Abstract

A method to anti-spy screen on mobile device is disclosed, in which, the texts on the screen are covered by a text layer which is generated automatically according to the texts it covers and the Unicode characters converting rules specified. Users could touch the layer to make the touching area disappear so that the original texts can be seen by users.

This text was extracted from a PDF file.
This is the abbreviated version, containing approximately 83% of the total text.

Problem

When people read a message or email in the public area, they would not expect others can also read the message.

Core Ideas

Overlap the message with a layer which is generated automatically according to the original texts in the message.The layer would have same number of characters with same layout in the screen with original texts of messages, but all characters are converted to Unicode characters with a specific rule so the spy could only see the un-meaningful text.

Use a virtual reading glass on the mobile screen to scan the screen, and then the original message in the area being scanned can be

clearly displayed.

The area that not being scanned would show the layer instead.

.


After a specific situation occurs, e.g. after several minutes, or after user re-open the message, the converting rules would change the layer to another new layer so that spy could not know the original text via comparing the layer.

Spy can not understand the converted Unicode characters because they are not meaningful

The layer changes every time a specific situation occurs, so the spy could not know the original text via comparing the layer.


Users still could know the original text easily as same number of characters with same layout
