In an information processing device, a fluctuation estimation unit acquires from a noise source a plurality of measured values having bits of M digits, where M is an integer exponent of a power of two. A bit extraction unit acquires information relating to a number of effective bits of N digits used in generating a random number, where N is an integer less than M, based on the acquired plurality of values. Using the information relating to the number of effective bits, a bit coupling unit generates a random number having effective bits of L digits, where L is a predetermined integer greater than or equal to N.

Random number generation device, information processing device, and random number generation method

A terminal exchanges a common key generated using a seed, the randomness of which was recognized in advance, with a verification server. The terminal generates verification data using a plurality of measured values from a noise source. The terminal encrypts the verification data with the common key and transmits the verification data to the verification server. The verification server verifies the randomness of verification data obtained by decrypting the encrypted verification data with the common key. When it is determined that the verification data has randomness, the verification server transmits a verification result indicating that the randomness of the verification data is recognized to the terminal. The terminal acquires a plurality of measured values and generates a new seed in accordance with the verification result from the server and preserves the new seed in a secure area.

Randomness verification system and method of verifying randomness

A resolution converter converts input image data to N types (N is a plural number) of image data having resolutions different with each other. A secret sharing unit performs secret sharing schemes so that the plurality of pieces of image data are respectively divided into n pieces (n is an integer equal to or more than N+1 and the same value in all of image data) of distributed data and the distributed data is reconstructed to original image data using k pieces (k is an integer equal to or more than 2 and equal to or less than n and different value for each piece of image data) among n pieces. A data combination unit generates n pieces of combination data by combining distributed data selected one by one so as not to overlap with each of resolutions and stores each piece of the combination data in different storages. As more pieces of distributed data are gathered, image data with higher resolutions can be reproduced and security for copyright, privacy, or the like can be secured in each piece of distributed data.

Management device and image processing system

A communication system includes a first communication apparatus and a second communication apparatus. The first communication apparatus includes a partial image data generation unit, configured to generate partial image data which is obtained by extracting a partial component from image data, and a transmission unit, configured to transmit the partial image data generated by the partial image data generation unit to the second communication apparatus. The second communication apparatus includes a reception unit, configured to receive the partial image data transmitted by the transmission unit of the first communication apparatus.
