When a user gets interested in some music he/she listens to somewhere, for example, in a coffee shop, the user records that music in a memory provided in a portable terminal. A processor reads the information recorded in the memory and performs a predetermined process on it. The resultant information is stored on a storage device. The information stored on the storage device is then transferred to a remote server via a communication device. The remote server searches the database for the title of the music corresponding to the received information and returns the results to the terminal. Thus, the user can easily get information about the title of the music.

Information processing apparatus and method, information processing system, and transmission medium

A user information processing method, an apparatus thereof and a user information processing system in which personal information can be more effectively employed. Terminal use record information is obtained when a user employs terminal units. The profile information of the user is generated on the basis of the accumulated terminal use record information and the generated profile information is stored, so that information peculiar to the user can be provided on the basis of the stored profile information of the user.

Thus, the user can easily get information about the title of the music and the singer's name.

A management apparatus includes a registering unit configured to issue a first key corresponding to a first service in response to a request for registration with the first service from a first information processing apparatus; a storage unit configured to store an apparatus ID of the first information processing apparatus, the first key, and a second key corresponding to a second service while associating the apparatus ID, the first key, and the second key with each other; and a composite license issuing unit configured to issue a composite license including a first license and a second license, the first license including first encrypted data, which is a content key that is used to decrypt the encrypted content and that is encrypted with the first key, and the second license including second encrypted data, which is the content key that is encrypted with the second key.

Management apparatus, information processing apparatus, management method, and information processing method

A content information providing system is disclosed which can protect the copyrights of contents while permitting users who do not purchase the contents to utilize the contents. A content information providing server includes a user information storage section for storing a user key unique to each user, a content key storage section for storing content keys unique to individual contents, a recommendation section for selecting a content to be recommended to the user, a content key encryption section for encrypting the selected content key with a user key of the user of a target of the recommendation, and a content information sender section for transmitting the encrypted content key to a content reproduction apparatus used by the user. The content reproduction apparatus includes a content information receiver section for receiving the content key, and a content key decryption section for decrypting the encrypted content key.

Content information providing system, content information providing server, content reproduction apparatus, content information providing method, content reproduction method and computer program

A method for monitoring time so that the use of protected content can be controlled includes receiving a trusted time value from a trusted authority external to a client device. When the client is no longer in communication with the trusted authority, the previously-received trusted time value is updated by use of the client's operating system counter so that a calculated trusted time value is derived for content license evaluation purposes.

Digital rights management using trusted time

Information of a terminal equipment used by a user among the pieces of terminal equipment connected to a network is registered in prescribed registering means and a transmission path from the terminal equipment of a transmitter to the terminal equipment of a receiver is determined based on the registered information of the terminal equipment, so that the user can assuredly transmit the information to the terminal equipment of the receiver in the transmission path suitable for the information without any consciousness of the user. The information of the terminal equipment used by a user and the terminal equipment connected to the terminal equipment used by the user among the pieces of terminal equipment connected to the network is registered in prescribed registering means together with information for identifying the user as available environmental information, and provided information is transmitted to the terminal equipment specified by the registered available environmental information.

Communication system, network system, information controller and terminal equipment

The present embodiments advantageously provide methods and systems for use in decrypting content, and in some preferred embodiments expanding a security environment to distribute the computational processing involved in decryption. In some embodiments, a method for use in decrypting content is provided that receives a first content key at a first system for the decryption of a first track of encrypted content; encrypts the first content key according to a first instance key known at the first system; communicates the first encrypted content key over an externally accessible communication link to a second system; generates the first instance key at the second system independent of the first system; decrypts the first encrypted content key using the generated first instance key at the second system; and decrypts the first track of encrypted content using the first unencrypted content key at the second system.

Method, apparatus and system for use in distributed and parallel decryption

The present invention relates to an information processing apparatus, an information processing method, a recording medium, and a program for importing and exporting a content with information missing controlled. A CPU extracts a sound track contained in the content in step S, and converts a format of the extracted sound track into a format compatible with a memory stick in step S. The CPU generates a predetermined file from data contained in the content and excluding the sound track in step S. In step S, the CPU attaches reference information of the sound track to the file. In step S, the CPU controls the writing of the sound track in the converted format and the file to the memory stick. The present invention is applied to clients of a DRM system.
