Abstract

The invention provides a cloud-based image encryption method and device, and relates to the technical field of data encryption. The method includes the steps: compressing image data and dividing the image data into first data and second data in the compressing process; storing the first data to a local terminal device; uploading the second data to a cloud server to store the second data by the cloud server. The method can solve the problems that encryption time of the current image encryption technology is long and private images are leaked as the current image encryption technology is easily cracked.

Description

technical field [0001] The invention relates to the technical field of data encryption, in particular to a cloud-based image encryption method and device. Background technique [0002] At present, with the increasing popularity of terminal devices such as smartphones with camera functions, privacy protection technologies for private images are also gradually developing. Currently, many private images are stored on terminals such as mobile phones, or directly on cloud servers. And when terminals such as mobile phones are lost, or terminals such as mobile phones and cloud servers are attacked by hackers, the privacy of private images may be leaked. Therefore, the use of digital image encryption technology to encrypt private images has become increasingly popular. [0003] However, the current digital image has a large amount of data and high redundancy. It is time-consuming to adopt the existing file encryption technology, and it is vulnerable to various cryptanalysis tools....
