Disclosed are a face recognition-based video recommendation method and an apparatus, and a television. The method includes: acquiring a face image, the face image comprising a face of at least one user (S 1 ); acquiring, according to a face recognition algorithm, a face feature set of the at least one user from the face image (S 2 ); comparing the face feature set with face feature sets in an archive (S 3 ); and if the face feature set of the at least one user matches the face feature sets in the archive, displaying a first video recommendation set, and if each face feature set does not match the face feature sets in the archive, display a second video recommendation set (S 4 ). Using the method to recommend videos to users reduces operation steps of the users choosing to watch videos and provides convenience for the users to use.

A scene switching method includes: determining whether a user moves from a first scene to a second scene or not; if yes, acquiring voiceprint information of the user in the second scene; determining each device to be switched in the first scene according to the voiceprint information, and obtaining an operation state of the device to be switched; and determining an operation state of each target device in the second scene.

Disclosed are an image compression method and apparatus, and an intelligent terminal and a computer-readable storage medium. The method comprises: obtaining a target image, and determining reference pixel points corresponding to target pixel points; determining pixel difference values of the target pixel points and the reference pixel points corresponding to same; determining, according to the pixel difference values, point compression data corresponding to the target pixel points; and compressing the target pixel points according to the point compression data to obtain image compression data of the target image.

A data encryption method includes obtaining a random number set and a data mapping information, mapping the random numbers in the random number set based on the data mapping information to obtain a first encryption key, obtaining a data description information of data to be encrypted, and performing operations on the data description information based on the first encryption key to obtain an encrypted description information, mapping the data description information based on the data mapping information to obtain a second encryption key, using the first encryption key and the second encryption key to perform operations on the data to be encrypted to obtain an initial encrypted data, and generating an encrypted data corresponding to the data to be encrypted based on the random number set, the encrypted description information, and the initial encrypted data.
