judging whether the user is in a motion state or not according to the heart rate data and the speed data of the user, if so, judging whether the current time is the body-building time set by the user, if so, determining that the user is in the body-building state currently, recording the body-building time of the user, and sending the body-building time of the user to a cloud server;
when new video shooting is finished, judging whether the video shooting time is the body-building time of the user, wherein the identity ID of the facial image of the user in the video is consistent with the identity ID bound by the intelligent terminal, and if so, determining that the new video is the body-building video;
generating a public key and a private key every other preset period, sending the public key to a cloud server, generating a random key when judging that a new fitness video exists, and storing the random key and the ID of the video;
encrypting the fitness video by adopting a random key to obtain an encrypted fitness video;
encrypting the fitness time of the user, the heart rate data and the speed data in the fitness time of the user and the encrypted fitness video by adopting a private key of the user to obtain encrypted slimming data;
and sending the encrypted slimming data and the identity ID bound by the intelligent terminal to the cloud server.
8. The method for encrypting and storing the slimming cloud data of the intelligent terminal according to claim 7, further comprising the following steps:
after receiving the encrypted slimming data, the cloud server queries a public key of the user according to the ID bound by the intelligent terminal, decrypts the encrypted slimming data by using the public key, and obtains the body-building time of the user, the heart rate data and the speed data in the body-building time of the user and the encrypted body-building video after decryption is completed;
the cloud server judges whether the body-building time of the user obtained by decryption is consistent with the body-building time of the user received from the body-building state judgment module, and if so, the cloud server judges that the user identity verification is successful;
after the cloud server judges that the user identity authentication is successful, storing the decrypted user body-building time, heart rate data and speed data in the user body-building time as public data, and storing the encrypted body-building video;
and if the cloud server judges that the user identity authentication fails, the cloud server sends an authentication failure notice to the intelligent terminal, and discards the received encrypted slimming data.
