Systems and methods of detecting an unauthorized data insertion into a stream of data segments extending between electronic modules or between electronic components within a module, wherein a data stream is encrypted with a secure encryption key for transmission, then decrypted upon receipt using a corresponding secure decryption key to confirm data transmission integrity.

The present disclosure relate generally to digital watermarking and signal encoding. Various colors can be evaluated and modified to carry an encoded or auxiliary signal.

The present disclosure relate generally to image signal processing, color science and signal encoding. Signal encoding can be applied to color image data through use of a luminance contrast sensitivity function and a chrominance contrast sensitive function. Of course, other features, combinations and claims are disclosed as well.

A method and a receiver device configured to mark a media content sequence comprising a succession of media frames. A decoder included in the receiver device selects at least two decoded consecutive media frames from the media content sequence according to a predefined information code previously stored in a configuration setting memory of the receiver device. A marking module associated to the decoder inserts a transition effect between the at least two selected decoded consecutive media frames including a preceding media frame and at least one immediately following media frame. The transition effect is retrieved from a library of transition effects stored in a memory associated to the marking module and applied on the basis of the preceding media frame and the at least one immediately following media frame. The inserted transition effect is then assigned to a secrete symbol associated to all or part of a unique identifier specific to the receiver device which outputs thus a modified sequence of media content comprising at least one transition effect between the at least two selected consecutive media frames.

In a watermark embedding method and apparatus, a layered three-dimensional model is aligned in a printing direction based on a layering direction of the layered three-dimensional model. Then, a watermark having a predetermined pattern is embedded into the aligned three-dimensional model in a direction orthogonal to the printing direction so that the embedded watermark is not associated with the printing direction.

An image synthesis method includes inputting an original image and a watermark image into a synthesis model and obtaining a synthesized image output from the synthesis model. The original image and the watermark image are respectively processed in first and second sub-models of the synthesis model and then combined, and the concatenated result is processed in a third sub-model to generate the synthesized image.

Disclosed are examples of embedding watermarks in a VDI session of a user. The watermark is based upon the user's identity and can be embedded into the VDI session to aid in the identification of data that is compromised from the VDI session. The watermark can be extracted from an image without needing the original image for extraction purposes.

A method for watermarking a three-dimensional object is disclosed. The three-dimensional object is represented by a mesh. A mesh comprises a plurality of vertices. The method further comprises computing an original thickness signature for said mesh from a plurality of thickness values, wherein a thickness value is computed for a vertex of the mesh; determining a target thickness signature, wherein the target thickness signature is a function of a watermark payload and of the original thickness signature; and modifying a position of at least one vertex of the mesh wherein a thickness signature computed for the modified mesh reaches the target thickness signature and wherein a distortion constraint between the mesh and the modified mesh is satisfied. A method for detecting a watermark in a three-dimensional object, a three-dimensional object carrying a watermark and, devices for implementing the methods are further disclosed.
