In the case of a remote computer, the remote computer can be connected to the user's computer through any kind of network, including a Local Area Network (LAN) or a Wide Area Network (WAN), or it can be connected to an external computer (e.g. using an internet service provider to connect via the internet).

In the several embodiments provided in this application, it should be understood that the disclosed systems, devices and methods can be implemented in other ways. For example, the device embodiments described above are only illustrative. For example, the division of units is only a logical function division. In actual implementation, there may be other division methods. For example, multiple units or components may be combined or integrated. to another system, or some features can be ignored, or not implemented. On the other hand, the coupling or direct coupling or communication connection between each other shown or discussed may be through some interfaces, and the indirect coupling or communication connection of the devices or units may be in electrical, mechanical or other forms.

In addition, each functional unit in each embodiment of the present application can be integrated into one processing unit, each unit can exist physically alone, or two or more units can be integrated into one unit. The above integrated units can be implemented in the form of hardware or software functional units.

Other embodiments of the present disclosure will be readily apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of the disclosure that follow the general principles of the disclosure and include common knowledge or customary technical means in the technical field that are not disclosed in the disclosure. . It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the disclosure being indicated by the following claims.

It is to be understood that the present disclosure is not limited to the precise structures described above and illustrated in the accompanying drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the disclosure is limited only by the appended claims.

Claims (10)

1. A public cloud storage access method, characterized in that it is applied to a home cloud storage box, the method comprising:

after receiving a storage file sent by a user terminal, generating a random key;

according to a preset encryption algorithm, encrypting the storage file through the random key to obtain an encrypted file;

uploading the encrypted file to a public cloud;

receiving receipt data sent by the public cloud, wherein the receipt data is generated by the public cloud after receiving the encrypted file, and the receipt data comprises a storage address of the encrypted file;

generating a mapping relation among the receipt data, the random key and the public cloud access password, and generating and storing file storage data, wherein the file storage data comprises a file name, the receipt data, the random key and the public cloud access password.

2. The method of claim 1, further comprising, after the generating the mapping relationship of the receipt data, the random key, and the public cloud access password, generating and saving file storage data:

generating a stored file icon according to the file storage data;

and displaying the stored file icon on a preset display interface.

3. The method of claim 2, further comprising, after the displaying the stored file icon on the preset display interface:

responding to clicking operation of a user on the stored file icon on the preset display interface, and acquiring file storage data corresponding to the stored file icon;

acquiring the encrypted file from the public cloud according to the file storage data;

decrypting the encrypted file according to the random key to obtain the storage file;

and sending the storage file to a user terminal.

4. The method of claim 2, further comprising, after the displaying the stored file icon on the preset display interface:

responding to clicking operation of a user on the stored file icon on the preset display interface, and acquiring file storage data corresponding to the stored file icon;

and sending the file storage data to a user terminal, so that the user terminal obtains the encrypted file from the public cloud according to the file storage data and decrypts the encrypted file to obtain the storage file.

5. The method according to any one of claims 1 to 4, further comprising, before said encrypting the stored file by the random key according to a predetermined encryption algorithm,:

compressing the storage file to obtain a compressed file;

correspondingly, the encrypting the storage file by the random key according to a preset encrypting algorithm to obtain an encrypted file comprises the following steps:

and according to a preset encryption algorithm, encrypting the compressed file through the random key to obtain the compressed file.

6. The method according to any one of claims 1 to 4, further comprising, after said generating the mapping relation of the receipt data, the random key, and the public cloud access password, generating and saving file storage data:

and deleting the storage file.

7. The method according to any one of claims 1 to 4, further comprising, after said generating the mapping relation of the receipt data, the random key, and the public cloud access password, generating and saving file storage data:

displaying a selection interface, wherein the selection interface comprises a stored file deleting button and a stored file not deleting button;

and responding to the selection operation of the user on the selection interface, and determining whether to delete the storage file.

8. A public cloud storage access device for use with a home cloud storage box, the device comprising:

the key generation module is used for generating a random key after receiving a storage file sent by the user terminal;

the encryption module is used for carrying out encryption processing on the storage file through the random key according to a preset encryption algorithm to obtain an encrypted file;

the uploading module is used for uploading the encrypted file to public cloud;

the receipt data are generated after the public cloud receives the encrypted file, and the receipt data comprise the storage address of the encrypted file;

and the processing module is used for generating a mapping relation among the receipt data, the random key and the public cloud access password, and generating and storing file storage data, wherein the file storage data comprises a file name, the receipt data, the random key and the public cloud access password.
