Abstract: A full-vision navigation and positioning method, an intelligent terminal and a storage device, the method comprises: an intelligent terminal starting three-dimensional (3D) full-vision navigation and testing network speed by means of the background of the intelligent terminal; when the intelligent terminal detects that a current network speed m is greater than or equal to a threshold x, starting a camera to collect image information of a current streetscape and up loading the image information; and after the collected image information is compared to a 3D panoramic map, feeding back a real-time position, and continuing to carry out navigation using a 3D navigation system according to the position.

Abstract: An encrypted photographing method based on fingerprint recognition, and a system thereof are disclosed. The method may include: when detecting starting an encrypted photographing mode, obtaining an unlocking fingerprint for starting the encrypted photographing mode; when detecting a photographing instruction, generating an original photo and generating a key pair based on the unlocking fingerprint wherein the key pair may include an encryption key and a decryption key; encrypting the original photo according to the encryption key so as to generate an encrypted photo; and generating a corresponding system directory according to the decryption key, and saving the encrypted photo to the generated system directory. The present disclosure improves the security of a photo, and avoids leaking the content of an encrypted photo.
