description The invention relates to an anti-loss cloud-intervenable key storage method, which is characterized by specifically comprising the following steps that: step 1, a main client generates a public and private key pair of the main client; step 2, the main client splits the private key into a Head part and a Body part and uploads the Head part to a cloud for storage, and the cloud establishes a database of a partial matching relationship between the public key and the Head part of the private key of the main client; and step 3, the main client splits the Body part of the private key into N parts, then distributes N shadows to N auxiliary clients, and stipulates that the Body part can be recovered as long as t auxiliary clients contribute the stored shadows therein. According to the anti-loss cloud-intervenable key storage method, the problem that the cloud storage key, the cloud responsibility and the risk are too high is solved, and the problem that the client storage key is easy to lose i
