Description
Technical field
The invention belongs to cloud computing security technology areas, are related to a kind of method and system for protecting safety of image and privacy,
More particularly to a kind of encryption method blinded based on image array and method for cloud storage and system.
Background technique
Cloud is considered as the frame of Next Generation Internet development, and cloud storage provides large-scale data storage with low cost and answers
Most popular one of the technology in internet is become with service.Many well-known Internet companies, as Microsoft, Amazon, apple,
Google etc. all starts to provide the cloud storage service of charge.With gradually popularizing for cloud storage service, the privacy of user's data
Many threats are also faced with safety.
The iCloud cloud service of in August, 2012, Apple Inc. is hacked, after hacker cracks user password again,
User privacy information is stolen, certain customers' data is deleted, leads to user sensitive information leakage and loss of data.In April, 2011,
The EC2 cloud computing server of Amazon is rented by hacker, is attacked the website Sony PlayStation, causes to use on a large scale
User data leakage.In December, 2011 largest domestic developer community CSDN.NET, domestic well-known community website ends of the earth net is hacked
Visitor's attack, 40,000,000 user passwords are compromised, and clear-text way has been stored in server to user password.Cloud service is due to certainly
Opening, the resource centrality of body, a large amount of hackers do not stop to excavate the loophole of cloud service provider, it is expected that valuable data are obtained,
So that privacy leakage event takes place frequently.Meanwhile the opacity operated inside Cloud Server, cloud may deliberately collect privacy of user
Information or other dishonest behaviors, it is as lazy in saved server resource.Secret protection and data safety become cloud service
One of the bottleneck urgently to be solved of development.
Image is easiest to one of the user data of leakage as cloud, has content intuitive, and data volume is big, once leakage pair
The features such as privacy of user harm is serious.Cloud service provider considers that cloud image data has saved in plain text mostly, and cloud is not from own cost
Honest behavior can check image data, and hacker may also steal cloud data, reveal privacy of user.Therefore image is carried out
Encryption storage, makes cloud service provider that can not identify image information, has great difficulty to image decryption, and it is main to become protection image privacy
Means.In image encryption, major concern is the intensity of image encryption and the expense of encryption, decryption, including time overhead
With the size of calculation amount.It the use of more Image Encryption Scheme include at present encryption based on pixel replacement, based on secret division
Secret, the encryption based on modern password constitution, the methods of the encryption based on chaos.
Tradition by image encryption upload cloud storage during, user before image data is uploaded to Cloud Server,
First the image that store beyond the clouds is being encrypted using image encryption tool manually local, when image from Cloud Server
Locally downloading equipment and then operation is decrypted to encrypted image using tool.This scheme brings many to user
Additional operation, image encryption, decryption need to manually complete, and the speed of encryption, decryption is also to use cloud service process
The middle important link for influencing user experience.
Therefore data-privacy and safety is not only protected not to be leaked, together when cloud server end stores in image data
When should also design more convenient, efficiently encryption system cloud service for users to use.
Summary of the invention
In order to solve the above-mentioned technical problems, the present invention provides, speed high to image encryption intensity during a kind of cloud service
Degree is fast, user's operation is simple during cloud storage, key facilitates that preservation and transmission are convenient, are able to achieve multiple terminals image zooming-out
Image encryption method and system.
