An information transmission method in which in a process of transmitting information the transmission is conducted so as to increase uncertainty has not been established. Information terminals have a plurality of fixed phrases for sentence generation, and sentences are generated by inserting words, which are inputted into the information terminals or selected in relation to an event created on the information terminals, into a fixed phrase for sentence generation selected from the plurality of fixed phrases for sentence generation. For a sentence received at another information terminal via a communication channel, a determination is made as to whether or not to vary that sentence, and when variation is to be carried out, a new sentence is generated by replacing a fixed phrase for sentence generation contained in the received sentence with a different associated fixed phrase for sentence generation or by replacing a word contained in the received sentence with another word or symbol, and forwarding the generated new sentence via the communication channel to the other information terminal.

The invention discloses a video description method based on multi-feature fusion. The method is characterized in that (1) deep spatial-temporal features of a video are extracted by fusing traditional CNN features and SIFT flow features; (2) an S2VT sentence generation model with added average pooling features being video overall features is adopted to generate corresponding sentence description according to the deep spatial-temporal features extracted in the step (1); and (3) a word2vec word vector method is adopted to replace one-hot vector word representation to optimize the sentence generation model in the step (2).
