Provided are techniques for providing security for edge computing using location data. A command base location of an entity, an application identifier of the entity, and an expire date for the application identifier are determined. A message generated from the command base location and the application identifier is sent to a location authority. A signed command base location is received based on the command base location being within a jurisdiction of the location authority and a current date being before the expire date. A common key for the command base location is generated using the application identifier and the signed command base location. A public key is generated using the common key. A message is encrypted using the public key to create a cryptographic message. The cryptographic message is sent.

Providing security for edge computing using location data

Creation of a new block for a blockchain can be initiated. The new block can include a plurality of transactions. The blockchain can include a plurality of existing blocks. Transaction storage data can be generated for the new block. The transaction storage data can indicate the plurality of transactions and specify, for each of the plurality of transactions, which of a plurality of computing nodes are to keep the transaction in the new block. The generated transaction storage data can be added to the new block. The new block can be communicated to the plurality of computing nodes.

Redundancy reduction in blockchains

Test data may be generated by classifying a plurality of medical records of patients into a plurality of groups, based on at least an execution characteristic of a processing program that processes the medical records, and generating test data including at least a part of the plurality of medical records based on proportions of the number of the medical records classified into the plurality of groups.

Generation of test data for a data platform

Provided is a method for storing at least a portion of data registered in a blockchain in each of a plurality of node apparatuses, including selection of selecting whether to store data included in a block in one node apparatus among the plurality of node apparatuses, according to a characteristic of the one node apparatus; and data storage of storing at least a portion of the data included in the block in the one node apparatus, according to a result of the selection.

Blockchain technology

Provided are techniques for new command assistance. A score is generated for each of a plurality of users based on a command execution history of a command by each of the plurality of users. A command template with the command and parameters of the command is generated in an order based on the command execution history of a user of the plurality of users having a high score. In response to receiving a portion of a new command, suggestions are provided for automatically completing the command using the command template.

Command assistance

Provided are techniques for identifying diagnosis commands from comments in an issue tracking system. A new issue ticket describing an issue for a test that failed and that has a test case identifier is received. A past issue ticket for the test that has the test case identifier is identified, where the past issue ticket identifies a set of issue ticket comments. A concluding owning team change event is identified in the set of issue ticket comments. A comment with a diagnosis command that triggered the concluding owning team change event is identified in the set of issue ticket comments. A suggestion of the diagnosis command is provided by highlighting the concluding owning team change event and the comment. The new issue ticket is assigned to an owning team of the concluding owning team change event.

Identifying diagnosis commands from comments in an issue tracking system

The present invention provides a method for analyzing answers to questions in an electronic document. The method comprises reading, into a memory, the user's answers to the questions and a user's answer history information from the user's answers, wherein the user's answer history information is collected at the time the questions are answered. The method further comprises inputting, into a machine learning model, the user's answers to the questions and the user's answer history information from the user's answers to output an analysis result, wherein the machine learning model is trained, in advance, using one or more sets of training data, each set of training data comprising one or more answers to one or more questions and answer history information from the one or more answers, and a correct result which is obtained by manually judging the one or more answers to the one or more questions.

Analysis of answers to questions

An event transition model for producing test data may be generated from a plurality of event records, each event record including an event time of an instance, wherein the event transition model includes a plurality of states, each state corresponding to one or more instances of the plurality of event records, event transition probabilities between states, and event transition interval times between states.

Generation of event transition model from event records

In a mechanism for deleting blocks from a blockchain, a retention period (T), a minimum number of blocks (L), and a hash of the oldest block are defined. A participant node creates the new block including a block header. The participant node determines whether a timestamp in an oldest block in the blockchain is older than a current time plus T, and whether a current number of blocks in the blockchain is greater than or equal to L. When both are true, the participant node deletes an oldest block in the blockchain. The participant node adds a hash of an oldest remaining block and an original number of blocks of the blockchain to the block header of the new block. The participant node broadcasts a message announcing the new block to remaining participant nodes of the plurality of participant nodes.

Deletion of blocks in a blockchain

A computer-implemented method includes setting a first region on a display, the first region including a first character string, setting a second region, the second region including the first region, and dynamically generating a second character string in response to a user specifying an arbitrary position outside the first region and within the second region, the second character string is generated by changing a representation of the first character string depending on a distance between the first region and the user specified position.
