Abstract

The present invention provides an address book backup method and system. The address book backup system comprises a blockchain network formed by a user node and a plurality of contract operation nodes, and the user node publishes an address book correction request to a blockchain network; at least one contract operation node in the blockchain network searches a corresponding public key through a pre-configured blockchain smart contract to perform decryption validation for the encrypted address book correction item; and after at least one contract operation node passes through the validation, generating an address book correction record according to the corresponding relation of the identity identifier and the address book correction item, and performing synchronization of the address bookcorrection record to other contract operation nodes in the blockchain network. The smart contract mode is employed to perform backup of the address book, the distributed backup mode is employed to reduce the risk of data loss, and the mode of encryption and decryption validation for the smart contract is employed to reduce the risk of leakage of personal data or falsification of the personal data.

Description

technical field [0001] The present application relates to the technical field of blockchain, and in particular, relates to an address book backup method and system. Background technique [0002] With the development of information technology, people's communication methods are more biased towards telephone communication or online communication, and the address book is becoming more and more important as an important part of recording the contact methods between people. In order to prevent the loss of the address book caused by various accidents, it is necessary to back up the address book. [0003] In the prior art address book backup technology, the backup is performed either in the local storage of the user terminal, or in the cloud storage space of other service providers. However, the use of local storage space for backup may easily cause the backup address book to be unrecoverable due to damage to the user terminal itself; and the use of cloud backup may easily lead to...
