摘要： A data generation apparatus includes a processor that executes a process including obtaining target data sequentially from time-series data, the target data including n (n being an integer greater than or equal to 2) data items in a predetermined section of the time-series data, calculating parameter information satisfying a (k−1) order polynomial based on the target data, the (k−1) order polynomial including k random values, k being an integer greater than or equal to 1 and less than n, associating the target data to the parameter information, outputting the target data and the parameter information associated to the target data, attaching a signature to secret information based on a secret distributed protocol. The secret information is calculable by using k pairs of data including the target data and the parameter information associated to the target data, and outputting the secret information attached with the signature.

摘要： A data processing apparatus includes a memory storing a program and a processor configured to execute the program to implement a process of reading signed data including a predetermined number (n) of secret sharing data sets generated for each section of time series data and a signature value calculated for the each section of time series data based on a secret sharing protocol. The n secret sharing data sets include n units of data acquired from each section of time series data and parameter information for a polynomial of a predetermined degree calculated based on the acquired n units of data. The processor further implements processes of acquiring the predetermined degree, and editing the signed data by extracting a specific number of the secret sharing data sets from the n secret sharing data sets for the each section of time series data according to the acquired predetermined degree.

摘要： A data management system includes a detecting apparatus that detects an information processing apparatus and a server apparatus that controls access to data by the information processing apparatus. The detecting apparatus detects the information processing apparatus located within a predetermined area. The server apparatus includes a transmitter that transfers data to the detected information processing apparatus, the data being associated with access authority indicating whether or not the information processing apparatus is allowed to access the data, and circuitry that controls an access to the data from the detected information processing apparatus in accordance with the access authority associated with the data.
