Abstract: [Problem to be solved] To provide an application for setting a security for verifying the input contents and operation contents when not only opening an application file but also closing the application file. [Solution] An application available in a computer system comprises; an application file which includes an open secret code for opening each application file by the application and a close secret code for closing each application file normally by the application; an application file open program module for opening the application file under the condition that the input code is match with the open secret code; an application file close program module for closing the application file as normally under the condition that the input code is matched with the close secret code.

Abstract: To provide an application in which security settings for verifying that input content and operation content are correct are set not only when opening an application file but also when terminating and closing the application file, thereby effectively reducing erroneous input unauthorized input. A data management system of the present invention includes: a data access unit open program module in which an open secret code for opening each data access unit by the application program and a close secret code for closing each data access unit that is opened by the application program are set for each data access unit. When the authentication of the open secret code is established, corresponding data access unit are downloaded in an encrypted state, decrypted and opened. When the authentication of the close secret code is established, the data access unit in the open state is terminated, re-encrypted and closed.

Abstract: A vehicle use assistance system, in which security settings are also set in operations such as approval, confirmation, and recording of content accompanying termination of an application file uses an open passcode for opening a vehicle use assistance application 120 and a close passcode for performing normal termination of and closing a vehicle use assistance application file 130 in an open state are set for each of vehicle use assistance application files 130 used by a vehicle use assistance application 120 that assist with the use of various functions with which a vehicle 200 is equipped. A vehicle use assistance system 100 is equipped with: an application file unlocking function for receiving input of an open passcode and opening a vehicle use assistance application file 130; and an application file locking function for receiving input of a close passcode and performing normal termination of an closing a vehicle use assistance application file 130 that is in an open state.

Abstract: To execute process for determining and confirming the validity of edit data in each block of a blockchain easily and with high security, and also to execute authority verification with which it is possible to verify the authority of editing edit data and confirm the content of editing. A blockchain system comprising a plurality of computer systems, data processing applications, and a blockchain generation part for generating a blockchain in common, each block or data having open and close secret code set therefor, and each of the data processing applications being provided with an open function for opening data in a block in response to the input of an open secret code, a data editing function for editing data, and a close function for terminating and closing edited data in response to input of close secret code. The edit data and the hash value data in a block are exchanged between blockchains. Blockchain is generated in advance by the blockchain generation part.

Abstract: To provide a usage assistance system by which an authority person allows a user to use a usage object, the usage object is a movable or immovable material object; a non-material object in the form of data, an ownership right, or an intangible property right or virtual currency; or a section in which the material object or non-material object are used. An opening secret code 311, a log data unit 313 for recording usage log data, and a closing secret code 314 for correctly confirming and closing are set for each usage assistance application file 310 used by a usage assistance application program 320 that control equipment functions for the usage object.

Abstract: [Problem to be solved] To provide a financial transaction control system that makes it possible to prevent unauthorized use via skimming or identity fraud by a third party in financial transactions such as use of credit and use of debit. [Solution] A financial transaction control system in which an open secret code and a close secret code are set and registered in a financial transaction processing application file generated for each user account.

Abstract: [Problem to be solved] To provide a personal data application system with which it is possible to manage, over a cloud system or other network, persona data such as electronic clinical records, electronic health insurance cards, electronic passports, and electronic ID cards, and to thereby prevent unauthorized use thereof. [Solution] An opening authentication code and a closing authentication code, which is for performing normal termination and exiting, are set for various personal data application files that are to be used by a personal data application.
