Abstract: A fingerprint recognition method that is performed by an electronic device including a first screen and a second screen includes: obtaining first fingerprint information through the first screen; extracting a first fingerprint feature from the first fingerprint information based on a fingerprint recognition mode corresponding to the second screen, and using the first fingerprint feature as a first pre-stored fingerprint template corresponding to the second screen; obtaining second fingerprint information through the second screen; and extracting a second fingerprint feature from the second fingerprint information, and determining whether the second fingerprint feature matches the first pre-stored fingerprint template.

Abstract: Techniques are described for replicating encryption keys using a write ahead log (WAL). An example method can include receiving a request from a user device to transmit encryption keys stored in a first virtual vault of a first hardware security module (HSM) of a first data center to a second virtual vault of a second HSM of a second data center, the request comprising an account identifier. The method can further include identifying a first account-specific WAL of a plurality of account-specific WALs based at least in part on the account identifier, each account-specific WAL corresponding to the first HSM, and configured to record changes to a respective virtual vault of the plurality of virtual vaults. The method can further include accessing the encryption keys from the first account-specific WAL of the first HSM. The method can further include transmitting the encryption keys to the second data center.

Abstract: A game character moving state switching method and apparatus, a device, and a storage medium are provided. The method includes: controlling a virtual character to move according to a first moving state corresponding to the first controlling region, in response to a touching operation applied to the first controlling region; controlling the virtual character to move according to the second moving state corresponding to the second controlling region, in response to a touching operation applied to the second controlling region; and controlling the virtual character to move according to a moving state corresponding to one of the controlling regions where an operating point of the touching operation is located before entering the adjusting region, in response to a touching operation applied to the adjusting region.

Abstract: A display method, an electronic device, and a computer-readable storage medium are provided. The method includes: determining a current application scenario in a case that an input of triggering display of a fingerprint icon is received; determining a target light spot based on a target parameter of the application scenario, where target light spots corresponding to different target parameters have different proportions of a red light component, different proportions of a green light component, and different proportions of a blue light component; and displaying a fingerprint icon formed by the target light spot.
