Kind Code:

Abstract:
An information steganography method, apparatus and device, and a storage medium, the method comprising: acquiring information to be embedded and the information length corresponding to said information; performing hexadecimal conversion on the information length to obtain information to be added; adding the information to be added to the information to be embedded to obtain target information and grouping the target information to obtain several groups of information fragments; reading pitch information of preset notes in carrier music, and writing the information fragments into the pitch information so as to obtain new preset notes; and performing note adjustments to the carrier music on the basis of the new preset notes to obtain target music. In the described method, secret information is grouped and then separately embedded into the pitch information of the preset notes of the carrier music, increasing confidentiality when transmitting the secret information, so that a decryptor cannot perceive the pitch information of what kind of note carries secret information, and thus cannot decrypt the information, thereby ensuring the security of information transmission.
