TOLKA Watermark Solution
The increase of the web-based content distribution raises the risk of revenue loss due to illegal sharing, copy and re-distribution. In order to protect the valuable content, most conditional access systems allow Broadcasters to generate a secure link to grant content access between the head distribution to the individual Set-Top box.
Tolka Watermark is a software-based solution that addresses the needs of the broadcasters to protect the content from illegal usage and revenue losses. The development of elaborate watermarking techniques is important; Tolka Watermark utilises its patented technology, Digital Signature Engine (DSE), to insert an invisible digital signature at the final destination on the distribution path making each section of the content unique each time it is decoded.
The unique digital signature is associated with the specific device which will ultimately decode the content. The digital signature is able to encrypt within the content.
If suspected content proves to be an illegal copy made from a device on a DTH operator’s network, Watermark can match the Digital Signature ID and the device associated with this signature on the network, thereby allowing easy and prompt identi cation of an illegal copy tracing the copied content to the device (eg: handheld, tablet, etc.) which decoded it.
