Title:
ENCODING METHOD AND APPARATUS FOR NETWORK FILE PROTECTION, AND DECODING METHOD AND APPARATUS FOR NETWORK FILE PROTECTION
Document Type and Number:
WIPO Patent Application WO/2022/193620
Kind Code:
A1
Abstract:
An encoding method and apparatus for network file protection, and a decoding method and apparatus for network file protection. Data security is improved by using a combination of encryption, decryption and signature methods for a two-dimensional code and a digital certificate, thereby effectively preventing data tampering; and characteristics of the two-dimensional code are fully utilized, the space of the two-dimensional code is reduced, and encoding steps of the two-dimensional code are reduced, thereby ensuring the security of data, and also improving the encoding efficiency. A file download address is encrypted by means of a digital certificate, thereby increasing the security and authority of the address. In addition, a URL is encrypted, thereby reducing the possibility of exposure of a plaintext address, and improving the security of a data source. During the whole process, encryption and decryption are performed by using a random number, and each file corresponds to a random key on a one-to-one basis, thereby increasing the security of a file. Moreover, during the verification process, a two-step verification mode is utilized to ensure, from multiple levels, that downloaded text is initially uploaded text, thereby greatly guaranteeing the interests of a user.
