The technology described implements attestation programs that employ 'code reuse' techniques. In particular, the technology relates to auto-generating attestation programs for, among other aspects, detecting whether a program has been modified. In one non-limiting example, the technology uses a tool that scans a software program (e.g., a video game) code for usable code sequences. The tool can automatically combine code sequences to generate a large number of attestation programs of different variety (e.g., memory checks, hashing).

Systems and method for identifying modified program data

An information processing system is capable of communicating with an external apparatus via a network. The information processing system is capable of operating in at least three operation modes including: a first mode; a second mode, which consumes less power than the first mode; and a third mode, which consumes less power than the second mode and where the communication via the network is not performed. The information processing system includes a mode control section and a second mode processing section. The mode control section, when the information processing system operates in the third mode, shifts the operation mode to the second mode periodically or in accordance with a predetermined time schedule. The second mode processing section performs a communication process via the network as information processing in the second mode.

Information processing system, information processing apparatus, information processing program, and method of controlling operation mode

An object is to provide an information processing apparatus and the like that can reduce power consumption of the information processing apparatus in downloading and installing. To achieve this object, whether or not there is system software update is confirmed in a low power consumption state in which only some of hardware components of the information processing apparatus are supplied with power and communication with a predetermined server can be performed. When there is the update, update data is downloaded, and at least some of the hardware components that are the update targets and that are not supplied with power in the low power consumption state are started to be supplied with power. Then, system update is executed. The series of processes are automatically executed without a user's operation.
