He has made significant contributions to the fields of secure video transmission and maintenance filtering, holding a total of five patents. His innovative approaches have the potential to enhance security and efficiency in various technological applications.

Latest Patents

One of Eric Chenu's latest patents is focused on securing remote video acquisition in real time. This method and system ensure secure remote video transmission by generating a digitally encoded marker for an image. The encoded marker contains an identifier of the camera and a time variable, which is inserted into the image. The insertion process involves adding a pattern to the image in the spatial domain for each bit of the encoded marker. The conversion of this pattern into the spectral domain utilizes a predefined sub-matrix, where a frequency coefficient encodes the bit of the marker. The encoded marker can be extracted from the secure image, and the time variable is verified against a time reference to ensure the temporal freshness and origin of the secure image. A failure is flagged if any information in the encoded marker violates a security criterion.

Another significant patent by Chenu is a device and method for maintenance filtering on a flow of coded inputs and outputs. This method processes a flow of incoming messages, each with multiple inputs and outputs, and generates an outgoing message based on the state of the incoming message. The maintenance filtering device includes a calculation device, a pseudo-random generator, and a compensation table, ensuring that the state of the outgoing message reflects the state of the incoming message for a specified period.
