Method and system for unlocking touch screen based on non-absolute data of number of contacts

The invention provides a method and system for conducting touch screen unlocking based on non-absolute data of the number of contacts, and belongs to the technical field of intelligent equipment encryption, and the scheme comprises the steps that a password input request interface is displayed on an equipment touch screen based on control of an equipment processor; obtaining the number of contacts in the password input request interface in real time within a password input request time interval, and constructing a password body based on the number of the contacts at different moments; wherein the password input request time interval is as follows: a touch screen signal is received for the first time in a password input request interface as a start, and a preset password input duration is met as an end; the obtained password body is compared with password bodies stored in a built-in password library, and if completely matched password bodies exist, unlocking succeeds; if not, the unlocking fails. 本公开提供了一种基于触点数
