Screen content identification and word gliding for decryption method based on Android system terminal

Abstract

The invention discloses a screen content identification and word gliding for decryption method based on an Android system terminal. The android-based terminal comprises a terminal I, a terminal II anda server, wherein both the terminal I and the terminal II are each provided with an encryption module, a dragging module and a decryption module; the terminal I processes information into a ciphertext through the encryption module and sends the ciphertext to the server, and the server stores a corpus used as an index in advance so as to generate a unique corresponding index for the ciphertext andsend the index to the terminal II; and the terminal II decrypts the ciphertext corresponding to the index. Through the screen content identification service provided by the Android system, the problem that an existing scheme depends on and is incompatible with the system, the environment and the terminal equipment is solved, and meanwhile battery life consumption caused by the problem is reduced.

Description

technical field [0001] The invention relates to the field of communication, in particular to a screen content recognition and deciphering method based on an Android system terminal. Background technique [0002] The index-based encryption scheme allows users to encrypt plaintext content and upload it to the server, and the server will generate a unique index corresponding to the encrypted content. After that, the user can send the unique index to the user with decryption ability through any channel, that is, the user who receives the index can download the ciphertext data from the server according to the index and decrypt it. If the unique index is sent through a third-party channel, such as WeChat, SMS, email, etc., the user with decryption ability must obtain the encrypted content of the unique index in some way, so as to perform subsequent download and decryption operations. The easiest way is for the user to copy the content of the unique index and paste it into the dec...

AI Technical Summary

Problems solved by technology

Moreover, the solution of the auxiliary function monitoring input box provided by the Android system cannot guarantee perfect compatibility on some terminals. For example, on some terminals, the content of the input box cannot be obtained when the interface is switched.

In addition, existing solutions cannot obtain text content that cannot be copied, such as the name of the person who is chatting on the WeChat interface

All content that cannot be copied cannot be obtained through existing solutions

Existing solutions cannot obtain non-text content, because copying can only copy text content, so other information such as pictures on the screen, files, etc., cannot be obtained by existing solutions
