Embodiment Construction

[0047] The present invention will be described in further detail below with reference to specific embodiments, but the scope of the present invention is not limited in any way.

[0048] like figure 1 As shown, the system mainly includes a client, a server and a cloud server. The client uploads pictures and inputs characteristic text for image retrieval. The server needs to train the model of the target object in advance. When the user uploads pictures, use the trained model. The model detects the target of the picture, generates the feature label of the picture, encrypts the picture and the feature label of the picture, and uploads the encrypted information to the cloud server; when the user enters the feature text for picture retrieval, the server The feature tags in the server side are retrieved, the retrieval results are obtained, and the retrieved results are decrypted and returned to the user side to realize the encrypted storage and encrypted retrieval of pictures. The ...

Abstract

The present invention provides a picture ciphertext storage and retrieval method and system in a cloud storage environment, including a client, a server and a cloud server: the client is used to upload pictures or query keywords to the server; the The server is used to obtain the feature label set of the picture, encrypt the picture and the feature label set, and store the obtained ciphertext picture and ciphertext feature label set on the cloud server; according to the query keyword, the generated ciphertext query request Send it to the cloud server; decrypt the ciphertext image sent by the cloud server, and return the obtained plaintext image to the client; the cloud server is used to store the ciphertext image and the ciphertext feature label set, and retrieve it through the ciphertext query request Ciphertext image. The invention protects the private information in the picture from being leaked, realizes the function of searching the picture through text keywords after the picture is encrypted and uploaded, and improves the retrieval efficiency of the image in the ciphertext environment through the retrieval feature label.

Description

technical field [0001] The invention relates to the technical field of picture processing and the field of information security, in particular to a method and system for storing and retrieving picture ciphertext in a cloud storage environment. Background technique [0002] After more than ten years of development, cloud computing has gradually moved from concept to application, providing various cloud services for more and more enterprises. Cloud storage is the data storage infrastructure of cloud computing, providing government departments, research institutes, enterprises and individual users with data storage services that are acquired on demand, elastically scalable, cost-effective, and easily accessible. While cloud storage is widely used, cloud storage security issues are becoming increasingly prominent. For example, a large amount of image data is stored in cloud storage, and these image data may contain user-related private information. At present, cloud storage se...
