special area a binding license including a binding key that encrypts the decrypted secret file; wherein the secret file comprises secret information having said license as a structural element; and wherein said file comprises an administration number of said secret information that corresponds to said encrypted contents file and that is included in said secret file. license administration 3
Abstract [Document Name] [Abstract] [Problem] To provide a data terminal device that can move, to another data terminal device, encrypted contents data and a license that have been distributed by software. [Means to Solve the Problem] A hard disk 530 of a personal computer has a contents list file 150 and an encrypted secret file 160. A license administration device 520 stores a binding key Kb in a license area 5215B of a memory. The encrypted secret file 160 can be decrypted and encrypted with the binding key Kb that is stored by the license administration device 520. A license for encrypted contents data that has been obtained is stored as secret information in the encrypted secret file 160. [Selected Drawing] Fig. 25 5 10 15 4
[Partial Translation Japanese ŁŁ English K01000351A1] Data Terminal Device [Name of the Invention] [Claim 1] A data terminal device that obtains encrypted contents data, made of contents data that have been encrypted, and a license for obtaining original plain data by decrypting said encrypted contents data, and that administrates said encrypted contents data and said license, the data terminal device comprising: a device portion for obtaining said encrypted contents data and said license at a first security level, and for administrating said license at said first security level; a module portion for obtaining said encrypted contents data and said license at a second security level that is lower than said first security level, and for generating an exclusive license made by subjecting said for administration at said second security level; a storage portion for storing data; and a control portion; wherein said device portion comprises a storage portion storing license to an encryption that is suitable said license in association with an administration number; wherein said storage portion comprises a plurality of encrypted contents data; a plurality of first administration files comprising an administration number that corresponds to a license administrated by said device portion; a plurality of second administration files comprising said exclusive license; and a contents list indicating the relation between said first and second administration files and said encrypted contents data; and wherein said control portion, if a license has been obtained at said first and second security level, generates said first and second administration first and second administration files and said obtained encrypted contents data into said storage portion, and passes a license obtained at said first security level to said device portion. the generated files, writes 5 10 15 20 25 30 35 40 5
5 10 Abstract [Document Name] [Abstract] [Problem] To provide a data terminal device that can administrate encrypted contents data of different security levels in accordance with the security level. [Means to Solve the Problem] A contents list file 150 includes contents files 1531 to 1535 and license administration files 1521 to 1525. The contents files 1531 to 1535 record file names of encrypted contents data {Dc}Kc and supplementary information Dc–inf that have been received at different security levels. Moreover, the license administration files 1521 to 1525 are recorded in correspondence to the respective contents files 1531 to 1535, and administrate the licenses that have been received at the different security levels.

[Partial Translation Japanese ŁŁ English K01000361A1] Data Terminal Device [Name of the Invention] [Claim 1] A data terminal device that obtains unencrypted contents data, and that generates encrypted contents data, made of said contents data that have been encrypted, and a local license for decrypting and reproducing said encrypted contents data, the data terminal device comprising: an encrypted contents generation means for generating said local license based on duplicability information included in said contents data, and generating said encrypted contents data by encrypting said contents data with a license key that is included in the generated local license; an encryption process means for generating an encrypted local license made by subjecting the generated local license to a unique encryption; a storage means for storing said encrypted local license and the encrypted contents data; and a control portion; wherein said control portion passes said obtained contents data to said encryption contents generation means, and passes said local license to said encryption process means. 5 10 15 20 25 7
Abstract [Document Name] [Abstract] [Problem] To provide a data terminal device that can rip contents data in accordance with a usage regularity of the contents data. [Means to Solve the Problem] A watermark detection means 5400 detects a watermark from music data, and a watermark decision means 5401 decides whether there is a regularity in the usage regulations of the detected watermark.1 Then, a license generation means 5403 generates a license in accordance with the usage regularity of the watermark. A remarking means 5402 replaces the watermark with one in which the duplication condition of the music data has been modified in accordance with the usage regularity of the watermark. A music encoder 5404 encodes the music data from the remarking means 5402 in a predetermined format. An encryption means 5405 encrypts the music data from the music encoder 5404 with a license key generated by the license generation means 5403.
