Abstract
A computer-implemented user classification method includes: obtaining, by a target terminal device, an initial user classification model from a server, in which the initial user classification model is provided by the server to multiple terminal devices, the multiple terminal devices including the target terminal device; obtaining first operation data of a registered user of the target terminal device; updating the initial user classification model based on the first operation data, to obtain an updated user classification model that is personalized for the registered user; and classifying, based on the updated user classification model, an identity of a current user of the target terminal device.
Claims20
A computer-implemented user classification method, comprising:
- obtaining, by a target terminal device, an initial user classification model from a server, wherein the initial user classification model is provided by the server to multiple terminal devices, the multiple terminal devices comprising the target terminal device;
- obtaining first operation data of a registered user of the target terminal device during a first time period, the first operation data recording one or more operations performed by the registered user on the target terminal device;
- delaying updating the initial user classification model for a predetermined amount of time after an occurrence time of the one or more operations during the first time period in order to prevent the initial user classification model from learning based on an operation of a user other than the registered user;
- the predetermined amount of time after the occurrence time of the one or more operations, updating the initial user classification model based on the first operation data, to obtain an updated user classification model that is personalized for the registered user;
- and
- classifying, based on the updated user classification model, an identity of a current user of the target terminal device.
A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:
- obtaining, by a target terminal device, an initial user classification model from a server, wherein the initial user classification model is provided by the server to multiple terminal devices, the multiple terminal devices comprising the target terminal device;
- obtaining first operation data of a registered user of the target terminal device during a first time period, the first operation data recording one or more operations performed by the registered user on the target terminal device;
- delaying updating the initial user classification model for a predetermined amount of time after an occurrence time of the one or more operations during the first time period in order to prevent the initial user classification model from learning based on an operation of a user other than the registered user;
- the predetermined amount of time after the occurrence time of the one or more operations, updating the initial user classification model based on the first operation data, to obtain an updated user classification model that is personalized for the registered user;
- and
- classifying, based on the updated user classification model, an identity of a current user of the target terminal device.
A computer-implemented system, comprising:
- one or more computers;
- and
- one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
- obtaining, by a target terminal device, an initial user classification model from a server, wherein the initial user classification model is provided by the server to multiple terminal devices, the multiple terminal devices comprising the target terminal device;
- obtaining first operation data of a registered user of the target terminal device during a first time period, the first operation data recording one or more operations performed by the registered user on the target terminal device;
- delaying updating the initial user classification model for a predetermined amount of time after an occurrence time of the one or more operations during the first time period in order to prevent the initial user classification model from learning based on an operation of a user other than the registered user;
- the predetermined amount of time after the occurrence time of the one or more operations, updating the initial user classification model based on the first operation data, to obtain an updated user classification model that is personalized for the registered user;
- and
- classifying, based on the updated user classification model, an identity of a current user of the target terminal device.
