The disclosure relates to an electronic device for generating a mnemonic phrase of a private key and an operation method in the electronic device. The electronic device may comprise a memory, a display module, and at least one processor electrically connected with the memory and the display module. The at least one processor may be configured to generate a private key and a public key, generate a first mnemonic phrase including a designated first number of words based on a structure of the private key, identify a user phrase input by a user, generate a second mnemonic phrase including a second number of words identified based on a security level obtained by analyzing the user phrase, and control the display module to display the generated second mnemonic phrase. Other embodiments are possible.

Electronic device for generating mnemonic phrase of private key and operation method in the electronic device

A method and device for non-fungible token (NFT)-based software is disclosed. A method of running the NFT-based software performed on the device includes: running the NFT-based software in response to an execution request for executing the NFT-based software; loading NFT metadata including identification information indicating the NFT-based software, identification information indicating an owner of the NFT-based software, and specified engraving data, in response to the execution request; and outputting the engraving data included in the NFT metadata based on an event occurring as the NFT-based software runs.

Method and device for NFT-based software

An electronic device and method are disclosed for managing a non-fungible token (NFT). The electronic device includes: a memory configured to store computer-executable instructions, and a processor. The processor implements the method, including: generating, a NFT for target content in response to receiving a request to register the target content from a first external electronic device, generating, for the NFT, a certification authority (CA) signature indicating that the NFT is generated by the server, and transmitting, via a communication circuitry, the NFT to the first external electronic device, wherein an ownership signature is added to the NFT, together with the CA signature, the ownership signature based on a private key of a user to which ownership of the NFT is assigned.

Method and apparatus for managing non-fungible token for digital content

An electronic device and permission control method are disclosed. The electronic device includes a display, a communication circuitry, a memory and a processor. The processor implements the method, including: receiving a first evaluation regarding usage of an access permission by at least one application from a server, via the communication circuitry, generating usage information indicating historical usage of the access permission by the at least one application, generating a second evaluation of the access permission granted to the at least one application, based at least on the usage information, determining an evaluation result based on at least one of the first evaluation or the second evaluation, and determining whether to display a user notification regarding the access permission, based on the evaluation result.

Method for controlling permission of application and electronic device supporting the same

A method of controlling a clipboard and an electronic device for performing the method are provided. The electronic device includes a display; a volatile memory including a first storage area configured to store a clipboard including existing data; an input interface; and at least one processor communicably coupled to the display, the volatile memory, and the input interface, the at least one processor being configured to: detect a read access to the existing data included in the clipboard by an application; determine whether the existing data includes personal information; and based on determining that the existing data includes the personal information, determine whether to allow the read access to the existing data by the application, based on a user input provided through the input interface.

Method of controlling clipboard and electronic device for performing the same

An electronic device and a method of operating the electronic device are provided. Data corresponding to a user input is received through a user interface of the electronic device. The data is stored in a normal area of a memory of the electronic device. A quantity of information in the stored data is identified. At least one key is selected from a plurality of keys stored in the memory, based on at least the quantity of information. The data is encrypted using the at least one key. The encrypted data and information indicating the at least one key are transmitted to a secure area of the memory, which requires access authority.

Electronic device for selecting key to be used for encryption on basis of amount of information of data to be encrypted, and operation method of electronic device
