The secret information transmission model is studied and proved based on orthogonal basis space. In order to maintain the main information of the secret information's carrier, which is usually media form, paper gets the principal component of media information by Principal Component Analysis (PCA) as the orthogonal basis. Due to the reasonable compression of the carrier by PCA, paper constructs two non-complete orthogonal basis spaces based on the principal component to reduce construction's difficulty and complexity. The experiment verified the efficiency and feasibility about the model. And the form of the secret information is flexible. The capacity of the secret information is more. So it has Obvious advantages.
