Embodiment Construction

[0021] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0022] Please refer to figure 1 , is a frame line schematic diagram of a method for fast encryption of family cloud photos. The fast encryption and decryption of photos is used as an example to illustrate, and it is not limited to this in actual use.

[0023] S01, the terminal uploads photos to the cloud. The cloud is a cloud service product such as a family cloud and a private cloud.

[0024] S02, before saving the photo in the cloud, change the photo file type, that is, change the extension of the photo to the set extension, such as .jpg to .dat, and change the file type data on the file header. Different photo files refer to The file extension is converted into the corresponding file according to the matching rules.

[0025] S03, the cloud then...

Abstract

Provided is a rapid encryption method of family cloud photos. The rapid encryption method includes the steps that a terminal uploads photo files to a cloud end; the cloud end makes the matching rules of photo file extension names before the photo files are saved, and modifies the file type data in a photo file header data area based on the rules; the cloud end encrypts the photo files; and the end cloud saves the encrypted photo files. The invention further includes a rapid decryption method which achieves the aim of rapid decryption by performing reverse implementation of the matching rules of the photo files. The rapid decryption method is particularly suitable for family cloud, and the decryption speed is fast by comparing with a conventional encryption manner, network accessing efficiency is high, and the speed experience of users to browse photos can be improved.

Description

technical field [0001] The invention is applied in the field of cloud storage, especially the encryption and decryption method of the file data of Jiayou Cloud. Background technique [0002] With the development of smartphones, family clouds, and public clouds, more and more users use their mobile phones to take pictures at any time, and backup their mobile phone photos to public clouds, family clouds, private clouds and other clouds from time to time. This makes it more and more necessary to encrypt and save photos to increase privacy protection. Family cloud is a technology that has only emerged this year. The products of this technology are still in the initial stage. The performance is far from reaching the height of commercial cloud services. After all, the price varies too much. Therefore, how to tap the potential of home cloud products with low prices and general performance is the research direction for product developers. The invention discloses a brand-new method ...
