A videotelephony image modulation apparatus and method detects an event having a possibility of information leakage by analyzing an image and provides a secured calling mode of masking all or a part of the image and transmitting a masked image obtained through the masking.

Apparatus and method for modulating images for videotelephony

A privacy region-masking device of an automobile black box system includes a masking region configuration module for constructing a masking region on an internal image of a vehicle and a key management module for creating and managing a masking key which is used for masking the masking region on the internal image of the vehicle. The privacy region-masking device further includes a masking execution module for masking the masking region on the image using the masking key, thereby generating a masked image adaptable to protect the privacy of a passenger.

Privacy region masking device and method in vehicle black box

A security management server includes an input unit for receiving image data from at least one network camera; a control unit for assigning an access authority level to each image data received via the input unit; and a storage unit for storing therein the image data along with the access authority levels assigned by the control unit. When receiving a request for a specific image data among the image data stored in the storage unit from a user having a user access authority level, the control unit compares the user access authority level and the access authority level assigned to the specific image data, and based on comparison result thereof, selectively provides the specific image data to the user.

Security management server and image data managing method thereof

An apparatus for filtering malicious multimedia data using sequential processing and a method thereof are provided. The apparatus includes: a maliciousness classification model training unit extracting a predetermined feature from at least one or more types of moving pictures and then, through machine training, generating a maliciousness determination model for each of at least one or more classes; a malicious data classification unit sequentially inputting input moving pictures for which maliciousness is required to be determined, to the maliciousness determination model, and determining the maliciousness class of the input moving pictures, based on a probability that data at a determination time of the input moving pictures belongs to a predetermined maliciousness class, and an accumulated maliciousness probability to a current time; and a malicious information filtering unit cutting off service if the maliciousness class belongs to a predetermined reference maliciousness class.
