<p>The present invention provides an information processing method, comprising: a deciphering apparatus obtaining picture information in a communication text by using an optical sensor, the communication text comprising a plain text and at least one piece of picture information and the picture information being obtained according to a cipher text; the deciphering apparatus parsing the picture information to obtain the cipher text; the deciphering apparatus obtaining a deciphering policy corresponding to the cipher text; the deciphering apparatus performing deciphering processing on the obtained cipher text by using the deciphering policy to obtain character information; and the deciphering apparatus outputting the character information. By using the technical solutions of the present invention, it can be ensured that key information in a communication process is not leaked. In addition, because picture information only comprises a part of key information, compared with full text deciphering, little data needs to be parsed and deciphered by a deciphering apparatus. Therefore, the information processing efficiency is improved while ensuring the communication security.</p> |
