The embodiment of the application provides a cross-terminal character
input method,
system and medium. The method comprises the following steps: presetting
protocol application range data and
interaction object data, constructing a protocol architecture layer, obtaining interaction linkage rule data, performing environment
adaptation detection, obtaining customized
input method version data, activating the customized
input method and starting information receiving service, obtaining input character
information data and
processing the same, obtaining effective
ciphertext image data and capturing the same,
processing the effective
ciphertext image data, obtaining core
ciphertext data string, obtaining
plaintext data and
processing the same, obtaining standardized character data and processing the same, obtaining personalized field-input box mapping table data and processing the same in combination with a preset input box filling sequence, realizing cross-terminal character input, realizing efficient and safe character input through cross-terminal information interaction and local recognition decoding, and the information interaction process does not require
network connection, and the input convenience and
information security are taken into account.
