Abstract: The invention provides a method, apparatus, device and storage medium for predicting a protein binding site. The method comprises the steps of: receiving a protein sequence to be predicted, dividing the protein sequence by using a preset sliding window and sliding step to obtain a plurality of amino acid sub-sequences, building word vectors for the protein sequence according to the amino acid sub-sequences, extracting document features from word elements, building document feature vectors for the protein sequence according to the extracted document features, extracting protein chain biological features from the amino acid sub-sequences, building biological feature vectors for the protein sequence according to the extracted biological features, classifying the amino acid sub-sequences expressed with the document feature vectors and the biological feature vectors by using a preset amino acid residue classification model to obtain amino acid residue types for the protein sequence.

Abstract: The disclosure provides a digital video content security authentication method, wherein the method comprises: a secret information embedding step of selectively modifying a pixel grayscale value for each frame image in a digital video so as to complete the embedding of 1-bit secret information; and a secret information extraction and video authentication step of carrying out secret information extraction from the digital video in which the secret information is embedded according to a key so as to realize the security authentication of the digital video content. The disclosure also provides a digital video content security authentication system. According to the technical scheme provided by the disclosure, the authentication security is improved on the basis of not influencing user experience.
