摘要： The present invention makes it possible to use data that is held by a given terminal device in another terminal device, even after the given terminal device can no longer be accessed externally. If a terminal device 100a detects an event wherein one's own terminal will no longer be externally accessible, then the data held by one's own terminal 100a is transferred to another device 200 that can be accessed externally. Another terminal device 100b, which acquires and uses data, acquires data from the device 200, and uses such.

摘要： A personal information management device aims to save troubles of inputting passwords and deleting personal information, to prevent others from viewing the personal information, and to maintain confidentiality of the personal information even when a mobile device is lost. Personal information storage unit 201 holds encrypted personal information, key distribution unit 204 distributes a decryption key used for decrypting the encrypted personal information into a first and a second distributed keys based on a secret sharing scheme, distributed key storage unit 205 stores thereon the first distributed key, stores the second distributed key on home device 30, and deletes the decryption key. Upon decryption, link judgment unit 210 judges link establishment. Key recovery unit 207 acquires the second distributed key from home device 30, and recovers the decryption key using the first and the second distributed keys. Decryption unit 208 decrypts the encrypted personal information using the decryption key.

摘要： An image processing apparatus enables image data to be handled easily after photography. A server apparatus pattern images and control information in correspondence with user identifiers. A digital camera photographs a subject, obtains a pattern image and a piece of control information from the server apparatus, and judges whether a portion of the image data obtained by photography matches the obtained pattern image. If a matching portion exists, the digital camera operations in accordance with an operation instruction included in the piece of control information. If the operation instruction is mosaic processing, the digital camera performs mosaic processing to the matching portion. If the operation instruction is image replacement, the digital camera replaces the matching portion with a predetermined image or performs CG processing on the matching portion. If the operation instruction is frame deletion, the digital camera deletes the image data.

摘要： A content reproduction system includes an information processing terminal and a secure device. The information processing terminal receives a copyright protection application program from an application distribution server. The copyright protection application program includes a first program having a first execution format executable in the information processing terminal and a second program having a second execution format different from the first execution format and executable in the secure device. The second program is encrypted with a program key held in the secure device. By extracting and executing the first program, the information processing terminal extracts the second program and transmits the second program to the secure device. The secure device receives the second program from the information processing terminal, decrypts the second program using a program key stored in a key storing unit, and executes the second program.
