An information processing apparatus has a deployment unit configured to deploy an image file and to create files used for a virtual environment, a virtual environment creator configured to create the virtual environment using the files, a recorder configured to record information about a first file included in the files, a manager configured to access the first file stored in the virtual environment and to determine, based on information acquired by accessing the first file, whether to execute software whose execution was detected in the virtual environment, and a normality determinator configured to determine, based on a difference between information acquired by accessing the first file and information about the recorded first file, whether the first file is normal.

Information processing apparatus, information processing method, and recording medium

An information processing apparatus includes one or more managers that manage one or more virtual environments, and a management controller that controls the one or more managers. When the execution of the software is detected in any of the one or more virtual environments, the management controller instructs the manager that manages the detected virtual environment to determine whether to execute the software in the detected virtual environment. The manager reads a file stored in the detected virtual environment, and determines whether to execute the software in the detected virtual environment based on information indicated in the file.

An information processing system includes an edge server and a low-end device. The edge server has a storage and a processor. The low-end device has a storage and a processor, connected to the edge server. The processor of the low-end device transmits abnormality information for detecting its own abnormality to the edge server, the storage of the edge server stores information on the software. The low-end device information includes the version of the software. The processor of the edge server detects an abnormality in the low-end device based on the abnormality information, acquires version information of the software, acquires information on rollback software which is a version of software older than a version in the version information of the software running in the low-end device from the storage, and requests the low-end device to roll back the software based on the information on the rollback software.

The present invention provides a method of producing phosphoric acid crosslinked starch, including adding phosphorus oxychloride sequentially to raw starch slurry under a condition of pH 9 to 12 to cause the raw starch to undergo a phosphoric acid crosslinking reaction, and controlling the pH by sequentially adding an alkaline solution, wherein concentration of the alkaline solution is increased stepwise or continuously between start and end of the phosphoric acid crosslinking reaction. By the production method of the present invention, phosphoric acid crosslinked starch having a low phosphorus content and a high resistant starch content (for example, pea-derived phosphoric acid crosslinked starch, which has a resistant starch content of 80% or more according to a resistant starch measurement method of AOAC official method 2002.02 and a phosphorus content of 0.5% or less) can be obtained.

Method of producing phosphoric acid crosslinked starch

A terminal device according to an embodiment includes an accepting unit, a secret value generating unit, a response data generating unit, and an output unit. The accepting unit accepts an inquiry about genome data of each user. The secret value generating unit generates a secret value by applying a one-way function to the genome data. The response data generating unit generates response data to the inquiry on the basis of the secret value generated by the secret value generating unit and contents of the inquiry. The output unit outputs the response data generated by the response data generating unit.

According to one embodiment, the resource access unit accesses a first resource including a replication target object and policy data assigned to the object. The policy data includes base policy data including a first condition and assertion policy data including a second condition. The first retrieval unit obtains first attribute data for accessing the first resource. The first policy evaluation unit determines whether the first attribute satisfies the first condition. When the first condition is satisfied, the copy processing unit executes the copy processing for copying the object. The second retrieval unit obtains the second attribute data for accessing the second resource. The second policy evaluation unit determines whether the second attribute data satisfies the second condition. When the second condition is satisfied, the paste processing unit executes paste processing for pasting the object to the second resource.

Method and apparatus for controlling replication processing of object

In each stage, multiple parallel nonlinear transformation modules each perform local lower-level diffusion, then a diffusion module performs higher-level diffusion over the block width and multiple parallel nonlinear transformation modules each perform local lower-level diffusion. This operation is repeated a predetermined number of times corresponding to the number of stages. Each nonlinear transformation module is formed into the nested SPN structure by arranging alternately nonlinear transformation modules and a diffusion module. The diffusion module performs linear transformation for spreading the state of at least one bit in input data to the preceding nonlinear transformation modules to at least one bit in input data to the succeeding nonlinear transformation modules.
