Task handoff method and related device
First Claim
1. A task handoff method, comprising:
- displaying, by a second device, prompt information, wherein the prompt information is used to inform a user that a task executed on a first device may be handed off to the second device for execution;
receiving, by the second device, a first operation of the user, and collecting a fingerprint input when the user performs the first operation, wherein the first operation is used to request execution of the task on the second device;
acquiring, by the second device, first fingerprint information and second fingerprint information by using the first device;
calculating, by the second device according to the fingerprint used when the user performs the first operation and the first fingerprint information, third fingerprint information; and
executing, by the second device, the task when the third fingerprint information matches the second fingerprint information, wherein the first fingerprint information is a sketch of a registered fingerprint of the user, and the second fingerprint information is a hash value of the registered fingerprint of the user; and
the calculating, by the second device according to the fingerprint used when the user performs the first operation and the first fingerprint information, third fingerprint information comprises;
restoring, by the second device, a fingerprint template according to the fingerprint used when the user performs the first operation and the sketch of the registered fingerprint of the user; and
calculating, by the second device, a hash value of the fingerprint template.

Abstract
A method includes: displaying, by a second device, prompt information, where the prompt information is used to inform a user that a task executed on a first device may be handed off to the second device for execution; receiving, by the second device, a first operation of the user, and collecting a fingerprint used when the user performs the first operation, where the first operation is used to request execution of the task on the second device; acquiring, by the second device, first fingerprint information and second fingerprint information by using the first device; calculating, by the second device according to the fingerprint used when the user performs the first operation and the first fingerprint information, third fingerprint information; and executing, by the second device, the task when the third fingerprint information matches the second fingerprint information.

4. A task handoff method, comprising:
-
pre-storing, by a first device, fingerprint information of a registered fingerprint of a user, and associating the fingerprint information of the registered fingerprint of the user with a task handoff function; when the user triggers the task handoff function, collecting, by the first device, a fingerprint input by the user; when the fingerprint input by the user matches the fingerprint information of the registered fingerprint of the user, acquiring, by the first device, information about multiple adjacent devices, so that the user can select, from the multiple adjacent devices, a second device for performing task handoff, wherein a login account of the first device and a login account of the second device are different, and the information about the multiple adjacent devices comprises respective login accounts of the multiple adjacent devices; displaying, by the second device, prompt information, wherein the prompt information is used to inform a user that a task executed on the first device may be handed off to the second device for execution; receiving, by the second device, a first operation performed by the user on the prompt information, and collecting a fingerprint used when the user performs the first operation, wherein the first operation is used to request execution of the task on the second device; requesting, by the second device from the first device, a sketch and a hash of a registered fingerprint of the user; receiving, by the second device, the sketch and the hash that are of the registered fingerprint of the user sent by the first device; restoring, by the second device, a fingerprint template according to the fingerprint input when the user performs the first operation and the sketch of the registered fingerprint of the user; calculating, by the second device, a hash of the fingerprint template; and executing, by the second device, the task when the hash of the fingerprint template matches the hash of the registered fingerprint of the user. - View Dependent Claims (5, 6)
