Abstract:
The present technology relates to an information processing device and method and a program capable of efficiently protecting sufficient security. An information processing device includes a communication unit that transmits information regarding security of the information processing device and receives designation information indicating processing to be performed for security protection, transmitted in response to the transmission of the information regarding the security and a control unit that performs the processing for security protection on a basis of the designation information in a case where the control unit transmits data to a predetermined device or in a case where the control unit receives data transmitted from the device. The present technology is applicable to a healthcare IoT system.
Abstract:
To perform high-speed and efficient processing of determining a correlation between vectors. An information processing system includes: a first information processing device having k number of vectors including secure data as an element; and a second information processing device having m number of vectors including secure data as an element. The first information processing device receives vector information regarding a vector Y selected from the m number of vectors, as encrypted data, from the second information processing device. A data processing unit of the first information processing device sequentially calculates element-based sample identifiers each having a specific common value for each of a plurality of different vectors Y selected from the m number of vectors to one vector X selected from the k number of vectors retained by the first information processing device, and sequentially determines the correlation between the one vector X and each of the plurality of different vectors.
Abstract:
There is provided an information processing apparatus including a first computation protocol generation unit configured to generate a first computation protocol that does not include a confidentiality securing protocol that is executed in order to maintain confidentiality of a plurality of input values on the basis of a secure computation protocol in which a plurality of operation processing apparatuses compute an output value on the basis of the input values, and a second computation protocol generation unit configured to generate a second computation protocol by arranging the confidentiality securing protocol to a position at which the confidentiality is secured in the first computation protocol.
Abstract:
[Object] To provide an environmental measurement apparatus that detects a fine particle in the air such as smoke or an odor and can be made small, an information processing apparatus that uses measurement data acquired using the environmental measurement apparatus, an information processing system, an information processing method, and a program. [Solving Means] An environmental measurement apparatus includes a light source and a light-receiving-element array. The light source irradiates light onto a fine particle in gas. The light-receiving-element array includes a plurality of light receiving elements receiving backscattered light obtained by the light being irradiated onto the fine particle.
Abstract:
To achieve high-speed and efficient parameter calculation processing of a logistic regression model. A logistic regression parameter is calculated, the logistic regression parameter being a parameter of the logistic regression model indicating the relationship between an explanatory variable and an outcome variable being secure data corresponding to each sample. A data processing unit calculates the inner product (t_s) of the explanatory variable and the outcome variable with application of secure computation being computation processing applied with converted data of each of the variables, and performs computation processing excluding the calculation processing of the inner product, as computation processing without the converted data, to calculate the logistic regression parameter in accordance with the maximum likelihood method with the Newton-Raphson method (iterative convergence method).
