A program execution device capable of protecting a program against unauthorized analysis and alteration is provided. The program execution device includes an execution unit, a first protection unit, and a second protection unit. The execution unit executes a first program and a second program, and is connected with an external device that is capable of controlling the execution. The first protection unit disconnects the execution unit from the external device while the execution unit is executing the first program. The second protection unit protects the first program while the execution unit is executing the second program.

A mobile robot that autonomously travels includes a body that has a front surface, a driver that is disposed in the body and that drives travelling of the body, a base that includes a spring and that is connected to the body via the spring, and a distance measurer that is disposed at an upper part of the base. The base is connected to the body in such a way that the base is movable to be in a first state in which the laser range finder is located inside the body and a second state in which the laser range finder is located outside the body. The spring generates a force that pushes the base from a front surface of the body to an outside of the body.

A cleaning robot includes an arm including a distal end portion to which a brush is attached, the arm extending in a first direction parallel to a horizontal direction, a driver connected to the arm, the driver including a first mechanism that moves the arm in the first direction, a second mechanism that moves the arm in a second direction parallel to a vertical direction perpendicular to the first direction, and a third mechanism that moves the arm in a third direction perpendicular to both the first direction and second direction, a controller configured to switch the orientation of the distal end portion between an orientation for cleaning a first target face of the object and an orientation for cleaning a second target face of the object, the first target face facing the first direction, the second target face facing the second direction.

An audio object (AOB) for which corresponding rights management information (RMI) has been generated by a license management apparatus, and an AOB for which RMI does not exist are written into a recording medium for use in an SDMI system which includes the license management apparatus. Each AOB is put in correspondence with a migration permission flag (MPF). When the corresponding AOB is the AOB for which RMI does not exist, the relevant MPF is set to on so as to show that a migration procedure is permitted. When the corresponding AOB is the AOB for which RMI has been generated by the license management apparatus, the relevant MPF is set to off so as to show that a migration procedure is not permitted.

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.

Content reproduction system, information processing terminal, media server, secure device, and server secure device

An information processing apparatus that processes data to be protected is provided. The information processing apparatus includes a first storage unit, a second storage unit, and a cache control unit configured to cache data stored in the first storage unit into the second storage unit. The cache control unit is configured to lock a cache region in the second storage unit to thereby prevent cache data of the stored data from being written back into the first storage unit, the cache data being obtainable from the cache region in the second storage unit in which the stored data is cached, and write the data to be protected different from the stored data into the cache region in the second storage unit, after the cache region in the second storage unit is locked.
