Disk encryption suites generally operate on data in 512-byte sectors which are individually encrypted and decrypted. These 512-byte sectors alone can use any block cipher mode of operation (typically CBC), but since arbitrary sectors in the middle of the disk need to be accessible individually, they cannot depend on the contents of their preceding/succeeding sectors.
Contiki is designed to run on types of hardware devices that are severely constrained in memory, power, processing power, and communication bandwidth.A typical Contiki system has memory on the order of kilobytes, a power budget on the order of milliwatts, processing speed measured in megaHertz, and communication bandwidth on the order of hundreds of kilobits/second.
A subscriber, with knowledge of the watermark and how it is recovered, can determine (to a certain extent) whether significant changes have occurred within the data file. Depending on the specific method used, recovery of the embedded auxiliary data can be robust to post-processing (such as lossy compression ).
As the name suggests, in the multi-phase watermarking process the additional constraints are inserted in multiple phases of a particular design abstraction level. For example, in High-level synthesis scheduling, hardware allocation and register allocation are used to insert a watermark. The main challenge of the multi-phase watermarking process ...
The information to be embedded in a signal is called a digital watermark, although in some contexts the phrase digital watermark means the difference between the watermarked signal and the cover signal. The signal where the watermark is to be embedded is called the host signal. A watermarking system is usually divided into three distinct steps ...
An audio watermark is a unique electronic identifier embedded in an audio signal, typically used to identify ownership of copyright. It is similar to a watermark on a photograph. Digital watermarking is the process of embedding information into a signal (e.g. audio, video or pictures) in a way that is difficult to remove.
The resulting watermark is generally much clearer and more detailed than those made by the Dandy Roll process, and as such, Cylinder Mould Watermark Paper is the preferred type of watermarked paper for banknotes, passports, motor vehicle titles, and other documents where it is an important anti-counterfeiting measure.
The site relaunched on 25 December 2006 with very limited content, as well as few higher-quality clips put into a new download system in an effort to prevent hotlinking and preserve bandwidth. In addition, the relaunch saw the addition of a semi-transparent watermark to new clips added to the site, to discourage "web snatching" of clips.
