The application includes a data processing device and method. In an embodiment, the data processing device includes a data collection unit, configured to collect data transmitted in a network, and divide the collected data, according to a predetermined feature, into known attack data and unknown attack data. The data processing device further includes a data conversion unit, configured to replace, according to a mapping database, at least a portion of the content included in the unknown attack data with corresponding identification codes. Therefore, the size of data transmitted in the network can be reduced.

Network security monitoring of network traffic

Provided are a data processing method, device, and system. The data processing method comprises: acquiring a first data packet in a local client network; determining sensitive data in the first data packet; masking the sensitive data in the first data packet, and generating a second data packet from the first data packet; and sending the generated second data packet.

Data processing method, device, and system

Embodiments provide a multimodality-based image tagging apparatus and a method for the same. The image tagging apparatus includes: a score generating unit configured to generate, for an inquiry image, multiple groups of first scores about all tags in an tagging dictionary by using a training image and multiple modalities of an image; a late-fusion unit configured to fuse the obtained multiple groups of scores to obtain final scores about all the tags; and a tag selecting unit configured to select one or more tag(s) with relatively large tag scores as tag(s) of the inquiry image according to the final scores about all the tags. With the embodiments, multiple modalities may be effectively fused, and a more robust and accurate image tagging result may be obtained.
