Abstract:
An information processing apparatus includes a calculation unit and a generation unit. The calculation unit is configured to calculate a frequency function which is a function relating to an appearance frequency of one or more attribute values of a database having a predetermined attribute and the one or more attribute values relating to the attribute. The generation unit is configured to generate sample data in accordance with the appearance frequency relating to the database on the basis of the frequency function calculated, the sample data including at least a part of the one or more attribute values as one or more sample attribute values.
Abstract:
[Object] To provide an information processing apparatus through which a safe and convenient user authentication mechanism is implemented according to a public key authentication scheme.[Solution] There is provided an information processing apparatus including a memory configured to retain a first secret key corresponding to a first public key, and a processor configured to request a change of a usage state of a second public key registered by a second apparatus in a first apparatus configured to retain a public key corresponding to a secret key from the first apparatus according to authentication using the first public key associated with the second public key and the first secret key.
Abstract:
There is provided an information processing apparatus which is capable of encouraging behaviors that have an effect appropriate for the body of a measured person in accordance with the physical condition of the measured person. The information processing apparatus includes: a comparing section configured to perform a comparison using a blood flow velocity of a measured person in a predetermined state and a blood flow velocity of the measured person in a state other than the predetermined state; and an information presenting section configured to present information corresponding to a comparison result of the comparing section.
Abstract:
There is provided an information processing apparatus, an information processing method, and a program capable of obtaining accurate blood flow information while suppressing power consumption. The information processing apparatus includes: an estimation unit configured to estimate another kind of blood flow information associated with one kind of blood flow information from the one kind of blood flow information obtained through blood flow measurement on the basis of relation information indicating a relation between the two different kinds of blood flow information.
Abstract:
There is provided an information processing device including an acquisition unit that acquires a first word input by a user, and a presentation unit that presents second words for replacing the first word when the first word is acquired by the acquisition unit.
Abstract:
Value of data D based on a data value examination criterion C is determined through secure calculation without input data D and the data value examination criterion C being disclosed to each other. Secure calculation is executed without a data providing device disclosing the input data D to a data collecting device, and further, without a data collecting device disclosing the data value examination criterion C to the data providing device. The data providing device generates one piece of distributed information rp of a data value index value which is a calculation value of a data value calculation function f(D, C) of the input data D through secure calculation and calculates the data value index value through operation of the generated distributed information rp and another piece of distributed information rc of the data value index value received from the data collecting device.
Abstract:
To be capable of guaranteeing security without dependency on a distance of wireless communication while maintaining convenience of a key apparatus, there is provided an information processing apparatus including: a key storage unit configured to retain one or more secret keys corresponding to one or more respective public keys; and a key use permission state storage unit configured to store presence or absence of use permission of each of the one or more secret keys. For at least any of the one or more secret keys, a switch between the presence and absence of the use permission stored by the key use permission state storage unit is possible.
