Abstract: A control method implemented by a computer configured to control a database that includes an aggregate item that records an aggregate value of transaction volume included in transaction data recorded in a blockchain, the control method including: obtaining a plurality of the transaction data recorded in the blockchain; specifying, for each of a plurality of second users who are transaction partners with a first user associated with the aggregate item, a transaction time with the first user on a basis of the plurality of transaction data; classifying the plurality of second users into a plurality of groups on a basis of dissimilarity of the transaction time; and generating the aggregate item for each of the groups in the database.

Abstract: A method for generating a file includes: executing a reception process that includes receiving text information; executing a first generation process that includes detecting a phrase that is included in the received text information and is of a specific type, generating encoded information by encoding the phrase of the specific type, and generating a first dictionary in which the encoded information is associated with the phrase of the specific type before the encoding; and executing a second generation process that includes generating a first file including a first region and multiple second regions, the first region being configured to store the encoded information, wherein a third region corresponding to the specific type among the second regions is configured to store encrypted dictionary information obtained by encrypting the first dictionary.

Abstract: An information processing apparatus accepts information corresponding to a text. The information processing apparatus refers to a storage unit that stores therein co-occurrence information on other texts with respect to the text and information corresponding to the other texts by associating both the information with the text. The information processing apparatus specifies, from among the pieces of information corresponding to the other texts, the text associated with the information corresponding to the other texts that is associated with the co-occurrence information that meets the standard.

Abstract: A non-transitory computer-readable recoding medium having stored therein a communication management program that causes a communication management device to execute a process. The process includes authenticating a terminal in response to an authentication request from the terminal, receiving a communication content destined to a communication target system, the communication target system sharing access-authentication information with the communication management device, adding a first information with the communication content, the first information corresponding to a result of the authentication request, detecting whether the communication content includes a second information that is identified by the communication target system as information added by the communication management device, deleting the second information when the second information is detected in the communication content; and transmitting the communication content to the communication target system.

Abstract: A flow generating method includes steps of; first identifying, from a plurality of occurrence events recorded as log data, numbers of occurrences of transitions for respective pairs of a transition source and destination occurrence events; second identifying occurrence order patterns and numbers of occurrences for the respective occurrence order patterns, for each of a plurality of occurrence event groups which includes two or more pairs selected in a descending order of the number of occurrences and has a different number of the occurrence events; calculating a degree of concentration and a degree of inequality to an average value of a distribution of the numbers of occurrences for the respective identified occurrence order patterns; and generating a flow of the occurrence events based on an occurrence event group in which the degree of inequality is greater than or equal to a first threshold and the degree of concentration is the lowest.

Abstract: A control method includes: receiving, by a computer, a request of a process for an information processing system from a terminal device; transmitting the received request to the information processing system; acquiring first information associated with a content of the request by referring to a memory which stores information indicating a response content for the request in association with the content of the request; receiving second information that is transmitted from the information processing system and indicates the response content for the request; extracting third information different in the second information from the first information based on the first information and the second information; and controlling whether to transmit the second information to the terminal device or transmit the third information to the terminal device based on an information amount of the third information.
