SafeCast
SafeCast (software protection) was a registered trademark for Macrovision's legacy software protection system.〔Safecast trademark is dead since April 8th, 2008 according to TESS http://tess2.uspto.gov/〕 Safecast features product activation (via telephone, or through internet), and executable wrapping technology. SafeCast can be easily defeated with a keygen. (In 2015 the British company Cachebox TV Limited registered Safecast at the (UK Trade Mark Registry ) as its registered trademark for implementation of its patented technology to protect the television watershed in catch-up and timeshifted viewing. There is no connection between Cachebox and Macrovision).
==Controversy==
SafeCast exploits the lack of operating-system security in Microsoft Windows and writes directly to the boot track of the local disk as part of its operation. TurboTax, Intuit's tax-preparation software product, uses SafeCast in some versions, and the protection scheme has been blamed for a wide variety of problems with product activation and use, leading Intuit to partially remove the technology. Adobe also uses a version of SafeCast for its CS products, and has had similar but less frequent problems, particularly with certain types of disk configurations (RAID, multiple-boot), but continues to use the technology for copy protection.
