Document Type and Number:
WIPO Patent Application WO/2021/036511
Kind Code:
A1
Abstract:
A method for data encryption, storage and reading, a terminal device, and a storage medium. The method for data encryption and storage comprises: obtaining a file write operation request (S101); converting the file write operation request into a corresponding data block write request (S102); obtaining a ciphertext data block corresponding to a plaintext data block in the data block write request (S103); and storing the ciphertext data block in an actual storage area (S104). According to the method for data encryption and storage, by providing a virtual storage area, an application and a file system are prevented from directly accessing the actual storage area, but access the virtual storage area, so that the application and the file system themselves do not know that the data in the actual storage area is stored after being encrypted, so as to implement the encryption and storage of a file or data without using a storage device having encryption and decryption functions.
