AI Technical Summary

Technical Problem

During the mobile phone screen projection process, the existing technology is difficult to respond to dynamic system events in a timely manner, resulting in the possibility of leakage of sensitive content such as user communication information.

Method used

By setting preset delay parameters on the mobile terminal to delay display screen projection display data, and dynamically adjust the delay parameters according to the user operation sequence, identify and mark privacy risk areas, dynamic privacy protection of screen projection content is achieved.

Benefits of technology

While ensuring the continuity of screen projection display, it can respond to users' privacy protection needs in a timely manner, effectively prevent the leakage of sensitive information, and adaptively adjust the protection intensity according to the user's operating mode to optimize the user experience.

Abstract

A privacy protection method, terminal, medium and program product for mobile phone screen projection, which relates to the field of electronic digital data processing. The method includes: in response to the user's screen projection confirmation operation, display delay processing is performed on the projection display data according to the preset delay parameters to obtain the delayed display data, and send it to the target projection terminal; real-time acquisition of the newly added display data of the projection display data, and determination of the corresponding user operation sequence; adjustment of the preset delay parameters according to the user operation sequence to obtain the corrected delay parameters; identification of the privacy risk area of ​​the newly added display data, and generation of a privacy risk mark; in response to the user's marking operation on the privacy risk mark, risk processing is performed on the newly added display data to obtain the target display data; display delay processing is performed on the target display data according to the corrected delay parameters to obtain the newly added delay data, and send it to the target projection terminal. Implementation of this application can protect the privacy information of users when using mobile phone screen projection.
