Abstract: A method, performed by a server, of managing a non-fungible token (NFT) for content, is provided. The method includes, in response to receiving a request to issue an NFT for target content from a first electronic device of a first user who has generated the target content, generating basic metadata on the target content, uploading the generated basic metadata to a target folder generated in an interplanetary file system (IPFS), generating first ownership metadata including a content identifier (CID) of the uploaded basic metadata, obtaining a first CID of the target folder with the first ownership metadata uploaded to the target folder, and linking the obtained first CID of the target folder to an NFT uniform resource identifier (URI) of the target content.

Abstract: 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.

Abstract: 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.

Abstract: A method of a first electronic device which is connected to a fabric network supporting end-to-end encryption (E2EE) in a wireless communication system is provided. The method includes generating a fabric key based on a pre-stored first device key and a second member key received from a second electronic device, transmitting the fabric key to the second electronic device through a fabric server, which manages the fabric network, and a service server, which manages service data, encrypting service data based on the fabric key, and transmitting the encrypted data to the second electronic device through the service server, wherein the fabric key is shared with the fabric server, which is a member entity of the fabric network, and the second electronic device, wherein the encrypted data is decryptable at a member entity of the fabric network that shares the fabric key.
