An information processing apparatus includes a processor that detects positions of ball candidates from a plurality of time-series image frames. The processor adds a position of a second ball candidate to a second image frame subsequent to a first image frame based on a position of a first ball candidate and movement definition information. The first ball candidate is detected from the first image frame. The movement definition information defines a characteristic of a movement of a ball. The processor generates a plurality of trajectory candidates by combining a plurality of ball candidates detected from image frames of different times. The processor evaluates the plurality of trajectory candidates to determine a ball trajectory. The processor interpolates, when the ball trajectory is interrupted, between a starting point and an ending point of the interruption with a trajectory of a first person who moves from the starting point to the ending point.

A verification devicereceives extracted and sanitized datathat has been sanitized to protect the privacy of person A. The verification device, extracts from among MCU-hash storage dataand for MCUand MCUamong MCUs obtained by dividing the extracted and sanitized data, an MCUhash and an MCUhash. The verification devicegenerates an MCUhash to an MCUhash and from the MCUhash to the MCUhash, generates a JPEG frame hash. The verification device 101 then compares a JPEG hashand the JPEG hashto verify the authenticity of the extracted and sanitized data

Verification method, verification device, and computer product

Each of a plurality of encoders calculates a first time by adding an encoding delay time commonly determined between the encoders to a value of an STC counter, and transmits a system stream generated by including the calculated first time to a decoder associated with the encoder in one-to-one correspondence, of a plurality of decoders constituting a decoding system. Each of the decoders calculates a second time by adding the first time to an estimated maximum value commonly determined between the decoders by adding a decoding delay time to a value of stream fluctuation of an output time occurring between the encoders, and outputs the divided image data decoded from the system stream to a synthesizer that synthesizes the image data at the calculated second time.

Encoding/decoding system, encoding system, and decoding system

A small-scale wireless communication system offering advanced security level. An encryption key memory of an access point stores an encryption key list of a plurality of different encryption keys. A change information transmitter periodically transmits change information to a terminal by radio, the change information requesting the change of encryption key. An encryption key selector selects an encryption key from the encryption key list under a rule when the change information transmitter transmits the change information. A terminal-side encryption key memory of the terminal stores a terminal-side encryption key list which is the same as the encryption key list. A change information receiver receives the change information from the access point. Upon reception of the change information, a terminal-side encryption key selector selects an encryption key from the terminal-side encryption key list under a rule which is the same as the rule which the encryption key selector used to select the encryption key.

Wireless communication system

A wireless communication apparatus capable of preventing data leakage in wireless communication. A transmitted data frame receiver receives a transmitted data frame which is transmitted from a terminal to the wireless communication apparatus. An address information converter converts the address information of the terminal included in the transmitted data frame, into the address information of the own wireless communication apparatus. A radio transmitter transmits the transmitted data frame by radio. An address information comparator compares the address information included in a received data frame received by a radio receiver, with the address information of wireless communication apparatuses being stored in an address information memory. A received data frame destruction unit destructs the received data frame depending on the comparison result.
