A method of protecting data applied in a computer device is provided. A designated file is encrypted by using a symmetric key to obtain an encrypted file. The symmetric key is encrypted by using a first public key of a first pair of keys and a first ciphertext is obtained. Information related to the designated file is obtained, and the related information of the designated file is uploaded to a blockchain. When decrypting the encrypted file, the related information of the designated file is downloaded from the blockchain to obtain the related information of the designated file. The symmetric key is obtained by decrypting a first ciphertext of the related information by using a first private key of the first pair of keys, and a decrypted file is obtained by decrypting the encrypted file by using the symmetric key.

Method of protecting data and computer device

A method for authenticating a software based on a blockchain implemented in an electronic device. The method includes obtaining a first identification code and a first hash value of a first software; generating a first authentication code; writing the first identification code, the first hash value, and the first authentication code into a blockchain; obtaining a second identification code of a second software to be identified and calculating a second hash value of the second software; determining whether the second hash value of the second software is the same as the first hash value; if the second hash value is the same as the first hash value, generating a second authentication code; determine whether the second authentication code is the same as the first authentication code; and if so determining that the second software is copyrighted.

Electronic device and method for authenticating software based on blockchain

A method for storing data establishes a blockchain network, a plurality of data blocks being stored on nodes of the blockchain network. The plurality of data blocks is stored in batches to form a plurality of data segments according to a preset storage period. Each data segment written to the blockchain network is encrypted and newly added data blocks are synchronized with the data blocks which are not stored in the data segment. The newly added data blocks, together with the data blocks not yet stored as the data segment are stored after the commencement of the storage period. A data storage device is also provided.

Method for data storage, device, and computer readable data storage medium

A method for detecting computer virus applied in a computing device includes obtaining a list of clean files each with file storage path and calculating a hash value of the file name corresponding to each storage path. An original status list according to the hash value and the storage path is generated, and the original status list is written in to a blockchain network. After the computing device becomes connected to a network and therefore exposed to viruses a second list of the files can be obtained and hash value of the file name is compared to the hash value in the original status list. Differences in hash values are deemed the result of a virus and the user is warned. A computing device and storage medium are also disclosed.

Method for detecting computer virus, computing device, and storage medium

A global unique device identification code distribution method includes obtaining a public key and device information of at least one Internet of things (IoT) device after the blockchain node establishes communication with the at least one IoT device, generating a random code and combining the random code with the public key and device information of the at least one IoT device to generate a global unique device identification code, and sending the global unique device identification code to the IoT device and writing the global unique device identification code and the public key of the IoT device as a pair into the blockchain network. The method is implemented in a blockchain node of a blockchain network.

Global unique device identification code distribution method

A method for controlling input in a mobile terminal can first set multiple operation modes for the mobile terminal and set multiple relation lists each of which defines a relationship between multiple predetermined functions to be executed in a corresponding operation mode and information regarding multiple predetermined touch operations input in the corresponding operation mode, and switches the operation mode of the mobile terminal among multiple operation modes, and controls the mobile terminal to execute multiple predetermined functions associated with multiple predetermined touch operations applied to a touch screen of the mobile terminal.

Mobile terminal and method for input control

A method for coupling a mobile device with a host computer of a vehicle includes establishing a connection relationship between the mobile device and the host computer, sending an invitation to the mobile device according to the established connection relationship, and coupling the mobile device to the host computer after accepting the invitation. The invitation is sent by the host computer automatically after the host computer is turned on. The mobile device couples to the host computer automatically through a corresponding coupling mechanism after accepting the invitation.
