Securing a remote video acquisition in real time
10482560 · 2019-11-19 · ·

A method and a system secure a remote video transmission. A marker digitally encoded in bits is generated for an image. The encoded marker contains an identifier of the camera and a time variable. The encoded marker is inserted into the image. The insertion is carried out by adding, for each bit of the encoded marker, a pattern to the image in the spatial domain. The conversion of the pattern into the spectral domain is a predefined sub matrix of which a frequency coefficient encodes the bit of the marker. The encoded marker is extracted from the secure image. The time variable is verified by comparing with the time reference and the identifier of the camera to check the temporal freshness of the secure image and the origin of same. A failure is flagged if one of the items of information included in the encoded marker violates a security criterion.
