The application discloses a container image security detection method and system based on self-defined features, and belongs to the technical field of container image security detection, and aims to solve the technical problem of how to conduct targeted security protection on image security in a multi-element security scene mode. The method comprises the following steps: constructing an image feature object and storing the image feature object in a database in the form of a registry, wherein the image feature object is a set of self-defined rules, and the rules are used to define detection behaviors for security evaluation of image features; for an image package pulled from an image warehouse, a scanner is used to analyze the metadata of the image to obtain an analysis result, and the analysis result is stored in a feature database; and the analysis result is evaluated based on the self-defined rules in the image feature object, and a security alarm is generated if the analysis result matches unsafe behaviors defined in the rules.

The aim is to allow video confirmation at the control center as needed, even when security is deactivated, while respecting user privacy. [Solution] The security system 100 includes an imaging device 10 that captures images of a predetermined security area S, a security device 30 that acquires images from the imaging device 10, a security terminal 50 that requests the security device 30 to display the images and displays the images when the request is approved, and a user terminal 60 that receives an image display signal indicating that the security terminal 50 has displayed the images. When the security device 30 approves the security terminal's request to display the images, it transmits the images to the security terminal 50 and also transmits an image display signal to the user terminal 60.

A method and system for preventing the leakage of image files from a mobile communication terminal are disclosed. An authentication-based method for preventing leakage of a mobile communication terminal image file according to an embodiment of the present invention comprises: (a) a step in which a slave terminal creates a first converted image file by inserting watermark information including a first user key identifying a master terminal user and a second user key identifying a slave terminal user into an image file captured through the camera of the slave terminal; (b) a step in which the slave terminal transmits image file information including the watermark information of the first converted image file to a master terminal to perform an authentication procedure for the access rights of the slave terminal user to the first converted image file, and receives grade information indicating the access rights grade of the slave terminal user from the master terminal; and (c) a step in which, if the access rights grade indicated in the received grade information is a first grade, the slave terminal encrypts the first converted image file, and if the access rights grade indicated in the received grade information is a second grade, the slave terminal inserts an image security program into the first converted image file to create a second converted image file.

Embodiments of the present application provide an image processing method, device and electronic equipment. In the embodiments, the initialization image corresponding to the image to be encrypted is adjusted by gradient inversion on the first loss value (used to represent the consistency degree of the image to be encrypted and the obtained initialization image corresponding to the image to be encrypted) and the second loss value (determined based on the image prediction result and the image annotation result), and the adjusted image is taken as the target encrypted image (referred to as the indirect generation of encrypted image) of the image to be encrypted. This realizes that the neural network is not directly used to encrypt the image to be encrypted when the image to be encrypted is encrypted. Moreover, the indirect generation of encrypted image guarantees the complexity of the relationship between the original image (the image to be encrypted) and the target encrypted image, thereby improving the image security.

This invention discloses a lightweight trusted container sandbox construction method, system, terminal, and medium, relating to the field of trusted computing technology. Its key technical solutions include the following steps: constructing a simplified container base environment; integrating a built-in trusted measurement mechanism; implementing kernel-level static measurement; implementing user-space dynamic measurement; and constructing a trusted sandbox for isolation. This invention solves problems such as insufficient image security, insufficient isolation, lack of trusted mechanisms, high resource consumption, and high system overhead in existing container technologies by using innovative technologies such as generating container images in a rootfs manner within the same system environment, simplifying system components, constructing a hardware-level trusted root, and implementing end-to-end trusted measurement. This achieves high security, high trustworthiness, and lightweight deployment of the container environment.
