The present disclosure aims to provide a backdoor inspection device, a user device, a system, a method, and a non-transitory computer-readable medium that can increase trustability of software as to whether or not there is a backdoor in the software. A system according to the present disclosure includes: a plurality of backdoor inspection devices; a plurality of databases; and a user device, in which the backdoor inspection device includes: a backdoor presuming means for performing backdoor inspection on a prescribed software installed in a counterpart device that communicates with the user device and presumes whether or not there is a backdoor in the prescribed software; a certificate issuance means for issuing a backdoor inspection certificate including a result of the backdoor inspection, the database includes: a registration means for registering the backdoor inspection certificate; and a transmission means for transmitting the backdoor inspection certificate.

System, method, and non-transitory computer-readable medium

A program analysis device including: code block extraction means for extracting code blocks having specific qualities from code blocks included in binary data of a program; backdoor score calculation means for calculating, for each code block extracted by the code block extraction means, based on the contents of operations in each code block, a backdoor score, which is a score indicating the possibility of each code block being a backdoor code or a score indicating the degree of impact of each code block on a system when it is executed; and output means for outputting the code blocks extracted by the code block extraction means and the backdoor score calculated for each of the extracted code blocks by the backdoor score calculation means.

Program analysis device, program analysis method, and computer-readable medium

The present disclosure aims to provide a backdoor inspection device, a user device, a system, a method, and a non-transitory computer-readable medium that enable a third party to easily verify whether software contains a backdoor. A backdoor inspection device according to the present disclosure includes: a backdoor presuming means for analyzing a function and a structure of the software, performing backdoor inspection on the software, and identifying a presumed code that is presumed to be the backdoor from the software; and a certificate issuance means for issuing a certificate that includes information about the backdoor inspection and information that associates the information about the backdoor inspection with the software.

Backdoor inspection device, user device, system, method, and non-transitory computer-readable medium

In a backdoor inspection apparatus, a static analysis unit executes static analysis processing for a backdoor on each code block included in target software to be inspected to thereby specify a first code block and a condition, the first code possibly being the backdoor and the first code block being executed under the condition. Next, the static analysis unit outputs the target software to which first information indicating the specified first code block is added and second information indicating the specified condition to a dynamic analysis unit. The dynamic analysis unit controls dynamic analysis processing for the backdoor performed on the target software to which the first information is added based on the first information and the second information.

Backdoor inspection apparatus, backdoor inspection method, and non-transitory computer readable medium

A portable imaging device is configured to: obtain video data through shooting; perform a first digital image processing on the video data; and stop the first digital image processing when performing a second digital image processing on the video data while the first digital image processing is being performed. The second digital image processing is different from the first digital image processing.

Portable imaging device

An aspect of the present disclosure provides an information processing system configured to process a captured image captured by an image-capturing apparatus including an infrared cut filter. In this information processing system, based on the captured image, a defect relating to the infrared cut filter is detected. Information on the defect is output.

Information processing system, information processing method, and memory medium

A feature estimating device includes a parser identifying means for identifying a parser, the parser being contained in software, for parsing user input and executing a relevant command, a dividing means for extracting commands form a character string in the parser and clustering control flows connecting with the extracted commands as starting points to divide a code of the software for each feature, and a feature estimating means for estimating, based on a characteristic part of each divided code, a feature for each divided code.

Estimation of features corresponding to extracted commands used to divide code of software

One aspect of the present invention relates to a dental fluoroaluminosilicate glass powder, a 50th percentile volume diameter of which is 5.0 &#x3bc;m or more and 9.0 &#x3bc;m or less, and a 10th percentile volume diameter of which is 2.4 &#x3bc;m or more.
