Zusammenfassung:	The invention relates to a cloud platform virtual machine mirror image protection method, system and device. The method mainly comprises the following steps: acquiring a confusion strategy according to a confidentiality level and a mirror image file specified by a virtual machine mirror image data storage request, generating a discrete mirror image data stream according to the confusion strategy, writing the discrete mirror image data stream into a cloud platform, encrypting the confusion strategy according to a preset encryption algorithm, and performing data persistence on the encrypted confusion strategy; obtaining an encrypted confusion strategy under data persistence according to a mirror image identifier specified by a virtual machine mirror image data reading request, and decrypting the encrypted confusion strategy according to a preset decryption algorithm to obtain a discrete mirror image data stream, and converging and restoring the discrete mirror image data flow according to the decrypted confusio
