Abstract: The disclosure is directed to a display apparatus, including: a display configured to display a user interface for presenting an electronic program guide; and a first controller configured to: send a first request including live broadcast information to cause a server to determine replay data according to a first live broadcast program included in the live broadcast information; receive the replay data from the server, and control the electronic program guide to display a second live broadcast program with a visual replay identifier.

Abstract: Disclosed are an information interaction method and apparatus, and an electronic device. One specific embodiment of the method comprises: in response to a user logging in to a live interface initiated based on a multimedia conference, displaying a live data stream of the multimedia conference in the live interface initiated based on the multimedia conference, wherein the live data stream is generated on the basis of an interactive data stream of a participating user of the multimedia conference; receiving interactive content input by the user on the basis of the live data stream, and generating interactive information according to the interactive content; and sending the interactive information to a serving end, so as to instruct the serving end to send the interactive information to a terminal device that displays the live interface. The communication efficiency of information related to the content of a multimedia conference is thus improved.

Abstract: A data processing method includes: determining a target function corresponding to a parameter optimization request in response to the parameter optimization request; in a process of performing a parameter test on any candidate parameter by the target function, determining whether the parameter test meets a reduction condition to obtain a determination result of the candidate parameter; in response to the determination result being that the parameter test meets the reduction condition, stopping the parameter test of the candidate parameter; or in response to the determination result being that the parameter test fails to meet the reduction condition, continuing to execute the parameter test of the candidate parameter to obtain a test result of the candidate parameter.

The data node includes processing circuitry configured to: receive an anomaly estimation for a first privatized dataset, the first private dataset being based on a dataset and a first noise profile, apply a second noise profile to the dataset to generate a second privatized dataset, the second noise profile being based at least on the anomaly estimation, and optionally cause transmission of the second privatized dataset for anomaly estimation.

Abstract: A method, system and apparatus are disclosed. According to one or more embodiments, a detection node in communication with a network function virtualization, NFV, system operating a NFV stack that is logically separable into a plurality of levels including a first level and a second level is provided. The detection node includes processing circuitry configured to: translate an executed first level event sequence to at least one translated second level event sequence, and compare the at least one translated second level event sequence to an executed second level event sequence to at least in part detect inconsistencies between the at least one translated second level event sequence and the executed second level event sequence where the executed second level event sequence and the executed first level event sequence being part of a multi-level sequence flow.

Abstract: A method, computing device and system are disclosed for evaluating security of virtual infrastructures of tenants in a cloud environment. At least one security metric may be calculated for virtual infrastructures of a tenant based on information associated with at least one virtual resource of the first tenant and at least one interaction of the at least one virtual resource of the first tenant with at least one virtual resource of at least one other tenant in a multi-tenant virtualized infrastructure. At least one security parameter may be evaluated for the first tenant based at least in part on at least one of the at least one calculated security metric for monitoring a security level of the first tenant relative to the at least one other tenant in the multi-tenant virtualized infrastructure.

Abstract: An image processing method and device, a camera apparatus and a storage medium are provided. The image processing method includes: acquiring an initial image, and the initial image corresponds to an RGB data format; dividing the initial image into a plurality of image blocks; converting each image block in the plurality of image blocks from the RGB data format into a YUV data format, wherein Y is a luminance value, and U and V are chromatic value; inverting a luminance value Y of a target image block into a darkness value D, and the target image block is at least one of the plurality of image blocks; coding DUV data of the target image block and YUV data of a non-inverted image block so as to obtain target image data of the initial image.

Abstract: Systems and methods for anonymizing data are provided herein. A network node can receive privacy constraints from a data owner and utility requirements from at least one data processor. An anonymization mechanism can be selected for each data attribute in a data set, based on its specified privacy constraint and/or utility requirement, from the available anonymization mechanism(s) appropriate for its associated attribute type.

Abstract: A method, system and apparatus are disclosed. In one or more embodiments, a differential privacy, DP, node is provided. The DP node includes processing circuitry configured to: receive a query request; receive a first input corresponding to a utility parameter; receive a second input corresponding to a privacy parameter; select a baseline DP mechanism type based at least on a query request type of the query request, the first input and the second input, where the baseline DP mechanism type includes at least a noise parameter; generate a noise distribution based on the baseline DP mechanism type using a first value of the noise parameter; and determine a DP query result based on applying the noise distribution to the query request applied on a data set.
