description The invention provides an information protection method and device. The method is applied to a first terminal and comprises the following steps: receiving encrypted information sent by a second terminal; when the encrypted information is stored, obtaining target physical sign data of a first terminal user; and encrypting the encrypted information according to the target sign data to obtain secondarily encrypted target information. Through the embodiment of the invention, after the initial information is encrypted once by the second terminal, plaintext display is not carried out on the first terminal, so that a user of the first terminal can be prevented from leaking the initial information. After the encrypted information is encrypted again, a non-first terminal user can be prevented fromoperating the first terminal to leak the initial information. According to the embodiment of the invention, the personal information of the terminal user can be effectively diffused and propagated tocause leakage of the perso
